We have learned that submersible mixers in sewage treatment equipment have strong flow pushing ability, comprehensive leakage protection function, excellent dynamic and static sealing quality, small size, light weight, and long service life. It is mainly used in anaerobic tanks, anoxic tanks, regulating tanks, selection tanks, and sludge tanks of sewage treatment plants.
Regular maintenance and upkeep of the submersible mixer is crucial after it is put into operation
● Change lubricating oil: Submersible mixers usually need to change lubricating oil every six months, using 32 # mechanical oil. When replacing, please carefully unscrew the oil plug, drain the old oil, and be aware that there may be residual pressure to prevent oil spraying.
Installation and disassembly of mechanical seals for submersible mixers: Install under clean environmental conditions and use pure lubricating oil as the assembly medium. First, clean all parts of the mechanical seal, and then smoothly press the static ring device of the submersible mixer seal into the positioning hole, paying attention to protecting the sealing surface of the static ring and avoiding damage to the sealing surface. Then use the guide sleeve to install the dynamic ring onto the shaft, close the oil chamber end cover, and be careful not to collide with the sealing surface of the mechanical seal. When disassembling, follow the reverse order of the above.
● Bearing grease: It is usually replaced once during major repairs, with a grease amount of 1/3-1/2 of the bearing cavity clearance. Recommend using high-temperature calcium sodium based grease.
Leakage protection treatment of submersible mixer: If the leakage protection switch is triggered, it indicates that the mechanical seal on the motor side is damaged and needs to be inspected and repaired. Open the blockage in the oil chamber and drain the accumulated fluid inside.
When using a submersible mixer, attention should be paid to the above issues to maximize its performance and improve sewage treatment efficiency. The suction chamber is located in front of the inlet of the impeller, guiding the liquid to flow towards the impeller; There are three main forms of pressurized water chambers: spiral pressurized water chambers, guide vanes, and space guide vanes; The impeller is the core working component of the pump, consisting of a cover plate and a middle blade.
Before starting the submersible mixer, it is necessary to fill the pump with liquid and then start the centrifugal pump. The impeller rotates rapidly, and its blades drive the liquid to rotate. During the rotation of the liquid, due to inertia, the liquid flows towards the outer edge of the impeller, while the impeller of the submersible mixer sucks in the liquid from the suction chamber. During this process, the liquid inside the impeller flows along the blades. During the flow process, the liquid exerts lift on the blades, and in turn, the blades exert an equal and opposite force on the liquid, doing work on the liquid and allowing it to gain energy and flow out of the impeller. At this point, both the kinetic energy and pressure energy of the liquid have increased.
By paying attention to these issues and performing proper maintenance and upkeep, submersible mixers can play their role and improve sewage treatment efficiency. During the sewage treatment process, submersible mixers play a crucial role in ensuring the normal operation of the sewage treatment system. Timely inspection and maintenance of submersible mixers can extend their lifespan and ensure that they are always in good working condition.
