In the form of leaks as leakage flow can be divided into leakage and external leakage. Mainly refers to the external leakage of hydraulic oil leaking into the environment from the system, resulting in the hydraulic lines of the hydraulic system, hydraulic valves, hydraulic cylinders and hydraulic pumps external (hydraulic motor); internal leakage is due to the pressure difference between the high and low side presence and a seal failure and other reasons Road mixing machine hydraulic maintenance, the hydraulic oil flow from the high pressure side of the internal system low pressure side, such as hydraulic transmission fluid leaking from the high pressure chamber to the low pressure chamber; and pressure from within the valve to return oil passage leaks and other channels. The main form there is a gap leak leak leak porous, adhesion leakage and leakage power from the point of view road mix hydraulic maintenance costs, the first condition is that the hydraulic system to work within the system must be cleaned. Before the new equipment operation, or a piece of equipment after the overhaul, the hydraulic system is contaminated is unavoidable, the installation process hoses, pipes and fittings that could have contaminants into the system. Even though the new oil also contains some unexpected contaminants. Measures must be taken as soon as the outlet filter pollutants mix hydraulic repair company, otherwise it may malfunction shortly after the device into operation, and failure often very early onset of severe road mix hydraulic service businesses, some components such as pumps, motors There might have been fatal damage. The purpose is to flush the system to eliminate or minimize premature failure of the device. Rinse the goal is to improve the cleanliness, the cleanliness of the system remains within the pollution tolerance key hydraulic components within the system to ensure life road mix hydraulic component reliability and maintenance of hydraulic systems Manufacturers, Xi'an Chengtong hydraulic maintenance, Yan'an Road mixing machine hydraulic service provided by the Xi'an Chengtong hydraulic maintenance Limited.
