QJBStructure and Performance Features of Low-Speed Turbulator

QJBLow-speed propellers are mainly composed of submersible motors, reducers, spiral propeller blades, seals, hand-cranked winch mechanisms, installation systems, and electrical control devices.

1Tightly structured, compact, and lightweight. Easy to operate and maintain, quick installation, and long service life.

2The blades feature self-cleaning capabilities, preventing debris entanglement and blockage.

3When used in conjunction with an aeration system, it can significantly reduce energy consumption, increase oxygenation levels, and effectively prevent sedimentation.

4、QJBMotor winding for a type low-speed impellerFGrade insulation, protection rating:IP68Selects a single-lubrication, maintenance-free imported bearing with oil chamber leakage detection and motor winding overheating protection, ensuring safer and more reliable motor operation.

5The mechanical seal's friction pair material is corrosion-resistant tungsten carbide, and all fasteners are made of stainless steel.

6Under specified conditions, the mean time to first failure is not less than10000Hourly life span, not less than15Year.

7The propeller blades of the diving propeller are made of elastic polyurethane or aluminum alloy, capable of withstanding variable loads, with thrust evenly distributed.ReasonableHydraulic design.
