Two reasons for Broken machine motor damaged

Composite Crusher Composite short break, is one of crushing production line and sand production line equipment commonly used. Users in the use of composite crusher phenomenon often appear damaged motor, Xin Di composite crusher expert analysis, compound crusher motor damage causes is multifaceted and comprehensive. We go deep into the composite crusher, production site field investigation concluded that fault factors compound Quarry Crusher motor damage because in addition to having in common a general failure of the motor power factor and other equipment, but also with the composite crusher own particular operation generated about . Two reasons for Broken machine motor damage is as follows: 1, pressure automatic switch of reliability and sensitivity, from the compound crusher is usually stopped automatically by the pressure switch (pressure relay) direct drive motor AC contactor automatic control. The automatic pressure switch in most cases, mechanical structure, the use of spring compression and release energy actuator contacts. Maybe automatic pressure switch due to deficiencies or improper regulation of different reasons, such as camera shake effect. 2, the mechanical operation of the Sand Making Machine, electrical control is relatively simple (especially small power type) are generally stand-alone group to work independently, in a non-professional operations where the fault occurred treatment is not timely, relatively speaking, repeated failure expand the rate increase. Compound crusher due to the long work in harsh conditions, exacerbated by the rotor bearing wear. Without rotor crusher would not work, the rotor is irreplaceable in the crusher work. However, it is also easily damaged, switched bearing not only expensive, but also very difficult to replace, often resulting in lost production. How to take effective measures to improve the compound crusher rotor bearing life, the problem in the course of our customers are most concerned about. Normal conditions we need to make more of its attention: First, the choice of bearing rotor to the right choice. Double row radial spherical roller bearings with high load capacity, good aligning performance advantages, so the choice to use more of these bearings as a rotor bearing. In addition, the selection of the bearing life calculation should be based on 5000 ~ 10000h appropriate. Second, to improve the situation by force Quarry Crusher bearings. Acting on the bearing impact load depends on the role of Impulse and support flexibility bearing on the rotor. Flexibility is increased support bearing, will reduce the role of impact load on the bearing. To do this, we can add the proper thickness of rubber plates between the bearing and the support frame to increase the bearing support flexibility. Because added to the rubber sheet, increasing support flexibility to absorb a part of the vibration energy and improve the situation by force of bearings, to extend the service life.
