Reciprocating Pump: Introduction, Air Vessels' Functions, and How Pumps Work Explained
Reciprocating pumps are devices used to move liquids or slurries by utilizing a piston or plunger. These pumps are characterized by their back-and-forth (reciprocating) motion, which creates a suction force to draw fluid into the pump and then pushes it out under pressure. This guide provides a straightforward explanation of how reciprocating pumps work, the role of air vessels, and practical applications.
Introduction to Reciprocating Pumps
Reciprocating pumps operate through a piston or plunger that moves in a linear motion inside a cylinder. The movement of the piston creates a vacuum that draws fluid into the pump through an inlet valve. As the piston moves back, it closes the inlet valve and opens the outlet valve, pushing the fluid out under pressure.
How Reciprocating Pumps Work
Piston and Cylinder Design:
The piston or plunger is sealed inside a cylinder.
Valves control the flow of fluid into and out of the pump.
Reciprocating Motion:
Suction Stroke: During the forward stroke of the piston, the volume inside the cylinder increases, creating a vacuum that draws fluid through the inlet valve.
Discharge Stroke: During the backward stroke, the piston decreases the volume inside the cylinder, closing the inlet valve and opening the outlet valve to push the fluid out.
Types of Reciprocating Pumps:
Single-acting pumps: These pumps have one side of the piston pressurizing and the other side sucking
A double-acting reciprocating pump is a type of positive displacement pump that operates with pistons or diaphragms to move fluid in both directions of the stroke. This guide provides a clear explanation of how double-acting reciprocating pumps work and their practical applications.
