Screw conveyor operation and maintenance requirements

Screw conveyor is used for conveying powder , granular, small block materials, general-purpose transportation equipment, all kinds of bearings are in the dust in the work , so

the working conditions so reasonable operation and maintenance of the screw conveyor to a more great Telescoping conveyors significance , screw conveyor operation and protection

Cultured main requirements are as follows:
1 screw conveyor should be no load starting , that no material in the shell when starting, after starting the beginning of the screw conveyor feeding .
2 screw conveyor irregularities occur during operation should be checked , and the elimination of , not forced to operate .
3 In order to ensure no load starting screw machine requirements , conveyor feeding should be stopped before stopping , and other material inside the chassis rear was completely

lost all stopped .
4 Screw the lid of Telescopic belt conveyor the machine is running should not be removed, so as to avoid accidents.
5 material being transported shall not be mixed with chunks of hard materials to avoid causing death card spiral screw machine damage.
6 Screw the initial feed , the feed rate should be increased gradually until it reaches the conveying capacity , feeding should be uniform, or likely to cause transport of

materials product plugs, drive overload , so that the whole machine early damage.
7 In use frequently viewed screw machine working status of each component , pay attention to the fasteners are loose , if you find loose parts , they should immediately tighten

the screws , so that re-tighten .
8 It should be coupled with special attention to the helical axis of the screw is loose, fall or cut, such as the discovery of such phenomena , it should be immediately stopped

, and correct it.
9 Screw the moving parts should be lubricated regularly .
( A ) within the application reducer drive gasoline engine lubricants HQ-10 (GB485-81) oil change once every 3-6 months .
( 2 ) spiral ends with lithium grease inside the bearing , once every half note , 5 g .
( 3 ) screw machine hanging bearing , the choice of M1 category , including 80000 type bearing assembly has infiltrated the oil , usually as little fuel ; every 3-5 months ,

together with the hanging hanging shaft bearing body removed , remove the seal circle, the hanging bearing and 80000 bearing immersed in molten lubrication with a grease

Road cooled , re-installed for use, such as nylon ring damage should be replaced with one year maintenance once again using the above method can obtain satisfactory results.
( 4 ) screw machine hanging bearing , use M2 category , class Note grease, greasing each hanging bush 5 g ; using self-lubricating bearing, should also be added to a small

amount of grease.
