I. Basic Maintenance Cycle Routine Maintenance: Perform flushing and sealing operations every 4 to 6 weeks to prevent tubing blockage and infection. Long-Term Storage: If not used for more than one mo

I. Power Supply and Circuit Malfunctions Symptom: Indicator light does not respond after startup. Cause: Damaged wiring or circuit board; interrupted connection between gear shaft and piston push shaf

Key operational points: 1. Main pump flow control: Set the main pump flow rate within 80%-100% of its rated range using a frequency converter. This is fundamental to stabilizing nozzle pressure. 2. No

Equipment Parameter Settings 1. Liquid Level Control: Use a differential pressure transmitter to precisely control the liquid level, ensuring a constant influent flow rate through a table that correla

1. Basis for liquor ratio setting Fabric type: Lightweight fabrics require a higher liquor ratio (e.g., 1:18), while heavyweight fabrics can be reduced to 1:10. Equipment characteristics: Hardware suc

1. Equipment Parameters Nozzle Gap: Needs to be adjusted according to the fabric weight; the larger the weight, the larger the gap to ensure uniform dye penetration. Liquor Ratio Control: The ratio of

1. Fabric characteristics The fabric weight directly affects the selection of the nozzle gap; the higher the weight, the larger the gap needs to be. Fabric twist also affects the uniformity of dyeing.

Operating Steps: 1. Determine Fabric Weight: Different fabric weights require different nozzle gaps. Generally, the higher the weight, the larger the gap is needed to ensure sufficient dye penetration

1. Inspect the Circumferential Cracks at the Rear (R) Area of ​​the Dye Head This is a common malfunction in J-type dyeing machines and requires regular macroscopic inspection. Pay close attention to

1. Pre-operation inspection: Often overlooking to check the R-section of the machine head (prone to circumferential cracks), the chloride ion concentration of the dye liquor (which easily corrodes equ

Pre-operation inspection is fundamental. Ensure the equipment is stopped and the power is disconnected. Remove any foreign objects from the interior. Check that the power supply, steam, water pressure

1. Inspection of Circumferential Cracks at the R-Site of the Dye Head This is a common fault in J-type dyeing machines, often caused by prolonged operation in high-temperature, high-pressure environme
