Duwan Environmental QJB Submersible AgitatorMachineThe structure
The Duwan Environmental Protection Technology Department adjusts the installation position of the agitator reasonably based on the provided pond type and water depth, and offers drawings and performance curves.
Submersible mixers require that the horizontal flow velocity at the pool bottom be greater than0.3 m/s to prevent sedimentation.
Submersible agitators should be able to move up and down along the guide rod smoothly, allowing for easy adjustment in both horizontal and vertical directions, and equipped with a safety braking device.
Propeller
Submersible mixers should be equipped with a well-designed axial flow impeller that features excellent self-cleaning capabilities, operates without vibration, and has been optimized. The impeller should effectively stir and propel the fluid movement at the bottom of the pool. All blades should have the same shape.
The submersible mixer propeller should be hydro-dynamically balanced with a non-clogging trailing design.
The propeller and shaft are keyed and fixed at the shaft end, with sealing in place. 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.
2) Bearings:
All bearing designs have a specified service life.Please provide the Chinese content to be translated.Tiny100,000 hours.
Mechanical Seals
The submersible 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 steady flow rate.
3) Electric Motors:
The motor of the submersible mixer is a submersible motor.All-copper coil motorStator winding and stator lead-in insulation grade:Insulation temperature of H grade is 155°C, the motor's protection rating is IP68.
The motor should be designed for continuous operation in a blending process.40℃ medium, starts 10 times per hour. To monitor the temperature on each phase winding, a thermal switch should be installed in the stator lead coil, which can be connected to the motor overload protection and the control cabinet.
Suppliers must provide the signal specifications for each protective sensor of the motor to ensure signal transmission.MCC。
The motor's stator winding is equipped with an over-temperature sensor.
Install leakage sensors to prevent liquid from entering the stator windings.
Leak detection devices should be installed in the motor cable junction box.
The rated power of the motor should be greater than the specified shaft power.1.1x
Cable entry sealant:
The cable entry seal design should be capable of eliminating a certain amount of torque to form a waterproof diving seal. The seal should ensure the replacement of the cable and cannot be sealed using epoxy, silicone, or other secondary sealing systems.
Cable joint sections should take measures to prevent air exchange between the internal and external cables due to temperature differences.
Cables should be properly secured in water, and the contractor shall provide securing devices.
4) Guide Rods and Brackets:
The rod should be supported at top, middle, and bottom points, and the bracket design should be based on the mixer's installation location and the actual structural diagram of the pool.
Duwan Environmental QJB1.5/6-260/3-980S Submersible AgitatorMachineThe operation mode is local manual control. Two PLC automatic control methods.
Manual Control
Diving AgitatorMachineEquipped with manual control, operational even when automatic control is not achievable.Achieve manual control. That is: when the control cabinet panel is“Selector switch”Placed in the manual control position, the machineManual execution via on-site control switches is available, with the handle control buttons allowing for separate operation of the equipment's functions.
2. Automatic Control
Please provide the Chinese content you would like translated into American English. PLC Automated Operation Mode, Submersible MixingMachineAutomatically controlled by time. Submersible mixerMachineContinuous or intermittent operation.
When the switch is set to the fully automatic control position, the machine can operate in the following modes.
(1) Through the start button on the control panel.
(2) Time control via the control panel.
Jiangsu Du'an Environmental Protection Quality Inspection System:
Jiangsu Du'an Environmental ProtectionWe have an independent quality inspection agency with the authority to reject quality issues. During the inspection process, inspectors strengthen"Triple Inspection": Conduct inspections strictly according to the "Product Monitoring and Measurement Control Procedure," the "Control Procedure for Monitoring and Measuring Devices," and drawings, as well as various inspection specifications. Strengthen control over non-conforming products according to the "Non-Conforming Product Control Procedure," ensuring that non-conforming products do not flow into the next process. Establish quality control points at critical processes, such as pneumatic testing, rotor and impeller dynamic balancing, and assembly of bearings and mechanical seals, to enhance quality control and ensure stability.
We conduct quality supervision and inspections of product quality, on-site management, and process discipline, and implement a quality accident and loss compensation system. Regularly organize technical training, quality education, and assessments for operators, inspectors, and other personnel to ensure that workers possess adequate technical qualifications and operational abilities while enhancing their quality awareness.
