Description
Technical field
The present invention relates to a kind of new screw water pump, specifically a kind of inverse Ba type symmetrically become a mandarin double suction screw rod water pump and its
Smooth-going current and the method for preventing backflow, belong 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 it 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.As the continuation of screw rod rotates,
The liquid of suction collects from two ends along axis 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 the very broad various media of transport viscosity scope 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 into screw rod shifts, and this not only results in pump efficiency
Decline, can also deteriorate operating condition, induce cavitation erosion and hydraulic vibration, endanger 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, and the invention passes through
Housing and screw rod pedestal to Quimby pump cut open into the effect that upper and lower two parts improve split surface sealing.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 to pump performance when bad and screw rod import side reflux relevant issues.
