The invention discloses a grease leakage preventing seal structure of a rotating disk bearing of a fan. The grease leakage preventing seal structure comprises an inner sleeve ring and an outer sleeve ring which are matched together; one or more rows of raceways which can accommodate rolling bodies are arranged between the inner sleeve ring and the outer sleeve ring; seal rings are arranged between the inner sleeve ring and the outer sleeve ring, on two sides of the corresponding raceway; one or more grease discharging holes are formed in the seal rings on one side or two sides of each raceway, and an oil return system is connected to the seal rings on one side or two sides of the corresponding raceway through the grease discharging holes; the oil return system mainly consists of one or more oil guide pipes, one or more oil path control valves and one or more oil collectors; the upstream end of each oil guide pipe is in sealed connection to the corresponding grease discharging hole in the corresponding seal ring, and the downstream end of each oil guide pipe is in sealed connection to the corresponding oil collector; and each oil path control valve is arranged on the corresponding oil guide pipe. Under the premise that the pressure resistance limit of the seal rings does not need to be improved, the grease leakage preventing seal structure disclosed by the invention can be adapted to working conditions of various grease discharging resistances, is good in seal effects, and stable and reliable in running process, and can effectively prevent lubricating grease in the raceways from leaking outwards out of order.

The invention discloses an air-suction type impeller case. The air-suction type impeller case mainly comprises a case shell and an impeller arranged in an inner cavity of the case shell, an inlet communicated with the inner cavity is formed in the outer wall of the case shell, a port, in the inner cavity of the case shell, of the inlet is positioned at the center of the impeller, and an outlet of the case shell is formed in the case shell along a tangential direction of the impeller. The inlet is formed right opposite to the center of the impeller inside the case shell, air pressure at the center of the impeller is low, and negative pressure at the center of the impeller is high, so that the maximum negative pressure position and the maximum rotary air flow position of the rotating impeller can be fully utilized, utilization rate of the air flow is maximized, air inflow suction force at the inlet is maximized, and effective utilization rate of air energy is increased. Meanwhile, the impeller has a function of separating air from other sucked articles, so that other large articles are prevented from being sucked in to wind and block the impeller, the impeller structure is protected under the condition that solid articles are sucked into a fan, and applicable range of the fan is enlarged.

The invention discloses a discharge diversion device for transformer rubber coating machine automatic feeding and discharging. The device comprises a rubber coating machine main body, a rotary table,transformers, a rubber coating fixing base and a material strap support; the rubber coating machine main body is internally provided with a rotary table driving device, the rotary table driving devicedrives the rotary table to rotate through a driving shaft, the rubber coating fixing base is provided with a discharge sliding chute inclining downwards, vertically downwards arranged first fixed rods are fixedly connected to the two sides of the upper end of the discharge sliding chute, second fixed rods are vertically and fixedly connected to one sides of the middles of the first fixed rods, the front ends of the second fixed rods are connected with the bottom of the discharge sliding chute, multiple vertically and fixedly connected third fixed rods are arranged on the other sides of the first fixed rods, and the front ends of the third fixed rods are fixedly connected with the rubber coating machine main body. By means of design of the discharge sliding chute, the transformers obtainedafter rubber coating are completed can be effectively and accurately guided to the set positions, and discharge is more convenient, rapid and orderly.
