Water ring vacuum pump in the process of use, is connected to the substance to be extracted through the pipeline, so that the water ring vacuum pump needs to be equipped with what kind of pipeline, there is no choice trend, has become a very important issue, that today xiaobian will talk about the configuration of the pipeline, let's see.  

In order to improve the suction performance of water ring vacuum pump, pipe pump suction line should be shortened as far as possible, as little as possible to bend (elbow to use large radius of curvature), in order to reduce pipe resistance loss.  

In order to prevent cavitation of the water ring vacuum pump, the suction pipe of the pump should avoid the sac part of gas accumulation as far as possible. If it cannot be avoided, the exhaust valve of DN15 or DN20 should be set in the sac part.  When the suction pipe of the pump is vertical, if the suction pipe is configured with reducing pipe, it should be configured with eccentric reducing pipe, so as not to form an air bag.  

In order to avoid the water ring vacuum pump pipe, valve weight and pipe thermal stress generated by the force and torque exceeds the pump inlet and outlet Max allowed external load, in the vacuum pump suction and discharge pipe must be set on the pipe frame.  Max load allowed for pump nozzle shall be provided by pump manufacturer.  Vertical inlet or vertical outlet of the pump, in order to reduce the force on the pump nozzle, pipe pipe above the nozzle must be provided with a pipe frame, the plane position should be as close to the pipe mouth as possible, can use the pipe corridor girder hanging pipeline, so often put the pump arranged under the pipe corridor.  

Transportation density is less than 650Kg of liquid, such as liquefied petroleum gas, liquid ammonia, etc., the pump suction pipe should be 1/10 to 1/100 slope to the pump, so that the gas produced by gasification back into the tank, so as not to produce cavitation pump.  

Above is today about the water ring vacuum pump piping problems some explanation, we in the operation of the reason to pay attention to these problems, is to ensure the normal operation and reasonable operation of the process.
