Influence of high temperature in summer on hydraulic press
Entering this scorching summer, the high temperature makes people tired, even if they are not working, the sweat will flow down. So what effect does this high temperature have on our hydraulic press? High temperature will also increase the temperature of the hydraulic oil, and if the oil temperature is too high, the following failures and adverse effects will occur:
Entering this scorching summer, the high temperature makes people tired, even if they are not working, the sweat will flow down. So what effect does this high temperature have on our hydraulic press? High temperature will also increase the temperature of the hydraulic oil, and if the oil temperature is too high, the following failures and adverse effects will occur:
①The high temperature of the hydraulic oil will reduce the cleanliness of the oil, increase the leakage, and significantly reduce the volumetric efficiency of the pump and the efficiency of the entire system. As the cleanliness of the oil is reduced, the oil film of the sliding valve and other moving parts is thinned and cut, and the frictional resistance increases, which leads to increased wear, and the hydraulic press heats up, resulting in higher temperature.
②The temperature of the hydraulic oil is too high, which causes thermal deformation of the machine, so that the gap between the moving parts with different thermal expansion coefficients in the hydraulic components becomes smaller and becomes stuck, causing the action to fail, and affecting the accuracy of the hydraulic equipment, resulting in poor processing quality of parts .
③If the temperature of the hydraulic oil is too high, the rubber seals will be deformed, which will lead to premature aging and failure, reduce the service life, lose the sealing performance, cause leakage, and the leakage will further generate heat and temperature rise.
④If the temperature of hydraulic oil is too high, it will accelerate the oxidation and deterioration of the oil, which will cause the precipitation of asphalt substances and reduce the service life of the hydraulic oil. Precipitates block the damping holes and slit valve ports, resulting in failure of pressure regulation, unstable flow of flow valves, stuck directional valves without reversing, metal pipes elongated and bent, and even ruptured and many other faults.
Therefore, when your hydraulic press is unable to press up, the accuracy is inaccurate, and the sealing ring is old and damaged, it may be that the oil temperature of the hydraulic press is too high. You can consider installing an "air conditioner"---cooler for your hydraulic press. .
