Description
Technical field
The present invention relates to self-suction injection pump, particularly relate to the baffle plate of the air-prevention refluence of self-suction injection pump kuppe, belong to water pump field.
Background technology
Self-suction injection pump is by driven by motor impeller, impeller outer has kuppe, kuppe is arranged in the pump housing, when after driven by motor wheel rotation, produce high pressure, air in pump and pipeline, liquid are by water inlet and flaring jet pipe intake impeller, get back to again the delivery port of the pump housing through the guiding gutter in kuppe, flow in order to be conducive to the smooth and easy of guiding gutter, at the opening part of guiding gutter, guiding gutter is shaped with to runner mouth, gas, liquid flow to the delivery port of pump through the runner mouth of kuppe. In a kuppe, be generally 5 guiding gutters, corresponding runner mouth is also 5, and delivery port (top is conducive to Bas Discharged) on the wall of the pump housing, often there is place's runner mouth facing to pump housing delivery port, although the rotation of impeller makes gas, liquid flow toward the direction all the time, but in the time of real work, the guiding gutter of pump housing delivery port one side there will be air refluence (pouring in down a chimney) phenomenon, can, the gas suck-back outside pump housing delivery port to impeller, so seriously affect self-priming effect of self-suction injection pump. Therefore, the inventor had once developed the air-prevention backflow-type kuppe of self-suction injection pump, and apply for Chinese patent, the patent No. is ZL200910101398.7, the kuppe of multiple technologies schemes is provided in this patent, adopt such kuppe can prevent that air from flowing backwards, and improves self-priming effect of self-suction injection pump. But still there is a shortcoming in the self-suction injection pump after kuppe improves, open exactly pouring water before self-suction injection pump (feed water) amount large, must reach tubaeform jet pipe above, otherwise the water surface does not seal air, affects self-priming effect. Be in when operation on the other hand, because the face of pouring water in pump is high, priming charge can be splashed to outside from delivery port, can cause erroneous judgement, think that water filled with foot, and actual irrigation quantity deficiency does not reach requirement.
Summary of the invention
The object of the invention is the shortcoming existing in order to overcome prior art, provide a kind of irrigation quantity little, reduce labor intensity, easy to operate, can effectively prevent that again the pump housing delivery port from producing gas backflow, improve the baffle plate of the air-prevention refluence of the self-suction injection pump kuppe of self-suction injection pump self-priming effect.
The technical scheme of the baffle plate that the air-prevention of self-suction injection pump kuppe of the present invention flows backwards is: comprise motor, the pump housing, impeller, kuppe and tubaeform jet pipe, the end cap of motor connects the pump housing, motor shaft impeller, impeller outer has kuppe, between pump chamber in kuppe and the pump housing, be connected by tubaeform jet pipe, the pump housing is shaped with water inlet and delivery port, water inlet connects water inlet pipe, delivery port connects outlet pipe, kuppe is shaped with guiding gutter, be shaped with runner mouth in guiding gutter exit, described guiding gutter is 5, corresponding runner mouth is 5, it is characterized in that: described kuppe arranges the baffle plate that air-prevention flows backwards outward, described baffle plate is shaped with installing hole at center, installing hole matches with the outer wall of tubaeform jet pipe head, outwards make successively circular flat and taper seat from installing hole, there is arc transition the boundary of circular flat and taper seat, the outer wall of baffle plate is shaped with circular reinforcement and straight line reinforcement, the edge of baffle plate is shaped with outerplanar and inner plane, baffle plate is shaped with flowing water mouth, flowing water mouth limit mouth is shaped with flow guide bar in a side of inwall, the inner dead point of flow guide bar is positioned at the intersection of circular flat and taper seat.
The invention discloses a kind of baffle plate of air-prevention refluence of self-suction injection pump kuppe, when work, starter motor, after motor shaft impeller is rotated, produce high pressure, air in pump and pipeline, liquid are by water inlet and flaring jet pipe intake impeller, the delivery port of getting back to the pump housing through the guiding gutter in kuppe is again (from gas out of guiding gutter, pump chamber that liquid arrives first the pump housing, the delivery port of the runner pump housing is discharged again, so delivery port is built in the top of the pump housing), discharge from outlet pipe. the principal character of the technical program is that the baffle plate that (not being the improvement design to kuppe body) air-prevention flows backwards is set independently outside kuppe, the baffle plate gear that air-prevention flows backwards is in the outside of kuppe, keeping off the delivery port of the pump housing, baffle plate is shaped with flowing water mouth, and flowing water mouth is in pump chamber bottom, effectively prevent that the gas backflow of pump housing delivery port is to impeller, improve self-priming effect of self-suction injection pump. described baffle plate is shaped with installing hole at center, the installing hole of baffle plate is connected with the head of tubaeform jet pipe together with the mesopore of kuppe, assemble laborsaving, outwards make successively circular flat and taper seat (torus and cone) at the installing hole of baffle plate, make between baffle plate and kuppe gapped, but both are adjacent to each other again, keep corresponding spacing, have a common boundary for arc transition at circular flat and taper seat, improve the intensity of junction, attractive in appearance again, baffle plate outer wall has circular and straight line reinforcement, improve baffle plate bulk strength, reduce wall thickness, outside baffle edge is made, inner plane, reduce resistance to water-flow, baffle plate is shaped with flowing water mouth, flowing water mouth in the pump housing below, under water, sealing air passes through, reduce pouring water before start (feeding water) amount, water level is only below tubaeform jet pipe, reduce labor intensity, avoid again water to be splashed to outside from delivery port, create a false impression, flowing water mouth has flow guide bar, be conducive to flowing of water.
The baffle plate that the air-prevention of self-suction injection pump kuppe of the present invention 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. Flowing water mouth can be one or several. The height H of described flow guide bar is 1-5mm. Flow guide bar has enough height, makes flowing water more smooth and easy.
