美孚拉瑪500系列防銹潤滑油
Mobilarma 522 ，Mobilarma 524，Mobilarma 525
產(chǎn)品描述
美孚拉瑪500系列潤滑油是優(yōu)質(zhì)性能的產(chǎn)品，主要用于運(yùn)行或?qū)櫥?，并提供有效的防銹膜對機(jī)械內(nèi)部表面。他們特別適合在柴油和汽油發(fā)動機(jī)的潤滑油中運(yùn)行。油驅(qū)水從金屬表面形成強(qiáng)的防水膜，在金屬表面，防止生銹和腐蝕。在拉瑪系列油吸收水系統(tǒng)成油包水乳液使接觸表面的機(jī)械仍然得到良好的潤滑。其良好的化學(xué)穩(wěn)定性和耐磨性和洗滌劑的性能使它們適合作為高質(zhì)量潤滑油水平短期。
在大多數(shù)應(yīng)用中，當(dāng)裝配有潤滑油或液壓油，并在維修中重新安裝時，不必沖走殘留的防銹膜。然而，一個負(fù)責(zé)潤滑油去除拉瑪產(chǎn)品或其殘膜沖洗，建議如果：
1。在拉瑪不提供所需的潤滑特性操作設(shè)備在額定負(fù)載和溫度
2。設(shè)備的排水的拉瑪不能和可觀的口袋容易去除
三.由拉瑪?shù)南到y(tǒng)油液的污染可降低潤滑性能特點(diǎn)（例如；拉瑪能增加氟利昂云點(diǎn)的油包水減少壓縮機(jī)或高壓液壓系統(tǒng)的抗磨特性）
4。防銹劑的存在降低了新的石油的能力，在渦輪機(jī)和類似的設(shè)備分開的水。

Mobilarma 500 Series
Rust Protection Lubricants
Product Description
Mobilarma 500 Series oils are premium performance products primarily intended as run-in or lay-up lubricants, which provide effective rust preventive films on the internal surfaces of machinery. They are particularly suitable as run-in lubricants for diesel and gasoline engines. The oils displace water from metal surfaces and form strong water-resistant films on the metal surfaces to prevent rust and corrosion. The Mobilarma Series oils absorb the water in systems into a water-in-oil emulsion so that the contact surfaces of the machinery still get satisfactory lubrication. Their high level of chemical stability and their anti-wear and detergent properties make them suitable as high quality short-term lubricants.
In most applications, the residual rust preventive films need not be flushed away when the assembly is filled with lubricating oil or hydraulic fluid and put back in service. However, flushing with a charge of lubricating oil to remove the Mobilarma product or its residual film, is recommended if:
1. The Mobilarma does not provide the required lubricant characteristics to operate the equipment at rated loads and temperatures
2. Draining of the equipment is difficult and considerable pockets of the Mobilarma cannot be easily removed
3. Contamination of the system oil by the Mobilarma could reduce the lubrication performance characteristics (examples; Mobilarma could increase Freon cloud points in compressors or water-in-oil emulsions reduce anti-wear characteristics in high pressure hydraulic systems)
4. Presence of the rust preventive agents reduces the ability of the new oil to separate water in turbine and similar equipment.
Features and Benefits
The Mobilarma 500 Series oils provide an excellent lubricant that also acts as a rust preventive. This allows safe lay-up of equipment that will not be used immediately but may be operated intermittently at low to moderate loads for short periods of time. These products provide excellent rust preventive performance reducing any potential damage that could otherwise occur in non-operating equipment. This saves clean-up and potential rigorous flushing procedures prior to placing the equipment back in service.
