roots type blower

What type of pump is a roots type blower?

• roots type blower is a gas compressor with Roots gear as its main working component. There are two gears running inside the device, and the gap between them is used to extract air or other gases and output them. roots type blower usually consists of impeller, Roots gear, main shaft, cylinder, transmission mechanism, motor and other parts. Among them, the Roots gear is a key component of the blower. It consists of two gears meshing with each other. The gears have a unique shape and can form a series of air accumulation chambers and sealing areas. The support device of the main shaft and Roots gear is installed in the cylinder, which not only ensures the safe operation of the machine, but also reduces the vibration and noise of the blower.

roots type blower uses

‌roots type blowers‌ are widely used in many industries and fields, mainly including:

• ‌Sewage treatment‌: In the sewage treatment industry, roots type blowers are widely used in aeration, stirring, mixing and other aspects to ensure the smooth progress of the sewage treatment process.
• ‌Pneumatic conveying system‌: roots blowers are used to transport feed, lime powder, monosodium glutamate, soybean skin, silica and other powdery materials, as well as grain suction machines or crane suction vacuum pumps in grain transportation to ensure the effectiveness of materials transmission.
• ‌Aquaculture‌: In aquaculture, roots blowers use micropore aeration technology to oxygenate water quality and improve breeding efficiency.They are important equipment in the aquaculture industry.
• ‌Coal chemical industry‌: In the coal chemical industry, roots blowers are used in sewage treatment and different processes, playing an important role in improving production efficiency and product quality‌.
• ‌Dust removal industry‌: roots blowers are also used in the dust removal industry, such as desulfurization, denitrification, dust removal, etc., to ensure the effective treatment of industrial flue gas and waste gas.
• ‌Grain processing, flour mills, food factories‌: used in transportation, drying, cooling, dust and other links to ensure the smooth progress of the food processing process‌.
• ‌Paint and Coating Industry‌: Used for ventilation, dust removal and waste gas treatment to ensure the safety and health of the working environment.
• ‌Mining, quarrying, and mineral processing industries‌: used in emissions, exhaust, gas transportation, drying and other links to ensure environmental control and safety during the development of mineral resources‌.
• ‌Pharmaceutical Industry‌: In the pharmaceutical industry, roots blowers are used in pharmaceutical processing, chemical reactions and other aspects, such as laboratory ventilation equipment, to ensure the safety and efficiency of the pharmaceutical production process‌.

Roots type blower pressure range

• According to different usage requirements, the pressure of the roots blower can be adjusted between 9.8kpa and 200kpa.Within this pressure range, the roots blower can work normally and meet various process requirements.Specifically, the pressure range of roots blowers includes:
• ‌Low pressure range‌: The pressure is lower than 58.8kpa, including 9.8kpa to 58.8kpa.This type of fan usually uses air cooling, and is mostly designed with a single oil tank.
• ‌Medium pressure range‌: The pressure is between 58.8kpa and 98kpa.This type of fan requires water cooling, and most of them are designed with double oil tanks.
• ‌High pressure range‌: When the pressure exceeds 98kpa, especially when it exceeds 140kpa, double-stage pressure boosting technology is required to ensure stable operation of the fan under high pressure.

Roots type blower specifications

What are the different types of roots type blowers?

According to different classification standards, roots blowers can be divided into the following categories:

• 1.Single-stage roots type blower and multi-stage roots blower: Depending on the number of impellers, roots blower can be divided into two types: single-stage and multi-stage. Single-stage roots type blowers have only one impeller and are suitable for low pressure and medium flow applications, while multi-stage roots type blowers have multiple impellers and are suitable for high pressure and large flow applications.
• 2.Fixed roots blower and variable frequency speed-adjustable roots blower: Depending on the driving method, roots type blowers can be divided into two types: fixed type and variable frequency speed-adjustable. The fixed speed of the roots blower is fixed, and the output air volume and pressure cannot be adjusted; while the variable frequency speed-regulated roots blower adjusts the motor speed through the frequency converter to achieve precise control of the air volume and pressure.
• 3.Dry roots type blower and wet roots blower: Depending on the working environment, roots type blowers can be divided into two types: dry type and wet type. Dry roots type blowers are suitable for processing dry gases, such as air, nitrogen, etc.; while wet roots type blowers are suitable for processing gases that are moist or contain liquid particles, such as aeration systems in sewage treatment.
• 4.Standard roots blower and customized roots blower: According to different customer needs, roots type blower can be divided into two types: standard type and customized type. Standard roots type blowers are manufactured according to general specifications and designs and are suitable for general application scenarios; while customized roots type blowers are designed and manufactured according to specific needs to meet special process requirements.
