The GJT30H-DJ motor aluminum shell heater is suitable for rapid heating of motor aluminum shells/submersible pump shells/aluminum machine shells, etc.

Leader in motor aluminum shell heaters/motor shell heaters/aluminum machine shell heaters/pump shell heaters---Changzhou Juntai Machinery Technology Co., Ltd., a high-tech enterprise, one of China's top 10 induction heating equipment companies, offering reliable and trustworthy quality products.

I. Purpose of the motor aluminum shell heater: The GJT30 motor aluminum shell heater is mainly used for heating motor aluminum shells (cast aluminum, drawn aluminum) metal parts to cause expansion, meeting the needs of interference fit assembly.

II. Structure and working principle of the motor aluminum shell heater

● Structure of the motor aluminum shell heater: The GJT30 series heater consists of a dry self-cooling power frequency induction heating device (hereinafter referred to as the main unit) and control equipment.

● Working principle of the motor aluminum shell heater:

1. Short-circuit heating: The main unit is a specially structured transformer, with a movable yoke used to directly sleeve bearings or other workpieces to be heated. During operation, when the main unit power is connected, the workpiece (equivalent to the secondary winding) induces a short-circuit current and is heated.

2. Eddy current heating: The heated workpiece and the main unit's iron core form a closed magnetic circuit. During operation, the magnetic flux lines from the main unit generate eddy currents in the workpiece, resulting in rapid heating.

III. Advantages of the GJT30 motor aluminum shell heater:

● Improved efficiency: Work efficiency increased by more than 4 times, reducing operators by 80%;

● Cost reduction: Saves over 70% in electricity, 100% in oil, and reduces workshop space by more than 60%;

● Environmental protection: No oil pollution in the air, beneficial for environmental improvement and workers' health;

● Enhanced quality: Uniform heating, clean workpiece surface, unchanged hardness, automatic demagnetization in compliance with relevant standards;

● Reliable operation: Easy and safe to operate, extremely low equipment failure rate, main unit under warranty for 18 months, insulation up to class B;
