Abstract

The utility model discloses a kind of novel clamp button seal ring structures, it mainly include choma seat, choma, choma lid etc., pump shaft passes through mechanical connection pump head lining, pump head lining connects the pump housing by seal with O ring, pump shaft front end connects impeller, and impeller is tightly connected choma seat by choma, choma lid, the fastening screw as sealing ring.Punching press three openings and bending form three bending openings on the inside of choma lid, are opened on choma there are three the opening matched, the opening of the bending opening insertion choma of choma lid is rotated with limiting choma circumferencial direction with impeller.The utility model limits sealing ring circumferencial direction and rotates with impeller；Reduce impeller and seal the abrasion of interannular, reduce failure rate, reduces the noise that sealing ring is generated with impeller rotation, improve the stability that pump uses；Structure radial dimension is controlled, and is easily installed impeller with the pump housing；Effectively increase the efficiency of pump.

Description

A kind of novel clamp button seal ring structure

Technical field

The utility model relates to the fields of pump, and in particular to a kind of novel clamp button seal ring structure.

Background technique

Pump is the machinery for conveying liquid or being pressurized liquid, it sends the mechanical energy of prime mover or other external energies to Liquid increases liquid energy；Ring assembly is to prevent one kind of liquid reflux hydraulic in the machinery of the trandfer fluids such as pump Element.The similar pump product structure of the current impeller seals ring structure of my company and market is almost the same, choma as sealing ring simultaneously It is fixed by choma lid, mainly has the disadvantages that thickness of sealing ring only 2mm, sealing ring are rotated with impeller, cause impeller and pump Body abrasion, or even rupture；With noise when rotation, the performance and use of pump are influenced；Radial floating space is larger, when installing impeller It is relatively difficult, it is easy to touch and curved breaks sealing ring；Sealing ring axial dimension is too short, is easy failure.

Utility model content

The purpose of the utility model is to overcome the shortcomings of the prior art, and provide a kind of novel clamp button sealing ring Structure.

The purpose of this utility model is completed by following technical solution: this novel clamp button seal ring structure, It mainly include pump shaft, mechanical seal, O-ring, pump head lining, impeller, choma seat, choma, choma lid, the pump housing, pump shaft passes through machine Tool is tightly connected pump head lining, and pump head lining connects the pump housing by seal with O ring, and pump shaft front end connects impeller, and impeller passes through work Choma seat is tightly connected for the choma, choma lid, fastening screw of sealing ring；Punching press three openings and bending on the inside of the choma lid Three bending openings are formed, are opened on choma there are three the opening matched, choma insertion choma seat simultaneously covers choma lid, choma lid Choma is connected and fixed by fastening screw with choma seat, the opening of the bending opening insertion choma of choma lid is to limit choma circumference Direction is rotated with impeller.

The fastening screw is Cross Recess Head Screw.

The utility model has the following beneficial effects: the utility model sealing ring by it is original it is flat be changed to buckle-type, thus Sealing ring circumferencial direction is limited to rotate with impeller；Reduce impeller and seal the abrasion of interannular, reduces failure rate, reduce The noise that sealing ring is generated with impeller rotation improves the stability that pump uses；Structure radial dimension is controlled, make impeller with The pump housing is easily installed；Effectively increase the efficiency of pump.

Description of symbols: pump shaft 1, mechanical seal 2, O-ring 3, pump head lining 4, impeller 5, Cross Recess Head Screw 6, Choma seat 7, choma 8, choma lid 9, the pump housing 10, bending opening 11, opening 12.

Specific embodiment

Detailed introduction is done to the utility model below in conjunction with attached drawing:

Embodiment: as shown in the picture, this novel clamp button seal ring structure mainly includes pump shaft 1, mechanical seal 2, O Shape circle 3, pump head lining 4, impeller 5, choma seat 7, choma 8, choma lid 9, the pump housing 10, pump shaft 1 connect pump head by mechanical seal 2 Lining 4, pump head lining 4 are tightly connected the pump housing 10 by O-ring 3, and 1 front end of pump shaft connects impeller 5, and impeller 5 passes through as sealing Choma 8, choma lid 9, the Cross Recess Head Screw 6 of ring are tightly connected choma seat 7.The 9 inside punching press of choma lid three are open and roll over Bending is opened there are three the opening 12 matched, choma 8 is embedded in choma seat 7 and simultaneously covers choma on choma 8 at three bendings opening 11 Lid 9, choma lid 9 and choma seat 7 are connected and fixed choma 8,11 insertion of bending opening of choma lid 9 by Cross Recess Head Screw 6 The opening 12 of choma 8 is rotated with limiting 8 circumferencial direction of choma with impeller 5, reduces the abrasion between impeller 5 and choma 8, reduces failure Rate simultaneously reduces the noise that choma 8 is generated with the rotation of impeller 5, improves the stability that pump uses.Structure radial dimension is controlled, and is made Impeller 5 is easily installed with the pump housing 10, and pump efficiency is obviously improved, and does not influence the axial motion of impeller 5.

It is understood that it will be understood by those skilled in the art that the technical solution of the utility model and utility model structure Think of is subject to equivalent substitution or change all and should belong to the protection scope of the utility model the attached claims.
