| The temperature control principle of the electric heating rod DJKL-12 for steam turbine bolts involves multiple aspects such as electric heating alloy materials, current regulation, automatic control and temperature sensors. The temperature control principle of the electric heating rod for steam turbine bolts is mainly to control the temperature of the heating rod by adjusting the current. Specifically, when the heating rod is working, its resistance will increase with the increase of temperature, so the current passing through the heating rod will also decrease, thereby controlling the temperature of the heating rod. The way to adjust the current size can be achieved by manually adjusting the control cabinet system. |
| Technical parameters: The rated working voltage of the electric heater is 220±20V. DC 100V, low voltage 50V; The center line straightness of the electric heater with an insertion length of less than 1m is not greater than Ø0.3mm; the center line straightness of the insertion length of 1-2m is not greater than Ø0.4mm; The diameter deviation of the insertion part is -0.20mm/-0.50mm; The length deviation of the insertion part is ±5mm, the heating length deviation is ±5mm, and the bottom cold end length is 25-30mm; The electric heater is required to heat evenly during use, and local overheating is not allowed. |
| Product Features: Efficient and high-temperature resistant |
| Applications: Specially used for heating hollow bolts in steam turbines and large machinery during installation and maintenance to meet the requirements of fastening and dismantling |
