Internal leakage of the hydraulic valve body will seriously affect the performance and efficiency of the hydraulic system, so it is crucial to reduce the risk of internal leakage.
First of all, in terms of design, a series of measures can be taken. Reasonably design the internal flow channel of the valve body to ensure that the flow channel is smooth and has no dead angle, reduce the resistance and turbulence of the fluid during the flow process, and thus reduce the possibility of leakage. Optimize the design of the sealing structure and select appropriate sealing materials and sealing forms. For example, use high-performance rubber sealing rings, polytetrafluoroethylene sealing pads, etc. to ensure the reliability of the seal. At the same time, accurately calculate the compression amount and installation size of the seal to ensure that the seal can always maintain a good sealing effect during the working process.
In terms of material selection, high-quality, corrosion-resistant and wear-resistant materials are selected to make the valve body. This can reduce the risk of internal leakage of the valve body due to material aging, corrosion or wear. For the sealing material, it is necessary to select according to the working medium, temperature and pressure of the hydraulic system to ensure that the seal is adapted to the working environment.
Manufacturing process is also a key link in reducing the risk of internal leakage. Strictly control the machining accuracy of the valve body to ensure that the dimensional tolerance and shape and position tolerance of each component of the valve body are within the specified range. For example, the flatness of the valve body's mounting surface, the diameter accuracy of the hole, and the cylindricity directly affect the sealing effect. Use advanced processing equipment and processes, such as CNC machining and precision grinding, to improve the processing quality of the valve body. During the assembly process, it is necessary to strictly follow the operating procedures to ensure that the seals are installed correctly without damage and deformation.
In addition, the use and maintenance of the hydraulic system also play an important role in reducing the risk of internal leakage. Regularly check the working pressure, temperature, flow and other parameters of the hydraulic system to ensure that the system operates within the normal working range. Replace aging and damaged seals and filter elements in time to maintain the cleanliness of the hydraulic oil. Avoid overload operation of the hydraulic system to reduce the impact and damage to the valve body.
In short, reducing the risk of internal leakage of the Hydraulic valve body requires starting from multiple aspects such as design, material selection, manufacturing process, and use and maintenance. By taking a variety of measures in combination, the sealing performance of the Hydraulic valve body can be effectively improved, the risk of internal leakage can be reduced, and the stable operation and efficient operation of the hydraulic system can be ensured.
