Key points of rational use of hydraulic oil

After the working medium is selected, if it is used improperly, it will cause the hydraulic system to work improperly due to the change in the nature of the liquid.
① It is necessary to verify the variety and brand of the oil (the comparison between the factory test list and the technical documents should be consistent).
② The new oil must be filtered before use (due to possible pollution during refining, packaging, transportation and storage, the new oil is not clean; The cleanliness of the new oil should be 1 to 2 levels higher than the cleanliness allowed by the system).

③ The hydraulic system should be thoroughly cleaned before injection.
④ The oil must generally be used alone and cannot be mixed at will.
⑤Strict pollution control (pay special attention to prevent solid particles, water, air and various chemicals from invading the hydraulic system).

⑥In the process of working liquid storage, handling and filling, as well as the design and manufacturing process of the hydraulic system, certain protective and filtration measures should be taken to prevent the oil from being polluted, so that the cleanliness of the medium meets the relevant regulations. The hydraulic working medium should be stored in a clean place, and the utensils used should be kept clean; It is best to use silk or chemical fiber fabric to scrub the components, so as not to block the small pores of the components, causing failure, the fuel tank should be sealed, and the filter element of the filter should be regularly checked and cleaned and replaced.

⑦Pay attention to safety, oil should pay attention to fire prevention; The phosphate solution should not touch human skin.

⑧ Pay attention to the impact of changes in working conditions on its performance. Some of the main performance parameters of the medium should be tested regularly and regularly with reference to the relevant standards. When the hydraulic medium in operation deteriorates and exceeds the specified technical requirements (oil change index), the working medium should be replaced in time.
⑨ The amount of oil added to the system should reach the highest oil marking position of the tank. Correct refueling method: first add to the highest oil marking line, start the hydraulic pump, so that the oil is supplied to the pipelines; Then fuel to the oil tank oil line, and then start the hydraulic pump, so many times until the oil remains near the oil line.

⑩Pay attention to the effect of high and low temperature environment on the performance of hydraulic oil.
