Mobil Industrial, United States
Refrigeration Oils
The Mobil Gargoyle Arctic SHC™ 200 Series are fully synthetic, superior performance lubricants, specifically designed for use in refrigeration compressors and heat pumps. They are formulated from wax-free, synthesised hydrocarbon polyalphaolefin (PAO) fluids, which have outstanding resistance to thermal/oxidative degradation. With their naturally high shear stable viscosity indexes and low temperature fluidity, they are able to perform in severe service conditions that are beyond the capabilities of many conventional mineral oils. Their solubility and miscibility with commonly used refrigerants is low, resulting in higher film thickness in the presence of refrigerants under pressure. This can help to reduce shaft seal leakage. Their stability and low volatility characteristics reduces the "light end stripping" which can occur with conventional mineral oils. Mobil Gargoyle Arctic SHC 200 Series lubricants may help reduce frictional losses and improve machine operating efficiencies.
Mobil Gargoyle Arctic SHC 200 Series lubricants are recommended for the lubrication of refrigeration compressors operating at very high temperatures, and for systems with very low evaporator temperatures. They are suitable for compressor systems using refrigerants such as ammonia and carbon dioxide. Their low miscibility with carbon dioxide makes them a suitable choice for screw compressors using carbon dioxide. They are compatible with most common refrigerants, except sulphur dioxide, and have been particularly successful in systems using ammonia as the refrigerant. Mobil Gargoyle Arctic SHC 200 Series are fully miscible with most conventional mineral refrigeration oils. Any mixture with mineral oils may detract from the outstanding performance properties of the Mobil synthetic product.
The Mobil Gargoyle Arctic SHC brand of lubricants are recognised and appreciated for their innovation and outstanding performance.
Our work with equipment builders has helped confirm the results from our own laboratory tests showing the exceptional performance of the Mobil Gargoyle Arctic SHC 200 Series lubricants. Not least among the benefits shown in work with OEMs is the superb low temperature capability providing excellent fluidity at low temperatures, as well as the resistance to viscosity loss due to refrigerant absorption under pressure, along with providing excellent bearing film thickness and shaft sealing properties.
By its nature, the PAO base stock used in Mobil Gargoyle Arctic SHC 200 Series oils provides exceptional thermal/oxidative resistance critical for high temperature applications. The narrow molecular weight distribution of the PAO base stocks also minimizes volatility and can help to reduce oil carryover. Mobil Gargoyle Arctic SHC 200 Series oils offer the following features and potential benefits:
Features | Advantages and Potential Benefits |
High oil film thickness in the presence of refrigerant | Improved compressor protection for extended compressor life as well as better shaft sealing, reduced bearing fatigue and less unscheduled downtime |
Excellent thermal/oxidative and chemical stability | Long oil life and reduced frequency of drain intervals and routine maintenance |
Reduced lacquer and deposit formation | |
Low volatility | Viscosity remains consistent with reduced oil consumption |
High Viscosity Index and wax-free | Excellent low temperature fluidity, no waxy deposits and improved evaporator efficiency |
Low traction coefficient | Potential for improved system efficiency and reduced power consumption |
Seal compatibility | Long seal life, reduced shaft seal leakage |
Mobil Gargoyle Arctic SHC 200 Series are fully synthetic lubricants specifically designed for use in refrigeration compressors and heat pumps.
Application Considerations: While Mobil Gargoyle Arctic SHC 200 Series are compatible with mineral oil products, a mixture will detract from their performance. Systems should be thoroughly flushed and cleaned when replacing a mineral product with a Mobil Gargoyle Arctic SHC 200 Series product. In the case of R22 refrigerants, guidance from the supplier of the refrigeration unit must always be sought to ensure compressor operation is suitable for efficient separation of the oil and refrigerant.

隔離變壓器的作用
隔離變壓器起電氣隔離作用——除了可以保護(hù)設(shè)備,還可以保護(hù)人身安全!隔離危險(xiǎn)電壓。避免一些事故的發(fā)生。
(咨詢(xún)朱工:、13305697615)
隔離變壓器輸出輸入電容耦合小,對(duì)由于閃電,放電,電網(wǎng)切換,電機(jī)啟動(dòng)和其它電網(wǎng)燥聲引起的干擾更具有抑制作用,是比較有效的電源噪聲抑制器.從這點(diǎn)看隔離變壓器更具有保護(hù)設(shè)備的作用。
所謂保護(hù)人身安全,即對(duì)操作此設(shè)備的人的一個(gè)保護(hù)。因?yàn)楦綦x變壓器的電動(dòng)勢(shì)是通過(guò)二次感應(yīng)獲得,與一次側(cè)(與大地形成回路)不形成一個(gè)回路,因此不會(huì)造成觸電。
隔離變壓器一般是指1:1的變壓器。由于次級(jí)不和地相連,次級(jí)任一根線與地之間沒(méi)有電位差,減少了各種雜波和干擾,使用安全,常用作維修電源(注意:隔離變壓器的功率一定要大于所維修電器的功率),起保護(hù)、防雷、濾波作用。隔離變壓器主要的作用是將用電設(shè)備和電網(wǎng)隔離開(kāi),用于安全性場(chǎng)合或者抗干擾要求的場(chǎng)合等,用電設(shè)備和電源沒(méi)有直接的電聯(lián)系。
隔離變壓器的一次側(cè)和二次側(cè)兩個(gè)線圈沒(méi)有直接的電氣連接,通過(guò)磁場(chǎng)來(lái)進(jìn)行電-磁-電的轉(zhuǎn)換,這樣一來(lái),就可以通過(guò)一次側(cè)中的三相繞組的三角形接法使一次側(cè)中的奇次諧波在一次側(cè)繞組中形成環(huán)流,不會(huì)流到二次側(cè),這樣電網(wǎng)中的有害諧波將會(huì)減小。一般的調(diào)壓器或是自耦變壓器就不屬于隔離變壓器,因?yàn)槠湟欢蝹?cè)的繞組其實(shí)是連在一起的,只是在一個(gè)繞組上抽頭出來(lái)形成兩個(gè)繞組。
