Floating submersible aerator FQB5.5 for urban moat sewage treatment
Urban moat sewage treatmentfloat typeDiving aerator FQB5.5Technical Requirements
The submersible centrifugal aerator consists of a submersible motor, an intake pipe, a mixing chamber, and an aeration disc.
The submersible centrifugal aerator can operate normally within the specified range without cavitation, with a running noise of less than 70 decibels and smooth operation. The motor has sufficient rated power.
All pressure bearing parts of the submersible centrifugal aerator shall undergo a pressure test, with a test pressure of twice its design pressure but not less than 0.2Mpa, for a period of 5 minutes without any leakage.
After assembly, the submersible centrifugal aerator underwent a 0.2Mpa air pressure test for 5 minutes without any leakage.
5. The submersible centrifugal aerator is sprayed with epoxy resin anti-corrosion paint, with a coating thickness greater than 300 μ m, and its surface is bright without sand holes, cracks, etc. The overcurrent components are sprayed with epoxy resin anti-corrosion paint.
6. Dynamic balance test of submersible centrifugal aerator wheels and rotors, with a balance accuracy of G6.3 level.
The stainless steel nameplate is firmly fixed in a prominent position on each submersible centrifugal aerator, and the nameplate is marked with stamped numbers.
The lifting ears of each submersible centrifugal aerator are securely and reliably placed near the center of gravity of the aerator cover.
The company mainly supplies manufacturers of submersible mixersThe price of submersible mixers, manufacturers of submersible aerators, prices of submersible aerators, manufacturers of submersible thrusters, prices of submersible thrusters, and other products are of high quality and meet the professional requirements of customers! Manufacturers or individuals in need can call for consultation!
Urban moat sewage treatmentfloat typeSubmersible aerator FQB5Troubleshooting methods
|
Fault phenomenon |
reason |
Clearing method |
|
Power equipment overload |
1. The inlet water tank does not meet the requirements The blades of the submersible aerator are surrounded by debris Friction occurs between the blades and guide vanes of a submersible aerator The speed of the submersible aerator exceeds the specified value |
1. Improve water inlet conditions 2. Remove debris and clean with water 3. Check the wear of the blades and readjust the installation Adjust the prime mover to meet the rated speed |
|
Decreased aeration or no aeration |
The diving depth of the water aerator is too deep Wear of the outer circle of the impeller blades or partial damage of the blades The diving aeration direction is wrong The impeller is loose 5 submersible aerators are clogged with impurities |
1. Improve the submersible aerator 2. Replace the impeller 3. Correct the rotation direction 4 fastening screws 5. Remove debris and use water to clean up |
|
There is noise or vibration during operation |
The foundation of the submersible aerator is not firm enough or the nuts are loose Friction occurs between the impeller and guide vanes 3. Loose impeller screws or damaged blade parts 4. Unstable water inflow state 5 submersible aerators are clogged with impurities |
1. Strengthen the foundation and tighten the screws 2. Check the clearance between the impeller and guide vanes 3. Tighten the screws or replace the impeller 4. Adjust the water inlet status 5. Remove debris and clean with water |
|
The submersible aerator cannot be started or the fuse is blown |
1. Winding, connector or cable open circuit 2. The submersible aerator is blocked 3. Leakage or water leakage 4 Short circuit |
1. Check with an ohmmeter Cut off the power and remove debris 3. Check the insulation, if it is below the specified value, it must be dried 4. Use after inspection and maintenance |
|
After starting the submersible aerator, the circuit breaker and overload device are disconnected |
1. Low voltage 2. High voltage 3. Incorrect motor wiring or confused connectors 4 Control cabinet electrical malfunction |
1. If not in use temporarily or if the voltage drops due to a long circuit, the power cord should be thickened Install two transformers and adjust the voltage to the specified value 3. Adjust wiring and connectors 4. Check and replace electrical components |
