shadowless lights 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.shadowless lights vacuum gauge, pressure gauge, ammeter reading is normal
shadowless lights vacuum table pointer does not swing too large, such as swing likely is the entrance of the vaporization. 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.
shadowless lights low pressure gauge readings may be inside the pump working poor sealing ring and severe wear. Pump outlet pressure will reduce the water demand of another system.
