Abstract
A multistate pump bearing box cooling device comprises an end cover, a bearing gland and a rotary shaft. The end cover, the bearing gland and a bearing block form a bearing box. Lubricant is filled in the bearing box. A bearing sleeve is disposed on the rotary shaft. A protruding oil ring is disposed on the bearing sleeve. A fan is disposed at one end of the rotary shaft. A cooling coil is disposed in the bearing box and below a bearing. The multistate pump bearing box cooling device overcomes the defects of poor radiation effect, limited mounting space and the like in the prior art, has the advantages of compact size, high heat exchange efficiency, simplicity and convenience to assemble and the like, and the service lives of pumps and bearings are prolonged effectively.
Description
Technical field
The utility model relates to the bearing housing of pump, relates in particular to a kind of multistage pump bearing housing cooling unit.
Background technique
When multistage pump is pumped high temperature media, owing to the reason of heat transmission causes the temperature of bearing housing parts too high, adding the temperature rise that the load operation of upper bearing (metal) high speed produces is superimposed, tend to exceed the operating temperature that bearing and lubricant oil allows and cause mechanical failure, for fear of the rising of bearing and lubricant oil Yin Wendu and lost efficacy, need cool off bearing housing, with the running temperature of reduction bearing, thus the working life of assurance bearing.Traditional bearing housing oil cooling but mode comprises external cooling method and interior cold mode two classes, and wherein external cooling method mainly contains: at the bearing housing outer surface radiating fin is set, cooling fan is installed outside bearing housing or cooling water chamber etc. is set in bearing housing outside independently.Generally speaking, external cooling method belongs to the indirect type of cooling, and cooling effect is not good, and particularly, for the occasion that pump is pumped high temperature media, external cooling method can not efficiently radiates heat.Traditional interior cold mode then is in the bearing fuel tank cooling coil to be set, interior logical cooling circulating water, and the effect of this type of cooling is better than external cooling method.Yet, because the space is limited in the bearing housing, and needs maintenance lubricant oil reserves as much as possible, so inner coil pipe pipe range can not be oversize, thereby influence cooling effect.
The model utility content
It is a kind of that the purpose of this utility model is to provide
Adopt mechanical agitation cooling, air-cooled and multistage pump bearing housing cooling unit that water-cooled combines.
The utility model is to realize like this, multistage pump bearing housing cooling unit, comprise end cap, bearing gland, rotating shaft, it is characterized in that: described end cap, bearing gland and bearing support are formed bearing housing, be filled with lubricant oil in the bearing housing, rotating shaft is provided with bearing housing, and described bearing housing is provided with the band oil ring of convex shape; One end of rotating shaft is provided with fan; In bearing housing, below the bearing, be provided with cooling coil.
Cooling unit in the utility model has overcome shortcomings such as the conventional art radiating effect is poor, installing space is restricted, and it is small and exquisite to have a volume, and the heat exchange efficiency height assembles advantages such as simple and convenient, has prolonged the working life of pump and bearing effectively.
Description of drawings
Fig. 1 is an embodiment's of the utility model structural representation.
Among the figure 1, fan, 2, end cap, 3, bearing, 4, cartridge housing, 5, the band oil ring, 6, bearing support, 7, bearing gland, 8, bearing housing, 9, cooling coil, 10, rotating shaft, 11, lubricant oil.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing
Multistage pump bearing housing cooling unit, comprise end cap 2, bearing gland 7, rotating shaft 10, it is characterized in that: described end cap 2, bearing gland 7 and bearing support 6 are formed bearing housing, be filled with lubricant oil 11 in the bearing housing, rotating shaft 10 is provided with bearing housing 8, and described bearing housing is provided with the band oil ring 5 of convex shape; One end of rotating shaft 10 is provided with fan 1; In bearing housing, below the bearing 3, be provided with cooling coil 9.
During concrete work, band oil ring 5 is along with rotating shaft 10 is rotated in bearing housing together, fan 1 is also started working, and the cooling medium in the described cooling coil 9 is can be water, and cooling water is recycling, external refrigeration water enters cooling coil 9 from an end, cooling water and lubricant oil 11 carry out heat exchange in bearing housing, flow out from the other end, after a circulatory system again, come back to cooling coil 9 entrances, thereby reach
The effect of mechanical agitation cooling, air-cooled and triple coolings of water-cooled, heat exchange efficiency is improved.
Above-described embodiment be the utility model one of preferred embodiment, those skilled in the art can recognize that according to the disclosed content of the utility model specification the utility model has multiple modification in the process of implementing.In a word, all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., all be included within the protection domain of the present utility model.
