Abstract
The original booster pump bearing body is only provided with one cooling chamber, and moreover, due to the fact that a bearing box body has thicker wall and the heat transfer speed is low, when a medium is at the high temperature, the temperature rise of a bearing is difficult to control within the normal range, thus, the loading capacity of the bearing is reduced, the service life is shortened, the maintenance cost is improved and the equipment stop time is increased. The goals of a high-temperature booster pump bearing body cooling device are achieved through the following measures: a pump shaft is provided with a cylinder roller bearing body and a tapered roller bearing body in sequence; spiral coilers are directly arranged in the two bearing bodies and are soaked in lubricating oil, and cooling water connected with the spiral coilers enters from one end and goes out from the other end, therefore, the cooling problems of the bearing bodies are solved. Shown in a figure I, the bearing bodies (1), the bearings (2) and the lubricating oil which are arranged belong to the original device, whereas the spiral coilers (4) are newly arranged. The high-temperature booster pump bearing body cooling device is mainly used for designing and manufacturing new booster pumps and updating and modifying old booster pumps.
Description
Technical field
The design and the manufacturing of this high temperature front-mounted pump bearing support cooling unit are a kind of improvement of general machinery equipment manufacturing, pump bearing body cooling technology.
Background technique
In the power plant boiler water supply system of forming by feed water pump and front-mounted pump, front-mounted pump needs under the pressure working condition condition about high temperature and 1Mpa more than 165 ℃, conscientiously ensure to the required inlet pressure of water pump, make it reach enough net positive suction heads, thereby ensure to stable, the safe operation of water pump.
The bearing normal working temperature should be controlled at below 80 ℃, otherwise, will cause the reduction of bearing load ability, the lost of life, maintenance cost to improve and the increase of equipment down time.Original front-mounted pump bearing support has only a cooling chamber, cooling water from an end advance, another brings out, the heat of bearing is delivered to bearing support by the lubricant oil in the bearing housing, is delivered to cooling chamber from bearing support again, finally by cooling water the heat of bearing is taken away; Because the bearing housing body wall is thicker, heat transfer is slow, and when medium temperature was higher, bearing was difficult to satisfy usage requirement.In order to meet customer need, will have the bearing support type of cooling now and improve, our high temperature front-mounted pump bearing support cooling unit innovation thinking produces at this point.
Summary of the invention
Former front-mounted pump bearing support has only a cooling chamber, and because the bearing housing body wall is thicker, and heat transfer is slow, when medium during at high temperature, bearing temperature rise is difficult to be controlled at normal range (NR), causes the reduction of bearing load ability, the lost of life, maintenance cost to improve and the increase of equipment down time.
The purpose of this high temperature front-mounted pump bearing support cooling unit is to solve by following measure: under the pressure working condition condition of high temperature and 1～2Mpa more than 160 ℃, we set gradually the bearing support of " roller bearing " and the bearing support of " tapered roller bearing " on pump shaft, by spiral coil directly is installed in two bearing suppories, and be immersed in the lubricant oil, the cooling water that connects spiral coil, one end advances, another brings out, and has solved the cooling problem of bearing support.Because the spiral coil tube wall is thin, heat conduction is fast, tube side is long, area of contact is big, and the heat in the lubricant oil will be taken away rapidly, and too fast, the too high rising of bearing temperature will greatly be alleviated.
Description of drawings
Fig. 1 is the front-mounted pump sectional drawing, and M, N, to locate be the place, position of this bearing support cooling unit; Fig. 2, Fig. 3 are Fig. 1 M, N place, the partial enlarged drawing of bearing support; Wherein: 1 is that bearing support, 2 is that bearing, 3 is that lubricant oil, 4 is spiral coil.
Embodiment
Fig. 2, embodiment illustrated in fig. 3 in, 1-3 is that original device is set; 4 is what newly establish.We are by directly installing spiral coil in bearing housing, and be immersed in the lubricant oil, the cooling water that connects spiral coil, from an end advance, another brings out, because the spiral coil tube wall is thin, heat conduction is fast, tube side is long, area of contact is big, heat in the lubricant oil will be taken away rapidly, and too fast, the too high rising of bearing temperature will greatly be alleviated, and improve the bearing operating mode, prolong bearing working life, produce a desired effect.
The omnipotent front-mounted pump that reaches genco's order of Ma'an Mountain has just adopted this improved bearing support cooling unit, through on probation, meets the demands substantially.
Predominant use to high temperature front-mounted pump bearing support cooling unit: to renewal, the transformation of new front-mounted pump design, manufacturing and old front-mounted pump.
Claims (1)
1. high temperature front-mounted pump bearing support cooling unit, it is characterized by: on pump shaft, set gradually the bearing support of " roller bearing " and the bearing support of " tapered roller bearing ", by spiral coil directly is installed in two bearing suppories, and be immersed in the lubricant oil, the cooling water that connects spiral coil, one end advances, another brings out, and has solved the cooling problem of bearing support.
