（4）Intake air control valve often fails, and medium siphon is flow backwards after causing termination of pumping, then this is opened
Self-priming fails when dynamic, frequently repairs；
（5）Liquid is easy to overflow from accessory vane shaft seal in being pumped when stoppage in transit；
（6）It is not suitable for winter outdoor work；
（7）People is needed to guard, the degree of automation is low.
Three, interior reflux self priming pump（Also referred to as vapor and liquid mixed self priming pump）Primary structure principle：It is designed in the pump housing
Pump is filled medium by gas-liquid separation chamber before starting, and defeated, separation and reflux is constantly mixed after startup by impeller, by pump suction pipe
Space vacuumizes, and achievees the purpose that medium sucts.
The problem of operation process：
（1）Separation chamber's fluid return ports are easily blocked by impurity in the pump housing, often result in self-priming failure；
（2）The efficiency of pump is low, and there are hydraulic losses and return loss；
（3）Self-priming time is longer；
（4）Self-priming performance reliable rows are not high, and suction capacity is poor；
（5）Winter outdoor work is not suitable for；
（6）People is needed to guard, the degree of automation is not high.
