液压油
产品描述
威协油是优质的合成，低污染，低胶成型，抗磨液压油，是专门设计用于现代铝轧制米尔斯。他们的设计，以满足最先进的生产力的铝冷轧米尔斯的最新要求。常规液压油的泄漏导致的铝轧制油系统的污染，这可能会导致在成品金属表面上的染色和胶形成。然而，卷的油污染显著降低这种效应威协。威协具有良好的抗磨性能，优异的氧化稳定性和良好的防锈和防腐蚀保护。尽管威协是一个综合的产物，它与矿物油混溶，因此改变传统的液压油威协可以相对容易地实现。由于基础油的性质、威协不符合美国FDA规定21 CFR 178.3910（一）。如果这是必需的，应该用威h。
Wyrol HS
Hydraulic Oil
Product Description
Wyrol HS oils are premium synthetic, low staining, low gum-forming, anti-wear hydraulic fluids that are specifically designed for use in modern aluminium rolling mills. They are designed to meet the most up-to-date requirements of high productivity aluminium cold rolling mills. Leakage of conventional hydraulic fluids leads to contamination of the aluminium rolling oil system; this may cause staining and gum formation on finished metal surfaces. However, contamination of the roll oil with Wyrol HS significantly reduces this effect. Wyrol HS has good anti-wear properties, excellent oxidation stability and good protection against rust and corrosion. Although Wyrol HS is a synthetic product, it is miscible with mineral oil, so change over from conventional hydraulic oil to Wyrol HS can be achieved with relative ease. Due to the nature of the base oil, Wyrol HS does not meet U.S. FDA Regulation 21 CFR 178.3910(a). If this is required, Wyrol H should be used.
Features and Benefits
Wyrol HS are high performance synthetic hydraulic fluids, which exhibit very low staining characteristics reducing the potential of production material rejects. Their excellent oxidation stability and good anti-wear protection properties result in longer oil life and improved hydraulic component performance.
Wyrol HS oils offer the following benefits:
-
Low staining characteristics reduce the potential of production rejects
-
Good anti-wear properties reduce hydraulic system component wear and extend service life
-
Excellent oxidation stability minimises system deposits and improves oil life, reducing maintenance costs
Applications
-
Hydraulic systems in aluminium cold rolling mills
-
Suitable for use in low and high pressure hydraulic systems
-
Recommended for gear, vane and piston pumps in hydraulic applications
