Basic requirements 1, hoist shall comply with the requirements of this standard and JC460.1 and design drawings and technical documents in accordance with procedures approved by the provisions of the manufacturing, installation and use of this standard, drawings and technical documents are not technical requirements bucket elevator, according to common standards concerning building materials machinery, mechanical and electrical industries, such as the implementation of .2, tolerance did not note the size limit on the pattern deviation should comply with the provisions of GB 1804, which was tTl3 machined surface level; welding pieces of non-machined surface ITl6 level; forging documents non-machined surface .3 ITl5 class manufacturing, welding shall comply with the relevant provisions of building materials machinery welding .4, gray iron castings shall comply with the provisions of .5 GB 9439, forgings shall have a sandwich, folding, crack, satin injury, knot scars, slag and other defects .6, hoist should be set level meter, monitor and tape speed anti-deviation device. Model selection as common lifting equipment, the choice of bucket elevator by the constraints of the wrong number of factors Models will bring untold trouble using the square. General decided bucket elevator selection depends on the following factors: 1, shape material: material is powdered or granular or small block. 2, the physical properties of materials: Material has no adsorption or viscosity, whether moisture. 3, the proportion of materials: general bucket elevator parameters are for bulk density in the material design and calculation of 1.6 below the bucket elevator supply much needed traction proportion of material tensile strength calculation and transmission parts. 4, delivery amount per unit time. In the bucket elevator machine head equipped with anti-reversing device. In the bucket elevator work force suddenly interrupted, reversed for bucket elevator is very dangerous. Bucket elevator in the promotion process, which is the upstream side of the basket full of doo hoist offer materials, and the other side is emptied of material downstream empty bucket. After a power interruption, bucket elevator reversal will occur due to gravity. With bucket reversal materials are discharged into the bottom of the bucket elevator machine until after bucket filled with jam. Reversal is due to an accelerated movement, and then was suddenly stuck bucket elevator prices, it is easy to tear off the bucket, so that the belt is damaged, or even broken. Also at the bottom of the bucket elevator filled with the material, but also the bucket elevator can not start. Anti-reverse ratchet mechanism can be used bucket elevator bucket elevator manufacturers _ _ Qingdao Xudong electrical equipment supplied by Power Equipment Co., Ltd. Qingdao Xudong.
