The cause of the water ring vacuum pump hot - and ruled out

we know that, as a result of water ring vacuum pump work environment, the overall performance of the pump is very good, but will be hot after use for a long time. Some hot temperature may be due to long running. The result is more than the specified value. In order to ensure that thoroughly solve the problem of fever, we must first know what the reason is, second, we must master the methods of discharge, and try to do better.

1, the reason of water ring vacuum pump heating

1, the water ring vacuum pump of the circulating water quantity is too small. Circulating water has two purposes: one is the cooling vacuum pump; The other is a cooling pump. The other is on the impeller rotates in water pump water ring cavity formation. The air in 020 - when the impeller rotation 0 under compressed air.

2, suction gas temperature is high, the circulating water to reduce 30 degrees. After a day's run continuously, vacuum pump like in the home hot water kettle. Scale in pump. After the impeller is difficult to operation, the friction secondary and generate heat.

1, water ring vacuum water pump heating way, took out the motor passport, rotary motor fan wing is flexible, rotation is flexible, there is no scale, and operating difficulties, remove the pump exhaust pipe, and use hand lantern. See inside to see if there is any proportion, and generate the proportion. This will cause the impeller is difficult, hot destroy motor, and mechanical seal of the spring is easy to lock for scaling on the shaft. Face after wear, cannot automatically added, which leads to the mechanical seal leakage and heat damaged motor.

2, vacuum water pump, air water pump, allow a small amount of liquid. If absorbing material containing large amounts of water, shall be installed in the front buffer tank, inhale large amounts of water can make the impeller fracture.

3, water ring vacuum pump pumping gas of high temperature, the use of water as the circulating water, or use the condenser cooling gas.

note: vacuum pump must be equipped with overload protector, in order to prevent the motor due to overload heat destroyed. Connecting pipe can not refine 70%. Pipeline is too thin, poor drainage can lead to electrical heating.

under normal circumstances, the water ring vacuum pump heating is the cause of the above points. It also gives a method to eliminate, but don't blindly follow above points. Some vacuum pump, after all, have a special reason, ask the operator to enhance professional knowledge and judgment, and to find out the causes of the problem correctly, so that in the later use to solve the problem smoothly.
