78. Which parts should be paid attention to during the acceleration of the cigarette machine?
1) It is necessary to pay attention to monitoring the temperature rise in various parts as well as the vibration of the unit. When the vibration of the axes suddenly increases, it indicates that the critical speed of the shaft system has been reached; at this point, the speed should be increased rapidly in order to move past the vibration-sensitive zone. 2) Pay attention to observing the thermal expansion of the unit itself and all the connected pipelines. 3) Monitor any changes in the elastic supports; if there is any sticking, the cause should be identified promptly and adjustments made accordingly.
