Abstract
The utility model relates to a two-stage lead-in sealing device for the submersible motor cable. The -two-stage lead-in sealing device for the submersible motor cable comprises a single-stage outlet box 1, a single-stage expansion ring 2, a single-stage packing washer 3, a single-stage hold-down bolt 4, a two-stage outlet box 5, a two-stage expansion ring 6, a two-stage packing washer 7, a two-stage hold-down bolt 8, a protective jacket 9, an o-shaped sealing ring and a bolt 11. Due to a set of cable lead-in sealing devices is added in the submersible motor cable two-stage lead-in sealing device in the utility model, after the elastic deformation of the expansion ring 2 and 6 and the rubber protective jacket of cable 12 is simultaneously generated, through the pretightening force of the hold-down bolt 4 and 8 compressing the expansion ring 2 and 6 by the acting force of packing washer 3 and 7, thus an effective two-stage sealing systems which can be simultaneously acted are formed, thereby the problem of short circuit burning and electric leakage wounding and dissipation of energy resulted from the failure of the submersible motor cable lead-in sealing device is effectively solved, and the service life of the submersible motor is prolonged.
Description
Technical field
The utility model technology relates to submersible motor, particularly a kind of multilevel introducing and sealing device for diving generator cable, after it can effectively solve rubber sleeve flexible cable line rubber sheath and long-time compression fatigue of piston ring and cable that aging distortion causes introducing seal failure, and submersible motor was dived under water deeply (surpass 5m) and during overlong time, under the pressure effect of deep water position, water infiltrates through wiring chamber/motor room along the cable periphery and machine and problems such as electric leakage is hurted sb.'s feelings, power consumption are burnt in the short circuit that causes.
Background technology
At present, well-known diving generator cable is introduced sealing device and is made up of the outlet box on the support, piston ring, packing washer and hold-down bolt, be installed in outlet box on the support after, usefulness securing member and O-ring seals fit sealing.It is to produce pretightning force by the locking hold-down bolt that cable is introduced sealing, active force compression piston ring by packing washer, piston ring and cable rubber sheath produce the strain sealing jointly, that is: the outer rubber sheath of piston ring and cable, the piston ring conical surface and the packing washer conical surface, the piston ring conical surface and the outlet box conical surface, tensioner under elasticity of compression metamorphosis forms the sealing system of a face and face jointly.Not under compression fatigue and the aging situation, this sealing system can also play good sealing effectiveness at piston ring and cable rubber sheath.But, along with the submersible motor prolongation of service time, and even under the HTHP effect that produces during motor rotation, diving depth dark excessively (surpass 5m) even, the long compression fatigue of piston ring and cable reaches to wear out and causes hold-down bolt to become flexible (pretightning force fades away), the random variation of the ambient pressure of cable entry, and cause press water to infiltrate through the motor room along the cable periphery, cause short circuit burning machine and problems such as electric leakage is hurted sb.'s feelings, power consumption.
Summary of the invention
The purpose of this utility model is the above-mentioned deficiency that overcomes prior art, and provide a kind of multilevel introducing and sealing device for diving generator cable, it can not only remedy the cable single-stage and introduce the long-time compression fatigue of sealing device, the aging and caused seal failure of sealing device environment for use, and can be after the cable first order be introduced the sealing device inefficacy, still can guarantee the work that submersible motor is continual and steady, prolong the useful life of submersible motor greatly, solved the darkest problem that does not allow to surpass the national regulation scope of submersible motor diving depth simultaneously.
The technical solution of the utility model is: a kind of multilevel introducing and sealing device for diving generator cable, it is on the single-stage cable introduced seal device, has increased one or more sets cable introduced seal devices.
The further technical scheme of the utility model is: a kind of multilevel introducing and sealing device for diving generator cable, it comprises the one-level outlet box, the one-level piston ring, the one-level packing washer, the one-level hold-down bolt, the secondary outlet box, the secondary piston ring, the secondary packing washer, the secondary hold-down bolt, sheath, O-ring seals and bolt, one-level piston ring and one-level packing washer are installed on the one-level outlet box by the one-level hold-down bolt, the secondary outlet box is installed on the one-level outlet box by O-ring seals and bolt, and secondary piston ring and secondary packing washer are installed on the secondary outlet box by secondary hold-down bolt and sheath.
The further technical scheme of the utility model also can be: a kind of diving generator cable two-stage is introduced sealing device, it comprises the one-level outlet box, the one-level piston ring, the one-level packing washer, the one-level hold-down bolt, the secondary outlet box, the secondary piston ring, the secondary packing washer, the secondary hold-down bolt, three grades of outlet boxes, three grades of piston rings, three grades of packing washers, three grades of hold-down bolts, sheath, O-ring seals and bolt, one-level piston ring and one-level packing washer are installed on the one-level outlet box by the one-level hold-down bolt, the secondary outlet box is installed on the one-level outlet box by O-ring seals and bolt, secondary piston ring and secondary packing washer are installed on the secondary outlet box by the secondary hold-down bolt, three grades of outlet boxes are installed on the secondary outlet box by O-ring seals and bolt, and three grades of piston rings and three grades of packing washers are installed on three grades of outlet boxes by three grades of hold-down bolts and sheath.
The utility model is owing to introduce on the sealing device in the diving generator cable single-stage; one or more sets cable introduced seal devices have been increased; having overcome the cable single-stage introduces the unfavorable factor of the internal and external environment of sealing device (single-stage system directly separates motor chamber and environment for use on every side; and just pressure drop is handed in the deep water position of directly standing interior HTHP of motor chamber and diving depth; rubber-like parts compression fatigue and aging acceleration the); and after after first order cable is introduced the long-time compression fatigue of sealing and worn out, losing efficacy; the role who continues to take on protection was (though first order sealing was lost efficacy; but still hand over just pressure drop to play certain filtration to the deep water position of medium-sized submersible motor diving depth; second level sealing heavily ensures with extraneous the contact with regard to many one); efficiently solving the short circuit burning machine and the electric leakage that cause because of diving generator cable introducing sealing device inefficacy back infiltration hurts sb.'s feelings; problems such as power consumption; improve the security performance of submersible motor greatly, prolonged the useful life of submersible motor.
