Maintenance And Accident Handling Of Squeeze Flaking Roll Machine
Time:Wed-02-22 hits:
Rolling mill is one of the key equipment of oil plant. It has the characteristics of high price, heavy body and high repair cost. So in the production process, careful maintenance to prolong the service life, which has a very important significance for increasing benefits and reducing costs.After a long period of operation, the wear on both sides of the roller surface often occurs, which affects the effect of rolling embryo. So there should be a specific time each week to use the grinding wheel or other means to sharpen the roller on both sides.
If the oil material debris cleaning is not good, stones, small iron and other impurities into the squeeze flaking roll machine, often cause pitting roller surface, resulting in smooth roller surface pits, rolled out of the material embryo uneven thickness, affecting the oil, then have to replace the press roller, the press roller with pits flat again. The area hardness of the press roll increases, and turning is difficult.
Sometimes the oil material can not be filled in or the oil material can be filled in but can go in very little phenomenon. It will seriously affect the efficiency of rolling mill.
The vibration of the squeeze flaking roll machine is an important reason. The jitter of the pressure roller constantly gives the oil material an upward force, making the oil material thrown up and down by the pressure roller, always jumping up and down between the two pressure rollers. When the oil material does not go into the squeeze flaking roll nachine, the reason should be found out. The smooth roller surface must not be artificially scratched into some pits, so as to increase the friction so that the machine can continue to run.
Broken shaft and roll edge: in order to ensure the requirements of rolling embryo, when the roller flatness gradually increases, it is necessary to increase the spring pressure. This makes the bearing always bear a radial force, once the material flow is not uniform, especially into iron and stone and other hard things, so that the two pressure roller collision, the instantaneous impact force is quite large.
As a result of repeated impact, when the fatigue limit of the shaft is exceeded, the phenomenon of broken shaft or falling edge will occur.
Therefore, it should be emphasized that during operation, the spring regulating the rolling distance should not be too tight, do not enter the iron, the material flow should be uniform and do not break the material, etc., which are all effective measures to prevent such accidents.
We provide a complete set of engineering equipment for plant and animal oil processing, and a complete set of processing equipment such as cooking machines, presses, dryers, crushers, centrifuges, thickeners, evaporators, etc., adopting mature European technology, and provide solutions for construction, installation, commissioning and operation Training.
