Abstract

A major shaft submerged pump with an impeller having low probability of looseness comprises a slide bearing structure, an impeller fastening structure, a shaft sleeve, a slide bearing, a pump cover and a pump shaft and is characterized in that the slide bearing is provided with a flange structure; and the slide bearing and the pump cover are fixed in the position of the slide bearing flange surface through fastening screws. According to the utility model, a flange structure is arranged on slide bearing, so that the slide bearing and the pump cover are fixed, and then the problem of looseness of the slide bearing due to discontinuous friction force is solved; since the impeller and the shaft are connected through threads, a threaded hole is processed on the end surface of the shaft, an impeller gasket is arranged on the end surface of an impeller hub, and the impeller is fixed on the shaft through a hexagon socket bolt and an elastic gasket, therefore, the problem of looseness of the impeller is solved.

Description

Impeller is difficult for loosening long shaft submerged pump

Technical field

The utility model relates to a kind of long shaft submerged pump.

Background technique

The long shaft submerged pump of using is gone up in industry at present, and amount of deflection is big when having running, under running up; Receive the effect of axial force and radial force; Be prone to cause sliding bearing and impeller stressed and loosening because of being interrupted friction, cause the long shaft submerged pump unstable properties, life time is shorter.

The model utility content

The utility model provides a kind of impeller to be difficult for loosening long shaft submerged pump, and amount of deflection is big in the time of can solving running, and sliding bearing is stressed loosening because of being interrupted friction, and the loosening problem of impeller.

For realizing above-mentioned purpose, adopt following technological scheme:

A kind of impeller is difficult for loosening long shaft submerged pump; Comprise sliding bearing structure, impeller fastening structure, axle sleeve, sliding bearing, pump cover, pump shaft; Said sliding bearing is provided with flange arrangement, and sliding bearing and pump cover is fixed in sliding bearing flanged surface position with set screw.

Said impeller and pump shaft be with being threaded, tapped hole of pump shaft end face processing, and with impeller pad pad at the impeller hub end face, be fixed on the pump shaft with bolt and bullet pad.

The utility model can make sliding bearing and pump cover fix because sliding bearing is provided with flange arrangement, has solved sliding bearing because of being interrupted the stressed loosening problem of friction; Because with impeller and the pump shaft of being threaded, tapped hole of pump shaft end face processing, and with impeller pad pad at the impeller hub end face, be fixed on the pump shaft with hexagon socket head cap screw and bullet pad, solved the problem that impeller becomes flexible.

Description of drawings

According to embodiment and accompanying drawing the utility model is done further explain below.

Fig. 1 is that the utility model is formed structural representation;

Fig. 2 is the utility model sliding bearing structure enlarged view;

Fig. 3 is the utility model impeller fastening structure enlarged view.

Among the figure:

1, sliding bearing structure; 2, impeller fastening structure; 3, axle sleeve; 4, sliding bearing; 5, pump cover; 6, set screw; 7, pump shaft; 8, impeller; 9, impeller pad; 10, hexagon socket head cap screw; 11, bullet pad.

Embodiment

Extremely shown in Figure 3 like Fig. 1; Provided a specific embodiment of the difficult long shaft submerged pump that becomes flexible of the described impeller of the utility model; Among the figure; Sliding bearing 4 is equipped with axle sleeve 3 and is provided with flange arrangement, and in sliding bearing 4 flanged surface positions that sliding bearing 4 is fixing with pump cover 5 with set screw 6, has so just solved sliding bearing 4 loosening phenomenons.Impeller 8 and pump shaft 7 have a tapped hole at pump shaft 7 end faces simultaneously by being threaded, and with impeller pad 9 pads at the impeller hub end face, be fixed on the pump shaft 7 with hexagon socket head cap screw 10 and bullet pad 11.Like this, impeller 8 loosening phenomenons just obtain understanding and determine.

The utility model is simple in structure to be easy to realize, it is stressed loosening because of being interrupted friction to have solved sliding bearing 4 well, and the problem become flexible of impeller 8.

Claims
