we should pay more attention to centrifugal pump
1.prohibited no water running, do not adjust suction inlet to reduce emissions, prohibited operating under low flow,
2.monitoring operating process, completely prevent stuffing box leakage, when replacing the packing box should use new packing,
3.ensure mechanical seal with fully flush flow, water-cooled bearing forbids the use of excessive flow,
4.lubricant don't use too much,
5.Check according to recommended cycle. Establish operating records,
including operating hours, packing adjustment and replacement, adding
lubricant and other maintenance measures and time. For centrifugal pump
suction and discharge pressure, flow rate, input power, lotions and
bearing temperature and vibration condition should be regularly
measurement records.
6.centrifugal pump host depends on atmospheric pressure pumps lower
water to the higher, and atmospheric pressure only supports
approximately 10.3 m water column, so when the centrifugal pump host
leave the water 12 meters, then it cannot work
