Detailed Description
General
Model QD (G) pump is a horizontal multi-stage centrifugal pump and suitable for transporting pure water (with the contained foreign matters' content less than l % and graininess less than 0. 1mm) and other liquids of both physical and chemical natures similar to those of pure water.QD (G) model middle and low pressure boiler water supply pump is applicable to transport medium with temperature of not higher than 120℃, and is also applicable for small boiler water supply or transporting medium similar to hotwater.QDG model hypo-high-pressure boiler water supply pump is applicable to transport medium with temperature of not higher than 180℃, and is also applicable for small boiler water supply or transporting medium similar to hot water.    Performance range of mode QD (G) series    Flow: 3-684m3/h       Corollary power: 4-3400kW    Head: 15.78-684m      Inlet diameter: 25-450mm
Structure
For this series horizontal multistage centrifugal pump, both ends of it are supported, the casing portion is in a sectional form. it is connected to and actuated by a motor via a resilient clutch and the rotating direction of it. viewing from the actuating end. is clockwise. Refer to Fig. I for the structure of it.
Stator portionConsists of suck-in section. middle-section, spitting section, guide vane, packing etc., which are linked together with a take-up bolt. with both suck-in and spitting mouths vertically upward.
Rotor portionConsists of a shaft, impeller, balancing disk, muff etc. Parts.
Bearing portionThe whole rotor is supported by the roller bearings orsliding bearings on both ends of the shaft and the bearings are lubricated with grease or 20# engin oil.
Cooling and seal of pumpThe joint-part between suction section, intermediatesection and discharge section with be coated with molybdenum disulfide lubricating grease as seal. Rotor and fixed parts will be sealed by seal ring, guide-vane jacket and packing. The packing tensile degree of shaft seal should be proper and seep should be feasible dip by dip Unload run should be forbid. The seal ring and guide vane jacket should be replaced if they are too worn to be used any more and even do harm to pump work. There is spare shaft sleeve near shaft seal to protect shaft of pump.
