Abstract
The utility model relates to a bearing dynamic seal structure of single-stage single-suction centrifugal pump, which comprises a shaft, a bearing body, a rolling bearing and a bearing gland. The bearing dynamic seal structure is characterized in that the bearing body at the inner side of the bearing gland is embedded with two lip sealing rings which are arranged reversely and oppositely. The bearing dynamic seal structure has the advantages that the utility model can reduce leakage of dynamic seal and damage ratio of bearing, thereby being beneficial to safe operation and production.
Description
Technical field
The utility model relates to the bearing movable sealing structure of a kind of bearing seal structure, particularly a kind of single stage single suction volute pump.
Background technique
Lubricated significant for the proper functioning of rolling bearing, the oiling agent in the bearing not only can reduce the power consumption that rubs, and reduces wear rate, also plays cooling heat dissipation simultaneously, reduces contact stress, prevents dust, prevents effects such as corrosion and absorption vibration.So what do Lubrication of Rolling Contact Bearing well effectively is the assurance that equipment runs well, but the used rolling bearing of more existing single stage single suction volute pumps is lubricated with machine oil, because the motive sealing of bearing housing is to seal (see figure 1) with felt, the lubricating oil leakage of rolling bearing when operation is very serious, not only cause machine oil to waste in a large number, rolling bearing burns out, and befouling environment, is unfavorable for the safe operation of equipment and carries out production strictly in line with rules and regulations.
Summary of the invention
The purpose of this utility model is that the bearing motive sealing that solves single stage single suction volute pump in the prior art seals the very serious problem of existing lubricating oil leakage with felt, and a kind of bearing movable sealing structure of single stage single suction volute pump is provided.The utility model designs a kind of bearing movable sealing structure of single stage single suction volute pump, comprises axle, bearing support, rolling bearing, bearing gland, it is characterized in that: be embedded with lip-type packing on the bearing support of bearing gland inboard.The lip-type packing that is embedded with on the bearing support of bearing gland inboard has two, and two lip-type packings are oppositely placed.The sealing lip of two lip-type packings of oppositely placing is opposing.The utility model has the advantages that motive sealing leakage and damage of bearings rate obviously reduce, help the safe operation of equipment and carry out production strictly in line with rules and regulations.
Description of drawings
Accompanying drawing 1 is the prior art constructions schematic representation,
Accompanying drawing 2 is the structural representation of the single lip-type packing of usefulness of the present utility model,
Accompanying drawing 3 is the structural representation of two lip-type packings of usefulness 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, rolling bearing 3, bearing gland 4 among the figure, it is characterized in that: on the bearing support 2 of bearing gland 4 inboards, be embedded with lip-type packing 5.The lip-type packing 5 that is embedded with on the bearing support 2 of bearing gland 4 inboards has two, and two lip-type packings 5 are oppositely placed.The sealing lip 6 of two lip-type packings 5 of oppositely placing is opposing.
The direction of lip-type packing 5 sealing lips 6 will be towards the position of sealing, if promptly mainly be for oil sealing, sealing lip 6 should inwardly face toward rolling bearing direction (Fig. 2).If mainly be in order to prevent that foreign object from immersing, then sealing lip 6 should be carried rolling bearing 3.For the effect that can further improve motive sealing is carried out motive sealing with two lip-type packings 5, as Fig. 3, two lip-type packings 5 are oppositely placed, i.e. oil sealing prevents that again foreign object from immersing.Felt oil seal is being changed into lip-type packing 5 oil sealings, preferably handle through surface hardening the diameter of axle and lip-type packing 5 contacting points, and with the enhancing wear resistance, otherwise lip-type packing 5 can increase leakage rate because of wearing and tearing.
Claims (3)
