Any hydraulic component and system require the sealing elements to prevent the leakage of the working medium and the invasion of the external contaminants, such as dust, air, water, and so on. On the surface, the structure and design of the hydraulic sealing elements of the rotary kiln are very simple. However, in fact, they are very complex and precise universal basic components. Henan Hongxing Mining Machinery pay much attention to the latest developments of the hydraulic sealing technology of the rotary kiln to properly select, install and use the sealing elements, which has great significance to prevent the leakage of the hydraulic equipment of rotary kiln. It is good to prevent the pollution and improve the working performance and reliability of the hydraulic equipment. We should pay attention to the following aspects to ensure the normal work of the rotary kiln and the working performance.

There are following requirements.

First, the material of the sealing elements should have good chemical stability in the medium. There should be no swelling, no shrinkage, no softening or hardening.

Second, the material of the sealing elements should have good elasticity and renaturation. The permanent deformation should be small with suitable hardness.

Third, the material should have certain mechanical properties, and the magnitude of the changes of the mechanical properties in the medium should be small.

Forth, the material should be heat-resistant, cold-resistant, wear-resisting and the coefficient of friction should be small.

Fifth, the softness and flexibility to fit with the sealing surface is good.

Sixth, the handling performance of the material should be good and the price should be low.

Henan Hongxing Mining Machinery pay much attention to the latest developments of the hydraulic sealing technology of the rotary kiln to properly select, install and use the sealing elements, which has great significance to prevent the leakage of the hydraulic equipment of rotary kiln. It is good to prevent the pollution and improve the working performance and reliability of the hydraulic equipment. We should pay attention to the following aspects to ensure the normal work of the rotary kiln and the working performance.

First, the sealing device should good sealing performance at a certain pressure and temperature ranges. Second, in order to avoid the chucking of the moving parts or uneven movement of the moving parts, the frictional resistance of the sealing device should be very small and the friction coefficient should be stable. Third, the attrition of the sealing device should be small. The service life of the sealing device should be very long. The sealing device should be compensated automatically to a certain extent. Forth, the structure of the sealing device should be simple with easy assembly and disassembly. Fifth, the material of the sealing elements should be compatible with the working medium.
