After many drivers have purchased refrigerated trucks, they will encounter many small problems of all sorts. I am troubled by these small problems every day. Therefore, the following Xiao Bian summed up some basic knowledge about refrigerated trucks and hoped to give some help to the refrigerated truck drivers.

What kind of temperature of the goods is easy to cool? When the ice cream is released, the temperature is about minus eighteen degrees, and this temperature is easier to lower. However, it is difficult for the temperature of the self-heating articles, such as the probiotic milk of Mengniu, fruits, vegetables and yeasts. The temperature of the box is knocked down, and the temperature of the goods does not necessarily fall. When the temperature of the cabinet dropped to minus 4 degrees Celsius, the temperature inside the probiotic cup was only 4 degrees Celsius. So whether the temperature can be lowered depends on the goods themselves.

Good quality chiller can spray fog in the box? This statement is definitely wrong. The main reason for the fog produced by the chiller is excessive moisture in the box, and it may be that the chiller's drainage is not smooth, usually we can from the temperature The table is judged. Of course, it can also be judged by the cooling water outlet outside the cooling chassis. If there is a continuous flow of water out of the box during the cooling process, this is a normal situation. If it is not, the artesian water outlet is blocked.

Does the exposure of the refrigerator to sunlight in the sun do not affect the cooling? The higher the ambient temperature outside the refrigerated vehicle , the worse the corresponding cooling effect. For example, the prolonged exposure of refrigerants under the sun and the high temperatures in summer are very severe tests for refrigerators. If the temperature on the chiller display does not reach the desired temperature of the goods, the chiller is negatively acting.

Ice cream delivery temperature is minus eighteen degrees, packing, opening the refrigerator cold box, the temperature indicator shows up to three or four degrees, or even seventy-eight degrees, do not be nervous This is just the temperature of the air inside the container. As the effect of the chiller continues, the temperature of the display will drop, and the temperature will drop in a short time, and the quality of the goods will not have any problems. The temperature of the display only shows the temperature of the air in the refrigerated compartment. It does not represent the temperature of the air inside the compartment. The specific heat of the air is relatively low and it is very easy to cause the temperature to rise. However, it does not mean that the temperature of the cargo has risen.

The advantage of large refrigeration capacity is that the cooling rate of the box is fast, the pressure in the compressor system drops quickly, and the horsepower consumption of the engine is less. However, the disadvantage is that the amount of electricity consumed by the battery is relatively large, and the battery is often depleted, and the phenomenon of fire cannot be sustained. This is particularly the case with diesel vehicles. The best principle for refrigerating trucks to install refrigerators is to match them. It's not good if they are big and small.

A Check Valve is also called Non-return Valve, that allows fluid to flow through it in only one direction. Check valves work automatically and most are not controlled by a person or any external control; accordingly, most do not have any valve handle or stem.

There are various types of check valves used in a wide variety of applications, e.g. swing check valves, piston check valves(lift check valves), wafer check valves(dual-plate and single-plate), tilting disc check valves. They provide various flow rates, closure times and mounting positions for different pipelines.

Check valves are used in many fluid systems such as those in chemical, and power plants, and in many other industrial processes. Kolink check valves can be with flanged ends, butt weld ends, socket weld ends and screwed ends, and are constructed with various materials of cast carbon steel, stainless steel, alloy steels, and forged steels.

The Cross-section of a Typical Cast Steel Swing Check Valve:

1) A hinge and hinge pin mounted to permit free movement of the disc.

2) Renewable welded-in or screwed-in seats provide a bubble tight joint.

3) Standard swing disc type, used in horizontal position for liquid application.

4) Internal hinge design eliminates body penetration and eases maintenance since all parts are accessible from the top. Through-body hinge Pin design also available for extra lever, counter weighter and damper.
