How to extend the service life of barrel screw? The wear and tear caused by the working of the barrel screw in high temperature and high pressure environment is inevitable, so the wear resistance of the barrel screw should be increased, and ways to minimize the wear of the barrel screw can be increased. Service life. 1. Control the processing temperature of the barrel screw Granular p
Maintenance method of barrel screw Maintenance methods of barrel screw are mainly the following eight kinds: 1. Avoid screw idling, slipping and other phenomena; 2. Avoid mixing POM and PVC into the barrel at the same time, the reaction will occur at the melting temperature and cause serious industrial accidents; 3. To prevent foreign objects from falling into the barrel and dam
How to reduce wear and improve the use technology of barrel screw The extruding screw works for a long time under high temperature, high pressure, high mechanical torque and high friction environment. The first few factors are required by the process conditions, and the loss caused by friction is inevitable. Generally, the screw has undergone surface nitriding treatment to improve the surfac
Tips for daily maintenance of bimetal barrel screw Bimetallic barrel screw daily maintenance tips: 1. Never start the machine when the barrel screw has not reached the preset temperature. 2. Prevent metal fragments and debris from falling into the hopper. If processing recycled materials, it is necessary to add a magnetic hopper to prevent iron chips from entering the barrel. 3
Why does the extruder barrel screw produce noise? In the process of extrusion processing, the screw of the extruder will make a noise when it rubs against the inner wall of the barrel.The reasons for this friction phenomenon are: 1. The assembly gap between the barrel screw of the rubber extruder and the supporting transmission shaft is too large, and the center lines of the two shafts
Introduction of bimetallic screw production process The bimetallic screw and barrel bimetallic process is a more commonly used process combination product with excellent corrosion resistance and wear resistance in recent years. The HVOF high-speed spraying equipment is used to melt spray spray the surface of the screw to obtain a densely structured bimetallic Screw; the bimetallic barrel adopts
Routine maintenance of screw barrel of extruder Daily maintenance of screw barrel of extruder: 1. Never start the machine when the barrel screw has not reached the preset temperature. 2. Prevent metal fragments and debris from falling into the hopper. If processing recycled materials, a magnetic hopper should be added to prevent iron scraps from entering the barrel. 3. Make sure
What is the effect of excessive clearance between screw and barrel? Influence of excessive gap between screw and barrel: 1. The gap between the screw and the barrel is too large, and the flow rate of the molten material during extrusion is unstable, and the product surface is prone to horizontal wrinkles. 2. The gap is too large, the extrusion melt pressure is unstable, so that the c
