Abstract

Serial Number	Measuring Point Name	Thermal Alarm Signal	Automatic Protection
I. Temperature
1	High Exhaust Gas Temperature in Each Section	Should	Automatic Shutdown
2	High Compressor Bearing Temperature	Should	Automatic Shutdown
3	High/Low Lubricating Oil Tank Temperature	Should	Automatic Shutdown
4	High Compressor Motor Stator Temperature	Should	-
II. Pressure
1	High Exhaust Pressure in Each Cylinder Section	Should	-
2	Large Air Filter Differential Pressure	Should	-
3	Low Lubricating Oil Pressure	-
4	Large Oil Filter Differential Pressure	Should	-
5	High/Low Air Compressor Cooling Water Inlet (After Valve) Pressure	Should	-
6	Low Air Supply Pressure in the Main Pipe of the Air Compressor Station	Should	-
III. Flow Rate
1	Low Air Compressor Cooling Water Inlet (After Valve) Flow Rate	Should	-
IV. Level
1	Low Lubricating Oil Tank Level	Should	-
V. Mechanical Quantity
1	Large Compressor Shaft Vibration	Should	Automatic Shutdown
2	Large Compressor Shaft Displacement	Should	Automatic Shutdown
3	Compressor Surge	Should	Emergency Relief
VI. Others
1	Air Compressor Unit Control Power Failure	Should	-
Note: 1. When the parameters of the alarm device are abnormal, an alarm should be triggered. If the alarm value continues to exceed the limit, automatic emergency relief or shutdown should be performed; 　　2. The installation of the thermal alarm and automatic shutdown device for the air drying and purification device is the same as Table D.

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.
