centrifuge sieve basket
production technology and technical requirements of sieve basket
We according to user requirements, choose different specifications and types of low carbon steel wire, stainless steel wire in special processing equipment, rolled the support rod and sieve rold into shape, and then according to user's requirements of different slot in the special equipment and supporting the admiral of welding, and then put into the sieve inspection of the screen mesh, making fan last in special molding admiral, fan nets, flanges, strengthen the ribs, strengthen compound shape. Ring, etc. The key is to control the screening process of welding distortion, so the screen basket in the special die parts molding compound, must ensure accurate positioning, clamping, after the completion of the compound, after stripping finalizes the design, mould. In the dynamic balance machine do dynamic balance test. After the final inspection, polishing, paint.
The stainless steel wire, coarse, after forming rolling rolling rolling for the wire section, after 20 percent reduction, density and hardness, wear resistance increased by 2 ~ 3 times. After finishing silk, back into the wedge section b, two round R (white) to less than 0.1 mm. Not suitable for waste, burr. When choosing reasonable welding welding parameters (welding current for 24-2600A contact pressure for 5-2 2 7MPa). 1 welding depth general 3mm ~ 1. Welding with "single solder tensile strength, average method for qualified 4500N experiment.it tensile force. Also available experience inspection: with forceps, do reciprocating motion of support, support the disconnect solder, each cylinder nets are required inspection, slot deviation ± 05mm 0. Screen basket all welding shall be welded, welding and welding, and leakage is not off, slag, weld edge, the welding quality defects such bite, to ensure the screen basket enough mechanical properties. Sift in fully-mechanized basket, should be smooth transition joining two adjacent the height difference than 1mm 0, screening and flanged end basket cone center of perpendicular tolerance weight than 1mm and flanged end of 0 0 unevenness acuities 5mm. Dynamic unbalance tolerance weight than 150 g · cm.
