Description

Technical Field

[0001] The utility model belongs to the technical field of turbine equipment, and in particular relates to a new type of turbine actuator with an online leakage detection function. Background Art

[0002] In large and medium-sized TRT and BPRT units operating in industrial production such as steel and chemical industry, all devices equipped with stator blade adjustment actuators, especially the gas turbine actuators of BPRT units, are key devices for realizing automatic adjustment of the units. Because blast furnace gas is dusty and has a temperature of nearly 200 degrees, the actuator shaft head seal frequently ages, breaks and leaks, affecting the stator blade angle adjustment and stable unit operation.

[0003] To check whether the actuator is leaking oil, it is necessary to shut down, open and replace the actuator, and wait until the oil level in the tank changes significantly before checking. If the actuator is not shut down, it is impossible to check for leaks, and leaks cannot be discovered in advance, which brings hidden dangers to the safe operation of the unit and causes waste of power oil leakage. Since the power oil also controls the inlet quick-cut valve, bypass single-acting valve and double-acting valve, and axial flow fan stator adjustment cylinder, it affects the safe operation of the turbine and axial flow blower units, and even causes slow wind and wind interruption accidents in the blast furnace, which in turn causes chemical tuyere accidents.

A connecting flange 2 is provided on the top of the body 1, and the connecting flange 2 is used to fix the actuator in place to ensure a stable connection between the actuator and other components.

[0022] A collection hole 4 is provided at the top of the connecting flange 2, and the collection hole 4 is used to collect the leaked power oil. An annular cavity 6 is provided inside the connecting flange 2, and the annular cavity 6 is a sealed space provided inside the connecting flange 2, and is used to collect and temporarily store the leaked oil. A discharge hole 7 is provided at the bottom of the connecting flange 2, and the discharge hole 7 discharges the oil collected by the annular cavity 6. An oil discharge pipe 8 is connected to the discharge hole 7, and the oil discharge pipe 8 is connected to the discharge hole 7 to discharge the oil, which is convenient for centralized treatment of the leaked oil. An oil discharge valve 10 is provided on the oil discharge pipe 8, and the oil discharge valve 10 controls the opening and closing of the oil discharge pipe 8, which is easy to operate, can control the discharge of oil at any time, and improve maintenance efficiency.

[0023] The following is a detailed description of the design of the above key components:

[0024] The top edge of the connecting flange 2 is provided with a flange hole 3, which is a connecting hole used when installing the connecting flange 2, providing a stable and reliable installation method and facilitating maintenance and disassembly.

[0025] The side of the connecting flange 2 is provided with a reserved hole 5, which is used for possible expansion or installation of other detection equipment, thereby enhancing the scalability and flexibility of the actuator.

[0026] There are several collecting holes 4, which collect the oil that may leak during the operation of the actuator. A plurality of collecting holes 4 are arranged on the top of the connecting flange 2 to ensure full coverage and rapid collection of the leaked oil. The design of the plurality of collecting holes 4 makes the collection efficiency high, and the leaked oil can be collected faster and more effectively. There is one discharge hole 7, and the oil collected by the annular cavity 6 is discharged through a single discharge hole 7. This simplifies the oil circuit design, making the oil collection and discharge more centralized and effective.
