SRY2-1/SRY2-2 Threaded Oil Heater
Threaded installation single-head electric heating tube structure: A hollow bolt with a hexagonal head (for tightening) of varying sizes (determined by the customer) in metric (or imperial) threads is welded to the terminal part of the single-head electric heating tube. It can be divided into two types: hexagonal head facing up and facing down. Application: Widely used for heating various liquid materials, can withstand pressure ≥0.8Mpa. Recommended specifications: 8︿20×60︿1000
Product Features:
1. SRY2-1/SRY2-2 Threaded Tubular Electric Heater, when heating air, the elements should be arranged crosswise and evenly to ensure good heat dissipation and fully heat the flowing air.
2. The wiring part should be placed outside the insulation layer to avoid contact with corrosive, explosive media, and moisture.
3. The lead wires should be able to withstand the temperature of the wiring part and the heating load for a long time. When tightening the wiring screws, avoid excessive force.
4. SRY2-1/SRY2-2 Threaded Tubular Electric Heater, the magnesium oxide powder at the outlet end of the electric heating tube should avoid contamination and moisture ingress at the usage site to prevent leakage accidents.
Instructions:
1) The working voltage must not exceed 1.1 times its rated value, and the casing should be effectively grounded.
2) Dimension "B" in the diagram must be fully immersed in oil (and checked regularly) to avoid burning; the heated oil should be free of corrosive gases.
3) The mounting hole size for this electric heater is φ65mm.
4) This model heater is designed according to the JB2379-78 flowing oil standard, with a surface load of 2-3.8 W/cm².
5) When selecting, the heater size should be determined based on the actual dimensions of the heating medium.
Precautions:
1. Dimension "B" in the outline drawing must be fully immersed in oil to avoid burning the component. The heated oil should be non-corrosive.
2. When melting solid oils such as asphalt and paraffin, reduce the voltage until melted, then increase to rated voltage to prevent heat concentration and reduce component lifespan.
3. If carbon deposits are found on the tube surface, they must be removed before reuse to avoid reduced efficiency or even component damage.
4. The component should be stored in a dry place. If the insulation resistance drops below 1 MΩ due to long-term storage, dry the SRY2/SRY3/SRY4 in an oven at about 200°C for several hours (or apply low voltage to the component for several hours) to restore insulation resistance.
