Operating Procedure
1. Preparation
Check steam pressure (5-10 kg/cm²G), water pressure (1-2 kg/cm²G), and power supply, ensuring the filter is not blocked.
Set the nozzle gap, ensuring consistency on both sides to avoid uneven fabric speed.
2. Dyeing Operation
After loading the fabric, inject the dye solution through the dosing tank, controlling the liquor ratio at 1:6-1:10.
Start the circulation pump and heating device; high-temperature and high-pressure models require a sealed cylinder (temperature can reach 140℃).
Monitor the fabric speed (500-600 m/min) and dyeing uniformity, using the air-water separation device to prevent fabric entanglement.
3. Post-treatment
After dyeing is complete, activate the overflow washing function to remove residual liquid and thoroughly clean the dyeing tank.
Maintenance Points
1. Daily Maintenance
Regularly lubricate transmission components (such as reducers and bearings) and check the integrity of the seals.
Clean the heat exchanger inlet filter to prevent blockage and maintain circulation efficiency.
2. Safety Maintenance
High-temperature and high-pressure models require regular calibration of the safety valve and pressure testing.
Wear protective equipment during operation to avoid direct contact with high-temperature components or dyes.
3. Energy Saving Optimization
Use a tank-type main cylinder structure to reduce the liquor ratio and optimize the dye liquor circulation system to reduce energy consumption.
Precautions
Different fabrics require adjustment of the air-water separation speed (by-pass) and fabric speed to avoid damage.
High-temperature models require the use of corrosion-resistant materials (such as stainless steel) to prevent cracking in chloride environments.
