Description BW250 mud pump|Horizontal Triplex Piston
The utility model discloses a double acting hydraulic cylinder mud pump, comprising a first pump cylinder, a double acting hydraulic cylinder, a second pump cylinder and a hydraulic oil control system. The pistons of the two pump cylinders respectively pass the piston rod and double acting hydraulic pressure. The pistons of the cylinders are connected, and the one-way valves at the outlets of the two pump cylinders and the one-way valves at the inlets are merged into the outlet pipelines and the inlet pipelines connected to the drilling fluid to be transported through the pipelines. The left and right ends of the double-acting hydraulic cylinders are respectively provided with Buffered confined space and buffered confined space are all connected with the pressure relay. The left and right ends of the double-acting hydraulic cylinder are respectively connected with the hydraulic oil control system through the oil passage A and the oil passage B. When the buffer confined space reaches the pressure relay setting value, the corresponding The pressure relay sends electrical signals and controls the hydraulic oil control system to supply oil to the oil circuit A or oil circuit B to drive the piston movement of the double-acting hydraulic cylinder, thereby driving the two pump cylinders to move through the piston rod to realize the drilling fluid delivery. The device is light in weight, small in size, and has a large delivery flow.
