Chemical equipment is generally divided into two categories: static equipment and dynamic equipment. Static equipment refers to equipment that is at a standstill after installation and does not require power transmission during production operations. Dynamic equipment refers to rotating equipment driven by a driving machine, such as pumps, compressors, fans, motors, and forming machines, packaging machines, mixers, etc.

Pumps for chemical plants are mainly divided into three categories, namely centrifugal pumps, reciprocating pumps and rotary pumps. Centrifugal pumps account for about 80%-90% of the total process pumps; reciprocating pumps have plungers that move back and forth to replace the liquid and force the liquid out of the outlet nozzle, including piston pumps, plunger pumps (metering pumps), and diaphragms pump: Rotary pump is used to transport heavier or higher viscosity materials, such as grease, asphalt, heavy fuel oil, etc., including gear pumps, screw pumps, etc. Fans mainly include induced draft fans, blowers, etc. Compressors commonly used centrifugal compressors, reciprocating compressors, etc.

The chemical industry process is complicated, involving many types of moving equipment and frequent failures. Effective monitoring of key equipment in the process, fully understanding the status of the equipment, and formulating effective maintenance plans can avoid unplanned shutdowns in production and reduce various losses. Freqx has sufficient knowledge base and long-term diagnosis experience for the above typical equipment, and can make accurate diagnosis in advance.
