Which is more effective in cooling the oil pool of R series reducers with water cooling or oil cooling system

Comparison of Core Cooling Effects

Water cooling system: The specific heat capacity of water is about 4.2 kJ/(kg ·℃), and the thermal conductivity is about 0.6 W/m · K, which is much higher than the 2.1 kJ/(kg ·℃) of oil. The heat transfer efficiency can reach 1.5 to 2 times that of oil cooling.

Conventional oil cooling system: with air-cooled oil cooler as the core, the final heat dissipation is limited by the ambient air temperature, and the heat dissipation capacity will significantly decrease in high temperature environments.

Actual test performance: Under continuous full load conditions of high-power R series reducers above 30kW, water cooling can stably control the oil pool oil temperature within 65 ℃, which is 10-15 ℃ lower than the final oil temperature of the same specification oil cooling system.

2、 Differences in adaptability to different working conditions

Priority should be given to water-cooled scenarios: R-series reducers with long-term ambient temperature>40 ℃, 24-hour continuous full load operation, and power ≥ 30kW, such as plastic extruders and mining conveyor line supporting models.

Priority should be given to scenarios with oil cooling: small and medium power (≤ 30kW), no stable industrial water source, low temperature environment, or working conditions with extremely high requirements for leak prevention, such as ordinary conveyor lines and packaging equipment supporting models.

3、 Comparison of operational and maintenance risks

Water cooling system: There is a risk of cooling water leakage mixed with lubricating oil, causing oil emulsification. Anti freezing treatment is required in low-temperature environments, and pipe Louis scaling and blockage may occur in poor water quality.

Oil cooling system: No risk of oil-water mixing, good low-temperature adaptability, no need for additional water sources, daily maintenance only requires regular replacement of filter elements.
