超高压压缩机在高压聚乙烯装置中的发展前景

The Prospect of Extra High Pressure Compressor in LDPE Plant

高压聚乙烯装置超高压压缩机出口压力可达 30 0MPa ,在世界范围内此种超高压压缩机供货商只有瑞士的苏尔寿和意大利的新比隆 ;其产品各有特点。随着高压聚乙烯的技术不断向前发展 ,作为高压聚乙烯心脏设备之一的超高压压缩机也需不断发展 。

The extra high pressure compressor's discharge pressure is about 300 MPa in LDPE plant, which is one of the critical equipments in LDPE plant. It was SULZER in Switzerland and NUOVO PIGNONE in Italy that can only manufacture the extra high pressure compressor, and their products have their own characters respectively. Today the extra high pressure compressor must meet the needs of LDPE technology development along with the development of LDPE technology.
