The bolt heating rod DJ27.5 is an indispensable device in the process of disassembling and assembling the bolts of the steam turbine. It uses the principle of thermal expansion and contraction to help easily disassemble and install the bolts. By precisely controlling the heating time and temperature, it is essential to ensure that the bolts can be correctly installed in the valve cover, which is essential for the normal operation of the steam turbine. |
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 |
