RSR-KS_IA103-F

Product catalog summary

Overview: The Tsurumi RSR-KS series rotary air blowers feature a 3-lobe spur rotor, designed for corrosion and heat resistance, durability, low noise, low vibration, ease of maintenance, and high efficiency, ensuring stable and smooth operation over long periods.

Product Lineup: The series includes air-cooled models with discharge bore diameters from 50 to 300 mm and water-cooled models from 80 to 350 mm. They cater to low pressure (0.6 kg/cm² or less) and high pressure (0.6 to 0.8 kg/cm²) applications, with special specifications for pressures above 0.8 kg/cm².

Applications: These blowers are suitable for aeration in wastewater treatment, agitation of wastewater and sewage, decomposition and scum prevention, and oxygen supply at fish farms. Tsurumi also offers complementary water treatment equipment like submersible pumps, aerators, mixers, scum skimmers, bar screens, and dehydrators.

Technical Specifications:

Rotor: 3-lobe spur rotor for high efficiency and reduced noise and vibration.
Casing: Designed to minimize noise and enhance efficiency.
Side Cover: Supports the bearing and allows leaked compressed air to exit, with cooling water in water-cooled models to prevent temperature rise.
Shaft: Made of precision-machined carbon steel for durability.
Timing Gear: Made of chromium molybdenum steel for stable power transmission and reduced friction noise.

Accessories:

Standard: Includes common base, suction silencer with air filter, discharge silencer, belt cover, flexi check or expansion joint, pressure gauge, safety valve, pulley, V-belt, anchor bolts.
Optional: Anti-vibration rubber, indoor use drip-proof motor.

Selection and Performance: The selection chart helps choose the appropriate blower model based on bore size, revolutions, discharge pressures, air flow rates, and shaft power. Models with smaller numbers are cost-efficient, while larger numbers reduce noise. Performance curves and selection charts detail air volume and discharge pressure relationships.

Special Specifications: Options include electroless nickel plating and an all-stainless steel version of the blower.

Specifications: Specifications for Tsurumi pumps and wastewater treatment equipment include motor outputs from 0.4 kW to 250 kW, discharge bore diameters from 50 mm to 350 mm, and models like RSR2-300WKS. Standard operating conditions are 20°C temperature, 101.3 kPa absolute pressure, and 70% relative humidity.

Procedures: When selecting a motor, choose one with a 10 to 20% margin above the required power. For blowers with discharge bore diameters of 80 to 250 mm, a 3-lobe spur rotor can be replaced with a helical rotor as an option.

Norms and Recommendations: For operations at 0.9 kg/cm² (88.2 kPa), larger models may be needed, and users should contact their dealer or Tsurumi representative. Specifications and designs are subject to change without notice.

Key Data from Tables: Tables provide dimensions and weights for various models, including air-cooled and water-cooled types, and list treating capacities and motor outputs for different series, such as the MDQ/MDC/JD series with a treating capacity of 3-216 kgDS/h and motor outputs of 0.6-3.15 kW.

Additional Information: Tsurumi offers a comprehensive package of pumps and wastewater treatment equipment, including dehydrators and bar screens with specific motor outputs and bar spacing.

Blower with 3-lobe Spur Rotor Installation Diagram Rotor The 3-lobe spur rotor is designed for corrosion resistance, heat resistance and durability, in addition to low noise, low vibration and high efficiency operation. Casing Fluid is drawn from the inlet on the upper stage and discharged from the side on the lower stage. This structure reduces noise and provides higher efficiency. Side Cover The side cover supports the bearing and is structured to allow compressed air that has leaked via the shaft to flow out of the casing, without intrusion into other components. With water-cooled type blowers,...
