- Jul 13, 2018 -

Main parts

Pump cylinder, piston, piston rod and suction valve, 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 tank is inhaled The valve enters the pump cylinder. When the piston moves from right to left, the liquid in the cylinder is squeezed, the pressure is increased, and the discharge valve is discharged. Reciprocating piston once, each inhalation and discharge a liquid, known as a work cycle, the pump is called a single pump. If the piston back and forth once, each inhalation and discharge two times liquid, called the dual-action pump.

The piston moves from one end to the other, called a stroke.
