Abstract
The utility model relates to a fan cooling mechanical seal bearing structure, which comprises a pump shaft, a shaft sleeve, a pump cover, a mechanical seal, a bearing and a bearing suspension, wherein the shaft sleeve is sleeved on one side of the pump shaft, the pump cover is arranged on the shaft sleeve, the mechanical seal is arranged between the pump cover and the shaft sleeve, the bearing is sleeved on the other side of the pump shaft, the bearing suspension is arranged on the outer sides of a bearing cover and the bearing, the pump cover is connected with the bearing suspension, and the bearing cover presses the bearing and the bearing suspension. The fan cooling mechanical seal bearing structure is characterized by further comprising a fan sleeved on the pump shaft between the pump cover and the bearing cover. The fan cooling mechanical seal bearing structure has the advantages of simple structure, improvement of reliability and stability of a pump, reduction of the temperature of the bearing and the mechanical seal, and prolonged service life.
Description
Technical field
The utility model relates to the parts in the water pump, particularly a kind of fan cooled machine envelope bearing structure that is applied in the water pump.
Background technique
Water pump can produce a large amount of heats when work, shorten the working life of pump.At present, in order to address the above problem, often adopt the method for external cooling water.But, in the industrial environment of complexity, the time regular meeting the slightly high or inconvenient situation in external water source of fed sheet of a media appears, at this moment just can not adopt the method for water-cooled.In view of the foregoing, the staff must propose a kind of novel Coolers envelope bearing structure at those with the inconvenient situation of water-cooling method.
Summary of the invention
The purpose of this utility model has provided a kind of fan cooled machine envelope bearing structure, has solved the deficiencies in the prior art.
The utility model is achieved in that a kind of fan cooled machine envelope bearing structure, comprise: pump shaft, pump shaft one side are with axle sleeve, mechanical seal is arranged between pump cover, pump cover and the axle sleeve, are with the bearing suspension that the outside of bearing, bearing gland and bearing is provided with at the pump shaft opposite side having on the axle sleeve, wherein, described pump cover is connected with the bearing suspension, bearing gland is pushed down bearing and bearing suspension, its feature in: also comprise a fan, on the pump shaft between pump cover and the bearing gland, be with fan.
Described fan adopts engineering plastics.
Described fan and pump shaft are interference fit.
The utility model has the advantages that: simple in structure, the reliability and stability of raising pump, the temperature of reduction bearing, mechanical seal prolongs its working life.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Below in conjunction with drawings and Examples the utility model is elaborated.
Embodiment
Among the figure, a kind of fan cooled machine envelope bearing structure, comprise: pump shaft 1, pump shaft 1 one sides are with axle sleeve 2, mechanical seal 4 is arranged between pump cover 3, pump cover 3 and the axle sleeve 2, are with the bearing suspension 7 that the outside of bearing 5, bearing gland 6 and bearing 5 is provided with at 1 opposite side of pump having on the axle sleeve 2, wherein, described pump cover 3 is connected with bearing suspension 7, bearing gland 6 is pushed down bearing 5 and bearing suspension 7, its feature in: also comprise a fan 8, on the pump shaft 1 between pump cover 3 and the bearing gland 6, be with fan 8.
Described fan 8 adopts engineering plastics.
Described fan 8 is an interference fit with pump shaft 1.
When the pump shaft high speed rotating, drive the fan of being located on the axle and make high speed rotating, on fan, circumferentially be furnished with blade, blade causes flowing fast of surrounding atmosphere, forms wind, utilizes wind to come the mechanical seal and the bearing of cooling fan both sides, reduce the temperature of bearing, mechanical seal, prolong its working life.
Below only expressed mode of execution of the present utility model, it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model patent scope.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
The utility model advantage is: simple in structure, and the reliability and stability of raising pump, the temperature of reduction bearing, mechanical seal prolongs its working life.
