The pipeline electric heater is a new type of equipment specially developed for heating gas fluids. The equipment consists of two parts: the pipeline body and the control system. The heating element adopts stainless steel seamless tube as the protective sleeve, high temperature resistance alloy wire, crystalline magnesium oxide powder, formed by the compression process, so that the service life of the electric heating element can be guaranteed. The control part adopts high-precision digital display temperature controller and relay to form an adjustable temperature measurement and constant temperature system to ensure the normal operation of the electric heater.
The most important core part of the heating tube is the work of the heating wire. The quality of the heating wire determines the quality of the heating tube. The research on the heating wire is to study the resistance of the heating wire. The resistance determines the power of the heating tube. The resistance value of the electric heating tube is fixed, and when different working voltages are connected, the effect of different electric heating tube power appears, and the same is true for the heating effect. Generally, the smaller the resistance, the larger the wire diameter of the resistance wire. When the voltage is fixed, the current passed by the resistance wire will be larger. When the current passed exceeds the load of the resistance wire, it is prone to breakage and damage. The data indicates the heating tube The resistance is not as small as possible. The appropriate resistance wire should be selected according to the actual situation of the electric heating tube and to ensure normal use. The items that need to be maintained during the daily use of the pipeline heater are: 1. When the heating medium is liquid or water, during use, please open the water valve first, and then turn on the electric heating after the pipeline heater manufacturer's water supply is normal. The heating tube can not be heated in an empty state, otherwise the side is easily damaged. 2. When the working medium is ordinary water, the heater needs to be taken out after two months of use to clean up the scale on the surface of the heating tube. 3. The pipeline electric heater, especially the control part, is a precision instrument. It must be handled with care during transportation, and impact and bumping are strictly prohibited. The cylinder part should be hoisted reasonably to avoid deformation and damage to the internal heating elements. The pipeline electric heater and control cabinet are placed in the warehouse, and it is strictly forbidden to get wet.
The heating tube is a metal tube with a resistance wire, which is the same as an electric furnace wire. The heating principle is that the current passes through the resistor to generate heat. It has excellent performance such as long service life, high electrothermal conversion efficiency, far infrared radiation, health and environmental protection. The heating tube is more suitable for anti-fouling heating places, and is the best choice for anti-rust and anti-fouling. It is electroplating, electrolysis, degreasing, pickling, electroless nickel and phosphorus plating, anodizing, aluminum plating, smelting, chemical industry, medicine, food and other corrosive liquid phase heating, condensation, evaporation, concentration, etc. It is the best choice for anti-rust and anti-scaling! At the same time, it can greatly reduce acid consumption, energy consumption, waste liquid generation and improve the working environment, which is conducive to environmental protection.
