Precise measurement of specific low temperatures at -20℃, -30℃, -35℃, -40℃, -45℃, -50℃, -55℃ to check whether the lubrication pump can operate normally under the lowest temperature conditions.
WEIDUN's R&D Team uses WDS-I Electric Lubrication System to do a low temperature test of pumped lubricating grease. By analyzing the experimental data, the optimal pumping temperature range of the tested grease in the lubrication pump system was determined, providing a basis for temperature control in practical applications. Identify the lowest possible temperature at which grease cannot be pumped in an electric lubrication pump system, and define the product's usage boundaries in low-temperature environments. Define the minimum ambient temperature at which the electric lubrication pump can maintain stable operation in low-temperature environments; define the critical low-temperature range in which the pump body will malfunction due to low temperatures (such as motor overload, pump valve jamming, programmable controller failure) or be unable to achieve effective pumping.
By controlling the ambient temperature to a specific low temperature, the target lubrication pump and grease are brought to a corresponding temperature state. The electric lubrication pump is then started, and the weight of grease pumped per unit time is measured using a weighing device. Based on the pumping weight data at different temperatures, the influence of temperature on the pumpability of grease is analyzed, thereby determining the optimal pumping temperature range, the extreme low temperature at which grease cannot be pumped, and the minimum temperature and critical failure temperature range for stable operation of the electric lubrication pump.
By analyzing the test data, we found,
● -20℃~-40℃: Pumping rate remains relatively stable compared to room temperature.
● -45℃~-50℃: Pumping rate decreases rapidly compared to -40℃.
● -55℃~-60℃: Pumping rate decreases significantly compared to room temperature; at -60℃, there is no pumping capacity because the grease cannot flow, and the pump body cannot function.
Conclusion
Lubricating grease: The optimal pumping temperature is no lower than -40℃; the extreme low temperature at which the grease cannot be pumped due to loss of fluidity is -60℃.
Electric lubrication pump: The lubrication pump can operate without failure in an environment of -60℃. The performance of the grease has a significant impact on the stability of the lubrication pump's operation.
The test shows that WDS-I Electric Lubrication System can operate in extremely cold environments, like some regions of Russia, Canada, USA, Greenland, Iceland, Finland, Sweden, Kazakhstan, Mongolia...
