Maintenance method of stenter machine equipment:
1. Cylinder (Dg1100×6): welded by steel plate. There should be no long-term accumulation of water (steam cooling water) in the cylinder. The cooling water should be drained and dried after damp and heat setting, and the inner surface should be checked regularly for peeling, rubbing and falling off. If so, it should be repainted in time Rust paint to prevent local corrosion. Note: The maximum vacuum during use should not exceed 0.07MPa (actually generally above 0.06MPa) to prevent instability.
2. Jacket of setting machine: It is made by coil welding of steel plate. Used for dry heat setting. The main bearing is 45° fold on the head. During maintenance, 80-100 mm of asbestos cement insulation layer should be added to the outer surface of the jacket according to the drawings, and the cooling water in the jacket should be drained after each use.
3. 2 support pipes and 11 accessory pipes: check whether the pipe teeth are in good condition during maintenance, apply anti-corrosion lubricant such as molybdenum disulfide on the thread before installing the pipe, and install cushions at the flange connection to ensure various air pipes No leaks, no leaks.
4. The movable ring, fixed block, roller, rack, handle and other parts of the setting machine: pay attention to the thread or other dirt embedded in the roller and affect the rotation. If the roller is sluggish, loosen the compression screw appropriately.
5. Various pressure gauges, thermometers, safety valves, jackets, vacuum gauges, etc. of the setting machine: For these instruments, they must use the specified specifications and models to reach the specified measurement range and accuracy level; regularly check their sensitivity, accuracy, reliability.
