How to solve the port of discharge cone crusher unstable
First: the control valve damage. Cone crusher hydraulic system has two control valve block, according to changes in the position of movable cone will be able to judge the state of the control valve. If the moving cone position has not changed, we need to replace the control valve block;
Second: cylinder V-type seal wear. V-ring is mainly used in closed hydraulic oil, hydraulic oil and lubricants isolation. Once the V-shaped seal wear, lubricating and hydraulic oils can lead to mixed, so that the spindle instability. Once the oil level observation can determine if there is no loss of lubricating oil level rise phenomenon occurs, then the V-shaped seal wear, the need for timely replacement of:
Third: hydraulic oil mixed with air. When replacing the cone crusher hydraulic components, hydraulic lines remaining in some of the air, can cause instability lift cylinder. Therefore, after replacing hydraulic components, which must be emptied of residual air;
Fourth: hydraulic line leak. In the cone crusher operation of the process, because of the hydraulic lines and other objects shaking friction leak. Hence the need to strengthen inspection and protection of hydraulic lines of work, if it is found necessary to replace them with new mill leak of.
