Pressure energy from kinetic energy to higher quality convert and realize, liquid collides repeatedly between runner and impeller so that suitable one
Transfer can be converted into thermal energy and finally dissipate, this work characteristics of peripheral pump determines that its efficiency can not possibly be very high；Meanwhile
The fluid flowing of pump body is a kind of three-dimensional unsteady flow turbulent movement of complexity, is changed, normal companion as operating condition changes
There are the flow phenomenons such as flow separation, cavitation.Just because of this, peripheral pump internal flow is typically more disorderly, causes the efficiency phase of pump
To relatively low, disorderly fluidised form also influences its suction capacity.

Stablize, be conducive to the indoor gas-liquid mixed that absorbs water；On the other hand when impeller blade is near cut water, the part between blade is flowed
Body（It may be gas-liquid mixture）Enter gas-liquid separation chamber since inertia has little time to throw away impeller, flow velocity is relatively low in gas-liquid separation chamber
Segment fluid flow then by after this partial high pressure fluid volume is inhaled, the segment fluid flow retained between blade mixes, with very high speed weight
It is new to spray into suction chamber, and after being mixed with the gas of suction chamber by impeller again speedup, be transported to gas-liquid separation chamber；It is last this
A little gas-liquid mixture fluid considerable parts are thrown out of impeller, complete since the floating of bubble completes gas-liquid separation in gas-liquid separation room

Ability will be poor, and particularly requirement of the peripheral pump for assembly technology is very high, and is to ensure that it in comparable degree among these
Suction capacity.Impeller crosses conference with separation tongue gap assembling gap significantly reduces suction capacity, and assembles the too small then easy hair in gap
Raw card impeller causes peripheral pump that can not work normally, and trachoma that may be present also can be to the self-priming of self priming pump when the pump housing is cast in addition
