Underground pumping explosion proof sewage pump is also a life, as with people will experience a life, old, sick, dead process, but it is another way of saying it, the sick refers to the failure. If something goes wrong, we will have to deal with it promptly. At this moment, if we know how to analyze the cause of the malfunction and find the corresponding method to solve the problem, we can save a lot of trouble for us. Fault phenomenon: insufficient or no flow of water Analysis: 1. Impeller rotation error 2. Valve is open and intact 3. Pipe impeller is blocked 4. Low speed 5. Lift high 6. Pumping medium density 7. Medium viscosity High 8. Seal damage (mouth ring Department) to lift the method: 1. Adjust the impeller rotation 2. Inspection, maintenance and removal 3. Cleaning debris 4. Check the electrical equipment and circuits 5. Change the pump or reduce the head 6. Reduce the concentration of water dilute 7. Reduce the viscosity 8. Failure phenomenon: unstable operation Cause analysis: 1. Impeller imbalance 2. Bearing damage to the lifting method: 1. To send the factory exchange or correction 2. Replacement failure phenomenon: the pump can not start Cause analysis: 1. Missing phase 2. Impeller stuck 3. Winding, joint or cable break 4. Stator winding burnout 5. Electrical control failure to remove: 1. Check the line for repair 2. Remove debris 3. Use Ohm inspection and repair 4. Repair, replace the winding 5. Repair or replacement Fault phenomenon: excessive current Cause analysis: 1. Low working voltage 2. Pipeline, impeller is blocked 3. The pumping liquid height or viscosity 4. Use Lifting too low lift method: 1. Adjust the working voltage 2. 淸 management Road, impeller blockage 3. To change the density or viscosity 4. To reduce the flow. Raise the head of the fault phenomenon: Insulation low power group analysis: 1. Tuen cable power terminal leakage 2. Cable damage 3. Mechanical seal wear and tear caused by leakage 4. Each 0-ring failure 5. A case of corrosion by the medium leakage Leakage method: 1. Tighten the compaction 嫘 mother 2. Repair These are the underground explosion-proof sewage pump common failure and its lifting method, if you have a serious look Once again, I believe if you encounter similar problems in the follow-up daily life, you can deal with them on their own without resorting to asking for help.
