Description
Technical field
The utility model relates to a kind of fuel pump core, particularly relates on a kind of pump cover the fuel pump core with split-flow opening.
Background technique
At present, fuel pump product on the market, when fuel pump needs one driving stream to drive auxiliary pump or jet pump, generally pump core main is installed threeway, flow is shunted the driving flow that is used as jet pump or auxiliary pump, the impeller that perhaps is designed to double track drives auxiliary pump or jet pump.
The former installs threeway with pump core main, flow is shunted the driving flow that is used as jet pump or auxiliary pump, so just need in addition design threeway and installation flexible pipe that driving flow and the jet pump of pump core are coupled together, producing thus part increases, cost improves, how part causes also that assembly technology is loaded down with trivial details, in addition, draw shunting from pump core main, pressure is very large, the pressure of fuel pump main is generally about 4bar, so as the jet pump time spent, it is minimum hole below 0.4 millimeter that the nozzle of jet pump must be designed to diameter, otherwise can affect the main flow, and minimum hole difficulty of processing is large, and easily stops up.
The impeller that the latter is designed to double track drives auxiliary pump or jet pump, so the pump case pump cover must be processed into the double flute form, impeller is inside and outside two circle blades, yet, this has not only increased the difficulty of processing of impeller blade and pump case pump cover greatly, but also work efficiency is descended, cost of parts obviously improves simultaneously.
Generally speaking, existing product is complex structure both, is difficult for processing, again assembling trouble, and manufacture cost is high, has also weakened the competitive ability of product in market simultaneously.
Summary of the invention
The purpose of this utility model is the fuel pump core that will provide on a kind of pump cover with split-flow opening, and it not only can effectively be realized forming one and drive stream and drive auxiliary pump or jet pump, and rational in infrastructure, succinct, easy processing, and low cost of manufacture, manufacturing efficiency is high.
Solution of the present utility model is to achieve the above object: the fuel pump core with split-flow opening on the pump cover of the present utility model comprises the end cap combination, stator combination, armature, pump case, impeller and pump cover, be shaped with filler opening on the interior edge face of described pump cover and with the oil groove of pore, the made interior outer ledge place of oil groove is provided with one and drives discharge orifice on the interior edge face of described pump cover, form an angle α between described driving discharge orifice and the filler opening, the exterior edge face of described pump cover is provided with one and is the split-flow opening of tubular body, the driving discharge orifice that establish in outer ledge place in the oil groove on the exterior edge face of described pump cover on the interior edge face of the inner port of set split-flow opening for tubular body and described pump cover is relative and communicate, and setly on the exterior edge face of described pump cover flows the restraining groove of operative installations for the split-flow opening place of tubular body also is provided with one in order to fixed drive.
The angle α that forms between described driving discharge orifice and the filler opening is 150 °～270 °.
The utility model provides on a kind of pump cover the fuel pump core with split-flow opening, it mainly takes the outer ledge place in the oil groove made on the interior edge face of pump cover to be provided with a driving discharge orifice, and establish one in the exterior edge face of pump cover and be the split-flow opening of tubular body, the driving discharge orifice that establish in outer ledge place in the oil groove on the exterior edge face of pump cover on the interior edge face of the inner port of set split-flow opening for tubular body and pump cover is relative and communicate, and setly on the exterior edge face of pump cover flows the restraining groove of operative installations for the split-flow opening place of tubular body also is provided with one in order to fixed drive.
The utility model drives discharge orifice by having offered one at the pump cover of pump core bottom by the special position in the oil groove outside, fluid enters oil groove by filler opening, after liquid is brought into oil groove by impeller by filler opening, operation and increase hydrodynamic pressure by impeller in oil groove, 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 inboard, when outer side liquid process drives discharge orifice, liquid is just set from the exterior edge face of pump cover to be that the split-flow opening of tubular body is spouting, utilize in addition near set on the pump cover exterior edge face be the restraining groove fixed drive stream operative installations at the split-flow opening place of tubular body, the driving that just can be used as jet pump or auxiliary pump of this strand liquid is flowed thus.
Form an angle α between the driving discharge orifice that establish in outer ledge place in the oil groove on the pump cover interior edge face of the present utility model and the filler opening, 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 is low, can reduce angle α, otherwise then increase angle α.
Structural advantages of the present utility model is as follows:
1, driving stream with the fuel pump core of split-flow opening is arranged on pump core bottom on the pump cover of the present utility model, make the pump core when not setting up pressure, driving stream just can start working, improve the toggle speed of jet pump, drive stream as jet pump, have outstanding oil absorbency, it is hole more than 0.8 millimeter that the nozzle of corresponding jet pump can use internal diameter, and can not affect main flow, reliable performance.In addition, on the oil-storing barrel filling time, pump core main is 30 seconds when threeway is installed, and the pump case pump cover is 26 seconds when adopting double flute form and impeller to be inside and outside two circle blade impeller, and the utility model only is 22 seconds, and is significantly improved in performance.
What 2, use with the impeller of the fuel pump core of split-flow opening and pump cover on the pump cover of the present utility model is traditional single groove impeller, and the impeller of cost and the relative double flute of difficulty of processing greatly reduces.
The design of 3, shunting with the relative pump heart of the fuel pump core main of split-flow opening on the pump cover of the present utility model has greatly reduced number of spare parts and material.
Fuel pump core with split-flow opening on the pump cover of the present utility model is suitable for using in the fuel oil pump assembly.
