Failure and elimination method of vertical pipeline centrifugal pump

ISG vertical pipeline centrifugal pump, pipeline pump, also known as centrifugal pump, centrifugal pump, single stage centrifugal pump, vertical pump, booster pump, hot water pump, circulating pump, booster pump, using IS type single-stage single suction centrifugal pump performance parameters, a clever combination is designed based on general vertical the pump, and the use of temperature, medium in different ISG derived on the basis of the application of hot water, high temperature corrosion resistant chemical pump, oil pump. The series of products with high efficiency and energy saving, low noise, reliable performance and other advantages, in line with the latest National Machinery Department JB/T53058-93 standard requirements, the product according to the international ISO2858 standard design and manufacture.

ISG type vertical pipeline centrifugal pump barrier and eliminating method:

1.ISG 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, the pump is mounted on the basis of the application level of the level of the pump and motor shaft inspection apparatus, such as level is adjusted until the level of application of shim, adjusting properly tighten the foot nut,

4 check the pump rotating parts are stuck rubbing, should strictly check the pump shaft and the motor coaxial, can regulate the thin concentric, finally hand rotation coupling, easy rotation even without rubbing is normal.

5 pump suction and discharge pipeline should have their own support, does not allow the weight of the pipeline directly to bear by the pump, so as not to pump down,

The installation position is higher than the water level (6 pump in the pump suction permitted), at the end of suction line should be installed on the bottom and the discharge pipe arranged on the liquid filling hole or valve, for the pump before starting liquid injection; pump installation position below the surface, in the suction pipe on the press install control valve and filter device, to prevent debris into the pump, filter area should be more than 3-4 times 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.
