Abstract
The utility model relates to a new structure for sealing a water cooling channel of an oil pump, comprising a water channel cover, a water channel, a sealing gasket, a packing gland, a mechanical seal gland cover and a pump cover. The new structure is characterized in that: a fixing ring is provided with an internal thread joggled with an external thread on the pump cover. The new structure has the advantages of pressing by itself without the seal gland cover; and the fixing ring is changed not considering the filler or mechanical seal; the processing and installation are simple and the general degree of the parts is improved.
Description
Technical field
The utility model relates to a kind of new structure that is applied to the waterway sealing of oil pump.
Background technique
Oil pump is because the complexity of its structure, so the scope of using is special occasions such as chemical industry and High Temperature High Pressure mostly, when running into high temperature, the cooling of pump is just extremely important, the cooling chamber of oil pump divides the cooling of pump housing pump cover and the cooling of its bearing suspension part, normally on its structure cooling chamber is set, and cooling chamber need form sealing to it with parts such as chamber lid and chamber lid retaining ring and O type circles, allow cooling water overcurrent circulation inside, reach cooling purpose.Here be exactly the problem that obturator such as cooling chamber lid is installed with regard to relating to a problem, because adopted the sealing of O type circle, so very thin chamber covers the groove that O type circle will be arranged, O type circle also must be with chamber lid fix in position under the state of compression when mounted simultaneously, and then compress chamber lid by parts such as retaining ring and sealing glands, if packing seal mode, difference because of Gland also needs to change chamber lid retaining ring so, so no matter be that the processing of chamber lid or the process of installing are all cumbersome, also may cause part not general because of the difference of sealing, an O type circle sometimes is installed will be damaged several O type circles and just can install the accompanying drawing 1 that concrete structural drawing is seen below.
Summary of the invention:
The purpose of this utility model is to be the problem that difficult installation of oil pump waterway and chamber lid processing bother in the solution prior art, and a kind of new structure that is applied to the waterway sealing of oil pump is provided.The new structure of the waterway sealing that is applied to oil pump is planted in the utility model design, comprise waterway lid, waterway, gasket seal, Gland, mechanical seal cover, pump cover, it is characterized in that: the opening of the waterway on pump cover is coated with gasket seal and waterway lid, has a retaining ring to fix on the waterway lid.It is characterized in that: the outside thread engagement on internal thread and the pump cover is arranged on the retaining ring.The utility model has the advantages that need not sealing gland compresses, can oneself compress need not to consider to be filler or machine envelope and will change retaining ring, processing and simple installation, and can also improve the general degree of part.
Description of drawings:
Fig. 1 is the prior art constructions schematic representation,
Fig. 2 is a structural representation of the present utility model,
Below in conjunction with accompanying drawing and construction embodiment the utility model is made detailed operation instruction.
Embodiment:
Comprise waterway lid 1, waterway 2, gasket seal 3, Gland 4, mechanical seal cover 5, pump cover 6 among the figure, it is characterized in that: the opening of the waterway 2 on pump cover 6 is coated with gasket seal 3 and waterway lid 1, has a retaining ring 7 fixing on waterway lid 1.It is characterized in that: the outside thread engagement on internal thread and the pump cover 6 is arranged on the retaining ring 7.
The sealing of employing flat pad, before waterway lid 1, compress gasket seal 3, reach the purpose of sealing, waterway lid 1 just need not be opened O type ring recess like this, install also more conveniently, the mode that waterway lid 1 usefulness retaining ring 7 and mechanical seal cover 5 are compressed changes the threaded retaining ring 7 of direct usefulness into and fixes simultaneously, so just need not sealing gland and compresses, can oneself compress, need not to consider that filler still is the problem that the machine envelope will change retaining ring 7.Mi Feng effect reaches equally like this, and processing and installation are all easy.Should seal up cooling water, also will simplify processing and easy for installation simultaneously, and can also improve the general degree of part.
Claims (2)
1. the new structure of a waterway sealing that is applied to oil pump, comprise waterway lid, waterway, gasket seal, Gland, mechanical seal cover, pump cover, it is characterized in that: the opening of the waterway on pump cover is coated with gasket seal and waterway lid, has a retaining ring to fix on the waterway lid.
2. by the described a kind of new structure that is applied to the waterway sealing of oil pump of claim 1, it is characterized in that: the outside thread engagement on internal thread and the pump cover is arranged on the retaining ring.
