Any type of machinery requires daily maintenance in order to reduce costs and extend its service life. Below, the Dejie Li editor will briefly introduce the work required for daily maintenance of a quick freezing machine:

1、 Be sure to regularly check the lubricating oil of the quick freezing machine. The main function of lubricating oil is to ensure the normal operation and efficiency of the quick freezing machine. The selection of lubricating oil for the quick freezing machine should be carried out regularly within the prescribed range, and the brand should not be changed casually. Therefore, in the process of using a quick freezing liquid nitrogen quick freezing machine, it is necessary to regularly check the quality and quantity of the lubricating oil in the machine and replace it regularly.

2、 Because the operating power of a quick freezing machine is relatively high, it generates a certain amount of heat during use. Therefore, during the use of the quick freezing machine, it is necessary to regularly check the oil level, oil pressure, etc. of the quick freezing machine to ensure its working efficiency.

3、 Always pay attention to the daily cleaning of the quick freezing machine. Cleaning work is very important for the quick freezing machine type liquid nitrogen quick freezing machine. In the daily use of the quick freezing machine type liquid nitrogen quick freezing machine, it is necessary to pay attention to its hygiene management, especially to take necessary measures in some hygiene blind spots on the machine to ensure the cleanliness of the quick freezing machine type liquid nitrogen quick freezing machine. This not only ensures the normal operation of the quick freezing machine type liquid hydrogen quick freezing machine, but also extends the quick freezing machine type liquid nitrogen quick freezing in a certain form

The service life of the machine.

Operating procedures

1. Startup inspection: Before starting the quick freezing machine, the workshop operator should check whether the protective switches of the liquid hydrogen quick freezing machine are effective and reliable. Is there any debris stored inside the quick freezing machine, is there any accumulated water, and is the evaporator clean and transparent. Start the quick freezing machine's mesh belt and fan for 1-2 minutes to check if the mesh belt runs smoothly and if there is any noise during the fan operation. If there are any problems, notify the maintenance worker in a timely manner for handling. When the temperature drops to near the required process temperature, the products can be placed. When placing for the first time, attention should be paid to placing the products in a single row with a fixed spacing (between 5cm-10cm) between them to prevent one side of the mesh belt from being subjected to excessive force and causing the belt to flip. The short running time of the mesh belt is 20 minutes, and the long running time is generally 120-180 minutes. During the operation of the quick freezing machine, if there is a malfunction, the personnel in the machine room should be notified in a timely manner, explaining the reason, so that they can adjust the equipment. It is strictly prohibited for non operators to start or stop the quick freezing machine, and the conveyor belt or fan should not be stopped during the normal operation of the quick freezing machine liquid hydrogen quick freezing machine, otherwise it will cause the refrigeration machine to wet or overload and stop. During the exchange process, it is strictly prohibited for the quick freezing machine to idle or leave products stuck in the liquid nitrogen quick freezing machine, resulting in energy waste. In case of sudden problems such as ammonia leakage, the operator should promptly notify the personnel in the computer room for emergency repairs. The team leader should organize the orderly evacuation of on-site personnel, and both the operator and the team leader must be able to use the canister correctly.

2. Shutdown operation: When the quick freezing machine is shut down, the operator should notify the personnel in the machine room half an hour in advance and sign off on the shutdown. It is prohibited to stop supplying ammonia to the machine room only after the product has completely left the quick freezing machine (which is not conducive to ammonia evaporation and recovery, causing the pressure to rise too quickly after shutdown). Equipment cleaning and cleaning: When the quick freezing machine is defrosting, turn off the main power switch of the machine and hang a warning sign! The operator first checks whether the defrosting valve is opened correctly, then notifies the personnel in the computer room and signs it before starting the defrosting water pump. The personnel in the computer room should go to the site to supervise the defrosting situation. After the defrosting is completed, notify the personnel in the computer room to stop the water pump. The operator should drain the accumulated water in the pipeline, close the defrosting water valve, and open the pipeline vent valve at the same time (to prevent ice blockage in the defrosting water pipeline, which will affect the next defrosting).

3. Maintenance: The quick freezing machine is a large-scale equipment, and flipping the belt can cause serious damage or even scrap of the equipment, which cannot be repaired; The main reason for flipping the belt is to place too many products or the two drums have asynchronous speeds. Therefore, the workshop must strictly prohibit placing too many products, and maintenance workers should pay attention to timely maintenance and replacement of reducers, bearings, and chains. Every week, the operator checks whether the conveyor belt chain is welded off, whether the core shaft is bent, and whether the mesh is broken or raised. If it is damaged, the maintenance worker should be notified in a timely manner for welding repair or replacement. Timely lubricate the drum bearings, and it is recommended to replace the drum chain of the quick freezing liquid nitrogen quick freezing machine with a usage rate of over 80% every 12 months. The drum reducer and mesh belt tension reducer should be inspected every 2 months, repaired every 6 months, and replaced every 24 months (including the motor). The electrical part should be protected from moisture, and the distribution facilities should be cleaned every three months, and the lines should be checked for looseness, and any looseness should be tightened; The maintenance of the frequency converter should be carried out according to the requirements of the frequency converter manual.
