In the shell, turned back again to the first half of the drive end bearing bracket in the rear end that the shell is extended in the shell；The copper
The internal face and outside wall surface of pipe are screwed surface；The excircle of the drive end bearing bracket is connected to the front end of the shell,
The drive end bearing bracket is provided with medium inlet and media outlet, and the medium inlet is located at lower half, and the media outlet is located at upper
Half portion；The middle of the inside of the drive end bearing bracket is provided with lagging, and the lagging divides the inner space of the drive end bearing bracket
It is segmented into the first half and lower half；The first half is in the middle part of the collection of the medium inlet of the copper pipe, and the lower half is described
In the middle part of the collection of the media outlet of copper pipe；The rear end cap is welded in the rear end of the shell, the rear end cap by cylindrical shell and
Spherical calotte is welded, and the cylindrical shell is connected with the rear end of the shell；The spoiler be more than semicircle discount vibram outlet, cloth
It puts mode to arrange along the enclosure proportional spacing for part, the discount vibram outlet of adjacent spoiler is located above and below vertical respectively
Both sides make the runner in the shell form the passage for the turbulent flow that teeters.
Shell of the present invention is relatively thin housing, can not employ the form installation front-end and back-end of bolt or flange
Component, therefore after first welded and installed noseplate and rear bottom plate, it is possible to opened up on noseplate and rear bottom plate bolt hole or
Flange hole is easily installed other component.
