Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is described in further detail:
As shown in Figure 1, Figure 7 shows, a kind of lobe pump mechanical seal installation special tool, including base 1, column 2, movable pressing board
3, threaded post 4, thrust bearing 5, spiral push away 6, mechanical sealing member 7 and right and left rings 8；
Described mechanical sealing member 7 includes rotating ring 71 and rotating seat 73；
As shown in Fig. 2, Fig. 3, Fig. 4, Fig. 5, described right and left rings 8 includes left semi-ring 81 and right semi-ring 82；Left semi-ring 81
One end is flexibly connected with right semi-ring 82 one end；Left semi-ring 81 and right semi-ring 82 coordinate can form an annulus；This annulus is by four
Annulus forms, and is sequentially provided with the first annulus, the second annulus, the 3rd annulus and the 4th annulus from top to bottom, and four annulus one become
Type, the external diameter of four annulus is identical, and d1 ＞ d3 ＞ d2 ＞ d4, wherein d1 is the internal diameter of the first annulus, and d2 is the interior of the second annulus
Footpath, d3 is the internal diameter of the 3rd annulus, and d4 is the internal diameter of the 4th annulus；Wherein by circular arc mistake between the 3rd annulus and the 4th annulus
Cross and as O screens；
As shown in Figure 6, it is the groove of circular arc type that described rotating ring 71 lateral surface the latter half has a cross section；On rotating ring 71
The external diameter of half part and the internal diameter of the second annulus are equal；
Four columns 2 are separately fixed at the surrounding of base 1, and movable pressing board is fixed by four root posts, and base 1 center is provided with
Tapped through hole, thrust bearing 5 is fixedly installed on movable pressing board, the output shaft of thrust bearing and the tapped through hole in threaded post 4
