With the temperature gradually rising in summer, the temperature at the inlet of Roots blower is high. In addition, the temperature rise caused by the pressure rise during the operation of the blower makes the surface temperature of the fuselage higher than other times. The specific normal temperature of the three blade roots blower during operation is determined by the inlet ambient temperature+working pressure value.
When three blade roots blower is used in summer and winter, the inspection density of the blower should be increased from 1 to 2 times a day to 3 to 4 times. In case of failure, the blower should be shut down for inspection. For water-cooled Roots blower, attention shall be paid in winter to prevent the water-cooling pipe from freezing or cracking, and the water inside the water-cooling pipe shall be cleaned when it is shut down.
In summer, the inlet air temperature of Roots blower is generally controlled below 40 ℃. If the temperature exceeds this temperature, the Roots blower may be overheated and the motor is easy to burn. The low temperature in some areas may also be related to altitude. If the altitude is high and the temperature is low, special attention should be paid to the selection of Roots blower. The selection cannot be carried out according to normal conditions. Altitude has an impact on air volume and pressure.
The general types of Roots blower are mainly placed above the ground, and the ambient temperature will affect the Roots blower and shorten its service life. Therefore, it is better to build a fan room to effectively control the ambient temperature and protect the three blade Roots blower.
The three blade roots blower can also be used in winter, and can be used in the environment of minus 30 ℃. Pay more attention to the roots blower in winter. Low temperature environment and high temperature environment will damage the roots blower, so we should pay more attention to:
1. Reduce pipeline pressure loss and other pressure loss as far as possible
2. If there is a soundproof cover, the door of the soundproof cover must be opened in summer. The bottom of the sound insulation cover in China does not have any sound insulation effect, but it increases the ambient temperature, resulting in higher temperature of the inhaled air and higher outlet temperature.
3. If Roots blower is installed indoors. Air conditioners can be installed if conditions permit. Don't regret the empty price of electricity. As the temperature of the motor increases by 10 degrees, the service life decreases a lot. Therefore, indoor air conditioning can not only extend the life of equipment, but also reduce the outlet temperature.
4. Outlet temperature of Roots blower=inlet temperature+(10-12) * pressure. The unit of pressure here is meter water column. For example, if the water level is 6 meters, the pipeline is lost and the diaphragm is lost, the pressure loss is 1 meter, and the ambient temperature is 30 degrees, then the outlet temperature will be 100-114 degrees. So from this formula, you can understand the meaning of decreasing inlet temperature and outlet pressure. In summer, the inlet temperature of the fan with sound insulation cover exceeds 45 ℃.
I believe that after reading the above content, you should also have an understanding of the impact of temperature on Roots blower. I hope it will help you.
