Current Position:首页 > News > Dynamic Solution to the heating problem of forging manipulator during operation Date：2017-06-15 15:14:44 Views：
forgingoperating machineThe hydraulic system has always been very hot, especially in summer, when the system heat is even more serious, and the oil temperature can reach about 70"C. As the oil temperature rises, the oil viscosity drops, causing oil leakage everywhere in the system. Moreover, the internal leakage of the pump increases, the volumetric efficiency decreases, and it cannot work. The oil temperature is too high, which greatly reduces the life of the seals. It not only affects production, but also causes a lot of waste of engine oil. In the first half of 1978, we solved the long-standing problem of system heating.
forgingoperating machineThe hydraulic system originally used an "O" type three-position four-way manual reversing valve. When the operating machine completes each action and the manual reversing valve is in the middle position, the high-pressure oil from the main pump returns to the tank through the relief valve (in order to meet the needs of the clamping force, the pressure of the relief valve is adjusted to 120 kg/mm2). In this way, the pump has been working under high pressure since it was started. Only part of the mechanical energy converted from electrical energy has done useful work to make the operating mechanism move, while the rest has been converted into heat energy, causing the oil temperature to rise.
