Description

Fuel pump core with split-flow opening on pump cover
Technical field
The present invention relates to a kind of fuel pump core, particularly relate to the fuel pump core with split-flow opening on a kind of pump cover.
Background technique
At present, fuel pump product on market, when fuel pump needs one to drive stream to drive auxiliary pump or jet pump time, generally pump core main is installed threeway, to shunt the driving flow being used as jet pump or auxiliary pump to flow, or the impeller being designed to double track is to drive auxiliary pump or jet pump.
Pump core main is installed threeway by the former, flow is shunted to the driving flow being used as jet pump or auxiliary pump, so just need design threeway in addition and flexible pipe be installed the driving flow of pump core and jet pump are coupled together, produce part thus to increase, cost improves, the many assembly technologies that also causes of part are loaded down with trivial details, in addition, shunting is drawn from pump core main, pressure is very large, the pressure of fuel pump main is generally at about 4bar, so as the jet pump used time, the nozzle of jet pump must be designed to the minimum hole that diameter is less than 0.4 millimeter, otherwise main flow can be affected, and minimum hole machined difficulty is large, and easily block.
The latter is designed to the impeller of double track to drive auxiliary pump or jet pump, pump case pump cover like this must be processed into double flute form, impeller is inside and outside two circle blades, but, this not only considerably increases the difficulty of processing of impeller blade and pump case pump cover, but also work efficiency is declined, cost of parts significantly improves simultaneously.
Generally speaking, existing product both complex structures, not easily process, assemble trouble again, manufacture cost is high, also weakens the competitive ability of product in market simultaneously.
Summary of the invention
The object of the invention is to provide the fuel pump core with split-flow opening on a kind of pump cover, it not only effectively can realize forming one and drive stream to drive auxiliary pump or jet pump, and rational in infrastructure, and succinctly, easy processing, low cost of manufacture, manufacturing efficiency is high.
Solution of the present invention is to achieve the above object: the fuel pump core with split-flow opening on pump cover of the present invention comprises end cap combination, stator combination, armature, pump case, impeller and pump cover, the interior edge face of described pump cover is shaped with the oil groove of filler opening and band pore, outer ledge place in oil groove made on the interior edge face of described pump cover is provided with a driving discharge orifice, between described driving discharge orifice and filler opening, shape has angle α, the exterior edge face of described pump cover is provided with the split-flow opening that is tubular body, the driving discharge orifice that outer ledge place in oil groove on the inner port of the split-flow opening for tubular body set on the exterior edge face of described pump cover and the interior edge face of described pump cover establishes is relative and communicate, the split-flow opening place for tubular body set on the exterior edge face of described pump cover is also provided with one in order to the restraining groove of fixed drive stream operative installations.
The angle α formed between described driving discharge orifice and filler opening is 150 ° ~ 270 °.
The invention provides the fuel pump core with split-flow opening on a kind of pump cover, it mainly takes the outer ledge place in oil groove made on the interior edge face of pump cover to be provided with a driving discharge orifice, and on the exterior edge face of pump cover, set one as the split-flow opening of tubular body, the inner port of the split-flow opening for tubular body set on the exterior edge face of pump cover is relative with the driving discharge orifice that the outer ledge place in the oil groove on the interior edge face of pump cover establishes and communicate, and set by the exterior edge face of pump cover is that the split-flow opening place of tubular body is also provided with one in order to the restraining groove of fixed drive stream operative installations.
The present invention drives discharge orifice by the pump cover bottom pump core has offered one by the special position outside oil groove, fluid enters oil groove by filler opening, after liquid is brought into oil groove by impeller by filler opening, run in oil groove and increase hydrodynamic pressure by impeller, liquid moves in a circle in oil groove, because the reason of centrifugal force, the pressure of oil groove outer ledge fluid is greater than the pressure of inner side, when lateral fluid through overdrive discharge orifice time, liquid is just set from the exterior edge face of pump cover is that the split-flow opening of tubular body is spouting, another utilization is set on pump cover exterior edge face is the restraining groove fixed drive stream operative installations at the split-flow opening place of tubular body, this strand of liquid just can as the driving stream of jet pump or auxiliary pump thus.
Between the driving discharge orifice that outer ledge place in oil groove on pump cover interior edge face of the present invention establishes and filler opening, shape has angle α, the scope of angle α is 150 ° ~ 270 °, and can select to increase or reduce with the requirement of different driving stream, when driving stream traffic requirement lower, angle α can be reduced, otherwise then increase angle α.
Structural advantages of the present invention is as follows:
The driving stream of the fuel pump core 1, with split-flow opening on pump cover of the present invention is arranged on bottom pump core, make pump core when not setting up pressure, drive stream just can start working, improve the toggle speed of jet pump, drive stream as jet pump, have outstanding oil absorbency, the nozzle of corresponding jet pump can use internal diameter to be the hole of more than 0.8 millimeter, and main flow can not be affected, reliable performance.In addition, on oil-storing barrel filling time, be 30 seconds during pump core main installation threeway, be 26 seconds when pump case pump cover adopts double flute form and impeller to be inside and outside two circle blade impellers, and the present invention be only 22 seconds, and be significantly improved in performance.
What the impeller of the fuel pump core 2, with split-flow opening on pump cover of the present invention and pump cover used is traditional single groove impeller, and the impeller of cost double flute relative to difficulty of processing greatly reduces.
The design of the fuel pump core relative pump heart main shunting 3, with split-flow opening on pump cover of the present invention, greatly reduces number of spare parts and material.
Fuel pump core with split-flow opening on pump cover of the present invention is suitable for applying in fuel oil pump assembly.
