What is the stroke of a reciprocating pump?
Thread Content
Does this stroke refer to the distance the piston travels from left to right, or does it refer to the distance it travels back and forth from left to right and then from right to left? This post was last edited by liuwenqiu on 2009-3-31 17:08.]
As the piston moves from left to right, a negative pressure is created inside the pump cylinder, causing the liquid in the reservoir to enter the pump cylinder through the suction valve. As the piston moves from right to left, the liquid inside the cylinder is compressed, resulting in an increase in pressure, which then causes the discharge valve to open and close. One back-and-forth movement of the piston, with liquid being drawn in and discharged once each, constitutes one working cycle ； This type of pump is called a single-acting pump. If the piston makes one back and forth movement, sucking in and discharging liquid twice each time, it is called a double-acting pump. The movement of the piston from one end to the other is called a stroke.
