QJB Submersible Propeller CAD Installation Diagram
Low-speed propeller main components should meet the following material requirements:
Jiangsu Du'an Environmental Protection should be in accordance with the customer's on-site usage.Pool shape and water depth, adjust the propeller installation position reasonably, and provide drawings and performance curves.
Underwater Propeller2-blade impeller) for low-speed.
During the operation of the underwater propeller, it is required that the horizontal flow velocity at the bottom of the pool be greater than0.3 m/s to prevent sedimentation.
The underwater propeller should be capable of moving up and down along the guide rod, allowing for smooth elevation and descent, and should be adjustable in both horizontal and vertical directions, equipped with a safety braking mechanism.
B. Submerged Propeller Structure
a propeller
Underwater propellers should utilize axial flow impellers with excellent self-cleaning capabilities, no vibration during operation, and optimized design, having been tested for dynamic balance. The impeller should efficiently stir and propel the fluid at the bottom of the pool. All blades should have the same shape.
The underwater propeller should be a hydraulically balanced, non-clogging, trailing edge design.
The propeller and shaft are keyed and fixed at the shaft end, with sealing applied. The impeller and shaft must be equipped with a locking device to prevent loosening, whether the impeller and shaft are rotating clockwise or occasionally reversing.
Propellers should undergo dynamic and static balancing tests.
The underwater propeller should be coaxial with the motor.
The shaft of the underwater propeller must be an extension of the motor shaft.
Ball bearing
All bearings are designed for a lifespan of100,000 hours.
Mechanical Seal
The underwater propeller should be equipped with a double mechanical seal system. The seals operate within an oil cavity, which lubricates the overlapping sealing surfaces at a constant flow rate.
DC motor
The motor for an underwater thruster should be a submersible motor, with the insulation level of the stator winding and the stator lead-in beingInsulation temperature of H class: 155°C, motor protection rating: IP68.
The motor should be designed for continuous mixing operation.40°C medium, starts 10 times per hour. To monitor the temperature on each phase winding, a thermal switch should be installed in the stator input coil, which can be connected to the motor overload protection and the control cabinet.
Installation method for Duwan Environmental's QJB Low-Speed Submersible Propeller, including the following steps::
(1)Separately fitted leading rods4Fixed plate below the center44With auxiliary guide rodIBottom fixed plate15Assembled with fasteners onto the stabilizer5Up, to the main rod4And auxiliary guide rodIVertically positioned, viewed from above, the three guide rods form a triangular pattern; two auxiliary guide rodsIWith the leading rod4Arranged symmetrically around a central axis, forming an isosceles triangle when viewed from above, with the main rod being the longest.4Location at the vertex;
(2)Bracket3Horizontally mounted, bracket3Support rod32PCB Connector31With the master rod4Top connector board43Connect, auxiliary rod34Connection plates at both ends and two auxiliary guide rodsITop connector plate14Connect separately. Such bracket3Here you go: Just as presentedTThe character is fixed on three guide rods.
(3)Lift the rod and bracket assembly into the pool using the hoisting system and adjust it to the proper position.
(4)Separately fitted leading rods4And auxiliary guide rodIThe top fixed plate is secured to the pool wall with expansion bolts.
(5)Lift the main body of the submersible jet with the crane system2The main body of the diving propeller2Slide sleeve onto the master rod4The guide rod42Lower gently onto the bracket3Up, Diving Propulsion Unit Body2Fixed to the bracket3Up, the main body of the diving propeller2Level set.
(6)Plug in the power, start the motor, and the desired airflow effect is achieved.
In the system composed of the above three guide rods, the upper fixed plate on the guide rods is secured to the pool wall, and the lower fixed plate is secured to the stabilizer.5The design ensures that all structural components form a solid unit, effectively resisting the backward axial thrust and torque forces experienced during the operation of the submersible propeller, thereby ensuring its long-term safe and reliable operation.
In the system composed of the above three guide rods, due to their small cross-section, the resistance to the flow of wastewater is very low, thereby ensuring the normal operation of the process.
