rotary kiln

Exclusion of foreign matter into the roller axle and tile manufacture and installation of major defects and eliminate the wakou oil wedge is not reasonable, the wakou oil model serious damage to be drawn tile scraping and other serious fault outside, usually by adjusting roller seat displacement to eliminate the heating problem of supporting roller bush.
In the control room temperature or reflect the oil tank temperature exceeds 45 degrees Celsius, maintenance personnel to the scene to determine the specific heating part, heating or heating tile face confirmation. Operation should pay attention to the following methods:
Control adjustment direction: to guide the wheel base adjustment screw with both hands in the field of law, the method is simple and practical for roller holding hands around the finger, little finger, the direction and the direction of rotation of the roller, the index finger and thumb extension, thumb direction wheel moving direction (rotary kiln the axial direction of the roller), the index finger moving direction (radial rotary kiln).
Method of adjusting thrust face fever: when a wheel seat thrust surface heating, can pass into (back) riding wheel seat so that the roller to move along the direction of the center line of kiln to change the clearance of thrust plate and tile eliminate friction heat, this time in order to ensure the center line in the same riding wheel seat adjustment after further adjustment of the supporting roller retaining and inclined to the wheel seat.
Tile surface heating adjustment method: when the support wheel seat tile surface heating, can be through the back wheel seat to make the wheel along the central line of the kiln to move in the direction of the tile to relieve the stress and thus eliminate the heat.
Method of adjusting thrust surface and surface heat simultaneously: when a wheel seat thrust surface heating, can pass into (back) riding wheel seat so that the roller to move along the direction of the center line of kiln to change the clearance of thrust plate and tile eliminate friction heat, this time in order to ensure the center line in the constant adjustment the roller seat, then adjust the gear roller and the roller seat of cable.
Generally speaking, it is not possible to have all the heating phenomena of the 12 supporting wheels, and a group of supporting wheels inside the surface of the two supporting wheels are hot. In order to improve the efficiency of adjustment, a set of supporting wheels can be provided with a thrust pad which is heated and then returned to the supporting wheel seat. If the two supporting wheel block seat are all in or out, it can not alleviate the problem of thrust pad heating. In order to ensure that the central line of the kiln does not change, the two supporting wheels can be adjusted.
Speed adjustment: control of kiln can be stopped for short-term adjustment, but the kiln can be adjusted during normal operation, the kiln speed should be reduced, in general about 1r/m more appropriate, especially Jack the kiln top inward, it is necessary to turn up or slow kiln kiln speed control in 1rp/m.
Control wheel seat shift adjustment: adjustment sometimes should be a supporting base axial block demolition, in order to ensure the accuracy of the adjustment, the adjustment process of each riding wheel seat should use the two indicator, adjustment amount each time between 0.2mm~0.35mm.
Safety control adjustment: adjustment due to loosen the bolt, the kiln may still be running, so the load application of Jack kiln to replace the bolt looseness, due to the adjustment of people, need to continue to observe the roller seat, this time not to fall in the foreign body in the wheel base. Before the adjustment, the adjustment and the adjustment observation, when the hand touches the surface of the wheel seat, attention should be paid to the safety of the oil in the exercise of the body.
Observation and monitoring after adjustment: To observe after adjustment between the thrust plate and the bearing clearance is changed; the same group of roller with another gear wheel and the other in the other two gear roller bearing temperature is abnormal temperature change; stall temperature is adjusted.
The normal operation of the monitoring fluctuations: supporting tile should pay close attention to the end surface of the shaft of supporting wheel, and temperature changes in the operation, hydraulic blocking wheel pressure is appropriate, the roller moves up and down is normal.
