Factors causing the water ring vacuum pump machine to be stuck

Water ring vacuum pump is a kind of equipment commonly used in industrial air pumping operation, which has a very high demand for the liquidity of the internal operation of water ring pump, so once there is a problem, it may lead to the water ring vacuum pump machine stuck and unable to work. For some reason, the motor of water ring vacuum pump is overloaded or even can't rotate, which is usually called stuck.

The reasons for the seizure of the water ring vacuum pump are: the tension spring is damaged, which causes uneven stress on the rotary vane, improper installation and partial stress, because the filter screen at the air inlet of the water ring vacuum pump is lost or damaged, which causes external dirt and metal chips to fall into the cavity of the water ring vacuum pump, and the space between the rotor, the end face of the rotary vane and the end cover of the water ring vacuum pump is too small, and the conflict heating causes the rotary vane to stretch or overheat too tightly In addition, the hardness of the spinning disc is too large, and the burr is milled together, which causes deep scratches on the end face and sintering seizure.

When the cooperation between the shaft and the sleeve is too tight, and the lubricating oil path is not smooth, the pump will be stuck for a long time due to mutual sticking and grinding. The rust in the cavity of the water ring vacuum pump will occur, and the water ring vacuum pump will operate in the environment with high humidity or pump out the wet gas, which will make the pump oil become emulsion or pump oil scale or even the viscosity of the shell pump oil is too large, and the rotor of the water ring vacuum pump will be cracked at the moment of starting; some water There are semicircle grooves on the air passage of the high and low vacuum chambers of the ring vacuum pump, the rubber plate pressed on it is too tight, and the central air passage is blocked, etc.
