The air compressor is generally used in large gas volume occasions. The matched motor power is relatively large, the frequent start and stop has a great impact on the power grid, the current is large during start-up, the heating capacity of motor coil is also relatively large, and the motor is easy to burn if it is started and stopped too frequently. The following describes how to avoid frequent start and stop of air compressor.
1. The cleaning and adjustment of the oil system of the air compressor unit are qualified, the oil quality test meets the requirements, and the oil storage is moderate. Check the main oil tank, oil filter and oil cooler. If the oil level in the oil tank is insufficient, add oil. Check the oil temperature of centrifugal air compressor. If it is lower than 24 ℃, use heater to make the oil temperature above 24 ℃. Oil cooler and oil filter shall also be filled with oil and air shall be discharged. The switching position of oil cooler and filter shall be switched to the side to be put into use.
2. Check the main oil pump and auxiliary oil pump of the air compressor to confirm that they work normally and turn correctly. The oil thermometer and pressure gauge shall be complete, with qualified measuring range and normal operation. Fill the accumulator with dry nitrogen to keep the gas pressure in the accumulator within the specified value. Adjust the oil pressure of the oil circuit system to meet the design requirements. Check that various interlocking devices of the oil system operate normally to ensure the normal and stable operation of the air compressor.
3. Adjust the valve on the process gas pipeline to a certain position according to the starting requirements. Generally, the inlet and outlet valves of the air compressor shall be closed, the return valve or vent valve for anti surge shall be fully opened, and the outlet valve to the process system shall also be fully closed. The switches of various valves shall be flexible and accurate without jamming.
The above is the reason to avoid frequent start and stop of air compressor. For more news information, please continue to pay attention to the website. We will update relevant news information from time to time for your reference. Please look forward to it.
