If you want the explosion-proof camera to work better, don't ignore its correct installation!
1. The import of explosion-proof cameras must be sealed with rubber sealing rings, and other methods such as filling sealing mud, asbestos, etc. are prohibited; It is prohibited to fill any substance in the cavity. Impact on explosion-proof performance; It is prohibited to use sealing rings and their matching at the inlet for easy connection. Discard the compression nut, and after combining multiple conductors, it is prohibited to enter the inlet through a single hole elastic sealing ring. The oil stains on the rubber sealing ring should be cleaned thoroughly to avoid aging and deterioration.
2. It is strictly prohibited to replace the structure, spare parts, and internal wires of explosion-proof cameras at will. It is not allowed to replace or lose fastening bolts at will. When leaving the factory, the excess elastic and metal gaskets of the inlet and outlet wires must be kept sealed, and the nuts must be tightened to ensure the inlet is tightened.
3. It is prohibited to perform on-site maintenance on electrical equipment and wires in hazardous explosion locations, and power transmission and disconnection are prohibited. During a power outage, a warning board stating "Work in progress and shutdown prohibited" should be hung. During major repairs, if the explosion-proof camera is moved to a safe area, the power cables of the equipment should be installed on site. The wire ends should be treated with explosion-proof measures and electricity usage is strictly prohibited.
4. During daily operations and maintenance inspections, it is advisable to avoid explosion-proof camera casings as much as possible and cut off the power when turning them on. If the explosion-proof shell is opened, the explosion-proof surface should be properly protected and not damaged. During maintenance, the explosion-proof surface should be placed facing upwards and should not come into direct contact with the ground and the site. After cleaning, apply phosphating paste or 204 anti rust oil.
5. All explosion-proof cameras should establish equipment records, including equipment installation, debugging, operation, maintenance, explosion-proof, degradation, and scrapping. Various technical data from different periods should be collected, archived, and numbered on the equipment.
For key safety protection areas such as oil depots, gates, and oil storage tanks, when selecting front-end cameras, explosion-proof shielded cameras are generally used, and night auxiliary lighting devices are considered according to monitoring needs, except for the explosion-proof level of the explosion-proof shielded camera pan tilt.
According to the requirements, a combustible gas detection system is also required. When the detection reaches a certain concentration, the camera will monitor it accordingly and trigger an audible and visual alarm.
From the experience of monitoring engineering, in order to have a safe and stable monitoring system, there must be a stable power supply. Due to the unstable power voltage in the city, power outages often occur in the suburbs, and gas stations that operate 24 hours a day are not allowed to have monitoring blind spots.
Each gas station should be designed with an online UPS power supply to meet monitoring needs.
In addition, gas stations equipped with safety systems may have more or less hidden dangers in lightning protection measures. Therefore, gas stations should be equipped with flashers, leads, and grounding devices. Gas stations should be equipped with lightning rods, with vacant surroundings and protruding buildings. There shall be no less than two storage tanks, and the storage tanks, pipelines, and other metal accessories shall be electrically connected and grounded. When thunderstorms occur, oil unloading work should be stopped and grounded protection should be implemented for oil tankers parked at gas stations.
Installation, commissioning, and maintenance of explosion-proof pan tilt cameras
With the continuous development of safety monitoring technology, explosion-proof pan tilt cameras are increasingly widely used in many fields, especially in high-risk industries such as petrochemicals and coal mines. Due to its high-definition image quality, flexible rotation, and strong explosion-proof performance, it has become an important equipment for modern security monitoring.1、 Installation and debugging1. Environmental assessment: Before installation, the installation environment should be evaluated first. Ensure that the installation site meets explosion-proof requirements, stays away from flammable and explosive materials, and considers the camera's field of view coverage and lighting conditions.2. Installation location selection: Choose a suitable installation location according to actual needs. Generally speaking, it should be installed at a height where the target area can be observed from all angles, such as wall corners, beams, or poles, to ensure that there are no blind spots in the monitoring.3. Installation and fixation: Use a dedicated installation bracket and screws to fix the camera in the selected position, ensuring a secure installation and not easy to shake. During installation, it is important to avoid damaging the explosion-proof casing and internal components of the camera.4. Power supply connection: According to the power requirements of the camera, connect a suitable power supply and ensure that the power supply voltage is stable. Meanwhile, explosion-proof power cords and junction boxes should be used to prevent electrical sparks from causing explosions.5. Network connection: Connect the camera's network cable to the switch or router in the monitoring center to ensure smooth network connectivity. During the connection process, attention should be paid to the protection and shielding of network cables to avoid electromagnetic interference.6. Software configuration: Configure the explosion-proof pan tilt camera through monitoring software, setting parameters such as image resolution, frame rate, and bitstream to meet practical needs. At the same time, adjust the angle and focus of the camera to ensure clear monitoring images.2、 Maintenance and upkeep1. Regular inspection: Regularly inspect the explosion-proof pan tilt camera, including the integrity of the casing, lens cleanliness, and the connection of power and network cables. Problems should be promptly addressed to avoid affecting monitoring effectiveness.2. Cleaning and maintenance: Regularly clean the lens and casing of the camera to maintain clarity and aesthetics. When cleaning, special cleaning cloths or cotton swabs should be used to avoid using chemical cleaners or water for direct cleaning.3. Dust and moisture prevention: In high humidity or dusty environments, dust and moisture prevention measures should be taken, such as installing protective covers or using desiccants, to prevent moisture or dust accumulation inside the camera.4. Lightning protection measures: In areas with frequent lightning strikes, corresponding lightning protection measures should be taken, such as installing lightning rods or surge protectors, to protect the camera from lightning damage.5. Software updates: Pay attention to the software updates of explosion-proof pan tilt cameras in a timely manner, and regularly upgrade the software to improve the stability and safety of the equipment.6. Backup storage: Regularly backup monitoring data to prevent data loss. At the same time, regularly check the integrity and availability of backup data to ensure timely recovery when needed.In short, the installation, debugging, and maintenance of explosion-proof pan tilt cameras are professional and meticulous tasks. Only correct installation and careful maintenance can ensure the normal operation and monitoring effect of the camera. I hope the introduction in this article can be helpful to users and provide strong support for security monitoring work.
