[0019] figure 1 It is the schematic diagram of the circuit of the mobile hydraulic pump station.
[0020] Such as figure 1 As shown, the mobile hydraulic pump station 10 involved in the present invention has an airtight oil tank 11, and a circular oil mark 12 is provided on the outer surface of one side of the airtight oil tank 11, and the circular oil mark 12 can be used to indicate that the hydraulic oil is added into the oil tank. Location. The oil pump motor unit 13 is built in the airtight oil tank 11, the rated power of the oil pump motor unit 13 is 2.2KW, and the power supply is AC380V, 50Hz. The oil supply flow rate of the oil pump motor unit 13 is 4 liters per minute. Once the system load is established, it can reach the rated pressure of 31.5Mpa in a very short time. The oil pump motor unit 13 is connected to one end of the check valve 14 through a pipeline, and the check valve can prevent high-pressure oil backwashing, thereby protecting the oil pump motor unit 1...

The invention provides a movable hydraulic pump station which comprises a sealed oil tank, an oil pump motor set, a one-way valve, an overflow valve, a prepressing air filter, a high-pressure shock-proof pressure gage, a motor starting circuit protection breaker and an oil leveler for measuring the height of liquid level in the oil tank. The movable hydraulic pump station is characterized in that a motor and an oil pump integrally form the oil pump motor set, the oil pump motor set is internally arranged at the bottom of the sealed oil tank, immersed below the hydraulic oil level of the sealed oil tank and connected with the one-way valve through a pipeline, the one-way valve and the overflow valve are integrated on a valve block in an inserted manner and arranged in the sealed oil tank, and the sealed oil tank is made of aluminum alloy materials. The oil pump motor set is compact and firm, and the movable hydraulic pump station has the advantages that the movable hydraulic pump station can work under a high-acceleration condition and the like.
Description
Technical field: [0001] The present invention relates to a mobile hydraulic power unit, especially capable of being used on mobile equipment with high acceleration performance. Background technique: [0002] At present, the structure of the common mobile hydraulic power station on the market is a combination of motors, oil pumps, valve groups, control switches, pipelines and fuel tanks. Usually, the motor and the oil pump used in the mobile hydraulic power unit are separated, which results in the separation of the motor and the oil pump, oil tank and valve group. The separate design makes this mobile hydraulic power unit bulky and heavy. The motor is connected to electricity to rotate, and then drives the hydraulic pump to rotate through the coupling shaft. The hydraulic pump absorbs oil from the fuel tank, outputs high-pressure oil from the oil outlet, and enters the control valve group through the pipeline to achieve the required functions such as oil supply pressure and ...
