Dust and Gas Industry Explosion-proof Brake YWZ5-300/30 Hengyang Heavy Industry Has Coal Safety Certificate.

Typically, internal leaks in large machines occur in the gaps between the internal movements of the hydraulic components. Therefore, we must also be aware that excessive leakage reduces the volumetric efficiency of the pump, the hydraulic cylinders "crawl" and the motor speed is reduced. It is very important to choose the right seal structure and seal material, which is also an important factor in ensuring fluid stability. Contamination and excessive vibration can effectively reduce fluid leakage. Various chemical additives are added to improve the performance of the reducing agent and meet the requirements.

　　And during the working process, due to high pressure and harsh environment, the chemical properties of the fluid will gradually change, exacerbating the oxidation and contamination of the fluid. As a result, the physical properties of the fluid change. If it exceeds the permissible range, the hydraulic system will be damaged. Therefore, the stability of the physical properties of the fluid should be tested regularly.

　　At the same time, hydraulic systems have a certain range of operating temperatures. If the temperature is too high or too low, the physical and chemical properties of the fluid will be greatly affected, which will require a hydraulic effectiveness protection brake to stabilise. The performance of sealing materials and components will also be affected, which will increase leakage and block or impede the movement of components.
