When checking the quality of the air discharged from the reversing valve, attention should be paid to the following three aspects:
First, understand whether the lubricating oil contained in the exhaust is appropriate. The method is to place a piece of clean white paper near the exhaust port of the reversing valve. After the valve has been working for three to four cycles, if there are only very light spots on the white paper, it indicates good lubrication;
The second is to understand whether the exhaust contains condensed water;
The third is to understand the exhaust that should not be exhausted. Is there any air leakage at the air port? A small amount of air leakage indicates early damage to the component (it is normal for the gap seal valve to have slight leakage). If the lubrication is poor, the chemical pump should consider whether the installation position of the oil mist is appropriate, whether the selected specifications are appropriate, whether the oil dripping amount is adjusted reasonably and whether the management method meets the requirements. If there is condensate water discharge, the location of the filter should be considered. It is suitable, whether the actual and selection of various types of water removal components are reasonable, and whether the condensate water management meets the requirements. The main cause of leakage is poor sealing in the valve or cylinder, insufficient air pressure, etc. When the leakage of this sealing valve is large, it may be caused by wear of the valve core and valve sleeve.
