Steam pressure pneumatic valve the purpose of a test run and steps

a, steam decompression: the purpose of the pneumatic valve test run
steam pressure pneumatic valve is the purpose of the test run comprehensive check construction quality of each process before, at the same time can also be found that the mechanical equipment in the aspects of designing and manufacturing defects, and then do the final repair and adjustment, the running-in surface of clearance fit, the operation performance of equipment in line with the requirements of production, only after test run normally, mechanical equipment can be put into normal production according to the requirements of design.

2, steam pressure pneumatic valve test run steps:
test run of the program is after the first light load, full load after light load first, after the first single linkage, from low speed high speed, short after long term first.
equipment, commissioning requirements are different, respectively by special rules.

3, steam pressure pneumatic valve problems should be paid attention to in test run:
) Equipment after starting work, first of all, we should pay attention to the voice of the running, running normal voice should be uniform, smooth; If there is something wrong with, all kinds of noise occurs;
) Second often should pay attention to the temperature, the need to measure is generally, friction and oil temperature, cooling water temperature and outlet temperature of the air compressor to measure;
) In the test run shall check the status of sports institutions, to conform to the requirements;
) In the operation control system and brake system for test several times, should be sensitive, accurate and reliable to play the role of regulation;
) In the test run, seal should be good, and no fever;
) In the test run if found to have abnormal phenomenon, generally should immediately stop, and for inspection and repair.
