Shell Clavus Oils are highly refined high quality naphthenic minaral oils with excellent low temperature properties, especially select ed for use in refrigerator compressors.

壳牌奇伟士系列润滑油采用高度精炼的优质环烷基矿物基础油调制而成，具有良好的低温性能，特别适用于制冷压缩机的润滑。

Application Shell Clavus Oils are high quality, hydrotreated naphthenic mineral oils without additives. Specially suited for the efficient lubrication fo refrigeration compressors.

用途 Shell&奇伟士&润滑油是由优质氢化加工的纯环烷基础油配制而成，是专为润滑制冷压缩机而研制。

It can also be used when hydrocarbon (R600) is the refrigerant. It may be used with halogenated hydrocarbon (R12, R22) if Shell Clavus Oils G is not available.

在缺乏Shell&奇伟士&G润滑油的情形下，Shell&奇伟士&润滑油也可应用作卤代烃（R12，R22）为冷冻剂的制冷压缩机。

The structure character and operating principle of centrifugal compressor are introduced, which show that the rotor of compressor is trend to be damageable comparing to other components.

介绍了离心式压缩机的结构特征与工作原理，由此得出转子故障是主要故障形式，从而对其重点研究。

In fact, many car brochures, have introduced the fogging of the method is transferred to the air-conditioning vent Windshield block, open the air conditioner switch, so that compressors work in order to dehumidify.

其实很多汽车的说明书中，都介绍了除雾的方法，就是将空调风口调到风窗挡，打开空调开关，让压缩机工作，以便除湿。

Flexicat yellow/blue catalyst produced by CRI was the fourth dehydrogenization catalyst which was used in Daqing 60KTA styrene equipment. We have taken effective ways and means to prolong the validity-period of the catalyst, including improving in-let temperature, adjusting the radio of steam/ethylbenzen, optimizing the operation of compressor etc.

CRI公司的Flexicat yellow/blue催化剂是大庆石化苯乙烯装置应用的第四批乙苯脱氮催化剂，在延长期采取了合理提高入口温度、合理匹配稀释蒸汽的用量、加强尾气压缩机的操作等有效的操作方法，使该催化剂从装填到卸载共运行了35个月，共生产苯乙烯210913吨，使用周期增加46%，增加经济效益1.5亿元。

It has been widely used on the free operating of air presser, city automatic water supply and sewage system, and other automatic machines, whose motors have to be protected. Also it can be used dependently as the protective accessories when starting the motors.

被广泛应用于空气压缩机的自动运行、城市的自动供水及排污和其它需要对电机实施保护的自动化设备上；也可单独应用于电动设备上作为电机的启动保护部件。

Safety features include high and low-pressure refrigerant controls to protect the compressor hot water high-limit desuperheater pump shutdown.
