How to deal with the problem of no water coming out of the stainless steel sewage pump?
Posted by Admin | 07 Jan
Stainless steel sewage pump is a kind of centrifugal impurity pump, which can transport acidic, alkaline or other corrosive sewage. It is widely used in chemical, petroleum, light industry, food, pharmaceutical, brewing, environmental protection and sewage treatment industries. So what should I do if the stainless steel sewage pump does not produce water after it is started?
First, we need to determine the cause of the failure, and then eliminate the problem based on the cause of the failure The motor cannot be started, the pipeline is blocked, the pipeline is broken, the water filter is blocked, the suction port is exposed, the motor is reversed, the pump casing sealing ring, the impeller is damaged, the lift exceeds the rated value of the stainless steel sewage pump lift too much, the impeller reverses, etc. .
1. The flow-through parts such as the water filter, water pipe, diversion shell and other parts are seriously blocked or the water pipe is broken. At this time, the reading of the ammeter often increases and the pointer swings violently. Stop the machine immediately for inspection and cleaning, eliminate circuit faults, remove blockages, repair welding or pipe replacement, and reinstall;
2. The motor runs normally but the water output is small. The reason is that the pump configuration is unreasonable, and the actual head exceeds the rated head of the pump too much, and a higher head pump needs to be replaced. It is also possible that the water pump is reversed. Just change the position of the power cord and adjust any two of the lead wires. If the seal ring or impeller is excessively worn, replace with new parts in time, or replace the high-head pump, and reinstall
3. The motor runs normally but does not produce water. The main reason is that the dynamic water level drops too much during the pumping process. The valve of the water pipe can be adjusted down or the pump can be placed half a meter below the dynamic water surface.
