First, before the air load test run, install the air filter, install the suction and exhaust valves step by step, and then start the compressor to purge. The sweep should not be less than 30min until the exhausted air is clean;
Second, after purging, the suction and exhaust valves at all levels should be removed and cleaned. If there is no damage, install and restore immediately;
The procedure, pressure and operating time of the boost operation shall comply with the provisions of the equipment technical documents. When there is no stipulation, the exhaust pressure shall be continuously operated for 1 hour when the exhaust pressure is 1/4 of the rated pressure; when it is 1/2 of the rated pressure It should run continuously for 2h; when it is 3/4 of the rated pressure, it should run continuously for 2h; continuous operation under the rated pressure should not be less than 3h;
During the boost operation, the pressure should be gradually increased after the operation at the previous stage pressure is normal.
Compressors whose compression medium is not air. When using air for load test operation, the maximum exhaust pressure should meet the requirements of equipment technical documents;
Fifth, the oil pressure during operation should not be less than 0.10MPa, and the temperature of the lubricating oil in the crankcase or the fuselage should not be greater than 70 ° C;
The drainage temperature at all levels shall comply with the provisions of the equipment technical documents.
