In the daily work, we will find that the industrial fan running often occurs suddenly a significant decline in current, Conveyor Idler and belt temperature instantly increased, the entire drive wheel temperature, jitter belt, there will be fine powder drop , Coke paste taste heavy. For this situation, the Conveyor Idler manufacturers from the following aspects of the Conveyor Idler showed a significant increase in the reasons for the temperature:
First, the active wheel and driven wheel are not symmetrical, the same plane on both the larger offset.
Second, the aircraft installed in the fan on the idler is mainly by the Conveyor Idler manufacturers in the manufacture of fans when the synchronous installation up, and the fan of the driven wheel and the drive wheel is not produced by the fan manufacturers, and therefore in the purchase configuration often There will be errors. When the belt is set, the Conveyor Idler groove because it does not meet the belt size or speed, often lead to friction between the two increase, Conveyor Idler and belt serious fever, the final temperature exceeded, resulting in industrial fan failure
Third, the fan of the driving wheel in accordance with the technical requirements of the design and processing. Industrial spin wheel production has a corresponding mechanical design standards. The standard requirements, the Conveyor Idler wheel wheel face does not allow the existence of pores, spokes, wheels, etc. will hinder the Conveyor Idler operation of the depression or shrinkage. At the same time, in order to reduce the Conveyor Idler drive belt work to produce a lot of friction, should be as much as possible to polish the Conveyor Idler surface, reduce the roughness. But may avoid excessive grinding, slippage, and other discomfort.
Fourth, the belt tension does not meet the requirements. Industrial fan belt tension directly affects the belt driven Conveyor Idler work effect. If the belt is too tight, the Conveyor Idler is running hard, the friction increases, the Conveyor Idler and belt heating faster; if the belt is too loose, the Conveyor Idler is easy to slip, causing heat, and ultimately lead to damage to the belt.
Fifth, fan transmission components caused by temperature rise failure. Belt transmission components as an important part of industrial fans, if the overall lack of lubrication on its own, resulting in fan operation is not smooth, the friction will increase correspondingly, the final belt and Conveyor Idler idler, belt failure.
The advantages of the Conveyor Idler drive are: Conveyor Idler transmission can ease the load impact; Conveyor Idler transmission smooth, low noise, low vibration; Conveyor Idler drive structure is simple, easy to adjust; Conveyor Idler drive The manufacture and installation accuracy of the Conveyor Idler is not as strict as the meshing transmission; the idler transmission of the conveyor has the function of overload protection; the two-axis center distance of the Conveyor Idler drive is larger.
The shortcomings of the belt drive are: the Conveyor Idler drive has elastic sliding and slippage, the transmission efficiency is low and can not maintain accurate transmission ratio; Conveyor Idler transmission to the same large circular force, the contour size and the shaft pressure ratio Drive large; Conveyor Idler pulley belt life is shorter.
Large Conveyor Idler, Conveyor Idler Castings Only after the final inspection process can it meet its requirements to meet the requirements, this requirement to be included in the inspection procedures and technical specifications, one of its contents is not allowed on the casting defects Type, degree of occurrence, and even inspection and method are also included in the specification.
According to the large Conveyor Idler, Conveyor Idler casting quality inspection results, usually cast parts are divided into three categories: qualified goods, rework and waste. Qualified refers to the appearance of quality and quality of the quality of the relevant standards or delivery acceptance conditions of the casting; reed refers to the appearance of quality and quality of the quality does not meet the relevant standards or delivery acceptance conditions of the casting, but to allow rework, rework can meet the standard And delivery acceptance conditions of the casting; does not allow rework and rework after still fail to meet the standard and acceptance conditions of the casting.
