ISG type single stage single suction vertical centrifugal pump barrier and elimination method:
1. ISG type vertical pipeline centrifugal pump installation is reasonable, the normal operation and service life of the pump has a very important influence, so the installation and correction must be carefully carried out.
2. Control installation size embedded anchor bolt, make concrete foundation work.
3. To be the basis of cement solidification after the pump is mounted on the basis, level of application level instrument to check the pump and motor shaft, such as level, application of adjusting pad iron is until levels and adjusted properly after tightening the foot nut.
4. Check the pump rotating parts is stuck in a collision phenomenon, should strictly check the pump shaft and motor coaxial degree and flakes available adjustment the concentric, finally hand rotation coupling, rotating easily even without brush touch phenomenon is normal.
5. The pump inhalation and spit out the line due to the respective support, does not allow the weight of the pipeline directly by the pump to bear, so as not to pump crushed,
6. The pump installation position above the liquid level in the pump suction within the allowable range) should be on the suction pipe end part is installed on the end of the valve and in the discharge pipeline set irrigation liquid hole or valve, pump for filling liquid before starting; pump installation position below the surface should be in the suction pipe installed by the control valve and filter device, to prevent debris into the pump, filter area should be 3-4 times larger than the area of the pipeline.
7. High lift pump in the outlet flow control valve on the outer end of the pipeline should also be installed check valve to prevent sudden stop when the water hammer damage.
8. Must ensure that the pump installation height is in line with the pump cavitation margin, and consider the pipeline loss and medium temperature.
