流體污染控制：需要了解的內(nèi)容
超過 70% 的系統(tǒng)故障是由流體中的污染物引起的。即使沒有立即出現(xiàn)明顯的故障，也可能會出現(xiàn)高污染水平，并在眨眼間急劇降低液壓控制。
污染被定義為制造設(shè)備中的任何異物并損害其性能。
污染可能以以下形式存在：
? 固體
? 液體（例如水）
? 氣態(tài)（例如空氣）
? 凝膠狀（即像清漆一樣的油降解）
Over 70% of all system failures are caused by contaminants in the fluid. Even when no immediate failures are apparent, high contamination levels can be present and sharply decrease hydraulic controls in the blink of an eye.
Contamination is defined as any substance foreign to the manufacturing equipment and damaging to its performance.
Contamination can exist as:
? solid
? liquid (i.e. water)
? gaseous (i.e. air)
? gel-like (i.e. oil degradation like varnish)
Watch on Tencent “Fluid Contamination Control: What You Need To Know”.
固體污染會導(dǎo)致密封表面和表面磨損，從而導(dǎo)致外部空氣和濕氣進(jìn)入泄漏點，還可能導(dǎo)致摩擦引起的局部熱降解。
固體污染物通常稱為顆粒污染物，有各種尺寸和形狀，通常會磨損液壓系統(tǒng)中的主要部件。
在這種磨料質(zhì)量下，高污染物水平會加速部件磨損并縮短液壓供給和使用壽命。
磨損的部件反過來會導(dǎo)致：
? 液壓機(jī)械運行效率低下
? 液壓部件卡死（如液壓泵、液壓缸、液壓馬達(dá)）
? 更高的流體溫度
? 泄漏
? 失控
Solid contamination can lead to worn sealing surfaces and surfaces that cause leaking points for external air and moisture ingression and can also lead to friction-induced localized thermal degradation.
Solid contamination, generally referred to as particulate contamination, comes in all sizes and shapes and is normally abrasive to major components in the hydraulic system.
With this abrasive quality, a high contaminant level accelerates component wear and decreases the hydraulic supply and service life.
Worn components, in turn, contribute to:
? Inefficient hydraulic machine operation
? Seizure of hydraulic parts (such as hydraulic pumps, cylinders, and hydraulic motors)
? Higher fluid temperatures
? Leakage
? Loss of control
所有這些現(xiàn)象都是污染物和機(jī)器部件之間直接機(jī)械作用的結(jié)果。
除固體污染外，還有三 (3) 種其他類型的污染物會造成流體污染。分別是：
? 液體污染會加速液體老化過程和漆膜的生成，或?qū)е陆饘俨考霈F(xiàn)腐蝕點蝕，從而在內(nèi)部產(chǎn)生固體金屬顆粒污染。
? 氣體污染會引起空化和柴油效應(yīng)，從而可能導(dǎo)致顆粒污染和局部熱降解。
? 凝膠狀污染可能是加速老化、潤滑性能改變和不足導(dǎo)致顆粒生成增加以及化學(xué)反應(yīng)形成水的根本原因。
污染物還可以充當(dāng)催化劑，加速流體的氧化并刺激其成分的化學(xué)分解。
All these phenomena are a result of direct mechanical action between contaminants and machine components.
Aside from solid contamination, there are three (3) other types of contaminates responsible for fluid contamination. They are:
? Liquid contamination can accelerate the fluid aging process and generation of varnish or cause corrosive pitting of metallic components and therefore internally generate solid metallic particle contamination.
? Gaseous contamination can cause cavitation and dieseling effects which may lead to particle contamination and local thermal degradation.
? Gel-like contamination can be a root cause of accelerated aging, increased particle generation via changing and inadequate lubrication properties, as well as the formation of water from chemical reactions.
Contamination can also act as a catalyst to accelerate oxidation of the fluid and spur the chemical breakdown of its constituents.
什么是液壓和潤滑油過濾？
What is Hydraulic and Lube Filtration?
液壓和潤滑油過濾是解決污染物問題的優(yōu)質(zhì)選擇。
Hydraulic and Lube Filtration is the perfect candidate for combatting issues with contaminates.
通過對工作液采用過濾技術(shù)，它將去除上述許多污染物并延長系統(tǒng)組件（也在上面提到）的使用壽命。
過濾組的作用是確保油品保持性能。
過濾過程有助于去除油系統(tǒng)中的污染物并持續(xù)調(diào)節(jié)流體。它還確保油的粘度特性在所需的溫度范圍內(nèi)保持恒定。
By utilizing filter technology for your operating fluid, it will remove many of the contaminates mentioned above and extend the life of the system components (also mentioned above).
Filtration groups, such as the ones shown in the photo located at the top of this page, do the job of making sure oil properties remain at their best.
The filtration process helps remove contamination from oil systems and conditions the fluid on a continuous basis. It also ensures the oil viscosity properties remain constant per the desired temperature ranges.
