Connecing, the other end is fixed with described top cover by nut.
Further, described connecting rod has 4.
Further, described push rod is top bolt, may pass through the screwed hole of centre of described top cover to described
The precession of La Gai direction.
Further, described push rod is jack.
Further, lid is drawn to be connected with the described ring that is connected by screw described in.
This utility model has the advantage that with good effect:
1, this utility model uses two semi-circular shape to draw lid to impeller wheel back of the body force, impeller uniform force
And lifting surface area is big, will not deform damage；
2, La Gai is to utilize impeller dorsal part gap to dismantle, need not be threaded on impeller hole or its
It is for the non-locating hole of dismounting；
3, using top Bolt dismantling impeller, impeller stress is steady, and be not hit power, it is not easy to causes
Impeller failure；
Can be replaced hydraulic jack when 4, not using top bolt and be placed between pull bar and top cover force.
5, semi-open type or double shrouded wheel it are applicable to, applied widely.
