Description
Technical field
The utility model relates to self-suction injection pump, particularly relates to the baffle plate of the anti-air refluence of self-suction injection pump air guide sleeve, belongs to the water pump field.
Background technique
Self-suction injection pump is by the driven by motor impeller, impeller outer has air guide sleeve, 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 by 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 be conducive to the smooth and easy of guiding gutter, at the opening of guiding gutter guiding gutter 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 is conducive to air and discharges) on the wall of the pump housing, one place's runner mouth is often arranged 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.Therefore, the inventor had once developed the anti-air refluence formula air guide sleeve of self-suction injection pump, and applied for Chinese patent, the patent No. is ZL200910101398.7, the air guide sleeve of multiple technologies schemes is provided in this patent, adopt such air guide sleeve can prevent that air from flowing backwards, and improves the self-priming effect of self-suction injection pump.Still there is a shortcoming in the self-suction injection pump after but air guide sleeve improves, and (the feeding water) amount of pouring water of opening exactly before the self-suction injection pump is big, must reach tubaeform jet pipe above, otherwise the water surface does not seal air, influences the self-priming effect.Be in when operation on the other hand, because the face height of pouring water in the pump, priming charge can be splashed to the outside from water outlet, can cause erroneous judgement, think that water irritated foot, and actual irrigation quantity deficiency does not reach requirement.
Summary of the invention
The purpose of this utility model is in order to overcome the shortcoming that prior art exists, provide a kind of irrigation quantity little, reduce labor intensity, easy to operate, can prevent effectively that again the pump housing water outlet from producing gas and flowing backwards, the baffle plate that the anti-air of the self-suction injection pump air guide sleeve of raising self-suction injection pump self-priming effect flows backwards.
The technological scheme of the baffle plate that the anti-air of the utility model self-suction injection pump air guide sleeve flows backwards is: comprise motor, the pump housing, impeller, air guide sleeve and tubaeform jet pipe, the end cap of motor connects the pump housing, the motor shaft impeller, impeller outer has air guide sleeve, linked to each other by tubaeform jet pipe between the pump chamber in air guide sleeve and the pump housing, the pump housing is shaped on water intake and water outlet, water intake connects intake pipe, water outlet connects outlet pipe, air guide sleeve is shaped on guiding gutter, be 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: described air guide sleeve arranges the baffle plate that anti-air flows backwards outward, described baffle plate is shaped on mounting hole at the center, mounting hole matches with the outer wall of tubaeform jet pipe head, outwards make circular flat and conical surface successively from mounting hole, there is arc transition the boundary of circular flat and conical surface, the outer wall of baffle plate is shaped on circular stiffening rib and straight line stiffening rib, the edge of baffle plate is shaped on outerplanar and inner plane, baffle plate is shaped on the flowing water mouth, and flowing water mouth limit mouth is shaped on water guiding strip in a side of inwall, and the inner dead point of water guiding strip is positioned at the intersection of circular flat and conical surface.
The utility model discloses a kind of baffle plate of anti-air refluence of self-suction injection pump air guide sleeve, during work, starting electrical machinery, after the motor shaft impeller is rotated, produce high pressure, the air in pump and the pipeline, liquid are by in water intake and the flaring jet pipe intake impeller, get back to the water outlet of the pump housing (the gas that comes out from guiding gutter, the pump chamber that liquid arrives first the pump housing through the guiding gutter in the air guide sleeve again, the water outlet of the runner pump housing is discharged again, so water outlet is built in the top of the pump housing), discharge from outlet pipe.The major character of the technical program is that the baffle plate that (not being the improvement design to the air guide sleeve body) anti-air flows backwards is set independently outside air guide sleeve, the baffle plate retaining that anti-air flows backwards is in the outside of air guide sleeve, keeping off the water outlet of the pump housing, baffle plate is shaped on the flowing water mouth, and the flowing water mouth is in the pump chamber bottom, the gas that prevents pump housing water outlet effectively flows backward in the impeller, improves the self-priming effect of self-suction injection pump.Described baffle plate is shaped on mounting hole at the center, the mounting hole of baffle plate is connected with the head of tubaeform jet pipe together with the mesopore of air guide sleeve, assemble laborsaving, outwards make circular flat and conical surface (cirque body and cone) successively at the mounting hole of baffle plate, make between baffle plate and the air guide sleeve gappedly, but both are adjacent to each other again, keep corresponding spacing, be arc transition at circular flat and conical surface boundary, improve the intensity of joint, attractive in appearance again, the baffle plate outer wall has circular and straight line stiffening rib, improve the baffle plate bulk strength, reduce wall thickness, outside baffle edge is made, inner plane, reduce resistance to water-flow, baffle plate is shaped on the flowing water mouth, the flowing water mouth in the pump housing below, under water, sealing air passes through, reduce preceding the pouring water of start (feeding water) amount, water level only gets final product below tubaeform jet pipe, reduces labor intensity, avoid water to be splashed to the outside from water outlet again, create a false impression, the flowing water mouth has water guiding strip, is conducive to flowing of water.
The baffle plate that the anti-air of the utility model self-suction injection pump air guide sleeve flows backwards, described flowing water mouth is more than one or one, and the width B of described flowing water mouth is 30-40mm, and length S is 20-30mm.The flowing water mouth can be one or several.The height H of described water guiding strip is 1-5mm.Water guiding strip has enough height, makes flowing water more smooth and easy.
