Problems solved by technology
When the hydraulic power is applied to the hook or excavator, since the equipment does not continuously work externally when it is working, its output power is intermittently output, so the continuous hydraulic power output by its hydraulic power pump cannot be used efficiently. When the hook machine or excavator does work externally, when the hook machine stops or does not perform work, the hydraulic pressure continuously output can only do useless work, and finally returns to the fuel tank, so the high hydraulic kinetic energy generated by the hydraulic power pump cannot be efficiently used

Embodiment Construction
[0016] The specific implementation manners of the present invention will be further described below with reference to the accompanying drawings.
[0017] Such as figure 1 and figure 2 As shown, a high-efficiency hydraulic power device includes an oil pump body 1 for providing high-pressure hydraulic oil, a storage piston cavity 2 for storing hydraulic oil, and a hydraulic oil work output port 3. The oil pump The body 1 and the hydraulic oil working output port 3 are connected to the storage piston cavity 2 through an oil passage 4 respectively. The storage piston chamber 2 includes a storage chamber 21, and a movable piston body 22 is provided with a plug in the storage chamber 21. The moving limit buffer device 5 is arranged in abutment.
[0018] Such as figure 1 and figure 2 As shown, above the side wall of the storage chamber 21 is equipped with an oil discharge valve body 23, when the piston body 22 moves to its highest point, the oil discharge valve body 23 opens, ...

The invention discloses an efficient hydraulic power unit. The efficient hydraulic power unit comprises an oil pump body used for providing high-pressure hydraulic oil, a storage piston cavity used for storing hydraulic oil and a hydraulic oil work output end. The oil pump body and the hydraulic oil work output end communicate with the storage piston cavity through two oil ways correspondingly. According to the efficient hydraulic power unit, a hydraulic power pump can be effectively used for outputting high hydraulic kinetic energy; moreover the efficient hydraulic power unit is simple and ingenious in structure and high in operability.
Description
technical field [0001] The invention relates to the field of hydraulic power equipment and accessories, more specifically, a high-efficiency hydraulic power device. Background technique [0002] The hydraulic power pump station is a pump station that provides hydraulic power in the hydraulic system. It generally uses hydraulic oil that meets the requirements of the hydraulic system as the medium. pump, etc.) to send out the medium that meets the required flow and pressure for use in the hydraulic system. The medium of the hydraulic power pump station is generally recycled, so it is equipped with a cooling system, a filtration system, a pressure regulation system, a safety guarantee system, a flow regulation system, a pressure and temperature indication, a valve control and a medium (oil) storage tank, and some It is also equipped with an energy storage device. When working, the hydraulic pressure from the hydraulic pump driven by the motor is reduced to the working pressur...
