Roots blower has the feature of forced air supply and hard exhaust, that is, when the pressure changes, the flow changes little. In other words, the pressure can be "automatically" adjusted within the allowable range, while the flow changes little.
The pressure changes with the change of system resistance and is adaptive. Roots blower has no internal compression, so how much pressure the system needs, and how much pressure can be provided by Roots blower when the motor power is allowed. Therefore, the pressure is adaptive.
Roots blower is compact in structure, small in size and light in weight. The transmission medium does not contain oil. There are narrow gaps between roots blower rotors and between rotors and machine washes and wallboards, so there is no connection between rotors during high-speed operation, so there is no need to add oil to rotors, and the medium is oil-free. Roots blower has good sealing performance, high precision of main parts, advanced and reasonable structure, regular selection, stability, small vibration and low noise.
Causes of hot air blowing from roots blower:
1. Forced delivery of gas
When Roots blower is conveying gas, it needs to carry out forced compression on the fan. When selecting the fan, there is a pressure parameter, such as 39Kpa. When Roots blower compresses air, the maximum pressure it can withstand is 39Kpa. When the pressure of the front pipe reaches 39Kpa, the fan can overcome the pressure and operate normally. Forced compressed air operation will inevitably generate heat, so the exhaust fan of Roots blower comes out with a certain temperature.
2. Inlet temperature
When delivering clean air, the inlet temperature is generally controlled below 40 ° C and above 40 ° C. It is difficult to achieve good delivery results because of high performance requirements for ordinary fans in all aspects.
3. Inlet temperature of normal fan
If we deliver clean air, the outlet temperature should be kept below 100 ℃ as far as possible. If the temperature exceeds 100 ℃, we need to water cool the oil tank. If we use a fan with high pressure, we need to use a two-stage series fan and install a cooler to cool the air.
4. Influence of high temperature on fan
The high temperature will have an impact on the oil tank, seals, bearings, etc. of the fan, which may seriously cause the fan to fail to work. In the work content of daily inspection, the fan body temperature, bearing temperature, oil tank temperature, all need to be checked and recorded every day.
I believe that after reading the above, you should also understand the reason why Roots blower blows hot air. I hope it will help you.
