As an electric boiler heating body manufacturer, today Xiaobian will come and talk to you about how to replace the electric boiler heating body.
Electric heating boiler is mainly composed of boiler body, electric control box and control system. The boiler body is composed of a drum and a heating tube. The electric heat pipe of the boiler is the heart of the electric boiler, and the electric heating tube is the core component of the electric heating boiler, which directly determines the service life of the boiler, and its performance is directly related to the performance of the electric boiler.
The electric heat pipe is generally selected in the form of a tube, which is composed of a metal stainless steel tube, a nickel-chromium alloy heating wire, a leading rod, a connecting base and a magnesium oxide filler. Under normal circumstances, the service life of the electric heating tube is 10,000-30,000 hours. The service life of the electric heating tube mainly depends on the material of the electric heating tube, the surface heat load and the user's operation management level. The electric heating tube is a nickel-chromium stainless steel pipe with a surface heat load of 6-9W/cm2. In addition, the rated electrical power of the electric heat pipe is also a very important performance indicator. Under rated working conditions, according to the national standard, the electric power deviation should not be greater than 5%.
So what are the steps for the replacement of the electric boiler heater? When replacing the heating tube, there are two parts, the first is to take out: first cut off the power supply cabinet, master which heating tube is the replacement part according to the prompts of the control cabinet in advance, and then open the front cooling window, loosen the screws on the heating tube flange that need to be replaced, separate it from the power cord, and carefully remove the old heating tube.
