Five multi-stage pump failure pump power consumption is too big reasons: 1. Fever 2. packing too tight and the flow is set too high and the housing 3. The rotor has a grazing 4. 5. pump shaft bearing wear bending solution. : an appropriate filler relax pressure off a small valve opening degree 2. 3. trimmed rotor position with the housing 5. 4. Replace the bearings replaced or corrected failure Six pump vibration greater reason: a partial blockage 2. impeller impeller damaged 3. The flow is too small and the motor shaft misalignment 4. 5. 6. mixed with air bearings damaged cavitation workaround: 1. Removing foreign body removal 2. Replace the outlet valve slightly open impeller 3. 4. 5 point alignment. Inhalation position change. improve water pipe D DG46-30X3 D DG46-30X4 D DG46-30X5 D DG46-30X6 D DG46-30X7 D DG46-30X8 D DG46-30X9 D DG46-30X10 D DG46-30X11 D DG46-30X12 boiler feed pumps Hot water circulating pump manufacturers D DG100D-45X3 is a multi-stage pump designed to meet the needs of users of high efficiency and long life of advanced multi-stage centrifugal pumps multistage pumps, the use of foreign high efficiency water conservancy model 80d12x7 more stage pump, changed the design 100d45x3 traditional multistage pumps with balancing device multistage pumps, and accelerate the technological development of the high-pressure multi-stage pump. 100D-45X4 developed and manufactured in accordance with API610 standard in the industry living in technology leadership.
