Abstract
The utility model relates to a special novel centrifugal fan for a nuclear power plant and belongs to the technical field of fan manufacture. The special novel centrifugal fan comprises an impeller mounted in a machine shell, wherein a flow collector communicated with the impeller is mounted in front of the impeller; a motor drive device for driving the impeller is mounted behind the impeller; the motor drive device comprises a motor and a main shaft; one end of the main shaft is connected with the impeller; the other end of the main shaft is connected with a belt wheel; and the motor is connected with the belt wheel through a belt. Due to the structural design of the special novel centrifugal fan, the working efficiency of the fan is improved, the running noise of the fan is reduced, and the fan is small in size, compact in structure and easy to replace and maintain; and an adjusting air valve can be adopted in the air inlet position to adjust the air volume and the air pressure so as to meet the adjustment requirements of different working conditions.
Description
Technical field
The utility model relates to a kind of nuclear power special utility centrifugal blower, belongs to fan manufacturing technology field.
Background technique
AP1000 is the double-loop 1000MW level compressed water reactor nuclear power technology that US Westinghouse company designs and develops.AP1000 adopts the safety system of " non-active " on the basis of traditional compressed water reactor nuclear power technology, be the world's the safest, most advanced existing, nuclear power generating sets through verifying.Centrifugal blower is the important way system constituent element of AP1000 nuclear power, and vital effect is played in the ventilation of nuclear power station.The power that it provides air to carry for the ventilation in each factory building of nuclear power station, different operating zone simultaneously for creating the comfortable working environment of nuclear power station, guarantees that the staff is healthy and avoids radiation and played very important effect.Conventional centrifugal blower is the defective such as bigger than normal and noise height because of contour structure size, no longer has been applicable to the nuclear power station ventilation system.The designing requirements such as, radiation proof little, convenient for installation and maintenance for AP1000 nuclear power ventilation equipment guaranteed performance parameter, size, this case produces thus.
The model utility content
The purpose of this utility model is to provide that a kind of efficient, energy-conservation, low noise, volume are little, compact structure, be easy to the nuclear power special utility centrifugal blower changing and safeguard.
For achieving the above object, the technological scheme that the utility model adopts is:
A kind of nuclear power special utility centrifugal blower, comprise the impeller that is arranged in casing, the place ahead of impeller is equipped with the slip ring (exhaust outlet that is slip ring is communicated with the intake grill of impeller) that is communicated with impeller, and the rear of impeller is equipped with the motor drive unit of drives impeller; Motor drive unit comprises motor and main shaft, and main shaft one end is connected with impeller, the other end is connected with belt pulley, and motor is connected with belt pulley by belt.
Further setting as such scheme is separately installed with front end panel and rear bearing sheet on the front-end face of described casing and ear end face, and casing is arranged on base by front end panel and rear bearing sheet.
Described slip ring is arranged on base by front end panel.
Described main shaft supports by the bearing support that is arranged on bearing bracket, and bearing bracket is arranged on base.
Described rear bearing sheet and bearing bracket are integrally welded.
On described main shaft, and between rear bearing sheet and main shaft, shaft seal is installed.
The described main shaft outside is equipped with spindle protection cover.
The outside of described belt and belt pulley is equipped with belt hood.
Described motor is arranged on the side of bearing bracket.
The utility model is installed in front end panel, rear bearing sheet, bearing bracket on base, makes blower fan be linked to be an integral body.Front end panel and rear bearing sheet all are arranged on casing by bolton simultaneously.
In the utility model, to be rigidly connected, can avoid occurring the rotatable parts that cause because of earthquake and the grazing between static part between the miscellaneous parts such as slip ring and impeller.
Slip ring adopts streamlined curve, and precision-fit between impeller, makes the loss of blower fan air intake reach minimum, improves fan efficiency.
Impeller has adopted high efficiency, low noise Bi-objective optimal design, and characteristic curve of fan is smooth, and the scope of efficiently distinguishing is large.
Main shaft has adopted the alloy structure Steel material, satisfies the blower fan requirement of strength.
In a word, the structural design of a kind of nuclear power special utility of the utility model centrifugal blower has not only improved the working efficiency of blower fan, and the noise that produces when having reduced the blower fan running, and volume is little, compact structure, be easy to change and safeguard.The air intake place can adopt adjusting air valve, to regulate air quantity, blast, reaches the adjusting requirement of different operating modes.
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
