As the main equipment of crushing and sand making production line, impact crusher has been used for a long time. At the same time, it is easy to encounter some failures, such as unstable high-speed operation, which makes users have to s for maintenance. What is the cause?
1. Unbalanced fuel supply. If the speed of the impact crusher reaches speed without load, if the speed continues to increase, the centrifugal force of the flywheel of the adjuster will be too large, which will overcome the tension of the speeder spring and push the tie rod to move the oil supply rack to Oil filling direction. The position of the fuel supply lever is equal to the position of the fuel supply rack at low speed. Therefore, if the oil supply is uneven and the error is too large, it will affect the stability of the operation. 2. The oil-cut time is uneven. If the impact crusher has reached speed when the oil is s ped, the fuel injection pump will automatically cut off the oil. However, if the quality of the delivery valve and plunger components is not the same, or the oil cut-off time is inconsistent due to different wear, it may be that some cylinders are supplied with oil and some cylinders are supplied with a small amount of oil or the oil is cut off very quickly Slow, which will cause the impact crusher to be unstable at high speed.
