Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic power units, and more particularly to a hydraulic power unit that is easy to maintain. Background Art

[0002] The hydraulic power unit (HPU) serves as an oil supply device, connected to several hydraulic cylinders via an external piping system to control the movement of multiple valves. The oil tank, oil pump, and accumulator form an independent, sealed power oil source system. The oil station can be equipped with a PLC control system, which controls all internal hydraulic functions and generates signals for communication with the control center (DCS). Control components, such as the hydraulic servo valve, are directly mounted on the hydraulic cylinders, through which high-pressure oil is pumped into and released from the cylinders. Under normal conditions, the oil pump supplies oil to the system, automatically maintaining the rated system pressure and locking the control valve to ensure the valve is locked in any position. In the operating state, the hydraulic actuator is controlled by a solenoid valve. System command signals activate the solenoid valve, controlling the oil pressure and the release of energy from the accumulator. This in turn controls the cylinder spool valve, which is driven by a mechanical transmission mechanism to implement rapid closing, normal opening and closing, and test control.

[0003] The control components, power components and oil pipes of the existing hydraulic power unit are exposed on the oil tank and are easily damaged when impacted by external forces, which increases maintenance costs and is not conducive to the continuous and efficient operation of the hydraulic power unit.

[0006] Preferably, the side bracket is a square structure made of square stainless steel pipe.

[0007] Preferably, the control box is mounted on a side bracket.

[0008] Preferably, the protective plate is made of a square stainless steel tube.

[0009] Preferably, there are two thickened cover plates on either side of the fuel tank.

[0010] Preferably, the thickened cover plate is a circular structure.

[0011] Preferably, the support legs are made of U-shaped stainless steel.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. By setting up side brackets, support rods and protective plates, the sides and top of the hydraulic power unit that are easily damaged by external forces can be protected. By setting up support legs and thickened cover plates, the rest of the oil tank can be protected, thereby providing better protection.

[0014] 2. By setting the side brackets, protective plates and supporting legs to be made of various angle steel materials, the structure can be easily manufactured while achieving the minimum protection effect, and has better practicality. BRIEF DESCRIPTION OF THE DRAWINGS
