Explosion-proof cargo shower room routine maintenance points
Explosion-proof cargo shower room routine maintenance points(1) Cleaning and hygiene maintenanceKeeping the explosion-proof cargo shower clean and hygienic is the basis of maintenance. Regular cleaning of the interior and external surface of the shower can effectively prevent the accumulation of dust, dirt, etc., affecting the normal operation of the equipment and the purification effect. A thorough cleaning is recommended at least once a week. When cleaning, use mild cleaning agents and a soft cloth or sponge to wipe gently. Avoid using abrasive or corrosive cleaning agents to avoid scratching the protective coating on the surface of the device, reducing the explosion-proof performance and aesthetic appearance of the device. You can use a soft brush to clean some nooks and crannies that are difficult to clean. For example, in electronics manufacturing enterprises, due to the high cleanliness requirements of the production environment, the cargo shower room is simply cleaned every day, and deep cleaning is carried out once a week to ensure that the equipment is always in the best condition. (2) Maintenance and replacement of filters Filter is one of the core components of an explosion-proof cargo shower, and its performance directly affects the purification effect. The primary effect filter mainly filters large particles of dust, the medium effect filter further filters smaller particles, and the high-efficiency filter carries out fine filtration of small dust particles. Check the status of the filter regularly according to the time of use and the environment. In general, the primary filter is cleaned every 1-3 months, and when it is found that the filter surface is black and contains more dust, it should be cleaned or replaced in time. The filter should be checked every 3-6 months. If the resistance increases and the filtration efficiency decreases, cleaning or replacement should be considered. The replacement cycle of the high-efficiency filter is relatively long, generally 1-2 years, but if the wind speed is found to be significantly smaller, even if the replacement cycle is not reached, you should check whether the filter needs to be replaced. When replacing the filter, choose the same product as the original filter, and install it in strict accordance with the operation process. When installing, ensure that the arrow mark on the filter points in the direction of the airflow to ensure a good seal and prevent leakage. For example, in pharmaceutical companies, the filtration efficiency of the filter is regularly tested by professional testing instruments, and once the efficiency is found to be reduced, it is immediately replaced to ensure the cleanliness of the drug production environment. (3) Electrical system inspection The electrical system is a key part of an explosion-proof cargo shower, regular inspection of electrical lines, switches, sockets, and other components of the safety is very important, and can effectively prevent electrical failure caused by fire or explosion risk. Check the electrical system at least once a month, focusing on whether the line is aging, whether there is a short circuit, and whether the grounding is good. Check whether the insulation layer of the electrical line is damaged or cracked. If any problem is found, replace the damaged line in time. Check whether the contact between the switch and the socket is good and whether there is any abnormal situation such as loosening and igniting. For the grounding situation, use a professional grounding resistance tester to test to ensure that the grounding resistance meets the safety standard. In chemical enterprises, due to the more flammable and explosive substances in the environment, the inspection of the electrical system is more strict, in addition to regular inspection, a simple electrical safety inspection will be carried out before each use to ensure the safe operation of the equipment. (4) Fan and air duct maintenance The fan is the key equipment to provide the drizzle power, and the air duct is responsible for guiding the airflow. Check the operating status of the fan regularly, including noise, vibration, air volume, etc. If it is found that the fan noise is too large or the vibration is abnormal, it may be caused by the fan bearing wear, impeller imbalance, and other reasons, and should be stopped in time for inspection and maintenance. For example, by listening to the sound of the fan operation, if you hear abnormal friction or banging, you need to further check the internal components of the fan. Regular cleaning of dust in the air duct can ensure that the air path is smooth and maintains a good blowing effect. It is recommended to thoroughly clean the air duct every quarter, and use professional air duct cleaning tools, such as air duct cleaning robots, soft brush, etc., to thoroughly remove the dust in the air duct. In some large electronic manufacturing plants, automated air duct cleaning equipment will be used to clean the air duct regularly to improve maintenance efficiency. (5) Door body and seal maintenance The normal opening and closing of the door body and good sealing performance are important factors to ensure the function of an explosion-proof cargo shower room. Before use, every day, check whether the automatic closing and self-locking function of the door is normal. Gently push the door, and observe whether the door can be smoothly closed and whether it can be automatically locked after closing. If the door is not smoothly closed or can not be automatically locked, it may be that the door track has debris, the door hinge is loose or the door lock is faulty, and it is necessary to clean the track in time, tighten the hinge or repair the door lock. Periodically check the status of the sealing rubber strip. If the sealing rubber strip is aging, deformed, or damaged, resulting in a loose seal, replace it in time. When replacing the sealing rubber strip, choose the product with the same material and specifications as the original rubber strip to ensure that the installation is firm and the sealing is good. In food processing enterprises, due to the high hygiene requirements for the production environment, special attention will be paid to the maintenance of the door body and seal to ensure the tightness of the cargo shower and prevent external pollutants from entering the production area. (6) Operation record and troubleshooting Every time the explosion-proof cargo shower room is maintained, it is necessary to carefully record the maintenance time, maintenance content, replacement parts, and other information. These records not only help to track the operating status of the equipment but also provide an important basis for troubleshooting. When the equipment fails, such as the fan does not rotate, the air shower time is abnormal, etc., you can quickly determine the possible fault causes according to the operation records. For example, if the fan does not rotate after the filter is replaced during the latest maintenance, it is necessary to check whether the filter is installed correctly and whether it affects the normal operation of the fan. For common faults, we must master the basic troubleshooting ideas and solutions. When the fan does not rotate, first check whether the power supply is normal, and then check whether the motor of the fan is damaged and whether the control switch of the fan is faulty. When the air shower time is abnormal, check whether the setting of the electrical control system is correct and whether the time relay is damaged. Through the continuous accumulation of troubleshooting and troubleshooting experience, we can quickly and effectively deal with equipment failures and ensure the normal operation of an explosion-proof cargo shower room. |
