Common Faults and Elimination Methods of Stainless Steel Self - suction Sewage Pumps
Stainless steel self-priming sewage pump has the advantages of strong sewage discharge capacity, high efficiency and energy saving, good self-priming performance, etc., so what are the common faults of stainless steel self-priming sewage pump and what should be done in case of failure? Exclusion? With these questions, then give you a brief description of stainless steel self-priming sewage pump troubleshooting and troubleshooting. Stainless steel self-priming sewage pump common failure and troubleshooting First, the self-priming pump does not water (a) reasons 1. Pump body without liquid or liquid storage less than 2. suction pipe leakage 3. voltage is too low 4. suction is too high Or suction pipe is too long 5. Mechanical seal leakage is too large (two) the exclusion method 1. Add enough storage solution 2. To eliminate pipe leakage phenomenon 3. Adjust the voltage 4. Reduce suction or shorten the pipeline 5. Repair or replacement Second, the sewage pump insufficient water (a) reasons 1. due to improper use, impeller runner or suction line is blocked 2. Impeller wear and tear 3. Insufficient power speed is too low (two) the exclusion method 1. Eliminate the blockage 2. Replacement Impeller 3. Tune è¥ to rated speed Three, pump 矂 sound, vibration is too large (a) reasons 1. Feet unstable, 2. bearing wear and tear 3. Pump and motor shaft is not coaxial (b) Exclusion Foot 2. Replace the bearing 3. Adjust the coaxiality Fourth, the bearing temperature is too high (a) the reasons 1. Grease deterioration or dry 2. Bearing damage (b) the exclusion method 1. Change the grease 2. Replacement bearings Pump Leakage (A) Reason 1. Loosen the bolt loose 2. Seal mill frequency (two) to exclude 1. Fastening bolts 2. Replace the seal above is stainless steel from Suction sewage pump common faults and troubleshooting methods, I hope the above content can be useful in practical pump which help.
