A single cylinder reciprocating pump working principle Piston reciprocating once, that is, two stroke, the pump only inhaled and discharged liquid once, alternating, conveying liquid is not continuous, known as single action pump, also known as single cylinder reciprocating pump. When the piston is moved to the side by the external force (driven by the movement of the crank mechanism of the power section), the volume of the working chamber in the pump body becomes larger and the pressure drops. The discharge valve above the pump is automatically closed (by spring or gravity) The suction valve below the pump closes automatically and draws liquid into the pump. When the piston to move in the opposite direction, the pump body becomes smaller, resulting in high pressure, the suction valve is automatically closed, the discharge valve is top open, the liquid discharged from the pump. Second, the reciprocating pump works Double cylinder reciprocating pump works and the principle of single cylinder pump is the same, the difference is that the two cylinder reciprocating pump has two pump cylinders, so in a work cycle, the pump sucked and discharged Liquid twice each.
