DG horizontal multi-stage boiler feed pump assembly and demolition matters needing attention

DG type horizontal multi-stage boiler feed pump assembly quality is directly related to whether the pump can be normal operation, and affect the pump life and performance parameters, as well as the unit vibration and noise. The following is to introduce the DG horizontal multi-stage boiler feed pump assembly and disassembly should pay attention to the matter as follows: DG horizontal multi-stage boiler feed pump assembly and disassembly should pay attention to matters First, DG horizontal multi-stage Boiler feed pump assembly should pay attention to matters 1, the fixed part of the combination of parts after the concentricity of parts manufacturing accuracy and assembly quality to ensure that the parts should be processed and surface roughness, not allowed to touch, scratch. Molybdenum disulfide used as a sealant should be clean. Tightening screws, bolts should be force evenly. 2, impeller exit runner and guide vane inlet flow channel is dependent on the axial size of the parts to ensure that. The quality of the flow channel has a direct impact on the performance of the pump, so the size of the pump can not be adjusted. 3, After the pump is assembled, before turning on the filler, turn the pump rotor by hand to check whether the pump rotor rotates freely in the housing and whether the axial movement meets the specified requirements. 4, after the inspection meets the requirements, add packing at the shaft seal at both ends of the pump, pay attention to the relative position of the packing ring in the packing room. Second, DG horizontal multi-stage boiler feed pump disassembly should pay attention to the matter 1, disassembly and assembly in reverse order, demolition should be strictly protected parts manufacturing accuracy from damage. 2, the demolition of the wear bar should be the first cushion with the middle pad, so as not to loosen the middle of the stop after the shaft bending.
