Disassembly sequence and methods of the horizontal multi-stage centrifugal pump

remove the order of the multistage centrifugal pump, remove the method of multistage centrifugal pump

a, horizontal multistage centrifugal pump structure

2, the order of the horizontal multi-stage centrifugal pump and remove the horizontal multi-stage centrifugal water pump method

with 3 horizontal multi-stage centrifugal pump structure & ndash; 7 for example remove ( 1) Bearing body removed first remove front and back of bearing body ask connecting bolts, then will be bearing, together with the bearing seat along the axial extraction. ( 2) Packing gland between remove the screw press cover and pump body connection nut, take out along the axial gland, remove the packing. ( 3) The removal of end cap unscrewing the end cap to the rear section of the connection between nut, remove the end cap. Then, the balance disc and balance board down. ( 4) Poles remove screw the nut on both ends of the poles, can be pulled out. ( 5) In the back of the demolition hammer period after the tap, made after the release of the removed. ( 6) The removal of the impeller with wooden hammer or lead tap around the impeller can be removed. If have rust on the shaft, impeller can use kerosene first dip, and then split.

( 7) Remove the hammer in the central part of the tap around the middle of solution can be removed, such as down not bottom levers available along the middle two feet move is desirable. Middle removed, you can be made of it in the small mouth ring, block set down and guide vane at the same time. According to the piecewise, until recently ( Inhalation) 。 Should be paid attention to during the process of disassembly, removed after the middle of a few axis is in the midst of cantilever state, in order to prevent the shaft bending, should add a temporary support will be suspended shaft. In addition, remove the impeller, keys, guide vane, and other small parts and components, should be numbered and placed centrally. ( 8) Remove the pump shaft, down to the first 1 can be pulled out pump shaft.

described above horizontal multi-stage centrifugal pump belong to product of older model of multistage centrifugal pump is the most used horizontal multi-stage centrifugal pump on the market product, is the packing seal, seal form used the disadvantages of packing seal is the phenomenon, there will be a drop of water can change if you want to use not to drip of water related products: TSWA horizontal multi-stage centrifugal pump

if the installation location width limited can choose vertical multistage centrifugal pump installation we recommend to choose: light stainless steel multistage centrifugal pumps
