Right to be equipped with compression spring, fixinig plate, seal ring of moving ring and the rotating ring successively, the lateral wall of the rotating ring is equipped with several axially extend
Bar shaped inner groovy, be equipped on the right side of the rotating seat madial wall it is several axially extending and with mutual of the bar shaped inner groovy
The bar shaped convex block matched；The stationary ring side wall is equipped with fixed socket, and the machine sealed cover side wall is equipped with and the fixed socket phase
The fixed jack matched, the fixed socket and the fixed jack are inserted with hollow fixed link jointly, in the hollow fixed link
End is equipped with lubricating oil input terminal, is connected with the stationary ring left end face in the fixed socket.
Fixinig plate side is equipped with the opening passed through for the bar shaped convex block.
It is equipped with convex block on the right side of stationary ring, the socket to match with the convex block is equipped on the inside of the machine sealed cover.
Advantageous effect：Using the utility model, when water shortage in pump, lubricating oil input equipment will input lubrication
