What to do if smoke appears without any reason

The vacuum pump suction sewage car smoke is because the vacuum pump temperature is too high, resulting in the engine oil gasification inside the pump smoke.And the causes of vacuum pump high temperature are as follows:

1. The continuous suction operation time of the suction truck is too long.Suction truck in the suction of pollution, vacuum pump temperature is gradually rising, the longer the continuous working time, the higher the pump temperature.Generally speaking, the continuous working time of vacuum pump is 15-20 minutes. If the continuous working time exceeds 20 minutes, the temperature of vacuum pump will be too high, and there will be the possibility of smoke.

2, blue brand dirt suction truck dirt suction operation, high speed dirt suction.Sewage suction truck in sewage suction operation, is idle operation, vacuum pump speed of 800-1000 RPM.But sometimes in order to improve the suction speed, improve the suction head, some owners need to choose the oil door to increase the speed of this method.This method is simple and effective, but can cause the pump temperature to rise rapidly.

3, the vacuum pump oil is insufficient, or even no oil.The oil in the vacuum pump plays the role of lubrication and cooling, if the vacuum pump oil, or even no oil, can not play the role of lubrication and cooling, pump temperature will rise quickly, leading to smoke

4, blue brand sewage suction car in the sewage suction process, impurities into the pump body, resulting in increased friction coefficient.Impurities into the pump body, mixed with the oil, leading to oil lubrication reduced, and seriously increase the friction coefficient in the pump, friction heat, pump temperature quickly increased.

How to deal with vacuum pump smoke?

If your smudge truck vacuum pump is smoking, you need to quickly stop the operation, turn off the power lifter, smudge truck to stop the fire.If continue to force suction operations, light speed pump body wear, shorten the service life of vacuum pump.Heavy lead to damage and scrap.

After the fire stop, we need to analyze what causes the smoke of vacuum pump.

1, if it is because of the continuous operation time of the sewage suction truck is too long, you need to put the sewage suction truck fire, let the vacuum pump rest, until the temperature of the pump body down.

2, if it is because of the high speed suction pollution caused by the vacuum pump smoke, also need to suction pollution car fire, let the vacuum pump rest, until the temperature of the pump body down.

3, if the vacuum pump smoke is caused by insufficient oil or even no oil in the vacuum pump, you need to add enough oil to the oil separator.

4, if it is a foreign body into the pump body, leading to the pump internal friction coefficient is too large.You need to open the pump body, release the contaminated oil, and clean the pump body, oil and gas separator, tubing, and so on, and then put on a new oil.

The above are the reasons and treatment of smoke from vacuum pump.
