Abstract
The invention discloses a sliding-vane-type oil delivery pump with springs. The sliding-vane-type oil delivery pump comprises a rotor, an eccentric ring, sliding vanes, an oil delivery pump cover and the sliding valve springs. The rotor is installed on a driving shaft of a high-pressure oil pump, sliding grooves are formed in the outer circle of the rotor in an equidistant mode, one sliding vane which can move in the sliding groove is placed in each sliding groove, the sliding vane springs are installed between the bottoms of the sliding grooves and the sliding vanes, the sliding vanes sliding along the sliding grooves are tightly attached to the inner cavity wall of the eccentric ring, the eccentric ring is arranged on the outer edge of a whole body in a sleeved mode, and the eccentric ring is attached to the oil delivery pump cover, wherein the whole body is formed by assembling the rotor, the sliding vanes and the sliding vane springs. In the sliding-vane-type oil delivery pump with the springs, the sliding vanes slide along the sliding grooves, under the effect of centrifugal force, the sliding vanes run in the mode of being tightly attached to the inner wall of the eccentric ring, and when the centrifugal force is insufficient, the centrifugal force can be compensated through the effect of the sliding vane springs. The sliding-vane-type oil delivery pump overcomes the defect that the inner portion of a diesel engine leaks, the low-speed adaptability of the oil delivery pump is enhanced, and due to the fact that the requirement for element machining precision is not high, the product cost is lowered.
Description
Technical field
The invention belongs to diesel car and manufacture field, relate in particular to the component that use on a kind of high-pressure fuel pump of diesel engine.
Background technique
High pressure co-rail system is a kind of novel electronic Control for Diesel Engine fuel injection system, comprises the parts such as high pressure oil pump, common rail pipe, oil sprayer and electronic control unit.Because high pressure co-rail system needs to supply with the diesel oil of sufficient amount and sufficiently high pressure power in diesel engine High Rotation Speed, and control oil inlet quantity and change flexibly with the needs of diesel engine, therefore need an oil transfer pump to provide the pressure of 0.5MPa for high pressure co-rail system.
At present general oil transfer pump is gear fuel supply pump, as the CP3 pump of the HPO pump of Japan electric coating company and German doctor company; The oil transfer pump of this structure is to utilize Principles of Gear Connection to diesel supercharging, due to machining error, has all the time this gap between gear and pump case, causes the internal leakage of diesel oil, has reduced oil transportation efficiency; The requirement on machining accuracy of part is high, and common process equipment is difficult to reach.In the last few years, although released vane fuel supply pump on market, be all large-scale, Integral-structure type, can not be used on high pressure co-rail system, and low speed adaptability is poor.
Summary of the invention
The object of the invention is to for the deficiencies in the prior art, a kind of vane fuel supply pump with spring is provided, slide plate is fitted in by centrifugal action and on eccentric hoop, realizes pump oil; And use spring has increased the adaptability of low speed, in the time of low speed, also can meet the demand of pump oil mass; Reduce the requirement to part processing precision, and can auto-compensation slide plate or eccentric hoop wearing and tearing.
The object of the invention is to be achieved through the following technical solutions, a kind of vane fuel supply pump with spring, comprise rotor, eccentric hoop, slide plate, cover of feed pump and sliding blade spring, wherein, described rotor is arranged on the live axle of high pressure oil pump, the equidistant chute that is provided with in outer ring of rotor, in each chute, all place the slide plate that can move in chute, sliding blade spring is arranged between chute bottom and slide plate, tightly the fit internal chamber wall of eccentric hoop of the slide plate sliding along chute, the rotor of eccentric strap after assembling, on slide plate and sliding blade spring outer, eccentric hoop pastes on cover of feed pump.
Further, described eccentric hoop is 1-3mm to the degree of eccentricity of live axle.
Further, the quantity of described slide plate and sliding blade spring is 4-8.
Advantage of the present invention and beneficial effect are:
1. the present invention adopts sliding vane to replace gear engagement supercharging oil transportation, is close to eccentric hoop internal chamber wall owing to changing sheet, has avoided the generation of internal leakage phenomenon;
2. the wearing and tearing of slide plate of the present invention and eccentric hoop can auto-compensation, and part processing precision is less demanding, has reduced the cost of processing;
3. the present invention has increased the adaptability of low speed, also can meet the demand of pump oil mass in the time of low speed.
Brief description of the drawings
Fig. 1 is structural representation of the present invention;
In figure, rotor 1, eccentric hoop 2, slide plate 3, cover of feed pump 4, sliding blade spring 5.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
Embodiment 1:
As shown in Figure 1, rotor 1 is arranged on high pressure oil pump live axle, rotor 1 surrounding is equidistant is provided with 4 chutes, slide plate 3 is arranged in chute, slide freely along chute, slide plate 3 is tightly fitted on the internal chamber wall of eccentric hoop 2, and sliding blade spring 5 is arranged between chute bottom and slide plate 3, eccentric hoop 2 is enclosed within on rotor 1, slide plate 3 and sliding blade spring 5 outers after assembling, and eccentric hoop 2 is 1mm for the degree of eccentricity in live axle axle center.
Embodiment 2:
Use 6 slide plates.6 chutes are set rotor 1 surrounding is equidistant, 6 slide plates 3 and sliding blade spring 5 are installed in chute; The degree of eccentricity of eccentric hoop 2 is 2mm; Other component are installed and technical specifications, all with embodiment 1.
Embodiment 3:
Use 8 slide plates.8 chutes are set rotor 1 surrounding is equidistant, 8 slide plates 3 and sliding blade spring 5 are installed in chute; The degree of eccentricity of eccentric hoop 2 is 3mm; Other component are installed and technical specifications, all with embodiment 1.
Operation mechanism of the present invention is: when rotor 1 is during by the live axle driven rotary of high pressure oil pump, slide plate 3 is thrown out of by the effect of centrifugal force, is tightly fitted on the internal chamber wall of eccentric hoop 2.And because rotor 1 is installed in the bias of eccentric hoop 2 inner chambers, slide plate 3 slides along the groove on rotor 1, the descending variation of cavity volume between two slide plates 3, the diesel oil sucking at low pressure inlet place is compressed to high-pressure outlet place, diesel oil pressure is increased rapidly, to meet the needs of high-pressure service pump oil-feed; When low-speed running, sliding blade spring 5 promotes slide plate 3 and moves, and has compensated not enough centrifugal force, to meet the lowspeed pump oil mass of oil transfer pump.
