Problems solved by technology

[0002] A steam turbine is a rotary power machine that converts steam energy into mechanical work, also known as a steam turbine. It is mainly used as a prime mover for power generation, and can also directly drive various pumps, fans, compressors and ship propellers. Use the exhaust gas or intermediate extraction of the steam turbine to meet the heating needs of production and life. According to the actual needs of the steam turbine, the steam turbine usually needs to be equipped with a regulating device to control the intake of the steam turbine. The traditional device for regulating the steam turbine is generally It uses hydraulic control, but to use hydraulic pressure to achieve the purpose of the control device, a large set of hydraulic equipment is required, which usually occupies a large area. Now there are also some equipment that use electronic control to adjust the air intake of the steam turbine. Through the sensor The combination with PLC achieves the purpose of precise control, but the cost of this kind of equipment is high and the maintenance is inconvenient

Abstract

The invention discloses an adjusting device for a single-cylinder turbine. The adjusting device comprises a base body. A left-right-extending first cavity is formed in the base body. A second cavity is formed below the right side of the first cavity. The upper end wall and the lower end wall of the second cavity are rotationally provided with an up-down-extending first rotation shaft through bearings. The upper end of the first rotation shaft stretches into the first cavity and is fixedly connected with a first belt wheel. The lower end of the second cavity is provided with a rotation motor which is in power connection with the first rotation shaft. The left side in the first cavity is provided with a second belt wheel which is connected with the first belt wheel through a belt. A third cavity is formed below the left side of the first cavity. A second rotation shaft is rotationally arranged between the first cavity and the third cavity through a bearing. The upper end of the second rotation shaft stretches into the first cavity and is fixedly connected with the second belt wheel.
