Duwan Environmental's QJB Low-Speed Flow InjectorTechnical Requirements
(1) General Requirements
A. Jiangsu Du'an Environmental Protection Co., Ltd.Pool dimensions and water depth are carefully considered to determine the optimal installation positions for mixers and flow distributors. The quantity and power of the mixers and flow distributors are verified and confirmed, along with the provision of design drawings and performance curves.
B. Submersible mixers utilize medium-speed propellers, featuring...3 blades with a guide vane.
C. The submersible propeller should operate at a low speed.2-blade impeller.
D. Flow rates and mixing rates are required to be greater than at the bottom of the pool during operation.0.3 m/s to prevent sedimentation.
E. The flowmeter and agitator should be able to move up and down along the guide rod smoothly, with easy adjustment in both horizontal and vertical directions, and be equipped with a safety braking device.
F. Guides and hangers must possess adequate strength and rigidity, with no deformation permitted during the process of the pusher's deployment and removal.
(2) Technical Requirements
A. The submersible propeller features an excellent self-cleaning function, operates without vibration, and incorporates an optimally designed axial flow impeller. The propeller blades are reinforced with polyurethane castings and have undergone dynamic balancing tests. The impeller should effectively stir and propel the fluid flow at the pool's bottom. All blades should have the same shape.
B. The impeller and shaft are connected and fixed at the end of the shaft with keys and sealed. A locking device must be used on the impeller and shaft to prevent loosening, whether they are rotating clockwise or occasionally reversing.
C. The impeller should undergo dynamic and static balance tests..
D. The root of the blade should possess sufficient strength, and no cracking or other issues are permitted under the specified operating conditions.
E. The submersible mixer should be mounted on the same shaft as the motor. The shaft of the mixer's propeller must be an extension of the motor shaft. Couplings will not be accepted.
F. All bearing designs have a shorter service life.100,000 hours.
G. Each mixer 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.
(3) Electric Motor
A. PusherThe motor for the mixer should be a submersible motor, with the stator winding and stator lead insulation rated at F-class insulation with a temperature of 155°C.°The motor features an IP68 protection rating.
B. The motor should be designed for continuous handling of stirring.40°The medium for C starts up 10 times per hour. To monitor the temperature on each phase winding, a thermosensitive switch should be installed in the stator's input coil, which can be connected to the motor overload protection and the control cabinet.
C. Submersible motors and mixers should be manufactured by the same manufacturer. Bidders are required to provide the signal specifications for each of the motor's protective sensors, ensuring the signals can be transmittedMCC。
D. The stator winding of the motor requires the installation of an over-temperature sensor.
E. Install leak detection sensors to prevent liquid from entering the stator windings.
F. The water detection device should be installed in the motor cable junction box.
G. The rated power of the motor should exceed the specified shaft power.1.1 times.
(4) Cable Entry Sealing
A. The cable entry sealing design should be capable of eliminating a certain amount of torque to form a waterproof潜水seal. This seal must ensure the replacement of the cable and cannot be sealed using epoxy, silicone, or any other secondary sealing system.
B. Precautions should be taken to prevent air exchange between the internal and external cables due to temperature differences in the cable joint section.
C. Cables should be properly secured in water, and bidders should provide securing devices.
(4) Electric Control Cabinet
Field Control BoxLanShen GroupSupplied with a transparent double-door control box made of stainless steel.The 304-grade stainless steel is used for both the frame and the bracket, ensuring a sturdy and secure fit. The panel thickness is no less than 1.5mm. The outdoor protection rating is IP55, and the indoor rating is at least IP4X. Inside the box, protective switches, control switches, and logic components are installed. The panel features a multi-functional meter, a conversion switch, start/stop buttons, and an emergency stop button, as well as running indicator lights. The device's operation can be halted in the event of a fault.
LanShen GroupIn accordance with the performance requirements of the provided equipmentOn-siteRegulatory RequirementsProduction配套设施Provide complete electrical control diagrams for each control box, wiring diagrams, general layout of electrical component locations, specific wiring diagram numbering, and a list of electrical component configurations.
