The 11 kW Roots blower is widely used in the industrial field. The following analysis is conducted from the aspects of selection parameters, application scenarios, selection points, and maintenance:
1、 11 kW Roots blower selection parameters
Taking the common 100-11kw model as an example, its flow rate is 420m3/h (i.e. 7m3/min), the pressure can reach 50kPa (or 98kPa, depending on the model), the speed is between 1060-1080rpm, and the weight is about 360kg. In addition, there are T series models on the market, such as the T100 model, which has an air volume range of 3.28-9.07m3/min, a pressure range of 9.8-98.8kPa, a power of 3-15kw, a speed of 990-1760rpm, and a weight of 309-377kg. These parameters provide important basis for selection.
2、 Application scenarios
Wastewater treatment: used in aeration tanks to increase oxygen content, promote aerobic bacterial growth, and deeply treat and purify wastewater.
Aquaculture: providing oxygen to meet the survival needs of aquatic organisms, increasing aquaculture density and yield.
Pneumatic conveying: Conveying powdered and granular materials, such as nano calcium, suitable for industries such as chemical and food.
Other industrial applications: can be used for chemical raw material manufacturing, dust removal, desulfurization and denitrification, pulp and printing ink transportation, etc.
3、 Key selection points
Clarify air volume and pressure requirements: Determine the required air volume and pressure range based on specific application scenarios. For example, sewage treatment may require high air volume, low-pressure fans, while chemical plants may require high-pressure fans.
Consider medium and temperature: Select the appropriate fan material and sealing form based on the medium, temperature, and properties processed by the system. For example, when transporting corrosive gases, corrosion-resistant materials such as stainless steel should be selected.
Pay attention to noise and energy efficiency: If there are strict requirements for noise, fans with lower noise levels should be selected. At the same time, pay attention to the energy efficiency ratio of the fan and choose energy-saving products.
Choose well-known brands and reliable suppliers: Famous brands usually have better quality control and after-sales service, which can ensure the stable operation and long life of equipment.
4、 Maintenance and upkeep
Regularly check the tightness: Check the tightness of the connecting bolts of the fan to prevent loosening.
Maintain lubrication: Regularly check the oil level in the lubrication tank, and if it is insufficient, it must be replenished. The lubricating oil of the gearbox should be replaced regularly, and the rolling bearings and shaft seals should also be lubricated regularly.
Monitoring the operating status: Pay attention to whether there are any abnormalities in the operation of the fan, including changes in sound, temperature, and oil pressure, as well as whether the three-phase current of the motor is balanced.
Regularly clean the filter: maintain the normal operation of the air filter to prevent blockage.
Reasonably arrange the operating cycle: In order to extend the service life of the machine, the operating cycle should be appropriately arranged, such as regular replacement of units that operate continuously.
