More complicated, assembly or disassembly is cumbersome, and maintenance is also inconvenient.
3rd, the content of the invention
In order to overcome the deficiencies in the prior art, the purpose of this utility model to be to provide a kind of reducing and install impeller end pump shaft
Eaily forced circulation axial-flow pump is repaired in cantilever, dismounting.
Realizing the technical scheme that the purpose of this utility model is used is：The forced circulation axial-flow pump is main by the pump housing, pump
Axle, impeller, pump cover and bearing body are constituted, and pump shaft is supported by bearing body, and the tail end of pump shaft is equipped with impeller；Near impeller end on pump shaft
It is sequentially arranged with mechanically-sealing apparatus and guide bearing；Guide bearing is located in support tube by support tube support, and its right-hand member is welded with pump cover
Together；Pump cover, bearing body and pump shaft constitute an entirety and are connected with the pump housing, and impeller end is located in the pump housing.
Described pump cover and support tube is provided with through hole, and the through hole is connected with interface is sealflushed.
Import and export in 90 ° degree elbow form of the described pump body design into pump.
Described pump cover and bearing body is provided with reinforcement.
The beneficial effects of the utility model are：Due to being equipped with guide bearing and mechanically-sealing apparatus on pump shaft, by support tube
Rotor part is supported, the cantilever of impeller end pump shaft is shortened, makes the rigidity increase of pump shaft, the stability of rotor part increases
By force, the service life of equipment is extended；Mechanically-sealing apparatus sealing is completely isolated with pumped (conveying) medium by axle, effectively prevents the mill of axle
Damage and corrode, reduce the maintenance cost of equipment；Pump cover, bearing body and pump shaft constitute an entirety and are connected with the pump housing, make pump
Structure is back pullout (BPO) structure, and rotor part can be fully drawn out, and dismounting maintenance is more convenient, time saving and energy saving；Through hole is rushed with sealing
The setting of interface is washed, being input into flushing liquor by interface can play cooling and lubrication to axle and guide bearing, reduce rotor portions
The mechanical breakdown that part is produced by temperature change；The import and export elbow form in 90 ° of pump, can be connected directly between on pipeline, without
Any support, convenience quick for installation；Pump cover and bearing body are provided with reinforcement, reinforcement and parts of Casting an into entirety, increase
Strong enabling capabilities.
