Abstract

The utility model relates to a submerged pump which belongs to a universal machine. A guide blade and an impeller wheel are arranged on the shaft, and spacing collars are arranged outside the impeller wheel and the guide blade. The pump housing is sheathed on the shaft, and the pump housing is connected with a water inlet housing and a water outlet housing. The utility model has the advantages of small radial dimension, simple structure, easy manufacture, simple installation and disassembly, and convenient maintenance, and is applicable to field irrigation, sampling of water quality of oilfields, frontier defense, and construction sites.

Description

Submersible pump

The utility model is a kind of water supply submersible pump, belongs to universal machine.

The submersible pump of producing is the water filling type submersible pump at present, and the submersible pump of this structure because pump housing radial dimension is big, is tried out in the well of larger caliber and used, and for small-bore well, can not use this pump.

The purpose of this utility model provides a kind of little submersible pump of radial dimension that uses in small-bore well of trying out.

The utility model is that following technological scheme realizes: former submersible pump guide vane structure is an open type, and the blade upper end is not sealed, and former blower inlet casing 31 structures is changed in stator 14 upper ends add upper cover plate 25, by upper cover plate fixed guide vane position.Form closed runner.Adopt thin-wall steel tube to make pump case 11, fix position limit cycle 12, two ends are with scyewed joint water inlet shell 1 and go out water hull 22.

Key 8 is contained on the axle 16, and coupling 4 is installed on the axle 16.Pin 7 connects coupling 4 and axle 16 fastening.Protecting jacket 5 is positioned on the coupling 4, and screw 3 is screwed into protecting jacket 5 and plays the role of fastening with coupling 4.Axle sleeve 9 penetrates and is contained on the axle 16, and key 15 is contained on the axle 16, and bearing 10 is adhesive in on the water shell 1, with four screws 3 water strainer 2 is screwed in on the water shell 1, axle 16 is contained in in the water shell 1, position limit cycle 12 penetrates axle 16, impeller 13 is contained on the axle 16, and stator 14 penetrates axle 16 and is contained on the position limit cycle 12.Axle sleeve 9 penetrates axle 16, and being inserted in packing ring 17 with bolt 18, to be screwed into spool 16 ends fastening.Pump case 11 is inserted in position limit cycle 12, connects with the water inlet shell.Safety check 19 is put on valve pad 20 pack in the water hull 22, screw 21 is screwed into out water hull 22, and pump label 23 is attached to out on the water hull 22.Go out water hull 22 and connect with pump case 11, protective board 24 usefulness screws 3 are screwed into pump case 11, water inlet shell 1 with go out water hull 22.

It is little to the utlity model has radial dimension, simple in structure, is easy to processing, makes installation, dismounting, easy to maintenance, widely used characteristics.

Now in conjunction with the accompanying drawings the utility model is described in further detail.

Fig. 1 is that the utility model master looks sectional view.

Fig. 2 is the utility model stator part partial enlarged drawing.

Fig. 3 is former submersible pump blower inlet casing part partial enlarged drawing.

Fig. 1-2 is the utility model specific embodiment: former submersible pump blower inlet casing and stator shape and structure are improved.Change in stator 14 upper ends and add a upper cover plate 25.Position limit cycle 12 penetrates axle 16 and is contained in the pump case 11.Key 8 is contained on the axle 16, and coupling 4 is installed on axle 16, and pin 7 is with coupling 4, and axle 16 connects fastening.Protecting jacket 5 is installed on the coupling 4, and it is fastening with coupling 4 that screw 3 is screwed into protecting jacket 5.Axle sleeve 9 penetrates and is contained on the axle 16, key 15 is contained on the axle 16, bearing 10 is adhesive in on the water shell 1, with four screws 3 water strainer 2 is screwed in on the water shell 1, axle 16 is contained in in the water shell 1, position limit cycle 12 penetrates axle 16, and impeller 13 penetrates and is contained on the axle 16, and stator 14 penetrates axle 16 and is contained in the position limit cycle 12.Axle sleeve 9 penetrates axle 16, and being inserted in packing ring 17 with bolt 18, to be screwed into axle 16 ends fastening, and pump case 11 is inserted in position limit cycle 12, with the connection of water inlet shell 1.Safety check 19 is put on valve pad 20 pack in the water hull 22, screw 21 is screwed into out water hull 22, and shell label 23 is attached to out on the water hull 22.Go out water hull 22 and connect with pump case 11, protective board 24 usefulness screws 3 are screwed into pump case 11, water inlet shell 1 with go out water hull 22.
