Open pump station for crossheading crusher

The open type pump station comprises a hydraulic oil tank, an electromagnetic directional valve, an overflow valve, an oil supplementing one-way valve and a plunger pump, an oil inlet and an oil outlet of the plunger pump are connected with a pressure oil port of the hydraulic oil tank and a pressure oil port of the electromagnetic directional valve respectively, and the oil supplementing one-wayvalve is connected between the pressure port and an oil return port of the electromagnetic directional valve. And the circulation direction of the oil supplementing one-way valve is from the oil return port to the pressure port. The hydraulic pump station for driving control of the crossheading crusher has the advantages that the motor connected to the machine body is small in size and weight andcan be used for a long time under the overload condition without shutdown maintenance, the motor is not directly connected to the machine body and is not prone to damage, and the size, the rotating speed and even the power of
