In the use of mechanical heating equipment, the installation and fixing of the heating element is a subtle and indispensable process, which can make it more stable to work normally. The lack of this process will cause the heating element to break dead, the work is unstable, and the local bare leakage is easy to become a hidden danger of accidents and so on.
1. The common mold heater does not need to be fixed, and is directly installed in the heating hole for heat transfer.
2 Cartridge heater has several types of common and L-shaped , baffle-type , and threaded type. The L-type cartridge heater element can be directly inserted into the general use environment, and it does not need special fixing according to the installation instructions. The baffle type heating element can be used directly or welded and fixed on the basis of the baffle. The installation of threaded cartridge heater is to screw the heating pipe thread in the part that needs to be fixed, the sealing of strict requirements can also be welded on the original basis.
U-shaped heating element, flange type heating element, fin heating element and U-shaped heating element is normally assembled with fasteners, usually using fasteners directly installed, if no fasteners, using a bracket or welding installation fixed. The flanged heater means that it is installed and fixed in accordance with the way of installing the flange, and the installation of the flange can generally be classified by connection flanges (bolted) and welded flanges. Usually in the case of low pressure or the sealing requirement is not very high, the connection flange can be fixed by the metal gasket through the original or post-processing several bolt holes. In the case of high pressure or low pressure large diameter flanges can be welded flanges, which are installed and fixed by welding. It can be said that the basic double-head heating pipe needs to be installed, and fasteners can be installed.
