原来局限于小功率轻便装置的全无油压缩机,目前在尺寸,耐用性,以及效率方面可与同类型的有润滑压缩机相匹敌,因此,在需用全无油空气的场合,选择成本低的全无油压缩机是合适的。对于低于25马力的压缩空气系统来说,以往复活塞式压缩机作为压缩气源用得最为广泛。但这种压缩机通常必须加润滑剂才能保证运转寿命长和效率高。所以在运转时,一些润滑剂不可避免地随着排出气体进入系统里,导致阻塞一些精密零件或者污染最终产品。 The all-oil-free compressor, originally limited to low-power light fittings, is currently comparable in size, durability and efficiency to lubricated compressors of the same type, so choose the cost Low all oil-free compressor is suitable. For the compressed air system below 25 horsepower, the reciprocating piston compressor is the most widely used as a compressed air source. However, such compressors usually have to be lubricated to ensure long service life and high efficiency. So in operation, some lubricant inevitably comes into the system as the exhaust gasses, clogging some precision parts or contaminating the end product.
