Abstract
The utility model discloses a pressing device of hydraulic cylinder, which includes an electromotor, and an oil pump; the electromotor is connected with the oil pump; the pressing device of hydraulic cylinder is characterized in that the oil pump is connected with a one-way valve through a pipeline; the one-way valve is connected with a high-pressure ball valve through a pipeline; a tee joint is arranged between the one-way valve and the high-pressure ball valve; the tee joint is connected with a relief valve; the high-pressure ball valve is connected with a reversing valve; and the reversing valve is connected with the hydraulic cylinder through the one-way valve, and the high-pressure ball valve. The working principle of the pressing device of hydraulic cylinder is as follows: the electromotor drives the oil pump to pump out hydraulic oil; the pressing pressure needed by different hydraulic cylinders is adjusted through the relief valve; and the pressing pressure is displayed through a pressure gage. The hydraulic cylinder realizes to extend and retract through manually controlling the reversing valve; and the hydraulic cylinder after moving in place can be displayed by the pressure gage at the two sides of the hydraulic cylinder. The pressing device of hydraulic cylinder has a simple structure, and is convenient to be used.
