Description
Technical field
The utility model belongs to hydraulic pump technical field more particularly to a kind of hydraulic gear pump pump cover.
Background technique
Hydraulic pump is the dynamical element of hydraulic system, is that oil is sucked from hydraulic oil container by engine or motor drive
Liquid forms pressure oil discharge, is sent to a kind of element of executive component.I.e. hydraulic pump is come in fact by the change of closed swept volume
It now inhales, press liquid, converts mechanical energy into hydraulic energy.
Hydraulic pump is broadly divided into gear pump, plunger pump, vane pump and four kinds of screw pump, and wherein gear pump structure is simply tight
It gathers, good manufacturability is insensitive to oil contamination, and reliable working performance is cheap, is widely used.But current gear
Pump still has several drawbacks, if radial force of the entry/exit oil liquid to gear acts on, after long-play occurs easily gear shaft curved
It is bent；At runtime, the confined space formed between two teeth can be such that oil liquid is sealed in the space for driving tooth and driven tooth, generate
Pocketed oil phenomenon, causes vibration and noise, influences system operation.Gear needs running check and maintenance in use, therefore
It needs often to dismantle and move pump cover.
Utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, provide a kind of hydraulic gear pump pump cover.
Pump cover provided by the utility model effectively reduce oil liquid to the radial impact force of gear, solve pocketed oil phenomenon, reduce
Noise and vibration, and sound construction, conveniently moving.
The technical solution adopted in the utility model is as follows:
A kind of hydraulic gear pump pump cover, including pump cover ontology, which is characterized in that the pump cover ontology be equipped with oil inlet,
Oil outlet and compensating groove, the oil inlet aperture are big compared with the oil outlet aperture；There are two the compensating grooves, is located at two gears
On the pump cover ontology at tangent part rear, two compensating grooves are respectively communicated with oil inlet and oil outlet；The pump cover body outer surface
Equipped with handle and reinforcing rib.
It further, further include the seal washer to match with pump cover ontology working face.
Further, the pump cover ontology is equipped with gasket mounting hole, sets the installation to match on the seal washer
Tooth.
Further, the seal washer is made of polypropylene material.
Further, the pump cover ontology is equipped with perforative peace turn hole, and the bolt hole is equipped with 6.6 bolts hole
Position is symmetrical two-by-two, and is evenly distributed on pump cover body edges, guarantees that pump cover ontology is steady secured with pump housing installation.
Further, the bolt hole and the reinforcing rib non-overlapping or intersect.
Further, the handle and pump cover ontology are the integral structure of one-piece casting.One-piece casting can guarantee handle
Fastness moves pump cover ontology in easy to disassemble, installation process, and guarantees to move the safety of process.
The beneficial effects of the utility model are:
1, the utility model designs oil inlet and oil outlet on pump cover ontology, and expands oil inlet aperture, reduces out
Hydraulic fluid port aperture, so that oil inlet aperture is big compared with oil outlet aperture.Oil inlet, oil outlet design make on pump cover oil liquid axially into
Oil pocket avoids the direct impact to gear radial direction；Expand oil inlet, reduces oil outlet, slow down and balance oil liquid to gear
Radial impact force.The radial force of gear is reduced, it is possible to prevente effectively from gear shaft bends, keeps pump housing operation more steady
Fixed, service life extends.
2, the utility model designs two compensating grooves, and is respectively communicated with oil inlet and oil outlet, when can effectively solve operation
Pocketed oil phenomenon caused by the confined space formed between two gears, while the vibration and noise generated by pocketed oil phenomenon is reduced,
Keep the operation of pump housing system more stable.
3, reinforcing rib and handle are set in pump cover body outer surface, increases pump cover voltage endurance capability and intensity, while reducing pump cover
The weight of ontology, it is convenient to move the pump cover pump housing in disassembly, installation process.
