Stainless Steel Multistage Centrifugal Pump Common Problems and Solution

Stainless Steel Multistage Centrifugal Pump Common Problems and Solution
Stainless steel multistage centrifugal pump is made of Denmark advanced technology, it’s biggest advantage is the hydraulic model of advanced design, high efficiency, high energy saving. Pump internal impeller, pump housing and its main components using stainless steel stamping forming, the flow channel is particularly smooth, bushings, bushings with carbide, with superior service life, to avoid secondary pollution. Shaft seal with wear-resistant mechanical, no leakage. Motor Y2 lead shell, imported bearings, insulation grade F-class. Stainless steel multistage centrifugal pump running smoothly, low noise, the whole quality and reliable, beautiful appearance, small size, light weight, easy transportation, is the ideal green, environmental protection, energy saving pumps.
Stainless steel multi-stage centrifugal pump intermittent work of seven reasons:
1, Stainless steel multi-stage centrifugal pump stuffing box packing or seal wear, so that the air leaked into the pump casing
Solution:
Check packing or seal and replace as needed. Check the lubrication is normal.
2, Impeller or pipeline blocked
Solution:
Check for obstructions.
3, there is leakage of air or stainless steel multistage centrifugal pump inlet pipeline
Solution:
Check inlet piping for cavitation and / or air leaks.
4, suction is too high
Solution:
Check the existing net head (stainless steel multistage centrifugal pump inlet line is too small or too long will cause a great friction loss).
5, pumping hot or volatile liquid suction head shortage
Solution:
Increase suction head.
6, the end of the valve or inlet pipe immersion depth is not enough
Solution:
Consult the pump manufacturer for the correct immersion depth and remove vortex with baffles.
7, stainless steel multi-stage centrifugal pump shell gasket damage
Solution:
Check the condition of the gasket and replace as required.
Stainless steel multistage centrifugal pump With the application of more extensive industry, the use of common problems have become more and more, China Botou Haina Pump Co., Ltd. after a multi-directional knowledge concluded that this stainless steel multistage centrifugal The key to pump installation technology is to determine the pump installation height. This height refers to the vertical distance from the water surface of the water source to the center line of the pump impeller. It is not confused with the allowable vacuum height. The allowable vacuum height indicated on the pump nameplate or product manual means the vacuum value on the water inlet section of the pump, Is at standard atmospheric pressure; water temperature of 20 degrees Celsius, the test was measured. It does not consider the condition of the flow of water after the water pipe is supplied.
