Roots blower air pressure is not restricted by the fan speed, no matter how the wind speed changes can remain the same. While the air volume is proportional to the fan speed, namely Q = KN
Q: said airflow N: for fan speed K: for coefficient
From the formula, the air volume adjustment, entirely by the frequency converter to change motor to achieve stepless speed change, rise to adjust the effect of air volume. According to the fan of the 15 hz low frequency field application process, usually at around 35 hz, have individual moment 50 hz full airflow run, due to the basic shaft kiln process is consistent, so in different amount of shaft kiln air regulation is basically the same, every shaft kiln application of frequency conversion technology can obtain 40% energy saving effect.
Roots blower a constant torque load, the power saving rate is proportional to the droop or N % = delta N %, though different from general fan and water pump power saving rate is higher, but because of its power is larger, but not bad, as long as the furnace wall is continuous 24 hours work, and start the time also is very long. So electricity saving potential, the high cost of energy saving.
After technical innovation of roots blower, changed the past to adjust export (import) valve opening ways to adjust the production mode of wind pressure or volume, reduce Labour intensity, adjust good timeliness, raised the qualification rate of products, consumption decreased obviously.
Safe operation and service life of the roots blower, often depends on whether the correct maintenance and maintenance, and attention should be paid to any accident to believe, if long time don't use of three leaves roots blowers will be cut off all the power on its body, placed it in a dry and ventilated place, so that it can effectively avoid the body in the long term is not in use and produce the phenomenon such as rust. In addition of roots blower in use process should regularly on the oiling, only in this way can ensure maximum operation flexibility of three leaves roots blowers.
In addition to do so, at ordinary times also note the following:
Roots blower 1. Check whether the fastening of each part and the positioning pin is loose phenomenon, if there are any loose should hold firmly fixed.
2. The fan inside the scale, rust and spalling phenomena cannot exist. To prevent the body's internal oil leakage phenomenon.
3. Remove the machine to machine each dimension measurement, recorded, and marking on parts and direction, so as to guarantee the assembly and can keep the original requirements.
Roots blower 4. Overload sometimes is not displayed immediately, so attention should be paid to the exhaust pressure, bearing temperature, and the change of the motor current, so as to judge whether the machine running normally.
5. Under normal conditions require the unit running 1000 hours of lubricating oil must be replaced. Pay attention to oil cooling condition is normal, pay attention to the quality of the lubricating oil, often listen to have roots blower operation without noise, pay attention to whether the unit work in is not in conformity with the prescribed conditions.
6. The new machine or roots blower after overhaul, according to the steps in operation, suggest 8 hours to replace the whole lubricating oil. Daily maintenance is very important, small fault must repair again after put into use.
