How should the hydraulic oil of a four-column hydraulic press be maintained?

The maintenance of the hydraulic oil of the hydraulic press is very important for the operation of the equipment. Among them, there are many requirements for the characteristics of hydraulic oil. Must strictly comply with the standard, such hydraulic oil can bring lasting power to the equipment.

1. The hydraulic oil is filtered by a precision filter element, so that the pollution degree of the oil can be kept at NAS <8 for a long time. The filter element provided with the equipment usually cannot meet the requirements and cannot guarantee the cleanliness of the hydraulic oil, because the dirty capacity of the hydraulic press is only 5um. Generally, the accuracy of the built-in filter element is much greater than 5um. From a scientific point of view, it is required to control the pollution level of general hydraulic stations to be 8 levels below NAS level. For equipment with servo mechanism, the pollution level should be higher than level 7.

2. Centrifugal dehydration/vacuum dehydration (gas station for humidification). As long as it is properly controlled, generally better brands, such as MOBIL, SHELL, etc., can be used for 5 years, and there are more fake oils.

3. Regular oil test: hydraulic oil is widely used, and it is the most used product in industrial oil. Nowadays, the development trend of hydraulic components is small size, high power, and the pressure that the system can provide is gradually increasing.

4. Make sure not to use hydraulic oil at high temperatures, because hydraulic oil will quickly deteriorate at high temperatures.

5. The air filter on the hydraulic station should use a filter that can filter particles and moisture at the same time. It is sold in the market.

One of the important characteristics of hydraulic oil is its low temperature, which requires equipment to be easier to start in a low temperature environment, power transmission is sensitive, hydraulic oil replacement cycle is long, and hydraulic oil replacement cycle is longer, hydraulic oil also has great performance on cleanliness Claim.
