Pneumatic booster pump including gas booster pump, air booster pump, gas-liquid booster pump three kinds. Each pneumatic booster pump factory, we will undergo rigorous testing after the factory, when the factory, each booster pump has been coated with anti friction, high lubricating grease.
There is no need for lubrication. But some customers in the factory will go through the compressed air refrigeration dryer (or dry machine), oil-water separator filter, compressed air dew point is low, the oil and water have been filtered using the compressed air as power, long time use of lubricating oil pump is not the original break out with dry the compressed air, resulting in a booster pump, no lubrication between the piston and cylinder to cylinder, dryness, drag and noise, affect the service life of the booster pump.
Booster pump booster pump is sealed with dry gas compressor, can not afford to pump export import 650kpa, 600kpa, after the start of the inlet pressure is constant, the pressure decreases to 550kpa, one-way valve, flow is no problem, try to close the outlet when the single pump can hold up the pressure, don't know why the outlet pressure drop after Rev. Can not increase pressure to the system. So, pneumatic booster pump oil-free lubrication, is not absolute. It depends on the situation. Any equipment needs your maintenance, no maintenance, careful maintenance will bring you a long life.
Your satisfaction is our pursuit, let us join hands in creating a better tomorrow twenty-first Century! We will as in the past cherish customers love and trust, the pursuit of perfect quality of service forever, let customer satisfaction report writing.
