Description
Technical field
This utility model is related to self-priming pump technical field, and more particularly, to a kind of twin-stage of novel intelligent no seals automatic control self-priming
Pump.
Background technology
Self priming pump belongs to self priming centrifugal pump, it have compact conformation, easy to operate, operate steadily, safeguard easily, efficiency
High, life-span length, and have the advantages that stronger suction capacity.Pipeline is not required to install bottom valve, only need to ensure to contain in the pump housing before work
Quantitation draws liquid.Different liquids can adopt unlike material self priming pump.Seal clearance before the suction lift of self priming pump, with impeller,
The factors such as the revolution of pump, separation chamber's liquid level are relevant.Before impeller, seal clearance is less, and suction lift is bigger, is typically taken as 0.3
~ 0.5 millimeter；When gap increases, in addition to suction lift declines, the lift of pump, efficiency all reduce.The suction lift of pump is with impeller
The increase of peripheral speed u2 and increase, but during to maximum suction lift, revolution increases and suction lift just no longer increased, this
When simply shorten self-priming time；When revolution declines, suction lift is then with decline.In the case that other conditions are constant, from
Inhaling height increases also as the increase of water storage height（But nor exceed the optimal water storage height of separation chamber）.In order in self-priming
Mixing wastewater with air is preferably made, the blade of impeller must be less, so that the pitch of leaf grating is increased in pump；And preferably adopt half-opened impeller（Or
The wider impeller of impeller conduit）, so more convenient for backwater in depth injects in impeller leaf grating.
Self priming pump must fill clear water or institute's pumped (conveying) medium in pump chamber when starting first, by the high speed of impeller after startup
The gas-liquid separation device of rotation and pump itself it is achieved that the sharp separation of air-liquid, constantly arranged by the air in pump inlet pipeline
Go out, in inlet tube, form vacuum, it is achieved thereby that the self-priming work process of water pump.Non-return during termination of pumping, on exit of pump pipeline
Valve cuts out rapidly, has separated the backflow of high-order medium in export pipeline, and the air admission valve on pump inlet pipeline is synchronously beaten simultaneously
Open, air enters inlet ductwork, destroys the vacuum state in inlet ductwork, thoroughly avoids the pump being caused because of siphonage
The defect of interior medium back flow emptying, remains in water pump fluid reservoir and is pumped medium material it is achieved that a drain liquid filling,
The purpose of the lifelong self-priming of water pump.But the return flow line of existing non-sealing self-sucking pump is by impeller and stator and central dividing plate
Between clearance backflow, after startup, drainage medium and reflux medium interfere, and volumetric loss is big, have impact on the operation effect of pump
Rate.
