Overview

The technical parameters of the high-efficiency submersible agitator in the biochemical pool are a direct coupled stamping structure, using multi-stage motors and blades formed by stamping, with good precision, high efficiency, compact structure, small volume, light weight, easy operation and maintenance, and long service life. The push flow mixer adopts a dual mechanical seal structure and a lip seal structure, and the mechanical seal ensures reliable operation within 15000 hours without the need for replacement; The outlet cable of the flow mixer adopts YZW type rubber sheathed flexible cable or other cables with the same performance as GB5013.2. The standard configuration length for a single unit is 10m. The cable sealing head is treated with special vulcanization to prevent damage to the cable sheath and water leakage to the motor.

生化池高效潜水搅拌器技术参数

The installation of the casting type hydraulic mixing mixer is convenient, and the performance of the electric motor and its auxiliary equipment meets the process requirements. The design life of the reducer transmission device is not less than 75000 hours, and the equipment runs for no less than 4000 hours without mechanical problems; It can operate continuously, intermittently, and resume operation 24 hours a day under full immersion conditions of the motor.

The bearing life of the submersible mixer shall not be less than 100000 hours, and the overall service life of the machine shall not be less than 10 years.

The motor and propeller of the submersible mixer are directly connected and can withstand all axial and radial loads.

The cable adopts YCW oil resistant rubber sleeve cable, and the cable seal adopts special vulcanized rubber joints.

The principle of ensuring complete supply and meeting installation and operation requirements is to ensure that the motor has sufficient rated power during installation, height, and operation (within the scope of supply). When the mixer operates at any point on its characteristic curve, the motor will not overload.

The characteristic curve of the push flow mixer, the P-Q curve of the mixer, meets the design requirements.

The "P-Q" characteristic curve of the submersible mixer is stable within the working range and there should be no motor overload phenomenon.

The hydraulic mixer operates smoothly, flexibly, without vibration or abnormal noise throughout the entire operating conditions.

The submersible mixer is designed and manufactured for 24-hour continuous full load operation, with a temperature rise of no more than 35 ℃ for the motor, bearings, and sealing structures, and no overheating or deformation.

The components should have sufficient strength, stability, and stiffness, and be suitable for the operating conditions of this installation, as well as sufficient space and facilities for maintenance and adjustment.

When the submersible mixer operates at a high speed under any operating condition on the performance curve, it shall not exceed the rated value and coefficient on the motor nameplate.

When there is actual demand, it can operate at overload (able to withstand at least 10% overload).

Keep sewage and sludge in a suspended state in the tank, prevent sedimentation, prevent particles from settling on the tank walls and bottom, and maintain flow.

The on-site control box is designed or requested by the user, and a matching control box is provided on site Reserved PLC central control signal port
