- pneumatic ball valve Circulating pump and pump stop pump operation procedures

a, kai pump, check whether there is any looseness on electrical wiring, field and remote transmission instrument, control of pneumatic valve is qualified; Loose, stude screws, pipeline and examine whether the flange, pneumatic valve switch are flexible; , check the oil level of oil storage room ( Endoscopic or oil cup) And, if necessary, come on; To ensure that the motor has joined the right amount of lubricating oil (qualified Fat) ； , turn the coupling with the hand to turn, should feel relaxed and weight evenly, and pay attention to distinguish between pump with and without friction and foreign body rolling noise, if have, should try to rule out, and the coupling of the shield is installed; Pneumatic valve of imports and exports, circulating cooling water, open closed connected pneumatic valve, observation of circulating cooling water pipe on the pressure gauge; , open the pump suction pipe of pneumatic valve, make the liquid inside the pump, open the object completely dynamic valve, turn the coupling, eliminate gas inside the pump; Check the process pipeline in pneumatic valves should be in the open pump position; , close the export pipeline pneumatic valves, start the motor; , for the pump speed stability, ammeter to designated location, after the pump pressure gauge indicating rising, slowly open the export pipe pneumatic valve, adjust the outlet flow according to the technical requirement. And comprehensive examination without exception, such as found serious leakage, vibration, metallic sound, the high temperature rise phenomenon, stop the pump immediately. Second, stop the pump: pneumatic valve, pump export; Stop, press the pump button, pay attention to the motor idle away time. And close the inlet pneumatic valve, and the process to disconnect ( If necessary) 。
