Abstract
The utility model relates to a submersible electric pump cable incoming line stitching sealing structure, comprising a cable gland and an incoming line seal ring, a small gland, and a gland seal ring which are connected through the cable. The incoming line seal ring is disposed between the cable and a junction box. The cable gland tightly pressing the incoming line seal ring is fastened on the junction box. The gland seal ring is disposed between the cable and the cable gland. The small gland tightly pressing the seal ring is fastened on the cable gland. The sealing structure is novel in structure, convenient in processing, and low in production cost. The cable and the junction box are connected and stitched firmly. The sealing structure has good sealing effect. The structure effectively isolates moisture or moist air, solves problems that connection of a conventional cable and a junction box is easy to become loose, and sealing effect is easy to lose efficacy, and increases service life of diving electric devices.
Description
Technical field
The utility model relates to a kind of hermetically-sealed construction, particularly a kind of submersible electric pump cable line inlet wire pressing hermetically-sealed construction.
Background technology
The submersible electric pump cable water-tight is directly to affect submersible motor reliability key factor, and reprocessing has 70% all to be because the cable water inlet causes coil to make moist until burn in the electric pump.The main path one of cable water inlet is that damaged whose gap between core of cable sheath enters motor, the 2nd, and the damaged water of cable core enters motor along the gap between the copper wire of core inside.
Traditional submersible pump cable incoming seal is just at the terminal box place of immersible pump, by regulating hold-down bolt, carry out first compression with rubber ring, thereby come cable is sealed, it the damage of cable root easily occurs in actual use, water pump is in transportation, installation, use procedure, the water pump cable is subject to the impact of external pull, easily produce and become flexible, thereby incoming seal lost efficacy, and cause cable place water inlet, so that motor entering water, burn.
Summary of the invention
The purpose of this utility model is to overcome the problem that prior art exists, proposed a kind of simple in structure, the cable inlet wire is connected firmly, the submersible electric pump cable line inlet wire pressing hermetically-sealed construction of good sealing effect.
In order to achieve the above object, the technical solution adopted in the utility model is: a kind of submersible electric pump cable line inlet wire pressing hermetically-sealed construction, it is characterized in that comprising the cable feedthrough, incoming seal circle, little gland and the gland ring that all are connected on the cable, the incoming seal circle is arranged between cable and the terminal box, the cable feedthrough that compresses the incoming seal circle lock onto on the terminal box, gland ring is arranged between cable and the cable feedthrough, and the little gland that compresses gland ring lock onto on the cable feedthrough.
Be equipped with compacting ring between described gland ring and cable feedthrough, cable feedthrough and incoming seal circle, incoming seal circle and the terminal box.
Compared with prior art, the beneficial effect that the utility model reaches is: the cable cross-under is on terminal box, successively through gland ring and little gland pressing, when guaranteeing the inlet wire joint stable, can prevent effectively that sealing enters in the terminal box along the cable outer wall by incoming seal circle and gland ring.
The utility model novel structure, easy to process, production cost is low, cable and terminal box cross-under pressing are firm, good sealing effect, moisture or humid air can have effectively been completely cut off, solve the easily easy problem that lost efficacy of loosening, sealing of traditional cable and terminal box cross-under, increased the useful life of diving electric device.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure: cable 1, terminal box 2, cable feedthrough 3, incoming seal circle 4, little gland 5, gland ring 6, compacting ring 7.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
Shown in the accompanying drawing 1, a kind of submersible electric pump cable line inlet wire pressing hermetically-sealed construction comprises cable feedthrough 3, incoming seal circle 4, little gland 5 and the gland ring 6 that all is connected on the cable 1, incoming seal circle 4 is arranged between cable 1 and the terminal box 2, the cable feedthrough 3 that compresses incoming seal circle 4 lock onto on the terminal box 2, gland ring 6 is arranged between cable 1 and the cable feedthrough 3, and the little gland 5 that compresses gland ring 6 lock onto on the cable feedthrough 3; Be equipped with compacting ring 7 between gland ring and cable feedthrough, cable feedthrough and incoming seal circle, incoming seal circle and the terminal box.
Claims (2)
1. submersible electric pump cable line inlet wire pressing hermetically-sealed construction, it is characterized in that: comprise the cable feedthrough, incoming seal circle, little gland and the gland ring that all are connected on the cable, the incoming seal circle is arranged between cable and the terminal box, the cable feedthrough that compresses the incoming seal circle lock onto on the terminal box, gland ring is arranged between cable and the cable feedthrough, and the little gland that compresses gland ring lock onto on the cable feedthrough.
