the stage bulbs ammeter reading may be water supply large amount of friction in the pump. If the ammeter reading is too small, indicating that the pump has been falling into the water or the outside world does not need so much water.the stage bulbs vacuum gauge, pressure gauge, ammeter readings are normal pointer of the vacuum table of the stage bulbs can not swing too much, such as swing likely is the entrance of the vaporization.the stage bulbs another vacuum gauge readings can not be too high, too high may be blockage of the entrance door jammed, or the entrance door flap off, suck pond water level to reduce.ent instrument pressure gauge reading is too low, could be bad inside the pump work, the seal ring and severe wear.the stage bulbs when the water demand of another system, the pump outlet pressure will be reduced.
