Duwan Environmental ProtectionQJBDivingPusher PerformanceNote:

DivingThe pump is a submersible, horizontally installed model.Matching guide rods,AType bracket and lifting device installation and useThe flowmeter can be raised and lowered, offering easy mobility, and can be conveniently removed for inspection or service without anyone needing to enter the pool or well.

The submersible flow accelerator is a complete set, including an installation system and a lifting device. The installation system should consist of square steel guide rods, top and bottom supports, etc., allowing for free adjustment of the flow accelerator's lifting and lowering, and the ability to disassemble and install the flow accelerator without draining the pool. The flow accelerator is mounted on a sliding bracket that can move along the guide rod as a unit, which must be capable of supporting the entire weight of the flow accelerator and all the resulting thrusts. The lifting device should be portable, and the hoisting frame's fixed device should not be installed on the pool wall or poolside work platform; it should be mounted on the top support of the installation system, and should include a special hoisting hook, lifting chain, and pulley. Each flow accelerator is equipped with a set of hoisting frames.

EachDivingThe pusher should be supplied with a cable net sleeve to prevent cable damage caused by the fluctuation of the pushed water flow.

All crane booms equipped with mounting brackets and lifting devices should be AISI304 Stainless steel material. The lifting chain should be made of stainless steel.AISI304 Materials. Bolts, nuts, washers, rotating operation handles, and anchor bolts should also be supplied as a set. The installation of anchor bolts must use chemical bolts to ensure a sturdy and durable installation of the pump installation system; expansion bolts are not permitted.

Submersible pump flow distributors are designed to withstand the corrosive environment of municipal wastewater. They must be capable of propelling wastewater or sludge flow, ensuring a consistent bottom velocity (distance from the bottom of the pool) 300mm Please provide the Chinese content to be translated.0.3m/sThe streamer should operate continuously under full immersion conditions. It should also be adaptable to both continuous and intermittent operation (with the ability to start up as many as several times per hour).20 Post-shutdown and restart operation status.

Low-speedThe pump must operate smoothly without vibration. All rotating components (including the motor) should undergo dynamic and static balance tests during manufacturing.DivingThe streamer boasts low operation and maintenance costs, high reliability, and a long period of trouble-free operation.
