First, the multifunctional crusher uses a motor directly connected crushing device, if it is not well connected during the assembly process, it will cause the overall vibration of the multifunctional crusher.
1, The motor rotor and the multi-function grinder rotor different heart. The position of the motor can be moved left or right, or the foot of the motor can be padded to adjust the concentricity of the two rotors.
2, Multi-functional grinder rotor different heart. The reason is that the two supporting surfaces of the rotor shaft are not in the same plane. The copper sheet can be placed on the bottom surface of the supporting bearing seat to ensure that the two shaft heads are concentric.
3. The vibration of the crushing chamber is large. The reason is that the connection between the coupling and the rotor is different or the quality of the crushing hammer is not uniform. The coupling between the coupling and the motor can be adjusted by the corresponding method: when the quality of the hammer is uneven, each group of hammer must be re-selected, so that the relative weight of the hammer error is less than 5 grams.
4, The original balance is destroyed, or the motor must be repaired after the dynamic balance test to ensure the overall balance.
5, Multi-functional crusher anchor bolt loose or foundation is not strong, in the installation or maintenance, to evenly tighten the anchor bolt, between the anchor foundation and the crusher, to install a shock absorber to reduce vibration.
6, Hammer broken or crushed indoor hard debris. These will cause the rotor rotation imbalance, and cause the vibration of the whole machine. Therefore, it is necessary to check the hammer with severe wear regularly. When replacing, replace symmetrically.
7, The connection between the crusher and other auxiliary equipment is not consistent. For example, improper connection of the feeder, feed pipe and discharge pipe will cause vibration and noise.
2. Bearing overheating
Bearing is a more important part of the crusher, and its performance directly affects the normal operation and production efficiency of the equipment. During the operation of the equipment, the user should pay special attention to the temperature rise of the bearing and the noise of the bearing part, and the abnormal should be dealt with as early as possible.
1. The bearing seat is uneven, or the motor rotor is different from the crusher rotor, which will cause the bearing to be impacted by additional load, resulting in overheating of the bearing. In this case, it is necessary to immediately stop the fault to avoid early damage to the bearing.
2, Too much lubricating oil in the bearing, too little or aging is also the main cause of bearing overheating and damage, therefore, according to the requirements of the time and quantity of lubricating oil, general lubrication accounts for 70%-80% of the bearing space, too much or too little is not conducive to bearing lubrication and heat transfer. The bearing extends its service life.
3, The bearing cover with the shaft is too tight, the bearing with the shaft is too tight or too loose will lead to the bearing overheating. Once this problem occurs, there will be a grinding sound and obvious swing in the operation of the equipment. Stop the machine and remove the bearing. Trim the friction area and reassemble as required.
