Rotary Vane Vacuum Pump Troubleshooting

The rotary vane type vacuum pumps, in the in operation If the improper operation of the, often will appear failure, For example, Rotary Vane Vacuum Pump vacuum degrees decline in, fuel injection, smoke, oil seal Department oil spills, noise and other situation, and the the vacuum pump within the the pump oil emulsification, and and so on on phenomenon. In case this happens, first of all do not panic, shut down after 11 excluded according to the fault. Introduced here a few rule out the Analysis Method About Fault.
(1)A rotary vane vacuum pump smoke and fuel injection: Refers to the rotary vane vacuum pump exhaust ports in operation, smoke or fuel injection.
A smoke, if the pump has just begun to operate smoking is normal, if a long smoke is not normal. The solution: Smoke of the pump inlet estuary, including piping, valves, container repair. Leak after processing, the smoke will end. Vortex Flowmeter
(2) injection, the inlet estuary leakage point, and even the air inlet exposed to atmosphere. Solution: Seal pump inlet port of the pump running, if you do not fuel injection, indicating a tainted point; Damage to the exhaust valve, check the exhaust valve is damaged, the replacement of a bad exhaust valve.
Two. Rotary Vane Vacuum Pump noise: Here refers to the the noise of the the pump.
Knock the pump is running issue the irregular sound of beating metal sound, like metal. This yes the the sound of the rotary vane in the the issued by the by the hitting pump body. This is mainly between the paired rotary vane spring broken or contraction or pop-up failure in. The solution: Rotary vane spring to open the pump to check for damage. Replacement of a good spring.
