Description
Technical field
The utility model relates to a kind of vortex type water pump, particularly relevant shielding self-priming water pump.
Background technique
The vortex type water pump is widely used in occasions such as water air-conditioning, solar water heater and pressurized water supply.At present, domestic vortex type water pump generally adopts the fan blade cooling, and there is the shortcoming that cooling effect is poor, noise is big in it.Chinese patent literature CN2040187U discloses a kind of self-priming pump mechanical seal internal water cascading mechanism, and it is that the water pump main shaft is axially punched, and water flow to mechanical seal from axis hole, has strengthened cooling, the developing result of sealing.But owing to be subjected to the restriction of water pump main axe intensity, axial bore can not be opened greatly, so the slow deficiency of water cycle has been brought in the hole for a short time, thereby influences cooling effect; After pump operation stops in addition, have a large amount of air in fluid injection case, pump work chamber and the suction sleeve that connected, must vacuumize once more when restarting, it is loaded down with trivial details to work, and efficient is not high.Though Centrifugal water pump can be realized the circulation of cooling water, Centrifugal water pump is compared with the vortex type water pump of same power, has the cost height, inhales the short deficiency of journey and lift.
Summary of the invention
The purpose of this utility model is to provide a kind of and need not vacuumizes once more when restarting, the shielding vortex type self-priming circulating water pump of cooling water automatic cycle cooling motor and motive sealing.
In order to achieve the above object, the technical solution of the utility model is: a kind of shielding vortex type self-priming circulating water pump, comprise motor, peripheral pump and fluid injection case, wherein, motor comprises shell, end cap, stator and rotor, between stator and rotor, has housing, the chamber that rotor body places housing and end cap to constitute; Peripheral pump comprises housing and impeller; The fluid injection case has water intake and water outlet, the inlet end of fluid injection case is equipped with safety check, be connected with circulating pipe on the fluid injection case, circulating pipe communicates with the inner chamber of housing, has circulating water outlet on the end cap, the inner chamber of housing communicates with the blade wheel chamber of peripheral pump by the circulating water outlet on the end cap, be installed in as the motive sealing supporting assembly parts of rotor shaft supporting on the end cap of the housing of peripheral pump or motor, one side of motive sealing supporting assembly parts is communicated with the inner chamber of housing, and the opposite side of motive sealing supporting assembly parts is communicated with the blade wheel chamber of peripheral pump.
After adopting said structure, when quitting work owing to intake first at water intake back or peripheral pump, safety check has cut out the water route automatically, make whole fluid injection case and peripheral pump active chamber be full of water all the time, this need not vacuumize once more with regard to making water outlet at once when restarting, and has realized first automatic absorbent function; When peripheral pump is started working, because the gravity pressure of water is added the circulation that the eddy stress that forms when impeller runs up is promoting water in the fluid injection case, inject cooling water by circulating pipe to the housing inner chamber of motor, also the motive sealing support assembly is carried out the automatic cycle cooling simultaneously, final cooling water, circulates thereby finished second automatic suction to the fluid injection case by circulating water outlet row, promptly the utlity model has two self-absorption functions, and high working efficiency, good cooling results.In addition with the Centrifugal water pump of same power relatively, advantage such as it is big to the utlity model has lift, and the pumpdown time is short.If use with water air-conditioning coupling, can realize both cooling and heating, it is long to have a lift, and it is low to consume energy, and noise is low, and economical and practical characteristics are particularly useful for the use of rural area and north cold area.
