Please do not use the washing machine beyond the expiration date

The washing machine has been used for many years. What should I do if the machine parts are aging? Should I continue to use the device beyond the expiration date, or discard it and replace it with a new one? The editor reminds all users: Please do not extend the service life of the washing machine! Otherwise, personal injury or death may occur!

1. The service life of the washing machine

As for the definition of the service life of the washing machine, there is no professional answer on the market. Due to the imperfect system of the immigration agency industry and the manufacturers' protection of their own products, it is impossible to know the specific service life of the washing machine without telling by the manufacturer. At this time, it can be compared with the household washing machine. The service life of the washing machine is 8 years, so the normal service life of the industrial washing machine is 10-12 years.

2. Problems of overdue use of washing machines

Washing machines that have been used beyond the expiration date sometimes have problems such as water leakage, circuit short circuits, and body heating. Especially in hot weather, long-term use is more likely to cause the body to overheat, increasing the possibility of spontaneous combustion; the aging of the electrical components inside the washing machine is prone to leakage, resulting in the water in the washing machine shell or the washing tub being charged, and electric shock tragedies are prone to occur during use.

3. How to deal with expired washing machine services

A good way to deal with expired washing machines is to have them "scrapped" and replaced with new ones.

With the development of cities and the improvement of people's living standards, there are more and more hotels and restaurants. The washing machines in these hotels discharge a large amount of washing wastewater every day, and the washing wastewater contains a large amount of eutrophic substances. If it is not treated, it will be discharged directly, which is easy to cause nutrient pollution of surface water, destroys water resources, and especially affects the growth and reproduction of aquatic plants and animals. Therefore, in the current situation of water shortage, we should attach great importance to environmental protection, so it is very necessary to treat washing machine wastewater.

According to the laundry process, washing machine wastewater mainly includes laundry wastewater cleaning and dry cleaning wastewater. Laundry wastewater accounts for about 30% of the total wastewater, and laundry wastewater accounts for about 60%. Dry wastewater accounts for about 10% of the total wastewater, and the wastewater has different characteristics: laundry wastewater contains a large number of short fibers and detergent foam, which is turbid and sometimes very dark in color. The foam contains less suspended matter, higher transparency, less dry wastewater, and the water quality is slightly better than washing wastewater.

The current wastewater treatment processes mainly include biochemical treatment, membrane treatment, physical and chemical treatment, etc. Although the biochemical treatment process has a low operating cost, the treatment effect is unstable and requires the cultivation and domestication of biological bacteria. The water temperature of the wastewater also requires the membrane treatment process to have an ideal treatment effect, but the membrane treatment has poor water output capacity and high investment costs. According to the characteristics of washing machine wastewater, it is advisable to select physical and chemical treatment processes. The treatment effect of this process is stable and the equipment investment cost is low.

In order to ensure the effluent quality of washing machine wastewater treatment, the following measures are taken in the physical and chemical process:

(1) Concentrate the washing machine wastewater to ensure that the source of the wastewater treated by the process is relatively stable.

(2) When the wastewater is discharged into the concentration pool, add a screen to eliminate short fibers and some suspended matter in the water.

(3) According to the water quality characteristics of the washing machine wastewater, select a suitable flocculant for flocculation and sedimentation to reduce the color and remove suspended matter and some harmful impurities.

(4) After the washing machine wastewater is flocculated and precipitated, the upper clear liquid is mechanically filtered to ensure that the effluent is clear and transparent.

(5) Add drugs, oxidation, sterilization, and disinfection to further treat the mechanically filtered effluent to ensure that the effluent quality meets the reuse water quality indicators.

(6) After adjusting the pH value, the product enters the clean water tank and can be used for the wash in the washing machine.

Each set of washing machines allows manufacturers to reduce costs and bring great profits, which should not be explained by specific figures, because this phenomenon is too obvious. In fact, whether the washing machine has been maintained for a certain period of time or not, there will always be some minor problems. It may be that the parts are rusted, the gears are stuck, or the control system collapses. We cannot deny the convenience and speed brought by the washing machine, but if you treat it well, it will give you better benefits.

So how do we avoid accidents with washing machines in daily life? Washing machines are generally used in large quantities. If there are many impurities between clothes, there will be a lot of clothes to be washed. If these impurities are sediments, etc., if they are not cleaned, it is easy to gradually penetrate into the motor through the gap. If the motor is broken, the whole machine will stop. Therefore, after use, please wash the machine with natural water to prevent damage to the machine due to sediments, etc.

Secondly, when using a washing machine to wash clothes, you often encounter the situation where the clothes are long. If you put them in the washing machine to wash, it is easy to tie all the clothes together, making the washing degree of each piece of clothing uneven, or the rotation of the drum is very laborious. So before cleaning, it is good to tie the clothes a little with a long belt to prevent this phenomenon.

Finally, the water temperature is worth paying attention to. We know that the dissolution of detergent requires appropriate water temperature. If the detergent is not dissolved, the cleaning effect may not be strong after dissolution. Professional washing requirements suggest that the water temperature must be controlled between 0-40 degrees. Too high or too low water temperature is not conducive to the detergent or cannot perform at its.

People often say that machines also have feelings. The better you treat them, the more they will return to you. So if we think about it this way, the washing machine can send back its true power. In fact, the focus is not to make things more troublesome but to make things go more smoothly, so try the washing machine and let the washing machine help you make big money.

1. Now society is highly industrialized, so we can see factories everywhere in the city. These factories are important to the whole society and play a huge role in promoting the development of society.

2. But the larger the factory, the more employees are needed. Therefore, the laundry problem of these employees has become a problem. It is for this reason that industrial washing machines are very popular at present. Why is this product as popular as ordinary washing machines? This is the product advantage of industrial washing machines.

3. Industrial washing machines are very common, simple, and easy to maintain washing machines, but they have a huge difference in washing volume from ordinary household washing machines. However industrial washing machines still have advantages. For example, industrial washing machines have great advantages in degreasing. We all know that the current industrial labor is very tight, so many people engaged in industrial work are relatively dirty, so their clothes at work are more likely to be stained with oil, which has become a distress for many workers now, but with the industrial laundry design, the worries of workers are perfectly solved. All these stains in work can find a solution through washing machines.

4. Advantages of industrial washing machines in protecting clothing: Workers will cause certain damage to their clothes when they are working, which is already a serious problem. If these clothes are seriously damaged when washing, the service life of the clothes will be relatively short. This has caused a very serious waste phenomenon. Since industrial washing machines use industrial laundry solvents, the water content of industrial washing machines is relatively small. Because the materials of industrial clothing are some fibers, they are prone to swelling when exposed to water, which will cause damage to the clothes. However, if very little water is used, this phenomenon can be completely avoided, and the clothes can be protected to a certain extent.

5. Protect the color of clothing: Many people may not know that the color of industrial clothing is very important. Many people think that there is no reason why industrial clothing is so bright, but this is not the case. The color of industrial clothing is to make it easy to distinguish on certain occasions.

The bed sheet ironing machine is a mechanical device that does not produce much vibration during work, so its installation should be different from other types of washing machines, and more attention should be paid to the corresponding energy reference rather than shock and vibration prevention. The following small section will introduce it to everyone.

1. In order to ensure the effectiveness of operation and the convenience of subsequent maintenance and repair work, the installation location of the bed sheet ironing machine should be kept at a certain distance from the surrounding area. Generally speaking, about 2 meters is more appropriate.

2. Since the laundry room is a humid place, in order to prevent the scalding machine from rusting and damage, we should put a mat at least 20 cm high on the bottom to prevent the danger of being soaked in water during future use.

3. After determining the position, please use a level to level the reel, install the grounding wire, and do the corresponding lightning protection work.

4. The power supply of the bed sheet ironing machine should be 360V industrial power supply. Do not use a low-voltage power supply. When the power supply voltage is unstable, the corresponding circuit breaker and current transformer should also be installed to prevent the occurrence of leakage accidents.

5. For steam-heated sheet ironing machines, when introducing the corresponding gas source, the entire gas supply pressure should be kept stable, and it should not be used under overpressure or underpressure.

6. The air inlet pipe of the sheet ironing machine should be connected from the upper part of the main pipe because the upper end of the main pipe is steam and the lower end is a water vapor mixture, which is not conducive to normal heating. At the same time, in order to improve the quality of the steam supply, the end of the main pipe is closed with a pipe drain valve and connected to the condenser pipe.

7. Especially when installing the external exhaust system, attention should be paid to avoid the increase of pressure loss and the reduction of exhaust volume due to diameter error, elbow form error, exhaust pipe connection error, etc., thereby reducing the ironing capacity of the machine.

Through the implementation of the above 7 steps, I believe you can easily install the ironing machine, and as long as you do the above points, it can not only guarantee the reliability of the installation to a large extent but also bring a lot of convenience to our future use.

1. When the washing machine has started the laundry task, do not continue to add detergent, because the washing machine has already turned the original washing powder into solution, and then continuing to add will only waste washing powder, and will not enhance the cleaning effect.

2. The clothes have not been soaked in the washing machine for a long time. Because the dirt on the fabric of the clothes only needs to be soaked in water for about 15 minutes, and the dirt on the clothes soaked during this time is the easiest to clean. If you soak for too long, the clothes will turn yellow instead of being washed cleaner.

3. It is not suitable to overuse or overuse small materials. Overuse means using a washing machine that is too large to wash too few clothes. This is a waste of resources, and it is also easy to cause the body space, causing the machine to idle, and thus make the machine bad. The large-scale use of small materials means that the small body contains too many clothes, which makes the equipment unable to work properly and causes the equipment to get stuck. We should choose a suitable washing machine according to our washing needs!

Washing machines are prone to corrosion and rust during long-term electrochemical reactions. Understand the maintenance methods of stainless steel washing machines to effectively prevent washing machines from rusting and aging, and extend the service life of washing machines. The specific maintenance methods of stainless steel washing machines are as follows:

What are the specific maintenance methods for washing machines?

1. Clean and maintain the washing machine regularly. When cleaning and wiping the surface of the washing machine, do not use steel wool and abrasives, which can easily scratch the surface of the washing machine and cause corrosion.

2. If there is oil on the surface of the stainless steel washing machine, wipe it with a soft cloth and add neutral detergent to wipe it.

3. Some stainless steel washing machines have trademark films on the surface, which can be cleaned with weak detergent or alcohol.

4. When the surface is stained with bleach, it should be washed with water immediately, and then mixed with ammonia solution or neutral sodium carbonate solution for cleaning and wiping, which can effectively prevent the washing machine from rusting and corrosion.

5. If you want the stainless steel washing machine to have a gorgeous style, you must follow the specific maintenance methods of the washing machine to make it beautiful and clean and extend its service life!

In the process of using a large dryer, there are some things we need to do well in order to really master the correct method, and then get better results, which is very important to us. Correctly understand the specific method of use so that we can better play its role in the future use process.

Before using a large dryer, we need to check whether the different parts of the machine are really intact, and then evenly place the items to be washed in the toilet. If you find that there are some problems in society, you must solve them in time, and don't operate directly, otherwise it will affect the next operation and cause damage to society.

In the process of using a large dryer, during the startup process, choose the right time. After the time stops, the power will be cut off. After the dryer naturally slows down for a period of time, it will stop running. In this process, we must really ensure that the equipment stops stably, and then take out the things inside. During use, some people still need to rotate inside the key, but they go directly to take things, which can easily cause harm to themselves and is also a very wrong way. You need to understand and really pay attention to safety.

High-quality industrial dryers use automatic control devices. By adjusting the control panel, the drying time, drying temperature and cooling time can be adjusted to achieve self-cleaning and drying. Purchasing drying equipment from well-known manufacturers is the key to ensuring that the drying effect meets the standards. Therefore, it is necessary to make a reasonable choice, at least the benefits it can bring will be obvious.

The use of automatic control devices to achieve control of industrial dryers will have better results when washing towels while taking into account disinfection and drying. In many cases, it will help to clean cloth and grass, such as towels, and choose more advanced equipment to assist in cleaning and drying efficiency.

The performance and stability of equipment provided by different manufacturers vary greatly, and the technologies used are also different. Therefore, we need to have more understanding when choosing equipment. Only in terms of quality can we have good results and outstanding performance in service level, so it is necessary to make a reasonable choice.

In summary, the industrial dryer is automatically controlled and the effect is very good. Therefore, when we choose, we also need to have more understanding, so that we can have a good performance at the overall level. Only in terms of quality can we have a good performance, and then we can quickly improve the quality.

With the development of science and technology, folding machines have been more and more widely used in our daily lives. Recently, many users have consulted the editor. When buying a folding machine, how to check the structure of the whole machine to make it more comprehensive? Here, the editor will answer your questions through the following three points.

1. Check the material thickness of the entire frame

Whether it is a bed sheet folding machine or a towel folding machine, the two side plates of the frame are load-bearing parts that support multiple drive shafts. They are made of profiled steel plates with a thickness of not less than 8mm. Different types of folding machines may be different, namely bed sheet folding machines and large towel folding machines.

2. Check the roundness and straightness of each drive shaft

You can ask the folding machine manufacturer what kind of steel pipe is used for the drive shaft, whether it is ordinary steel pipe, welded pipe, or cold-drawn pipe, and how to process it to ensure its roundness and straightness. When the folding machine is running, you can also observe whether the drive shaft bounces and whether the conveyor belt is tight. As long as there is bounce and tightness, the drive shaft is not round or straight.

3. Observe the assembly quality of the folding machine drive shaft

Check the parallelism of the drive shaft. The center distance of the two drive shafts, that is, the center distance of the two shafts, can be measured from the left and right sides of the folding machine on the plate, and the error between the two should be less than 3mm. The center distance of each shaft can also be measured on the front and rear side panels of the horizontal frame to determine the parallelism of the assembly.

Check the parallelism of the left and right or front and rear side panels of the entire frame. When the folding machine is running without load, it can be observed whether the side panel has slight vibration along the axial direction of the drive shaft. If there is vibration, it means that the side panel is not strong enough or there is a non-parallel factor. The axial distance between the upper and lower corners of the side panel can also be measured statically, and the error value should be less than 5mm.

Check the assembly quality of the entire frame bearing. It can be observed when the folding machine is running without load. Listen carefully to the sound of each drive shaft bearing on the left and right sides of the plate and the front and rear sides of the horizontal plate. It should be a uniform slight hissing sound, and there should be no irregular cracking sound. Otherwise, check the bearing status of each drive shaft separately or repeat the above inspection.

There are many manufacturers of dryers, but there are great differences in production technology levels. Therefore, when choosing equipment, you should fully understand the technical strength of the equipment manufacturer. Professional equipment manufacturers will be able to master the technical accumulation and material selection, thereby effectively improving the performance of the equipment.

Faced with numerous dryer manufacturers, evaluation from multiple angles is the key to obtaining good quality. Only in terms of quality can we have a good performance, and then in terms of overall benefits. Therefore, when making product selections, it must be determined in a targeted manner.

Enterprises that develop and manufacture towel drying equipment can design according to the needs of the use occasion so that the equipment can have a good effect on the drying of fabrics. Only in terms of quality can we make customers recognize it. Therefore, we still have to pay more attention to it, so that we can be more prominent in actual benefits.

In short, the selection of dryer manufacturers should be evaluated from the aspects of technical reserves, manufacturing materials, etc. When the performance of the equipment is relatively stable, the overall reliability will be better. Whether it is the drying speed of the fabric or the uniformity of heating, the performance of the equipment can be very outstanding.

The maintenance of washing machines should be carried out in different time periods

Through the observation and testing of experts, it is found that reasonable and effective timely maintenance of washing machines can not only improve the service life of washing machines but also provide users with operating efficiency. So how to maintain washing machines in time? Experts believe that you can divide it into the following aspects:

1. Daily maintenance of washing machines

1. Here, daily maintenance of washing machines refers to daily maintenance of washing machines. The operation can refer to the following steps:

2. After the cleaning cycle, the button collector should be cleaned to reduce the load of the pump, prevent pump blockage, and extend the service life of the pump.

3. After every three washing cycles, the cotton collector should be cleaned to improve airflow and shorten drying time.

4. Reduce the attachment of cilia to the recovery condenser and reduce corrosion to the recovery condenser.

5. Check the three pneumatic components of the washing machine every day, drain the water, prevent water from entering the solenoid valve and air valve, and damage them prematurely.

6. When the oil level is insufficient, add lubricating oil to ensure that each bearing is fully lubricated and extend the bearing life.

7. Check the working pressure of the washing machine filter regularly. When the pressure reaches or exceeds 1.5-2kg/cm~2, clean the filter, reduce the pump outlet pressure, and extend the service life of the pump.

8. Clean the distillation tank every 5-8 times to increase the distillation speed, reduce the corrosion of the bottom plate sludge, and extend the service life of the distillation tank.

2. Monthly maintenance of washing machines

The monthly maintenance of washing machines here refers to the monthly maintenance of washing machines. The operation can refer to the following steps:

1. Check the belt tension of the washing machine every month to ensure that the washing speed and drying speed are normal, check the belt wear, and replace it in time.

2. Check the pH value of the polyester solvent. If the pH value is found to be reduced, it should be adjusted in time to prevent the dry cleaning machine from corrosion and extend the service life of the washing machine.

3. Thoroughly clean the cilia around the machine to prevent the cilia from clogging the air duct and reduce the corrosion of the dirt adsorbed by the cilia on the machine.

4. Check the performance of each steam trap, clean the filters of the steam pipe and cooling water pipe, improve the efficiency of the machine, and save energy.

5. Check and clean the solvent pump to prevent the dirt blocked in the pump from wearing the pump impeller, increasing the pump outlet pressure, and damaging the seal.

3. Annual maintenance of washing machines

The annual maintenance of washing machines here refers to comprehensive maintenance of the washing machine once a year. The operation can refer to the following steps

1. Thoroughly clean the cilia connected to the cold coil, hot coil, and airflow channel to reduce the corrosion of dirt on the machine.

2. Drain the oil-water separator of the washing machine to ensure the normal separation of oil and water. Clean the distillation condenser and related pipelines. It is good to use sodium bicarbonate water to clean it to neutralize the acid in the dry cleaning oil and extend the service life of the machine.

3. Thoroughly clean the solvent tank of the washing machine, thoroughly remove the dirt in the bottom box, and extend the service life of the washing machine.

4. Check whether the washing machine motor is running normally and clean the dust in the motor.

After the explanation of the above three categories and 17 knowledge points, I believe that the maintenance methods of the washing machine at each time period are quite clear. I hope that you who use washing machines can apply these methods to daily operations.
