Many people Roots Blower I don't know much about the technical parameters of. Today, I will take you to know.

1. Technical parameters: pressure

As long as fans are involved, pressure parameters will be involved. Roots blower is different from other types of fans. The pressure parameter of Roots blower is to overcome the resistance of the pipeline, which is often referred to as the back pressure in the industry. This pressure parameter is the main parameter in the selection, and can provide accurate pressure parameters as much as possible.

2. Technical parameters: flow

The flow is the air volume, usually in cubic meters per minute or cubic meters per hour. The flow parameter of Roots blower refers to the volume of gas transported per unit time under standard conditions. The calculation formula is as follows:

Q (inlet)=Q (outlet) × density of outlet gas (kg/m3)/density of inlet gas (kg/m3)

Convert the flow Q (standard, m3/h, normal temperature and pressure) in the standard state into the intake flow Q (inlet, m3/min), which can be calculated according to the following formula:

Q (inlet)=Q (standard) × P (absolute pressure of inlet gas, Pa)/(P (absolute pressure of inlet gas, Pa) - S (relative humidity) × P (saturation pressure of water vapor, Pa)) × T (thermodynamic temperature of inlet gas, K)/273

Note: Standard state: 0 ℃, 0.1MPa dry state

3. Technical parameters: power

Roots blowers produced by each brand are different, so the power of each Roots blower is different. In the Roots blower industry, power refers to shaft power. The higher the shaft power, the higher the efficiency. The lower the shaft power, the greater the loss and consumption. When selecting Roots blower, if there are certain requirements for shaft power, they should be marked in the purchase technical agreement.

4. Technical parameters: medium

Roots blower can only transport clean air, and the transmission medium is mostly air. With the continuous innovation of technology, the current roots blower can also transport gas such as gas and biogas, but it needs special treatment. It should be noted here that the conveying medium here refers to the gas substances passing through the roots blower, which can also be used in the dust removal industry, but the dust will not pass through the roots blower. The roots blower in the dust removal industry provides only the gas source power, which provides power for the dust.

During the selection of roots blower, if the gas medium conveyed contains water gas, oil gas, toxic gas, etc., it needs to be noted. Special treatment must be carried out for the transmission of special gas before the roots blower can be used.

5. Technical parameters: density

When selecting Roots blower, density is rarely mentioned, but another parameter related to density is often heard: altitude, high altitude area, low gas density, low altitude area, high gas density. When selecting Roots blower, if we are in plateau area or basin area, density parameters will play a role, The specific model parameters must be determined according to the gas density.

The above are the technical parameters of Roots blower. I believe you will understand it after reading it. I hope it will be helpful to you.
