Abstract

This invention provides a plastic sealant for AC permanent magnetic submersible motor, its sealing process and application. The plastic sealant is composed of: epoxy resin, diluent, curing agent, and silicon micropowder. The process comprises: (1) preparing the plastic sealant; (2) placing the motor stator in the stator sealing mold, locating, and placing the rotor in the rotor sealing mold; (3) sealing; (4) curing. This invention can be used for sealing AC permanent magnetic submersible motor, permanent magnetic wind power generator, electrical appliance, capacitor, transformer and inducer. This invention can largely shorten the sealing time, and can improve the sealing efficiency of diving motor. The plastic sealant has such advantages as low viscosity, smooth pouring, simple process, high product smoothness, good heat conductivity, good insulation, good waterproof property, no pollution during production and usage, and no toxicity to human bodies, thus is suitable for mass production.

Description

technical field

[0001] The invention relates to a motor plastic packaging technology, in particular to a plastic packaging material for an AC permanent magnet submersible motor and its plastic packaging process and application. Background technique

[0002] Existing submersible motors are all AC asynchronous motors, usually adopting a dry or wet waterproof structure. Due to the complex waterproof structure and large loss of mechanical seal, the submersible motor has large volume, low efficiency, and poor reliability of waterproof insulation. Especially for oil-immersed AC asynchronous submersible motors, once the mechanical seal is damaged, the protective oil inside the seal will directly leak out of the submersible. Outside the motor, causing water pollution.

[0003] The existing patent (Patent No. 01108064.7) discloses a plastic sealing material for a plastic-encapsulated submersible motor and its plastic sealing process, which can effectively avo...
