With the continuous improvement of living conditions in our country, the living standards of residents have been greatly developed, and a large number of discarded electrical appliances have driven the development of waste household appliances dismantling enterprises. The country's standards for the dismantling industry of used electrical appliances are becoming more and more strict, because refrigerators, air conditioners and other electrical appliances carry refrigerants that destroy the ozone layer. Therefore, it is necessary to equip the refrigerant recovery machine to recover the refrigerant substances in the electrical appliances to achieve the purpose of energy saving and environmental protection. .

 

       When the household appliance dismantling enterprise uses the refrigerant recovery machine, most of them will encounter the following situation: When the recycling machine is finished, the punching pliers are taken out, why is there still refrigerant gas discharged?

 

       Because most of the large-scale refrigerant recovery machines currently used in the dismantling plant are equipped with low-pressure pressure control (recovery to negative pressure automatic shutdown), if there is no problem with the portable recycling machine, However, if a large-scale rapid recovery device is used, in actual use, the suction force of the recovery machine is too fast, so that the inlet hose of the recovery machine reaches the set vacuum degree quickly between the refrigeration unit, and the recovery is completed. The opportunity is recycled by default and then stopped. However, in reality, the refrigerant in the air conditioner or the refrigerator has a limitation of the flow rate of the refrigerant due to the presence of the capillary. Although the front end of the capillary has been evacuated, the refrigerant in the latter still slowly comes out. This will cause the recycling machine to signal that the recycling is complete but there is still refrigerant inside.

 

        In order to be able to recycle more thoroughly, the use of the site can wait for the machine to recover. After the indicator light is on, do not rush to remove the hose, you can wait for the pressure to return to the machine to restart the work, so 2-3 rounds can also Recycle the refrigerant in the system thoroughly.

 

       Another more thorough approach is that the user can consult the refrigerant recycling machine manufacturer to customize a one-to-many recycling system, which allows one recycling machine to simultaneously recover multiple refrigeration units. It can not only solve the problem of insufficient recovery of the recycling machine, but also greatly improve the disassembly speed and increase the production capacity once and for all.

        I believe that everyone knows that for air conditioning systems, the filling machine itself carries a very large operating pressure, if the support of parts is lost, its production equipment is only a machine, and will not produce any Motivation can provide great convenience for people's lives and promote the continuous development of the whole society. However, along with the continuous innovation and development of production technology and production equipment, the filling machine is no longer a manual production, but a high-speed processing production. Although the manufacturer can get more economic profits, the wear and tear of its parts is very serious. For consumers, it is advisable to use some methods to properly lubricate and fill the filling machine, which can effectively reduce the occurrence of faults.

 

       In the process of lubrication and maintenance of its parts, its parts need to carry very high pressure during the whole high-speed operation, and its parts are prone to wear, even though its production equipment There is lubrication, but the amount of delivery exceeds the appropriate range, and regular replenishment work is required. To a large extent, it can be determined that it is stable.

 

        Reasonable maintenance of lubricating components, operators should strictly control the replenishment of lubricants in accordance with the operating frequency of the filling machine, but do a good job of pre-maintenance work to avoid any problems during its use.

       Oil compressors

       Oil compressors are commonly used air conditioning compressors or refrigerator compressors, the cost is relatively low. There is lubricating oil in the compressor, so it can only be applied to the same refrigerant recovery in the equipment. If the type or type of lubricant is different, it will cause the refrigerant to be contaminated by different oils. In the refrigerant production industry, the refrigerant will have an irreversible effect on the purity of the refrigerant because it is mixed into the pure refrigerant.

       Note: oil compressors should pay close attention to the loss of compressor oil in the recycling process, timely replenish the compressor oil to prevent oil shortage in the middle of the compressor, and can not directly recover the refrigerant liquid. It is easier to burn the compressor.

       Oil-free compressor is often said that the cylinder does not require lubricating oil compressor, its moving parts mainly use some specially designed aerospace self-lubricating composite materials, this compressor is in aerospace Contouring technology has a wide range of applications, such as compressed oxygen, hydrogen and other flammable and explosive gases. The highly durable refrigerant recovery machine is suitable for CFC, HCFC, HFC and other refrigerants because it uses an oil-free compressor and has no lubricant contamination.

       Oil-free compressor main advantages: easy to use, long life, a variety of refrigerants, maintenance-free.

        The main disadvantage: the compressor is expensive.
