Description
Technical field
The present invention relates to self-suction injection pump, particularly relate to the anti-air refluence formula air guide sleeve of self-suction injection pump, belong to the water pump field.
Background technique
Self-suction injection pump is by the driven by motor impeller, and impeller outer has air guide sleeve, and air guide sleeve is installed in the pump housing; After the driven by motor wheel rotation, produce high pressure, the air in pump and the pipeline, liquid are through in water intake and the flaring jet pipe intake impeller; Get back to the water outlet of the pump housing again through the guiding gutter in the air guide sleeve; Flow in order to help the smooth and easy of guiding gutter, at the opening of guiding gutter air guide sleeve is shaped on the runner mouth, gas, liquid flow to the water outlet of pump through the runner mouth of air guide sleeve.In an air guide sleeve, be generally 5 guiding gutters; Corresponding runner mouth also is 5; And water outlet (top helps air and discharges) on the wall of the pump housing often has place's runner mouth facing to pump housing water outlet, though the rotation of impeller makes gas, liquid flow toward the direction all the time; But when real work; Air refluence (pouring in down a chimney) phenomenon can appear in the guiding gutter of pump housing water outlet one side, can the gas suck-back outside the pump housing water outlet to impeller, so seriously influence the self-priming effect of self-suction injection pump.
Summary of the invention
The objective of the invention is in order to overcome the shortcoming of prior art, provide a kind of and prevent that the pump housing water outlet from producing gas and flowing backwards, improve the anti-air refluence formula air guide sleeve of the self-suction injection pump of self-suction injection pump self-priming effect.
The technological scheme of the anti-air refluence formula air guide sleeve of self-suction injection pump of the present invention is: comprise motor, the pump housing, impeller, air guide sleeve and tubaeform jet pipe, the end cap of motor connects the pump housing, motor shaft impeller; Impeller outer has air guide sleeve, is linked to each other by tubaeform jet pipe between the pump chamber in air guide sleeve and the pump housing, and the pump housing is shaped on water intake and water outlet; Water intake connects intake pipe; Water outlet connects outlet pipe, and air guide sleeve is shaped on guiding gutter, is shaped on the runner mouth in the guiding gutter outlet port; Described guiding gutter is 5; Corresponding runner mouth is 5, it is characterized in that wherein a guiding gutter or a runner mouth are shaped on anti-air refluence catch, and the guiding gutter or the runner mouth that are shaped on anti-air refluence catch are corresponding with the water outlet of the pump housing.
The anti-air refluence formula air guide sleeve of self-suction injection pump of the present invention, starting electrical machinery is after the motor shaft impeller is rotated; Produce high pressure; Air in pump and the pipeline, liquid be through in water intake and the flaring jet pipe intake impeller, and (the gas that comes out from guiding gutter, the pump chamber that liquid arrives first the pump housing, the water outlet that flows to the pump housing is again discharged to get back to the water outlet of the pump housing through the guiding gutter in the air guide sleeve again; So water outlet is built in the top of the pump housing), discharge from outlet pipe.The major character of present technique scheme is that guiding gutter or a runner mouth are shaped on anti-air refluence catch therein; Be shaped on the guiding gutter of anti-air refluence catch or the water outlet that the runner mouth faces toward the pump housing; That is to say at the corresponding guiding gutter of pump housing water outlet (top) or a runner mouth and block by anti-air refluence catch; The gas that prevents pump housing water outlet effectively flows backward in the impeller, improves the self-priming effect of self-suction injection pump.
The anti-air refluence formula air guide sleeve of self-suction injection pump of the present invention, its described anti-air refluence catch are the laterally anti-air refluence catch built in the runner mouth.Laterally anti-air refluence catch blocks a runner mouth, and the gas of pump housing water outlet can not be got in the impeller.Its described anti-air refluence catch is built in the vertically anti-air refluence catch of the outlet of guiding gutter outlet.The vertical anti-air refluence catch of outlet cuts off guiding gutter, though the gas of pump housing water outlet can get into the runner mouth, can not arrive in the impeller.Its described anti-air refluence catch is built in the vertically anti-air refluence catch in the middle part at guiding gutter middle part, that is to say that anti-air refluence catch can block the air refluence and get in the impeller built in any one position of guiding gutter.Its described anti-air refluence catch is that a guiding gutter has been lacked at the top that is equivalent to guiding gutter like this built in the vertically anti-air refluence catch of the inlet of guiding gutter inlet, blocks the air refluence and gets in the impeller.
