Sep 27, 2017

Lubricating oil heater:

Suitable for heating air, oil, water, chemical medium, hot pressing die, melting salt, alkali and low melting point alloy etc

Electric heating tube three - phase method

In the 380-volt three-phase four-wire circuit, the voltage between any two wires is 380 volts, which can form 220 volts between any one line of fire and the zero line. The system can be formed three kinds of power: namely single-phase 220 v power supply, single-phase 380 v power supply, three-phase 380 v power supply, the first home is more, the third class with more factory motor, the second with less, only the ac arc welder is often used single-phase 380 v power supply

Working principle

Use maintenance and precautions

1. The size "B" in the contour map must be fully immersed in the oil to avoid burning the elements. Heating oil should be non-corrosive.

2. The working fluid of SRY3 must be above the fasteners and the dimension line "B".

3. Melt bitumen, paraffin and other solid oils should be reduced by voltage, and then rise to the rated voltage after melting. To prevent the power concentration from reducing the service life of the components.

4. When the surface of the pipe is found to have a carbon, it must be used in addition to avoid reducing efficiency and even burning out elements.

5, components should be stored in dry, if placed because of long-term and reduce insulation resistance less than 1 megohm, can be in around 200 ℃ oven drying several hours (or components of low voltage through several hours), if restoring insulation resistance.


1. Most hot wind circulate in the box, with high thermal efficiency and energy saving.

2. Using forced ventilation, the box has adjustable split air board, and the material is dry and even. Heat source can be used by steam, hot water, electricity, far infrared, wide selection.

3. Small noise and smooth operation. Temperature control, installation and maintenance is convenient.

4. Suitable for wide range, dry all kinds of materials, general drying equipment.

Application scope and purpose:

Range of application

Hot air circulation oven is suitable for heating curing and drying of pharmaceutical, chemical, food, agricultural and sideline products, water products, light industry, heavy industries and other industries. Such as pharmaceuticals, Chinese medicine, Chinese medicine yinpian, water extract, powder, granule, granule, pill, packing bottle, pigment, dyestuff, dehydration vegetable, dried fruit and melons, banger, plastic resin, electric elements, drying varnish and so on.

Main technical parameters of hot air circulation oven and related description:

1. Heating heat source steam, electricity, far-infrared, and electric vapor, for user selection.

2, the use of temperature, steam heating 50 ~ 140 ℃, up to 150 ℃.

3, electricity, far infrared temperature 50 ~ 300 ℃.

4. Common steam pressure is 0.2-0.8 Mpa (2 ~ 8KG).

5. There are three kinds of materials: carbon steel, aluminum plate and stainless steel.

The strong air circulation system with unique design ensures the stability of the temperature. The temperature control system adopts digital display control temperature, which is intuitive and eye-catching, with a reliability protection device and overtemperature alarm. Special requirements, the introduction of production line can be customized for users.
