Points of attention for the use and maintenance of negative pressure weighing room
Points of attention for the use and maintenance of negative pressure weighing roomThe correct use and maintenance of the negative pressure weighing room is the key to ensuring its stable performance and extending its service life, just like taking good care of a right-hand man to keep it in the best condition at all times, providing a reliable guarantee for our work.Installation requirements When installing the negative pressure weighing room, it is necessary to choose a flat and stable working platform, which is like building a solid "stage" to avoid errors or even damage to the equipment due to vibration or tilt. At the same time, ensure that there is enough space around the equipment to facilitate the operator's access and daily maintenance of the equipment, it is generally recommended to reserve at least 50 centimeters of space around the equipment. Moreover, the installation location should be far away from heat sources, water sources, and strong electromagnetic interference sources, so as not to affect the normal operation of the equipment. For example, do not install the negative pressure weighing room near large motors, transformers, and other equipment to prevent electromagnetic interference from affecting the weighing accuracy. Pre-use inspection Every time before using the negative pressure weighing room, it is necessary to carry out a thorough and detailed inspection, just like a pilot checking the aircraft before taking off, to ensure that every link is safe. First of all, check whether the appearance of the equipment is damaged, whether the components are firmly connected, whether the seals are intact, and whether there is gas leakage. Then, check whether the power supply is normally connected and whether the fan, lighting, and other equipment can start normally. Pay special attention to the status of the high-efficiency filter to see if it is dry and complete, and if there are no signs of damage or blockage. If the high-efficiency filter is found to have a problem, it should be replaced in time, otherwise, it will affect the purification effect of the air, resulting in pollution of the weighing environment. Operating specification When using the negative pressure weighing room, the operator must strictly abide by the operating specifications, which is an important criterion to ensure the accuracy of weighing and the safety of the equipment. Before operation, wear protective equipment such as overalls, gloves, masks, etc., to avoid pollution of the work area caused by dust and microorganisms carried by oneself. When weighing, the material should be handled gently to avoid large movements in the working area and prevent large airflow disturbances that affect the accuracy of weighing. At the same time, be careful not to let the material fall on the weighing table or work area, once there is a spill, should immediately stop the operation, and clean up before continuing. For example, when weighing volatile chemicals, it is necessary to quickly put them into the weighing container, and close the container cover in time to reduce the pollution of volatile gases to the air. Routine maintenance Daily maintenance is the basic work to maintain the good operation of the negative pressure weighing room, just like regular maintenance of the car, which can find and solve small problems in time to avoid major failures. After each use, it is necessary to clean the dust and debris on the surface of the equipment in time, wipe the weighing table, outer box, and other parts with a clean wet cloth, but pay attention to avoid the use of corrosive detergent, so as not to damage the surface of the equipment. It is also necessary to check the status of the filter regularly, observe whether the primary and medium effect filters are dirty, and replace them in time if necessary. In general, the primary filter is replaced every 1-2 months, and the medium filter is replaced every 3-6 months. At the same time, it is necessary to check the operation of the fan and listen to whether there is abnormal sound, if there is abnormal, it should be stopped in time for inspection. Regular maintenance In addition to routine maintenance, regular maintenance is also essential. Regular comprehensive inspection and maintenance of the equipment can ensure that the performance indicators of the equipment are always in the best condition. It is generally recommended to carry out deep maintenance every six months or a year. During maintenance, it is necessary to overhaul and maintain important components such as the fan and the electric control box, check whether the fastening bolts of the fan are loose, whether the motor is running normally, and whether the wire joints are firm. The integrity of the high-efficiency filter should also be tested, and if the leak is found to exceed the specified range, it should be repaired or replaced in time. In addition, testing instruments such as differential pressure meters and anemometers should be calibrated every year to ensure the accuracy of their measurement data. |
