Problems solved by technology

[0005] In this Chinese patent document, there are multiple fulcrums on the operating oil pipe in the main shaft, and the distance between each two fulcrums is relatively small, so that the operating oil pipe will not produce large deflection in the main shaft, and the stress on the operating oil pipe is not large , can ensure that the operating oil pipe does not break. However, when the bulb tubular unit is running, the operating oil pipe rotates with the main shaft at high speed. Since there is no lateral support outside the main shaft, the main shaft and the operating oil pipe inside the main shaft will have relative displacement during long-term operation. Directly affect the safe operation of the bulb tubular unit

Abstract

The invention discloses a horizontal supporting device of a bulb turbine unit. The device comprises a supporting rod and a foundation plate connected with a runner foundation, and is characterized in that one end of the supporting rod is connected with a piston device, the piston device comprises a piston cylinder and a ball piston arranged in the piston cylinder, the ball piston is connected with the foundation plate through an elastic ball-shaped supporting base, the other end of the supporting rod is connected with an engine bulb of the bulb turbine unit, and a gap is reserved between the elastic ball-shaped supporting base and the foundation plate. The pretightening effect is achieved through elastic deformation of the elastic ball-shaped supporting base, supporting pretightening force keeps unchanged during long-time operation of the bulb turbine unit, and therefore the bulb turbine unit can safely operate for a long time.

Description

technical field [0001] The invention relates to a bulb tubular unit, in particular to a horizontal support device applied to the bulb tubular unit. Background technique [0002] The generator of the bulb tubular unit is installed in a sealed bulb body that looks exactly like an incandescent bulb. In order to prevent the generator bulb body in the flow channel from swinging left and right, it is necessary to add supports on the left and right sides of the bulb body. [0003] The support structure in the prior art adopts a rigid support, and the stiffness of the rigid support is infinite. Stiffness refers to the ability of mechanical parts and components to resist deformation. The higher the rigidity of the support, the higher the natural frequency. When the natural frequency of the support is much higher than the operating frequency of the equipment, no resonance will occur during the operation, which is called rigid support. Rigid support applied to the bulb tubular unit n...
