往复压缩机已有一百多年的历史,是很成熟的一种压缩机。但往复压缩机的突出矛盾是易损零件多,且寿命短,给现场维护带来极大的麻烦。我国对易损件的结构和材料的研究本来就很差,又在六十年代初批判“老大笨粗黑”的思想指导下,盲目赶超国外水平,一味追求体积小重量轻,不仅削弱了机械强度和刚度,增大设备振动,还使本来寿命就不高的易损件问题更为突出.因此,我国每年都要从国外引进一些工艺气体压缩机,其主要理由是国内没有合适的规格,新产品试制的可靠性差,价格还贵,特别是配套电机达不到防爆等级的要求,采用仪表质量较差,用户很不放心。在现有的规格中,
Reciprocating compressor has a hundred years of history, is a very mature compressor. However, the prominent contradiction of the reciprocating compressor is the fragile parts, and short life, bringing great trouble to the site maintenance. China’s research on the structure and materials of wearing parts has always been very poor. Under the guidance of the critique of “stupid, stupid blacks” in the early 1960s, blindly catching up and surpassing foreign standards and blindly pursuing small and light weight not only weakened Mechanical strength and stiffness, increase equipment vibration, but also make the original life is not high consumable parts of the problem is more prominent.So, our country every year from abroad to introduce some process gas compressor, the main reason is that there is no suitable domestic specifications , New product trial reliability is poor, the price is also expensive, especially supporting the motor does not meet the requirements of explosion-proof grade, poor quality of the instrument, the user is not assured. In the existing specifications,
