Causes of abnormal oil pressure and oil temperature of crusher

When the oil circuit or oil pipe of the thin oil lubrication system in a large cone crusher is blocked, it is easy to cause the oil pressure and oil temperature to rise at the same time (when the return oil pipe is blocked, oil leaks from the water dust prevention device, causing oil in the water seal drainage, but the oil pressure does not rise), and the machine needs to be stopped to eliminate the fault; when the eccentric sleeve is partially faulty, the oil temperature is greater than 55℃, and the oil pressure does not rise, the machine should be stopped to eliminate the straight bushing and cone bushing faults;

When the filter is blocked, the oil pressure of the front and rear oil pipes is different. If the oil pressure difference is greater than 0.04MPa, the oil can be supplied without the filter first, and then the filter can be disassembled and cleaned, but the direct oil supply to the crusher should be less than 2-3h;
When the oil temperature is low, the oil switch is not opened properly, and the oil pump is not running well, it will cause no oil flow in the oil indicator. Although the oil pump is running, the oil pressure is less than 0.05MPa. It is necessary to heat the oil, open the oil switch, and repair or replace the oil pump;
In winter, when the oil temperature is too low, the safety valve fails or the oil pump capacity is too large, and the oil supply pressure is too high, the crushing cone will be lifted. The oil should be heated, the safety valve should be adjusted, or the oil pump should be replaced;
When the bearing, bushing, sleeve, bevel gear and other parts fail, the ambient temperature is too high, there is no cooling water, the cooling water pressure is low, or the cooler is blocked, causing the oil temperature to be greater than 60℃, the machine should be stopped to eliminate the fault, and cooling water should be supplied, the cooling water pressure should be increased, or the cooler should be cleaned.
