What is the working preparation for screw conveyor installation?

1.The screw conveyor foundation should be completed before installation for 20 days which will make the foundation secure and reliable,and will prevent screw conveyor from sinking and deformation to ensure screw conveyor with enough stability when running.
2.The casing installation should accord with following stipulation:
(1)Allowed longitudinal straightness error is 1/1000 of length,total length error is 3mm.
(2)Allowed horizontal straightness error is 1/5000 of width.
(3)The inner wall of the casing is equal to the two sides of the screw blade,and the error is allowed to be 2 mm,the bottom interval error is ±2 mm.
(4)The connection of casing should be closely,and no interval is allowed.
(5)The casing should be fully contacted with structure support.
3.Allowed overlap error of center line between shaft and bearing is 0.5mm.
4.There should be no apparent height difference between two adjacent casings.
5.Please adjust and steady casing before tightening foundation bolts.
6.Output shaft of driven device should be in the same axis line with screw conveyor shaft.
7.If the inlet and outlet need to be installed on site,please weld them after fixing the total machine.
