The criteria for judging the quality of explosion-proof cameras

The detailed parameters of explosion-proof cameras reveal their quality. If we only rely on the parameters provided by the manufacturer as a basis for judgment, it may be a bit lacking in basis, because some manufacturers provide parameters with moisture. Regarding this issue, explosion-proof cameras provide some suggestions for everyone to refer to.The first thing that can be determined is the shell of the explosion-proof camera. The high-quality shell is made of 304 stainless steel material or high hardness special carbon steel, which is not easy to burst, corrode, or deform, and its sealing performance should preferably reach IP68. To achieve explosion-proof, anti-corrosion, waterproof, and dust-proof capabilities.Secondly, the selection of monitoring lenses is crucial. A good IR night vision lens has precise focusing adjustment, fine coating on the surface of the lens, and excellent transparency; Many lenses even reach millions of pixels and can be matched with high line cameras, fully leveraging the advantages of high line cameras.For explosion-proof infrared cameras, infrared lights can also serve as a reference. For explosion-proof cameras, it is not only necessary to meet people's needs for daytime monitoring, but also to fulfill the mission of nighttime monitoring. Monitoring infrared lights is essential in night vision environments. From the first generation of infrared lamps to the current third generation, the arrangement of infrared lamps also determines the service life of the product. From this perspective, infrared lamps play an important and fragile role in explosion-proof cameras. A good infrared light board that emits light evenly and has a longer lifespan; The lamp board will be developed with a control board to regulate the voltage and current of the transformer in case of unstable voltage and current; Poor light boards not only use cheap wick, but also lack the most basic control board.So, choosing a high-quality explosion-proof camera solely based on the manufacturer's parameters is one-sided. The quality judgment criteria for explosion-proof cameras provided by Changzhou Delco can help people avoid some detours in their selection.

How to easily select explosion-proof camera manufacturers for procurement?

For customers who are new to the explosion-proof monitoring industry, they may feel overwhelmed and unsure when it comes to procurement. In fact, as long as they grasp the following aspects listed by the explosion-proof camera manufacturer, they can easily choose a suitable explosion-proof camera.　　1. Do you need anti-corrosion? If there is corrosive gas in the installation environment, it is necessary to choose products with explosion-proof and anti-corrosion functions, which mainly depends on the material of the product. For mild corrosion, high-quality 304 stainless steel material can be selected. If the corrosion is severe, 316 stainless steel material or 316L material can be selected; Of course, explosion-proof camera manufacturers can also choose other materials and apply corresponding anti-corrosion treatment to the product surface.2. What are the requirements for clarity? If it is an analog signal, how much TVL is required; If it is a network signal, how many tens of thousands of pixels are needed? Commonly used ones include 2 million pixels, 3 million pixels, or even higher.3. Is the lens fixed focus or zoom? If the subject monitored by the explosion-proof camera remains unchanged, a fixed focus lens can be selected; If you need to look both up and far, you usually choose a zoom lens.4. Do you need night vision function? It usually depends on whether the explosion-proof camera is installed indoors or outdoors; In general, indoor lighting is available and night vision function is not required; If installed outdoors, night vision function is generally required. In case of insufficient lighting, the infrared light will automatically turn on to meet the good monitoring effect.5. Do we need 3D surveillance? Stereoscopic monitoring refers to the ability to both look up and down, achieving comprehensive and three-dimensional control. If the project has such requirements, products with pan tilt function (which can rotate up, down, left, and right) can be selected.6. Do you have any requirements for the appearance of the product? Commonly used explosion-proof monitoring products have gun shaped, hemispherical, and spherical shapes; Double hanging, single hanging, or other complex shapes need to be selected based on the installation location and environment.7. Are there any requirements for price, warranty, and other aspects? If there are clear requirements for the above six aspects, then we can easily choose products. Of course, we cannot escape the mutual communication and negotiation in terms of price, delivery time, warranty time, and shipping cost, so as to choose products that are suitable for project needs.With the above precautions for selecting explosion-proof cameras, you can have a targeted selection when purchasing. Changzhou Delco explosion-proof camera manufacturers welcome everyone to follow.

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.
