As the lead wire of the refrigeration motor, it is the part where the refrigeration motor is connected to the power supply. Therefore, during the insulation process of the motor, the lead wire is not allowed to leak impregnated varnish, because once the impregnated varnish enters the lead wire When the impregnating paint of the motor is dried, it will cause the lead-out part to harden, thus bringing the following adverse effects to the motor: the lead-in wire becomes hard, making installation difficult or impossible to complete normal installation at all; hardened lead-in After the wiring is forcibly bent, it is very easy to cause the internal conductor of the lead wire to break; the hardened lead wire will also cause damage to the outer insulation of the lead wire during subsequent operations, resulting in a complete loss of insulation performance

Embodiment 1
[0021] as attached figure 1 As shown, the lead-out wire of the refrigeration motor to be sealed in this embodiment is an enameled wire 3, which is used to connect the refrigeration motor 1 and the power supply 2, and the enameled wire 3 is a main type of winding wire, which is composed of a conductor and an insulating layer. After the thread is annealed and softened, it is painted and baked several times. Of course, the lead-out wires of the refrigeration motor to be sealed can also be glass fiber-wrapped wires. For large and medium-sized winding wires, when the heat resistance level is high and the mechanical strength is high, it is more appropriate to use glass fiber-wrapped wires as the winding wires.
[0022] The sealing method in the present embodiment is carried out as follows:
[0023] 1) Apply 704 silicone rubber 4 on the enameled wire 3, and the coating range must completely cover the enameled wire 3. 704 silicone rubber 4 is a one-component room temperature vulcaniz...

The invention discloses a sealing method for preventing impregnating varnish from passing through a joint of a refrigeration motor outgoing line and a motor winding. The method comprises the following steps of: 1) coating a sealgum layer on the refrigeration motor outgoing line to be sealed; 2) sleeving a heat shrinkable tube on the refrigeration motor outgoing line which is to be sealed and is coated with the sealgum layer; and 3) heating the heat shrinkable tube to make the heat shrinkable tube radially shrink until the inner wall of the heat shrinkable tube is closely pressed on the sealgum layer coated on the refrigeration motor outgoing line to be sealed. The invention solves the problems in the prior art and provides the sealing method for preventing the motor outgoing line from hardening with varnish and influencing or breaking the motor.
Description
technical field [0001] The invention relates to a method for sealing a lead wire of a refrigeration motor. Background technique [0002] Dip varnishes are divided into two categories: solvent-based varnishes and solvent-free varnishes. They are mainly used to impregnate coils and insulating parts of motors and electrical appliances to fill their gaps and micropores. Flatten the paint film and bond the coil into a solid whole to improve the performance of moisture resistance, heat conduction, dielectric strength and mechanical strength of the insulation structure. This process is called insulation treatment process. As the lead wire of the refrigeration motor, it is the part where the refrigeration motor is connected to the power supply. Therefore, during the insulation process of the motor, the lead wire is not allowed to leak impregnated varnish, because once the impregnated varnish enters the lead wire When the impregnating paint of the motor is dried, it will cause the l...
