Stainless steel submersible thruster manufacturer, low-speed thruster model selectionSubmersible thruster is an important equipment in the field of sewage treatment, mainly used to create low tangential flow water flow, promote processes such as nitrification, denitrification, and phosphorus removal. ‌

Core functions:

Mixing and stirring: suitable for mixing solid-liquid media to prevent sludge sedimentation. ‌

Low speed thrust flow: specially designed for hydraulic circulation, with uniform flow field distribution and wide range of action. ‌

Applicable scenarios:

Wastewater treatment process: widely used in structures such as activated sludge tanks, oxidation ditches, AAO tanks, aeration tanks, and anaerobic tanks. ‌

Water maintenance: used for water circulation and oxygenation in landscape water areas to prevent suspended solids deposition. ‌

Industrial process: Used for water circulation and creating water flow conditions in industrial and urban wastewater treatment plants. ‌

Working conditions:

The temperature of the medium usually does not exceed 40 ° C, and the pH value is between 5-9. ‌

The liquid density does not exceed 1150kg/m ³, and the maximum diving depth generally does not exceed 20 meters. ‌‌

Prohibited from use in flammable, explosive, or highly corrosive environments. ‌

Technical specifications and model specifications

The performance parameters of the equipment directly determine the processing effect, and when selecting, special attention should be paid to power, speed, and impeller size. ‌

Model naming convention:

Taking 'QJB1.5/4-1800/2-42' as an example, QJB represents submersible thrusters, 1.5 represents motor power (KW), 1800 represents impeller diameter (mm), and 42 represents rated speed (r/min). ‌

In the material code, P represents polyurethane, S represents stainless steel, and AL represents aluminum. ‌

Main technical parameters:

Power consumption: The range is usually 0.37-15KW, and the low-speed thrust series commonly uses 1.5-7.5KW

Impeller diameter: The low-speed thrust series is usually between 1100-2500mm, with the 1800mm specification widely used. ‌

Speed range: usually below 60r/min, common range is 35-115r/min, and the mixing mixer speed can be higher. ‌

Protection level: Motor insulation level F, protection level IP68, can operate underwater for a long time. ‌

Structural composition:

Submersible motor: adopting F-class insulation, with a protection level of IP68. ‌

Gearbox reducer is recommended for blade diameters exceeding 2 meters. ‌

Impeller system: The swept banana shaped blade has self-cleaning function and is made of polyurethane or fiberglass. ‌

Installation system: including suspended guide rails or steel expansion bolt fixing devices. ‌
