Submersible flow boosters are designed to withstand the corrosive environment of municipal wastewater. They must be capable of propelling the flow of wastewater or sludge. Ensure Bottom Flow Rate（From the bottom of the pool 300mm as standard）Not less than 0.3m/sThe transmitter should operate continuously under full immersion conditions. It should also be capable of adapting to both continuous and intermittent operation.(Hourly activation countTo be achieved 20 times)Operational status following a long-term shutdown and subsequent restart.
Diving at Low SpeedThe pump must operate smoothly without vibration. All rotating components (including the motor) should undergo dynamic and static balance tests during manufacturing. The pump should be cost-effective for maintenance, highly reliable, and operate without failure for an extended period.

Control of Submersible Propeller Drives
The operation of the submersible thrusters is via on-site manual control. Two Methods of PLC Automatic Control.
1. Manual Control
Submersible thrusters should be equipped with manual control, ensuring operability even when automatic control is not achievable.Achieve manual control. That is: when the control panel on the cabinet is...“Selector switch”At the manual control position, the machineThe operation can be manually executed through on-site control switches, with the handle control buttons allowing separate control of the equipment's operation.
2. Automatic Control
Please provide the Chinese content to be translated. In PLC automatic operation mode, the submersible propeller is automatically controlled by time. The submersible mixer operates continuously or intermittently.
When the switch is set to the fully automatic control position, the machine can operate in the following ways.
(1) Through the startup button on the control panel. (2) Through the time control on the control panel.
On-site Control Box for Submersible Mixers
Field Control Box for Equipment MatchingMeet all design specifications and comply with IEC Standard or Equal to Standard IEC StandardStandard; meets local climatic conditions.
Each set of dive thrusters is equipped with a local control box. The requirements for the on-site control box are as follows:
（In addition to the internal buttons and signal lights, 35 additional terminals are included.
（2) Order converters for motor protection with the equipment as a set.
（3) The start/stop button should have two contacts, and the stop button (with a mushroom head) should remain in the pressed position.
（(4) To ensure a seamless connection between the on-site control box and the entire plant's control system, the terminal blocks within the control box are fitted with Wiedemann products.
（Cable connectors included.
（6) Protection Class: IP65.
