MOV Long Life润滑脂---核应用产品
MOV Long Life使用的增稠剂结合水处理的第二基础油以表现突出的状态。它的专门特殊配方为手动和电动操作阀门执行器提供了的润滑方案，解决了过去不能解决的问题，并提供一个更为长效的服务。该润滑脂已经证明了其*性能可以替换已经停止使用的埃克森Nebula EP™。MOV Long Life润滑脂已达到或超过了用户在电动阀箱、限位开关箱、回转齿轮箱、阀门、阀杆螺母的润滑等方面的期望。多年来的业务评估和记录已经证明了MOV Long Life产品，并被各地广泛使用在各种类型的阀门执行器，核电站和燃料电站。
MOV Long Life与Nebula EP润滑脂和钙复合增稠剂是可以兼容的，也用于没有剥落的老化油脂的操作杆或没有*清洁油脂的阀杆。润滑不当会导致昂贵的后果和损失，包括失去设计性能、过早磨损齿轮和阀杆螺母等方面。
已经被Limitorque™批准，用于主齿轮箱的安全电动阀门执行机构。

MOV Long Life greases tested by the Electric Power Research Institute (EPRI) for high temperature MOV's and for bearings in Lube Notes for December 2006. Both did very well in comparison to the alternatives, especially when all the characteristics were considered.
Note Number 1, High Temperature Grease Evaluation: "The MOV LL result at the stem nut temperature of 85°C (185°F) warrants consideration in future testing. Not only does it appear that it will retain oil better, but it also has better oxidation stability and consistency retention (remaining a grade 2) than the other lubricants evaluated."
Note Number 3, Comparison of Roller Bearing Greases: "We believe that MOV LL will prove to be superior in antirust based on other, more rigorous tests. This feature is important in areas of high humidity near an ocean. Given that a bearing failure occurred due to a weld seize, there is a comfort in choosing MOV LL that has a significantly higher weld point and load-carrying ability."
MOV LONG LIFE PASSES SEVERE CORROSION
TESTING ON STRESSED SAMPLES FROM
ENVIRONMENTAL QUALIFICATION
The Candu Owners Group had Environmentally Qualified MOV Long Life for use in the
Limitorque main gearbox applications. Samples had been subjected to the following;
• oven aging at 130°C (266°F) for 660 hours;
• gamma irradiation to 70 Mrad; and
• Loss of Coolant Accident (LOCA) steam exposure including 6 hours
exposure to 171°C (340°F) and 105kPa (15 psi) steam.
COG testing had shown that the lubrication characteristics of MOV Long Life remained
excellent so the purpose of this testing was to show that the calcium sulphonate
thickener would continue to provide corrosion protection for the main gearbox and for
limit switch gearbox applications. Samples of the EQ’d grease were tested at an
independent lab according to ASTM D-130.

Comments: After five years aging, irradiation and exposure to steam MOV Long Life still
provided excellent corrosion protect, even after four times the normal test time. Note
that Nebula did not even survive the five year aging without excessive hardening.
