Pump Model significance: 2.5GC-6 × 5 2.5- inlet diameter (mm) and is divided value of the whole 25. GC- boiler feed pump. 6- ratio reduced to 0.1 revolutions of the pump, that is, than the number of revolutions of the impeller 605- number or series. [Product Structure]? A bush ... the main structure of the pump inlet, outlet are vertically upward, the rotor axial force to balance the balance disc. Seal for packing, but also for the mechanical seal. Rotor bearing only DG85-80, DG85-67, DG155-67 sliding bearings, lubrication import boiler feed pumps, other pumps are used rolling bearings. 1, the pump casing parts: pump housing part by bearing body, front, middle, rear section, the guide leaves, bolted into the whole front line was horizontal suction mouth, posterior segment vertical and horizontal outlet. 2, the rotor part: some of the major axis of the rotor and impeller mounted, bushings, balance disc and other parts of the shaft components. Parts shaft sleeve nut flat keys and make it with the shaft into one. Entire rotor from both ends of the bearing in the pump housing, number of impeller rotor section is based on the number of stages depending on the pump. 3, bearing parts: The pump bearings have two sliding bearings and rolling bearings, according to the model may be, are not subjected to axial force. Pump in operation should be allowed rotor portion axial swimming in the pump housing, can not be used radial ball bearings 4, pump seal: Pump front, middle section of the sealing surface between the rear are made of molybdenum disulfide grease seal , by sealing ring, the guide vane sets, packing and other sealing, when should the seal ring and vane wear sleeve has affected the work and performance of the pump to be replaced between the rotor portion and the fixed portion. This type of pump is in use, the position of packing rings placed to the right, the distribution of various types of packing and packing ring pumps are shown in Table 2 boiler feed pump starts, the tightness of the filler must be appropriate, in order to be able to drop by drop liquid oozing appropriate . 5, curve explanation: the graph is single stage performance, the nominal diameter of the impeller D2 = 134㎜, speed n = 2950r / min. When the series progression increases in proportion to increase lift, constant flow. For example: three lift lines in the graph line lift Richard multiply by 4 3,4 level, the rest on the boiler feed pump start, boiler feed pumps, DG6-25X3 by Anguo Stone yuan Pump Company.
