Abstract
The utility model provides an energy-saving hydraulic station which comprises an oil tank, a plunger pump and a working machine. The oil tank is connected with 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 accumulator is additionally arranged between the plunger pump and the working machine. The energy-saving hydraulic station has the advantages of low failure rate, low loss and small pressure fluctuation, and can guarantee normal and stable production.
Description
Technical field
The utility model relates to a kind of energy-conserving hydraulic station, belongs 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, mechanical energy is converted into the pressure energy of hydraulic station, hydraulic oil has realized direction, pressure, Flow-rate adjustment by 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 machinery actings.But this hydraulic station exists some defectives, shows that rate of fault height, oil temperature rise 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 prior art, the utility model provides a kind of energy-saving hydraulic station, comprise fuel tank, plunger pump, working machine, described fuel tank is connected in described plunger pump, described plunger pump is connected with described working machine, described working machine is connected with described fuel tank, it is characterized in that: increased an energy storage apparatus between described plunger pump and described working machine.
Described energy storage apparatus is the gravity type accumulator, and the piston of described gravity type accumulator is a cylindrical shape.
The utility model 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%
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Description of drawings: 1, fuel tank 2, plunger pump 3, working machine 4, gravity type accumulator
Embodiment
For above technical purpose being described better, the existing the technical solution of the utility model that describes in detail in conjunction with the accompanying drawings.
The utility model 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, described fuel tank (1) is connected in described plunger pump (2), described plunger pump (2) is connected with described working machine (3), and described working machine (3) is connected with described fuel tank (1).Wherein, described fuel tank (1) is shaped as rectangle or circle for storing and reclaim the container of hydraulic oil.Described plunger pump (2) is generally the high pressure one-shot pump.Described working machine (3) is kept the equipment of work for needing by continuing high pressure.The effect of described 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.Increased an energy storage apparatus in the utility model between described plunger pump (2) and described working machine (3), 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 utility model 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 entered next circulation.
Claims (2)
1. energy-saving hydraulic station, comprise fuel tank, plunger pump, working machine, described fuel tank is connected in described plunger pump, described plunger pump is connected with described working machine, described working machine is connected with described fuel tank, it is characterized in that: increased an energy storage apparatus between described plunger pump and described working machine.
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 described gravity type accumulator is a cylindrical shape.
