The filter and spinning system manufacturer tells you that in the process of replacing the split meltblown spinning assembly, various components in the assembly, such as filters, spinnerets, air knives, etc., are installed on the spinning box one by one. Continue to test the fit relationship between the parts during the installation process, and conduct a comprehensive inspection and adjustment again after the initial assembly (mainly the airway clearance and both sides of the cone), after reaching the working temperature (or running after a period of time) Even hotter fastening and fine-tuning again until specifications are met.
After the spinning components are installed on the spin box, the components need to be heated using the ventilation air flow and the heat of the box, which requires a long heating and equilibration time before it can be put into operation. Filtering and spinning system manufacturers tell you that if there is insufficient equilibration time, the spinneret will start and run before the tip of the spinneret reaches operating temperature. Due to the high flow resistance of the melt, high pressures tend to develop in the part and box, which can lead to cracks and damage to the spinneret (the same potential hazard exists for integral parts).
The components of the melt blown spinning unit are precise and complex mechanical workpieces and must therefore be installed with great care. Filtering and spinning system manufacturers tell you that although the installation of split components will take more time, the smaller size and weight of this form of spinning components can generally be done with small special tools or manually. In addition, because the matching relationship between parts is not fixed, it can also be optimized and adjusted according to the production process requirements or product quality (mainly the width of the air passages on both sides), which has certain flexibility.
