Duwan Environmental ProtectionQJBDivingStreaming Device Performance
DivingThe flow diverter must be submersible and horizontally installed; other types of flow diverters are unacceptable. The diverter should be adjustable for up and down movement, easy to move, and should be easily removable for inspection or service without the need for personnel to enter the pool or well.
The潜水propeller is a complete unit, consisting of an installation system and a lifting device. The installation system should be composed of square steel guide rods, top and bottom supports, etc., allowing for free adjustment of the propeller's lifting and lowering, and the propeller can be dismantled and installed without emptying the pool. The propeller is mounted on a bracket that slides on the guide rod as a whole, which must be capable of supporting the entire weight of the propeller and all resulting thrusts. The lifting device should be movable, and the hoist's fixed device must 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 matching hoist hook, lifting chain, and pulley. Each propeller is equipped with a hoist set.
Each unitDivingThe pump should be supplied with cable net sleeves to prevent cable damage caused by fluctuations in the pump's water flow.
All lifting arms should be equipped with installation brackets and lifting devices. AISI 304 stainless steel material. The lifting chain should be made of AISI 304 stainless steel. 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 firm and durable installation of the flow controller system, and expansion bolts should not be used.
Submersible propellers are designed to withstand the corrosive environment of municipal wastewater. They must be capable of propelling wastewater or sludge, ensuring bottom velocity (from the bottom of the pool) Flow rate should not be less than 0.3 m/s (with 300mm as the standard). The pump should operate continuously under full immersion conditions. It should also be capable of adapting to continuous operation, intermittent operation (with a start-up frequency of up to 20 times per hour), and resuming operation after a long-term shutdown.
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 have low maintenance costs, high reliability, and a long period of operation without failure.
