Compressor Troubleshooting and Solutions

This document is a user manual for equipment fault troubleshooting and solutions. It mainly lists six fault scenarios, and analyzes the possible causes and corresponding solutions respectively:

1. High unit exhaust temperature (exceeding 100°C)
– Possible causes involve various aspects such as lubricating oil level, cooling system, solenoid valve, motor, and sensor. For example, too low lubricating oil level, dirty oil cooler, and faulty oil – cut solenoid valve.
– Solutions include refueling, cleaning or replacing relevant components, and increasing cooling water volume.

2. High differential pressure of oil filter
– Possible causes are poor lubricating oil quality, un – reset differential pressure gauge, and dirty lubricating oil.
– Solutions include replacing lubricating oil, resetting the differential pressure gauge, and replacing the filter.

3. High differential pressure of air filter
– Caused by poor external environment, un – reset differential pressure gauge, and improper storage and use environment of the air filter.
– Can be solved by improving the environment, resetting the differential pressure gauge, and replacing the filter.

4. High unit oil consumption or high oil content in compressed air
– Related to lubricating oil quantity, oil return pipe, exhaust pressure, safety valve, etc. For example, too much lubricating oil, blocked oil return pipe.
– Solutions include adjusting oil level, cleaning the oil return pipe, and replacing the safety valve.

5. Oil Separator alarm
– Reasons include damage to separator – related components, overdue use of filters, and circuit faults.
– Solutions are to replace components, replace relevant filters simultaneously, and reset the differential pressure gauge.

6. Oil separator explosion and fire
– Caused by high temperature, poor environment, aging of electrical appliances/circuits, and static electricity.
– It is necessary to eliminate the causes of high temperature and static electricity, improve the environment, and replace electrical appliances/circuits.
