In many fields with strict environmental requirements, such as scientific research, medical treatment, and electronic manufacturing, purification construction projects are like precise "ecological guardians", safeguarding the purity and stability of microscopic worlds. As Guangzhou Kunling Purification Equipment Co., Ltd., which has been deeply involved in the purification field, today we will have an in-depth discussion with you on the crucial aspects of the subsequent operation and maintenance of purification construction projects.

The air filtration system at all levels is the core defense line of purification projects. From primary efficiency filters to high-efficiency ones, each plays its part in intercepting "uninvited guests" like dust and microorganisms. During daily inspections, pay attention to the dust accumulation on the primary efficiency filters. When the filter screen becomes darker in color and the air resistance increases significantly (which can be monitored by a differential pressure gauge, and when the pressure difference exceeds the set range), replace it in a timely manner to avoid excessive impurities from penetrating and affecting the subsequent high-efficiency filtering effect. For high-efficiency filters, regularly conduct random inspections on their integrity to check for any damage or cracks. Generally, they should be replaced every 1 to 2 years according to the usage environment and duration to ensure that the filtering accuracy always meets the standards. For example, in pharmaceutical workshops, as it is related to the quality and safety of drugs, there should be no slack in this regard at all.

The temperature, humidity, and air circulation in the purified space rely on air-conditioning and ventilation equipment. Record the temperature and humidity data daily, and make slight adjustments to the cooling, heating, humidifying, and dehumidifying modules according to the standards of different scenarios (for example, in an electronic chip clean room, the required temperature is 22 ± 2 °C, and the relative humidity is 45% - 55%). Regularly clean the air-conditioning fans and air ducts to remove dust and the breeding grounds for microorganisms, removing obstacles for the smooth flow of air. Also, add lubricating oil to the fan bearings on time to reduce wear, lower the operating noise, and extend the service life of the equipment, ensuring that the air flow in the purified space is continuous, stable, and "fresh".

The enclosure structures of purification projects, such as walls, ceilings, and floors, seem static but are prone to dirt accumulation. Regularly wipe and clean the walls and ceilings to remove dust and stains. Check whether there are cracks or glue peeling at the seamless joints of the ground and the sealing rubber strips in the corners. Once any gaps are found, repair and seal them in a timely manner to prevent the leakage of unpurified air from the outside and damage to the overall indoor cleanliness. In medical laboratories, this can effectively block the invasion of external germs and safeguard the safety of experimental samples and operators.

Purification equipment involves numerous electrical lines, control cabinets, and other components. Conduct a special monthly maintenance for the electrical system. Check whether there are any hidden dangers such as damage, aging, or short circuits in the lines, and tighten the terminal blocks. Conduct functional tests on switches, relays, etc. in the control cabinets, clean up dust and debris to ensure accurate signal transmission and orderly equipment start-up and shutdown. For example, in the purification system of an operating room, the stability of the electrical system is related to whether the operation can be carried out smoothly, and there is no room for any mistakes.

For key components such as the compressors, evaporators, and condensers of purification air conditioners, invite professional technicians to disassemble and maintain them quarterly. For compressors, check the amount and pressure of the refrigerant, and supplement or adjust the refrigerant to ensure the cooling and heating efficiency. Carefully clean the fins of the evaporators and condensers to remove oil stains and scale, strengthening the heat exchange efficiency and ensuring that the "heart" of the equipment beats healthily and continuously outputs a high-quality purified environment.

If the purification project includes water supply and drainage facilities, regularly clean the pipelines. Use professional dredging agents and flushing equipment to remove the accumulation of scale and debris in the pipelines every quarter to prevent blockages from affecting water supply and drainage. Check the seals at the pipeline connections and valves, and use pressure testing to find and repair tiny leakage points in a timely manner to avoid water accumulation that may breed bacteria and damage the foundation of indoor cleanliness. The normal operation and maintenance of the water supply and drainage in food processing purification workshops are of great significance for the hygienic quality of products.

When the air volume in the purified space suddenly decreases or the air pressure becomes unstable, first check the operating status of the fan. Check whether it has stopped due to power failure, overload tripping, or whether the fan belt has broken or there is a motor failure. Then check whether there is any blockage in the air duct. Investigate whether the filters are seriously dusty or whether there are foreign objects blocking the air duct. For example, if the particle counter shows a sharp increase in dust particles and the air volume is small, it is mostly a problem with the filters and air ducts. Timely dredging and replacement of components can restore normal ventilation and purification.

When the temperature and humidity deviate from the set values, first examine the working conditions of the cooling, heating, humidifying, and dehumidifying modules of the air conditioner. Check whether the sensors have malfunctioned and are transmitting incorrect data. Calibrate or replace the sensors. Check whether there is any leakage in the refrigerant pipeline and whether the humidifying water is supplied normally. Abnormal temperature and humidity in electronic clean factories will interfere with the production accuracy of products, so precise troubleshooting and repair are urgent.

When the levels of dust and microorganisms exceed the standards, start checking from the source filters. If there are tiny, invisible damages to the high-efficiency filters, they are often the "culprit". Then consider the sealing of the enclosure structure. Use a smoke generator to test for leakage through gaps. At the same time, check whether the start-up frequency and running time settings of the purification equipment are reasonable. In pharmaceutical and biological research purification rooms, production needs to be stopped for a thorough inspection and repair when encountering such situations to strictly adhere to the "red line" of cleanliness standards.

The maintenance and troubleshooting of purification construction projects is a long-term "battle" throughout their entire life cycle, which is related to the quality, safety, and innovation achievements in many industries. Guangzhou Kunling Purification Equipment Co., Ltd., relying on its professional team and rich experience, customizes operation and maintenance plans for each purification project, safeguarding the purified space with ingenuity and helping our clients' businesses thrive in a high-quality environment. In the future, we will continue to conduct in-depth research and improve our services to inject more reliable guarantee power into the purification field.
