黃石西塞山下陸區(qū)美孚2號(hào)潤(rùn)滑脂-導(dǎo)軌油銷(xiāo)售潤(rùn)滑脂2號(hào)和3號(hào)有何區(qū)別? 1、就是軟硬的區(qū)別。2號(hào)和3號(hào)是只是它的NKGI號(hào)數(shù)，也就是針入度，2號(hào)在265-295，最常用，3號(hào)的在220-250，較硬，一般用于要求具有抗水或抗固體雜質(zhì)污染的應(yīng)用中，減少設(shè)備磨損。3#硬一點(diǎn)，多用手工涂抹，2#稍微軟硬點(diǎn)，多用機(jī)器加注、也可手工涂抹。使用性能無(wú)區(qū)別。 2、在比較鋰基潤(rùn)滑脂2號(hào)和3號(hào)的區(qū)別時(shí)，我們發(fā)現(xiàn)兩者在多個(gè)方面存在差異。首先，它們的錐入度有所不同。2號(hào)和3號(hào)代表了潤(rùn)滑脂的NLGI號(hào)數(shù)，也就是錐入度。根據(jù)NLGI的標(biāo)準(zhǔn)，潤(rùn)滑脂從000#到6#共有九種牌號(hào)，牌號(hào)數(shù)字越大，潤(rùn)滑脂的硬度也越大。 3、潤(rùn)滑脂1號(hào)、2號(hào)、3號(hào)的主要區(qū)別在于其粘度等級(jí)、使用溫度范圍以及應(yīng)用場(chǎng)合的不同。首先，從粘度等級(jí)上來(lái)看，1號(hào)、2號(hào)、3號(hào)潤(rùn)滑脂分別代表了不同的粘度級(jí)別。潤(rùn)滑脂的粘度是衡量其抵抗剪切力的能力，也就是它的流動(dòng)性如何。通常情況下，數(shù)字越大，粘度越高What is the difference between grease No.2 and No.3? 1. It's the difference in hardness. No.2 No.3 are just their NLGI numbers, which is the penetration, No.2 is between 265-295, the most commonly used, No. is between 220-250, harder, generally used in applications requiring resistance to water or solid impurities, to reduce equipment wear. No.3 is harder and often used for manual application, No.2 is slightly softer and harder and is often used for machine filling and can also be applied manually. There is no difference in performance. 2. When comparing lithium-based greases No.2 and No.3, we find that there are differences between the two in several aspects. First, their cone penetration is. No.2 and No.3 represent the NLGI number of the grease, which is the cone penetration. According to the NLGI standard, there are nine grades of grease 000# to 6#, the larger the grade number, the harder the grease
