Any kind of machinery needs daily maintenance, so as to reduce the cost and extend the service life of the machine. Below, the editor of Dejieli briefly introduces the work required for the daily maintenance of the quick-freezer-type quick-freezer:

1. The lubricating oil of the quick-freezer-type quick-freezer must be checked regularly. The main function of lubricating oil is to ensure the normal operation of the quick-freezing machine and the efficiency of the machine. To choose the lubricant of the quick-freezer-type quick-freezer on a regular basis, first use it within the specified range, and do not change the brand casually. Therefore, in the process of using the quick-freezer-type liquid nitrogen quick-freezer, it is necessary to check the quality and quantity of the lubricating oil of the machine regularly and replace it regularly.

2. Because the operating power of the quick-freezer-type quick-freezer is relatively large, a certain amount of heat will be generated during use. Therefore, during the use of the quick-freezing machine, the oil level and oil pressure of the quick-freezing machine should be checked regularly to ensure the working efficiency of the quick-freezing machine.

3. always pay attention to the daily cleaning of the quick-freezer-type quick-freezer. Cleaning work is very important for the quick-freezer-type liquid nitrogen quick-freezer. During the daily use of the quick-freeze Measures to ensure the cleanliness of the quick-freezer-type liquid nitrogen quick-freezer, so that not only the normal operation of the quick-freezer-type liquid hydrogen quick-freezer can be guaranteed, but also the service life of the quick-freezer-type liquid nitrogen quick-freezer can be extended in a fixed manner.

Operating procedures

1. Start-up inspection: Before turning on the quick-freezer-type quick-freezer, the workshop operator should check whether the various protective switches of the quick-freezer-type liquid hydrogen quick-freezer are useful and reliable. Whether there are sundries inside the quick-freezer, whether there is accumulated water, and whether the evaporator is clean and transparent. Turn on the quick-freezer-type quick-freezer mesh belt and the fan for a trial run for 1-2 minutes. Check whether the mesh belt is running smoothly and whether the fan is running without noise. If there is any problem, notify the maintenance worker in time. When the temperature drops to close to the temperature required by the process, the products can be placed. When placing them for the first time, pay attention to the products should be placed in a single row, and there should be a fixed spacing (between 5cm-10cm) between the products to prevent one side of the mesh belt Excessive force causes the belt to turn over. The mesh belt runs for a short time of 20 minutes, and a long time is generally 120-180 minutes. During the operation of the quick-freezer-type quick-freezer, if there is a failure, the personnel in the machine room should be notified in time, explain the reason, and facilitate the machine room personnel to adjust the equipment. Stop the mesh belt or fan running during normal operation of the machine, otherwise it will cause the refrigerating machine to be shut down due to flooding or overload. In the process of shifting, the quick-freezing machine-type quick-freezing machine is strictly forbidden to run without gears, or to keep the product in the quick-freezing machine-type liquid nitrogen quick-freezing machine, causing energy waste. When encountering sudden problems, such as ammonia leakage, the pilot should notify the personnel in the engine room as soon as possible. The squad leader should organize the evacuation of the on-site personnel in an orderly manner, and the pilot and squad leader must be able to use the canister correctly.

2. Shutdown operation: When the quick-freezer-type quick-freezer is shut down, the operator should notify the personnel in the machine room half an hour in advance and sign the shutdown. Evaporative recovery, causing the pressure to rise too fast after shutdown). Equipment cleaning and cleaning: When the quick-freezer type quick-freezer is flushed, the main power switch of the machine is turned off, and a useful warning sign is hung! The operator first checks whether the flushing valve is opened correctly, and then informs the personnel in the machine room and signs it. Before the flushing water pump can be turned on, the personnel in the engine room should go to the site to supervise the flushing situation. After the flushing is completed, notify the personnel in the engine room to stop the water pump. The flushing water pipeline is blocked by ice, which will affect the next flushing).

3. Maintenance: The quick-freezing machine type quick-freezing machine is a large-scale equipment, and the belt turning will cause serious damage to the equipment or even the scrapping of the equipment. It is strictly forbidden to place too many products, and maintenance workers should pay attention to the timely maintenance and replacement of reducers, bearings, and chains. Every week, the operator shall check whether the conveyor belt chain is unwelded, whether the mandrel is bent, whether the mesh is broken or warped, and if it is damaged, notify the maintenance worker to repair or replace it in time. Lubricate the drum bearings in time. It is recommended to replace the drum chain of the quick-freezer-type liquid nitrogen quick-freezer with a utilization rate of more than 80% every 12 months. Drum reducer and mesh belt tension reducer are inspected every 2 months, 6 months for maintenance, and 24 months for the reducer (including motor) to be replaced. The electrical part should be protected from moisture. The power distribution facilities should be cleaned every three months, and the lines should be checked for looseness, and the loose ones should be tightened; the maintenance of the frequency converter should be carried out in accordance with the requirements of the frequency converter manual.
