Second, the assembly and disassembly of a pump, the assembly of the DG pump assembly quality is good or bad pump can pump directly affect the normal operation of DG25-30X7 boiler feed pumps, and affect the life and performance parameters of the pump; and a vibration unit noise, the assembly should note the following: a, concentricity of the fixed portion of each part by the combined precision parts manufacturing and assembly to ensure quality, should ensure accuracy and surface roughness of the parts are not allowed to touch, scratch. Molybdenum disulfide as a sealant used should be clean. Fastening screws, bolts should force uniform. b, the exit channel impeller vanes and the inlet passage is to rely on neutral axial dimensions of the parts to be guaranteed. Neutral runner directly affects the performance of the pump DG25-30X4 boiler feed pumps, pump size and therefore can not be adjusted. c, the pump is assembled, is not installed before the filler DG25-30X5 boiler feed pump, hand pump rotor rotation, check that the pump rotor rotation is flexible boiler feed pumps, axial movement whether meet the requirements within the housing. d, after compliance with the requirements of the inspection, the pump shaft seal both ends of adding filler, filler note the relative position of the ring in the packing room. 2.
