Roots blower is a positive displacement rotary blower, the main power source for the motor, diesel engine or motor diesel hybrid, the main parameters of selection are air volume, pressure, speed, motor power, etc., today to share with you the knowledge is its working principle, this article will from the Roots blower structure form, working principle, precautions and other aspects, explain the working principle of Roots blower in detail.

    An ordinary three-lobe roots blower is mainly composed of two parts: the driving machine and the head, the driving machine is the power source of the blower, can be a motor can also be a diesel engine, the head is the main working component of the roots blower, through regular operation to achieve the purpose of gas transmission. In order to understand the working principle of roots blower, we must first fully understand the structure of roots blower head. The main components of the head are: wall panel, housing, active impeller, driven impeller, active driven gear, main and auxiliary fuel tanks, bearings, etc.

    The roots blower has two impels, driven by the motor, the two impels will rotate opposite each other, when the impeller turns the air intake port, a sealed chamber will be formed between the two impels and the wall panel and the casing, the impeller continues to rotate, the air inside the sealed chamber will be pressed into the exhaust port, so repeatedly through the air intake and exhaust port, the outside air will be transported to the destination.

   There will be a certain gap between the impeller and the impeller, the impeller and the wall panel, the impeller and the casing, and the gap has a fixed standard and error, and too much error will cause other corresponding problems. When the impeller passes through the exhaust port, under the action of the pressure in front of the pipeline, part of the gas will leak to the outside world through the gap, such a leak, we call it internal leakage.

    Roots blower is a positive displacement blower, so after running up, the air volume will not change, and when the current pressure changes slightly, it can continue to carry out air transportation. After long-term use, the air volume of roots blower will change, mostly reduced air volume, the main reason is: the gap between the impeller and the impeller, the gap between the impeller and the wall panel, the gap between the impeller and the housing has changed, resulting in an increase in internal leakage, and then affect the air volume of roots blower. In order to ensure the normal operation of the roots blower, other components of the roots blower also play a very important role, such as: bearings, gears, etc., the abnormal failure of the components with the work will also have a great impact on the operation of the blower. Therefore, in the later use and maintenance, not only the important components should be carefully maintained, but other components should also be regularly maintained!
