Because of the fault of centrifugal pump pipeline

1, the pipeline centrifugal pump outlet pressure and pumping speed is slow. This phenomenon generally have the following situations:
   The pipeline centrifugal pump air pressure decreases. First look at the pressure of inlet pressure gauge, pressure in the 4 ~ 7 kg as normal. Then check the gas valve opening position, such as the gas source switching is electromagnetic valve, check valve plastic valve is damaged, resulting in plastic valve plates can not be completely open.
   The muffler in exhaust gas pipeline centrifugal pump blocked, can quickly lead to slow down the speed of pump.
   The compressed air pipeline centrifugal pump water or excessive impurities. Enter the diaphragm pump valve after plugging into holes, or stuck valve spool.
   The valve cover is on time by the impact of the spool valve cover damage caused by.
   The pump shaft is inside the four ring wear and leakage.
2, traffic is reduced. This phenomenon generally have the following conditions,
   Import and export of one-way valve of pipeline centrifugal pump (plastic ball) wear small. Or strips, plastic ball particles stuck. Cause when discharging liquid suction outlet recharge, discharge and the material from the feed inlet pressure. The pipeline centrifugal pump diaphragm often lead to tensile deformation, the material volume becomes smaller.
   The black, the layer thickness of diaphragm damage. Axis drive when not in place.
3, the pipeline centrifugal pump does not move. This phenomenon can be several things.
   Spool serious wear and tear on the death card.
   The central axis of the bushing wear. At this point should be to replace the sheath.
   The opposite ends of the central axis screw drop.
   The two layer diaphragm rupture.
   The diaphragm pump upside down or flat. The valve is not return (the first and second generation)
4, the material inside the impurities or oil. This is usually caused by rupture of diaphragm.
5, the import and export of leakage.
   A fastening screw is not damaged, two seat deformation or O type ring, two ends of the pump shell three is not on the hole position and tilt, resulting in two outlet or inlet is not in the same plane.
