Described non-contact type sealing configuration 6, by the inner ring and 5 contact seals of stuffing box packing seal ring of sealing plectane 6.1, outer circumferential edge and volute casing sealing do not contact with volute casing housing 7.1, the pump housing (worm gear) 7.2, hypomere major axis 1.2.Shown in Fig. 5,6.

The described volute casing pump housing 7 by the pump housing (worm gear) 7.2 and middle dowel hole 7.2.1 thereof, fix with the bottom of the hypomere major axis 1.2 of two sections axles 1, and the installation supporting frame 7.3 of volute casing housing 7.1 constitutes.With the below of volute casing housing 7.1, be mounted with conical pipe 7.4.Shown in Fig. 1,8.

Described water outlet adapter and slip joint 8 refer to that one is the water outlet UNICOM of the volute casing of water outlet adapter and recycle pump, and the other end is the water that pumps to be delivered to the place that needs by the slip joint pipeline.As shown in Figure 1.

Working principle of the present utility model and advantage are:

1, the function of two sections axle construction is when recycle pump is wanted inspection and maintenance, and the parts such as dismounting motor of just needn't taking a lot of effort only need the flange bolt on two joints is disassembled, and can carry out routine and overhaul.

2, the utility model had both made the axle center can reach highly consistent owing to adopted combination bearing to adjust structure and many anchor rings cooling water channel device, and when bearing was worked in the long term, the cooling problem of bearing had obtained solving well.

3, the utility model has adopted new packing ring water filling sand surfing, many places axle envelope and contactless sealing structure.Both solved that silt covers and, reduced the friction ractor of sealing again, the overall efficiency and the working life of having improved recycle pump, solved " run, drip, leak " problem of traditional water pump with axle to the quick wearing and tearing of main shaft.
