陽春陽東區(qū)北慣鎮(zhèn)殼牌468液壓油-潤滑脂經(jīng)銷
1、合適的粘度和良好的粘溫性能，以保證液壓元件在工作壓力和工作溫度發(fā)生變化的條件下得到良好潤滑、冷卻和密封。
2、良好的極壓抗磨性，以保證油泵、液壓馬達(dá)、控制閥和油缸中的摩擦副在高壓、高速苛刻條件下得到正常的潤滑，減少磨損。
3、優(yōu)良的抗氧化安定性、水解安定性和熱穩(wěn)定性，以抵抗空氣、水分和高溫、高壓等因素的影響或作用，使其不易老化變質(zhì)，延長使用壽命。
4、良好的抗泡性和空氣釋放值，以保證在運(yùn)轉(zhuǎn)中受到機(jī)械劇烈攪拌的條件下產(chǎn)生的泡沫能迅速消失；并能將混入油中的空氣在較短時(shí)間內(nèi)釋放出來，以實(shí)現(xiàn)準(zhǔn)確、靈敏、平穩(wěn)地傳遞靜壓。
5、材質(zhì)銹蝕和降低使用性能。
6、良好的防銹性，以防止金屬表面銹蝕。1. Proper viscosity and good viscosity-temperature performance to ensure that the hydraulic components in the working pressure and temperature changes under the conditions of good lubrication, cooling and sealing. 2. Good extreme pressure and anti-wear performance, to ensure that the oil pump, hydraulic motor, control valve and cylinder friction pair in high pressure, high-speed harsh conditions to get normal lubrication, reduce wear. 3. Excellent anti-oxidation stability, hydrolytic stability and thermal stability, to resist the influence of air, moisture, high temperature, high pressure and other factors, so that it is not easy to aging deterioration, extend service life. 4. Good foam resistance and air release value to ensure that the foam produced under the condition of severe mechanical agitation in operation can quickly disappear, and can be mixed with the air in the oil to release in a relatively short time, in order to achieve accurate, sensitive and smooth transmission of static pressure. 5, material corrosion and reduce the use of performance. 6, good rust resistance to prevent the metal surface rust.
