NMRV Worm Gear Reducer
I. Product Overview
Modular design with an aluminum alloy die-cast body, compact, lightweight, fast heat dissipation, smooth start-up, wide transmission ratio range, surface treated to prevent rust, stable performance, attractive and durable, and reliable quality.
II. Structural Features:
1. Aluminum alloy casting housing, suitable for full-angled installation configurations.
2. Adequate cooling ribs, ensuring the body has excellent thermal conductivity.
3. 10 types of base specifications from 025 to 150. Power transmission range from 60W to 15KW.
4. Wide speed ratio range, each individual machine base offers 12 reduction ratios ranging from 5:1 to 100:1.
5. High-efficiency, hard gear surface precision ground worm gears with large output torque.
6. Low noise and stable operation, capable of long-term continuous work in harsh environments.
7. Lightweight with high mechanical strength. Can be combined with a DC motor to form a worm gear reducer motor.
Section 3: Performance Features
1. Due to the lower operating current of high-voltage, high-power motors compared to the standard 380V motors, the size of high-voltage motors is significantly reduced; this saves installation space and lowers equipment costs.
2. Due to the motor's power being close to that of the high-voltage generator, it reduces the energy reserve power of the diesel generator, thereby lowering the cost of fuel and lubricant consumption for the diesel engine.
3. Electric motor control systems are simpler and more convenient than liquid oil motor systems, with faster control speed, higher efficiency, longer runtime, and simpler maintenance and management.
4. High-voltage motors drive underwater mud pumps or cutter heads directly through couplings, eliminating the need for previous long shafts, bearing bases, gearboxes, and auxiliary equipment. This reduces energy loss in the motor's drive load process and improves transmission efficiency.
5. High-voltage motors feature reasonable structure, easy installation, and reliable performance, making them an ideal drive equipment for long-term underwater operation.
Section 4: Usage Precautions
1. Prior to motor start-up: Check if the motor's high-level oil tank has the correct oil level; immerse the motor in water as much as possible to enhance its cooling efficiency.
2. In cold conditions: Start the motor's internal hydraulic oil circulation pump one hour ahead, monitor the vacuum gauge; turn on the pre-heater to heat the motor hydraulic oil to increase the operating temperature at motor startup.
3. To prevent motor overheating during startup, frequent starting is prohibited. The interval between each startup should be 20 minutes or more.
4. After the motor stabilizes: Regularly monitor the operating parameters on the gauge to ensure they are within the normal range; observe for any abnormal vibrations or noises in the motor; check if the oil level in the high-level oil tank is normal and if there are any oil splashes floating to the surface near the submerged motor; prevent oil leakage from the motor shaft seal and pipeline joints.
