Description
Technical field
The present invention relates to a kind of Centrifugal water pump, specifically, is a kind of many volute chambers of single-stage centrifugal water pump.
Background technique
Motor car engine extensively adopts Centrifugal water pump, and when water pump vane rotated, the cooling liquid in the water pump was driven rotation together by impeller, and under action of centrifugal force, was thrown toward the edge of water pump cover, obtained certain kinetic energy simultaneously, flowed out from outlet pipe then.Pressure descends because cooling liquid is thrown out of in the center of impeller, and the cooling liquid in the radiator flows into the impeller center through intake pipe under the differential pressure action at water pump import and impeller center.
Existing one-stage centrifugal formula water pump can only realize in single loop that liquid circulation flows, and new-energy automobiles such as pure electric automobile, hybrid vehicle, fuel cell car all need two or more liquid circulation loop to realize the heat management of power system usually.This just makes that space availability ratio, manufacture cost and the system reliability of heat management system are all not fully up to expectations.
Therefore existing automobile Centrifugal water pump structure exists above-mentioned all inconvenience and problem.
Summary of the invention
The object of the invention; A kind of many volute chambers of single-stage Centrifugal water pump that is used for electric vehicle is provided; Realization overcomes the defective of existing technology; Efficiently utilize single centrifugal water pump, to satisfy the needs of the more liquid circulation of new-energy automobile loops such as pure electric automobile, hybrid vehicle, fuel cell car to power system.
For realizing above-mentioned purpose, technical solution of the present invention is:
A kind of many volute chambers of single-stage Centrifugal water pump that is used for electric vehicle comprises the axle that stretches into the pump housing from a side, and water seal and centrifugal impeller is housed on axle successively, and the periphery of centrifugal impeller is a spiral case, it is characterized in that:
At the opposite side of the pump housing,, offer a water intake in the inlet of centrifugal impeller at the center of spiral case; In the snail road of spiral case; Near the outer ring of centrifugal impeller some and snail road are set and revolve the partition bulkhead of shape with height, spiral case is separated into relatively independent some volute chambers, and each volute casing is drawn the mouth of a river respectively.
Adopt the present technique scheme; During the impeller rotation; Fluid gets into water pump by water intake; Some and the snail road that after impeller obtains energy, is provided with by the outer ring near centrifugal impeller is introduced relatively independent some volute chambers with the partition bulkhead that height revolves shape; Export through outlet separately then; The a plurality of fluids of water pump output supplies different circuit to use because of the different flow that has nothing in common with each other---the lift characteristics that show of the drag characteristic of each self-loop, and a plurality of volute chambers are directly proportional with the traffic demand of each self-loop to the subtended angle
in axle center.
Further, two partition bulkheads of symmetry are set in the snail road of spiral case, spiral case is separated into two volute chambers that volume is identical, upwards draws upper water-out respectively and draws lower outlet downwards.General optional two of using always.
Further, in the snail road of spiral case, some and snail road are set revolve the partition bulkhead of shape with height, adjacent two partition bulkheads form subtended angle, and each subtended angle angle is different, and spiral case is separated into relatively independent, some volute chambers that volume is different.
Further again, in the snail road of spiral case, be provided with two and revolve the partition bulkhead of shape with height with the snail road, two subtended angle angles are unequal.
The two volute chamber Centrifugal water pumps of single-stage of the present invention can also adopt following technical measures further to realize.
After adopting technique scheme, the two volute chamber Centrifugal water pumps of single-stage of the present invention have the following advantages:
1, the cooling waterpump in the initiative tide of motorism management system of related domain adopts one, unites two into one;
2, a radiator replaces original two or more radiators, effectively improves structural compactness and system reliability;
3, significantly reduce manufacture cost, make that the water pump volume is little, in light weight, cost reduces about 50%.
4, for automobile industry, the weight reduction of Centrifugal water pump ability, the reduced volume effect is great, and the development of favourable acceleration automobile industry has outstanding creativeness.
