Abstract
The utility model relates to a novel double-suction pump, comprising a shaft, bearing bodies, a bearing gland, an impeller, a pump cover, a pump body and assistant sealing elements. The utility model is characterized in that the bearing bodies are arranged at both ends of the pump body, slide bearings are respectively arranged in the bearing bodies, both ends of the shaft are connected with the slide bearings, and the assistant sealing elements are arranged outside the bearing bodies. The utility model has the advantages that the original rolling bearings are changed into the slide bearings, and the slide bearings are lubricated by the liquid conveyed by the pump body; thereby the length of the shaft is largely reduced, the cost is lowered and the reliability and the service life of the pump is improved.
Description
Technical field
The utility model relates to a kind of double suction pump, particularly a kind of novel double suction pump.
Background technique
Existing double suction pump is mainly formed (seeing accompanying drawing one) by bearing support 11, rolling bearing 12, machine sealed cover 13, mechanical seal 14, axle 15, impeller 16, the pump housing 17, pump cover 18, seal 19, bearing gland 20 etc.Because double suction pump adopts mechanical seal, rolling bearing, there is following shortcoming in it: because double suction pump adopts mechanical seal 14, rolling bearing 12, axle 15 is longer, and in the pump operation process, pump operation is not steady, and the life-span is short, poor reliability; Because axle 15 is longer, the amount of deflection of axle is big, and mechanical seal is fragile.
Summary of the invention
The purpose of this utility model is to solve long existing the problems referred to above of double suction pump shaft system in the prior art, and a kind of novel double suction pump is provided.The utility model designs a kind of novel double suction pump, comprise axle, bearing support, bearing gland, impeller, pump cover, the pump housing, secondary seal, it is characterized in that: there is bearing support at the two ends at the pump housing, sliding bearing is arranged in the bearing support, the two ends of axle are connected with sliding bearing, in the bearing support outside secondary seal are arranged.The utility model has the advantages that change rolling bearing into sliding bearing after, the liquid that utilizes pump itself to carry comes lubrication sliding bearing, and the shaft length of pump is shortened greatly, has reduced cost, has improved the reliability and the life-span of pump.
Description of drawings
Accompanying drawing 1 is the prior art constructions schematic representation, and accompanying drawing 2 is a structural representation of the present utility model.
Below in conjunction with accompanying drawing and example the utility model is elaborated.
Embodiment
Comprise axle 1, bearing support 2, bearing gland 8, impeller 3, pump cover 4, the pump housing 5, secondary seal 6 among the figure, it is characterized in that: bearing support 2 is arranged at the two ends of the pump housing 5, sliding bearing 7 is arranged in the bearing support 2, and the two ends of axle 1 are connected with sliding bearing 7, in bearing support 2 outsides secondary seal 6 are arranged.
Owing on existing double suction pump basis, the rolling bearing in the bearing support 11 12 and machine sealed cover 13, mechanical seal 14, bearing gland 20 are removed, change rolling bearing 12 into sliding bearing 7, the liquid that utilizes pump itself to carry comes lubrication sliding bearing 7, thereby axle 1 length of pump is shortened greatly, reduce cost, improved the reliability and the life-span of pump.
