Description

Hybrid oil transfer pump

One. technical field

The utility model relates to the diesel oil oil transfer pump that a kind of hybrid oil transfer pump, particularly automobile are used.

Two. background technique

The oil transfer pump of using on the automobile divides mechanical type oil transfer pump and electromagnetic type oil transfer pump at present.The flow of mechanical type oil transfer pump and delivery pressure are influenced by rotating speed and change greatly, exist the shortcoming of flow and pressure transient; Abrasion is big between its machinery in addition, so exist short shortcoming in working life again.Though the electromagnetic type oil transfer pump of having announced has solved the above-mentioned shortcoming of mechanical type oil transfer pump, its temperature rise, consumed power is bigger, and is not energy-conservation; Add that again its shell adopts permeability magnetic material to make, and exists the leakage field phenomenon.

Three. content of the present utility model

1. the utility model purpose is to overcome the deficiency of known technology, and a kind of output flow and pressure stability are provided, reliable performance, and the life-span is long, the hybrid oil transfer pump that temperature rise is low, the while is energy-conservation, volume is little, cost is low.The utility model relates to the hybrid oil transfer pump that a kind of automobile is used, and it is to be made of the pump housing and the fuel sucking pipe, oil suction chamber, plunger, oil extraction chamber, oil exit pipe, electric controller, electromagnetic coil, permanent magnet, the shell that are located on the pump housing.

2. the electric controller of hybrid oil transfer pump mainly is made up of monolithic microprocessor IC2, integrated package of pressure-stabilizing IC1, electric capacity, resistance, diode, voltage-stabiliser tube, field effect transistor, triode.The pin of 1 pin of IC2 and capacitor C3,3 pin of IC1 are connected, and 6 pin of IC2 are connected with an end of resistance R 2, the 8 pin ground connection of IC2; Another pin ground connection of C3; The base stage of triode V1 is connected with another pin of resistance R 2, the grounded-emitter connection of V1, and the collector electrode of V1 is connected with the end of voltage-stabiliser tube W1, an end of resistance R 3; The positive pole of another termination power of R3; The end of another termination W2 of W1 connects the end of R4 simultaneously; The grid of another termination field effect transistor V2 of R4 and the end of R5; The other end ground connection of R5; The drain electrode of field effect transistor V2 connects the end of electromagnetic coil Y1 and the positive pole of D1, the source ground of field effect transistor V2; Another termination positive source of electromagnetic coil Y1; The negative pole of D1 connects the positive pole of power supply; The end of the 1 pin connecting resistance R1 of IC1 and the positive terminal of capacitor C2, the 2 pin ground connection of IC1; The minus earth of capacitor C2; Positive terminal connecting resistance R1 and the positive source of capacitor C1, the negative pole end ground connection of capacitor C1.

3. working principle of the present utility model is as follows:

(1) electric controller working principle:

As shown in Figure 2, C1, R1, C2 form towering shape eliminator; IC1 provides IC2 stabilized power supply, and C3 plays anti-interference effect, and IC2 produces the square-wave pulse of frequency stabilization, goes to control conducting and the shutoff of triode V1, thereby conducting and the shutoff of control field effect transistor V2 finally make and produce the hybrid magnetic field of pulsation in the pump housing.Because the tube voltage drop of field effect transistor V2 is very little, the electric current of electromagnetic coil is less, so temperature rise is lower.

(2) life-span long, volume is little, energy-conservation principle:

Because: 1. the magnetic direction of permanent magnet is identical with the magnetic direction that electromagnetic coil produces, and magnetic field superposition forms hybrid magnetic field, has optimized the performance of the magnetic induction intensity of pump housing internal magnetic field.

2. the plunger in the pump housing is provided with oil groove around it, plays lubrication, reduces friction.

3. the material of the shell of pump housing use is the aluminium or the copper of non-magnetic conduction, has both prevented that electromagnet from producing the leakage field phenomenon, had good thermolysis again.

Therefore, hybrid oil transfer pump efficient height, the power of consumption is less relatively, can be energy-conservation, under the prerequisite that guarantees its quality, can reduce volume, thereby reduce cost.

(3) pump oil process is as follows:

When first pulses low of electric controller (8) arrives, electromagnetic coil (6) has electric current to pass through, plunger (9) in the pump housing moves to oil suction chamber (10) under the effect of magnetic force fast, at this moment, oil sucting one-way valve (12) in the oil suction chamber (10) is closed, oil suction chamber (10) cavity volume reduces, and pressure increases; When first pulse high level of electric controller (8) arrives, electromagnetic coil (6) outage, plunger (9) in the pump housing moves to oil extraction chamber (4) under the effect of spring, at this moment, it is big that oil suction chamber (10) cavity volume becomes, and pressure reduces, and oil sucting one-way valve (12) is opened, and the oil in the fuel tank is in fuel sucking pipe (11) enters into oil suction chamber (10).When second pulses low of electric controller (8) arrives, electromagnetic coil (6) has electric current to pass through again, plunger (9) in the pump housing moves to oil suction chamber (10) under the effect of magnetic force fast, oil extraction one-way valve (2) is opened, oil sucting one-way valve (12) is closed, oil suction chamber (10) cavity volume diminishes, and pressure increases, and the oil in oil suction chamber (10) is pressed against in the oil extraction chamber (4); When second pulse high level of electric controller (8) arrives, electromagnetic coil (6) outage, plunger (9) in the pump housing under the effect of spring to oil extraction chamber (4) fast moving, at this moment, oil extraction one-way valve (2) is closed, oil extraction chamber (4) cavity volume reduces, pressure increases, oil in the oil extraction chamber (4) is extruded the pump housing through oil exit pipe (3), simultaneously, in line check valve (12) is opened, and it is big that oil suction chamber (10) cavity volume becomes, pressure reduces, and the oil in the fuel tank is in fuel sucking pipe (11) is drawn onto oil suction chamber (10).So go round and begin again, described hybrid oil transfer pump is finished the work of pump oil.
