为了使制冷压缩机现代化,在德意志民主共和国广泛地使用了由2-3毫米的板状卡普隆制造的阀片。这些阀片在压缩氢气、氮氢混合气、甲醇、氨和各种牌号的氟氯烷的压缩机中很好地工作着。在最高压缩温度100℃和压力差25绝压下,这样的阀片工作11,000小时。[1] 压缩机中的卡普隆阀片破坏时,不会看到阀座的任何损伤以及气缸——活塞组件的擦伤。 有卡普隆嵌入件的活塞环同样很好地说明了这一点[2],[3]。嵌入物的高度根据结构条件选择,且不小于半个活塞环高度,而嵌入物的径向宽度——不小于环的2/3径向宽度。
In order to modernize the refrigeration compressor, a valve plate made of 2-3 mm plate-shaped capron is widely used in the German Democratic Republic. These valves work well in compressors for hydrogen, nitrogen and hydrogen, methanol, ammonia and various types of chlorofluorocarbons. Such valves operate for 11,000 hours at a maximum compression temperature of 100 ° C and a pressure differential of 25 absolute. [1] When the Kaplan valve in the compressor fails, no damage to the valve seat or bruising of the cylinder-piston assembly can be seen. Piston rings with Kapron inserts also illustrate this very well [2], [3]. The height of the insert is chosen according to the structural conditions and is not less than half the height of the piston ring, whereas the radial width of the insert - not less than 2/3 of the radial width of the ring.
