Kev cuam tshuam ntawm kev kub siab rau lub caij ntuj sov ntawm hydraulic xovxwm
Nkag mus rau lub caij ntuj sov scorching no, qhov kub siab ua rau tib neeg nkees, txawm tias lawv tsis ua haujlwm, hws yuav ntws. Yog li dab tsi cuam tshuam qhov kub siab no rau peb cov xovxwm hydraulic? Qhov kub thiab txias kuj tseem yuav ua rau cov roj hydraulic nce siab, thiab yog tias cov roj kub siab dhau lawm, cov kev ua tsis tiav hauv qab no yuav tshwm sim:

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. .
