The exhaust temperature plateau of the injection water cooled screw air compressor is solved.
In the petrochemical industry, fuel injection screw air compressor, with its reliable operation, high efficiency, long life and volume is not affected by the exhaust pressure, and the advantages of stable operation without surge, has been widely used. Especially in the utility system as a kind of advanced aerodynamic equipment, it is widely used in air pressure station to provide air for instrument wind. Therefore, the safe operation of the air compressor ensures the stability of the instrument wind and the safe operation of the device. In the daily operation of the air injection screw air compressor, due to the poor maintenance, the unit often has high exhaust temperature alarm and unit chain shutdown failure. Therefore, the high exhaust temperature alarm, screw air compressor unit stop of a detailed analysis of fault chain, and puts forward practical and effective treatment methods for it, in order to ensure the normal running smoothly of screw air compressor is very important.
(1) event description
On May 15, 2016, the air compressor unit of production operation is J - 6001 - a chain down suddenly, inspection found that the PLC screen shows high exhaust temperature alarm, high pressure difference alarm, oil oil and gas separator filter high pressure difference alarm chain downtime. In order to ensure the safe operation of the equipment production, replace the standby unit j-6001b, and the fault unit j-6001a is down for maintenance.
(2) brief introduction of maintenance.
On May 16, 2016 at 8:30, J - 6001 - a failure unit for maintenance, for its high exhaust temperature alarm, high pressure difference alarm, oil oil and gas separator filter high pressure difference alarm chain outage, the contents of a major overhaul for oil system and circulating water cooling system for maintenance. From the perspective of maintenance, there are mainly problems in the following aspects:
1) fouling and blockage of filter core of oil and gas separator;
2) blockage of oil filter;
3) failure of oil breaker valve and valve core card;
4) temperature control valve fault card dead;
5) serious fouling and blockage of oil cooler.
