Once the expansion valve of the vocs condensing and separating device fails, if the solution is not solved in time, the entire vocs condensing and separating device may be unavailable. Therefore, the failure of the expansion valve of the vocs condensing separation device needs to be solved in time, and attention is paid to maintenance.

Before servicing the expansion valve, it is necessary to observe whether the expansion valve is normally closed. The ability to open and close the expansion valve in time means that the vocs condensing separation device is used normally, and can quickly reduce the ambient temperature in a short time. Conversely, if there is a fault in the expansion valve, then the pressure inside the vocs condensing separation device appears to be high or low. If the vocs condensing separation device expansion valve failure is not handled in time, the operational safety of the vocs condensing separation device will be affected, even jeopardized. To the company’s normal use of vocs condensation separation equipment.

In order to protect the vocs condensing separation equipment evaporator and expansion valve, in order to avoid the impact of the vocs condensing separation equipment operating power is affected, the company needs regular maintenance of the expansion valve and evaporator. It can eliminate the common faults of vocs condensation separation equipment in time, and clean up the surface and internal components of vocs condensation separation equipment, which can prolong the service life of vocs condensation separation equipment and create conditions for reducing the cost of vocs condensation separation equipment.

The vocs condensing separation equipment expansion valve blockage is a frequent occurrence, the main cause of dirty plugging is the presence of impurities in the system, such as welding slag, copper filings, iron filings, fibers and so on. The reason for ice blockage is that the system contains too much moisture (moisture). For light ice blockage, hot towel can be applied to the ice block. If the ice blockage is serious and has affected the normal operation of the system, it should be replaced. Filter the dryer, re-discharge the water in the system piping, evacuate, and refill the refrigerant.

It should be noted that the expansion valve of the vocs condensing separation equipment can be solved by contacting the vocs condensing separation equipment manufacturer if it cannot be solved during installation and maintenance.
