Pump accessories structure features introduced

Jun 21, 2018

The pump is a device used in industrial production, which contains many parts and pump accessories. The main parts of the pump are: pump body, pump cover, impeller, shaft, double suction seal ring, shaft sleeve and so on. Except that the shaft material is high-quality carbon steel, the rest of the main parts are usually made of cast iron, cast steel, stainless steel, and other materials.


Under normal circumstances, in the pump body structure, the pump body and the pump cover together form an impeller working chamber. On the access flange of the pump fitting, there is a tube screw hole for installing the vacuum gauge and pressure gauge. The lower part of the inlet and outlet flanges is equipped with a tapped hole for the water discharge. The static balance test impeller is fixed on the shaft with the sleeve and the bushing nuts on both sides, and its axial position can be adjusted by the sleeve nut.


During the operation of the pump, the axial force of the impeller of the pump fitting is distributed symmetrically by means of its blades so that the influent water is balanced on both sides. The pump bearings are radial ball bearings. The bearings are mounted in the bearing body, installed at both ends of the pump body, and lubricated with butter. If an abnormal sound is found during the operation of the pump, stop immediately and check the cause and take appropriate measures to eliminate it.http://www.dmgcastings.com/
