The manufacturer of explosion-proof roots blower explained the reasons for its high temperature? Generally speaking, the normal operating temperature range of Roots blower is generally 60-90 ℃.

The temperature of Roots blower is related to the following factors: the higher the operating environment is, the higher the temperature is, the higher the pressure is, the higher the temperature is, and the higher the speed is, the higher the temperature is.

The outlet temperature of Roots blower is proportional to the pressure. Normally, the temperature will increase by about 1.1 ℃ when the pressure increases by 20kpa, and by 0.9 ℃ when the speed increases by 200.

Calculation method of Roots blower body temperature: room temperature+every 1000 mm water column rise, the temperature rises by 10 degrees. The temperature within this range is normal. If it exceeds, the temperature of Roots blower is too high.

Another is that the larger the Roots blower is, the higher the temperature will be.

The temperature of the same blower produced by different Roots blower manufacturers will be different, depending on whether the adjustment of the clearance between the various parts of the blower is appropriate. The main parts of the blower include bearings, gears, impellers and other important quality advantages and disadvantages.

The higher the temperature of Roots blower exceeds the normal range, the failure or even shutdown of the blower will be caused, and the service life of the blower will be shortened.

2、 Cause of High Temperature of Explosion proof Roots Blower

1. There is too much oil, too thick and too dirty in the oil tank;

2. The filter or muffler is blocked;

3. The pressure is higher than the specified value;

4. The impeller is excessively worn with large clearance;

5. Poor ventilation and high indoor temperature cause high inlet temperature;

6. The running speed is too low, and the belt slips;

3、 What to do if the temperature of Roots blower is too high

1. Lower the oil level of the oil tank to a reasonable position, and replace the oil that is too thick and dirty;

2. Remove foreign matters from the filter and muffler;

　　3. Check the pipeline pressure to reduce the system resistance, such as shortening the pipeline as far as possible, reducing the number of turns and valves, etc., and reducing the pipeline pressure loss and other pressure losses as far as possible. One purpose is to make the pressure not higher than the value specified on the fan nameplate;

4. Repair the clearance of all parts of the fan;

5. Adjust the tension of V-belt to prevent the belt from slipping and increase the speed;

6. The ventilation is smooth. If the Roots blower is installed indoors, pay attention to the smooth ventilation. In summer, the door of the acoustic enclosure can be opened, and if conditions permit, an air conditioner can be installed to reduce the inlet temperature;

7. In case of water-cooled Roots blower, water cooling can be adopted.
