Principle and classification of fristam pumps fzx 2000 mixer pump.

Pump is a machine used to inhale or deliver liquids or gases, which uses pressure differences to generate fluid motion energy. Pump is widely used in various fields, such as agriculture, water conservancy, environment, chemical industry, petroleum, etc.
Pumps can be divided into two categories: volumetric pumps and dynamic pumps.
Volumetric pump refers to a pump that achieves the transmission of liquid or gas by changing the volume of the working chamber. It has the characteristics of stable flow, high pressure, and strong self priming ability, but also has the disadvantages of complex structure, high operating noise, and high maintenance costs. Volumetric pumps can also be divided into reciprocating pumps and rotary pumps. Reciprocating pump refers to a pump that changes the volume of the working chamber by reciprocating movement of a piston or plunger in the cylinder, such as a plunger pump, diaphragm pump, etc. Rotary pump refers to a pump that changes the volume of the working chamber by rotating the rotor or blade inside the housing, such as gear pump, screw pump, vane pump, etc.
Dynamic pump refers to a pump that achieves delivery by accelerating a liquid or gas. It has the characteristics of simple structure, stable operation, convenient maintenance, etc., but also has the disadvantages of large flow rate affected by pressure, low efficiency, etc. Dynamic pumps can also be divided into centrifugal pumps and axial flow pumps.
