Abstract
The invention discloses a submerged pump cable sealing device which comprises a pressing nut, a cable moulded-on plug, a cable connector and a shell. An installation hole is formed in the shell. The cable moulded-on plug is arranged in the installation hole. The bottom end of the pressing nut abuts against the upper portion of the cable moulded-on plug. The cable connector is arranged on the lower side of the cable moulded-on plug. A groove is formed in the outer wall of the cable connector in the circumferential direction. A sealing body is arranged in the groove. First sealing is achieved through the sealing body and the shell. Second sealing is achieved through the cable moulded-on plug and the shell. The submerged pump cable sealing device is simple in structure, the higher sealing level is achieved through two-stage sealing, and meanwhile detaching, assembling and maintaining are convenient.
Description
Technical field
The present invention relates to a kind of cable seal structure, be 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 when installation and maintenance in addition, when design, toward contact, will consider its easy-to-dismount effect, 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.
Summary of the invention
The present invention seeks to provide in order to overcome the deficiencies in the prior art a kind of cable sealing device of submersible pump.
For achieving the above object, the technical solution used in the present invention 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 by 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.
Cable sealing device of submersible pump of the present invention is reasonable in design, simple in structure, by two-stage, is sealed and is reached good sealing effect, and dismounting is simultaneously easy to maintenance.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solution of the present invention is described further.
Accompanying drawing 1 is sealed structural representation of the present invention.
Accompanying drawing 2 is cable adapter schematic diagram of the present invention.
embodiment
Below in conjunction with drawings and the specific embodiments, the present invention is described in further detail.
As depicted in figs. 1 and 2, cable sealing device of submersible pump of the present invention 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 is housed in groove and fills 3, during 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 by rubber material.
During 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 with gland nut 1, be locked, 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 preferred embodiment of the present invention, and as alternatively, in above-described embodiment, the first seal also can be processed formation by encapsulating.
Above-described embodiment is only explanation technical conceive of the present invention and feature; its object is to allow person skilled in the art can understand content of the present invention and be implemented; can not limit the scope of the invention with this; all equivalences that Spirit Essence is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
