Product Introduction

This is a special Variable Frequency Drive (VFD) system designed for AC motors matched with Water-jet looms and Air-jet looms. It is fully compatible with Junhe A2/A3/A4/A6 electronic control systems and direct drive motor solutions. The system achieves precise speed regulation, smooth start/stop, energy savings, and stable operation. Adopting a motor-specific computer control circuit + VFD technology, it efficiently matches AC motors, solving the pain points of traditional transmissions such as high energy consumption, poor speed regulation, heavy wear, and strong start/stop impact. It significantly improves weaving efficiency and fabric quality while reducing comprehensive operation and maintenance costs.

Application

1. Main drive speed regulation for Water-jet looms and Air-jet looms, achieving stepless speed adjustment suitable for various high-speed loom conditions.
2. Flexible manufacturing scenarios with multiple varieties and small batches, supporting rapid switching of loom speed and processes, suitable for high value-added fabric production.
3. Energy-saving upgrades for textile mill looms, replacing traditional transmissions to reduce equipment energy consumption and maintenance costs.
4. Complete line electronic control integration for textile mills, seamlessly integrating with Junhe weft feeders, electronic control systems, and direct drive motors.
5. Weaving scenarios requiring precise speed and start/stop control, such as high-density fabrics, elastic fabrics, and fine denier nylon fabrics.

Main Functions

1. Precise Speed Regulation: VFD control enables continuously adjustable loom speed to meet different yarn and fabric process requirements.
2. Smooth Start/Stop: Soft start and soft stop design eliminates mechanical shock and reduces wear on equipment components.
3. Multiple Protections: Features overload, overcurrent, and overvoltage protection to extend the lifespan of the motor and equipment.
4. Electronic Control Integration: Coordinates with the loom's electronic control system, supporting multi-speed control and swing frequency functions specific to textile machinery.
5. High Efficiency & Energy Saving: Saves 15%-20% energy compared to traditional transmissions, effectively reducing power costs.
6. Low Noise Operation: Low operating noise, suitable for long-term continuous high-load production in workshops.
7. Diverse Control Modes: Supports external terminals, control panels, communication, and other control methods, interfacing with mainstream loom systems.
8. Quick Style Change: One-key storage/recall of process parameters reduces debugging time and improves production efficiency.

FAQ

Q1: What are the advantages of Junhe‘s special model for textile machines compared with ordinary VFDs?

A: Junhe’s VFD system is specifically developed for loom working conditions, optimizing low-speed torque, start/stop characteristics, and anti-interference ability, adapting to high-humidity and dusty environments. It is deeply matched with Junhe electronic control, weft feeders, and direct drive motors, resulting in lower failure rates, stronger stability, more accurate energy saving, and faster ROI for the overall solution.

Q2: How much electricity and maintenance costs can be saved when matched with an AC motor?

A: VFD saves 15%-20% energy compared to direct drive. Soft start/stop greatly reduces mechanical wear, lowering annual maintenance costs by more than 40%. The advantage is even more significant in areas with high electricity costs.

Q3: Are there cooperation cases with textile mills of the same type as our company (e.g., high-end fabrics/large production capacity)? Can you provide customer contact information or on-site inspection opportunities?

A: We have long-term cooperation with many large textile mills engaged in the production of high-end fabrics (fine denier nylon/high elastic yarn) and large production capacity both domestically and abroad, covering Jiangsu, Zhejiang, Indonesia, Turkey, and other regions. With customer consent, we can provide detailed cooperation cases (production data, efficiency improvement data) and arrange on-site inspections. Customer contact information can be provided after signing a confidentiality agreement.

Q4: Can it interface with our existing looms and electronic control systems?

A: It supports mainstream Water-jet and Air-jet looms such as Toyota, Tsudakoma, Rijia, Haijia, Zhejiang Sanyou, Rifeng, Yinchun, Tianyi Hongqi, etc. Interfaces and communication protocols can be customized for rapid compatibility with your existing production lines.

Q5: What is the MTBF and service life?

A: The Mean Time Between Failures (MTBF) is ≥10,000 hours, and the design service life is 8-10 years under normal maintenance, which is higher than the general industry level.

Q6: Is on-site installation and debugging provided, and how long is the training?

A: On-site debugging by engineers is provided for bulk orders. Operation + basic maintenance training takes 1-2 days, with Chinese/English manuals and video tutorials provided simultaneously.

Q7: What about the after-sales response and maintenance cycle?
A: 24-hour response and 48-hour on-site service in China. Standby units are provided for core faults, with maintenance/replacement ≤72 hours. Overseas maintenance stations support remote diagnosis and fast spare parts logistics.

Q8: How long is the warranty, and is extended warranty supported?

A: 12-month warranty for the whole unit, free maintenance/replacement for non-artificial faults during the warranty period. Paid extension to 24/36 months is available, including priority service and spare parts discounts.

Q9: What is the delivery cycle and payment method?

A: 15-20 days delivery for regular orders. Payment: 30% prepayment + 70% settlement before shipment. Sample testing is supported, and the sample fee can be deducted from the bulk order payment.

Q10: Is the supply of wearing parts stable, and what about the pricing?

A: Core components and wearing parts are stocked year-round. The domestic procurement cycle is ≤3 days, priced at only 60%-70% of imported competitors. Long-term supply agreements can be signed.
