Vacuum gauge is not allowed to replace the vacuum gauge. The exhaust valve is off. Replacement of the exhaust valve. Selection of the pump. Small replacement of the pump. Local atmospheric pressure, low pressure, absolute pressure, impeller corrosion, or cavitation, replacement of impeller vibration, noise, atmospheric erosion, severe cavitation protection, working fluid. To reduce the flow rate too much, the method, the installation of the orifice plate or the flowmeter coupling is not good to re-align the concentricity of the shaft to meet the national standards or industry standards.
The foot bolts are not fixed. Fasten the dead bolts. Impeller unbalance. Rebalance the impeller.
Vacuum pump fault handling method
The pump is difficult to start. The power supply has a fault to check whether it is powered off, or the power supply is missing the foreign matter into the pump, the impeller is stuck with water, or the pump is opened to check that the packing is too tight to loosen the adjusting gland bolt. After starting the pump, slowly tighten the gland. Bolt, to a little water outflow, scale or rust is soaked with 10% oxalic acid for 30-60 minutes. The working fluid is too much to adjust the working fluid. The height is up to the shaft of the pump. The motor is tripped or the overload winding is short-circuited. Check the working fluid volume of the motor winding is too large. Working fluid inlet valve, reducing working fluid flow Exhaust pressure is too high, reducing exhaust pressure to the specified range. Excessive liquid content in the inhaled gas. Adding a separator at the inlet, or reducing the amount of working fluid. No vacuum motor steering error. Replace two. The wire has no working fluid to enter the pump. Check the working fluid system for serious air leakage and pressure detection, and repair the intake valve without opening. Open the intake valve. The vacuum is low. The working fluid flow is small.
