Kakšne učinke ima visoka temperatura na hidravlično olje?

Hydraulic systems also convert energy into heat during operation, and inefficiencies can increase heating of the hydraulic fluid. Efficiency can be reduced when the cylinder is not suitable for the application (for example, a slow-speed jacking cylinder used in a high-repetition, high-duty-cycle application). Normal wear can also lead to increased friction and poor operation, which Zmanjša učinkovitost . Zato dobro zasnovan in dobro vzdrževan hidravlični sistem običajno ne bo pregret ., vendar je nižja učinkovitost in slabši pogoji bo več toplote .

Visoke temperature lahko negativno vplivajo na hidravlične sisteme, ki niso zasnovani za obvladovanje tega . Ta članek uvaja učinke visokih temperatur na hidravlično olje . .

1) Višja toplota je enaka nižja viskoznost olja .

Morda mislite, da je hidravlično olje olje in lahko prenese ekstremne temperature . Konec koncev, motorično olje najdemo v motorjih za notranje zgorevanje in lahko preživi tisoče ur pri visokih temperaturah ., vendar to ni vedno tako, da je Olje, ki je videti, da je Olje, ki je preprost {{2} viscoznosti, s temperaturo {{2} motorično olje. thinner. This is important because hydraulic oil is also responsible for lubrication within the hydraulic system. Oil with lower viscosity has poorer lubrication properties and can no longer protect reciprocating parts to a certain extent. So, the higher the oil temperature, the greater your chances of experiencing accelerated mechanical wear. This means you bo pogosteje zamenjal črpalke in jeklenke .

2) Povečana toplota vodi do povečane oksidacije .

Oxidation is a chemical reaction that occurs when air is present in a hydraulic system. Oxidation is one of the main reasons for reduced stability of hydraulic oil and causes the oil to turn black and become contaminated. The chemical reaction leads to the formation of acids, which increase fluid viscosity and cause corrosion, gumming, varnishing, and slow Operacija . Najslabši del je, da se hitrost te kemične reakcije podvoji za vsakih 10 stopinj poviša temperaturo . Torej, vroča je olje, hitreje pa oksidira .

3) Toplota vpliva na življenjsko dobo hidravličnega olja .

The bottom line is that too much heat can have a significant impact on the life of the hydraulic oil, and poor maintenance can lead to inefficiencies and heat. This has a cascading effect on the entire system. In other words, if you can't repair a component when it starts to get abnormally hot, you may increase wear on other parts of the hydraulic system and you will be replacing more components in kratek čas .
