Slurry running current is small, if the external load does not change, there may be a faulty water supply system, the pump output is small, then the system should be checked, can see a small pump output may cause.
Current is reduced, if the voltage is too low because the result will cause the pump output shortage, caused by the reduction of water if the outside world, should adjust or adjust the fluid recirculation Even so output matches with water to avoid playing boring pump cause vaporization phenomenon. Slurry current decline means acting decline generally due to drop in traffic caused. Accordingly Find causes traffic decline. Impeller worn or clogged pipes most likely. It could be the pump outlet valve opening is small, or low inlet pressure does not meet the design requirements, there may be an inlet pipe blockage.
Solid and liquid mixed with slurry Slurry transport in recent years due to the larger particles and higher material evolved an efficient and relatively strong performance of centrifugal pumps, CPP is currently one of the various process equipment indispensable. Actual operating point is determined by means of slurry pump slurry pump characteristic curve and the curve of intersection of slurry. Selection and use of slurry pumps, slurry pump manufacturer slurry pump operating point should be made to fall within the scope of work to ensure the functioning of the economy and security. Further, the same slurry viscosity of different liquids during transportation, the characteristic curve also changes.
Typically, the slurry pump characteristic curve given by the manufacturer is the most characteristic curve when transporting clean cold water. Slurry pump for power, with the viscosity of the liquid increases, reduced head and efficiency, shaft power increased, so the industry will sometimes viscosity of the viscous liquid heating smaller to improve transport efficiency.
