Complete equipment of turbine

Abstract

The invention discloses complete equipment of a turbine. The complete equipment comprises a machine body and a first cavity formed in the machine body, wherein a steam outlet cavity which is positioned at the lower end of the first cavity is formed in the machine body; a conveying channel is formed between the first cavity and the steam outlet cavity in a communication manner; a working cavity which is positioned at the left end of the first cavity is formed in the machine body; a steam exhaust channel is formed between the working cavity and the steam outlet cavity in a communication manner;a first transmission shaft which extends left and right is connected to the inner wall of the left end of the first cavity through rotation fit; an impeller box which is positioned in the working cavity is fixedly connected to the tail end of the left end of the first transmission shaft; and a first bevel gear which is positioned in the first cavity is arranged on the first transmission shaft. According to the complete equipment, the structure is simple, operation is convenient, the stress area of impellers and wind is changed, working efficiency is improved, a release device is driven to protect the equipment at the first time through exhaust of gases.

Description

technical field [0001] The invention relates to the technical field of energy and power, in particular to a complete set of steam turbine equipment. Background technique [0002] Steam turbine is the most widely used machine in power conversion equipment at the present stage, and its complete set of equipment consists of air intake device, turning device, cylinder and so on. The cranking device in the existing steam turbine is generally manually monitored or monitored by the computer, and there is a certain delay. If it cannot be disengaged in time when the output shaft is running at high speed, it will cause irreversible damage to the cranking motor and increase maintenance costs. At the same time, the angle of the impeller of the traditional steam turbine is fixed, and it is very inconvenient to replace the impeller group as a whole when the work efficiency needs to be changed. Therefore a kind of barring device that breaks away automatically in real time becomes the writ...

AI Technical Summary

Problems solved by technology

The existing cranking devices in steam turbines are generally manually monitored or monitored by the computer, and there is a certain delay. If the output shaft cannot be disengaged in time, it will cause irreversible damage to the cranking motor and increase maintenance costs.

At the same time, the angle of the impeller of the traditional steam turbine is fixed, and it is very inconvenient to replace the impeller group as a whole when the work efficiency needs to be changed.
