There is a problem in the compressor in Bozhou station : when the new skid-base(skid-mounted) is equipped, because of high pressure(nearly 17Mpa), the problem of compressor will appear. There is a problem in the medium-pressure after the high pressure is increased. When PT101 detects high pressure, pov101 and pov151 will close successively,and then they will open and close not at the same time. It is so frequent to open and close to reduce pressure. Is it effective to protect the cross-head? Will it cause the pressure fluctuation which will do the damage to the sensor? For each time, the quantity of pov101 and pov151 close and open successively at least 11 times. Is it the reason that we change many ball valves? Will 101 ball valve and 151 ball valve be damaged in the condition in the future? Because Pov151 always stays open, all pressure goes in high pressure gas reservoir after 151 closes until the pressure reaches 25.7-26MPa, and then the alarm bell will and the machine will stop. When the pressure of in-letting gas is under 9Mpa, the machine works normally. Besides, 151 and 152 always staying open causes that the pressure flows backward, which destroys many single valves.
Please think about the rationality of 151valve and 152valve always staying open again and give the solution asap,if somewhere parameter problem? thank you!
