Description

Technical Field

[0001] The utility model belongs to the technical field of hydraulic filters, and particularly relates to a hydraulic filter with a temperature measuring structure. Background Art

[0002] Hydraulic filters are an indispensable component in hydraulic systems. Their main function is to filter out pollutants from hydraulic oil, including solid particles, moisture, air and other harmful substances, to protect system components from wear, extend the service life of the hydraulic system and maintain its stable operation. During use, the hydraulic oil will increase in temperature due to changes in pressure and other conditions. The operating temperature of the hydraulic oil has a direct impact on its viscosity, which is an important parameter to ensure the normal operation of the hydraulic system. Overheating of the hydraulic system may cause the hydraulic oil to age and deteriorate rapidly, affecting the lubrication effect. In severe cases, it may also damage seals and other components. Most common hydraulic filters only have a single impurity filtering function and cannot detect the temperature of the hydraulic oil during circulation. As a result, when the hydraulic oil temperature is high, it affects the normal operation of the hydraulic system. In addition, the service life of the filter element of the hydraulic filter will be reduced under high temperature, which is not conducive to the use of various components of the entire hydraulic system.

[0003] In summary, the hydraulic filter without a temperature measuring structure has some problems in use, so it is hoped to propose a new structure to solve the above technical problems. Utility Model Content
