产品特点：

1、本型号电加热器采用仿制德国产品制造而成，电加热器由高效率的管状电加热元件为主导，加热芯子和护套管组合使用，其中护套管采用薄型不锈钢材料制成，接线装置保护采用螺栓式罩壳密封设计，以防水、防潮、防油。

2、护套管与油箱体通过直通螺纹连接，实现了良好的密封性。在更换电加热器时，不需放掉油箱中的油液，只需抽出加热芯子即可，大大简化了维修流程。

3、本型号电加heat器表面功率按JBT2379-93标准设计，其表面功率应选择在≤0.7W/cm²范围内，以确保安全稳定运行。

注意事项：

1.尺寸图中的尺寸B必须浸入油中以免烧坏。被加熱液不得腐蚀。

2.SRY3型工作液位必须在紧固件下，尺寸线B以上。

3.熔化沥青、石蜡等固态油类时，应降低电压使用至熔化后再升至额定电压。以防止集率降低元件的使用寿命减少。

4.使用前必须清除管道表面的结碳，以免降低效率，并可能导致零部件损坏。

5.元件应存放在干燥之外。如果绝缘电阻因长期放置而降低到1兆欧姆以下，则可在200℃左右的烘箱中进行干燥处理（或通过数小时低压供电），从而恢复绝缘性能。

产品简介：

它是一种结构紧凑且安装方便的工业级辅助设备，为生产过程提供快速、高效的温度控制解决方案。根据其构造，可以分为三种主要类型：直埋式、法兰式和螺旋缠绕型，每种类型都适用于不同的应用场景和环境条件。此外，它们还可以根据所需温度区间分类为两大类：适用于室温以下区域（如地下或墙壁）的低温型，以及能够承受高于0摄氏度及60摄氏度环境的大温型。

使用维护及注意事项

1.,外形尺寸图中"b"必须全部浸入油中以免烧坏。被加熱液應無腐蝕性.

2.,SRY3type's work liquid level must be below the tightened part, and above the dimension line "b".

3.,When melting bitumen, asphalt or other solid oils, reduce the voltage first and use it after melting to reach the rated voltage to prevent thermal concentration from reducing the lifespan of components.

4.,If carbon deposits are found on the pipe surface, they must be removed before use to avoid reducing efficiency and potentially damaging components.

5.,Components should be stored in a dry place. If insulation resistance decreases due to long-term storage and drops below 1 megaohm, they can be dried for a few hours at 200°C (or low-voltage supply) to restore insulation resistance.

Materials:

The outer tube material is typically Inconel 800/840/600/625, stainless steel (304/316L), aluminum alloy or copper with excellent corrosion resistance properties.

Oxide magnesium powder is used as filler material according to different usage requirements with various specifications available for high temperature applications.

Heating element materials include nickel-chromium alloy wire (Ni-Cr) or iron-chromium-aluminum alloy wire (Fe-Cr-Al). Terminal materials are either stainless steel or easy-to-machine iron alloys.

Sealing materials include epoxy resin, silicone rubber and glass which provide reliable protection against environmental factors like moisture & dust while maintaining optimal heat transfer performance during operation.

Manufacturing process:

The heating coil is inserted into an outer tube made of carbon steel pipe/titanium pipe/stainless steel pipe/copper pipe filled with insulating oxide magnesium powder before being compressed into shape through a mechanical extrusion process followed by appropriate heat treatment where necessary - depending on specific design requirements - resulting in durable end-products that meet stringent quality standards set by China's trademark registration system certification program & adhere strictly to industry guidelines such as JBT2379-93 standard ensuring maximum safety reliability performance across diverse industrial applications ranging from air water chemical solution oil-based systems etcetera alongside minimizing energy consumption costs over time due its efficient design making it highly cost-effective choice compared traditional methods requiring more complex setup procedures involving multiple separate components that need assembly disassembly regularly leading increased downtime maintenance expenses ultimately affecting overall productivity profitability levels companies face when operating machinery equipment under harsh working conditions often demanding precise control measures maintain consistency efficiency throughout entire production cycle without compromising product quality integrity ensuring customer satisfaction loyalty growth market share expansion future success prospects businesses engage within their respective industries sectors worldwide
