Slurry pump in use process should pay attention to the problems are many, but according to the standardized operation can significantly increase the service life of the slurry pump, prevent the occurrence of accidents, reduce the damage, so as to reduce running cost.
1,In the running of pump, in addition to monitoring flow, pressure, also monitor motor do not exceed rated current; Whether at any time to check the oil seal and bearing guide often occur; Pump whether fit or overflow phenomenon such as pool, and processing at any time.
2, Before the shipment of slag pulp pumps should open the inlet valve of the pump, close the outlet valve of the pump, and then start the pump. Pump starts slowly again to start the pump outlet valve, pump outlet valve opening size and speed, should be to exceed constant current pump and motor vibration not standard.
3,Dredging pump mainly for the purpose of conveying flow, so the best mount flowmeter in running monitoring system (meter), to monitor the flow meets the requirements; In line with cyclone system, cinder flushing system, pressure filtration dehydration system also requires pipe has a certain pressure at the exit. So, in this kind of system should also be fitted with a pressure gauge to monitor the pressure is in line with the requirements.
4, Dredging series pump start-up, also follow the above method. Just after the opening level of pump, the level at the end of the pump outlet valve can be opened a little (open the size of the first pump motor current should be a quarter of the rated current), and then can be successively started secondary level 3 until the end of the class, all series pump starts, you can gradually open at the end of the big stage pump outlet valve and the size of the valve opening speed, should with pump vibration and not as a primary pump motors are not excess current to master.
In strict accordance with the above specification operation, can avoid artificial damage, increase the service life of the slurry pump accessories. |
