Component - 220V/200W stainless steel resistor 1 inchFilter element diameter: 8mm, filter element length: 23cm, installation type: threadTubular electric heating elements are composed of metal tubes, spiral resistance wires, and crystalline magnesium oxide powder with good thermal conductivity and insulation. Products that can heat the system have simple structure, high thermal efficiency, good mechanical strength, and good adaptability to harsh environments. It can be used for heating various liquids and acid-base salts, and is also suitable for heating and melting metals with low melting points (lead, zinc, tin, babbitt alloy)1. The components are allowed to work under the following conditions:(1) The relative humidity of the air is not greater than 95%;(2) The working voltage should not be greater than 1.1 times the rated value, and the shell should be effectively grounded.2. When the heating medium is liquid, the effective length of the element (H1 or H2) must be completely immersed in the liquid. The heating part of the element should be at a certain distance from the container wall, generally 50-60mm or more.3. Components that heat liquids must not be used to heat gases or solid objects.4. If scale or carbon is found on the surface of the liquid heating element, it should be cleaned before use to avoid affecting the service life of the element and reducing thermal efficiency.5. When heating when smelting light metals or nitrates, alkali, asphalt, paraffin, etc., which are in solid state, the voltage should be reduced and started until the solid heating medium is completely melted before the voltage can be raised to the rated voltage.6. Safety measures should be taken into consideration when heating nitrate salt to prevent explosion accidents.7. The component wiring part should be placed in the insulation layer and outside the heating room, and avoid contact with corrosive and explosive gases. The outlet end must be kept dry and clean to avoid flashover or short circuit. Do not use excessive force when wiring.8. A small amount of paste may overflow from the end of the component. This is the sealing material and does not affect use. Just wipe the overflow clean after the power is turned off.9. Components should be stored in a room with good air circulation, relative humidity not greater than 85%, and no corrosive gases.10. After the component has been used for a period of time and has not been used for a long time and has become damp, and its cold insulation resistance is lower than 1 megohm, the component can be baked in a drying oven with a temperature of about 200 degrees, or the voltage can be reduced and heated directly by electricity to remove moisture. , until it returns to normal.
