Hengyang Heavy Industry dust gas industry explosion-proof brake YWZ9-200/B30 explosion-proof standard

The causes and reasons for hydraulic fail-safe brake system failures are briefly analysed. The main cause of hydraulic system failure is fluid contamination. Hydraulic failsafe brakes also face this situation. According to statistics, about 70% of hydraulic system failures are caused by fluid contamination. The main cause of contamination is the entry of air into the oil. This is due to poor sealing of pipe fittings, hydraulic pump control elements and actuators, air bubbles in the tank or poor quality of oil. Therefore, this requires a hydraulic fail-safe brake and do not be afraid of oil contamination.

　　If water is mixed into the oil it will turn a milky colour. This is usually caused by moist air leaking into the fuel tank or cooling water. The mixing of solid contaminants can seriously affect the working performance of a hydraulic system. These are accomplished through hydraulic fail-safe brakes that may otherwise shorten the life of the component.

　　And to minimise failures and breakdowns due to fluid contamination, the level of fluid contamination must be kept within the contamination tolerance of critical components. Leaks are a common problem in hydraulic systems. The main causes are worn and damaged seals and loose pipework, which can be detrimental to a hydraulic system. External leaks occur at the mating surfaces of hydraulic components and pipe fittings. Attention should also be paid to this hydraulic fail-safe brake.
