Shorting through the instrument switch, disconnect the experiment, auxiliary pump since the start of a good condition. Through the entire system even school, found that the pump outlet pressure is low when the pressure switch slow. Check the switch did not find abnormal switching. Lubrication pump outlet pressure low Interlock switch take pressure point In the pump outlet, the pressure switch installed in the switchgear, away from the pressure point between the pressure guide tube length of about 8m, and guide tube diameter smaller. When the oil pump outlet pressure is low, due to large pressure guide tube resistance, the measuring element can not be timely pressure relief, resulting in slow switching, the reaction lag, resulting in low oil pressure control interlock switch PSXL-08301, so that the carbon dioxide compressor jumped .
From the switching settings, under normal circumstances, the outlet pressure of lubricating oil is 1.2MPa, the control pressure is low, the jumping value of PSXL-08301 is 0.4MPa, the outlet pressure of lubricating oil pump is low, the setting value of PSXL-08404 is 0.6MPa, the two switches Action pressure is very close, so when the lubricant pump outlet pressure switch a little lag, it is possible to cause the first carbon dioxide compressor jumped, and then start the lubricating oil pump.
Interlock to improve the program and the effect The key to solve this problem is to reduce the low delay of the oil switch lag, start the auxiliary pump in time. To this end we will change the switch setting value from 0.6MPa to 0.8MPa, so not only reduce the lag time since the start switch, but also widened the interlocking jump value and auxiliary pump self-starting value of the distance, basically to avoid Jumping car switch ahead of the phenomenon. After several years of operation proved to be very successful transformation, not only did not appear to start the auxiliary pump lag phenomenon, there has been no sub-pump start frequently.
