Abstract
The utility model relates to a sealing device of a submersible pump. The sealing device comprises a cable protective jacket, a press protective jacket, a copper bush and a cable, wherein one end of the cable is sleeved with the cable protective jacket, the cable is sleeved with the press protective jacket closely attached to the cable protective jacket, the press protective jacket is sleeved with the copper bush, and threads are arranged on the outer side of the copper bush. According to the sealing device, traditional surface contact sealing is changed into body contact sealing, through thread compression, a seal body produce micro deformation axially, and a whole sealing cavity is filled with plastic rubber, so that the sealing performance of an outgoing part is increased, the service life of products is prolonged, and the reliability of the products is increased.
Description
Technical field
The utility model relates to water pump and manufactures field, particularly relates to a kind of submersible pump sealing device.
Background technique
Sealability directly affects the q&r of submersible pump product, and wherein the sealing of the power line of submersible pump outlet position is one of key.The power line sealing of existing product is all to adopt two plane contact, and by a structure that pressing plate is fixing, this structure is because surface of contact is little, and the poor rigidity of pressing plate, easily distortion, affect sealing.Especially when submersible pump moves in deep-well, under the environment that external pressure strengthens, just easily cause leakage, motor is damaged, water pump cannot be worked.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of submersible pump sealing device, for improving the sealing of submersible pump, increases its working life and reliability.
The utility model solves the technological scheme that its technical problem adopts: a kind of submersible pump sealing device is provided, comprise wire bushing, compress sheath, copper sheathing and cable, described wire bushing is socketed on the end of a thread of cable, described compression sheath is socketed on cable, and be close to wire bushing, described copper sheathing is socketed in and compresses on sheath, and described copper sheathing disposed outside has screw thread.
It is stepped that described wire bushing is circular cone, and its top is arranged side by side with several circular holes, and the electric wire in described cable passes from circular hole.
Described press sheath to be cylinder stepped, its top is close to copper sheathing inside.
Described wire bushing and Seal cage fit tightly.
Described copper sheathing is threaded with the opening of Seal cage, and by compressing sheath, wire bushing is compressed.
Beneficial effect
The utility model relates to a kind of submersible pump sealing device, make traditional face contact sealing into body contact sealing, and compress by screw thread, make seal axially produce small distortion, make plastic rubber fill up whole Seal cage, thereby increase the sealing of wire outlet part, improved working life and the reliability of product.
