Description

Energy-saving hydraulic station
Technical field
The utility model relates to a kind of hydraulic station, particularly a kind of energy-saving hydraulic station.
Background technique
The working principle of the general hydraulic station that need to continue high pressure maintenance work is: driven by motor oil hydraulic pump rotates, oil hydraulic pump is oil suction fuel feeding from fuel tank, mechanical energy is converted into the pressure energy of hydraulic station, hydraulic oil has been realized direction by integrated package, pressure, after Flow-rate adjustment through external pipeline and to the oil cylinder or oil motor of hydraulic machinery, thereby control the conversion of hydraulic motor direction, the size of strength and the speed of speed, promote various hydraulic machinery actings, but this hydraulic station exists some defects, show that rate of fault is high, oil temperature rises fast, temperature is high, loss is large, pressure surge is large, very large on normal steady production impact.
Model utility content
The purpose of this utility model is just to provide a kind of failure rate is low, loss little, saves job costs, the energy-saving hydraulic station of long service life.
To achieve these goals, the technical solution adopted in the utility model is such: energy-saving hydraulic of the present utility model station, comprise fuel tank, motor, oil hydraulic pump and control cabinet, driven by motor hydraulic pump works, the oil inlet pipe of oil hydraulic pump connects fuel tank, the oil outlet tube of oil hydraulic pump connects the hydraulic circuit of working machine, the hydraulic circuit oil return of working machine is to fuel tank, described motor is variable-frequency motor, the oil inlet pipe of described oil hydraulic pump is provided with one-way valve, the oil outlet tube of oil hydraulic pump is provided with pressure transducer, pressure transducer is connected with the control unit in control cabinet, between oil hydraulic pump and working machine, be also connected with energy storage apparatus.
As preferably, described fuel tank is provided with liquid level liquid thermometer, air-strainer and electric contact bimetallic thermometer.
As preferably, described energy storage apparatus is gravity type accumulator.
Compared with prior art, the utility model has the advantage of: the utility model is reasonable in design, on the oil inlet pipe of oil hydraulic pump, one-way valve is set, avoid hydraulic oil to reflux, pollute, on the oil outlet tube of oil hydraulic pump, pressure transducer is set, control the rotating speed of motor according to the pressure of oil hydraulic pump oil outlet tube and flow, avoid motor to drive oil hydraulic pump to rotate with rated speed always, produce unnecessary electric energy loss, save the job costs of hydraulic station, between oil hydraulic pump and working machine, be also connected with energy storage apparatus, in the time that compression pump pressure exceedes working machine working pressure, gravity type accumulator by unnecessary energy storage therein, when working pressure is during lower than setting value, energy in gravity type accumulator starts to discharge, add to maintenance work pressure in working machine, the working efficiency of hydraulic station and the working life of hydraulic station are improved.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
