Reasons for the Powder Leakage in Intensive Mixing Machine and Solutions
It could be that there is an uneven contact area between the static and dynamic rings of the extruder, resulting in a lack of a sealing oil film.
Process: Disassemble and inspect the extruder's fixed ring. The drag contact area is not scratched, but the contact rate is low. In this case, a磨合 treatment is required, which should last for more than 4-8 hours. During the磨合, the contact area must not be interrupted by oil supply.
2. There may be hard particles between the dynamic and static rings of the extruder, scratching the contact area and causing the contact surface to lack a sealing oil film.
Method: If the moving coil is damaged, use an oil stone to grind and repair it, using the device for grinding. The fixed coil is a two-section structure, allowing for disassembly and grinding. After grinding the plan view of the moving and fixed coils, reassemble the fixed coil, then slowly grind for several hours, applying lubricant during grinding.
3. Possible delamination of the aluminum alloy anode ring in the compounding machine
Procedure: Replace the moving coil, then set it, and run the moving coil for several hours.
4. It may be due to a blockage in the extruder lubrication tube, resulting in the interruption of oil supply or insufficient oil being provided, which causes damage to the moving and stationary rings.
Approach: Clear the blocked pipeline and investigate the cause of the blockage.
5. Possible oil leakage at the three-way connector of the extruder.
Solution: Damaged sealing ring at the interface; replace with a mouth-shaped sealing ring.
6. Possible issues include a cracked oil tube in the extruder or a crossover between the sub-oil tubes, resulting in leakage through the alarm conduit.
Method: Repair damaged piping and alarm systems.
7. It is likely that the wear between the plunger and the plunger sleeve of the extruder lubrication pump is significant, leading to a decrease in the working oil pressure and insufficient remaining oil.
Solution: Replace the oil pump plunger and sleeve.
8. It is possible that the tightness of the clamping bolt on the密炼机's 定圈 spring is uneven or not properly seated.
Solution: For the old-style kneading machines, retighten the bolts. For the newly modified kneading machines, adjust the sealing to lever-type, use butterfly springs for the clamping springs, and ensure that the torque spring for the nut is properly implemented. Insufficient contact pressure on the sealing surface is due to inadequate implementation; it should be re-planned according to specifications.
