Agricultural machine sealing brush
1. It is one of the key technologies for the development of modern advanced turbomachinery. It was originally applied to the aviation industry - aircraft engines.


2. The advantage is mainly reflected in the working condition of the dynamic seal. Since the contact surface of the brush seal and the rotating component is composed of 120 wires per square millimeter, and the wire has a certain inclination angle with the rotating component, this design These filaments act as numerous small springs, effectively avoiding the permanent increase of the sealing gap between the sealing member and the rotating member due to the long-time high frequency and the rotating member being rubbed.


3. Many domestic thermal power plants have adopted such a seal, which provides a safe and convenient way for China to save energy and reduce consumption.
Brush-type seal is a kind of high-efficiency damping seal developed in recent years. Its leakage is 1/5-1/10 of the comb-tooth labyrinth seal, and it allows the transient between the static and the static to be different and keep the sealing ability unchanged. The unit efficiency has improved the stability of the rotor and is one of the key technologies for the development of modern advanced turbomachinery. It has been applied to turbomachinery, industrial gas turbines and steam turbines. In the aviation field, the application of brush seals is an important means to improve the performance of aero-engines. In the technological innovation and development of major turbine companies such as GE and Siemens, brush-sealing technology research is one of the important contents.
