According to the working environment and working conditions, the selection of hydraulic oil should be comprehensively considered and judged from the aspects of working pressure, temperature, working environment, hydraulic system and component structure and material, economy, etc. when selecting hydraulic oil used in hydraulic equipment. .
Environmental factors include: above ground, underground, indoor, wild, coastal, cold, high temperature, open flame. Operating conditions: pump type, pressure, temperature, material, sealing material, running time.
Oil properties: physical and chemical properties. Economical: use time, oil change period, price.
The circulating hydraulic oil is made of a neutral base oil with a high depth of refining, plus anti-oxidation and anti-rust additives. According to the 40 ° C kinematic viscosity can be divided into 32, 46, 68.
Uses: Circulating hydraulic oil is mainly used for lubrication of bearing housings, low-pressure circulation systems or similar mechanical equipment circulation systems of various types of machine tools with ambient temperature above O °C.
It can be used more than twice as long as mechanical oil. This product has good rubber sealing adaptability and its maximum operating temperature is 80 °C.
Quality requirements:
(1) Appropriate viscosity and good viscosity-temperature properties. It is required that the viscosity of the oil is less affected by the temperature change, that is, the temperature change does not affect the normal operation of the hydraulic system.
(2) It has good rust resistance and oxidation stability.
(3) It has ideal air release value, anti-foaming property, water separation and rubber sealing adaptability.
Precautions
(l) Thoroughly clean the original hydraulic tank before use to remove residual oil, waste oil and sediment, and avoid mixing rabbits with other oils.
(2) This product is not suitable for special machine tools with harsh working conditions and high lubrication requirements. For gear transmissions, hydraulic systems and guide rails with high requirements on oil quality, medium and heavy duty gear oil, anti-wear hydraulic oil or high-grade hydraulic oil should be used.
Precautions for use:
(1) Thoroughly clean the original hydraulic oil tank before use to remove residual oil, waste oil and sediment, and avoid mixing rabbits with other oils.
(2) This product is not suitable for special machine tools with harsh working conditions and high lubrication requirements. For gear transmissions, hydraulic systems and guide rails with high requirements on oil quality, medium and heavy duty gear oil, anti-wear hydraulic oil or high-grade hydraulic oil should be used.
(3) This oil replaces mechanical oil for the lubrication of the circulation system of general machine tools and other similar mechanical equipments, with significant economic benefits, can extend the oil change interval, and saves oil by an average of 1/3-1/2.
