Several methods to reduce the temperature of the Roots blower
Release time:
2021-05-24
The Roots blower has good sealing performance, high efficiency, low noise, and small vibration. The working principle of this method is: the two non-contact rotors of the Roots blower move in opposite directions at the same speed within the cylinder, pushing the airflow from one side to the other. When the high-speed airflow reaches near the exhaust port and connects with the exhaust port, the pressure in the working space suddenly increases because the high-pressure gas flows back, and the gas is discharged. The Roots blower relies on the synchronous gears on the rotor shaft ends to maintain the engagement of the two rotors. The concave part of the rotor forms a working space with the inner wall of the cylinder. As the rotors rotate, gas is discharged from the intake port, and the two rotors operate alternately. Increasing power, strengthening the rotor group, enlarging the volume, increasing speed, and adjusting the impeller clearance enhance the compression of air in the chamber and increase the pressure.

ReduceRoots blowerThere are many methods to lower the temperature. Today I will introduce some commonly used methods:
First, some places have sound insulation requirements and are equipped with soundproof covers, and the box door needs to be opened in summer. The casing forms an airtight space, increasing the ambient temperature, resulting in a higher intake temperature and poorer outlet temperature. Many fans of Roots use the hood. The intake temperature exceeds 45 degrees in summer.
Second, the Roots blower is installed indoors; try to install an air conditioner as much as possible. Don't worry about the air conditioning and electricity. For every 10 degrees increase in motor temperature, its lifespan will be greatly shortened. Therefore, indoor air conditioning can extend the equipment's lifespan and reduce the outlet temperature.
According to the empirical formula, the outlet temperature of three fans = inlet temperature (10-12) * pressure.
This refers to the pressure of the water column in the instrument. For instance, if the water level is measured at 6 meters, the pressure loss in the pipeline and diaphragm loss (the sewage treatment plant has gas pipe diaphragms) is 1μm. Additionally, if the ambient temperature is below 30 degrees Celsius, the outlet temperature can range from 100 to 114 degrees Celsius.
Using this formula, we can understand the meaning of inlet temperature and outlet pressure.
Reduce pipeline curvature and other factors to minimize pipeline pressure losses as much as possible.
There is also a simple method, from about 5-10 meters long outlet pipe to install a receiver (especially suitable for breeding ventilation, sewage treatment, etc.), which can effectively reduce the outlet temperature.
