Diesel electric dual-purpose Roots blower | Diesel engine driven Roots blower

The Chenggu Diesel electric dual purpose Roots blower from Shandong Chenggu is designed to extend the usage environment of CGSR series Roots blowers to a greater extent. Dual use of diesel and electric refers to the use of both diesel engines and electric motors for driving, and this type of fan also requires customization. For areas with inconvenient power connection, consideration may be givenDiesel electric dual-purpose Roots blower | Diesel engine driven Roots blower.

Shandong Chenggu CGSR series Roots blower belongs to the positive displacement rotary fan, ChengguDiesel electric dual-purpose Roots blower | Diesel engine driven Roots blowerThe main sources of power are electric motors, diesel engines, or hybrid electric and diesel engines. The main parameters selected include air volume, pressure, speed, and motor power.

The knowledge I want to share with you today is its working principle. This article will explain in detail the working principle of Roots blowers from the aspects of their structural form, working principle, and precautions.

　　1Structural form

A typical three bladed Roots blower consists of two main parts: the driver and the head. The driver is the power source of the blower, which can be an electric motor or a diesel engine. The head is the main working component of the Roots blower, which operates regularly to achieve gas delivery.

To understand the working principle of a Roots blower, it is necessary to have a thorough understanding of the head structure of the Roots blower. The main components of the head include wall panels, casing, active impeller, passive impeller, active and passive gears, main and auxiliary oil tanks, bearings, etc. In order to provide a clear understanding of the structure of the Roots blower, a structural diagram has been compiled for your reference, as shown below:

　　2Working principle

The Roots blower has two impellers, which rotate towards each other under the drive of the motor. When the impellers pass through the air inlet, a sealed chamber is formed between the two impellers, the wall panel, and the casing. The impellers continue to rotate, and the air inside the sealed chamber is pressed into the exhaust outlet. This process repeatedly passes through the air inlet and exhaust outlet, delivering the outside air to the destination.

There will be certain gaps between impellers, impellers and wall panels, and impellers and casings, which have fixed standards and errors. If the error is too large, it will cause other corresponding fault problems. When the impeller passes through the exhaust port, under the pressure in front of the pipeline, some gas will leak to the outside through the gap, which is called internal leakage.

The specific working principle and process of Roots blower are shown in the following figure:

　　3Precautions

Roots blower is a positive displacement fan, so after operation, the air volume will not change significantly. When there is a slight change in the front pressure, it can continue to deliver air.

After long-term use, the air volume of Roots blower will change, mostly due to a decrease in air volume. The main reason for this is that the clearance between impellers, the clearance between impellers and wall panels, and the clearance between impellers and the casing have changed, resulting in increased internal leakage and affecting the air volume of Roots blower.

In order to ensure the normal operation of the Roots blower, other components of the blower also play a very important role, such as bearings, gears, etc. Any abnormal failure of the cooperating components can have a significant impact on the operation of the blower. So, in the later use and maintenance, not only should important components be carefully maintained, but other cooperating components should also be regularly maintained!
