Reciprocating pump working principle

Reciprocating pumps can be divided into single-action pump and multi-action pump, single-action piston reciprocating piston work once, suction, drainage alternately, each time, conveying fluid is not continuous; multi-action pump piston Equipped with valve chamber on both sides, each stroke of the piston is aspirating and draining, thus providing fluid continuity. Next, the working principle of the reciprocating pump will be analyzed and explained in detail. Reciprocating Pump Working Principle When the piston moves from left to right, a negative pressure is formed in the pump cylinder, and the liquid in the sump enters the pump cylinder through the suction valve. When the piston moves from right to left, the liquid in the cylinder is squeezed, the pressure increases, and it is discharged by the discharge valve. Pistons reciprocate, each suction and discharge a liquid, called a work cycle; this pump is called a single action pump. If the piston from time to time, each inhalation and discharge of liquid twice, known as double-acting pump. Pistons move from one end to the other end, called a stroke. The piston is driven by an electric crank-connecting rod mechanism, and the rotational movement of the crank becomes the reciprocating motion of the piston; or it is directly driven by the steam engine to reciprocate the piston; when the piston moves from right to left, a low pressure is formed in the pump cylinder, The valve is closed by the pressure of the liquid in the discharge pipe; the suction valve is opened by the effect of the low pressure in the cylinder, the liquid in the storage tank is sucked into the cylinder; when the piston moves from left to right, the suction valve is closed due to the increase of liquid pressure in the cylinder, Discharge valve open to the outside drainage. Thus, the reciprocating pump relies on the reciprocating motion of the piston to provide energy to the liquid directly in the form of pressure energy. Through the above description of the working principle of the reciprocating pump, it can be concluded that the reciprocating pump mainly relies on the piston motion, showing the importance of the piston on the reciprocating pump. As reciprocating pumps are increasingly used in many industries such as food, chemical, agriculture and medicine, accelerating understanding of the working principle of reciprocating pumps is very necessary and important for the work of these industries.
