Duwan Environmental's QJB Submersible Flow Generator Controller

The operation of the submersible propellers is via local manual control. Two methods of PLC automatic control.

Manual control

The dive propeller should be equipped with manual control, allowing operation even when automatic control is not achievable.Achieve manual control. That is: when the control panel on the cabinet“Selector switch”Placed in manual control position, the machineManual operation is available on-site through control switches, with handle control buttons for separate operation of the equipment.

2. Automatic Control

Please provide the Chinese content you would like translated into American English. Under PLC automatic operation, the submersible propeller is controlled automatically 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 modes.

(1) Through the start button on the control panel. (2) Through the time control on the control panel.

Low-speedDivingStreamingField control box for equipment

Field control box for equipment outfittingMeet all design specifications, while complying with IEC Standard or higher than standard IEC StandardNational Standards; meets local climatic conditions.

Each set of dive thrusters is equipped with a local control box. The specifications for the on-site control box are as follows:

（1) In addition to the internal buttons and signal lights, 35 terminals are included.

（2) Order converters for motor protection and equipment as a matched set.

（3) The start/stop button should have two sets of contacts, and the stop button (with a mushroom head) should remain in the pressed position.

（4) To ensure a seamless connection between the field control box and the entire plant control system, the terminal blocks within the control box are fitted with Weidmüller products.

（5) With cable connectors.

（6) Protection Level: IP65.

（7) Reserve PLC interfaces; each unit requires control from both the local control cabinet and the central control room.

（8）Material of on-site control box: outdoor use 304 Stainless steel, carbon steel coated for indoor use, housingThe color is determined by Blue Deep Group.

（9) Components in the control box are from ABB, Schneider, Siemens, or equivalent brands.
