explosion proof CCTV camera

With the progress of scientific and technological development, some special industries have special requirements for monitoring, chemical, petroleum, coal and other occupations in the operating environment of the risk of explosive gases and perhaps the presence of dust, and thus the device explosion-proof camera is very necessary. So what problems will be encountered in the use of explosion-proof camera, and how to deal with it? This article will give you the answer.

In the process of use, explosion-proof cameras may encounter several problems:

1. Explosion-proof monitoring can not see the picture

　　The first view of the camera instrument imaging there is no problem, if the imaging is not a problem, please check the camera instrument power supply; if the power is normal, and then check the camera instrument transmission equipment (such as fiber-optic terminals, etc.); if the transmission equipment is good, and then check the joints of the transmission line; if the joints of the transmission cable is good, and then check the transmission cable; if the transmission cable is fine, and then look at the signal access equipment; if the signal access equipment is good, and then check the signal access equipment is good If the signal access equipment is good, and then check the signal access equipment system settings are not right.

2. Explosion-proof camera blurred picture

　　It is possible that the lens focus is not adjusted;

　 Glass, lens or CCD above the oil or dust; if it is blurred at night, it may be some manufacturers in order to save money, planning shortcomings, infrared lamps from the lens is too close to the formation of reflections, infrared lamps and lenses are too close to the camera, these types of products at night infrared are not good. So the choice of explosion-proof camera must be selected with experience, good reputation of the manufacturer.

3. Explosion-proof camera installed at the scene why no picture

　　Check whether the explosion-proof camera power supply is connected, whether the power supply voltage is satisfactory; BNC head or video cable is touching the outstanding; if the use of manual aperture lens need to check whether the aperture is open, automatic aperture lens needs to be adjusted; section LEVEL potentiometer to make the aperture in the appropriate position.

　　According to the above situation explosion-proof camera installed and used in the process of what problems will be encountered, what kind of technical measures should be taken?

　　1、Where the overall explosion-proof temporary power, prohibited in Zone 0 and Zone 1. Due to the 2 zone in normal operation is not likely to appear explosive gas mixtures, even if there is only a short period of time the existence of explosive gas mixtures environment, so through the implementation of good organizational and technical measures can be carried out after the temporary use of electricity operations.

　　2、The use of portable combustible gas alarm for on-site detection, explosive gas concentration does not exceed 10% of the specified value can be regarded as non-explosion-proof area.

　　3、Use explosion-proof ventilator to set up temporary local strong ventilation, reduce the explosive gas concentration, maintain a relatively positive pressure.

4、The use of flame-retardant canvas and other obstacles to isolate, limit the diffusion of heavier-than-air explosive gas mixtures, reduce the scope of the explosion hazardous area.

5、The device area, tank area and other areas of the shaft, pit, cable trench and steam pipe ditches and other premises have deposited explosive gases, should be checked, tested to prevent the accumulation of explosive gases in the dead space.

　　6、When an accident occurs in the production unit, the production must be sampling, dehydration, discharge and other operations. Temporary use of electricity is likely to cause an explosion and fire accidents, the power user must absolutely obey the command of the production post personnel, immediately stop the power, in the non-explosion-proof area of the power outage operation.

7、With explosion-proof performance of electrical tools and communication equipment, before use must carefully check the nameplate on the explosion-proof category, level, temperature group, when the use of the environment may not reach the level of the release of substances, temperature group, or the category is not right, should be regarded as non-explosion-proof electrical equipment.

In summary, as a monitoring equipment designed for explosive gas environment, explosion-proof camera has the features of explosion-proof, dust-proof, water-proof, high resolution and long life. In the actual application, should follow the relevant safety standards and precautions for use, and according to the use of the environment and the need to choose the appropriate equipment models and configurations. At the same time, choose the brand and manufacturer with perfect after-sales service system, which can provide better technical support and guarantee for the use process.Our ZUOAN is your reliable choice! If you have purchasing needs please spare no effort to contact us, ZUOAN will provide you with high quality products and services!
