Product Overview
The WF-TW Horizontal Oil-Cooled Permanent Magnet Adjustable Speed Drive is a high-efficiency, energy-saving speed control device developed by Anhui voofu Permanent Magnet Technology Co., Ltd. for equipment such as horizontal vane pumps and fans above 630kW. The product adopts permanent magnet drive technology and achieves a soft connection between the motor and the load through non-contact torque transmission. It features a wide speed regulation range, significant energy-saving effects, and stable, reliable operation. It is widely used in energy-saving retrofits of fans, pumps, and other equipment in industries including power, metallurgy, chemical, cement, and coal.
Product Features
1. High Efficiency & Energy Saving:
Wide Speed Regulation Range: Supports 30%-97% stepless speed regulation, allowing precise adjustment of load speed according to actual demand, avoiding the "big horse pulling a small cart" phenomenon, with a power saving rate typically reaching 20%-50%.
Soft Start Function: The motor starts under no load, and the load accelerates smoothly by adjusting the air gap, reducing starting current surge and extending the life of both motor and load.
No Harmonic Interference: Pure mechanical speed regulation without power electronic components, avoiding harmonic pollution to the power grid and reducing reactive power loss.
2. Structural Advantages:
Oil-Cooled Heat Dissipation: Uses thin oil as the cooling medium, dissipating heat through oil circulation, effectively controlling disc temperature while lubricating bearings, reducing wear, and extending bearing service life.
Compact Design: The equipment has a compact structure, small footprint, and low pipeline loss, facilitating on-site layout and maintenance.
High Reliability: Non-contact transmission design isolates vibration, reduces mechanical wear, and extends equipment service life.
3. Strong Environmental Adaptability:
Withstands Harsh Environments: Operates stably in extreme temperatures from -40°C to +100°C, suitable for high-dust, humid, flammable and explosive locations.
Explosion-Proof Performance: The main power part transmits torque without friction, generating no sparks or static electricity, suitable for applications with high explosion-proof requirements such as coal mines, oil fields, and chemical plants.
4. Low Maintenance Cost:
Maintenance-Free Design: No bearings or wear parts, requiring only periodic air gap and lubricating oil inspection, with a design life of up to 30 years.
Low Failure Rate: Non-contact transmission isolates vibration, reduces mechanical stress, and lowers the failure rate of various transmission system components (such as bearings, seals, etc.).
Application Fields
The WF-TW Horizontal Oil-Cooled Permanent Magnet Adjustable Speed Drive is widely used in the following scenarios:
1. Power Industry: Boiler induced draft fans, primary air fans, circulating water pumps, etc.
2. Metallurgical Industry: Blast furnace blowers, dust removal fans, cooling water pumps, etc.
3. Chemical Industry: Compressors, mixers, circulating pumps, etc.
4. Cement Industry: Kiln head and kiln tail fans, raw mill fans, circulating water pumps, etc.
5. Other Industries: Fans, pumps, and other equipment in municipal water supply, wastewater treatment, papermaking, textiles, and other industries.
