Detailed Information of HRY4|HRY5|HRY6 Sheathed Electric Heaters:
Product Use:
Used for heating hydraulic and lubricating oil in hydraulic lubrication devices, and can also be used for heating non-corrosive gases or liquids.
Product Features:
1. Adopting the form of multiple U-shaped electric heating elements matched with multiple special-shaped sheaths, it has the characteristics of large heat dissipation area, fast heat transfer, and long service life. It is convenient for replacement and maintenance.
2. Due to the use of multiple U-shaped electric heating elements matched with multiple special-shaped sheaths, if a certain heating element is damaged, only that damaged heating element needs to be replaced without replacing the entire heating source, greatly reducing the subsequent investment of the user.
3. The surface load design can be determined according to customer needs. The standard surface load design is 0.7 watts per square centimeter.
4.The sheathed tubular electric heater can be optionally equipped with liquid expansion thermostat, manual reset, AC contactor and other electrical equipment. If the heater needs temperature adjustment function, the heater only needs to be installed with temperature control equipment. When ordering, add the letter "T" after the model number; if automatic constant temperature function is required, the heater should be equipped with a thermostat and contactor, and when ordering, add the letters "TH" after the model number.
5. Working voltage allowable error: not greater than 1.1 times its rated value. The shell should be effectively grounded.
6. Working environment: relative humidity not greater than 95%, no explosive, flammable, and corrosive gases.
7. Heater material: carbon steel or stainless steel.
8. Maximum working temperature: 200°C.
9. Working pressure: less than 0.6MPa
10. Specifications and overall dimensions: see the table and attached drawings on the next page
Usage, Maintenance, and Precautions:
1. The dimension "B" in the overall dimension drawing must be fully immersed in the oil to avoid burning the components.
2. The heated medium should be non-corrosive.
3. When melting solid oils such as asphalt and paraffin, the voltage should be reduced, and after melting, raise to the rated voltage to prevent excessive heat concentration from reducing the service life of the components.
4. If carbon deposits are found on the surface of the heating tube, they must be completely removed before use to avoid reducing efficiency or even burning out the components.
5. Components should be stored in a dry place. If the insulation resistance drops below 1 megohm after long-term storage, the heating core can be taken out and dried in an oven at about 200°C for several hours (or the component can be powered at low voltage for several hours) to restore the insulation resistance.
