Bucket elevator installation requirements analysis

(1) bucket elevator lower section of the support surface, we must ensure is located in the base of the horizontal plane.
(2) the bucket elevator shaft and lower upper tensioning shaft shall be within the same vertical plane, and the two should be parallel to the horizontal axis line.
(3) intermediate housing flange connections, may not have a significant dislocation. Flanges can pad into asbestos pad or waterproof canvas to ensure the seal.
(4) bucket elevator machine lower section, the upper section of the intermediate housing and in the same vertical line centrelines, the vertical deviation of the length of the upper part of 1cm allowed to exceed 1mm, the cumulative total height deviation not exceeding 8mm .
(5) the traction member hopper should be positioned correctly and securely tightened. In operation, there should be no deflection and collision case phenomenon.
(6) Bucket Elevator deflection plates installed, must comply with the requirements of the drawings.
(7) After adjusting screw tension device should make the traction member having a uniform required for normal operation of the tensioning force. In order that there is sufficient tension in operation stroke to be less than the rest of the tensioning stroke of 50% of the full stroke
(8) the axis of the high speed shaft of the gear unit and the motor axis to be parallel to each other in the same horizontal plane; slow axis and the axis of the drive shaft axis of the bucket, to be on the same horizontal line, the maximum offset is not parallel more than 0.2mm, the maximum angle between the axis must not exceed 40o.
(9) bucket elevator lifting equipment should be installed, from the weight of not less than 2t. Crane rail base and shaft centerline distance is generally 22.2m. For D160, D250 bucket elevator to take 2m; For D350, D450, HL300 \ HL400 bucket elevator to take 2.2m.
