What are the key points for the maintenance and care of stainless steel refrigeration equipment?

Although stainless steel refrigeration equipment has the advantages of corrosion resistance and durability, maintenance and care are essential to ensure its long-term efficient and stable operation. Surface cleaning of the equipment is the key. Although stainless steel materials themselves have strong corrosion resistance, in actual use environments, dust, oil stains, salt and other impurities are easily accumulated on the surface. If not cleaned in time, these substances may form an adhesion layer on the surface of the equipment, affecting the appearance of the equipment and even causing local corrosion. It is recommended to use a mild neutral detergent with a soft cloth or sponge for regular wiping, and avoid using detergents containing strong acids, strong alkalis or chlorides to avoid damaging the protective layer of the stainless steel surface, causing corrosion and scratches. When cleaning, do not use hard brushes or steel balls to prevent scratching the surface.

In addition to external cleaning, the normal operation of the internal refrigeration system also requires continuous attention. The operating pressure, temperature and refrigerant charge of the refrigeration equipment must be kept within the design range, which is not only related to the refrigeration effect of the equipment, but also directly affects the safety and life of the equipment. Regular detection and adjustment of these parameters can prevent the system from losing efficiency due to abnormal pressure or refrigerant leakage, or even causing mechanical damage. At the same time, the refrigerant pipelines and related valves should also be checked regularly to ensure that there are no leaks, rust or mechanical damage. The tightness of the connection parts should be carefully confirmed, and any looseness may cause leakage problems. For aged or damaged valves and seals, they should be replaced in time to avoid the expansion of faults.

Fans and condensers are key components, and their cleanliness directly affects the heat dissipation efficiency of the equipment. Condenser fins and fan blades often accumulate dust due to dust and impurities in the air, causing air circulation to be blocked, which weakens the condensation effect and increases the burden on equipment operation. It is necessary to use appropriate tools (such as soft brushes and air guns) for cleaning regularly to ensure good ventilation and heat dissipation performance of fans and condensers. In addition, the electrical parts of the equipment, such as motors, wires and control panels, also need to be checked regularly. If the electrical components are aging, loose or short-circuited, it will bring safety hazards and equipment failures. Keeping the electrical system safe and stable not only prolongs the life of the equipment, but also ensures the safety of operators.

In order to avoid unnecessary consumption and mechanical wear of the equipment, try to avoid idling for a long time. Long-term no-load operation not only wastes electricity, but may also cause abnormal wear of mechanical parts, affecting equipment performance and life. It is recommended to shut down the equipment when it is not needed and arrange the equipment operation time reasonably.

Mechanical moving parts such as fan bearings and motor bearings need to be lubricated regularly. Lubricating oil can reduce friction and avoid premature wear or heating failure of bearings. Lubricating oil should be added to these parts regularly according to the recommendations of the equipment manufacturer to ensure their smooth operation.

It is very important to establish a complete maintenance plan and detailed records. By formulating scientific and reasonable inspection cycles and maintenance contents, and keeping detailed records of each maintenance, it can help to timely discover potential problems of equipment, track maintenance history, and thus carry out targeted preventive maintenance, avoid sudden equipment failures, and ensure long-term stable operation of equipment.
