The diamond seal bears the largest load, the most complex working condition and the most associated technical difficulties.
Traditionally, ultra-high strength cast iron is used for manufacturing the diamond seal, so that the necessary strength is ensured, and meanwhile, the cast iron material has higher self-vibration frequency, so that a series of problems caused by vibration coupling of the diamond seal in the sliding process are avoided. In practical use, the hardness of the diamond seal made of the cast iron material is limited, and the key geometric dimension of the diamond seal is changed due to abrasion in long-term use, so that parts of the engine deviate from normal values to cause continuous accelerated abrasion, and finally the engine is rapidly worn or even damaged in a short time after passing a period of stable operation.
The diamond seals at the three top corners of the rotor work under the condition that the diamond seals cannot be well lubricated for a long time, so that the diamond seals are worn prematurely, and the service life of the diamond seals is shortened.
Under various loads and high rotating speed, the radial sealing sheet is not tightly attached to or separated from the inner wall of the rotor chamber and moves in the groove, so that the air chambers are communicated, the working efficiency is reduced, and finally, the waste of fuel is caused.
