一、概述: 1.主要作用与性能: 阀片是压缩机吸排气阀中最重要的零件之一,在压缩机上处于极重要的地位。当压缩机运转时,阀片担负分配气体的工作。它在高至180℃的温度下受到每分钟350-1,500次循环频率的动力震动负荷。由于阀片在变动负荷的复杂条件下工作,因而促使它早期磨损。此外,当温度达到180℃时,气体介質也引起金属的腐蚀,对阀片产生有害的影响,而降低阀片的使用寿命,因此,对阀片的材料及制造技术要求都较高。其主要的工艺任务:是保证阀片具有较高的寿命、几何精度与表面光洁度。
First, an overview: 1. The main role and performance: Valve is the compressor suction valve in one of the most important parts in the compressor in a very important position. When the compressor is running, the valve is responsible for distributing the gas. It is subjected to a dynamic shock load of 350-1,500 cycles per minute at temperatures up to 180 ° C. Due to the variable load valve working in complex conditions, thus promoting its early wear and tear. In addition, when the temperature reached 180 ℃, the gas medium also causes metal corrosion, the valve has a detrimental impact, and reduce the life of the valve, therefore, the valve material and manufacturing technology are higher. Its main technical task: to ensure that the valve has a high life expectancy, geometric accuracy and surface finish.
