How to maintain these refrigerator cars? You should know

The main purpose of refrigerated trucks is to ensure the quality of the products, especially during the holidays, the role of refrigerated trucks is even more important. However, it can also be found that many foods have begun to deteriorate in the transportation process. The reason is mainly due to improper use of refrigerated trucks. So, how to use refrigerator cars correctly?

The main purpose of refrigerated trucks is to ensure the quality of the products, especially during the holidays, the role of refrigerated trucks is even more important. However, it can also be found that many foods have begun to deteriorate in the transportation process. The reason is mainly due to improper use of refrigerated trucks due to improper use of refrigerated trucks.

Refrigeration unit maintenance:


Usually, the chassis engine is maintained and maintained according to mileage, while the refrigeration unit is designed to maintain and maintain according to the hours of engine operation. The usual refrigeration unit is 500-700 hours for maintenance and maintenance. It needs to replace the oil filter, fuel filter, and air filter; and pay attention to check the tightness of the belt and the leakage of the cooling system.


Individual brands of refrigeration units (such as the American Cool King) use synthetic or semi-synthetic motor oils instead of ordinary oils to meet the needs of environmental protection, thereby prolonging the maintenance time of the engine. Maintenance is usually done in 2000 hours. As a result, the waste of used motor oil is reduced. Therefore, scientific maintenance and maintenance can not only ensure the integrity of equipment, but also reduce operating costs.


Packing of goods:


In general, the goods used for refrigerated trucks are packaged. For non-ventilated containers for refrigerated goods, side-ventilated containers for fresh produce. The box must be compressive. The reason why refrigerated goods use non-ventilated boxes is because they contain moisture. Once there is wind blowing from the surface, the moisture of the goods will be lost, which will lead to a decline in the quality of the goods. In contrast, raw fresh goods are still in a state of breathing during storage and transportation, so they must maintain good ventilation.


Cargo handling:


Prior to loading, it is necessary to pre-cool or warm up the compartments prior to pre-cooling or preheating.


Prior to loading, the cabin needs to be pre-cooled or preheated so that the temperature inside the cabin can be kept the same as the temperature of the cargo, so as to guarantee the quality of the cargo. When loading, you must first measure the temperature of the loaded goods. The purpose of doing so is to keep the storage temperature of the goods in line with the transport temperature, prevent the loss of water due to large temperature changes of the goods, and cause quality changes of the goods. It is worth noting that, during loading (discharging), the refrigeration unit should be shut down to slow the rate of outside air entering the cabin.


With better quality refrigerated trucks, the ventilation effect on the six sides of the carriages is good, and there are no obstructions on the six sides of the cargo; good air circulation ensures that the goods can be transported under the proper temperature requirements. In order to ensure the ventilation effect, the general refrigerated truck floor is a ventilated aluminum rail floor, but there are also anti-skid floors. If it is a non-slip floor, it must be loaded with double-sided pallets to ensure the circulation of cold air on the floor.


In addition, during loading, it is necessary to ensure that the height of the goods is lower than the plane height of the air outlet, otherwise it will hinder the cold air flow. Keep a minimum distance of 225 mm between the top of the cargo and the roof.


In order to ensure the temperature of goods in the carriage, it is recommended to install bar-shaped curtains for refrigerated trucks for short-distance transport to prevent the cold air inside the carriage from quickly dissipating when unloading. Because different goods have different refrigerating temperature requirements, goods at different temperatures should not be placed in the same compartment. They can be separated by partitions or transported using multi-temperature refrigerated trucks.

The hydraulic support system used in mines is used to support equipment during the mining process of coal mines or other underground mines.
It mainly consists of hydraulic supports, hydraulic stations, control systems, and sensors.
Hydraulic support is the core component of the hydraulic support system used in mines, which uses hydraulic cylinders as the support force source,
Capable of supporting huge rock weights in underground mines. The hydraulic station provides a hydraulic oil source,
Hydraulic oil is transported to the hydraulic support through pipelines to achieve support function.
The control system is an important component of the hydraulic support system used in mines, which controls and monitors the hydraulic support through sensors and controllers. Sensors can monitor the status of the bracket in real-time, including support force
The controller controls the hydraulic support based on the feedback data from sensors, such as inclination and displacement, to ensure its stability and safety in the mine.
The hydraulic support system used in mines has advantages such as high support force, good stability, and safety and reliability,
Widely used in underground mining industries such as coal mines, metal mines, and non-metallic mines. With the continuous progress of technology and the continuous expansion of applications, hydraulic support systems for mines will continue to play an important role,
Provide strong support for the safe and efficient development of the underground mining industry.
