Abstract
The utility model relates to an impeller and turbine shell gap regulator for a submersible pump, which solves the phenomenon of the contact friction of an impeller and a turbine of the submersible pump. The utility model is characterized in that a bearing seat (2) is provided with a sealing ring (9), a shim block (8) and holes embedded in a bearing (7), the upper end of the bearing (7) is supported tightly by a shim block (6) and a regulating nut (4), and the nut (4) is fixed with the shim block (6) via anti-loosing nails (5). The utility model has the advantages of energy saving and low power consumption; the service life of the submersible pump is prolonged.
Description
The utility model relates to a kind of submersible pump slack adjuster, belongs to a kind of submersible pump impeller and volute slack adjuster.
At present, QJ series diving pump structure is that the motor and the pump housing are integral mostly, and motor is last, and the pump housing is following.In fact, the axial force that acts on during pump work on the impeller sets passes on the thrust button by axle, wear and tear with high speed rotating gradually under responsive to axial force by the friction that umbrella shape piece and thrust button are formed, impeller descends with axle, make impeller and turbine come in contact friction, power consumption increases, and efficient reduces, the working life of also having reduced submersible pump simultaneously.
The purpose of this utility model is to avoid the deficiency that exists in the above-mentioned present technology, and a kind of submersible pump impeller and volute slack adjuster of contacting friction that overcomes impeller and turbine is provided.
The purpose of this utility model can reach by the following technical programs: this submersible pump impeller and volute slack adjuster, form by case, bearing support and pump shaft, bearing sleeve quilt cover clamshell behind pump shaft is solid, it is characterized in that: have the built-in hole of seal ring, bearing shim and bearing in the bearing support, the bearing upper end holds out against with pad and adjusting nut, fixes with locking nail between nut and pad.
The utility model has following advantage than above-mentioned prior art: owing to have the built-in hole of seal ring, bearing shim and bearing in bearing support, make after wearing and tearing between umbrella shape piece and thrust button, impeller descend with pump shaft, can pump shaft and impeller be mentioned by screwing adjusting nut, guarantee the relative gap of impeller and volute, prevent that impeller and volute from coming in contact wearing and tearing, reach energy-saving and cost-reducing, raise the efficiency, prolong the submersible pump purpose in working life.
Accompanying drawing 1 is a schematic representation of the present utility model.
To be further described the utility model below in conjunction with accompanying drawing:
As shown in Figure 1, this submersible pump impeller and volute slack adjuster are made up of case 1, bearing support 2 and pump shaft 10, it is solid by case 1 cover that bearing support 2 is placed in pump shaft 10 backs, and scribble sealer 3 on the screw thread, have shoulder hole in the bearing support 2, place " Y " seal ring 9, bearing shim 8 and bearing 7 in the hole, bearing 7 upper ends hold out against with pad 6 and adjusting nut 4, on nut 4 and the pad 6 a plurality of holes are arranged, 6 on nut 4 and pad are fixed in the hole with locking nail 5.After submersible pump uses a period of time, the wearing and tearing that umbrella shape piece and thrust button are formed, impeller descends with pump shaft, can cause impeller and volute to come in contact wearing and tearing this moment, and unload locking nail 5 this moment, screws adjusting nut 4 with spanner, determine to screw the number of turns according to abrasion condition, slightly loose half-turn screws in locking nail 5 to the hole of good adjusting nut 4 and pad after tightening, and has promptly finished the adjusting of impeller and volute relative gap.
Claims (1)
1, a kind of submersible pump impeller and volute slack adjuster, form by case (1), bearing support (2) and pump shaft (10), it is solid by case (1) cover that bearing support (2) is placed in pump shaft (10) back, it is characterized in that: have seal ring (9), pad (8) and the built-in hole of bearing (7) in the bearing support (2), bearing (7) upper end holds out against with pad (6) and adjusting nut (4), and is fixing with locking nail (5) between nut (4) and pad (6).
