Failure causes: 1, pump enough water; 2, pipe or instrument leaks.
Troubleshooting methods: 1, continue to pump water. 2, tighten the blockage leak.
Common Faults (B): Pump does not absorb water, the vacuum gauge shows a high degree of vacuum.
Failure causes: 1, the end of the valve did not open or blocked; 2, the resistance of the suction pipe is too large; 3 absorbent height is too high.
Troubleshooting methods; 1, correction or replacement of the bottom valve; 2, cleaning or replacement of suction pipes; 3, to reduce the water absorption height;
Common faults (C): Pump no water, pressure gauge shows pressure.
Fault causes: 1, the outlet pipe resistance is too large; 2, the rotation direction is not correct; 3, night traffic jam; 4, speed is not enough.
Troubleshooting methods: 1, reduce or shorten the water outlet pipe; 2, to correct the direction of motor rotation; 3, impeller cleaning; 4, increase speed.
Common faults (d): insufficient flow or too low head.
Fault causes: 1, the impeller or inlet and outlet pipes blocked; 2, double suction seal ring wear too much, or impeller damage, 3, the speed is lower than the specified value.
Troubleshooting methods: 1 clean the impeller or pipe; 2, replace the damaged parts; 3 adjusted to the rated speed.
Common faults (a): pump is not absorbent, pressure gauge and vacuum gauge pointer violently beating.
