Water hammer occurs, causes and treatment methods are as follows: (1) due to a sudden power outage, causing the system pressure fluctuations appear vacuum exhaust system, dissolved in a liquid pump or air bubbles escaping gas pipeline memory. Approach is the gas drained. (2) high pressure liquid column due to a sudden power outage rapid intrusion, shock at the pump outlet check valve plate. Approach is unreasonable pump exhaust system pipes, pipe fittings layout transformation. (3) the valve outlet pipe closed too quickly. Approach is to slowly close the valve. Adjustment (1) sealing ring with clear water wheel gap small caliber pump flow 150, the entry of foreign economic relations should be turning water wheel or turning the sealing ring through, a large gap should be reconstituted. (2) sets of guide wing inappropriate interval should be replaced or turning impeller gear sets. Onchocerca balance should cover the gap is small turning Onchocerca sets foreign economic balance, a large gap to be reconfigured. (3) the degree of eccentricity is not perpendicular to adjust and balance disc. Avoid pump vibration generated during operation pump, the shaft bending and damaging other parts; the balance disc not vertical multistage horizontal centrifugal pump, during operation will balance disc mill side. (4) need to have a few gaps. Unassembled balance disc shaft string amount of 6.0 ~ 8.0 mm suction water pump is not pumping, assembled late string balance amount of 3.0 ~ 5.0 mm, concentricity error does not exceed the balance disc 0.06 mm, vertical balance disc and shaft error should not exceed 0.05 mm.
