As is well known, cold storage is composed of complex equipment and storage panels that make up the storage body. In winter, cold storage is like our skin. If we do not pay attention to maintenance, the losses caused will be incalculable and may even be damaged, affecting the production of the following year. Here are some winter maintenance methods and experiences for cold storage, for your reference only:
Why is that? Does it mean that cold storage equipment is easily damaged? Actually, it's not.
On a large scale, regularly maintaining and upkeep our cold storage equipment can effectively extend its service life, maintain the normal operation of the cold storage, and ensure its good performance. Especially for large cold storage equipment, as the investment in large cold storage is often significant and generally affects the normal operation of the entire enterprise, if related failures occur due to long-term neglect of equipment maintenance, the losses caused cannot be ignored. Therefore, we need to do a good job in maintenance during daily use.
So what should we do exactly:
1. If the cold storage equipment is restarted after a long period of suspension, the cooling rate should be controlled at the beginning of the equipment start-up. It is better to control the cooling rate at around 8-10 degrees per day, and maintain it for a period of time when the temperature drops to 0 degrees. Do not adjust it arbitrarily.
2. We also need to regularly maintain the storage boards of the cold storage equipment. For example, in daily use, we should avoid situations where hard objects scratch or collide with the storage board. The purpose of doing so is to prevent accidents such as dents and scratches caused by the impact of the storage board. In severe cases, it may also affect the cooling effect of the cold storage, leading to a decrease in the local temperature control effect of the cold storage.
3. Because our large cold storage is usually made up of many insulation boards, and the gaps between each board are where we need to maintain them. During construction, we usually seal these gaps with sealant, but if any sealing failure is found during use, it needs to be repaired in a timely manner.
4. Another point is the maintenance measures for the ground in large cold storage facilities. Some friends may ask why the floor of cold storage equipment still needs maintenance? It's not difficult to understand, because large prefabricated cold storage floors also use insulation boards, and in the later use process, there is usually a large amount of ice on our floors. Therefore, when cleaning these ice layers, we need to be careful not to use hard objects such as hammers or shovels to strike, as it will damage our floor insulation boards. If the insulation boards are damaged, it will also affect the insulation performance of the equipment.
