Description
Technical field
This utility model relates to pump class technical field, particularly relates to a kind of storage bits type pump housing.
Background technology
Plunger displacement pump is an important device of hydraulic system.It relies on plunger reciprocal in the pump housing
Motion, makes the volume of seal operation cavity volume change and realizes oil suction, force feed.Plunger displacement pump
There is the advantages such as rated pressure height, compact conformation, efficiency height and Flow-rate adjustment convenience, by extensively
General high pressure, big flow and the flow of being applied to needs the occasion of regulation, such as hydraulic press, engineering
In machinery and boats and ships.Plunger displacement pump is generally divided into single plunger pump, horizontal plunger pump, axial plunger
Pump and radial plunger pump.1, single plunger pump: single plunger pump structure composition mainly have eccentric,
Plunger, spring, the pump housing, two check valves.Sealed volume is formed between plunger and pump housing hole.
Eccentric rotation is gone around, and plunger pumps once, moves downward oil suction, upwards transports
Dynamic oil extraction.The fluid volume that pump every revolution is discharged is referred to as discharge capacity, discharge capacity and pump structure
Relating to parameters.2, horizontal plunger pump: horizontal plunger pump is to be installed side by side by several plungers, uses
1 bent axle is by connecting rod slider or is pushed directly on plunger by eccentric shaft and moves reciprocatingly, it is achieved
Suction, the hydraulic pump of discharging liquid.They the most all use valve type flow distribution apparatus, and are mostly fixed
Amount pump.Emulsion pump in coal mine hydraulic supporting system is typically all horizontal plunger pump.3, axle
To plunger displacement pump: axial plunger pump is vibration-direction and the pump housing central shaft of piston or plunger
Parallel plunger displacement pump.Axial plunger pump utilizes the plunger parallel with power transmission shaft past in plunger hole
Multiple motion produced volume change is operated.Owing to plunger and plunger hole are all round
Shape part, adds the class fit that can reach the highest man-hour, and therefore volumetric efficiency is high.4, straight
Axle swash plate plunger pump: d-axis swash plate plunger pump is divided into forced feed type and self-priming oil type two
Kind.Forced feed type hydraulic pump is mostly the fuel tank using and having air pressure, by the liquid of gas-pressurized
Force feed case, after starting machine every time, it is necessary to after waiting hydraulic pressure stain case to reach to use air pressure,
Machinery could be operated.Machine is just started during such as the air pressure deficiency of hydraulic oil container, can be to hydraulic pump
In cause with piston shoes and pull phenomenon, go out to cause the improper of backhaul plate and pressing plate in the pump housing
Abrasion.5, radial plunger pump: radial plunger pump can be divided into Flat valve and the big class of axle flow two.
There is the shortcomings such as fault rate is high, efficiency is low in Flat valve radial plunger pump.6, hydraulic planger pump:
Hydraulic planger pump is by the hydraulic oil container of gas-pressurized, after starting machine, it is necessary to wait liquid every time
After force feed case reaches to use air pressure, machinery could be operated.
Plunger in plunger displacement pump is during realizing oil suction oil extraction at present, in hydraulic oil liquid
Plunger hole in the pump housing can be worn and torn by molecule, reduces the service life of the pump housing.
Utility model content
This utility model is in order to overcome deficiency of the prior art, it is provided that a kind of storage bits type pump
Body.
This utility model is to be achieved through the following technical solutions:
A kind of storage bits type pump housing, including the pump housing, is provided with pump cover in the side of the pump housing, described
Offer the first plunger channel and the second plunger channel in the pump housing, in described pump cover, offer
One plunger hole and the second plunger hole, offer some on the inwall of described first plunger channel
The semicircle nail collection slot of the first of individual hoop, offers on the inwall of described second plunger channel
Several second semicircle nail collection slots, the described first semicircle nail collection slot and the second semicircle storage
The quantity of bits groove is identical, and size is identical.
As optimal technical scheme of the present utility model, the described first semicircle nail collection slot and the
The quantity of two semicircle nail collection slots is even number.
As optimal technical scheme of the present utility model, described first plunger hole and the first plunger
Passage communicates, and described second plunger hole and the second plunger channel communicate.
As optimal technical scheme of the present utility model, described first plunger channel and the second post
The size of plug passage is identical, and the size of described first plunger hole and the second plunger hole is identical.
Compared with prior art, the beneficial effects of the utility model are: this utility model leads to
Cross in the first plunger channel and the second plunger channel, offer the first semicircle nail collection slot respectively
With the second semicircle nail collection slot, it is possible to effectively the molecule in hydraulic oil liquid is stored
Come, prevent molecule from the inwall of the first plunger channel and the second plunger channel being worn and torn,
Improve its service life.
Accompanying drawing explanation
