REQUIRED QUALITIES OF A GOOD HYDRAULIC FLUID (DESIRABLE PROPERTIES OF HYDRAULIC FLUID) Any good hydraulic fluid should possess the majority of the properties listed in Table 2.4. Table 2.4. Required properties of a good hydraulic fluid 1. Stable viscosity characteristics. 2. Good lubricity. 3. Compatibility with system materials. 4. Stable physical and chemical properties. 5. Good heat dissipation capability. 6. High bulk modulus and degree of incompressibility. 7. Adequate low-temperature properties (such as cloud point, pour point and freezing point). 8. Good flammability characteristics (such as flash and fire points). 9. Low volatility. 10. Good demulsibility. 11. Better fire resistance. 12. Lower foaming* tendency. 13. Nontoxicity. 14. Good oxidation stability. 15. Better rust-and corrosion-preventive qualities. 16. Low density and specific gravity. 17. Low coefficient of expansion. 18. Simple and easy handling. 19. Ready availability. 20. Inexpensive. Since it is impossible for any single hydraulic fluid to provide all these desirable characteristics, therefore the fluid power designer should compromise in some properties so as to select the fluid which provides the overall requirements for a particular application.
