Description
Technical field
The utility model is related to a kind of new screw water pump, and specifically a kind of inverse Ba type symmetrically becomes a mandarin double suction screw stem water
Pump, belongs to hydraulic technical field.
Background technology
Screw pump is positive displacement pump, and it is to change to inhale by the volume of the sealing space formed by screw rod and screw rod bushing
Enter and discharge liquid.Screw pump can be divided into single screw rod, twin-screw, three screw rods and five-screw pump according to screw rod number.Quimby pump
With pumped (conveying) medium is steady, pressure fluctuation is small, have low certain suction capacity, noise, efficiency high, long lifespan, reliable operation and
Easy to maintenance the features such as.
Quimby pump is a kind of screw pump of external toothing.It is main by a driving screw rod and a driven screw and bag
Bushing composition containing this two screw rods.By intermeshing principal and subordinate's screw rod come drawing fluid, the driving screw rod of the pump is dynamic by original
Machine is driven, and driven screw is then driven by synchromesh gear by driving screw rod.When screw rod rotates, by the engagement between screw rod with
And the cooperation in screw rod and pump housing hole, annular seal space one by one is formed in the pump housing, and suck liquid.Rotated with the continuation of screw rod,
The liquid of suction collects along axis from two ends to the center of pump, is discharged by the outlet of pump.Quimby pump is divided into closed type and non-
The major class of closed type two, Quimby pump can be mixed with transport viscosity scope very broad various media with gas-liquid delivery, solid-liquid
It is defeated, it is widely used in ship, petrochemical industry, lathe and engineering machinery.
Water pump inflow condition has a significant impact to pump performance, bad inflow condition, such as vortex, and backflow etc. can make flow velocity
Skewness, destroys intrinsic flow field so that the water (flow) direction for entering screw rod shifts, and this not only results in pump efficiency
Decline, can also deteriorate operating condition, induce cavitation erosion and hydraulic vibration, harm water pump operation safety.Inlet side is flowed simultaneously
Amount distribution is uneven, cause screw rod both sides to carry out flow inconsistent so that screw rod pressure at both sides is inconsistent, causes water body to flow back to screw rod
The capacity of returns of import increases, and reduces the emptying effectiveness of screw pump.
Granted patent CN103388580B, discloses a kind of Split mechanical seal and Quimby pump, the utility model
Two parts up and down are cutd open into by the housing to Quimby pump and screw rod pedestal and improve the sealed effect of split surface.Granted patent
CN100460681C, discloses a kind of involute tooth shape of screw of big flow Quimby pump.
Existing disclosure and granted patent pay close attention to mechanical structure, there is no Quimby pump water inlet structure patent to solve inflow condition
The influence brought when bad to pump performance and screw rod import side reflux relevant issues.
