The pump housing of hydraulic pump is usually to be bolted with pump cover, and annular seal groove is set on contact surface and installs sealing
Circle is sealed；In hydraulic pump operation, because oil liquid pressure to high pressure from rising in the low pressure short time, make the members such as the pump housing, pump cover
Part bears huge shock loading, easily causes the junction of the pump housing and lid to leak, influences the function of hydraulic pump.
Also because the shock loading of receiving is big, hydraulic pump is high to the resistance to pressure requirement of the pump housing and pump cover, in order to guarantee pump cover
Pressure-resistant performance, being commonly designed is the thickness for increasing pump cover, but increase thickness simply will use more materials and increase
Production cost can also make pump cover become heavy.
Utility model content
The purpose of this utility model is: in view of the above shortcomings of the prior art, provide it is a kind of structurally reasonable, it is light-weight, it is resistance to
Pressure property is strong, and sealing effect is good, antileakaging pump cover.
The technical solution adopted in the utility model is as follows:
A kind of hydraulic pump cover, including pump cover ontology, pump cover bearing hole, circular cavity region, entry/exit oilhole and bolt hole,
The entry/exit oilhole is set to circular cavity region upper and lower sides, which is characterized in that circular cavity region arranged on left and right sides set it is high/
Low pressure buffer area；The operative end surface of the pump cover ontology is smooth flat, and the sectional gland bush that shape matches is arranged；The pump
Lid body outer surface is equipped with ribs.
Further, high low pressure buffer area height 2.0 ~ 5.0mm low compared with operative end surface.
Further, the pump cover ontology is equipped with gasket mounting hole, and the sectional gland bush is equipped with corresponding peace
Toothing.There are three the gasket mounting holes into rounded projections arranged, convenient for the location and installation of sectional gland bush.
Further, the pump cover ontology is equipped with location hole, and the location hole is symmetrically set in pump cover body edges.Positioning
For installing locating piece, it is more accurate that setting location hole can guarantee that pump cover is installed with the pump housing in hole.
Further, the entry/exit oilhole opening is located in operative end surface, not be overlapped with high low pressure buffer area.
Further, corresponding entry/exit oilhole, bolt hole and location hole are additionally provided on the sectional gland bush.It is installing
When pump cover and the pump housing, bolt is installed and locating piece passes through the corresponding hole of gasket, guarantees that gasket firmly installs.
Further, the pump cover ontology is made of aluminium alloy.Pump cover intensity made of aluminium alloy is high, and corrosion resistance is strong,
It is light-weight, it is suitble to operation under a variety of environment.
The beneficial effects of the utility model are:
1, the pump cover of the utility model designs high low pressure buffer area in circular cavity region arranged on left and right sides, and oil is effectively relieved
The impact force that liquid generates pump cover and the pump housing, reduces the probability of hydraulic bump leakage.
2, the operative end surface of pump cover ontology is smooth flat, and the sectional gland bush that shape matches, profiled seal is arranged
Pad passes through the installation such as the installation bolt of pump cover, locating piece, installation knot by gasket mounting hole and corresponding installation tooth positioning
Structure is stablized, and big with pump cover contact area, sealing effect is good.
3, the pump cover body outer surface of the utility model is equipped with ribs, and design ribs is guaranteeing pump cover voltage endurance capability
It is effectively reduced the weight of pump cover simultaneously.
