Description
Technical field
The utility model relates to a kind of multistage blowers bearing every, sink, belongs to the blower technical field.
Background technique
multistage blowers are in gas compression processes, because of impeller to air work simultaneously gas and impeller, between gas and casing, high-speed friction produces heat, make gas temperature, impeller and casing temperature raise step by step, until impeller and the casing temperature of giving vent to anger rise to the highest, and the progression of blower fan is more, outlet pressure is larger, casing and the outlet side transmission shaft temperature of giving vent to anger is higher, summer, the multistage blower fan casing temperature of giving vent to anger can reach more than 130 ℃, blower fan outlet side axle temperature reaches more than 100 ℃, heat in the blower fan working procedure on casing and axle constantly is delivered on bearing support and bearing, the step bearing temperature of giving vent to anger is raise, the heat of adding the generation of bearing self High Rotation Speed causes bearing temperature rise too high, at high temperature operation can be accelerated the loss of lubricating grease, reduce bearing working life, it is a major reason that causes the fan bearing scaling loss to cause blower fan to damage.In order to solve multistage blowers outlet sides bearing temperature rise problem, the background technique major measure has lubricant oil water-cooling structure, lubricating grease water-cooling structure or adds cooling fan structure in the bearing support outer end, is used for dispelling the heat reducing the temperature of bearing support; The problem that background technique exists is: be air-cooled or water-cooled has all just reduced the temperature of bearing support; Lubricant oil water-cooling structure, lubricating grease water-cooling structure are taked in the bearing cooling of multistage blowers outlet side, and complex structure causes operating cost high, waste water resource; Add cooling fan structure in the bearing support outer end, well do not solve the high temperature of fan shaft to the impact of bearing, effect is not very desirable.
The model utility content
The utility model purpose is to provide a kind of multistage blowers bearing every, sink, the effectively blocking-up multistage blowers heat conduction of casing to the conduction of bearing support heat and blower fan main shaft to bearing of giving vent to anger, improve the working environment of bearing, control multistage blowers outlet side bearing temperature rise solves the problems referred to above that background technique exists.
The technical solution of the utility model is: the multistage blowers bearing is every, sink, comprise radiator, bearing support, bearing, blower fan main shaft and the casing of giving vent to anger, blower fan main shaft is arranged in the casing of giving vent to anger, the end of blower fan main shaft arranges bearing support and the bearing of mutual coupling, be provided with radiator in the casing outside of giving vent to anger, radiator is on the blower fan main shaft of giving vent to anger between casing and bearing support.
Bearing support is made of by several link of boards with flange the bearings part together, flange is fixedly connected with between casing with giving vent to anger, heat transfer area between casing and bearings part has reduced to give vent to anger, match with radiator, guaranteed that the heat on the blower fan main shaft outwards propagated by radiator, the air-flow that is produced by radiator simultaneously has good effect to the heat radiation of bearing support.
The utility model also is provided with thermal insulating pad, is arranged on the position that give vent to anger casing and bearing support are in contact with one another; Thermal insulating pad has been blocked a part by the heat conduction of casing to bearing support of giving vent to anger.
Described radiator is the fan type radiator that the high thermal conductivity metallic material is made, and the heat that blower fan main shaft is passed over sheds, and stops the heat on blower fan main shaft to conduct to bearing, simultaneously bearing support is dispelled the heat, in order to reduce the temperature of bearing.
The utility model also is provided with seal ring, safety enclosure, and seal ring is arranged on blower fan main shaft, and between bearing and radiator, whole bearing support is provided with safety enclosure outward.
The utility model has been installed the fan type high-efficiency radiator that the high thermal conductivity metallic material is made on the transmission shaft between bearing and Balance disc, this radiator not only dissipates the heat that fan shaft outwards spreads out of, and can also take into account bearing support is dispelled the heat.The thermal insulating pad of being made by thermal-protective material of suitable thickness has been installed giving vent to anger between casing and bearing support, has been reduced the conduction heat of casing to bearing support of giving vent to anger.
The beneficial effects of the utility model are: solved blower fan and given vent to anger casing to the bearing support heat transfer problem, stoped the heat of blower fan main shaft to conduct to bearing, improve greatly the working environment of bearing, fundamentally solved the too high problem of multistage blowers outlet side bearing temperature rise; Effectively controlled the temperature rise of bearing, make bearing temperature rise less than 20 ℃, improved to greatest extent the working temperature of bearing, extended the working life of bearing, reduce blower fan and produced the probability of fault because of damage of bearings, simultaneously do not need cooling water and lubricating oil system, reduced operating cost and lubricant pollution.
