Second, the assembly and disassembly of a pump, the assembly of the DG pump assembly quality directly affects the quality of the pump can pump DG25-30 * 9 for the normal operation of the pump, and affect the life and performance parameters of the pump; the effects of vibration unit and 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 the quality of the boiler feed pump, should ensure accuracy and surface roughness of the parts are not allowed to touch, scratched. 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, so the pump size can not be adjusted. c, the pump is assembled, is not installed before the filler DG25-30 * 6 boiler feed pump, hand pump rotor rotation, check that the pump rotor rotating inside the casing is flexible, whether to meet the requirements axial movement. 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, where the point of dismantling the pump can be replaced or lubricated. Since one of the most common fault with subsystem failures caused by motor overheating, which is mainly due to the fan is damaged, ventilation channels blocked, bearing wear and other reasons that the ventilation system is not overheated boiler feed pump pump pump heat should check whether the shaft is bent or two shaft misalignment while checking impeller balancing DG6-25 * 7 boiler feed pumps, two-axis adjustment shaft or adjust the concentricity, remove impeller balance holes, in order to ensure a balance shaft and impeller rotation, troubleshooting. DG25-30 * 6 boiler feed pumps, boiler feed pumps, industrial boiler feed pumps provided by Anguo Shi Yuan Pump Company. Anguo Shi Yuan Pump Co., Ltd. (www.shiyuanbeng.com) strong, credible, in Baoding centrifugal pumps and other industry has accumulated a large number of loyal customers.
