Abstract
The utility model relates to an impulse wave gear pump which comprises a pump body, a front cover and a rear cover. The pump body is internally provided two gears engaged with each other. Side plates are respectively arranged between the gears and the front cover and between the gears and the rear cover. The front and rear covers are provided with impulse holes matched with the side plates. The impulse wave gear pump provided by the utility model has the beneficial effects that the impulse wave gear pump is reasonable in structure and good in effect; the volume of an impulse pump can be reduced; as the impulse pump compensates the fit clearance between the gears and the side plates automatically by an extrusion force, and the front pressure of the side plates is smaller or equal to the back thrust, the efficiency of the pump reaches above 97%.
Description
Technical field
The utility model relates to a kind of gear pump, especially a kind of Pulse wave gear pump.
Background technique
Existing gear pump often build is larger, but efficient is not high.
Summary of the invention
The utility model will solve the shortcoming of above-mentioned prior art, and the Pulse wave that a kind of volume is little, efficient is high gear pump is provided.
The utility model solves the technological scheme that its technical problem adopts: this Pulse wave gear pump, comprise the pump housing, protecgulum and bonnet, be provided with two engaged gears in the pump housing, be equipped with a side plate between gear and protecgulum, the bonnet, protecgulum, bonnet are provided with the pulse hole of matching with side plate.
As preferably, described side plate is eccentric, is divided into zone of high pressure and low pressure area, and wherein the cross section, zone of high pressure is less than low pressure area.
As preferably, described pulse hole open with the corresponding part, zone of high pressure of side plate.
As preferably, be provided with protection copper packing and seal ring between described side plate and protecgulum, the bonnet.
The effect that the utility model is useful is: the utility model is rational in infrastructure, effective, the volume of Pulse wave pump can reduce, because pulse pump itself is the matching gap by extruding force auto-compensation gear and side plate, the positive pressure of side plate is less than or equal to back side thrust, so the efficient of pump reaches more than 97%.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the plan view of side plate;
Fig. 3 is the plan view of protecgulum;
Fig. 4 is the plan view of bonnet;
Description of reference numerals: the pump housing 1, protecgulum 2, bonnet 3, gear 4, side plate 5, protection copper packing 6, seal ring 7, zone of high pressure 8, low pressure area 9, pulse hole 10.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
Embodiment: such as Fig. 1, this Pulse wave gear pump comprises the pump housing 1, protecgulum 2 and bonnet 3, is provided with two engaged gears 4 in the pump housing 1, be equipped with a side plate 5 between gear 4 and protecgulum 2, the bonnet 3, protecgulum 2, bonnet 3 are provided with the pulse hole 10 of matching with side plate 5.Described side plate 5 off-centre are divided into zone of high pressure 8 and low pressure area 9, and wherein 8 cross sections, zone of high pressure are less than low pressure area 9.Described pulse hole 10 open with 8 corresponding parts, zone of high pressure of side plate 5.Be provided with protection copper packing 6 and seal ring 7 between described side plate 5 and protecgulum 2, the bonnet 3.
Because side plate 5 is eccentric, automatic adjustable balance when producing pressure, according to the needs auto-compensation impact of pressure, side plate 5 extruding are once during gear 4 revolutions one tooth, gear 4 makes surge pressure greater than gear cross section pressure with the frictional force of side plate 5, like this with regard to continuous generation Pulse wave.The impulse force of Pulse wave produces pressure in the cross section of cylinder, oil pipe, oil sealing are not produced impulsive force, because oil sealing, oil pipe are the inclined-planes.When testing, the stress reaction of Pulse wave hangs down 40%-50% than original pumping pressure.
In addition to the implementation, the utility model can also have other mode of executions.All employings are equal to the technological scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
