巢湖市長豐縣美孚傳動油-導(dǎo)熱油銷售點美孚424液力傳動油是424號油。 美孚424液力傳動油（Mobilfluid 424）是超高性能的多用途拖拉機潤滑油，專門調(diào)制以符合或超越傳動裝置和液壓油的規(guī)格采用精密濾芯過濾液壓油，使油品的污染度長期保持在NAS<8級，設(shè)備自帶的濾芯一般精度太差，不能保證液壓油的潔凈度。因為液壓站的容臟極限只有5um，而自帶濾芯的精度往往要大于這個尺寸，科學(xué)規(guī)定一般液壓站的污染度要求控制在NAS小于8級;對于有伺服機構(gòu)的設(shè)備要求更高，要小于7級。若你拆過伺服閥，那你就什么都明白了，為什么液壓油的污染度要控制得這么高。買個精密濾油機進行在線過濾，有些濾芯精度已經(jīng)達到了0.1umMobilfluid 424 is a 424 oil. Mobilfluid 424 is an ultra-high- multipurpose tractor lubricating oil, specially formulated to meet or exceed the specifications of transmission and hydraulic oil. The hydraulic oil is filtered using a precision filter element, which ensures that the pollution level remains at NAS<8 for a long time. The filter element provided with the equipment is generally too coarse to guarantee the cleanliness of the hydraulic oil. Because tolerance of the hydraulic station is only 5um, and the accuracy of the built-in filter element is often greater than this size, it is scientifically stipulated that the pollution of the general hydraulic station should be controlled within NAS<8; for equipment with servo mechanisms, the requirements are higher, it should be less than 7. If have ever disassembled a servo valve, you will understand why the pollution level of the hydraulic oil needs to be controlled so high. It is best to buy a precision oil for online filtration, and some filter elements have reached an accuracy of 0.1um
