Description
Technical field
The utility model relates to a kind of cable seal structure, is specifically related to a kind of cable sealing device of submersible pump.
Background technique
Because the special Environmental Conditions of submersible pump requires its higher grade of cable seal, therefore the sealing of submersible pump cable is one of emphasis of submersible pump structural design, submersible pump cable line often needs dismounting in the time of installation and maintenance in addition, in the time of design, will consider its easy-to-dismount effect toward contact, and the cable sealing device of submersible pump of prior art is often because unreasonable structure causes sealing difference or the defects such as inconvenient are installed.
Model utility content
The utility model object is that a kind of cable sealing device of submersible pump is provided in order to overcome the deficiencies in the prior art.
For achieving the above object, the technical solution adopted in the utility model is: a kind of cable sealing device of submersible pump, described sealing configuration comprises gland nut, elastic cable paper molded plug, cable adapter and housing, described housing is arranged on described submersible pump, on described housing, be formed with mounting hole, described elastic cable paper molded plug is arranged in described mounting hole, described gland nut bottom is resisted against the top of described elastic cable paper molded plug, described cable adapter is arranged on the downside of described elastic cable paper molded plug, on described cable adapter outer wall circumferencial direction, be formed with groove, in described groove, be provided with seal, described seal and described housing form the first sealing, described elastic cable paper molded plug and described housing form the second sealing.
Preferably, described seal is O RunddichtringO.
Preferably, described seal is that encapsulating is processed the seal forming.
Preferably, described elastic cable paper molded plug is made up of rubber material.
Preferably, the outer surface of described elastic cable paper molded plug and the internal surface of described mounting hole are threaded
Preferably, described cable adapter contains at least one contact pin, and expose at described contact pin two ends, and described contact pin upper end is connected with the pin holes on described elastic cable paper molded plug, and the pin holes in described contact pin lower end and submersible pump is electrically connected.
Preferably, on described cable adapter, be provided with positioning boss.
Preferably, the quantity of described contact pin is three.
The utility model cable sealing device of submersible pump is reasonable in design, simple in structure, is sealed and is reached good sealing effect by two-stage, and dismounting is simultaneously easy to maintenance.
Brief description of the drawings
Below in conjunction with accompanying drawing, technical solutions of the utility model are described further.
Accompanying drawing 1 is the utility model sealed structural representation.
Accompanying drawing 2 is cable adapter schematic diagram of the present utility model.
embodiment
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
As depicted in figs. 1 and 2, the utility model cable sealing device of submersible pump is mainly used in electric connection and the sealing of motor in submersible pump cable line and submersible pump, described sealing configuration comprises gland nut 1, elastic cable paper molded plug 2, cable adapter 4 and housing 5, described housing 5 is submersible pump shell, on described housing, be formed with mounting hole 6, described gland nut 1, elastic cable paper molded plug 2 and cable adapter 4 are arranged in described mounting hole 6, and realize sealing.
As shown in Figure 2, cable adapter 4 is media that elastic cable paper molded plug 2 and motor for submerged pump are electrically connected, be placed in the below of described elastic cable paper molded plug 2, in described cable adapter 4, be provided with three contact pins 41, three contact pins are uniformly distributed with spacing at a certain angle, expose at contact pin two ends, upper end is connected with the pin holes of elastic cable paper molded plug 2, lower end is connected with the motor down-lead pin holes of submersible pump, on cable adapter 4, be also provided with positioning boss 42, prevent error damage contact pin, correspondingly, elastic cable paper molded plug 2 relevant positions are provided with positioning hole.
In conjunction with as shown in Figure 1, on cable adapter 4 outer wall circumferencial directions, be formed with O RunddichtringO groove 43, O RunddichtringO to be housed in groove and to fill 3, when installation, the compressive strain of O RunddichtringO can form the first seal.
As shown in Figure 1, gland nut 1 outer surface is threaded with the internal surface of described housing 5, and the elastic cable paper being connected with described elastic cable paper molded plug 2 is through described gland nut 1, the upper surface of elastic cable paper molded plug 2 described in the lower end abutment of described gland nut 1.
Preferably, described elastic cable paper molded plug is made up of rubber material.
When installation, first alignment pin, installs cable adapter 4, then elastic cable paper molded plug 2 is pressed in the mounting hole of cast housing, and the compressive strain of O RunddichtringO pressurized, forms the first seal; Elastic cable paper molded plug 2 is after cable adapter contact pin direction installs, finally be locked with gland nut 1, gland nut compresses and makes 2 distortion of rubber cable line molded plug form the second seal, forms two-stage sealing again, good sealing effect, and easy for installation.
Above-described embodiment is the utility model preferred embodiment, and as alternatively, in above-described embodiment, the first seal also can be processed formation by encapsulating.
Below be only concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technological scheme of formation, all drop on the utility model rights protection scope.
