How to take care of the parts of coal dryer ?
2016-01-03 16:49
Cyclic loading is pulverized coal dryer equipment mechanical transmission forms a typical load, should maintain a certain relationship between the natural frequency of such changes in the load frequency and fly ash dryer shaft system, when they are same, it will cause the amplitude of the surge shaft, forming destructive resonance. Measures want to solve this problem, there are two ways:
1, changes in fly ash dryer load change frequency strings, for torsional vibration is to change the spindle speed, but the speed of the main parameters of the mechanical properties, one of the periodic variation of fly ash dryer load effect, it the change is bound to affect the performance of pulverized coal machine and dryer use.
2, changing the natural frequency of the drive bearing system, mainly to change the shaft rotational inertia pots and stiffness. Wherein the moment of inertia of the mechanical structure of practice and other relevant, limited magnitude of the changes, the steel of the shaft 4 there is room for a larger increase or decrease. Elastic coupling is to change the stiffness of the shaft system, to avoid the resonance purposes.
Our company coal  machinery and equipment in the production process is very detail-oriented devices, for each component requires strict compliance with national production standards, as long as customers follow the correct guidance for use of equipment and technical personnel, bake the life of the dryer will be longer than similar products.
