The utility model provides a seal an enhancement seal structure of prevention of seepage stream of hyperfilevation booster pump effectual, long service life.
Description
[technical field]
The utility model relates to the reinforcement sealing structure of the anti-seepage flow about a kind of reverse osmosis suction booster.
[background technique]
At present, the diaphragm type booster pump in the water purifior on market, the product bad phenomenon such as seepage, pressure exception on the low side still exist.The reason that these phenomenons occur, often be not good enough in structural design.Escapement bearing support is provided with screw, diaphragm body and escapement are provided with through hole, diaphragm body is placed on escapement bearing support, escapement is placed in above diaphragm body afterwards, recycling screw is each passed through the through hole on diaphragm body and escapement afterwards, then is locked in the screw on wheel bearing support.So in use, escapement bearing support, diaphragm body and escapement constantly vibrate, and the water in pump chamber infiltrates from the through hole diaphragm body and escapement, then oozes out from the surface escapement bearing support, thus having the globule to enter in motor, the water of infiltration is many will make motor damage.
The working principle of diaphragm type booster pump is: rotor rotates, and drive bias to wave wheel motion, bias is waved wheel and is fixedly connected on diaphragm, under waving the effect of wheel, is the to-and-fro motion that bias waves wheel by the convert rotational motion of motor in bias.Diaphragm is to-and-fro motion vertically, thus back and forth changes water pump volume, and import forms vacuum dehydration, outlet mineralization pressure, thus is constantly gone out by water pump.
[model utility content]
The purpose of this utility model is the reinforcement sealing structure overcoming the deficiencies in the prior art and provide the anti-seepage flow of a kind of reverse osmosis suction booster of a kind of good sealing effect, long service life.
For above-mentioned purpose, the utility model by the following technical solutions:
A kind of reinforcement sealing structure of anti-seepage flow of reverse osmosis suction booster, it is characterized in that comprising the annular groove 2 be located on escapement bearing support 1 and the annular boss 4 being located at protrusion downwards bottom diaphragm body 3, in annular groove 2, be placed with O-ring seal 5, described annular boss 4 to snap in annular groove 2 and is pressed on O-ring seal 5; First ring form drag stream boss 6 is provided with at the screw periphery of escapement bearing support 1 upper surface, the periphery of the screw perforation of escapement 7 lower surface is provided with the second annular choked flow boss 8, and the annular choked flow boss 8 of first ring form drag stream boss 6, second is pressed on lower surface, the upper face of diaphragm body 3 respectively.
More excellent, bottom described annular groove 2, be provided with annular convex rib 9, O-ring seal 5 is pressed on annular convex rib 9.
More excellent, described first ring form drag stream boss 6 is different from the internal diameter of the second annular choked flow boss 8 and formed and misplace.
The beneficial effects of the utility model have:
This case is placed with O-ring seal in annular groove, and described annular boss to snap in annular groove and is pressed on O-ring seal, and annular boss, just as a sealing plug, is embedded in annular groove, makes it to form first sealing.
In addition, first ring form drag stream boss, the second annular choked flow boss are pressed on lower surface, the upper face of diaphragm body respectively, and first ring form drag stream boss is different from the internal diameter of the second annular choked flow boss and formed and misplace; This misconstruction well takes precautions against escapement in whole working procedure, particularly takes precautions against the infiltration phenomenon in escapement tilting procedure, makes it to form second sealing.
Its three, bottom described annular groove, be provided with annular convex rib, O-ring seal is pressed on annular convex rib, this just makes first sealing the inside further enhance, fitted seal cushion rubber, can tackle escapement and significantly swing the spatial variations causing sealing position, make it formation three seals.

[embodiment]
Below in conjunction with accompanying drawing and embodiment, the utility model is elaborated:
As shown in the figure, a kind of reinforcement sealing structure of anti-seepage flow of reverse osmosis suction booster, include a kind of reinforcement sealing structure of anti-seepage flow of reverse osmosis suction booster, comprise the annular groove 2 be located on escapement bearing support 1 and the annular boss 4 being located at protrusion downwards bottom diaphragm body 3, in annular groove 2, be placed with O-ring seal 5, described annular boss 4 to snap in annular groove 2 and is pressed on O-ring seal 5.As shown in Figure 1, even if the water like this in pump chamber infiltrates from the through hole diaphragm body and escapement, under the baffle seal effect of O-ring seal 5, water can not from the surface escapement bearing support, and the globule can not enter in motor, plays the effect of first sealing.
In addition, first ring form drag stream boss 6 is provided with at the screw periphery of escapement bearing support 1 upper surface, the periphery of the screw perforation of escapement 7 lower surface is provided with the second annular choked flow boss 8, the annular choked flow boss 8 of first ring form drag stream boss 6, second is pressed on lower surface, the upper face of diaphragm body 3 respectively, under the acting in conjunction of the annular choked flow boss 8 of first ring form drag stream boss 6, second, stop water to infiltrate from escapement bearing support surface and form sealing.And first ring form drag stream boss 6 is different from the internal diameter of the second annular choked flow boss 8 and formed and misplace; This misconstruction well takes precautions against escapement in whole working procedure, particularly takes precautions against the infiltration phenomenon in escapement tilting procedure, makes it to form second sealing.
More excellent, bottom described annular groove 2, be provided with annular convex rib 9, O-ring seal 5 is pressed on annular convex rib 9.This just makes first sealing the inside further enhance, and fitted seal cushion rubber, can tackle escapement and significantly swing the spatial variations causing sealing position, make it formation three seals.
In sum, three seals is to end from the direction of possibility seepage, and from the front of assembling to the back side, from axially to radial direction, from the outermost surface sealed to internal layer, all more than substance seals, so good sealing effect.On structure also, this structure makes produce near diaphragm and its screw fastening place better to seal; And when escapement significantly swings, diaphragm regional area near the screw fastening place of diaphragm, better fixed, there will not be the relative movement of diaphragm in-plane, avoid diaphragm regional area and occur relative movement, produce damage by friction diaphragm, thus affect life of product.Sealing sealing structure part is also less, produces assembling easily, and the reliability of assembling might as well.
