The working temperature range of Roots blower is usually between 0 ℃ and 60 ℃, and there are also claims that its normal working temperature range is 30 ℃ to 90 ℃. Specifically, the temperature resistance performance of Roots blowers is influenced by various factors, including the design, material, operating environment, and conditions of the blower.
Material and temperature resistance performance
1. Cast iron material: The commonly used Roots blowers on the market are mostly made of cast iron material, which exhibits good performance within the conventional temperature range, but may be limited in high-temperature environments.
2. Stainless steel material: For applications that require handling high-temperature gases, Roots blowers may use stainless steel material to improve their temperature resistance.
Usage environment and operating conditions
1. Inlet temperature: In summer, the inlet temperature of Roots blower should generally be controlled below 40 ℃ to avoid faults such as motor burnout caused by high temperature.
2. Outlet temperature and pressure: The outlet temperature of a Roots blower is directly proportional to the pressure, and the higher the pressure, the higher the temperature. Therefore, under high-pressure operating conditions, special attention should be paid to the temperature resistance performance of the fan.
3. Cooling measures: For Roots blowers that need to handle high-temperature gases, special cooling measures may need to be taken, such as using water-cooled Roots blowers, and paying attention to preventing the water-cooled pipes from freezing or cracking in winter.
precautions
1. Regular inspection: Whether in summer or winter, the temperature of the Roots blower should be checked regularly to ensure that it operates within its range.
2. Special customization: If the gas temperature to be transported is high or the operating environment is special, a Roots blower with higher temperature resistance may need to be customized.
