Reciprocating pumps for mine transportation include piston pumps, metering pumps and diaphragm pumps, commonly known as reciprocating pumps. It is a kind of positive displacement pump, which is widely used. Reciprocating pump is a conveying machine that directly provides energy to liquid in the form of pressure energy through the reciprocating motion of piston. According to the driving mode, reciprocating pumps are divided into motor-driven pumps (motor-driven) and direct acting pumps (steam, gas or liquid driven).

Main components of reciprocating pump for mine transportation: pump cylinder, piston, piston rod, suction valve and discharge valve.

working principle

When the piston moves from left to right, negative pressure is formed in the pump cylinder, and the liquid in the storage tank is inhaled

The reciprocating pump valve for mine transportation enters the pump cylinder. When the piston moves from right to left, the liquid in the cylinder is squeezed and the pressure] increases, which is discharged by the discharge valve. The piston reciprocates once, sucking and discharging liquid once, which is called a working cycle; This kind of pump is called single acting pump. If the piston goes back and forth once, and each sucks and discharges liquid twice, it is called double acting pump. The movement of the piston from one end to the other is called a stroke.
