Analysis of metal electric butterfly valve Electric butterfly valve's request for hydraulic oil?
Analysis of metal electric butterfly valve Electric butterfly valve's request for hydraulic oil:
The vibration principle is to absorb the vibration energy and shock wave brought by electric vehicle vibration through the damping characteristics of hydraulic oil, and then convert them into warm evaporation. Therefore, the quality and viscosity of the hydraulic oil are directly related to the damping force provided and the valve effect of the electric butterfly valve. Therefore, we must make the following pleadings for hydraulic oil.
1. The gasification of hydraulic oil for electric butterfly valve of electric vehicle shall be as small as possible. During the driving of electric vehicle, the hydraulic oil evaporates with the temperature rise. The hydraulic oil with small gasification makes the service life longer and the valve effect better. At the same time, it meets various application environments and has a wide application range.
2. The solidifying point of electric butterfly valve hydraulic oil for electric vehicles is low. The lower solidifying point can enable electric vehicles to run normally in the cold climate in the north, and the common request is lower than - 40 ℃. At the same time, it has good viscosity index and viscosity temperature properties.
3. The valve oil is clean. Clean hydraulic oil can reduce the wear of electric butterfly valve, ensure the valve effect, and improve its service life.
5. The electric butterfly valve oil must have good working stability, anti oil gas mixing stability and anti oxidation stability.
