1. Early detection of equipment failure

Petrochemical production involves a large number of equipment and pipeline systems, and the normal operation of these equipment is crucial for the stability of production. Traditional equipment inspection methods often struggle to detect potential faults in a timely manner. The infrared thermal imaging function of the large walnut explosion-proof handheld terminal can easily meet this challenge.


Through infrared thermal imaging technology, workers can quickly scan the surface temperature distribution of equipment and pipes. Once an abnormal increase in local temperature is detected, it may be an early sign of a fault inside the equipment, such as worn bearings, loose electrical joints, leaking pipes, etc. For example, in a refinery reactor, if infrared thermal imaging of a certain area shows a significantly higher temperature than the surrounding area, it may indicate heat build-up in that area, indicating a possible failure of internal mechanical components or abnormal chemical reactions. Timely detection and treatment of these problems can avoid further expansion of equipment failures, reduce downtime, reduce maintenance costs, and ensure production continuity.

 

2. Pipeline leakage monitoring

Pipeline systems are an important part of petrochemical production, and once a leak occurs, it will not only cause material waste, but also cause serious safety accidents. The infrared thermal imaging capabilities of the Big Walnut Explosion-proof Handheld Terminal offer unique advantages in pipeline leak monitoring.


When a pipeline leaks, the leaking material will take away heat or exchange heat with the environment, resulting in abnormal changes in pipe surface temperature. Infrared thermal imaging technology can keenly capture these subtle temperature differences, allowing for quick location of leaks even at long distances or in complex environments. For example, in the long-distance oil pipeline inspection, the staff uses the large walnut explosion-proof handheld terminal to scan along the pipeline, and once the temperature abnormality in a certain area is found, it can further investigate whether there is a leak in the area. This fast and accurate leak monitoring method greatly improves the safety of the pipeline system.

 

3. Safety testing of electrical systems

The electrical system of petrochemical enterprises is complex and important, and electrical faults can cause serious accidents such as fires and explosions. The infrared thermal imaging function of the large walnut explosion-proof handheld terminal can conduct comprehensive safety inspection of electrical equipment.


Electrical equipment generates heat during operation, and the heating of different parts reflects the operating status of the equipment. Through infrared thermal imaging technology, staff can intuitively observe the temperature distribution of electrical cabinets, wires and cables, and other equipment. For example, if an electrical connector is found to be too hot, it may be due to poor contact that increases resistance and generates too much heat. Timely detection and treatment of these electrical hazards can effectively prevent the occurrence of electrical fires and ensure the safety of power supply for enterprises.

 

4. Storage tank status monitoring

Tanks in petrochemical enterprises store large quantities of flammable and explosive liquids or gases, and condition monitoring of storage tanks is crucial. The infrared thermal imaging function of the large walnut explosion-proof handheld terminal can monitor the tank surface temperature of the storage tank.


Under normal circumstances, the temperature distribution on the surface of the tank is relatively uniform. If an abnormal increase in local temperature is found, it may mean that the tank is corroded, the insulation layer is damaged, or the internal medium is abnormal. For example, localized corrosion of the tank can lead to faster heat transfer, which increases the temperature of the area. Through real-time monitoring of the surface temperature of the tank, staff can detect these problems in time and take corresponding measures to prevent safety accidents such as leaks and explosions in the tank.

 

5. Personnel search and rescue and emergency response

In petrochemical production sites, rapid personnel search and rescue and emergency response are crucial in the event of an accident. The infrared thermal imaging function of the large walnut explosion-proof handheld terminal has unique advantages in harsh environments such as darkness and smoke.


After fires, explosions and other accidents, the scene is often filled with smoke and darkness, and traditional search and rescue methods are difficult to work. Infrared thermal imaging technology can quickly locate the location of trapped people by detecting infrared radiation from the human body. Rescuers can quickly formulate rescue plans based on infrared thermal imaging images to improve rescue efficiency and reduce casualties.

 

The infrared thermal imaging technology of the large walnut explosion-proof handheld terminal has a wide application prospect and important role in the petrochemical field. It can not only realize early detection of equipment failures, pipeline leakage monitoring, electrical system safety detection, tank status monitoring and other functions, but also play a key role in personnel search and rescue and emergency response.
