roots pump

roots pump working principle
The working principle of Roots blower can be simply summarized into the following steps:

• Suction stage: When the rotor rotates, the volume of the chamber gradually increases, forming a low-pressure area.This low-pressure area attracts outside air into the chamber.
• Compression stage: As the rotor continues to rotate, the volume of the chamber gradually decreases.This process causes the air to become compressed, increasing its pressure.
• Exhaust stage: When the volume of the chamber reaches the minimum value, the compressed air will be discharged from the chamber.At this time, the rotation of the rotor will increase the volume of the chamber again to prepare for the next round of suction.
• By repeating the above steps, the Roots blower can continuously suck in, compress and discharge air.This working principle enables Roots blowers to produce high-pressure, high-flow airflow.

roots blower uses

• In the environmental protection industry, it is used in aerobic tank aeration, sedimentation tank mixing, ozone generator (used as a gas source for high-concentration ozone generators), garbage collection, vacuum cleaner trucks, and wet flue gas desulfurization in sewage treatment. wait. Sewage treatment is mainly used for purification and sediment mixing in water treatment plants. Desulfurization and oxidation is the process of transporting air to the desulfurization tower to accelerate the oxidation of ammonium sulfite into ammonium sulfate. Sewage treatment and flue gas desulfurization are generally done by environmental protection projects and environmental equipment companies responsible for desulfurization, denitrification and sewage treatment.
• In the aquaculture industry, it is used to provide oxygen in the water of fish ponds for various fish and crabs, and is also used in aquariums and live fish tanks. (Various large-scale farming of Penaeus vannamei, sea cucumbers, fish, etc.)
• In the pneumatic conveying industry, it is used for grain conveying and dilute phase conveying of powder and granular materials. The fan is used as a low-pressure air source in the form of gas conveying to transport wheat, calcium powder, fly ash, coal dropped from the unloader. Powder, baking soda, cement, flour, bauxite, alkali powder, ammonium phosphate, potassium chloride and other materials. Granular and powdery raw materials such as polyethylene, polypropylene, PE, PP, and urea are transported to the terminal receiving bin. (Inhalation type can also be used). Central feeding system used in injection molding, blister molding, and rotational molding industries to transport raw materials to different equipment. Used in vacuum feeding system and used as negative pressure suction.
• In the mining and metallurgical industries, it is used for coal preparation and flotation by jigging method and air dense medium method. Underground gas extraction, boiling furnace air supply, iron ore particle transportation, ironmaking furnace air supply, metallurgical furnace slag suction, coal washing machine, flotation machine supporting, etc.
• In the building materials industry, it provides blasting for cement vertical kilns, feeds coal to cement rotary kilns, homogenizes cement raw materials, homogenizes raw materials with coal and homogenizes cement. Atomization of fuel in ceramic kilns, magnesia kilns and glass tank furnaces, adsorption of flat glass, molding of glass products and light bulbs, and dehydration of calcium weight plates.

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.
