Equipment commonly known as
Centrifugal submersible aerator, aerator, submerged jet aerator, aerator, self suction submersible centrifugal submersible aerator, aerator, aeration, QXB submersible DSA series submersible centrifugal submersible aerator, aerator, diving push flow flowing aeration machine aerator, aerator, aeration sewage treatment machine, jet aerator the surface aerator,
Brand introduction
The submersible centrifugal aeration machine is suitable for the round pond, with a wide range of aeration and large service area! Centrifugal submersible aerator is a special aeration equipment for water pretreatment and wastewater treatment process, aeration for settling basin, pre aeration tank, the oxidation pond aeration and stirring; also can be used for breeding pond aeration and landscape water conservation; can also be used to process some tap water to remove iron and manganese in the process, can also be used for tap water the water cycle process in high-rise building. QXB type submersible centrifugal aerator, aeration tank for biochemical treatment of various wastewater treatment engineering technology of aerated grit chamber, pre aeration tank and aerobic nitrification tank aeration pond aeration and mixing.
purpose
QXB type centrifugal submersible aerator aeration tank for sewage treatment plant and aerated grit tank mixture of sewage sludge oxygenating and mixing, and biochemical treatment or pond aeration of sewage.
principle
QXB type centrifugal submersible aeration machine for direct connection structure. The rotation of the impeller of a centrifugal force generated in the water, a negative pressure zone is formed around the impeller by centrifugal force, air is sucked through the air inlet pipe, air and water in the mixing tray mixed mixture evenly then this good automatically ejected from the outlet around.
This process includes the following aspects: mixing the air mixed with water generated after gas-liquid mixing effect, gas-liquid mixture outlet form circulation and convection; oxygen molecules in the high-speed movement of a large amount of air to obtain a high oxygen absorption efficiency.
Product features
1 the higher oxygen dissolution rate, the ratio of tiny bubbles, the high filling efficiency and the wide oxygen filling area;
2 no dead zone in the pool, the level of air bubbles can be completely washed by the level of the bottom of each corner of the pool;
3 sets of simple and compact structure, long service life, the bearing can withstand heavy load, the shaft seal and oil bath air suction impeller cavity to prevent water when in contact with the seal, which ensure aeration machine in 24 hours of continuous work, long trouble free operation;

Transportation and usage notes
Never allow for cable suspension or lifting aerator aeration machine. In the chain hook handling or suspension aeration machine can hook on the handle or cover rings.
If the submersible centrifugal machine is still in use or immersed in water, the temperature below 0 degrees Celsius, you can continue to use.
The use of grease or lubricating oil for submersible centrifugal aeration machine. Because the seal wear, oil or lubricating oil leakage. At this time, please hurry up the aerator sent to the factory maintenance department or authorized repair, replace the seal, so as not to burn out the motor.
When the power is not cut off, do not move the aeration machine, people may not enter the water.
After installation of submersible centrifugal aeration machine, can not be long-term immersion in water, it is recommended to run at least 4 hours per half month to check its function and adaptability, or to mention on the dry standby.
The submerged aerator in sewage can not be placed at the entrance, when the chassis is put in the mud or sand, diving aerator vibration generated due to subsidence, in this case, suggestions will be suspended or aerator on a large plate.
Submersible centrifugal aeration machine as a result of working principle, maximum immersion depth should not exceed 3 meters.
Submersible centrifugal aeration machine must ensure safe grounding.
Instructions
Before starting the submersible centrifugal aeration machine, the system shall be examined by a qualified electrician to ensure that the electrical protection measures as required by the following are taken.
Diving aeration machine before running, the application of 0 - 500V million euro to check the motor stator winding insulation resistance, the minimum shall not be less than 1.
The scope of supply voltage must be marked on the nameplate of the rated voltage of the power supply voltage of + 5%, higher value not allowed to exceed the rated voltage of 10%, if the power supply from the submerged aerator using local distance, the cross-sectional area of the cable should be bold, joints should be as less as possible, otherwise it will cause the voltage drop too much and, the joint should be sealed and waterproof.
Four core cable, with their ground, usually yellow line, to ensure safety, must be ground and grow out of prison than other 50mm.
Check the direction of rotation of the impeller
The use of three-phase power supply submersible centrifugal aeration machine, in the first start or after the first time to re install the submersible pump rotation direction, moving direction is not correct, it will reduce efficiency, and damage to the pump.
Inspection methods, submersible aerator in the final before installation, should give high and simple start, looks up from the bottom water submersible aerator and impeller counterclockwise. If a few diving aeration machines are connected to a controller, each of the submerged aeration machines must be examined separately. If the rotation direction is not correct, the position of any two lines in the three-phase line can be switched, and the direction of rotation can be changed.
