Features of explosion-proof oil filter system

Explosion-proof oil filter is a kind of oil filtration equipment specially used in flammable and explosive environments. It has special design and safety performance to ensure safe operation in hazardous environments. The following are the main features of explosion-proof oil filter:

1. Explosion-proof design

- Explosion-proof motor: Use motors that meet explosion-proof standards (such as Ex d IIB T4 or Ex d IIC T4) to prevent sparks from causing explosions when the motor is running.

- Explosion-proof electrical components: All electrical components (such as switches, controllers, sensors, etc.) meet explosion-proof requirements.

- Explosion-proof housing: The housing of the equipment is made of explosion-proof materials, which can withstand internal explosion pressure and prevent flame propagation.

2. Safety protection function

- Overload protection: The motor is equipped with an overload protection device to prevent the equipment from being damaged due to overload.

- Temperature protection: Built-in temperature sensor, automatically shut down when the equipment temperature is too high.

- Pressure protection: Equipped with a pressure sensor, automatically alarm or shut down when the system pressure is abnormal.

3. Applicable environment

- Inflammable and explosive places: such as hazardous environments such as petrochemical, coal mines, natural gas, and oil depots.

- High humidity and high dust environment: The equipment has good sealing and protection level (usually IP54 or higher).

4. High efficiency filtration performance

- Multi-stage filtration: A multi-stage filtration system (such as coarse filtration, fine filtration, adsorption filtration) is used to ensure the cleanliness of the oil.

- High filtration accuracy: The filtration accuracy can reach 1-5 microns (μm), meeting the requirements of high-precision hydraulic systems or lubrication systems.

- Water removal function: Some explosion-proof oil filters are equipped with vacuum dehydration or coalescence dehydration devices, which can effectively remove moisture from the oil.

5. Structural design

- Compact design: The equipment has a compact structure and is easy to move and install.

- Corrosion-resistant materials: The parts in contact with the oil are made of stainless steel or corrosion-resistant materials to extend the life of the equipment.

- Mobile design: Some models are equipped with casters or carts for easy movement in the factory or on site.

6. Operation and maintenance

- Automatic control: equipped with PLC control system to achieve automatic operation and monitoring.

- Easy maintenance: easy to ｒｅｐｌａｃｅ the filter element, and the equipment operation status can be monitored in real time.

- Low noise design: low operating noise, in line with industrial environment requirements.

7. Compliance with standards

- Explosion-proof certification: in line with international explosion-proof standards (such as ATEX, IECEx) or national standards (such as GB 3836).

- Safety certification: passed ISO, CE and other quality and safety certifications.

8. Typical applications

- Petrochemical industry: filtering transformer oil, lubricating oil, hydraulic oil, etc.

- Coal mining industry: filtering lubricating oil or hydraulic oil of underground equipment.

- Natural gas industry: filtering compressor oil or gas turbine lubricating oil.

- Aerospace: filtering aviation fuel or hydraulic oil.

9. Selection considerations

- Explosion-proof level: ｓｅｌｅｃｔ the appropriate explosion-proof level (such as IIA, IIB, IIC) according to the use environment.

- Filter media: ｓｅｌｅｃｔ the appropriate filter element material according to the type of oil (such as lubricating oil, hydraulic oil, fuel oil).

- Flow rate and precision: ｓｅｌｅｃｔ the appropriate flow rate and filtration precision according to system requirements.

The explosion-proof oil filter can operate safely and efficiently in hazardous environments through its special design and safety performance. It is an ideal choice for industries such as petrochemicals and coal mining.
