Fasteners (bolts) is two or more than two member fixedly connected into a whole, or the use of a certain class of mechanical parts, bolt spread to every corner of Haoyuan company device. Both static equipment, pipeline or equipment, as long as the equipment to have its existence, and the bolts of the performance is good, will be directly related to the use of safety equipment.

So, to do a good job in the basic management of equipment, equipment to prevent accidents caused by failure of fastener performance. At the beginning of 7, the power of organization personnel flange, to old factory equipment pipeline valves bolt, compressor, cycle machine, a pump, pump, copper ammonia pump machine cylinder head bolts and compressor valve cover bolts and other special inspection.

Examination content includes: there is no false bolt, the bolt is fastened in place of compressor, a stress is uniform, the main pipe flange, valve bolt corrosion.

Aiming at the problems existing in different examination, repair personnel were oil protection, replacement bolts, some did not replace the bolt strengthen the monitoring and inspection work. For the compressor repeated replacement valve, causing the bolt hole wire cylinder on the bad, cause the individual false bolt, requirements of equipment management personnel to the problems of rectification.

Equipment to the long-term stable operation, we must do the basic work of equipment management. Even bearing cap bolt looseness, may also damage the crankshaft caused by the compressor. Therefore. Therefore, in the daily maintenance and inspection, carefully do the inspection work. Is the so-called "qianlizhidi were destroyed in Yixue", we will "nest", nipped in the bud, to ensure the safe and stable operation of the equipment.
