Why Need to Maintain a Cartridge Heater
The heating coil is a mechanical load. It is composed of a strand of nichrome wire that is wound around a ceramic core. The number of spirals per inch depends on the watt density. An alternating current source, which is either two-phase or three-phase, is inserted into the heating coil. The alternating current flows through the coiled nichrome wire, heating it. The lead has a connector for connecting the lead and heater to the power supply.
The heating coil has several different components. The most important component of the cartridge heater is the sheath. This outer layer makes direct contact with the liquid or material. Because the sheath needs to protect the internal components, it must be able to withstand high temperatures. Stainless steel is commonly used for sheaths. In addition to this, a cartridge heater must be able to withstand extreme vibration. If the heating coil is not designed to withstand these kinds of pressure, it will not be able to heat up.
