Abstract
The utility model relates to a pump head used on a deep-well submersible electric pump, which provides a split pump head used on a deep-well submersible electric pump with lower material cost, easier control of gas holes and clamping sand and better product stability aiming at the shortcomings of higher material cost, uneasy control of gas holes and clamping sand and worse product stability of an existing pump head used on a deep-well submersible electric pump. The pump head comprises a water outlet body, a water outlet and a connecting piece, wherein the head portion of the water outlet body is provided with a flanging which is inwards bent, and the water outlet is a horn-shaped structure, wherein the connecting piece is a tubular structure, a ring-shaped convex shoulder is arranged on the outer wall of the middle portion of the connecting piece, and screw threads are arranged between the ring-shaped convex shoulder of the middle portion of the connecting piece and the outer wall of the tail end of the connecting piece, the water outlet body is sleeved on the water outlet, the front end of the connecting piece is connected with the tail end of the water outlet body and tail end of the water outlet, and the tail end of the water outlet body, the tail end of the water outlet and the front end of the connecting piece are connected together through a weld joint.
Description
Technical field
The utility model belongs to the water pump field, particularly a kind of pump head that is used on the deep-well Submerged Motor Pumps.
Background technique
The existing pump head that is used on the deep-well Submerged Motor Pumps has two kinds: a kind ofly be and the pump head of the pump housing by being threaded a kind of pump head that to be pump head be connected by tension part with stator.The Placement of these two kinds of pump heads all requires no liquid to ooze dew, the structure of preceding a kind of pump head that is connected with the pump housing has two kinds: a kind of sealing is to seal by screw thread, it is spacing that pump head does not have step, another kind of sealing is that the step on logical screw thread and the pump head and the end face of the pump housing are close to, be end face seal, common formation sealing; Then a kind of structure is a monolithic construction.The existing pump head that is used on the deep-well Submerged Motor Pumps exists that cost of material is higher, pore and folder sand is wayward, the deficiency of the less stable of product.
Summary of the invention
The purpose of this utility model be at existingly be used for that the existing cost of material of pump head on the deep-well Submerged Motor Pumps is higher, pore and folder sand is wayward, the deficiency of the less stable of product, provide that a kind of cost of material is lower, pore and folder sand is easy to control, the stability of product preferably split-type structural be used for pump head on the deep-well Submerged Motor Pumps.
The utility model is to finish by following technological scheme, a kind of pump head that is used on the deep-well Submerged Motor Pumps, it comprises water-outlet body, water outlet and link, the water-outlet body head is provided with the flange that bends inwards, water outlet is horn-like structure, wherein: link is a tubular structure, on the outer wall of link middle part, be provided with annular convex shoulder, annular convex shoulder at the link middle part is provided with screw thread to the outer wall of link end, water-outlet body is enclosed within on the water outlet, the end of the front end of link and the end of water-outlet body and water outlet joins, the end of water-outlet body, the end of water outlet and the front end of link link together by weld seam.
In above-mentioned pump head, be provided with the flange that bends inwards at the end of link.
When the utility model pump head and pump housing assembling, pump head is threaded togather by the screw thread and the pump housing that is located on the link.When pump head is connected with the pump housing, undertaken spacing by the annular convex shoulder that is located on the link.Sealing configuration between the pump head and the pump housing is made of with the annular convex shoulder that is located on the link the screw thread that is located on the link.
The utility model is compared with the existing pump head that is used on the deep-well Submerged Motor Pumps, has that the cost of material is low, and pore and folder are husky easy to control, and the stability of product is characteristics preferably.
Description of drawings
Fig. 1 is the structural representation of the utility model pump head.
Fig. 2 is the structural representation of link.
Embodiment
Contrast accompanying drawing below, the utility model is described in further detail by embodiment.
With reference to accompanying drawing 1 and accompanying drawing 2, a kind of pump head, it comprises water-outlet body 1, water outlet 2 and link 3, wherein: water-outlet body 1 head is provided with the flange 101 that bends inwards; Water outlet 2 is horn-like structure; Link 3 is a tubular structure, is provided with annular convex shoulder 301 on link 3 middle part outer walls, and the annular convex shoulder 301 at link 3 middle parts is provided with screw thread 302 to the outer wall of link 3 ends, is provided with the flange 303 that bends inwards at the end of link 3; Water-outlet body 1 is enclosed within on the water outlet 2, and the end of the front end of link 3 and water-outlet body 1 and the end of water outlet 2 join, and the end of the end of water-outlet body 1, water outlet 2 and the front end of link 3 link together by weld seam 4.
When the utility model pump head and pump housing assembling, pump head is threaded togather with the pump housing by the screw thread 302 that is located on the link 3.
Claims (2)
1, a kind of pump head, it comprises water-outlet body, water outlet and link, the water-outlet body head is provided with the flange that bends inwards, water outlet is horn-like structure, it is characterized in that link is a tubular structure, on the outer wall of link middle part, be provided with annular convex shoulder, annular convex shoulder at the link middle part is provided with screw thread to the outer wall of link end, water-outlet body is enclosed within on the water outlet, the end of the front end of link and the end of water-outlet body and water outlet joins, and the front end of the end of water-outlet body, the end of water outlet and link links together by weld seam.
