Into 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；Institute
The internal face of copper pipe is stated to be smooth, outside wall surface is screw thread；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 excircle of the rear end cap is plugged in the rear end of the shell by bolt installation, in institute
It states and gasket is provided between rear end cap and shell；The spoiler is the discount vibram outlet more than semicircle, and arrangement is partly along institute
It arranges with stating enclosure proportional spacing, the discount vibram outlet of adjacent spoiler is located at the horizontal left and right sides respectively, makes in the shell
Runner formed left and right snake-like swing passage.
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.
