Multistage Pump Maintenance (1) Check multistage pump tubing and junction with or without loosening. Hand rotating multi-stage pump, and proved multistage pump is flexible. (2) was added to the bearing body bearing lubrication oil, observe the oil level should be the subject of the centerline of the oil, lubricating oil should be replaced or supplemented. (3) Remove the multi-stage pump pump diversion drain plug DG46-50X7 multistage centrifugal pump, filling water (or lead slurry). (4) Close the valve outlet road of import and export pressure gauge and vacuum gauge. (5) move the motor, and proved the motor rotation is correct. (6) start the motor, when the normal operation of the multi-stage pump, open the outlet pressure gauge and imports vacuum pump depending on its display after the appropriate pressure DG46-50X3 multistage centrifugal pump, centrifugal pump gradually open the valve, and check the motor load conditions. (7) try to control multistage pump flow and head on the label of the range to ensure a multi-stage pump at maximum efficiency point of operation to achieve maximum energy savings. (8) The multi-stage pump during operation, the bearing temperature must not exceed the ambient temperature of 35C, the maximum temperature not exceed 80C fault three gauge water pressure but still reasons: 1. too much resistance outlet pipe 3 2. Turn the wrong direction. The outlet pipe valve is not open impeller clogged Remedy: 1. Check or cord short pipe 2. Check the motor two intermodulation 3. Open the outlet valve 4. remove dirt fault impeller within four to reach the design flow reasons. : 1. 2. As the water level has reduced air intake submerged deep enough within the impeller 3. The rotor portion blockage severe wear solutions: 1. Check the leak site and the exclusion 2. extend deeper water pipe flooded depth 3. Dismantling and drops in addition to foreign bodies 4. Replace the seal ring DG46-50X7 multistage centrifugal pumps | centrifugal pumps | High-lift pump to be provided by the Anguo City Pump Co., Ltd. Shi Yuan. Anguo Shi Yuan Pump Co., Ltd.
