Static tests related to propylene compressors

Centrifugal or piston? Get in touch to check the API standards

Since there is no specific data, I can briefly explain it as follows: 1) Establish a dry gas seal and a lubricating oil system; slowly open the bypass valve adjacent to the outlet safety valve of the operating pump. When the pressure drops to the interlock value, check whether the standby pump starts automatically. Let the oil pressure continue to drop and see if the shutdown interlock is triggered. 2) Top up the hot well with liquid to establish circulation, allowing the liquid level to rise or fall; check whether both pumps operate when the level is high and high, and whether the pumps stop operating when the level is low. 3) After the oil system is established, close the main steam valve to prevent steam from entering the compressor. Start it according to the normal procedure; after the quick shut-off valve opens, conduct two tests by pressing the shutdown button both at the control panel and on-site to see if the machine can shut down properly. Try again later to see if shutting it down manually (using the mechanical device) can stop the compressor. 4) Start the machine according to the normal procedure without introducing steam, and conduct a test on the travel of the speed control valve. 5) Ride-through test: check whether the vehicle jumps out once the mechanical jump-out speed is reached. Let’s keep it brief: while driving, the manufacturer is present to assist, and experiments are carried out one by one according to the manufacturer’s requirements. If certain conditions cannot be met, you can contact the instrumentation staff to conduct an inspection and take action.
