Description
Technical field
It the utility model is related to technical field of sealing technology, more particularly to a kind of combination sealing arrangement of water pump.
Background technology
Traditional water pump gland typically has the forms such as packing seal, helixseal, mechanical seal, this several seal form
Respectively there are an advantage and disadvantage, single use sealing property is poor, it is difficult to meets the requirement of modern industry.Water pump is leaked to safety in production band
Carry out hidden danger, while cause unnecessary waste, and seriously pollute production environment, influence the liter up to standard carried out production strictly in line with rules and regulations with enterprise
Level.If operator can not have found in time, it is also possible to cause the damage of pump machine.Therefore, sealing structure is improved, is developed a kind of close
Sealing property is excellent, the novel seal combining structure of service life length is very important.
Utility model content
In order to overcome the above-mentioned deficiencies of the prior art, the utility model provides a kind of combination sealing arrangement of water pump.
The technical solution adopted in the utility model is：A kind of combination sealing of water pump is put, including
Power transmission shaft, screw bearing gland, bearing, the pump housing, outside framework oil seal, gland threaded hole, screwed hole, back-up ring.The pump
Body is divided into the upper and lower pump housing, and the power transmission shaft is connected by bearing with the upper and lower pump housing, and gland spiral shell is provided with screw bearing gland
Trepanning, bearing are provided with screwed hole, twice outside framework oil seal are provided between helicoidal bearing gland and power transmission shaft.
Preferably, it is provided with back-up ring close to bearing side on outside framework oil seal.
The beneficial effects of the utility model：The dual-seal being combined using mechanical seal and outside framework oil seal, is extended
The service life of water pump, the use cost of equipment is reduced, improve the quality of product.In addition, the utility model also has structure letter
Single compact, easy installation and removal, the advantages that favorable sealing property.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure：1. power transmission shaft, 2. screw bearing glands, 3. bearings, 4. pump housings, 5. outside framework oil seals, 6. gland threaded holes, 7.
Screwed hole, 8. back-up rings.
Embodiment
It is further to the utility model below in conjunction with the accompanying drawings in order to be more clearly understood that the technical solution of the utility model
Explanation.
As shown in figure 1, a kind of combination sealing arrangement of water pump, including power transmission shaft 1, screw bearing gland 2, bearing 3, the pump housing
4, outside framework oil seal 5, gland threaded hole 6, screwed hole 7, back-up ring 8.The pump housing 4 divides to be passed through for the upper and lower pump housing, the power transmission shaft 1
Bearing 3 is connected with the upper and lower pump housing 4, and the screw bearing gland 2 is provided with gland threaded hole 6, and the bearing 3 is provided with screw thread
Hole 7, it is provided with twice outside framework oil seal 5 between the screw bearing gland 2 and power transmission shaft 1, it is preferred that close on outside framework oil seal 5
The side of bearing 3 is provided with back-up ring 8, to prevent outside framework oil seal from sliding.
Operation principle：Upper lower pump body is rotated by power transmission shaft band dynamic bearing, screw bearing gland by gland threaded hole and
Screwed hole rotates with bearing.Gap between screw bearing gland and bearing sets twice outside framework oil seal.Twice skeleton
Oil sealing has carried out one of oil sealing and two oil sealings, while adds back-up ring to prevent outside framework oil seal from sliding, and utilizes screw bearing
Gland sealing is again sealed off, and realizes mechanical seal and the combined dual-seal of outside framework oil seal.
The utility model is simple and compact for structure, easy installation and removal, favorable sealing property, and extend water pump uses the longevity
Life, the use cost of equipment is reduced, improve the quality of product.
Described above is only better embodiment of the present utility model, therefore all according to described in the utility model patent application range
The equivalent change or modification done of construction, feature and principle, be included in the utility model patent application range.
