Refrigerated trucks are vehicles that are used to transport some fresh foods. What are their production principles as important transportation vehicles? What makes them have such different designs? Let's look at them together today. Studies of people know refrigerated trucks, refrigerated trucks compression refrigeration unit mainly composed of a refrigerant compressor, a condenser, a throttle valve and an evaporator, etc., although these different sets of devices mounted together in a fast, but they The volume is small. Here, the compressor is the host of the refrigerator. He can compress the low-pressure refrigerant gas from the evaporator through the piston, make it a high-temperature high-pressure gas, and discharge it to the condenser. Then the gas is obtained in the condensation gas. liquefaction. It can be learned that the refrigerant gas can be continuously sucked from the evaporator, and then the refrigerant is evaporatively compressed and sent to the condenser, and at the same time maintaining the difference between the pressure at the suction end and the discharge end, driving the cooling The agent circulates in one direction in a closed system, and cooperates with its main components to complete its phase change. This is the role of the compressor. The condenser of a refrigerated truck is one of the heat exchangers, and water or air is often used as its cooling medium, so that the heat evaporating the refrigerant can be transferred to the cooling water or the air, so that the high temperature and high pressure Refrigerant vapor condenses into a liquid under pressure. Therefore, it can be said that the condenser is the key component that makes the refrigerant from the gaseous state to the liquid state. The throttle valve is also called the expansion valve. When the refrigerant liquid flows out of the condenser and passes through the throttle valve, both the pressure and the temperature will decrease due to throttling. From the condensation pressure to the evaporation pressure, the condensation temperature To the evaporation temperature. In these processes, the important role of the throttle valve in the refrigeration system of a refrigerated truck is to throttle down the pressure, which is also a critical step. Here we see that there have some understanding of the principle of making it inside refrigerated trucks, refrigerated trucks refrigeration is the use of technology to produce an insurance environment, and then use this environment for some fresh were transported. The main feature of milling is intermittent cutting. The impact and vibration are more severe during the cutting process, which is not as stable as turning. Due to the high toughness of stainless steel materials, the chips are not easy to cut off, and the work hardening tendency is strong, which increases the unfavorable factors in the milling process. In summary, the characteristics of stainless steel milling are mainly manifested in the following aspects: Milling Service,Stainless Steel Milling Parts,Stainless Steel Milling,Stainless Steel CNC Milling,Axis Milling Pro Success Development Limited , https://www.prosuccess-metal.com
Â
1. The material has high toughness, high temperature strength, high hardness, difficult cutting deformation, and large cutting force in the chipping process.
2. The adhesion and fusion of stainless steel are strong, and the chips are easy to adhere to the edge of the milling cutter, which deteriorates the cutting conditions.
3. Due to intermittent cutting, large impact and vibration, coupled with the characteristics of stainless steel materials, the teeth of milling cutters are easy to chip
and wear,
4. Stainless steel has a strong work hardening tendency, and interrupted cutting will increase the tendency of hardening, making the cutting conditions worse,
5. Due to the comprehensive influence of the above factors, stainless steel is not easy to cut at high speed.
Therefore, the milling of stainless steel milling should take measures from the following aspects:
â‘ Choose a milling machine with higher power and less vibration.
â‘¡ Use tool materials with good impact toughness and wear resistance.
â‘¢Adopt appropriate tool structure and geometry.
â‘£ Select the appropriate cutting amount.
⑤ Select the appropriate cooling lubricant.
â‘¥ Operate correctly.
