装置に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a rotating machine such as a steam turbine that requires turning operation before and after operation and that requires bearing oil supply.
This invention relates to a pressure booster for a turning device of a rotary machine, which uses low-pressure bearing oil supply, drives a high-pressure oil pump with an oil motor, and utilizes high-pressure discharge oil pressure in order to obtain turning driving force.

複する不経済なものであった。Conventional turning devices for steam turbines used a dedicated electric motor as the drive source, which required a large speed reducer to reduce the speed of the high-speed electric motor, and the motor output was also large. Furthermore, since the steam turbine bearing oil was supplied from an oil supply system using a dedicated electric motor, the turning motor and the turning motor were operated simultaneously, which was uneconomical as the prime mover had to be operated simultaneously.

を用いた。In a steam turbine, turning operation is required for the purpose of preventing the rotating body from being deformed by heat before operation and for the purpose of cooling.The operating speed at this time requires low speed and high torque. Since the dedicated electric motor and the motor for the lubrication system are operated at the same time, the power source for the lubrication system can also be used to reduce the number of equipment, while at the same time using a means of converting to high pressure to generate high torque for turning. .

給油のエネルギーで回転させる。The high-pressure oil V from the discharge pipe 4 is disposed of into two oil guide pipes by the oil distribution valve 5 and guided to two locations in the cylinder 8, respectively, and the reciprocating movement of the piston 9 directly connected to the rack IOK is achieved, resulting in the gear meshing with the rank 10. By rotating the wheel gear 13 fixed to the rotary shaft 14 of the steam turbine 15 via the idle gear 12 from the steam turbine shaft 11, the steam turbine shaft is rotated by the energy of the bearing oil supply.

By converting it into rotational force, it is possible to generate high torque at the low speed required for turning11; it is possible to use the existing bearing oil supply system as is, and it is simple and does not require a dedicated power source for turning. It has the effect of changing Furthermore, the turning speed can be adjusted by adjusting the oil pressure.

を省略させる効果がある。According to the present invention, in a rotating machine such as a steam turbine that requires running before and after operation and also requires oil supply, a part of the oil supply is used to drive an oil pump with an oil motor to provide high pressure. By converting it to hydraulic pressure, it is possible to generate the low speed and high torque required for maneuvering, and the consumption of oil is extremely small, allowing the existing lubrication system to be used as is for maneuvering. This has the effect of omitting a dedicated power source for the purpose.
