1. Equipment Composition Description
Each submersible propeller is fully equipped with the necessary accessories, fasteners, spare parts, and cables for safe, effective, and reliable operation, including: a complete submersible mixer; a matching submersible motor; submersible cables for each mixer.
2. Diving Propulsion Device Installation Method
Low-speed flow controllers are submersible and horizontally installed. The controllers can be freely raised and lowered vertically, are easy to move, and can be conveniently removed for inspection or maintenance without anyone needing to enter the pool or well.
Diving Propulsion DeviceFor complete sets, including main equipment, installation system, and lifting device. The installation system consists of square steel rods, top and bottom fasteners, turnbuckles, etc., allowing for free adjustment of the agitator's lifting and lowering, and the agitator can be dismantled and installed without emptying the pool. With the turnbuckles, the guide rails and agitator can be rotated to any angle within a 180-degree range on the platform.The pump is mounted on a motor bracket that slides on the guide rod and functions as a unit. This bracket is designed to bear the entire weight of the agitator and the thrust generated during operation.
The lifting device is portable, installed on the top fixed components of the guide rail system, featuring its ownHoisting sling, equipped with a two-way braking device inside the lifting mechanism. DivingStreaming DeviceSuitable for corrosive wastewater environments. Capable of thoroughly mixing wastewater or sludge, ensuring bottom flow velocity in the tank. The mixer can operate continuously under full immersion conditions. It is also adaptable to continuous operation, intermittent operation (can start up more than 20 times per hour), and can resume operation after a long-term shutdown.
The submersible propeller ensures vibration-free and stable operation. All rotating parts (including the motor) undergo dynamic and static balance tests during manufacturing. This guarantees low maintenance costs, high reliability, and long periods of trouble-free operation for the agitator.
3. Diving Propeller Blade
The impeller is made of fiberglass and features a self-cleaning design with no entanglement due to hydraulic balance. It boasts state-of-the-art hydraulic performance, capable of thorough mixing and propelling the flow of wastewater at the bottom of the pool.
The impeller is fully welded from stainless steel and has undergone dynamic balancing tests. A locking device is installed between the impeller and the shaft to prevent loosening during rotation. The blade design features self-cleaning and anti-vibration functions.
3. Diving Propulsion Axle
The shaft is made of wear-resistant 2Cr13, and the impeller shaft and motor shaft can withstand all axial and radial loads. The impeller is fully protected by mechanical seals, O-rings, and radial seals, completely isolated from the mixing medium, preventing corrosion from occurring.
4. Low-speed Turbulence Promoter Bearings
The propeller shaft of the submersible flow driver is supported by two ball bearings, while the propeller shaft is supported by two cone roller bearings. All bearings are high-quality, maintenance-free types lubricated with long-lasting grease, capable of withstanding both axial and radial loads.
Bearings operate within the range of 0.5Qn < Qn < 1.25 Qn (where Qn is)PricedOptimal operating condition), the bearing life exceeds 100,000 hours.
5. Flow Controller Motor
Submersible motor is a three-phase squirrel-cage induction motor. The motor's protection rating is IEC IP68, insulation class is F, 155°C. SubmersibleThe motor supplied with the flow controller guarantees a rated power to propelThe machine will not overload during operation. The motor can be started 20 times per hour. The motor shaft and rotor have passed dynamic and static balance tests. The motor design is applicable forPlease provide the Chinese content you would like translated into American English.Operates at temperatures up to 40°C (104°F), capable of immersion and continuous stirringPlease provide the Chinese content that needs to be translated into American English.The liquid temperature is up to 40°C, and the average temperature rise of the stator winding does not exceed 80°C. To monitor the temperature on each phase winding, a thermal switch is installed in each phase stator winding coil. The thermal switch is set to activate at 130°C and is connected to the control cabinet, linked to the control relay.
Motors and cables can be continuously used at depths of over 20 meters without losing their waterproof properties (compliant with IP68 protection rating). Submersible motors can be adequately cooled by the surrounding stirring medium without relying on cooling jackets or external cooling systems. Additionally, the motor housing is filled with insulating oil to ensure excellent insulation and cooling performance, and to prevent water leakage and motor damage.
6. Diving Propulsion Thruster Mechanical Seal
In promoting the flowThe hub assembly is equipped with a mechanical seal and two radial seal rings, with the radial seal rings mounted on bronze sleeves, providing additional protection to the mechanical seal and facilitating easy replacement. The shaft seal system includes a sealing oil chamber, where the mechanical seal is installed and operates. The mechanical seal is maintenance-free and can be rotated clockwise or counterclockwise without affecting the sealing function. Made of silicon carbide, the mechanical seal boasts excellent mechanical strength and resistance to thermal shock, with a pH range of 4-10 for the medium.
The design lifespan of the mechanical seal should exceed 25,000 hours.
7. Diving Propulsion Cable and Cable Sealing
Motor comes with a submersible cable, which is a single cable incorporating both control and power cores. Both the motor and the cable are suitable for use in moreCan be continuously used at a depth of 20 meters without losing its waterproof properties.
8. Flowmeter Motor Protection
Temperature Sensor
In the process of streamingThree thermal switches (PTO) are installed in series within the three-phase stator winding to monitor the stator temperature rise. The protection activates at 130°C, initiating the alarm system and stopping the motor.
b. Leak Sensor
Flowmeter settings include a leak sensor to detect leaks in the sealed oil cavity, preventing water from entering the motor and causing damage. The leak sensor is an electrode-type sensor, whose signal can be monitored by a protective relay and an alarm signal will be triggered when water enters the motor.
The submersible low-speed flow driver relay is designed to receive alarm signals from the leakage sensor, and then outputs a fault trip contact to automatically cut off the motor power and stop the motor. Flow driverThe protective relay is installed inside the local control cabinet, and its power requirement is AC220V. The protective relay is included.Flow controllers are provided as a set.
