Abstract
The utility model belongs to the technical field of hydraulic machinery, and particularly relates to an improved cable sealing and fastening device for a submersible pump, which mainly comprises a cable gland and a junction box cover. The cable gland and the junction box cover are pressed and fixed by fastening elastic pads and bolts. The cable sealing and fastening device is characterized in that a lower cavity of the cable gland is filled with sealant, so that a sheath of a cable can be connected with various core wires into a whole; the cable is fastened in an upper cavity of the cable gland through a locking piece and a fastening screw; and an O-shaped ring is also arranged between the cable gland and the junction box cover. Compared with the prior art, the cable sealing and fastening device can realize reliable sealing, has a unique structure and high durability, and can achieve interchangeability so as to meet sealing and fastening needs of various cables.
Description
Technical field
The utility model belongs to the hydraulic machinery technical field, and what be specifically related to is a kind of improved submersible pump cable sealing and securing means of being used for.
Background technique
Existing submersible pump cable outlet sealing device, as shown in Figure 1, be to adopt cable feedthrough and connector cover, compress rubber sleeve by bolt and bullet pad, rubber sleeve axially and is directly upwards being deformed, especially radial deformation makes rubber sleeve coat the sheath external diameter of cable, blocks extraneous medium and enters in the motor cavity, reaches sealing effect.
Though this submersible pump cable outlet sealing device can play sealing effect, it also has deficiency, and its deficiency is:
1. if cable cover(ing) breakage, medium will leak in the motor cavity along the gap between each heart yearn of cable, thereby causes seal failure, causes the regular maintenance of water pump.
2. cable is understood the double swerve because of the mobile of medium in medium, and it is easy to contact with cable feedthrough and rub, thereby causes the breakage of cable cover(ing).Further cause seal failure.
3. cable can get loose because of pullling in actual use.Though cable is forbidden to pull, when transportation and installation water pump, pullling of cable is inevitably, thereby because cable is to cause its radial deformation to produce axial frictional force by the extruding rubber sleeve, so this power is less, can only overcome less pulling force.
4. its sheath external diameter difference of different model cable, this just need be according to the supporting rubber sleeve of cable model, and the rubber sleeve size is numerous and diverse, thereby causes quantity in stock bigger, and versatility is relatively poor.Its external diameter of same cable also has deviation in addition, easily causes poor sealing.
5. pretightening force is had relatively high expectations.Because the compressive plane between cable feedthrough and the rubber sleeve is bigger, need very big pretightening force when fastening, to mounting and dismounting inconvenience.
Summary of the invention
The purpose of this utility model is to propose a kind of improved submersible pump cable sealing and securing means of being used for, and is used to solve the deficiency of above-mentioned cable seal mode.
Main technical schemes of the present utility model is: mainly comprise the cable feedthrough and the connector cover that are fixed by fastening bullet pad and bolt, it is characterized in that by the perfusion sealer sheath of cable and each heart yearn being fused in the cavity under the cable feedthrough; The cable feedthrough upper plenum is interior by lock sheet and the fastening cable of Cock screw; Also be provided with O type circle between cable feedthrough and the connector cover.
The technical problem underlying that the utility model solves is as follows:
1. adopt perfusion sealer method, cable cover(ing) and each heart yearn of cable are fused.Under the situation of cable cover(ing) breakage, medium still can not enter in the motor cavity.
2. on cable cover(ing), increase locking device, promptly use the lock sheet tabula between cable feedthrough and cable cover(ing), make cable can not touch cable feedthrough, prevented the wearing and tearing of cable cover(ing).
3. on cable cover(ing), increase locking device, promptly use lock sheet locking cable sheath, guarantee that cable cover(ing) can bear certain pulling force and cable is got loose.
4. only need a universal cordage gland to get final product, to its perfusion sealer, cable can play sealing effect, realizes interchangeability and versatility, to realize the needs of multiple cable outlet sealing.
5. adopt the sealing of O type circle, pretightening force is less, and it is convenient to change, good seal performance, and the life-span is long.
The utility model compared with prior art seals reliably, and the structure uniqueness is durable in use, realizes interchangeability, to realize multiple cable seal and fastening needs.
Description of drawings
Accompanying drawing 1 is existing submersible pump cable sealing and securing means structural representation; Accompanying drawing 2 is the utility model example structure schematic representation.
In the accompanying drawing, the 1-rubber sleeve; 2-bullet pad; The 3-bolt; The 4-cable; The 5-cable feedthrough; The 6-connector cover; The 7-sealer; 8-O type circle; The 9-lock sheet; The 10-Cock screw.
Embodiment
Below in conjunction with embodiment and accompanying drawing the utility model is described in detail.
Embodiment: the utility model embodiment is used for submersible pump cable sealing and securing means, mainly comprise the cable feedthrough 5 and the connector cover 6 that are fixed by fastening bullet pad 2 and bolt 3, it mainly improves is that cable feedthrough 5 bottoms fuse the sheath of cable 4 and each heart yearn by perfusion sealer 7; Cable feedthrough 5 tops are by lock sheet 9 and Cock screw 10 fastening cables 4; Also be provided with O type circle 8 between cable feedthrough 5 and the connector cover 6.
Present embodiment in use, the cable 4 of peelling off one section sheath is passed in the cable feedthrough 5, make the part sheath of cable 4 and the following cavity that heart yearn is positioned at cable feedthrough 5 together, to 5 times cavity perfusions of cable feedthrough sealer 7, after glue 7 to be sealed solidifies, in the upper plenum of cable feedthrough 5, compress cable 4 with lock sheet 9 by screwing Cock screw 10, reach that sealing is reliable, cable is difficult for loosening effect.Adopt O type circle 8 between cable feedthrough 5 and the connector cover 6 again, and tighten together by bolt 3 and bullet pad 2.
