SRY6-6 Sheath-type Electric Heater Content
Specifications and Technical Data
1. Working voltage tolerance: not greater than 1.1 times its rated value, the shell should be effectively grounded.
2. Working environment: relative humidity not greater than 95%, no explosive or corrosive gases.
3. Metal tube material: 10# steel
4. Maximum working temperature: SRY2, SRY3 is 300℃, SRY4 is 100℃
5. Working pressure of SRY2 and SRY4 types is less than 2 kg/cm².
6. Fastener length of SRY3 type is 25 mm.
III. Usage, Maintenance and Precautions
1. Dimension "B" in the outline drawing must be fully immersed in oil to avoid burning the element. The heated oil should be non-corrosive.
2. The working liquid level of SRY3 type must be below the fastener and above the dimension line "B".
3. When melting solid oils such as asphalt and paraffin, use reduced voltage first, then increase to rated voltage after melting to prevent concentrated power from reducing element service life.
4. If carbon deposits are found on the tube surface, they must be completely removed before reuse to avoid reduced efficiency or even burning of the element.
5. The element should be stored in a dry place. If the insulation resistance drops below 1 megohm due to long-term storage, it can be dried in an oven at about 200℃ for several hours (or pass low voltage through the element for several hours) to restore insulation resistance.
