DGP self-balancing horizontal multi-stage boiler feed pump for the single-stage multi-suction structure, the suction inlet in the vertical direction for the water inlet, outlet vertical upward in the water section, with a tightening bolt to the pump The water section, the middle, the water section, the secondary water into one, the level of head can increase or decrease the pump to achieve. So how is it structured? Then introduce you to the structure of DGP self-balancing horizontal multi-stage boiler feed pump. DGP self-balancing horizontal multi-stage boiler feed pump structure description 1, the pump's main components: the water section, the middle section, the water section, the secondary water section is the guide vane, anti-guide vane, is the impeller, anti-impeller, shaft , Throttling, decompression device, sleeve, bearing body, transition tube, etc .; 2, the rotor is mounted on the shaft by the impeller, throttling decompression device, anti-impeller, bushings, bearing sleeve and other components; bearings The use of "solid - swim" dry oil lubrication structure, the drive end cylindrical roller bearings, angular contact ball bearings at the end; 3, the pump studio by the water section, the middle section, the water section, the secondary water section, is Guide vanes, anti-guide vanes, transition tubes and other components; 4, the pump inlet section, the middle section, the sealing surface between the water section are sealed with sealant or "O" ring seal, rotor and fixed parts installed between Seal ring. Guide vane sets and other seals, when the seal ring and guide vane sets have affected the wear and tear of the performance of the pump should be replaced in time; 5, shaft seal in the form of mechanical seal box packing seal two. Pump packing used to seal the location of the filler ring placed correctly, the degree of tightness of the filler must be appropriate to the liquid can be a drop of ooze appropriate. Pump seals installed in a variety of sealed chamber, the cavity must pass a certain pressure of water, water seal, water cooling or water lubrication. In the shaft seal is equipped with a replaceable sleeve to protect the shaft; 6, the series of pumps through the flexible coupling or hydraulic coupler directly driven by the prime mover. From the original motive direction, the pump rotates clockwise.
