Description
Technical field
The present invention relates to engineering and farm machinery fuel delivery pump, is the multidirectional fuel delivery pump of a kind of V-type and using method thereof.
Background technique
At present, in engineering and farm machinery fuel delivery pump field, the kind of pump presses in Way out and is divided into two classes, and a class imports and exports in horizontal direction, and two classes are that import and export are vertical in 90 degree upward with substantially horizontal.Its working principle is: the pump housing is by while driven by motor vane rotary, and the blades on impeller rotates, thus makes to produce pressure difference in cavity, and liquid flows into out oil-in chamber from oil-feed chamber, thus reaches the object of conveying liquid.Importing and exporting in above-mentioned two series products is substantially horizontal, and the pump housing is easily processed, and relief valve can be housed; And import and export are Vertical direction, the pump housing, then because reasons in structure cannot arrange relief valve, often causes motor rotation blockage because of unexpected cut out nozzle during transfer pump work, and motor damage.These two kinds of fuel delivery pumps adopt moulds different separately and frock clamping to produce, and product-specific investments is large, and manufacture cost is high; Supporting the use at product, higher for requirements of installation space.
Summary of the invention
For overcoming above-mentioned deficiency, the object of the invention is to provide the multidirectional fuel delivery pump of a kind of V-type and using method thereof to related domain, make it solve oil plant in existing like product and import and export more difficult any 360 degree of revolutions separately according to actual needs, and the similar Vertical direction import and export pump housing lacks the technical problem of relief valve setting.Its objective is and to be achieved through the following technical solutions.
The multidirectional fuel delivery pump of a kind of V-type, this fuel delivery pump comprises pump housing assembly and motor, described pump housing assembly comprises fuel inlet neck, pressing plate, filler opening, clamping bolt, oil outlet, fuel discharge port, relief valve, wheel member, the pump housing, cover plate, oil sealing, the Motor Shaft of described motor is connected with the wheel member in the pump housing, the pump housing place of stretching into of Motor Shaft is provided with oil sealing, and the wheel member outer side surface of the pump housing is provided with cover plate; The pump housing is provided with filler opening and oil outlet, and the filler opening of the pump housing and oil outlet are respectively equipped with fuel inlet neck and fuel discharge port; Its structural design main points are that the axis of described filler opening and oil outlet is crossing respectively with relief valve axis, the angle intersected is less than 90 degree respectively, i.e. filler opening and the V-shaped layout of oil outlet, fuel inlet neck, fuel discharge port are less than 90 degree at the axis of pump housing exposed parts respectively with the axis angle of cooperation place in the pump housing; Filler opening, the oil outlet surface of contact of fuel inlet neck, fuel discharge port and the pump housing are respectively equipped with seal ring, and by pressing plate, fuel inlet neck and fuel discharge port are connected on the pump housing, fuel inlet neck, fuel discharge port respectively with respective oil inlet and outlet axis for freely returning three-sixth turn in axle center.The V-type design of filler opening and oil outlet in the above-mentioned pump housing, the angle of filler opening, oil outlet axis and relief valve axis designs, and fuel inlet neck, fuel discharge port axis and the design of cooperation place axis in the pump housing, make fuel inlet neck, fuel discharge port respectively with the plane of filler opening, oil outlet at an angle, thus be convenient to fuel inlet neck, fuel discharge port freely turn round be adjusted to various be convenient to that fuel feed tube connects into and out of angle.
The angle that the axis of described filler opening and oil outlet is crossing with relief valve axis is 45 degree of angles respectively, and fuel inlet neck, fuel discharge port are 45 degree of angles at the axis of pump housing exposed parts and the axis of cooperation place in the pump housing respectively.45 degree of angle structures of above-mentioned correspondence, for fuel inlet neck, fuel discharge port freely turn round regulate after, the best angle be connected with the fuel feed tube under respective different amount designs.
Described fuel inlet neck, fuel discharge port are fixed on the pump housing by pressing plate, clamping bolt respectively; Unclamp clamping bolt, fuel inlet neck, fuel discharge port freely turn round respectively, tighten clamping bolt after forwarding the angle of needs to, and fuel inlet neck, fuel discharge port are compressed by pressing plate respectively and be in stationary state.
The substantially horizontal dimension D of described filler opening and oil outlet is greater than the diameter dimension d of overflow valve opening.Said structure is conducive to the processing of overflow valve opening, and the adjustment of overflow valve opening place oil spilling pressure.
Described overflow valve opening is arranged at the pump housing chamber between filler opening and oil outlet, and overflow valve opening place is provided with relief valve.The structure of above-mentioned relief valve and setting make this fuel delivery pump operationally, can not cause motor rotation blockage, prevent the generation of motor damage situation because of unexpected closedown nozzle.
The relief valve of described overflow valve opening comprises valve plug, spring, valve seals, valve plug is in " T " font, namely the valve plug head cap end of filler opening side is provided with valve seals, valve seals is positioned at the aperture place of overflow valve opening, the end face of the valve plug the other end is provided with spring bayonet socket, one end of spring and the spring bayonet socket of valve plug fasten, and the other end is butted on the overflow valve opening place of oil outlet side mutually.When oil plant, in the process being entered oil outlet by filler opening, oil spilling situation occurs, the overflow valve opening at relief valve place is opened, and oil spilling flows back into filler opening by oil outlet.Meanwhile, above-mentioned is a kind of concrete structure of relief valve, and relief valve also can adopt the existing similar overflow being applicable to this fuel delivery pump.As increased stop nut at relief valve, concrete structure is as follows: the relief valve of described overflow valve opening comprises valve plug, spring, valve seals and stop nut, valve plug is in " T " font, valve plug is provided with outside thread, namely the valve plug head cap end of filler opening side is provided with valve seals, valve seals is positioned at the aperture place of overflow valve opening, and the other end of valve plug is provided with stop nut, and spring is butted on the overflow valve opening place of stop nut and oil outlet side mutually.Thus rotary spacing nut, the i.e. elastic force of adjustable springs.
The present invention assembles simply, easy to maintenance, greatly reduces the cost of investment of product compared with original technology, and product versatility is stronger, solve hydraulic fluid port upward oil plant pump a historic difficult problem for relief valve can not be housed; Meanwhile, it is low to requirements of installation space, and joint is optionally rotated, meets the difference needs under various environment, reduces assembly cost.It is suitable as fuel delivery pump and uses, ex hoc genus anne the architecture advances of product.
