Abstract
The utility model relates to a dry-gas seal hygienic self-priming pump, which comprises a motor, a motor housing, a pump seat, a coupler, an air filter, a sealing housing, a pump rear cover, an impeller, a pump front cover, a front cover connector, a compression screw, a pump shaft, a dry-gas seal, an oil seal and a pump leg support, and the dry-gas seal hygienic self-priming pump is also provided with a dry-gas seal for sealing the pump shaft and the pump rear cover, and the dry-gas seal is arranged on the outer side of the pump shaft and between the pump rear cover and the pump shaft. The dry-gas seal hygienic self-priming pump adopts the dry-gas seal structure, since the dry-gas seal belongs to noncontact mechanical seal, not only is the service life long and the power consumption small, but also before the pump is started, the pump is unnecessary to pump, the mechanical seal and the entire pump are not burned under the situation that the idle rotation of the pump caused by the careless operation or the mistake operation leads to the shortage of the fluid medium, and the service life of the pump is greatly prolonged.
Description
Technical field
The utility model relates to a kind of health self-priming pump, and it is specifically related to a kind of dry gas seals health self-priming pump.
Background technique
At present, the axle envelope of existing health self-priming pump all is the contact-type mechanical seal structure, and not only working life is short; Power consumption is big; And before pump is opened, must carry out pump priming to pump, in case careless or operate miss makes pump idle running and lacks flowing medium; Will burn mechanical seal immediately and even whole pump scrapped, so be badly in need of now addressing the above problem.
Summary of the invention
To the problems referred to above, the purpose of the utility model proposes a kind of dry gas seals health self-priming pump.
A kind of dry gas seals health self-priming pump; It comprises: motor, motor outer cover, pump seat, coupling, air filter, sealing cover, pump postoperculum, impeller, pump protecgulum, protecgulum joint, housing screw, pump shaft, dry gas seals, oil sealing and pump foot support; Also be provided with one be used to seal pump shaft and pump postoperculum dry gas seals; Said dry gas seals is located at the outside of pump shaft, and between pump postoperculum and pump shaft.
Said motor is located in the motor outer cover, and motor is fixedly connected with pump seat, and the motor outer cover is fixedly connected with the pump foot support through screw; The transmission shaft of said motor is connected linkage through coupling with pump shaft.
Said pump seat, pump postoperculum and pump protecgulum are sealedly and fixedly connected successively, and said impeller is located between pump postoperculum and the pump protecgulum, is located on the pump shaft through housing screw.
The outside of said dry gas seals is provided with the sealing cover that is used to hold clean gas, and said sealing cover links to each other with screw with pump postoperculum, adopts the oil sealing dynamic seal (packing) between said sealing cover inside and the dry gas seals.
The outer side of said sealing cover is provided with the air filter that is used to filter clean gas.
Said motor outer cover is connected through screw with the pump foot support.
The utility model has the following advantages owing to take above technological scheme:
A kind of dry gas seals health of the utility model self-priming pump adopts dry gas sealing structure, because dry gas seals belongs to non-contact mechanical seal, and long service life not only; Power consumption is little; And before pump is opened, need not carry out pump priming to pump, make pump idle running and lack under the situation of flowing medium in careless or operate miss in a single day; Can not burn mechanical seal and even whole pump, so prolonged the working life of pump greatly yet.
Description of drawings
Fig. 1 is the overall structure schematic representation of a kind of dry gas seals health of the utility model self-priming pump.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is carried out detailed description.
As shown in Figure 1; Be a kind of dry gas seals health of the utility model self-priming pump structural representation; It comprises: motor 1, motor outer cover 2, pump seat 3, coupling 4, air filter 5, sealing cover 6, pump postoperculum 7, impeller 8, pump protecgulum 9, protecgulum joint 10, housing screw 11, pump shaft 12, dry gas seals 13, oil sealing 14 and pump foot support 15; Said motor 1 is located in the motor outer cover 2; Motor 1 is fixedly connected with pump seat 3, and the transmission shaft of said motor 1 is connected linkage through coupling 4 with pump shaft 12.
Said pump seat 3, pump postoperculum 7 and pump protecgulum 9 are sealedly and fixedly connected successively, and said impeller 8 is located between pump postoperculum 7 and the pump protecgulum 9, is located on the pump shaft 12 through housing screw 11.Said dry gas seals 13 is located at the outside of pump shaft 12, and between pump postoperculum 7 and pump shaft 12, is used to seal pump shaft 12 and pump postoperculum 7.
The outside of said dry gas seals 13 is provided with the sealing cover 6 that is used to hold clean gas, and said sealing cover 6 links to each other with pump postoperculum 7 usefulness screws.Said sealing cover 6 outsides are provided with the air filter 5 that is used to filter clean gas.Adopt oil sealing 14 dynamic seal (packing)s between said sealing cover 6 inside and the dry gas seals 13.Said motor outer cover 2 is screwed with pump foot support 15 and is connected.
A kind of dry gas seals health of the utility model self-priming pump adopts dry gas sealing structure, because dry gas seals belongs to non-contact mechanical seal, and long service life not only; Power consumption is little; And before pump is opened, need not carry out pump priming to pump, make pump idle running and lack under the situation of flowing medium in careless or operate miss in a single day; Can not burn mechanical seal and even whole pump, so prolonged the working life of pump widely yet.
The utility model only carries out illustrative with the foregoing description; The structure of each parts, the position is set and connects and all can change to some extent; On the basis of the utility model technological scheme; All improvement and equivalents of individual component being carried out according to the utility model principle all should not got rid of outside the protection domain of the utility model.
