Key Applications
- Sludge Suspension in Biological Tanks: Ideal for providing critical mixing in EQ tanks, anaerobic, anoxic, degassing, and nitrification/denitrification tanks. The large-diameter hydrofoil impeller generates powerful vertical circulation to permanently prevent sludge sedimentation.
- Fluctuating Flow Adaptability: With its ultra-low head loss and superior fluid dynamics, the mixer is highly adaptable to flow rate fluctuations and diverse tank scales, making it an incredibly versatile solution for varying plant sizes.
Frequently Asked Questions
What are the lubrication and maintenance requirements for the drive system?
The gearbox utilizes an oil-bath lubrication system requiring 220# gear oil, while the housing bearings are grease-lubricated. An initial oil change and internal flush are mandatory after the first 8-10 days of operation. Following this, routine oil changes should be performed every 3 to 6 months, with shorter intervals required in high-temperature or high-humidity environments.
Are there specific environmental restrictions for installing this mixer?
Yes. The installation site must not exceed an altitude of 2,000 meters (6,561 ft), and the relative humidity must stay below 90% at 25°C (77°F). The operating environment must be non-explosive and completely free of corrosive gases and conductive dust. Additionally, weather protection is required to shield the equipment from rain, snow, and water vapor.
