Product Description

Product Description

 

This bolt heating rod DJ-21 adopts three types of protective sleeve designs: straight, semi-soft, and fully soft, to meet the use requirements in different scenarios. The straight protective sleeve is suitable for occasions with high requirements for straightness, while the semi-soft and fully soft protective sleeves can better protect the heating element in complex environments.

 

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
