Abstract
(B, ) mining power cable gas tightness inspection device (b) comprises the sleeve pipe that admits air, cable clamp sleeve and sealing washer, the ladder chamber U -shaped cover of sleeve pipe for taking flange that admit air, the less diameter in ladder chamber matches with the external diameter of cable, the great diameter in ladder chamber matches with the external diameter of sealing washer, the internal diameter of sealing washer also matches with the external diameter of cable, flange is taken at middle part at the cable clamp sleeve, the sheathed tube top is equipped with the interface that admits air admitting air, the flange of sheathed tube flange and cable clamp sleeve admit air during the assembly through bolted connection and make the cable compress tightly bushing portion to divide and stretching the intraductal crush seal circle of cover that admits air and cause sealing washer elastic deformation, thereby make the cable outer peripheral face and the internal surface of sealing washer form airtight, airtight of the inner shape of face one -tenth of terminal surface and the great diameter department in ladder chamber before the sealing washer. The utility model discloses can the row of realization the airtight experiment of complete machine of the electrified cable of husky immersible pump, discover the trouble hidden danger that the water pump hides in advance.
Description
Technical field
The utility model relates to a kind of pick-up unit, particularly a kind of
mining power cable air tightness checking device, be applicable to the repairing of submersible pump power cable and the soak technology for detection before running and mine emergency drainage disaster-relief water pump testing.
Background technology
At present, mine emergency drainage disaster relief major equipment is Large diving pump, and new equipment or overhaul are dispatched from the factory and carried out technical feature detection, when doing motor tightness test, can only close inflation (topping up) in the past test its impermeability or withstand voltage test at the entrance of cable coupling box.Supporting power cable does submerging test separately, does not do tightness test and Salt tolerance.And at the scene of speedily carrying out rescue work, equipment does not do band line integral waterproofing tightness test yet after accessing cable in a pre-installation.By the fault disassembling analysis of the sand-discharging submerged pump to the mine emergency drainage disaster relief, find that the fault of 15% is the mechanical fault tilting to install, and starting current and voltage failure cause; The reason of more than 85% is that cable and explosive-proof sealed cause electrical machine insulation rapid drawdown to puncture soaking or slipping into infiltration when the degree of depth increases, even scaling loss and disorderly closedown.It can thus be appreciated that, do band line integral waterproofing tightness test after cable is accessed in a pre-installation to equipment and be very important, therefore, design a kind of access cable in a pre-installation for equipment after do band line integral waterproofing tightness test
mining power cable air tightness checking device, be the current technical issues that need to address.
Summary of the invention
Technical problem to be solved in the utility model be to provide a kind of access cable in a pre-installation for equipment after do band line integral waterproofing tightness test
mining power cable air tightness checking device.It can realize the airtight experiment of complete machine of sand-discharging submerged pump tape cable, finds the potential faults that sand-discharging submerged pump is hidden in advance, thus realizes the nondestructive test of equipment and reduce its run time fault outage rate, realizes the continuous reliability service of safe non-fault of equipment.
The technical scheme in the invention for solving the technical problem is:
mining power cable air tightness checking device, by air inlet sleeve pipe, cable clamp sleeve and O-ring seal composition, described air inlet sleeve pipe is the stepped cavity U-shaped cover of band joint flange, the small diameter of stepped cavity mates with the external diameter of cable, the larger diameter of stepped cavity is mated with the external diameter of O-ring seal, the internal diameter of O-ring seal also mates with the external diameter of cable, at the middle part band joint flange of cable clamp sleeve, intake interface is provided with at the top of air inlet sleeve pipe, during assembling, the joint flange of air inlet sleeve pipe and the joint flange of cable clamp sleeve are bolted and make cable clamp sleeve part put in crush seal circle in air inlet sleeve pipe and cause O-ring seal elastic deformation, thus make the inside surface of cable outer peripheral face and O-ring seal form hermetic seal, the inner face at the larger diameter place of O-ring seal front end face and stepped cavity forms hermetic seal.
As a kind of preferred version of the present utility model, between O-ring seal and cable clamp sleeve, be provided with metal gasket.
As a kind of preferred version of the present utility model, cable clamp sleeve there is screw hole, in screw hole, is installed with jackscrew.
As a kind of preferred version of the present utility model, the internal diameter of O-ring seal is less than the external diameter of cable, and the magnitude of interference is 8% of the outside diameter of cable, the outside diameter of cable and O-ring seal generation plastic yield, mutually compresses the sealing forming outside diameter of cable face and O-ring seal inner headed face.
Compared with prior art, because internal diameter of the seal ring is less than the outside diameter of cable, the magnitude of interference makes the outside diameter of cable and O-ring seal generation plastic yield, mutually compresses the sealing forming outside diameter of cable face and plantation rubber cover inner headed face.The airtight experiment of complete machine of sand-discharging submerged pump tape cable can be realized, find the potential faults that water pump is hidden in advance, realize the nondestructive test of equipment and reduce its run time fault outage rate, realizing the continuous reliability service of safe non-fault of equipment.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
