Within TDY type pump adopts horizontal double shell, shell for sectional multistage centrifugal pump, but without mobile line for repair. Available for flow of oil products not containing solid particles, oil chemical process pump and other chemical industrial products.

TD type pump is horizontal double hull, for sectional multistage centrifugal pump, the shell can be without mobile line inside the shell can be taken out for repairs. Suction and discharge pipe are vertical layout, the center line of the horizontal support. Pump is mainly composed of pump barrel, pump cover, and the suction section, middle, guide vane, shaft, impeller, cooling Chambers, the balance disc, such as balanced set of parts. Impeller on the shaft installed in the pump rotor, balance disc and other parts. Order hot loaded on the shaft, impeller pump at both ends of the composed of forced lubrication radial bearing and thrust bearing, thrust bearing for twoway oil controlled circulation lubrication, respectively is equipped with temperature protection and monitoring instrument. By the axial force balance device to balance, the remaining axial force and the additional axial force produced under special condition shall be borne by thrust bearing.Pump shaft seal for the mechanical seal, the heat generated by the friction pay by forced circulation liquid away. Set up by circulating fluid through the cooler and filter, guarantee the circulation fluid cleaning.

Low speed, driven by a prime mover directly through diaphragm coupling. High speed, the pump through the diaphragm coupling And growth through gear box, and then through the diaphragm coupling driven by a prime mover. Look from the transmission direction of pump is clockwise.
