Description
Technical field
The present invention relates to self-suction injection pump, particularly relate to the baffle plate that the air-prevention of self-suction injection pump air guide sleeve flows backwards, belong 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 arranged in the pump housing, after the driven by motor wheel rotation, produce high pressure, the air in pump and pipeline, liquid are by in water intake and flaring jet pipe intake impeller, get back to again the water outlet of the pump housing through the guiding gutter in 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 with the runner mouth, gas, liquid flow to the water outlet of pump through the runner mouth of air guide sleeve.Be generally 5 guiding gutters in an air guide sleeve, corresponding runner mouth is also 5, and water outlet (top is conducive to Bas Discharged) on the wall of the pump housing, one place's runner mouth is often arranged facing to pump housing water outlet, although 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 pump housing water outlet to impeller, so seriously affect the self-priming effect of self-suction injection pump.Therefore, the inventor had once developed the air-prevention backflow-type 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 self-suction injection pump is large, must reach tubaeform jet pipe above, otherwise the water surface does not seal air, affects the 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 the outside from water outlet, can cause erroneous judgement, think that water filled with foot, and actual irrigation quantity is not enough, does not reach requirement.
Summary of the invention
The objective of the invention is in order to overcome the shortcoming of prior art existence, 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 backflow, the baffle plate that the air-prevention 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 air-prevention of self-suction injection pump air guide sleeve of the present invention 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, be connected by tubaeform jet pipe between pump chamber in air guide sleeve and the pump housing, the pump housing is shaped with water intake and water outlet, water intake connects intake pipe, water outlet connects outlet pipe, air guide sleeve is shaped with guiding gutter, be shaped with 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 air-prevention flows backwards outward, described baffle plate is shaped with mounting hole at the center, mounting hole matches with the outer wall of tubaeform jet pipe head, outwards make successively circular flat and conical surface from mounting hole, there is arc transition the boundary of circular flat and conical surface, the outer wall of baffle plate is shaped with circular stiffening rib and straight line stiffening rib, the edge of baffle plate is shaped with outerplanar and inner plane, baffle plate is shaped with the flowing water mouth, flowing water mouth limit mouth is shaped with water guiding strip in a side of inwall, the inner dead point of water guiding strip is positioned at the intersection of circular flat and conical surface.
The invention discloses a kind of baffle plate of air-prevention 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 pipeline, liquid are by in water intake and flaring jet pipe intake impeller, get back to the water outlet of the pump housing (from out gas of guiding gutter, pump chamber that liquid arrives first the pump housing through the guiding gutter in 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) air-prevention flows backwards is set independently outside air guide sleeve, the baffle plate gear that air-prevention flows backwards is in the outside of air guide sleeve, keeping off the water outlet of the pump housing, baffle plate is shaped with the flowing water mouth, and the flowing water mouth is in the pump chamber bottom, effectively prevent the gas backflow of pump housing water outlet to impeller, improve the self-priming effect of self-suction injection pump.described baffle plate is shaped with mounting hole at the center, the mounting hole of baffle plate is connected mesopore and is connected with the head of tubaeform jet pipe together with air guide sleeve, assemble laborsaving, outwards make successively circular flat and conical surface (cirque body and cone) at the mounting hole of baffle plate, make between baffle plate and air guide sleeve gapped, but both are adjacent to each other again, keep corresponding spacing, have a common boundary at circular flat and conical surface and be arc transition, 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 with the flowing water mouth, the flowing water mouth in the pump housing below, under water, sealing air passes through, reduce front the pouring water of start (feeding water) amount, water level only gets final product below tubaeform jet pipe, reduce labor intensity, avoid again water to be splashed to the outside from water outlet, create a false impression, the flowing water mouth has water guiding strip, be conducive to flowing of water.
The baffle plate that the air-prevention of self-suction injection pump air guide sleeve 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.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.
