1. The meaning of reciprocating piston pump is reciprocating piston pump. This is a pump that pumps liquid and increases liquid pressure by reciprocating the piston in the pump cylinder. Here are some key points about reciprocating piston pumps: Working principle: By the reciprocating motion of the piston in the pump cylinder, the working volume in the pump cylinder is changed, thereby achieving the suction and discharge of liquid. When the piston moves forward, the working volume inside the pump cylinder decreases and the liquid is squeezed out; When the piston moves backwards, the working volume inside the pump cylinder increases and the liquid is sucked in. Application scenario: Reciprocating plunger pumps are commonly used in applications that require high-pressure liquid transportation, such as petroleum, chemical, metallurgical, mining, and other fields, due to their ability to generate high pressure. Characteristics: It has the advantages of simple structure, reliable operation, and easy maintenance, but at the same time, it also has disadvantages such as large flow pulsation and high noise. In summary, reciprocating piston pump, also known as reciprocating piston pump, is an important liquid conveying equipment. 2. sdnand sdnand
