stainless steel centrifugal pump elevation adjustment and water at the beginning of pingdu elevation measurement to elevation benchmarks ( Commonly known as zero relative elevation difference ( Positive or negative values of the elevation said here. Elevation points absolute level and relative level. Absolute level is based on sea level ground zero, and the sea level difference, known as the absolute elevation; Relative elevation is when a certain elevation benchmarks as zero, - With the benchmark height difference is called the relative elevation values. Mainly use relative elevation in engineering, and habits in elevation. Centrifugal pump elevation adjustment is in order to facilitate the pump body and the pipe connection, in general, its point of elevation measurement for pump axis t, to pump calibration based on elevation as the measuring datum, the basis of the measured with liquid level connectors, as shown in figure 1. Strict requirement for the pump, and its level is measured with level adjustment. Centrifugal pump elevation deviation should be allowed to meet the provisions of the table 1. Large deviation can be temporary shim to adjust. Initial water pingdu centrifugal pump for water pingdu elevation, after may be looking for can be simultaneously, it is by adjusting the temporary shim to adjust the levelness of high and low. The levelness of the centrifugal pump application accuracy of adjustment. Mm/m level or for accuracy. Mm/m level, in the import and export of the pump or pump shaft is measured on the surface of the flange. Horizontal split casing pump, can keep the level in the level of points on the surface or the pump shaft and import and export is measured on the surface of flange. Centrifugal pump levelness allowable deviation: for installation as a whole. Pump, vertical horizontal deviation should not be greater than. /, lateral horizontal deviation should not be greater than. /; For the collapse of the installation of vertical and horizontal pump horizontal deviation are not greater than. /。 Stainless steel centrifugal pump installation of centrifugal pump location and correction of centrifugal pump in position and alignment, is to add to the pump according to the foundation of the centerline on the basis of adjustment of the pump body vertical, horizontal centerline, make it meet the requirements. In the process of the installation of centrifugal pump, for general middle and small centrifugal pump, its share a stand with motor, are installed through the overall installation method, namely in the above preparation is complete, the pump and motor and stand together smoothly in the whole, and then to find positive and leveling. For large centrifugal pump is usually the first stand hoisting in place and adjust the center position and levelness, then lifting pump and motor to adjust the levelness coupling shaft end frame spacing, etc. YAZE( Pneumatic company's main products: pneumatic pneumatic valve pneumatic ball valve pneumatic butterfly valve Keywords: pneumatic pneumatic valve pneumatic pneumatic valve
