Structural description of submersible thruster

Structural description of submersible thrusterThe submersible thruster is mainly composed of submersible motors, reducers, blades, bearings, installation systems, etc. Widely used in oxidation ditch pushing, biochemical tank stirring, and submersible thrusters with a direct connection structure, low energy consumption, and high efficiency. The reducer adopts cycloidal pinwheel reducer or gear reducer, equipped with low power, low speed, large impeller diameter, and wide service area. The impeller is made of polyurethane material and aluminum alloy (some also use fiberglass material), with high strength and strong corrosion resistance. In addition to its stirring function, it also has the functions of pushing and creating water flow. So it is also applicable to river antifreeze and landscape water circulation.

Structural description of submersible thruster

motor

The submersible thruster adopts a fully submerged squirrel cage induction motor, and the insulation level of the submersible motor isFGrade, protection levelIP68，

Reducer:

The submersible thruster reducer is divided into two types: cycloidal and gear, and the appropriate reducer can be selected according to the user's requirements

blade

The submersible thruster has a large blade diameter and a swept back banana shaped blade design. The blades bend backwards and have automatic cleaning function. The material is made of polyurethane or fiberglass, with high strength and corrosion resistance. The blades are fastened to the motor shaft with nuts, making them easy to disassemble and replace during lifting and maintenance.

bearing

The motor shaft of the submersible thruster is supported by two bearings, which are double row ball bearings; And the main bearing is a double row spherical roller bearing; The impeller shaft is supported by a double row angular contact ball bearing and a cylindrical roller bearing; The operating life of the bearing of the impeller is long60000Hour.

Install the system

The installation system of the submersible thruster can be quickly installed and disassembled without the need to discharge sewage from the pool. Pool depthH<4mWhen usingIType installation system, pool depthH>4mWhen using, adoptIIType installation system. When ordering products, users need to provide pool depth and pool type drawings. The installation system is generally made of stainless steel or carbon steel,
