L型往复式压缩机具有体积小、重量轻、结构紧凑等优点,故在我国中、小型化肥厂中运用较为广泛。但这种压缩机的滑道往往都和机身铸成一体,滑道磨损后,维修时不能根据实际磨损程度给予适当修复,这是设计上的先夭不足所造成。尽管机体采用了高强度铸铁HT21-40,但滑道的磨损仍很严重,这样影响了十字头与滑道的配合精度(原间隙为0.18～0.25mm),造成了压缩机运转时振动厉害、噪音大的弊病。这种弊病对于卧式滑道来说,较立式滑道更为突出。
L-type reciprocating compressor with small size, light weight, compact structure, etc., so in our country, small-scale fertilizer plant is widely used. However, this compressor slide and the fuselage are often cast into one, slide wear, maintenance can not be properly repaired according to the actual degree of wear and tear, which is caused by the lack of design first. Despite the use of high-strength cast iron body HT21-40, but the slide wear is still very serious, thus affecting the crosshead and the slide with the precision (the original gap of 0.18 ~ 0.25mm), resulting in vibration when the compressor operation, The big drawback of noise. This disadvantage for the horizontal slide, compared with vertical slide more prominent.
