Abstract
The utility model discloses a water pump connecting-body concentric shaft device which relates to a device concentrically connected by a water pump body and a motor and is especially suitable for all large-medium power water pumps. The structure of the utility model includes a connecting-body concentric pump shaft, a connecting body, and a bearing; the connecting body is internally provided with a bearing seat; one end of the connecting-body concentric pump shaft is provided with a concentric sleeve or a concentric flange which is connected with the motor shaft; a middle part of the connecting-body concentric pump shaft is provided with the bearing; the other end of the connecting-body concentric pump shaft is connected with a water pump impeller; the bearing device is arranged in the bearing seat of the connecting body. Two sides of the bearing seat are provided with a sealing cover; the bearing seat is internally provided with a lubricant. The bearing seat is internally provided with a water cooling device.
Description
Technical field
What the utility model water pump disjunctor concentric shafts device related to is a kind of pump body and the concentric connection set of motor, is specially adapted to various types of high and medium power water pumps.
Background technique
The high and medium power pump body all is to adopt coupling to be connected with motor at present, and concentricity is poor, and the elastomer block on the coupling is worn and torn easily, influences the normal use of water pump, and maintenance is frequent, dismantles very inconvenient.In addition, because water pump connects with coupling, concentricity is poor, and noise is big during work, influences surrounding environment.
Summary of the invention
The utility model provides a kind of water pump disjunctor concentric shafts device at above-mentioned deficiency, and pump body is connected the concentric pump shaft of employing disjunctor and connects with motor, good concentricity, and long service life, easy to loading and unloading, maintenance rate is low, and noise is little during work, and is free from environmental pollution.
Water pump disjunctor concentric shafts device takes following scheme to realize: water pump disjunctor concentric shafts device comprises the concentric pump shaft of disjunctor, connecting body, bearing, be provided with bearing support in the connecting body, concentric pump shaft one end of disjunctor is provided with concentric locking collar or the concentric flange that is connected with motor shaft, bearing is equipped with at the concentric pump shaft of disjunctor middle part, the other end connects water pump vane, and bearing means is in the bearing support of connecting body.
When water pump disjunctor seat concentric shafts device uses, the concentric pump shaft of disjunctor is loaded onto bearing, be installed in the bearing support of the concentric seat of disjunctor, pump cover is installed on the concentric pump shaft of disjunctor and with connecting body is connected, the Sealing of mechanical seal is installed again, load onto impeller then, the concentric locking collar of the concentric pump shaft the other end of disjunctor directly is connected with motor shaft by axle key, or the concentric flange of the concentric pump shaft the other end of disjunctor directly is connected by axle key, bolt with concentric flange on the motor shaft, and with bolt connecting body is fixed on the motor adpting flange, can normally use.
Water pump disjunctor concentric shafts device is owing to adopt connecting body, the direct-connected electric-motor-driving of the concentric pump shaft of disjunctor, substituted traditional coupling Placement, it is easy to wear to have avoided traditional coupling to connect its elastomer block fully, need the often defective of replacing, guarantee the concentricity that pump shaft is connected with motor, improved pump work stability, thereby reduced the power loss of noise and machinery.Adopt water pump to connect the concentric shafts device, make pump body and motor connecting structure compactness, improved mechanical stability, be convenient to mounting or dismounting, easy to maintenance, alleviate labor intensity of operating personnel greatly.
Description of drawings
The utility model is described in further detail below with reference to accompanying drawing.
Fig. 1 is water pump connecting body concentric shafts apparatus structure and user mode schematic representation.
Embodiment
With reference to accompanying drawing 1, water pump disjunctor concentric shafts device comprises the concentric pump shaft 6 of disjunctor, connecting body 1, bearing 5, be provided with bearing support 4 in the connecting body, concentric pump shaft 6 one ends of disjunctor are provided with concentric locking collar 2 or the concentric flange that is connected with motor shaft 8, and bearing 5 is equipped with at the concentric pump shaft of disjunctor 6 middle parts, the other end connects water pump vane 7, bearing 5 devices are in the bearing support 4 of connecting body 1, and sealing cover 3 is equipped with in bearing support 4 both sides, in the bearing support 4 lubricant oil is housed, and water cooling plant 9 is housed, as the water cooling pipe fitting.
