What is roots blower used for

Roots blower application‌
‌Roots blowers‌ are widely used in many industries and fields, mainly including:
Sewage treatment‌: In the sewage treatment industry, Roots 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 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 blower maintenance
‌Maintenance of Roots blowers is crucial to ensure their normal operation and extend their service life. Here are some key maintenance steps and precautions:
‌Daily inspection‌:
Check the oil level: Make sure the oil level is within the appropriate range, usually halfway up the oil glass. If the oil level is too low, it should be replenished in time.
Check the tightness of the belt: Check the tightness of the belt regularly to ensure that it is within the appropriate range. Too tight or too loose will affect the operating efficiency of the fan.
Check all connections: Make sure all connections are tight and not loose.
lubricating:
Regularly replace lubricating oil: Roots blowers are usually lubricated with gear oil. It is recommended to replace the lubricating oil after every 1,000 hours of operation and ensure that the oil level is within the appropriate range.
Use appropriate grease: For fans using grease, it is recommended to replenish it every 3 months, and determine whether it needs to be replaced based on the quality of the grease.
‌Cleaning and Filtration‌:
Clean the filter: Clean or replace the air filter regularly to prevent dust and other impurities from entering the inside of the fan. ‌
Clean the imported muffler filter: Clean the imported muffler filter every three months to prevent it from affecting the air inlet volume.
Special Maintenance‌:
Maintenance of water-cooled heat dissipation system: For water-cooled heat dissipation Roots blowers, special attention must be paid to maintenance during seasonal changes. The cooling water circulation must be maintained in summer and the cooling water must be drained in winter to prevent freezing.
Security and performance checks‌:
Check the safety valve: Check the flexibility of the safety valve regularly to make sure it will work properly when needed.
Check the noise and temperature: Closely monitor the noise and temperature of the fan. If there is any abnormality, stop it for inspection in time.
By following the above maintenance steps, you can effectively extend the service life of the Roots blower and ensure its stable operation.
