Does the oil temperature of the loom reducer exceed 80 ℃? Comparison of Experimental Results of Four Low Cost Cooling Solutions

When the oil temperature of the loom reducer exceeds 80 ℃, four low-cost cooling schemes have been tested to reduce the temperature within the range of 8-25 ℃. Among them, the lubrication optimization scheme has the highest comprehensive cost-effectiveness, and the forced air cooling cooling effect is the most significant. It can quickly control the oil temperature within the safe threshold and adapt to the 24-hour continuous operation requirements of the textile workshop.

1、 Comparison of Experimental Results of Four Low Cost Cooling Solutions:

2、 Details of actual testing and operational points for each plan

1. Optimization of lubrication system

Test operation: Replace the original ordinary gear oil with N220/N320 heavy-duty extreme pressure gear oil, adjust the oil level to 1/2~2/3 of the oil level gauge, and clean the flying flowers and metal debris in the oil circuit

Actual test effect: Reduce tooth surface friction heat from the root, stabilize oil temperature drop by 8-12 ℃, and extend oil change cycle by 30%

Avoiding pitfalls: Do not mix different grades of lubricating oil to avoid a decrease in oil film strength and secondary heating

2. Cleaning of the cooling surface of the body

Actual operation: After shutdown, use kerosene to clean the accumulated cotton wool and oil stains on the heat dissipation ribs of the box, fully exposing the heat dissipation surface area

Actual test results: Heat dissipation efficiency restored to over 30%, oil temperature naturally decreased by 5-10 ℃, zero additional energy consumption

Adaptation feature: Completely zero renovation cost, it is a necessary basic cooling step for daily maintenance in textile workshops

3. External forced air cooling

Test operation: Install a 120W axial flow fan on the non transmission side of the reducer, align it with the cooling ribs of the box, and continuously supply air. It can be paired with a simple temperature control switch to achieve automatic start stop control

Actual test effect: The cooling range can reach 18-25 ℃, and the long-term oil temperature above 90 ℃ can be stably controlled within 65 ℃

Maintenance points: Clean the flying flowers on the dust cover of the fan every month to prevent air duct blockage from affecting the heat dissipation effect

4. Environmental ventilation renovation

Actual operation: Remove the obstruction within 20cm around the reducer, install a post exhaust fan in the corresponding area of the workshop, and form a directional airflow to take away the accumulated heat in the environment

Actual test effect: The overall ambient temperature has decreased by 5-8 ℃, and the oil temperature of a single gearbox has synchronously decreased by 10-18 ℃

Adaptation advantage: It can cover multiple adjacent weaving machines at the same time, and the cost of single machine transformation is lower after sharing

3、 Suggestions for scheme selection

Temporary emergency cooling: Priority should be given to cleaning the body's heat dissipation surface and external forced air cooling combination, which can reduce the oil temperature from 85 ℃ to a safe range of 70 ℃ within 1 hour

Long term low-cost operation and maintenance: With regular optimization of the lubrication system as the core, cleaning the heat dissipation surface every 3 months can avoid over 90% of the repeated problems of oil temperature exceeding 80 ℃
