Slurry overhaul What are the steps ? No matter what type of Slurry, before the overhaul, the device must understand the situation and know what parts may need to repair the damage to be replaced, and the spare parts ready in advance . Before stopping the pump , and then to conduct a detailed inspection equipment . Apply for work after the vote. Slurry overhaul before , to check whether the safety measures do complete, the pump pressure is put the net and so on. Centrifugal pump overhaul in order , is to disassemble , inspect, assemble three strides . Due to the different structure of the pump, the specific contents of the program is not the same . Slurry for 48Sh-22 cycle , work as follows:
The overall split but
( A ) Separating the pump casing
1 Removing the coupling pin , then pump and motor off .
2 Levels combined with bolts and disassemble the pin , so that the pump cover 2 and the lower pump off a separation. And remove the packing gland 12 .
3 Decomposition and system piping connections slurry pump manufacturer ( such as air duct 7 , sealed pipes ) . After the decomposition of the head with a cloth tube , to prevent falling into the debris.
(B ) Lifting the pump cover After completion of the above work and checks can be suspended pump cover . When lifting a smooth , careful not to get stuck with the other components.
(C ) Suspended rotor
1 . The bearing ends apart, take the bearing cap 14 and the bearing 16 ,
2 . Reversed the oil rings on both sides of the lower bearing 15 , mainly in the lower bearing lifting Buzhi Yu put out .
3 , Both ends of the rope to wear in the rotor ( the gland at ) lifting, to the level of safety.
