Performance characteristics of SRY2 and SRY3 tubular electric heaters

Performance characteristics of SRY2 and SRY3 tubular electric heaters
SRY2, SRY3 tubular electric heaters are used for heating oil in open or closed oil tanks. SRY4 tubular electric heating unit is used to heat flowing or circulating oil. This type of heater has high surface load and is only suitable for heating. Used in good oils.
Tubular electric heater specifications and technical parameters:
1. Specifications and dimensions: see Table 1 and Figure 1-2
2. Operating voltage tolerance: no more than 1.1 times its rated value. The enclosure should be effectively grounded.
3. Working environment: the relative humidity is not more than 95%, no explosive, flammable and corrosive gases.
4. Metal pipe material: No. 10 steel.
5.zui high working temperature: 100 °C.
6. The working pressure of SRY2 type and SRY4 type is less than 0.6MPa.
7. Tank opening: ≥ φ65.
Maintenance and precautions:
1. Dimensions "B" in the external dimensions must be immersed in the oil to avoid burning the components. The heated oil should be non-corrosive.
2. When melting solid oil such as asphalt and paraffin, the voltage should be reduced, and then increased to the rated voltage after melting. To prevent heat concentration and reduce component life.
3. When there is carbon deposit on the surface of the pipe, it must be removed before use to avoid reducing the efficiency and even burning the components.
4. The components should be stored in a dry place. If the insulation resistance drops to less than 1 megohm due to long-term placement, it can be dried in an oven at about 200 °C for several hours (or the components are low-voltage for several hours) to restore insulation. resistance.
structure
The wiring device and the heating structure are improved, and three heating tubes are used as a group, which effectively reduces the surface load of the heater and can directly replace the SRY2-SRY4 type heater.
1. The electric heater is used for hydraulic pressure, the lubricating device heats the hydraulic oil and the lubricating oil, and can also be used for heating non-corrosive gas or liquid.
2. The electric heater is composed of a heating core and a sheath tube. The heating core uses a tubular electric heating element as a heat source, and the sheath tube is made of thin stainless steel, which has a large heat dissipation area, fast heat transfer, and a part of the terminal device. It is a common type (using an iron-drawn cup-type cover) and a special type (sealed by a bolt-type flame-proof device cover), and the special type has the requirements of the explosion-proof mark dIICT4.
3. The electric heater and the fuel tank body are flanged, and the sheath separates the heating core from the heated oil. When the electric heater is repaired, the oil in the oil tank does not need to be drained, and only the heating core needs to be taken out. Replace with a new heating core for easy maintenance.
4. The contact area between the sheath and the hot refueling solution should be considered in the design so that the oil will not be partially carbonized due to the excessive heating temperature. This type of heater is only suitable for the heat transfer oil or the oil and medium with better heating effect. Use for heating.
