the hydraulic oil is the hydraulic medium used in the hydraulic system that uses the hydraulic pressure energy, and plays the role of energy transmission, system lubrication, anti-corrosion, rust prevention, and cooling in the hydraulic system.
For hydraulic oil, first of all, it should meet the requirements of hydraulic device for liquid viscosity at working temperature and starting temperature.
Because the change of oil viscosity is directly related to hydraulic action, transmission efficiency and transmission accuracy, it also requires oil viscosity-temperature performance and Shear stability should meet the various needs of different applications.
There are many types of hydraulic oils, with different classification methods.
For a long time, it has been used to classify hydraulic oils by purpose, and some are classified according to oil type, chemical composition or flammability.
manual busbar bending machine Hydraulic Oil
The No. 46 anti-wear hydraulic oil used in the bus processing machine has outstanding anti-wear performance and anti-rust and anti-corrosion performance, which prolongs the service life of the bus processing machine pump; has good oxidation resistance and prolongs the oil change interval; excellent anti-foaming performance And air release, avoid cavitation and cavitation; good anti-emulsification, can be completely separated from water in a short time; good compatibility with the sealing material, effectively protect the sealing material and prevent leakage. Low-zinc formula, its performance meets or exceeds the hydraulic fluid specifications of the world and the requirements of major hydraulic equipment manufacturers.
The choice of hydraulic oil
manual busbar bending machine of all, is the choice of oil varieties.
When selecting oil types, priority is given to the special hydraulic oil recommended by the product.
This is the key to ensuring the reliability and life of the equipment.
If there is no special hydraulic oil, it can be considered according to factors such as working pressure and temperature range.
After determining the type of hydraulic oil, it is necessary to select the oil viscosity grade (hydraulic oil brand).
The choice of viscosity grade is very important, because viscosity has a significant effect on the stability, reliability, efficiency, temperature rise and wear of the hydraulic system.
The hydraulic oil with high viscosity produces greater resistance when it flows, and consumes more power to overcome the resistance.
The power will be converted into heat and cause the oil temperature to rise; if the viscosity is too low, the leakage will increase and the volumetric efficiency of the system will decrease.
It will also cause the system temperature to rise faster.
Check the level gauge in the fuel tank regularly (every working day) to observe whether the amount of oil needs to be filled with oil.
When the oil is insufficient, please replenish it in time.
The hydraulic oil must be of the specified model. The characteristics of the No. 46 anti-wear hydraulic oil will change every 6 months or after 5000 to 20000 hours of use on the bus bar processing machine, and it will tend to solidify (dense).
Generally, the oil should be changed when it has been used for 5000 hours or the color of the oil turns brown-black.
Evaluation method of hydraulic oil
|Color is transparent or unchanged||good||good||Use|
|Transparent or light color||good||Mixing with other hydraulic oils||Use|
|A little change||good||There are bubbles or water||Water separation|
|Brown Black||not good||Be oxidized or heated||Replace hydraulic fluid|
|Transparent and small black impurities||good||External substance||Use after filtration|
