Description
Technical field
The utility model discloses a kind of deep-well pump, belong to pump class field.
Background technique
Deep-well pump, in order to improve lift, needs multistage pressurization, because be provided with multiple impeller to carry out accumulation of energy to liquid.Because each worm gear spiral case assembly is separate individuality, need tie rod the worm gear spiral case tension be arranged in a row together, to ensure the integrity of structure and effective sealing.Tradition tie rod adopts hook structure usually in the Placement of water outlet joint part, although install more convenient, because tie rod is generally rectangular sheet structure, drag hook easily occurs distortion under larger pulling force, causes tie rod to lose the effect of tension.
Model utility content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of deep-well pump, and counter brace structure is improved, can each spiral case of more effective tension, ensures the integrity of sealing and structure.
For achieving the above object, the utility model provides following technological scheme: a kind of deep-well pump, comprise the pump housing, motor is provided with bottom the pump housing, it is water inlet joint between motor and the pump housing, pump housing top is water outlet joint, the described pump housing forms by some spiral cases are stacking, spiral case inside is provided with impeller, the tie rod straining described some spiral cases is provided with outside the described pump housing, tie rod head is provided with drag hook, drag hook is hooked in water outlet joint end face, tie rod afterbody is fixed in water inlet joint, described drag hook comprises the Embedded Division embedding water outlet joint end face, clamping bolt is connected with between Embedded Division and tie rod, described water outlet joint is provided with the tapped hole coordinated with clamping bolt.
Preferably, described tie rod afterbody is fixed with screw rod, spiro rod length direction and pump housing axis being parallel, screw rod is combined with nut, and water inlet joint is provided with the dunnage vertical with screw rod, and dunnage is provided with through hole, screw rod is through described through hole, and described nut is screwed on the screw rod that is positioned at below dunnage.
Preferably, described screw rod is welded on tie rod afterbody, and described tie rod lateral tail is provided with stamping forming a pair depression, and tie rod tail inner side is provided with protruding with a pair that caves in corresponding, and described screw rod is between projection.
Preferably, described projection is kidney-shaped, and projection length direction is parallel with spiro rod length direction.
Preferably, described tie rod has four and is distributed on pump housing circumference.
By adopting technique scheme, achieve following advantage: owing to there being the restriction of clamping bolt, Embedded Division is difficult to deviate from the groove of water outlet joint end face, tapped hole on water outlet joint makes clamping bolt be difficult to transverse shifting, serve the position-limiting action of counter brace, ensure effectively to strain spiral case, ensure the integrity of sealing and structure.
Accompanying drawing explanation
Fig. 1 is structural drawing of the present utility model;
Fig. 2 is the enlarged view at A place in the utility model Fig. 1;
Fig. 3 is the structural drawing of the utility model tie rod;
Fig. 4 is the part-structure figure of the utility model tie rod.
Reference character: 1, spiral case; 2, motor; 3, water inlet joint; 4, water outlet joint; 5, tie rod; 5a, depression; 5b, projection; 6, drag hook; 6a, Embedded Division; 7, clamping bolt; 8, dunnage; 9, screw rod; 9a, nut.
Embodiment
A kind of deep-well pump, comprise the pump housing, motor 2 is provided with bottom the pump housing, it is water inlet joint 3 between motor 2 and the pump housing, pump housing top is water outlet joint 4, the described pump housing forms by some spiral cases 1 are stacking, spiral case 1 inside is provided with impeller, the tie rod 5 straining described some spiral cases 1 is provided with outside the described pump housing, tie rod 5 head is provided with drag hook 6, drag hook 6 is hooked in water outlet and saves 4 end faces, tie rod 5 afterbody is fixed in water inlet joint 3, described drag hook 6 comprises the Embedded Division 6a that embedding water outlet saves 4 end faces, clamping bolt 7 is connected with between Embedded Division 6a and tie rod 5, described water outlet joint 4 is provided with the tapped hole coordinated with clamping bolt 7.Owing to there being the restriction of clamping bolt 7, deviate from the groove that Embedded Division 6a is difficult to save 4 end faces from water outlet, the tapped hole on water outlet joint 4 makes clamping bolt 7 be difficult to transverse shifting, serves the position-limiting action of counter brace 5, ensure effectively tension spiral case 1, ensure the integrity of sealing and structure.
Wherein, tie rod 5 afterbody is fixed with screw rod 9, screw rod 9 length direction and pump housing axis being parallel, screw rod 9 is combined with nut 9a, water inlet joint 3 is provided with the dunnage 8 vertical with screw rod 9, and dunnage 8 is provided with through hole, screw rod 9 is through through hole, and nut 9a is screwed on the screw rod 9 that is positioned at below dunnage 8.By tightening of nut 9a, make tie rod 5 strain spiral case 1 gradually, easy-to-operat and easily regulate rate of tension, dunnage 8 can well be conflicted with the end face of nut 9a simultaneously, better stressed.
Wherein, screw rod 9 is welded on tie rod 5 afterbody, and described tie rod 5 lateral tail is provided with stamping forming a pair depression 5a, and tie rod 5 tail inner side is provided with a pair protruding 5b corresponding with the 5a that caves in, and screw rod 9 is between protruding 5b.When screw rod 9 is welded on tie rod 5 afterbody, if tie rod 5 afterbody does not have protruding 5b, be difficult to screw rod 9 is fixed, solder does not have local absorption yet, and in order to ensure the highly-efficient processing of protruding 5b, directly becomes in tie rod 5 upper punch swaging, saves running cost.
Wherein, protruding 5b is kidney-shaped, and protruding 5b length direction is parallel with screw rod 9 length direction.The protruding 5b of kidney-shaped can form longer area of contact with screw rod 9, better plays firm effect.
Wherein, tie rod 5 has four and is distributed on pump housing circumference.Three just can make tie rod 5 well fix spiral case 1 in theory, but four can be more well-balanced, and firm effect is also better, can alleviate the pulling force of every root simultaneously.
The above is only preferred implementation of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technological schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
