Description
Technical field
This utility model relates to pump class technical field, particularly relates to a kind of have high pressure conduction hole
Plunger displacement pump.
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 column
Plug 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 rotates
One turn, plunger pumps once, moves downward oil suction, and move upward oil extraction.Pump
The fluid volume that 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, with 1 song
Axle is by connecting rod slider or is pushed directly on plunger by eccentric shaft and moves reciprocatingly, it is achieved inhales, arrange
The hydraulic pump of liquid.They the most all use valve type flow distribution apparatus, and are mostly dosing pump.
Emulsion pump in coal mine hydraulic supporting system is typically all horizontal plunger pump.
3, axial plunger pump: axial plunger pump is piston or the vibration-direction of plunger and pump
The plunger displacement pump that body central shaft is parallel.Axial plunger pump utilizes the plunger parallel with power transmission shaft at post
Move back and forth what produced volume change was operated in consent.Due to plunger and plunger
Hole is all circular pieces, adds the class fit that can reach the highest man-hour, therefore volumetric efficiency
High.
4, d-axis swash plate plunger pump: d-axis swash plate plunger pump be divided into forced feed type and from
Two kinds of oil suction type.Forced feed type hydraulic pump is mostly the fuel tank using and having air pressure, by air pressure
The hydraulic oil container of fuel feeding, after starting machine every time, it is necessary to waits hydraulic pressure stain case to reach to use
After air pressure, machinery could be operated.Machine, meeting is just started during such as the air pressure deficiency of hydraulic oil container
Causing with piston shoes in hydraulic pump is pulled phenomenon, goes out to cause backhaul plate and pressing plate in the pump housing
Heel and toe wear.
5, radial plunger pump: radial plunger pump can be divided into Flat valve and the big class of axle flow two.Valve
There is the shortcomings such as fault rate is high, efficiency is low in flow distribution radial plunger pump.
6, hydraulic planger pump: hydraulic planger pump, by the hydraulic oil container of gas-pressurized, is opening every time
After movement machine, it is necessary to after waiting hydraulic oil container to reach to use air pressure, machinery could be operated.
Plunger in plunger displacement pump is during realizing oil suction oil extraction at present, due to Oil shocking
On the front end face of plunger, cavitation can be produced, reduce the service life of plunger.
