Abstract
The invention provides an energy-saving hydraulic station which comprises an oil tank, a plunger pump and a working machine, wherein the oil tank is connected to the plunger pump; the plunger pump is connected with the working machine; and the working machine is connected with the oil tank. The energy-saving hydraulic station is characterized in that an energy accumulation device is added between the plunger pump and the working machine. The hydraulic station has low fault rate, low loss consumption and small pressure oscillation, and the normal and stable production is ensured.
Description
Technical field
The present invention relates to a kind of energy-conserving hydraulic station, belong to the oil hydraulic pump field.
Background technique
The working principle that the lasting high pressure of general needs is kept the hydraulic station of work is: the driven by motor oil pump rotates; Pump is the oil suction fuel feeding from fuel tank; The pressure that mechanical energy is converted into hydraulic station can; Hydraulic oil has realized direction, pressure, Flow-rate adjustment through integrated package (or valve combination) after external pipeline and to the oil cylinder or oil motor of hydraulic machinery, thereby conversion, the size of strength and the speed of speed of control hydraulic motor direction promote various hydraulic machineries actings.But this hydraulic station exists some defectives, shows that rate of fault is high, the oil temperature rises soon, temperature is high, loss is big, and pressure surge is big, and is very big to normal steady production influence.
Summary of the invention
In order to overcome the defective that exists in the existing technology; The invention provides a kind of energy-saving hydraulic station; Comprise fuel tank, plunger pump, working machine, said fuel tank is connected in said plunger pump, and said plunger pump is connected with said working machine; Said working machine is connected with said fuel tank, it is characterized in that: between said plunger pump and said working machine, increased an energy storage apparatus.
Described energy storage apparatus is the gravity type accumulator, and the piston of said gravity type accumulator is a cylindrical shape.
The present invention is applicable to that various needs keep the auxiliary work of the working machine of work by continuing high pressure, compares with the plain edition hydraulic station:
1, rate of fault reduces by 70%
2, oil consumption reduces by 80%
3, maintenance cost reduces by 30%
4, manufacturing efficiency improves 30%

Embodiment
Above technical purpose combine accompanying drawing to specify technological scheme of the present invention in order to explain better at present.
The invention provides a kind of energy-saving hydraulic station; Comprise fuel tank (1), plunger pump (2), working machine (3), three-way valve and high pressure liquid casting die; Wherein the high pressure liquid casting die comprises oil pipe and valve; Said fuel tank (1) is connected in said plunger pump (2), and said plunger pump (2) is connected with said working machine (3), and said working machine (3) is connected with said fuel tank (1).Wherein, said fuel tank (1) is shaped as rectangle or circular for storing and reclaim the container of hydraulic oil.Said plunger pump (2) is generally the high pressure one-shot pump.Said working machine (3) is kept the equipment of work for needing by continuing high pressure.The effect of said three-way valve is the flow direction of control hydraulic oil, can automatically switch to different directions according to the pressure height with flow direction, realizes control automatically.Between said plunger pump (2) and said working machine (3), increased an energy storage apparatus among the present invention, this energy storage apparatus is gravity type accumulator (4), and its piston is a cylindrical shape.When compression pump pressure surpasses the working machine working pressure; Gravity type accumulator (4) with unnecessary energy storage within it; When working pressure was lower than setting value, the energy in the gravity type accumulator (4) began to discharge, and adds in the working machine (3) and keeps working pressure.
Working principle of the present invention is: when motor drives plunger pump (2) is worked; The pressure that plunger pump (2) produces is higher than the working pressure of working machine (3); The energy that this part pressure produces rises the piston of gravity type accumulator (4); The working pressure that makes working machine in the system (3) is maintained and can be not too high, and motor quits work when reaching setting value.
The piston that rises has certain potential energy, and when the working pressure of working machine (3) was lower than setting value, three-way valve was opened, and the potential energy of piston begins to discharge, and piston descends.After piston was reduced to minimum point, when whole system pressure was lower than setting pressure, motor began again to start, and got into next circulation.
Claims (2)
1. energy-saving hydraulic station; Comprise fuel tank, plunger pump, working machine; Said fuel tank is connected in said plunger pump; Said plunger pump is connected with said working machine, and said working machine is connected with said fuel tank, it is characterized in that: between said plunger pump and said working machine, increased an energy storage apparatus.
2. energy-saving hydraulic according to claim 1 station is characterized in that: described energy storage apparatus is the gravity type accumulator, and the piston of said gravity type accumulator is a cylindrical shape.
