Prevention and Mitigation of Pollen Dispersal and High Temperatures in Spring
Our mining machines face two significant challenges with the advent of spring:
- High levels of pollen dispersal.
- Fluctuating temperatures and the onset of warm weather.
Our technical support team has compiled the following preventive and corrective measures for your reference.
Risks and Prevention of Pollen Dispersal
The dispersal of pollen such as cottonwood and willow typically varies based on the region, often peaking in March and April. The cottonwood and willow pollen are usually followed by other species, including small-leaf poplar and Canadian poplar. In most regions, a substantial portion (about 80%) of the willow pollen matures by mid to late April, resulting in a peak season lasting approximately one week.
Risk of Pollen: The fluff from these trees scatters in the air and can get sucked into the mining machine due to the large airflow required for heat dissipation by the fans. As the radiator structure within the miner is tooth-shaped, the pollen cannot be ejected and ends up blocking the radiator. This obstruction hampers effective heat dissipation, leading to frequent high-temperature protection triggers and potentially damaging the miner.
Prevention: Enhance your dust control measures by using fine mesh nets to minimize the impact on airflow. Regularly clean the nets once they collect a significant amount of pollen to avoid inhibiting airflow. Inspect your mining machines regularly, checking the interior using the inlet fan. If you notice an accumulation of pollen, disassemble the machine for cleaning. If the obstruction is not severe, removing the front fan and cleaning it with a brush or using an air pump for reverse blowing may suffice. For serious blockages, disassemble the miner for thorough cleaning, ensuring the boards are not mixed up.
Note: Always ensure the miner is powered off before performing these operations.
Risks and Prevention of Variable Weather
This condition is prevalent in colder northern regions. Those operating mining machines in these regions during winter should take extra caution.
Risk: In winter, northern temperatures range between -10°C and -20°C. As spring begins, temperatures gradually rise to 10°C-20°C. During winter, miners typically implement temperature control measures like reducing air intake, changing the mining machine’s orientation, and adjusting the machine’s location. Failing to readjust these measures promptly with the rise in spring temperatures can trigger the miner’s high-temperature protection.
Prevention: Timely adjustments in line with temperature changes are crucial. During the transition from winter to spring, large temperature fluctuations and differences are common, necessitating several phased adjustments. Start by adjusting the upper layer. Stay updated with weather changes, ensuring the intake air temperature doesn’t drop below 5°C during low nighttime temperatures, and the upper layer of the mining machine doesn’t exceed 35°C during high noon temperatures.
NOTE: The miner’s high-temperature protection is a safety feature and should not be triggered frequently. Repeated activations of high-temperature protection pose a risk of damaging the computing board.
