What is the impact of a Roots blower blowing hot air?
Release time:
2021-07-02
Under certain working conditions, we need to deliver gas at room temperature, but the air delivered from the outlet of the Roots blower is hot air. What is the reason? Usually, the hot air at the outlet of the Roots blower is mainly composed of forced delivery, temperature, and other factors. Here is a detailed understanding:
Under certain working conditions, we need to transport gas at normal temperature, butRoots blowerThe air delivered from the outlet is hot air. What is the reason? UsuallyRoots blowerThe hot air from the outlet is mainly composed of forced delivery, temperature, and other factors. Here is a detailed understanding:
First is forced delivery.
When the Roots blower is transporting gas, it must perform forced compression on the fan. When selecting a fan, there is a main working pressure parameter, such as 39Kpa.Roots blowerDuring air compression, the maximum working pressure that can be tolerated is 39Kpa. When the pipeline working pressure exceeds 39Kpa, during the operation of the fan, the impeller contributes to the gas in the fan, converting the kinetic energy of the impeller into thermal energy of the gas, raising the gas temperature. Forced air compression operations will definitely lead to heating. Therefore, the exhaust gas from the Roots blower has a temperature.
Second is temperature.
During gas transmission, the temperature is generally controlled below 40 degrees Celsius. Exceeding 40 degrees Celsius requires higher characteristics for general fans in various fields, making it impossible to maintain good actual transportation effects.
Third is the harm of high temperature to the fan.
High temperatures can harm the fan's oil tank, hydraulic seals, rolling bearings, etc., and in severe cases, can lead to fan failure and stop working. In the daily inspection responsibilities, the temperature of the fan casing, rolling bearings, and oil tank must be checked, and daily records should be kept.
Roots blowerThe hot air at the outlet is mainly affected by forced delivery, the operating temperature of the body, temperature, and other factors. Appropriate heat dissipation measures should be noted. High-temperature air affects the body and accelerates equipment wear, shortening the service life of the Roots blower, so measures should be taken.
