What role do they play in a construction machine?
No one needs to be convinced of the enormous impact on the efficiency and reliability of a construction machine that effective filtration has. Meanwhile, many owners routinely trivialize the need for regular replacement of hydraulic filters.
This, in turn, can lead to serious problems, including costly system failure. This can be avoided by using properly selected filters and adhering to the manufacturer's recommended replacement intervals.
Can't move without filters
Hydraulic filters are used in the systems of all machines, regardless of their size. Their role is to capture even small impurities, which would otherwise circulate in the hydraulic system, leading to accelerated wear of its individual elements, a decrease in efficiency, and even leading to failure. Timely replacement of filters is always much cheaper than complicated repair.
What's more. It should be remembered that machine manufacturers and parts suppliers condition the recognition of the warranty on whether the machine was properly serviced. This also applies to the required frequency of hydraulic filter replacement.
Therefore, it is worth sensitizing the operator or fleet manager to attach great importance to checking the level and condition of filtration in the machine. This standard operating activity can save the owner from very high costs.
The difficult art of selecting hydraulic filters
We distinguish many types of hydraulic filters, including suction, return, pressure, filler. We also divide these elements according to operating parameters, such as the method of trapping impurities (mechanical and forceful), filtration accuracy, permissible pressure value, and the place of deposition of impurities (surface and deep).
The key to effective filtration is, of course, the correct selection of filters for a specific machine. Here, at least several factors should be taken into account, such as: the type and amount of oil, the place of installation (different filters are used, for example, behind the pump, different in front of the pump), working conditions, pressure or manufacturer's guidelines.
Since selecting filters for a machine is not such a simple matter, it is always recommended to entrust this to a specialized service. Wibako experts base on many years of experience and technical knowledge, thanks to which we are able to accurately indicate the appropriate filters and of course replace them in accordance with the machine manufacturer's recommendations.
Good to know!
When selecting hydraulic filters, many consequential mistakes can be made. The most common ones include mismatching the element to the pressure in the system and to the specific type of oil.
Original hydraulic filters are the best choice
At Wibako, we always recommend machine owners to invest in original hydraulic filters. These are not so costly elements to risk buying the cheapest substitutes of unknown origin.
In case the owner decides to use substitutes, they should be filters from a reputable manufacturer. It is required to perfectly match them to the machine and for them to have exactly the same parameters as the original filters.
It is also very important to replace the complete set of filters, not just those that seem to be the most contaminated.
Let's also remember that the basic parameters determining the quality of filters are: the filtration coefficient (size and amount of impurities retained by the filter) and efficiency. We recommend choosing filters equipped with contamination indicators - this facilitates ongoing control of filtration effectiveness and timely planning of replacement.
