大巴空調(diào)系統(tǒng)為大巴艙內(nèi)提供冷/暖氣。管路不僅粗大,而且長度較長。多數(shù)采用銅管材料或鋁管材料。
大巴用發(fā)動(dòng)機(jī)多為柴油機(jī),管路承載壓力較高并承受振動(dòng)較大,適配的管不僅材料較厚,并對(duì)焊接提出較高要求。
Bus air-condition system provides cool / warm air for bus compartment. This kind of pipe is thick and long that mostly made of copper pipe or aluminium pipe.
Most bus engine is diesel engine. This kind of pipe is exposed to higher pressure and greater vibration, so it requires thicker material and higher quality for welding.
