Ammonia pump the correct steps and routine maintenance points

No matter what, we should pay attention to the correct operation steps and daily maintenance, to ensure its normal operation, today to introduce the correct operation of the ammonia pump and routine maintenance. Ammonia pump Ammonia pump The correct steps 1. Prepare the pump before the work (1) Check the pump and motor anchor bolts are tightened, the motor ground is reliable. (2) Check the coupling connection is good, crank rotation is flexible, installed safety shield. (3) Check the bearing tank oil, oil level. (4) Check the pump outlet valve, pressure gauge take pressure valve, exhaust valve, vent valve are closed. 2. Open the pump operation (1) Open the pump before the valve and exhaust valve, the liquid rushed to clear the pump before the pipeline air to close the exhaust valve. (2) start the pump (or pump), slowly open the pressure gauge valve, when the gauge pointer rises, slowly open the pump outlet valve, and adjust its opening, the pump flow to meet the technical requirements. (3) After the pump is operating normally, it is necessary to inspect the pump regularly, the running sound and vibration of the motor, the temperature and lubrication of the bearings and the motor, the temperature and pressure of the medium, and the flow rate. 3. Stop pump operation (1) Close the pump outlet valve. (2) Press the pump stop button to stop the pump. (3) Close the pump inlet valve. (4) until the gauge pointer complex zero, turn off the pressure valve. (5) to pump the liquid in the pump and the pipeline in winter to prevent freezing equipment. (6) tar pump to stop the pump before and after purging the pump with steam to prevent blockage. 4. Switching pump operation (1) Press the pump operation to open the backup pump. (2) slowly open the standby pump outlet valve at the same time, slowly closing the valve in the pump outlet. (3) After the standby pump is running normally, press the stop pump to stop using the pump. (4) Adjust the opening of the reserve pump valve, so that flow, current, etc. meet the technical requirements. Second, the routine maintenance of ammonia pump points 1. Often visit, control ammonia circulating ammonia tank temperature circulating at 75-780C, confirm the proper operation of the instrument. 2. Regularly drain the circulating ammonia to ensure that the recycled ammonia content meets the requirements. 3. The remaining ammonia in the remaining ammonia tank regularly sent to steaming ammonia or quenching coke, before sending ammonia to the remaining ammonia to carry out sewage work to ensure that the remaining ammonia content of qualified ammonia. 4. On time to supply high-pressure ammonia coke oven, and pay close attention to the circulating ammonia water tank during the supply of high-pressure ammonia to ensure the normal circulation of ammonia supply. 5. Often visit the circulating ammonia pump, high pressure ammonia pump, the remaining ammonia pump working conditions, to ensure that the equipment is operating normally, the instrument is working properly, abnormal abnormal timely reporting. 6. Keep the equipment clean, dust-free and grease-free, and keep the sanitation area responsible for cleaning. 7. Turn the spare equipment regularly to ensure flexible operation.
