The leakage of the hydraulic system refers to the phenomenon that the fluid flowing or temporarily stored in the cavity of the hydraulic component and the system flows out of the boundary of the cavity and flows from the high pressure side to the low pressure side due to pressure, gap and the like. Precision Pressure Gauge The precision pressure gauge can be used to verify the common pressure gauge for industrial use.It can also be used for precise pressure measurement of various non-crystalline and non-solidifying media which is not corrosive to copper alloy and structural alloy steel etc.
The leakage of the hydraulic system refers to the phenomenon that the fluid flowing or temporarily stored in the cavity of the hydraulic component and the system flows out of the boundary of the cavity and flows from the high pressure side to the low pressure side due to pressure, gap and the like.
Hydraulic system leakage is divided into internal leakage and external leakage.
The internal leakage is the leakage of the working medium from the high chamber to the low chamber, such as the leakage of the oil from the high pressure chamber to the low pressure chamber in the hydraulic transmission, and the leakage from the pressure passage in the reversing Valve to the oil return passage.
The external leakage is the leakage of the working medium from the working chamber to the outside of the component and the system, such as the leakage of the end face of the gear pump, the penetration of the hydraulic oil pipe, and the like.
The leakage forms of the hydraulic system mainly include gap leakage, porous leakage, adhesive leakage and power leakage.
The hydraulic transmission uses hydraulic oil as the working medium to transmit power and energy. It has the characteristics of large transmission power, stable movement and convenient control. It is widely used in various fields of modern work.
In hydraulic transmission, the leakage of hydraulic oil is a problem that cannot be ignored. If the leakage is not solved, it will not only affect the working performance of the system, damage the hydraulic components, but also waste resources and cause environmental pollution.
The function of the sealing device is therefore essential for the proper functioning of the hydraulic components and systems. Analyze the failure of the hydraulic transmission seal, take effective measures to control the leakage, and promote the hydraulic technology to play a greater role in the actual work.
The effects of leakage of working media are as follows:
1, will cause the system pressure is not high;
2. The speed of the actuator is unstable;
3, the system is hot;
4. Energy and oil waste;
5, causing control failure;
6. The volumetric efficiency of hydraulic systems and hydraulic components drops sharply;
7. The required working power is not achieved, and the equipment cannot operate normally;
8. External leakage will also cause waste of working medium and environmental pollution, and oil leakage may cause fire.
It can be seen that the importance of hydraulic system sealing, solving and preventing the leakage of hydraulic system has important significance for production and work.
