There are many factors influencing the outlet temperature of a blower, including volumetric efficiency, working pressure, internal leakage, and the temperature of the intake air. Here are some methods to reduce the temperature of blowers, particularly in pneumatic conveying systems:  

1. Open the soundproof enclosure doors: Most blowers are equipped with soundproofing devices. During summer, it is essential to open the doors of the soundproof enclosure. The soundproof enclosure creates a sealed space, increasing the ambient temperature, which leads to higher intake air temperatures and significantly higher outlet temperatures. For many blowers equipped with soundproof enclosures, the intake temperature during summer can exceed 45°C.  

2. Install air conditioning for indoor blowers: If the blower is installed indoors, consider installing air conditioning if possible. Do not hesitate to invest in air conditioning and electricity costs, as the lifespan of the motor decreases significantly for every 10°C increase in temperature. Installing air conditioning indoors can extend the equipment's lifespan and reduce the outlet temperature.  

3. Reduce inlet temperature and outlet pressure: Lowering the inlet temperature and outlet pressure can help reduce the blower's temperature. To understand why, you need to refer to the formula:  

  Blower outlet temperature = Inlet temperature + (10-12) × Pressure.

4. Minimize pipeline bends and pressure losses: Reduce bends and other pressure losses in the pipeline as much as possible to lower the overall pressure loss in the system.
