Abstract
The utility model discloses a water pump, include the endless groove is established in the water pump bottom, the blade is installed to the endless groove top, blade swing joint is around the impeller, impeller fixed connection is outside at the center pin, center pin and rotation axis swivelling joint, the rotor is installed outward to the rotation axis, the rotor closely links to each other with motor stator, rotor and motor stator top are equipped with the engine space, the bearing is installed around the engine space. The utility model discloses water pump, the structure is simple relatively, and reasonable in design can prevent to get into the engine from the water that water pump's pump part was leaked to consequently water pump's reliability can be improved, and when high -speed rotatory impeller, the wearing and tearing of bearing have also dropped to minimumly in addition, the performance that has improved water pump with and life.
Description
Technical field
The utility model relates to pump technical field, is specially a kind of water pump.
Background technique
Existing water pump, although be provided with weep hole, but still some water from pump partial compromise likely accumulates in the inner easy-to-rust part side of pump, what also have may leak to engine section along hermetic unit, causing the engine long time has ponding and damages, the cooling performance of pump neither be fine in addition, easily occurs the problem of the lifetime of pump.
Model utility content
The purpose of this utility model is to provide a kind of water pump, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technological scheme: a kind of water pump, comprising described annular slot is located at bottom water pump, above described annular slot, blade is installed, described blade is movably connected in around impeller, described impeller is fixedly connected on central shaft outside, described central shaft is rotatably connected with running shaft, outside described running shaft, rotor is installed, described rotor is closely connected with motor stator, be provided with between engine air above described rotor and motor stator, described bearing is arranged on motor spatial peripheral.
Preferably, described central shaft is rotary structure.
Preferably, described motor stator is located at rotor inner circumferential side, and described motor stator, rotor, impeller and blade and motor form a driving structure.
Compared with prior art, the beneficial effects of the utility model are: this water pump, structure is relatively simple, reasonable in design, can prevent the water of the pump partial compromise from water pump from entering motor, thus therefore the reliability of water pump can be improved, in addition when high-speed rotating impeller, the wearing and tearing of bearing also drop to minimum, improve water pump performance and its working life.
