Abstract

The utility model provides a sand prevention and pressure reduction sealing device for a submersible pump. A rubber pad and a static friction block are fixedly connected to the bottom opening part of a sealing seat. A movable friction block, a spring connecting seat, and a sealing rubber ring are sheathed on an outer body of a shaft sleeve of a rotor shaft of a motor. A spring is arranged on the spring connecting seat. Buckling covering type sand prevention and pressure reduction rubber bowls are covered and connected to the sealing rubber ring and the top of the shaft sleeve. The buckling covering type sand prevention and pressure reduction rubber bowls are inwards bent type bottom opening edges, and the inwards bent type bottom opening edges and an outer body of a conical cylinder of a sealing seat are matched and connected. The movable friction block and the static friction block are connected in a movable fit mode. The sand prevention and pressure reduction sealing device for a submersible pump has novel structure, strict match, strong sealing performance, durability, and convenient use. The utility model is a novel sand prevention and pressure reduction sealing device for a submersible pump.

Description

The sand prevention reduced pressure sealing device of submersible pump
Technical field
The utility model relates to a kind of parts of liquid pump, especially the air locking of submersible pump.
Background technique
Along with the continuous development of submersible pump, its sealability also needs correspondingly to improve, because the air locking of submersible pump is directly connected to the working efficiency of pump and working life etc.In known technology, existing submersible pump sand prevention sealed attachment parts mainly are made up of sealing seat, metal sand prevention circle, O-ring seal, axle sleeve, the axle sleeve of load and O-ring seal are joined and are connected the motor for submerged pump rotor shaft in sealing seat, because rotor high speed rotating operation, only depend on the single O-ring seal seal action that loses more easy to wear, even water inlet burns out motor, working life is short, and metal sand prevention circle is with empty big between sealing seat cooperates, dustproof effect is poor, especially when the submersible pump operation stopped, its sealing sand prevention poor performance made troubles for the use of pump.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of improved submersible pump sand prevention sealer, make its have novel structure, cooperate tight, can prevent effectively that foreign material such as silt from entering in rotor axle sleeve and the sealer, improve pump working life, pump is worked safely and efficiently.
The technological scheme that its technical problem that solves the utility model adopts is: sealing gasket and static friction block are connected in sealing seat, suit mobile friction block, spring connection frame and O-ring seal on the axle sleeve ectosome, on the spring connection frame spring is housed, at the top of O-ring seal and axle sleeve load button bowl bell-type sand prevention decompression glue bowl, the end mouth of glue bowl is along being connected with sealing seat, mobile friction block is connected movingly with static friction block, and the piece that rubs that consists of adds the multidigit fitted seal formula sand prevention reduced pressure sealing device of rubber cushion, glue bowl.During assembling, sealing seat of the present utility model is installed on the submersible pump water inlet joint, installs rotor axis of electric in the axle sleeve.During operation, the related axle sleeve of rotor axis of electric, mobile friction block, spring linked base, spring, seal rubber pad and sand prevention decompression glue bowl rotate synchronously, sand prevention decompression glue bowl gets rid of silt under the rotary centrifugal force effect and takes off, and is sealed movingly closely by spring action mobile friction block and static friction block; When fulfiling assignment termination of pumping, seal in week at the bottom of the sand prevention decompression glue bowl along holding the sealing seat conic tube tightly.
Because technique scheme has been adopted in the utility model design, through testing on probation showing, it has novel structure, cooperates advantages such as tight, that sealing is strong, durable in use, easy to use, is a kind of novel sand prevention reduced pressure sealing device of submersible pump.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the sectional view of the utility model embodiment concrete structure.
Fig. 2 is the worm's eye view of sand prevention decompression glue bowl among Fig. 1.
Fig. 3 is the worm's eye view of mobile friction block among Fig. 1.
Fig. 4 is the plan view of static friction block among Fig. 1.
Reference character: 1 rubber cushion, 2 static friction blocks, 3 mobile friction blocks, 4 axle sleeves, 5 O-ring seals, 6 sand prevention decompression glue bowl, 7 springs, 8 spring linked bases, 9 sealing seats, 10 rotor axis of electric.
Embodiment
Embodiment as shown in Figure 1, the utility model comprises: sealing seat 9, sealing gasket 1, static friction block 2, mobile friction block 3, axle sleeve 4, O-ring seal 5, sand prevention decompression glue bowl 6, spring 7, spring linked base 8.At the endoporus bottom opening of sealing seat 9 be connected rubber cushion 1 and static friction block 2, suit mobile friction block 3, spring linked base 8 and O-ring seal 5 on axle sleeve 4 ectosomes of rotor, and spring 7 is housed on spring linked base 8, at the main header casing of O-ring seal 5 and the axle sleeve 4 button bell-type sand prevention decompression glue bowl 6 of ining succession, glue bowl 6 is connected along the outer body of conical drum with sealing seat 9 for mouth at the bottom of the inner curved, and 2 liang of faces that rub of mobile friction block 3 and static friction block are connected movingly.
