Accompanying drawing explanation
Fig. 1 is the structural representation of the better embodiment of the utility model hydraulic couplers hydraulic adjustment device.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described further:
Refer to Fig. 1, the utility model relates to a kind of hydraulic couplers hydraulic adjustment device, and its better embodiment comprises oil pump, motor, pressure transducer, frequency variator, controller, electric control valve 8 and five adjustable valves 6.
The filler opening of this oil pump is communicated with the oil outlet of the fuel tank of hydraulic couplers by main oil transport pipeline, the oil outlet of this oil pump is communicated with the working oil oil cooler of hydraulic couplers and the filler opening of lubricant oil oil cooler by oil transport pipeline, the oil outlet of this oil pump is also communicated with the filler opening of this fuel tank by main oil returning tube, the oil outlet of this working oil oil cooler and lubricant oil oil cooler is communicated with respectively the filler opening of this fuel tank by oil returning tube.Oil returning tube between oil pump and fuel tank is provided with electric control valve 8.Oil transport pipeline and the main oil transport pipeline between fuel tank and oil pump between oil transport pipeline between oil returning tube between oil returning tube between working oil oil cooler and fuel tank, lubricant oil oil cooler and fuel tank, working oil oil cooler and oil pump, lubricant oil oil cooler and oil pump are respectively established an adjustable valve 6.The output shaft of motor is by coupling, and controller is electrically connected this pressure transducer, electric control valve 8, this motor and frequency variator.
Oil pump is got oil by main oil transport pipeline from fuel tank, oil pump divides two-way to be delivered to respectively working oil oil cooler and lubricant oil oil cooler oily supercharging, each oil returning tube is for returning to remaining oil the filler opening of oil pump, with the output oil to fuel tank, lower the temperature, main oil returning tube returns to the excess oil after supercharging to fuel tank.So, can make hydraulic couplers move more stability and safety.
This pressure transducer is for detection of the pressure of the oil outlet of oil pump, and generates corresponding force value.This controller is compared this force value and predetermined threshold value, when force value is during lower than predetermined threshold value, starts oil pump, and by frequency variator, improves constantly the rotating speed of motor and oil pump, until force value equals predetermined threshold value by drive motor.When force value is during higher than predetermined threshold value, by motor, reduce the rotating speed of oil pump, until force value equals predetermined threshold value.This can make the pressure of the oil outlet of oil pump remain on certain secure threshold, improves oil circuit stability and Security.
Staff can show by working oil and the Lubricating Oil end finger of observing on hydraulic couplers, by regulating the aperture of above-mentioned each adjustable valve, makes it meet the pressure range of the normal work of hydraulic couplers.
