　　With the rapid development of industry, more and more hydraulic transmission systems of longitudinal mechanical equipment are used, and the phenomenon of hydraulic oil suffering from particles is common. At the same time, in the process of mechanical operation, there are also oil leakage, oil temperature change, particle pollution and other factors. In order to give full play to the best mechanical efficiency, provide the service life of hydraulic system of mechanical equipment such as Slitter, etc The user of the mechanical equipment of the manufacturer shall take effective maintenance measures for the hydraulic system of the slitter and other mechanical equipment. So how can we maintain the rigid hydraulic system? First of all, it is necessary to select an equipment oil filter that can effectively filter the hydraulic oil, so that the hydraulic oil can be reused and filtered. Cost savings.

　　Explanation of oil filter principle:

　　The vacuum oil filter adopts the function of four-stage filtration, dehydration and degassing. First, the oil to be treated is inhaled under vacuum negative pressure, and then enters the infrared carbon fiber heater for preheating after passing through the stainless steel primary magnetic filter and the secondary nano molecular filter. When the temperature is heated rapidly from low to high, the oil molecules begin to decompose inside, and then enter the tertiary coalescing vacuum oil-water separation filter, which adopts the oil-friendly and hydrophobic coalescing separation The first time of oil-water decomposition is carried out according to the characteristics of the filter material at the mouth. The larger water molecules are separated by the coalescing filter element and enter the water storage tank. The micro water and oil molecules enter the vacuum separation tank from the distributor, forming a short layer of film atomization. After the continuous operation of the reactor, the three-dimensional and multi-layer evaporation structure is formed in the tank. Through continuous circulation, the purification purpose can be achieved. Finally, a filtration cycle is completed through the fourth stage polymer fine filter element.

　　Explanation of the principle of the hydraulic system:

　　The hydraulic system is a complete set of device which uses the oil as the working medium, uses the pressure energy of the oil and controls the hydraulic actuator by controlling the valve and other accessories. The quality of a hydraulic system depends on the rationality of system design, the performance of system components, the pollution prevention and treatment of the system, and the last point is particularly important.

　　Protection measures for hydraulic system:

　　1. The oil tank shall be sealed and dustproof, or the breathing hole with air filter shall be arranged;

　　2. In the process of storage and transportation of refined oil, it must be dustproof and waterproof;

　　3. The system must be equipped with filtering device to clean the contaminated particles in time. It is better to accept the filter with indication signal, and the magnetic catcher is better placed at the bottom of the oil tank;

　　4. Place and regularly check the common clearance of the pump, valve, cylinder and other components in the system. If it is too large, repair and adjust it. Alert the system for leakage and wash the strainer inhaled by the pump;

　　5. Add a protective cover at the seal of oil cylinder and push rod, or blow to prevent dust;

　　6. Under normal conditions, the pressure of oil pump shall be adjusted to the minimum to eliminate energy consumption and be on alert.
