The normal operating temperature range for Roots blowers is usually between 30 ° C and 90 ° C, but there may also be claims of 60 ° C to 90 ° C or 65 ° C to 90 ° C. This temperature range is based on the material and design considerations of the fan. Within this range, the fan can maintain stable operation and will not be damaged due to overheating. The following is a detailed analysis of the working temperature of Roots blower:
1. Environmental temperature: The higher the ambient temperature used, the higher the temperature of the fan will also increase accordingly. Therefore, in order to maintain the normal temperature range of the Roots blower, it is necessary to control its ambient temperature. In high-temperature environments, additional cooling measures may need to be taken, such as building fan rooms or using fans, air conditioning, and other equipment to lower the ambient temperature.
2. Inlet temperature: If the inlet temperature is too high, it will increase the operating load of the fan, leading to an increase in temperature. Generally speaking, the inlet temperature of a Roots blower should not exceed 40 ° C (some argue that it should not exceed 45 ° C). During high temperature seasons such as summer, special attention should be paid to controlling the intake temperature to avoid overheating of the fan.
3. Load situation: The larger the load on the fan, the more heat it generates, and the temperature will naturally rise. Therefore, in practical applications, it is necessary to adjust the operating parameters of the fan according to its load situation to maintain its operation within the normal temperature range.
4. Pressure and speed: The outlet temperature of the Roots blower is directly proportional to the pressure. For every 20 kPa increase in pressure, the temperature will increase by approximately 1.1 degrees Celsius; At the same time, the higher the speed, the higher the temperature. For every 200 revolutions per minute increase in speed, the temperature will increase by 0.9 degrees Celsius. Therefore, when adjusting the fan pressure and speed, it is necessary to consider their impact on temperature.
5. Body temperature calculation: The calculation method for the body temperature of a Roots blower is usually room temperature plus a 10 ° C increase in temperature for every 1000 millimeters of water column rise (within this range is normal, exceeding it indicates that the Roots blower temperature is too high). This formula can help users quickly determine whether the temperature of the fan body is normal.
6. Maintenance status: Regular maintenance and cleaning can ensure the operational efficiency of the fan and avoid unnecessary temperature rise. Users should regularly check the wear of the bearings, gears, impellers, and other components of the fan, and replace severely worn parts in a timely manner.
In summary, in order to ensure that the Roots blower operates within the normal temperature range, users need to comprehensively consider factors such as ambient temperature, intake temperature, load conditions, pressure and speed, and maintenance status. At the same time, the temperature of Roots blowers produced by different manufacturers may also vary, depending on the adjustment of the clearance between the various components of the blower and the quality of the main components such as bearings, gears, and impellers. Therefore, in practical applications, users need to judge and adjust the operating parameters of the fan according to specific situations.
