[yibomine jin]

   The centrifugal pump needs to pay attention to maintenance, 
which requires the operator to be very familiar with the water 
centrifugal pump, not only to have rich maintenance experience, 
but also to understand the working principle, disassembly, 
maintenance, installation, etc. of the centrifugal pump. The 
following is the removal and installation procedure of horizontal 
water centrifugal pump.

   Disassembly and assembly steps of horizontal clean water 
centrifugal pump:

   Before the installation of horizontal centrifugal pump, first 
check whether the parts are bumped and worn, clean them, and then 
assemble them.

   (1) First, tighten the connecting bolts and plugs on the 
corresponding parts.

   (2) Place the O-ring, paper pad, felt, etc. on the 
corresponding parts.

   (3) First, install the seal ring, packing ring, packing ring, 
packing gland, etc. into the pump cover in turn.

   (4) Install the rolling bearing on the shaft and then on the 
suspension, close the gland, press down the rolling bearing, and 
sleeve the connecting bolt on the shaft.

   (5) Install the shaft sleeve on the shaft, and then install the 
pump cover on the suspension. Install and tighten the impeller, 
stop washer, impeller nut, etc. Then assemble the above 
accessories into the pump, and tighten the connecting bolts on 
the pump body and pump cover.

   In the above installation process, the components that are easy 
to be ignored, such as O-ring, flat key and water retaining ring, 
can be put into the sealing bag.

 From step (5) to step (1), the disassembly sequence of the 
horizontal clean water centrifugal pump can be reversed.
