Vacuum pump maintenance and maintenance 1. Keep the pump clean to prevent debris from entering the pump.
2. Maintain oil level.
3, improper storage, moisture or other volatile substances into the pump to affect the ultimate pressure, can be opened by the gas valve. Observe the change of the ultimate pressure. If it is invalid for several hours, the pump oil should be replaced and replaced if necessary.
Oil change method: first open the pump for about half an hour to make the oil thinner, stop the pump, drain the oil from the oil drain hole, and then open the air inlet for 10 to 20 seconds. During this time, a small amount of clean pump oil can be slowly added from the suction port. To replace the pump chamber memory oil. If the oil is dirty, repeat it again.
4, can not be mixed with diesel, gasoline and other saturated oil with a large vapor pressure, so as not to make the ultimate pressure worse. When disassembling and cleaning the parts inside the pump, it is generally wiped with gauze. When metal debris, sand mud or other harmful substances must be cleaned, it can be scrubbed with gasoline or the like, and can be assembled after drying.
5. If the pump must be disassembled for cleaning or overhaul, the disassembly and assembly steps must be taken to avoid damage to the machine.
6. Remove the connecting screw of the bearing and the pump, loosen the set screw of the pump coupling, remove the pump parts, and remove the motor as needed.
7. Install the check valve parts such as the check valve impeller, so that the check valve plane should be aligned with the oil hole of the inlet nozzle, and the rotor should be gently blocked and rotated by the hand. The oil hole should be closed when the oil hole is opened, and the valve head plane is opened. The height is 0.8 to 1.2 mm.
8. After assembly, observe the operation and limit the pressure at the pump port. If it is not suitable, it should be adjusted. When inspecting the pump, the system piping, valves and motors should also be cleaned and overhauled.
