Abstract
The utility model relates to a hydraulic servo device, comprising an oil tank, an electromagnetic clutch type hydraulic pump, a one way valve, a flow controller, electromagnetic change valves. The electromagnetic change valves are connected in series through an oil tube, and are connected with the oil tank through the oil return pipeline. A power accumulator and an electric control liquid pressure gauge are respectively arranged between the one way valve and the flow controller in a shunt way, and the electromagnetic change valve is connected with the two way cylinder through an oil tube. As the structure is adopted, the electromagnetic clutch type hydraulic pump can be changed into the batch operation, which can saves a plurality of energy, and reduces the wear of the machine; the flow controller can be available to adjust the energy of the speed and the dynamics of the cylinder according to the requirement of the operation.
Description
Technical field
The utility model relates to a kind of hydraulic servo device.
Background technique
The work that present power source does not stop drives oil hydraulic pump, produce hydraulic power realization work, in working in the past, when the work that oil hydraulic pump does not stop produces hydraulic coupling greater than demand, come balance work by relief valve loss energy, waste a large amount of power sources like this, and increased wear and tear in machines.And the hydraulic jack operating rate is single now, does not have accumulator, can't change as the case may be.
The model utility content
The utility model purpose is to provide a kind of hydraulic servo device of energy-conservation, can regulate hydraulic machinery operating rate.
To achieve these goals, the utility model adopts following technological scheme: this device is gone here and there dress by fuel tank, electromagnetic clutch type oil hydraulic pump, one-way valve, flow dontroller, solenoid directional control valve successively by oil pipe, is connected with fuel tank by oil returning tube then; Accumulator and electric-controlled hydraulic table are installed between one-way valve and flow dontroller successively along separate routes; Described solenoid directional control valve links to each other with two-way cylinder by oil pipe.
The output oil pipe that is connected with described electromagnetic clutch type oil hydraulic pump is a high pressure pipe line.
Described accumulator is one or more.
After having adopted this structure, the electromagnetic clutch type oil hydraulic pump changes service intermittent into, saves a large amount of energy, and has reduced mechanical wear; The energy of the size of the speed of needs oil cylinder speed, dynamics when flow dontroller can be used for adjusting according to work.
Description of drawings
Fig. 1 is a schematic representation of the present utility model.
Embodiment
Embodiment: a kind of hydraulic servo device as shown in Figure 1, this device is gone here and there dress by fuel tank 2, electromagnetic clutch type oil hydraulic pump 1, one-way valve 3, flow dontroller 6, solenoid directional control valve 7 successively by oil pipe, is connected with fuel tank 2 by oil returning tube then; Accumulator 4 and electric-controlled hydraulic table 5 are installed between one-way valve 3 and flow dontroller 6 successively along separate routes; Described solenoid directional control valve 7 links to each other with two-way cylinder 11 by oil pipe.
The output oil pipe 9 that is connected with described electromagnetic clutch type oil hydraulic pump 1 is high pressure pipe line.
Accumulator 4 is one or more, and present embodiment adopts two accumulators 4.
Electromagnetic clutch type oil hydraulic pump 1 is to be combined by an electromagnet and a hydraulic-pressure pump, its work is to supply with by the power of motor output, its work requirements is the pressure demand according to accumulator 4, monitor by electric-controlled hydraulic table 5, when being lower than the hydraulic energy demand, electric-controlled hydraulic table 5 can be opened relay switch automatically, send power supply to make its work for electromagnetic clutch type oil hydraulic pump 1.
One-way valve 3 is supplied with accumulator 4 by the high-pressure and hydraulic oil of electromagnetic clutch type oil hydraulic pump 1 output through one-way valve 3, and its effect mainly is that anti-non-return drainage is pressed oil, alleviates the working pressure of electromagnetic clutch type oil hydraulic pump 1.
Fuel tank 2 is a stores hydraulic pressure oil.
Accumulator 4 predominant uses are stores hydraulic pressure energy, and enough hydraulic energies are arranged during with work.Its Stored Value is decided according to purposes.
Electric-controlled hydraulic table 5 is that a hydralic pressure gauge and an electrically switchable grating combine, and main effect is the storage volume that detects hydraulic pressure, when reaching reference value, disconnects the electromagnetism power supply of electromagnetic clutch type oil hydraulic pump 1; When being lower than reference value, connect the energy that power supply remains accumulator 4, enough energy are arranged during in order to work.
Flow dontroller 6 is energy of size of speed, the dynamics of needs oil cylinder speed when being used for adjusting according to work.
Solenoid directional control valve 7, it opens the hydraulic oil of accumulator 4 automatically after connecting power supply when needed, supplies with oil cylinder, its work full automation.
Flowline 8 is high-voltage tubes, and its diameter is to decide according to different purposes.
The diameter of oil returning tube 10 also is to decide according to different purposes.
This hydraulic servo device can be widely used in direction audiphone, the hydraulic system of crane locomotive, automobile chassis system automatic lifting, the spacious automatic telescopic system of paulin of car of automobile, and other hydraulic work systems.
