Description

Sealing structure on waterway booster pump

Technical Field

The utility model relates to a water route equipment, especially a seal structure on water route booster pump.

Background

The water route booster pump adopts the form of cylindricality piston to carry out pressure boost work mostly, and the back and forth motion through the piston changes the volume formation difference in the working chamber and absorbs water or gets rid of, and is higher to sealed requirement, and general sealed mode adopts a monoblock sealing rubber pad to punch and makes, and the volume is great, and the installation is difficult, has damaged, therefore we need a simple structure, sealed effectual and can optimize the seal structure of water pump work.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that a seal structure on water route booster pump is provided.

For solving the above-mentioned prior art problem, the utility model discloses a following scheme: the utility model provides a seal structure on water route booster pump, includes water pump main part, water pump piston, diaphragm, reciprocating motion around the piston is done at the downthehole piston of water pump main part driven by the inside motor of water pump main part, be equipped with the double-screw bolt on the water pump piston, the double-screw bolt is connected with the nut on the diaphragm, the piston hole is epitaxial and be located and be equipped with recess one in the water pump main part, recess one and the epaxial bead cooperation of diaphragm, be equipped with a plurality of water route pipelines in the water pump main part, water route pipeline is epitaxial and be located and be equipped with recess two in the water pump main part, two inside rubber rings that all are equipped with of recess, the.

Preferably, the nut and the diaphragm are fixed by adhesive bonding.

Has the advantages that: the utility model adopts the above technical scheme to provide a seal structure on water route booster pump, remedied the not enough of prior art, reasonable in design, convenient operation.

Detailed Description

As shown in fig. 1, 2, 3, 4, a seal structure on water route booster pump, including water pump main part 1, water pump piston 2, diaphragm 3, the inside motor of water pump main part 1 drives water pump piston 2 and is reciprocating motion around in piston hole 4, be equipped with double-screw bolt 5 on the water pump piston 2, double-screw bolt 5 is connected with nut 6 on the diaphragm 3, piston hole 4 is extensive and be located and be equipped with recess one 7 on the water pump main part 1, the cooperation of bead 8 on recess one 7 and the diaphragm 3, be equipped with a plurality of waterway pipeline 9 on the water pump main part 1, waterway pipeline 9 is extensive and be located and be equipped with recess two 10 on the water pump main part 1, the inside rubber ring 11 that all is equipped with of recess two 10, diaphragm 3 and rubber ring 11 all compress tightly on water pump main part 1 through gland 12, nut 6 passes through the adhesive bonding with diaphragm 3 and.

When in actual use, the motor in the water pump main body 1 drives the water pump piston 2 to reciprocate back and forth in the piston hole 4, so that the volumes of the piston hole 4 and the working cavity are changed, thereby sucking and discharging liquid, the utility model adopts the way that the water pump piston 2 is matched with the diaphragm 3, the liquid is isolated from the water pump piston 2 by the diaphragm 3, the liquid is prevented from soaking and corroding the water pump piston, under the condition of not influencing the work, the sealing function is realized, and through the matching of the convex edge 8 and the first groove 7, under gland 12's pressure, can provide good sealed effect around the piston hole 4, and on the same hand, rubber ring 11 also can provide good sealed effect with two 10 recesses, compare in the manufacturing approach that adopts a bold rubber pad to tailor, the utility model discloses a sealing approach save material more, the installation is simple, changes the replacement after damaging, to sum up, the utility model discloses higher practicality and novelty have.

The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications, additions and substitutions for the specific embodiments described herein may be made by those skilled in the art without departing from the spirit of the invention or exceeding the scope of the invention as defined in the accompanying claims.
