Bu turli omillarga bog'liq, masalan, kompressor turi, ishlash sharoitlari va moy sifati. Biroq, moyning umr ko'rish muddati asosan kompressorning ishlash muhitiga bog'liq. Oddiy sharoitlarda, kompressor moyini har 500 soatda yoki yilda bir marta o'zgartirish tavsiya etiladi. Ammo bu faqat tavsiya etilgan almashtirish vaqti bo'lib, haqiqiy vaziyatlar farq qilishi mumkin.
It is particularly important to emphasize that the factors accelerating the aging of compressor oil are moisture and dust in the air. Dust particles smaller than 15 microns circulate with the lubricating oil. When the concentration of dust particles smaller than 15 microns is too high, an oil change is necessary. Moisture in compressed air causes the lubricating oil to emulsify, losing its lubricating effect. Additionally, moisture leads to metal corrosion, and a large amount of corrosion products smaller than 15 microns also circulate with the lubricating oil, accelerating the aging of the compressor oil. So, changing the oil is like dialysis for patients with kidney disease; regularly replacing the lubricating oil is more beneficial for the operation of the compressor and is an important means to maintain the mechanical lifespan.
