Description
Technical field
It the utility model is related to gear pump technical field, more particularly to a kind of durable gear pump.
Background technology
Gear pump is to convey liquid by the swept volume change and movement that are formed between pumping cylinder and meshing gear or make
Supercharging drum pump, form two closing spaces by two gears, the pump housing and front and rear covers, when pinion rotation, be out of gear
The volume in the space of side becomes big from small, forms vacuum, draws liquid into, the volume in the space of gear engagement side from diminishing greatly, and
Liquid is squeezed into pipeline.Both sides are respectively pumping cavity and oil sucting cavity in gear pump, the pressure of two chambers be it is unbalanced, in addition
Pumping cavity is because tooth top leaks, and its pressure is successively decreases, and neither counterpressure acts on generation radial direction unbalanced pressure on gear and axle,
Oil pressure is higher, and the power is bigger, accelerates bearing wear, makes bending shaft, increases tooth top and is worn with axis hole, influences bearing service life.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of durable gear pump, to solve deficiency of the prior art.
In order to achieve the above object, the purpose of this utility model is achieved through the following technical solutions：
A kind of durable gear pump, including the pump housing be provided, the pump housing include housing, the first pad, gear train, gear shaft,
Covering and the second pad, the housing is interior to be provided with oil pocket, is placed in the oil pocket to the gear train intermeshing, the screening
Cover and be provided with axis hole, for the gear train on the gear shaft, the gear shaft connects external motor, institute through the axis hole
State and pressure-regulating valve is provided between gear shaft, the housing, first pad, the covering and second pad connect successively
Connect, the housing is provided with oil-out, and the oil-out of the housing is connected with the valve with ball elbow.
Above-mentioned durable gear pump, wherein, locating ring is provided between the covering and second pad, the gear shaft
The end of one of them connects the locating ring.
Above-mentioned durable gear pump, wherein, the pump housing is made of stainless steel.
Compared with the prior art, the beneficial effects of the utility model are：
Simple and compact for structure, pressure-regulating valve can extenuate radial direction unbalanced pressure phenomenon, stainless steel to a certain extent
Corrosion resistance and good, application field is extensive, and working service is convenient.
Brief description of the drawings
Form a part of accompanying drawing of the present utility model to be used for providing further understanding to of the present utility model, this practicality is new
The schematic description and description of type is used to explain the utility model, does not form to improper restriction of the present utility model.
In accompanying drawing：
Fig. 1 shows the structural representation of the durable gear pump of the utility model.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out

It should be noted that in the case where not conflicting, the feature in embodiment and embodiment in the utility model can
To be mutually combined.
With reference to shown in figure 1, the durable gear pump of the utility model includes the pump housing, and the pump housing includes housing 1, the first pad 2, gear
Group 3, gear shaft 4, the pad 6 of covering 5 and second, housing 1 is interior to be provided with oil pocket, is placed in oil pocket to the intermeshing of gear train 3, hides
Lid 5 is provided with axis hole, and for gear train 3 on gear shaft 4, gear shaft 4 connects external motor through axis hole, is set between gear shaft 4
There is pressure-regulating valve 7, housing 1, the first pad 2, the pad 6 of covering 5 and second are sequentially connected, and housing 1 is provided with oil-out, housing
1 oil-out is connected with the valve 8 with ball elbow.In the technical program, it is fixed to be provided between the pad 6 of covering 5 and second
The end connection locating ring 9 of position one of ring 9, gear shaft 4, the pump housing is made of stainless steel, and stainless gear pump can convey
Beverage and corrosive liquid.
From above-described embodiment as can be seen that advantage of the present utility model is：
Simple and compact for structure, pressure-regulating valve can extenuate radial direction unbalanced pressure phenomenon, stainless steel to a certain extent
Corrosion resistance and good, application field is extensive, and working service is convenient.
Specific embodiment of the utility model is described in detail above, but the utility model is not restricted to the above
The specific embodiment of description, it is intended only as example.To those skilled in the art, any equivalent modifications and substitute also all
Among category of the present utility model.Therefore, the impartial conversion made in the case where not departing from spirit and scope of the present utility model
And modification, it should all cover in the scope of the utility model.
