How to deal with the side crack of vibrating screen?
Continuous vertical welding), each weld with a needle gun fight, until the completion of welding 5) grinding, polishing the weld. Until smooth surface and side plate surface.6) in a sieve. Lateral grinding the weld seam grinding as little as possible as long as the weld clean. And the parent material. Then the exposed side and the inner. The outside of the side plate welding.7) polishing,.8) will be at the top of the side hole grinding hole on the weld shaping, ensure all burrs have been removed, no grooves and dents.9) will finish coating area of the polished clean. Then the side plate and the reinforcing plate are coated on the painted primer. On both sides of the reinforcing plate. Placed in a sieve inside, and as much as possible to install bolts, reinforcing plate will weld repair area covered on both sides of.10) to tighten the bolts after drilling holes on the reinforcing plate, which is covered in the crack, hole into riveted bolts tight.
The first test of six angle bolt crack region is reliable. Remove the side plates on both sides of the angle steel and the upper reinforcing rivet bolt plate, with the damage surface between the check plate and angle. On the surface of qualified cases, ensure both ends aligned.2 side crack) along the crack center in the entire length of a grinding groove (sieve inside) 3) along the crack and the sieve plate is perpendicular to the direction of welding, the welding torch can not swing, can be divided into 2 segments and each weld in welding, after using a needle gun blow, eliminate stress and welding slag.
The repair area at the top of the side plate grinding, grinding angle and lateral primer. In the medial angle on with reinforcing plate on both sides of the weld in at least 3.12 riveting riveting bolts) when all rivet bolt riveting, in the repair area painted lacquer topcoat. After drying, with SIKA glue around the reinforcing plate sealed to prevent corrosion. The analysis of the application of high frequency vibration in quartz sand production process in the maintenance of sieve shaker common fault and maintenance method of how to choose the appropriate circular vibration sieve application specific process of vibration screening equipment in vibration screening in industry and agriculture.
