Tubular Electric Heater JGY4-380V6KW Price Performance and Use
Flange Heating Tube is composed of multiple heating tubes welded onto a flange for centralized heating. It is mainly used for heating in open or closed solution tanks and circulation systems.
Tubular Electric Heater JGY4-380V6KW Price Precautions:
1. The element is allowed to work under the following conditions:
A. The relative humidity of the air is not more than 95%, and there is no explosive or corrosive gas. (Except for explosion-proof heaters)
B. The working voltage should not exceed 1.1 times the rated value, and the shell should be effectively grounded.
C. Insulation resistance ≥1MΩ; Dielectric strength: 2KV/1min.
2. The electric heating tube should be properly positioned and fixed. The effective heating area must be fully immersed in liquid or solid metal. Dry burning is strictly prohibited. If scale or carbon deposits are found on the tube surface, they should be cleaned promptly before reuse to avoid affecting heat dissipation and shortening service life.
3. When heating fusible metals or solid nitrates, alkalis, asphalt, paraffin, etc., first reduce the operating voltage, and only after the medium melts can it be raised to the rated voltage.
4. When heating air, the elements should be arranged crosswise and evenly to ensure good heat dissipation conditions, allowing the flowing air to be fully heated.
5. When heating nitrates, safety measures should be considered to prevent explosion accidents.
6. The wiring part should be placed outside the insulation layer to avoid contact with corrosive, explosive media, or moisture. 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.
7. The element should be stored in a dry place. If the insulation resistance is lower than 1MΩ due to long-term storage, it can be dried in an oven at about 200°C, or heated by reducing voltage until the insulation resistance is restored.
8. The magnesium oxide powder at the outlet end of the electric heating tube should be protected from pollutants and moisture ingress at the use site to prevent leakage accidents.
9. Non-operating personnel should not operate.
Features:
This electric heater consists of a heating core and a protective tube. The heating core uses a tubular electric heating element as the heat source, and the protective tube is made of carbon steel or stainless steel. It has a large heat dissipation area and fast heat transfer. The terminal device part is divided into a common type using an iron stretched cup-shaped shell, and a special type using a bolted explosion-proof device shell seal. It meets the requirements of the explosion-proof mark dⅡBT4 and protection level IP54 series standards.
The electric heater is connected to the oil tank body by a flange. The protective tube isolates the heating core from the heated oil. When replacing the electric heater, it is not necessary to drain the oil from the tank; only the heating core needs to be extracted and replaced with a new one, making maintenance convenient.
The protective tube has a large contact area with the heated oil, so the oil will not carbonize due to local high temperature. It has a long service life and is safe and reliable.
Introduction:
The electric heating tube, also known as heating tube or heating pipe, is scientifically called a tubular electric heating element. It consists of a coiled heating wire (resistance wire) placed inside a metal tube.
It has the characteristics of simple structure, high mechanical strength, high thermal efficiency, safety and reliability, easy installation, and long service life. It is widely used in various saltpeter tanks, water tanks, oil tanks, acid and alkali tanks, fusible metal melting furnaces, air heating furnaces, drying ovens, drying boxes, hot press molds, and other equipment.
The electric heating tube is an electrical component specifically designed to convert electrical energy into heat energy. Due to its low price, convenient use, easy installation, and no pollution, it is widely used in various heating applications.
