Structural Characteristics of Shenyang Dafang Pump VC Series Vertical Condensate Pump

One of the main products belonging to Shenyang Dafang Pump Co., Ltd., the VC series vertical condensate pump can be used to transport condensed water in the condenser hot well in a nuclear power plant under high vacuum , Can also be used in NPSH or installation of the chemical surface of the restricted chemical process physical and chemical properties of the water transport medium. The following is the Shenyang Dafang Pump VC Series Vertical Condensate Pump structural features: Shenyang Dafang Pump VC Series Vertical Condensate Pump structural features (1) Pump Cylinder: Pump cylinder designed by the full vacuum, is a high-quality carbon A circular cylindrical part made of a steel plate or a stainless steel plate is welded with a suction flange on one side. The pump cylinder is used to form the outer pressure chamber of the double-shell pump, which is under negative pressure during normal operation. (2) Working Department: The working department is composed of a pump rotor which is arranged in the same direction with a plurality of impellers and a guide shell which forms a guide space at the periphery thereof. Pump rotor from the impeller, pump shaft, keys, bushings and other components, part of the pump rotor induction wheel. Induction wheel is the role of the first impeller into the liquid before the pressure to avoid cavitation. The shaft serves as both a carrier for the impeller and the entire load on the rotor. Pump shaft and induced wheel, impeller coupling in two forms, one is the key, snap ring connection, key transmission torque, snap ring axial positioning; one is the clamping sleeve connection. Impeller is closed, the first impeller has a single suction, double suction two types. When necessary, design induction wheel. The function of the guide shell is to guide the liquid flowing out of the impeller to the next-stage impeller uniformly with the least loss. The connection between the guide shell is the mouth of the positioning, stud fastening. And diversion shell with replaceable wear ring; wear ring material selection RWA350 (equivalent to 1Cr13MoS), excellent anti-bite ability. Pump has a number of water-lubricated bearings as the intermediate support, to withstand the radial force of the rotor. (3) The rotor axial force is added by the pump itself to balance the device + thrust bearing to bear. The pump rotor shaft connected by a cartridge snap ring coupling, the rotor has a good concentricity; pump and motor flange connection with a rigid coupling. (4) Shaft seal is divided into soft packing seal and mechanical seal. According to the needs of users, Yanzhou Heze Zhaolou comprehensive utilization of power plant project 1 × 300MW unit condensate pump seal with double-ended mechanical seal. (5) water part: water part of the adjustable tube, pipe, spit out of the seat and other components. The pump's countershaft through which the drive shaft passes. From the working part of the pump out of the liquid through the part of the level after entering the pump pressure pipe. Spit out the seat with a sealed letter, pressure relief hole, off the steam hole. The pressure relief hole is used to minimize the pressure in the shaft sealing cavity; the steam releasing hole is used to discharge the gas in the cylinder to the condenser in time. Pump set can be reversed at 10% of rated speed (reverse speed limited by vertical motor). (6) pump steering: From the motor to see the pump is rotated counterclockwise.
