How to Select an Oxidation Ditch Low-Speed Impeller
Selection Methods for Submersible Flow Pumps
Diving Propulsion DeviceComplete set, including installation system and lifting device. The installation system should consist of square steel guide rods and top and bottom supports, allowing for free adjustment of the pusher's lifting and lowering. The flow controllers can be disassembled and installed without draining the pool. The flow controllers are mounted on a bracket that slides along the guide rod, acting as a single unit. The bracket must be able to bear the entire weight of the flow controller and all the thrust it generates.
The lifting device should be portable, and the hoisting frame's mounting device must not be installed on the pool wall or the poolside work platform. It should be mounted on the top support of the installation system, and should include a stainless steel lifting hook, lifting chain, and pulley.
Each streamer should be provided with a cable tensioning component and a cable clip to prevent cable damage caused by fluctuations in the stirred water flow.
Lifting arms equipped with mounting brackets and lifting devices should be made of AISI 304 stainless steel. The lifting chain should be of AISI 316 stainless steel material. Bolts, nuts, washers, rotating handles, and anchor bolts should also be supplied as a set. Anchor bolts must be installed using chemical bolts to ensure a secure and durable installation of the flow controller system; expansion bolts are not to be used.
Submersible flow propellers should be capable of adapting to the corrosive environment of municipal wastewater. They must be able to propel wastewater or sludge flow. Ensure Bottom Flow Rate（Apologies, but there is no Chinese content provided to translate. Please provide the text you would like translated into American English. 300mm as standard）Not less than 0.3m/sThe streamer should operate continuously under full immersion conditions. It should also be adaptable to both continuous and intermittent operation.(Increased startup frequency per hourTo be achieved 20 times)The status of resuming operations after a long-term shutdown.
Submersible low-speed flow generators must operate smoothly without vibration. All rotating components (including the motor) should undergo dynamic and static balance tests during manufacturing. The flow generator should be cost-effective for operation and maintenance, highly reliable, and have a long period of trouble-free operation.
