In operation, rotary vane vacuum pumps often fail if improperly operated. For example, the vacuum degree of rotary vane vacuum pumps is reduced, fuel injection, smoke emission, oil leakage at the oil seal, noise and the like, and oil pump oil emulsification . In case of such a situation, first of all do not panic, so after the shutdown according to the fault one by one excluded. Here are a few ways to troubleshoot.
A rotary vane vacuum pump smoke and fuel injection: refers to the rotary vane vacuum pump exhaust smoke or fuel in operation.
1. Smoke, if the pump has just begun to run a smoke phenomenon, is normal, if the smoke is not normal for a long time. The solution: smoke shows the pump inlet, including pipes, valves, containers are repaired. Leakage after treatment, the smoke will end. Vortex flowmeter 2. Injection, indicating a large number of leaks outside the air inlet, or even the air inlet exposure to the atmosphere. Solution: seal the pump inlet to pump operation, if you do not fuel injection, indicating a leak; exhaust valve damage, check the exhaust valve is damaged, replace the bad exhaust valve.
Second, rotary vane vacuum pump noise: pump noise here.
1. Knocking cylinder, the pump issued an irregular sound operation, like a metal beat metal sound. This is the voice of the vane that hits the pump body. This situation is mainly caused by the spring break between mating rotors or the contraction or ejection failure. The solution: Open the pump to check whether the rotary spring is damaged. Replace the spring.
2. Exhaust valve noise, mainly the exhaust valve of the pump is damaged. Solution: a good replacement of the exhaust valve.
Third, the vane vacuum pump vacuum drop: refers to the current measured rotary vane vacuum pump than the factory index or the vacuum when the previous use of low. There are many reasons for the low vacuum level. Here are a few key facts.
1. The added rotary vane vacuum pump oil grades and the original is not the same. Different vacuum pump oil grades, as different grades of saturated vapor pressure within the oil is not the same, so the result is not the same. Solution: According to the product model specifications to replace the correct new vacuum pump oil.
2. Also due to vacuum pump oil caused by the low vacuum situation, is the vacuum pump oil emulsion color, or dirty. The solution: Put all the vacuum pump oil pump clean, replace the same type of vacuum pump oil, and to be pumping gas in the water vapor and impurities do not enter the pump.
3 was pumping gas temperature may be too high. The solution: to reduce the temperature of the gas being drawn, or you can add a corresponding heat exchanger.
4. Pump within the oil barrier or poor, the pump cavity does not maintain a certain amount of oil. Solution: check whether the smooth flow of oil, plus the same type of vacuum pump oil.
5 with the gap to change. This is the long-term exhaust gas containing dust, etc., resulting in increased wear between the rotating plate and the stator gap. Solution: check the gap is too large, replace the new parts.
Rotary vane vacuum pump troubleshooting methods:
Feature & Advantages:
1. Most filter parts are molded by FRPP, PVDF, easy to assemble and maintain.
2. Seal-lesss magnetic pump eliminates leakage of pump.
