Leader in Motor Aluminum Casing Heaters/Motor Casing Heaters/Aluminum Casing Heaters/Pump Casing Heaters---Changzhou JunTai Machinery Technology Co., Ltd., a high-tech enterprise, one of China's top 10 induction heating equipment manufacturers, offering reliable and trustworthy quality products.

I. Pump Casing HeaterApplication: The GJT30 series heater is mainly used for heating various types of metal components such as bearings, gears, gear rings, motor aluminum casings, pistons, connecting rod small ends, wheel hubs, and tires, causing them to expand to meet the needs of interference fit assembly or disassembly.

II. Pump Casing HeaterStructure and Working Principle

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

● Working Principle:

     1. Short-circuit heating: The main unit is a specially structured transformer with a movable yoke for directly passing through bearings or other workpieces to be heated. During operation, when the main unit's power is connected, a short-circuit current is induced in the workpiece (equivalent to a secondary winding), causing it to heat up.

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

III. GJT30Pump Casing HeaterAdvantages:

  ● 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 or gasoline pollution, benefiting environmental improvement and workers' health;

  ● Enhanced Quality: Uniform heating, clean workpiece surface, unchanged hardness, automatic demagnetization in compliance with JB/T6641-2007 standard;

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