1.英国HAMWORTHY ENGINEERING生产一种高压压缩机组——双曲拐对置式水冷机组,其进口压力为2bar,排出压力为450bar,容量为250～270m~3/h。该机组的最大特点是全部采用组合阀。在较大直径的情况下,采用组合阀过去还不多见。组合阀对扩大气阀通道面积,降低气阀阻力,减小功率消耗,改善运行情况,提高使用寿命都是有利的。 2.澳地利L.M.F公司开发了一种螺杆——活塞串联机组。该机组低压部分由螺杆压
1. HAMWORTHY ENGINEERING produces a high-pressure compressor unit - hyperboloid opposite water-cooled units, the inlet pressure of 2bar, discharge pressure of 450bar, capacity of 250 ~ 270m ~ 3 / h. The most prominent feature of this unit is the use of a combination valve. In the case of larger diameters, the combination valve used to be rare. Combined valve to expand the valve area of the valve, reducing valve resistance, reduce power consumption, improve operating conditions, improve service life are beneficial. 2. Australia L.M.F company developed a screw - piston series unit. The low-pressure part of the unit by the screw pressure
