loading pole中文什么意思

例句与用法

1. When the temperature to gas pipelines , temperature packets of material expansion , the pressure rise , inflation pressures are rising corrugated box , corrugated promote the expansion thrust to overcome the spring - loaded pole resistance , the ball - type valve opened for big change ; when the gas pipeline to reduce the temperature , temperature of the material swelling up , the pressure lowered inflation corrugated box pressure also reduced , spring - loaded pole compressed corrugated of resistance to thrust , spherical valves open for smaller ; this constant push and pull adjustment for the balance , as long as refrigeration cycle continue
   当回气管道温度升高，感温包内的物质膨胀，压力升高，膨胀波纹箱内压力也升高，波纹腔膨胀推动推力杆克服弹簧阻力，球型阀开度变大；当回气管道温度减低，感温包内的物质膨胀，压力降低，膨胀波纹箱内压力也降低，弹簧阻力推动推力杆压缩波纹腔，球型阀开度变小；如此不断的进行推拉调整平衡，只要制冷循环继续下去。
