Causes of large amount of water leakage at overflow port of pipeline cleaning machine

The causes of a large amount of water leakage at the overflow port of the pipeline cleaning machine are as follows:

If the nozzle selection of pipeline cleaning machine is too small, if the nozzle flow does not match with the pump flow and speed, serious periodic pressure change will occur or the set pressure cannot be reached. If the inlet valve is not closed tightly, high pressure water will leak into the low pressure system (water supply system). Check whether the high pressure water outlet flow is reduced and whether the pressure is reduced

The nozzle of pipeline cleaning machine will be worn, cracked and blocked, and the flow and pressure changes will also occur. However, the valve ports of valve body and valve seat of water supply hose and high-pressure water pipe that will not vibrate will be damaged and cannot be closed tightly. A large number of overflow ports will leak, the flow of high-pressure water outlet will be reduced, and the pressure will drop. If the drain valve is not closed seriously, the high-pressure water will leak between several filling boxes, and the high-pressure water will be discharged The water outlet flow decreases and the pressure decreases.

When the control valve seal of pipeline cleaning machine fails, the seal ring is blocked between the valve body and the valve body by the residue of extrusion and tearing, the movement of the valve body is blocked, the position is incorrect, the outlet pressure changes irregularly, the overflow port leaks a lot, the high-pressure water outlet flow reduces, the pressure drops, and the abnormal noise in the control valve is also reduced

The above is the pipeline cleaning opportunity brought by Xiaobian, and the reason for a large amount of leakage at the overflow port.
