Description
The heating principle of cartridge heater is that the current through the internal resistance wire , in the case of fixed voltage, the greater the resistance, the smaller the power; The lower the resistance, the higher the power. Is it possible to use small resistance wire to save more cost and improve the thermal efficiency? The answer is no, usually the resistance, the greater the resistance wire of the wire diameter is smaller, a fixed voltage, the greater the resistance wire by current, when more current through the load resistance wire is easy to break and damage, so the resistance is not the bigger the better, should be in accordance with the actual situation and ensure the normal use of choosing appropriate resistance wire.
External connection lead wire cartridge heater is a tube-shaped, industrial heating element that can be inserted into drilled holes.Fast heat cartridge heater provides localized and precise heating and are commonly used in the heating process industry. Typically, Industrial cartridge heater is used to heat a metal block from the inside and can be custom manufactured to a specific watt density based on the requirements of the application.
External Connection Lead Wire Cartridge Heater mainly adopts conventional straight rod single head electric heating tube. Industrial cartridge heater is an electric heating element which makes the mold temperature rise by drilling a hole in the mold and embedding the electric heating tube into the mold hole of mustard bag sealing machine.
Look from the outside, the most obvious feature of the cartridge heater is the small size, but the small size has never affected the reduction of its own power, but the surface load is high.If the cartridge heater element used in the mold hole heating, to tell the truth, the life is not as good as theoretically thought.It has excellent insulation performance, especially in cold state can maintain good insulation performance.It has good operability. When the heating cartridge is used, even if multiple ones are used, they will not interfere with each other, and it is easy to complete wiring in the box.
