[Sewage Network News] Sewage pumps in the sewage treatment is huge, it can handle acidic or alkaline substances, this advantage makes its use limitations are relatively small. At the same time it is also a kind of installation is simple, very easy to operate the device, its use by many users like it, but it occasionally naughty will, in practical applications, it will fail. Next, a detailed analysis of sewage pump failure analysis and solutions. Sewage pump failure analysis and solutions 1, failure analysis: sewage pump water solution: sewage pump import and export valves are not open, out of the pipeline obstruction, abortion impeller blockage. Solution, remove obstruction. Motor running in the wrong direction, the motor phase loss is very slow: adjust the motor direction, sturdy motor wiring. Suction tube leakage: tighten the sealing surface, remove the air. Pump is not filled with liquid, air pump cavity: Open the pump cover or open the exhaust valve, drain the air. Inadequate supply and discharge of imports and exports, suction stroke is too high, leakage at the end of the valve: downtime inspection, adjustment (water pipe and pipelines with suction easy to use this phenomenon). Pipeline resistance is too large, improper selection of centrifugal pumps: reduce pipe corners, re-select the pump. 2, Failure Analysis: Insufficient sewage pump solution: sewage pump inlet and outlet valves are not open, out of the pipeline obstruction, abortion impeller blockage. Solution, remove obstruction. Partially obstructed impeller, scale deposition, insufficient valve opening: Remove obstruction and readjust valve opening. Centrifugal pump voltage is low: regulator. Impeller wear: replace the impeller. Over-rated flow use: adjust the flow off small outlet valve. Centrifugal pump suction is too high: lower suction stroke. Pump bearing wear: replace the bearing. 3, Failure Analysis: sewage pump noise vibration solution: sewage pump pipe support instability: a solid pipeline. Liquid mixed with gas: improve suction pressure exhaust. Produce cavitation: reduce the degree of vacuum. Bearing damage: replace the bearing. Motor overload heating operation: adjust the flow off the small outlet valve. 4, Failure Analysis: sewage pump motor heat solution: sewage pump flow is too large, overload operation: off small exit. Sewage pump no water, sewage pump flow, sewage pump noise vibration, sewage pump motor heat These conditions are the sewage pump is relatively long in the failure, after years of summary and gossip, we have a very good solution Countermeasures. With the continuous improvement of sewage pumps and progress, I believe in the future, these products will be more suitable for the actual production and use.
