First of all, hydraulic oil is an important part of the hydraulic system. It not only transmits power, but also lubricates and cleans hydraulic components. It is very important to maintain the hydraulic oil, but the choice of hydraulic oil filter should not be careless. So how do you choose the best filter element for your system?
1. Material of hydraulic oil filter element
The material of the hydraulic oil filter element, which is used to manufacture the hydraulic oil filter element, varies according to the cost.
Metallic materials are also quite effective, but cannot be used with all types of elements because some hydraulic fluids are not compatible with certain metals.
Cellulose or filter paper can also be used as a hydraulic oil filter, but it has a short lifespan and therefore requires frequent replacement.
Fiberglass media is very common, but they are more effective in depth filter elements, and although more expensive than paper, fiberglass media is the best choice and does not require frequent replacement.
2. Differential pressure
A drop in pressure in a hydraulic system can affect performance and production capacity, this is especially important if you are considering switching from another material type to fiberglass material, also consider if the drop in pressure will result in an adjustment to the pressure relief valve , causing pressure to build up elsewhere. Options for hydraulic fluid filters go beyond material type and construction, as there are still rating and specification issues.
3. The flow rate and operating pressure of the hydraulic oil filter element
If the flow rate of the hydraulic oil filter element is too fast, it will not be able to effectively remove pollutants. If the flow rate is too slow, the hydraulic filter element may be quickly blocked. The working pressure must be within the range that the system can bear!
The components of the hydraulic system are all precision-machined, and they have high requirements for the maintenance of the hydraulic system, so it is very important to choose the most suitable filter element!
