different grades. When the lubricating oil is replenished, it is necessary to make sure that there is no
pressure in the system before opening the oil cap.
4.2.3 Observe that the oil level should be ten minutes after shutdown. During operation, the oil
level may be slightly lower than when the oil level is stopped.
4.3 Matters needing attention in operation.
4.3.1 When there is abnormal sound and abnormal vibration during operation, stop
immediately.
4.3.2
There is pressure in the pipeline and container in operation,
do not loosen the line or
embolism or open unnecessary valves.
4.3.3 The internal dust and dirt of the machine can not be removed by using the blowing
device in operation (the residual gas in the oil and gas barrel or the gas in the external gas
storage tank can be used to remove the residual gas in the oil and gas tank of the machine
when downtime). However, it can be used to blow other air compressors that are notstarted.
4.3.4
If it is found that the oil on the oil level gauge cannot be seen during long-term
operation and the exhaust gas temperature is too high, it should be shut down immediately.
Stop for 10 minutes to observe the oil level, if insufficient when there is no pressure in the system
to replenish the lubricating oil.
4.3.5 There will be condensate water in the rear cooler and cyclone type air-water separator.
Discharge or install an automatic drain device regularly every day, otherwise the water will be
brought into the system.
4.3.6 Check the recording voltage, current, air pressure, exhaust temperature and oil level every 2
hours in operation for future inspection and repair.
4.4 Treatment method of long-term shutdown
During long periods of downtime, the following methods should be carefully followed,
especially in high humidity seasons or areas.
4.4.1 After three weeks of downtime
1) Electric equipment such as electric motor, starting disk, etc., wrapped in plastic rubber paper
or oil paper, to prevent moisture from invading.
2) Completely discharge water from oil cooler and rear cooler.
