As we all know, the submersible fire pump is used underwater. Relative to the ordinary fire pump, there will naturally be more problems. So, what are the common problems with submersible fire pump?
1, Rust, such as the impeller corrosion;
2, Short life;
3, Easy to block;
4. Disadvantageous for maintenance;
5, The fixing screw is loose, so that the spring loses its effect;
6. The shaft sleeve wear too much;
7, The pressure is insufficient, the pump can not be used normally.
The submersible fire pump is different from the ordinary fire pump, and it will be more serious in many common problems. Among them, the insufficient pressure is a big deal!
So, what is the root cause of insufficient pressure of the submersible fire pump?
1. The pump is not filled with water or is not properly vented;
2, the rotate speed is too low;
3. The system head is too high;
4. The suction head lift is too high;
5. The impeller or pipeline is blocked;
6. There is leakage in the air or inlet pipeline;
7, the direction of rotation is wrong;
8. The bottom valve or inlet pipe is not deep enough;
9. The bottom valve of the fire pump is too small;
10, the packing or seal wear, so that air leaks into the pump casing.
