Besides the appearance, what do grease and oil still have to differ after all?

Adhesiveness lies when attrition place when static condition, grease can maintain his original figure, do not send suffer gravity to make with automatic prediction of a person's luck in a given year, also won't be in perpendicular apparently slide and go from leakage of aperture point drop. This characteristic parks the attrition position of seldom perhaps actuate to stopping, to the position with compensatory grease very difficult material (lubricant place works in sky of overhead traveling crane for example) , and those who open wide type or sealed and bad place is very applicable. Lie when attrition place when athletic condition, grease won't suffer in that way like lube leave the action of mental efforts and swing leakage, also won't splash from sealed and bad place. A few dribble or the phenomenon that splash oil can avoid completely almost, can make sure the environment does not suffer so or get pollution less, also can prevent to pollute a product. This bit to resembling papermaking, knit, the industry such as food especially important. The working temperature limits of grease of use temperature limits should compare lube wide. For example, general lithium base grease can be in - limits of 20~120 ℃ temperature is used, commonly calcium radical or natrium base grease also can be in - 20~60 ℃ or - use below 20~120 ℃ . The temperature range that the lube of one brand uses Dan Mou is narrow much. Compression sex grease in the metal apparently adsorptive ability should compare lube to be gotten greatly much, can form solidder oily film, bear higher working load, because the result of many polarity material is contained inside grease,this is. In addition, regard a foundation as fat it, after adding polarity additive, impressibility also relatively lube is good. When service life grease is used for a long time and changing, still can assure lubricant action, because remove the grease of just nears attrition surface one little part of lubricant action truly, and support black fibrous affects a loop to lubricate, visible service life is quite long; And lube needs to often be added, perhaps offer oil circularly, otherwise unwarrantable machinery lubricates normally. Look from the amount, the cost amount of lube wants much 15~20 than grease times, because this uses grease,lubricant place should compare lube much a lot of. Lubricate like the car place, use grease to occupy 2/3 about strong. On the other hand, because often be not cheered, maintenance period long, use up reduce, upkeep cost also low. The facility construction that lubricant facility construction uses grease to lubricate is simpler, can simplify so design, reduce investment. In addition, of lubricant system cover an area of an area quite small, bit more lubricant setting is very agile, after devoted movement, return OK and managing care and maintenance and overhead expenses. Certain and accurate instrument, appearance and electronic equipment inside dimensional minimum does not allow to establish lubricant system only, need long life often relies on grease even lifelong and lubricant. And lube needs to lubricate in airtight system, lubricates facility construction is more complex also, invest and cover an area of an area very big also, unsuited use in the lubricant place that close partly or does not close. Defend function grease won't get itself weight affect and from defend a surface shed lose automatically, have retain ability, and average fat layer compares oil reservoir again thick, the capability that prevents water or vapor to permeate metallic surface consequently is stronger also, can keep apart acerbity, alkaline, damp, oxygen and water surface of job of direct dip corrode. Some grease still won't be mixed by basic and chemical, organic raw material, fuel lube dissolves. And of lube defend ability compares difference, can have particular safety action inside brief time only. Sealed function grease can prevent dirt enter working surface, avoid foreign matter interfuse, wear away mechanical spare parts. The precision that to be like bearing these dimensional structures compare complex, lubricant face asks to compare high working component, grease can hold back dust impurity in bearing appearance face, and can main interstitial cram, rise to close action. To if certain and coarse machinery is agricultural tractor, mower, bulldozer, whole mechanism is contacted with clay, arenaceous bead, its rotational place uses grease to lubricate, can have lubricant effect not only, and still rise to close on certain level action. But lube does not have this kind of ability. Amortize damping sex because the viscosity of grease is big, oily better, so to certain often ask change movement way is mixed bear the machinery of very big wallop, for example, the lubricant place such as abduct axis, versatile connect, crusher, grease can have certain amortize damping effect. On certain part, wait like positive drive device, grease is returned can bring down noise, but look always, lube is reached in amortize reduce noise respect poorer. CNC Milling CNC Machining
