Abstract
The utility model relates to an improved boiler feed water pump sliding bearing, consisting of a pump shaft, a bearing end cover, a bearing cover, a sliding bearing, a dust proof disk, a cooling chamber, a lubricating oil chamber, and an oil ring. The device is characterized in that the external circumference surfaces of the two ends of the sliding bearing are arranged with an internal groove respectively. The utility model has the advantages that without changing the former structure, the oil leakage problem can be solved effectively only with two grooves arranged on the pump shaft.
Description
Technical field
The utility model relates to the sliding bearing of a kind of bearing structure, particularly a kind of improved boiler feed pump.
Background technique
Structure at existing high pressure water feeding pump for boiler sliding bearing is the middle open type sliding bearing, be up and down bearing cap and bearing support, the centre is bearing (ball) cover, dustproof dish and pump shaft, there is following shortcoming in this structure: reach under the suitable situation of requirement and oil level in part processing and assembling, at pump shaft and dustproof dish, leakage of oil appears between dustproof dish and the bearing (ball) cover, and only leakage of oil when pump operation.Its main cause is because pump shaft and sliding bearing when relatively rotating, form oil film between rubbing surface, again because the rotor part of pump exists the adsorption force of axial float and pump shaft oil when rotating greater than centrifugal force, thereby cause oil film to extend to the two ends of bearing direction along pump shaft, add pump shaft and bearing (ball) cover, there is very big gap between dustproof dish and bearing (ball) cover, therefore when oil film is run into dustproof dish, forms oil droplet and cause leakage of oil.
Summary of the invention
The purpose of this utility model is the problem that solves sliding bearing generation leakage of oil in the prior art mesohigh boiler feed pump, a kind of sliding bearing that can effectively prevent the improved boiler feed pump of pump shaft end leakage of oil is provided, the sliding bearing of the boiler feed pump of the utility model design improvement, comprise pump shaft, bearing (ball) cover, bearing cap, sliding bearing, dustproof dish, cooling chamber, oil chamber, oil ring, it is characterized in that: on the pump shaft circumferential surface in the outside at sliding bearing two ends, respectively offer an inner groovy.The utility model has the advantages that under the situation that does not change original structure only processing twice groove just can effectively solve the leakage of oil problem on pump shaft.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Embodiment
Comprise pump shaft 1, bearing (ball) cover 2, bearing cap 3, sliding bearing 4, dustproof dish 5, cooling chamber 6, oil chamber 7, oil ring 8 among the figure, it is characterized in that: on pump shaft 1 circumferential surface in the outside at sliding bearing 4 two ends, respectively offer an inner groovy 9.
Owing on pump shaft 1 circumferential surface, respectively offer an inner groovy 9 near the outside at sliding bearing 4 two ends, therefore after pump shaft 1 rotates, because of oil ring 8 gets rid of the lubricant oil in the oil chamber 7 on pump shaft 1, lubricant oil extends with the oil film form outward along pump shaft 1, after lubricating oil oil film ran into stopping of inner groovy 9, oil film gathered the formation oil droplet at inner groovy 9 places.Because the centrifugal force during pump shaft 1 rotation that oil droplet is subjected to is got rid of go back to oil chamber 7 greater than adsorption force, can prevent that lubricant oil from exosmosing, and solves the problem of leakage of oil.
Claims (1)
