The electric heating rod(cartridge heater) has passed the explosion-proof grade identification, the explosion-proof mark ExdeIIBT3~T4 or ExdIIBT4, and has been approved by the China Classification Society. Explosion-proof certificate number: CE061342U and CE041455. Characteristics of electric heating rod Characteristics of electric heating rod The electric heating rod has a solid structure, high bending strength, compactness, sealing, explosion-proof, and is suitable for heating and heat preservation of various types of oil tanks for storing petroleum and its products. 2. The electric heating rod has uniform heating, low surface heat load and long service life. No reactive power loss, high thermal efficiency, easy operation and maintenance, no need for maintenance. The electric heating rod can be replaced and repaired without removing the medium inside the container. The explosion-proof electric heating rod (hereinafter referred to as electric heating rod) is a rod type heater which uses a mineral insulated heating cable as a heating element, and is used for adding and heating heat of a liquid medium for tank storage, and is suitable for heating various liquid mediums other than gasoline. It can be used in petrochemical refining and oil recovery fine metallurgy glass electric medicine health food and other fields. The DBRL series electric heating rods do not have to be perforated in the tank, and can be installed using a manhole.
1. Electric heating element products are generally made of high-quality imported stainless steel pipe, imported high-temperature magnesium oxide powder, high-quality electric heating wire and other materials to make heating components, and other structural parts made of stainless steel, with excellent overall performance and long life. Easy to repair features.
2. Evenly distribute the high-temperature resistance wire in the stainless steel seamless tube, and fill the void portion with the crystalline magnesium oxide powder with good thermal conductivity and insulation performance. The structure is not only advanced, but also has high thermal efficiency and uniform heat generation. When there is current in the high-temperature resistance wire, The generated heat is diffused to the surface of the metal tube by the magnesium oxide powder, and then transferred to the heated member or the air to achieve the purpose of heating.
3. Carbon fiber infrared electric heating tube, the carbon fiber heating element is a non-metallic material containing more than 95% carbon, the carbon fiber material is pure black body, has rapid temperature rise, no instantaneous starting current, high infrared radiation efficiency, wavelength range Wide coverage, long service life, drying and drying efficiency is more than 30% higher than ordinary electric heating tube.
The controller is designed with two parts: computer automatic control and strong electric hand operation to ensure the startability of the system. In order to prevent the system from stopping any operation caused by any minor faults in the control system and its primary instrument, the control system can keep the system running as much as possible while ensuring safety. When the computer automatic control and instrumentation fail, it can be manually operated. The system continues to run.
Product use precautions.
1. Although the electric heater is equipped with a thermal protector, the power can be automatically cut off, but only when there is wind in the air duct, it is necessary to avoid accidents caused by the heater. Before heating, check that all relevant components are in a normal state, and ensure that the electric heater can be put into use after the fan is in normal operation, thus eliminating the possibility of ultra-high temperature without air drying. It is recommended to control with the fan.
2. The power supply voltage and the electric heater voltage must be equal. The main power supply of the electric heater should be provided separately. The electric heater must be properly connected to the control circuit before it can be put into service.
3. Although the electric heater has various protection devices, all the terminals should be inspected before use. Grounding measures should be taken to ensure safety.
4. The filter should be installed at the air inlet end of the electric heater, and the filter should be cleaned regularly to prevent various foreign objects from entering the damaged electric heating tube or affecting the life and heat dissipation performance of the heating tube.
5. When installing, the terminal should be kept at least one meter away for easy maintenance and maintenance.
