Abstract

Serial Number	Measurement Point Name	Thermal Alarm Signal	Automatic Protection
I. Temperature
1	High exhaust gas temperature of the unit cylinder	Should	Automatic shutdown
2	Heater overheating of the adsorption air dryer with heating and regeneration	Should	Automatic shutdown
3	Overheating of the inlet air of the regenerator of the adsorption air dryer with heating and regeneration	Should	Automatic shutdown
4	Low evaporation temperature of the refrigeration air dryer	Should	Automatic shutdown
II. Pressure
1	High exhaust pressure of the secondary cylinder	Should	—
2	Low lubricating oil pressure of the air compressor transmission mechanism	Should	Automatic shutdown
3	Low cooling water flow (after valve) or low pressure of the air compressor unit	Should	Automatic shutdown
4	High pressure in the main water pipe of the compressed air station	Should	—
5	High pressure in the main air supply pipe of the compressed air station	Should	—
6	Low pressure in the main air supply pipe of the compressed air station	Should	—
III. Others
1	Failure of the air dryer controller	Should	—
2	Failure of the air compressor control power supply	Should	—
Note: An alarm should be triggered when the parameters of the alarm device are abnormal, and automatic shutdown will occur when the alarm parameters continue to exceed the limit.

Process system

The model, quantity of air compressors, and air supply systems with different air quality and pressure should be determined based on air supply requirements, compressed air load, and technical and economic comparisons. Within the compressed air station, the number of reciprocating or screw air compressors should be 3-6 units. For air supply systems of the same quality and pressure, the number of air compressor models should not exceed two. The number of centrifugal air compressors should be 2-5 units, and the same model should be used.
