1. After the smoothing agent is identified, the smoothing agent is sampled and analyzed; whether the turbidity can be mixed with foreign matter or metal powder, etc. This method is especially useful for bearings or large bearings that cannot be closely investigated.
2. It takes a lot of experience to identify the sound through the sound. It is necessary to go through ample practice to be able to identify the sound of the bearing and the non-bearing sound. To this end, the work should be carried out by a person. Listening or listening The rod is attached to the casing to clearly hear the sound of the bearing.
3. The method of identifying the temperature through the operating temperature is a comparative method; it is only used in occasions where the working conditions are not changed. For this reason; it is necessary to record the temperature continuously. When the problem occurs; not only the temperature rises; it also presents irregular changes. .
Second: paper machine bearing correction detailed:
Online correction of paper machine bearings:
In the paper machine bearing using the general smoothing agent, the temperature is abnormally increased, the sensation increases the over-expansion demand and the bearing is replaced; the bearing can be corrected online with the higher-function smoothing agent. The high-performance smoothing agent can be written when the machine is not stopped; Some smoothing agents; after working for a while; will also play a certain correction effect; make the bearing temperature and sensation return to normal; enable the paper machine to work until overhaul; then completely remove and replace the smoothing agent without replacing the bearing. Currently; High-performance smoothing agent with correction function has been presented. For example, the purple crown produced by American Purple Crown Co., Ltd. constitutes a smoothing agent. The online correction of the invalid paper machine bearing can not only reduce the non-scheduling stop; prevent the formation of huge economic losses; and can save a lot of Repair costs and bearing equipment costs.
In order to improve the working rate of the paper machine; reduce the stop outside the program; improve the economic efficiency of the paper mill; when the paper machine bearing wears the general smoothing agent to cause the smoothness and wear failure; can use the high-performance composition smoothing agent with micro-polishing function Online correction. The paper mill can prevent the huge economic loss caused by the non-planned stop; save repair costs and spare parts overhead.
