Many users do not pay much attention to the cleanliness of the hydraulic cylinder in the process of using it, so it has encountered obstacles in the process of operation. Anyone with experience should know that it is very important to clean the hydraulic filter element of the hydraulic cylinder.
The hydraulic cylinder pressure filter element is used in the hydraulic system to filter out the particulate debris and rubber impurities in the system to ensure the cleanliness of the hydraulic system. The viscosity of the liquid, the viscosity of the liquid has a great influence on the process of solid-liquid separation. By changing the temperature, the viscosity of the liquid can be reduced, the filtration speed can be increased, and the liquid content in the filter cake can be reduced.
In addition, the incorporation of low viscosity liquids that can be mixed with it can also reduce viscosity. The former method is particularly useful for high-viscosity liquids, such as high molecular weight organic compounds, and is also useful for common liquids, such as water. For example, when water is raised from 20 °C to 50 °C, the viscosity drops by 45%. The latter method is used less. , usually used in petroleum dewaxing. Liquid density, solid-liquid separation operations such as gravity filtration and sedimentation.
It is worth noting that temperature affects the density of liquids, and changes in the amount of dissolved solids can also change the density of liquids. Because the filter cake produced by filtration has a porous structure, there will always be a part of the mother liquor inside. The content of the mother liquor in the filter cake is commonly called the moisture content of the filter cake. %above.
