Problems solved by technology

[0003]Because the submersible thrusters work under sewage, the working conditions are complex and the environment is harsh, the existing products have defects such as high noise, high vibration, short life and high energy consumption
Especially the large volume and heavy weight are not conducive to lifting and placement, and the cost is high
The reasons for this situation are: most of the submersible flowmakers on the market are cylindrical gear box reduction mechanisms, and the connection with the motor is not compact enough. poor effect
In addition, there is no reliable and comprehensive design for water leakage security protection, and the water ingress in the motor and reduction mechanism cannot be predicted and protected in time.

Abstract

A submerged propeller has a directly coupled motor-cycloidal spider driver system consisting of a motor with single-end mechanical seal on its mainshaft, a cycloidal spider type speed reducer with dual-end mechanical seal and multi-lip seal on its output axle, a propeller, and a leakage alarm protecting system for the front and back bearing covers of said motor.

Description

technical field [0001] The invention relates to a motor direct-connected cycloidal star wheel submersible thruster. Background technique [0002] The submersible flowmeter is widely used in the aeration tank in the sewage treatment industry. It has the functions of pushing flow and stirring and preventing sludge settlement. It is an indispensable key equipment for sewage treatment. With the increasing investment in sewage treatment and the popularization of sewage treatment all over the world, the market capacity of this equipment is huge. Manufacturers from all over the world are striving to develop high-tech and highly competitive products to lead the world market. [0003] Because the submersible flowmaker works under sewage, the working conditions are complex, and the environment is harsh, the existing products have defects such as high noise, large vibration, short life, and high energy consumption. In particular, the large volume and heavy weight are not conducive to ...
