Description:
Reciprocating pumps include piston pumps, metering pumps and diaphragm pumps, commonly known as reciprocating pumps. It is a kind of positive displacement pump and is widely used. The reciprocating pump is a conveying machine that directly supplies energy to the liquid in the form of pressure energy through the reciprocating movement of the piston. According to the driving mode, reciprocating pumps are divided into two categories: motorized pumps (motor driven) and direct-acting pumps (steam, gas or liquid driven)
Features:
1. Strong self-priming ability;
2. The theoretical flow has nothing to do with the working pressure, only depends on the speed, the size of the pump cylinder and the number of actions;
3. The rated discharge pressure has nothing to do with the size and speed of the pump;
4. Uneven flow;
5. The speed should not be too fast;
6. Not very sensitive to liquid pollution;
7. The structure is more complicated, and there are many wearing parts.
