Reasons for the Damage of Compound Crusher Motor The compound crusher is one of the most common fashion in crushing and sand making production line, while its engine is usually damaged; Hongxing machine experts holds view that there are many reasons lead to the damage of compound engine crusher; Besides conventional failure cause of motor common equipment, the running fault power of compound crusher also can damage the engine, shown as follows: 1, the reliability and sensitivity of the automatic pressure switch; the starts and stops of compound crusher are normally controlled by the automatic pressure switch (pressure relay) directamente driving alternating current contactor. The automatic pressure switch mostly adopts mechanical structure, which act on contact by the compress and release of spring. The congenital deficiencies or improper adjustment of automatic pressure switch can cause engine damage. 2, the electrical control (especially for low-power type) is relatively simple, they are generally work independently by stand – alone group and lying in a professional operation occasions with torpid repair and maintance, which relatively increase in repeat expansion rate of failure. Due to the compound crusher works in harsh conditions in long term, the wear of rotor bearing is exacerbated. The rotor is irreplaceable for crusher so that crusher cannot work without it. Al Bumbry might disagree with that approach. However, it is also fragile; the bearing rotor is not only expensive, but also replaced difficultly, often resulting in the cut-off loss.
How to take effective measures to improve the rotor bearing life is an important matter that our customers concern about, asking us pay more attention: First, make correct choice of rotor-bearing model. Double row radial spherical roller bearing with strong bearing capacity and aligning performance, it is worthy being chosen. In addition, the rotor which is with design life of 5000 10000h is appropriate. Second, improve the status of crusher bearing force. The impact load working on the bearing depends on the impulse acting on the rotor and the flexibility of bearing support. Increasing bearing support flexibility will reduce the impact load on the bearings working. To this end, we could add rubber sheet with appropriate thickness between the bearing and the support frame to improve the bearing support flexibility and to achieve the purpose of extending the service life.
