Introduction to the basic working principle of Roots blower Roots blower is a centrifugal fan with positive suction and positive blowing, also known as Roots blower. Compared with ordinary centrifugal fan, it has higher pressure, smaller volume and larger volume flow. Roots blower is widely used in various industrial fields, including printing, pharmaceutical, chemical, water treatment, water, electricity, etc. It is mainly used for air transmission, gas pressurization, waste gas treatment, etc.

The operating conditions of Roots blower mainly include the following aspects:

1. Temperature: Roots blower is applicable to the working environment with medium temperature between - 20 and 80. For high-temperature media, high-temperature resistant materials can be used for transformation or heat dissipation measures.

  2. Pressure: Roots blower can provide a higher pressure, usually within the working range of 0.1~0.8MPa. For applications requiring higher pressure, it can be achieved by increasing the number of stages or by using multiple units in series.

3. Flow: Roots blower has a wide flow range, and different flow can be designed according to the user's needs. Generally speaking, the flow range of Roots blower is 0.1~100m ³/ Min.

4. Medium: Roots blower is suitable for dry and clean gas medium. For gas medium containing dust, particles and high humidity, corresponding filtering device or wet processing equipment shall be equipped to protect Roots blower.

5. Speed: The speed of Roots blower is generally between 500~3000 rpm. Different speeds can be selected according to the needs of different occasions.

6. Power: Roots blower usually has a large power, and appropriate motor power needs to be selected according to different gas medium, flow and pressure requirements.

Noise and vibration: Roots blower usually produces certain noise and vibration. When selecting the installation location, it is necessary to consider the impact of noise and vibration on the surrounding environment and equipment, and take corresponding sound insulation and vibration reduction measures.

When using Roots blower, pay attention to the following points:

1. Regularly check and maintain Roots blower, including cleaning the dust inside and outside the blower, lubricating the bearing, and checking the sealing condition.

2. It is forbidden to disassemble or replace parts during normal operation of Roots blower to avoid failure or safety accident.

3. When operating Roots blower, ensure that the temperature, pressure, humidity and other parameters of the supplied gas are within the specified range.

4. Pay attention to the start and stop process of Roots blower and avoid frequent start and stop and sudden stop to reduce damage to equipment.

5. When using Roots blower, pay attention to the layout and smoothness of its exhaust outlet and inlet to avoid affecting the normal operation of the blower.

In short, Roots blower is a widely used centrifugal fan, which has important applications in many industrial fields. When using Roots blower, it is necessary to consider various service conditions and precautions to ensure the normal operation of the blower and extend its service life.
