1. Smoke and fuel injection of rotary vane vacuum pump: it means that the exhaust port of rotary vane vacuum pump is smoking and fuel injection is about during operation.
Smoke: if the pump is just started to operate with smoke signs, it is normal, and if the smoke is in the permanent disaster, it is abnormal. Handling way: smoke to clarify that the pump intake, including pipes, valves, containers have patching environment. After leak detection, punishment will be given. Smoking will be over.
Fuel injection: it is clarified that there are a large number of leakage points outside the intake port, and even the intake port is exposed to the atmosphere. The way to deal with it: seal the air inlet of the pump to make the pump run. If there is no oil injection, clarify the leakage point; the exhaust valve plate is damaged, check whether the exhaust valve plate is damaged, and change the damaged exhaust valve plate. Failure of rotary vane vacuum pump
2. Noise of rotary vane vacuum pump: This refers to the noise of the pump.
Knocking: the pump makes an irregular sound when running, like the sound of metal knocking. This is the sound of the spinner hitting the pump. This kind of environmental tension is caused by the failure of the spring between the matched discs, which is probably caused by the failure of compression or ejection. Solution: turn on the pump and check whether the spiral spring is damaged. Changed spring.
Exhaust valve noise: tension is the damage of the exhaust valve of the rotary vane vacuum pump. The way to deal with it: change the exhaust valve.
