The 22kw Roots blower is a mechanical equipment widely used in multiple fields. The following is a detailed introduction to it:
1、 Basic concepts
Roots blower, also known as Roots blower, is a type of volumetric rotary blower. Its working principle mainly relies on the relative motion of two blade shaped rotors inside the cylinder, which compresses and delivers gas through this motion. 22kw refers to the power of the fan being 22 kilowatts.
2、 Main features
1. Stable flow: Roots blower can provide stable gas flow, suitable for situations that require continuous and stable gas supply.
2. Wide pressure range: Roots blowers can adapt to different pressure requirements by adjusting the speed or changing the outlet throttle to meet a wide pressure range.
3. Simple and compact structure: Roots blower has a simple structure, easy manufacturing, and is easy to maintain and upkeep.
4. Oil free pollution: Due to the tightly controlled gap between the two rotors for sealing, the discharged gas is not contaminated by lubricating oil, making it suitable for occasions with high requirements for gas purity.
3、 Application Fields
1. Wastewater treatment: In activated sludge and other wastewater treatment processes, Roots blowers blow air into the aeration tank to provide sufficient oxygen for microorganisms to decompose organic matter in the wastewater, achieving the goal of purifying water quality. At the same time, it can also be used for mixing sewage to improve treatment efficiency.
2. Aquaculture: Roots blowers inject air into the water through an aeration system to increase the dissolved oxygen content in the water, providing a good living environment for aquatic organisms such as fish and shrimp, and improving aquaculture density and yield. In the recirculating aquaculture system, Roots blowers are also used to promote water circulation and maintain stable water quality.
3. Pneumatic conveying: Roots blower can be used to transport powdered materials such as cement, flour, coal powder, as well as granular materials such as plastic particles and grains. The material is mixed with air through a pipeline to form a gas-solid two-phase flow, and the material is transported to a designated location using the airflow pressure generated by a Roots blower.
4. Smelting industry: In ironmaking blast furnaces, Roots blowers provide high-pressure air to ensure the smooth progress of the ironmaking process. In the process of converter steelmaking, Roots blower is used to blow oxygen or oxygen enriched air into the converter to remove impurities and adjust the composition of the molten steel.
5. Chemical industry: Roots blowers can transport and pressurize gases such as hydrogen, nitrogen, chlorine, etc. to meet the requirements of production processes. At the same time, it can also be used to extract air from the packaging container during the vacuum packaging process, creating a vacuum environment.
6. Power industry: In thermal power plants, Roots blowers are used to provide the air required for combustion to boilers, improving their thermal efficiency.
4、 Model and Parameters
There are various models of single-stage three blade Roots blowers suitable for 22kw motors, such as SR125, SR150, SR175, etc. The air volume and pressure parameters adapted to different models of fans are also different. For example, the SR125 model is compatible with an air volume parameter of 12.36 cubic meters per minute (specific parameters may vary depending on the manufacturer and product), and a pressure adaptation parameter of 58.8 kPa; The SR150 model covers a wider range of air volume and pressure parameters.
5、 Price and Market
The price of a 22kw Roots blower varies depending on factors such as brand, model, material, and performance. Generally speaking, fans from well-known brands, high-performance, and high-quality materials are relatively expensive. Meanwhile, market prices are also influenced by factors such as supply and demand, regional differences, etc. When purchasing, it is recommended to choose the appropriate brand and model based on actual needs, and consult multiple suppliers to obtain favorable prices.
6、 Maintenance and upkeep
In order to ensure the normal operation and extend the service life of the 22kw Roots blower, regular maintenance and upkeep are required. Specifically, it includes:
1. Regularly clean the filter screen, cooler, and various components to ensure that there is no dust, oil, or other debris blocking the machine.
2. Regularly inspect the lubrication system to confirm whether the quality and quantity of the oil meet the requirements, and promptly replace or supplement the lubricant.
3. Regularly check the wear level of fasteners, belts, or gears in the transmission device, and replace worn parts in a timely manner.
4. Regularly monitor the temperature and pressure parameters of the fan, promptly detect abnormalities, and take corresponding measures to avoid overheating and overpressure.
5. Regularly check and adjust the tension of the belt, clean the fan oil tank, air chamber, and sealing device, etc.
In summary, the 22kw Roots blower has a wide range of applications and significant economic value. When selecting and using, it is necessary to fully understand its characteristics, parameters, and application scope, and make reasonable selection and maintenance according to actual needs.
