Misunderstanding 1: Selecting a high-precision oil-absorbing oil filter can effectively protect the pump and ensure the cleanliness of the system.
Since the contamination of the hydraulic oil will aggravate the wear of the pump and affect the service performance and life of the pump, large particles of impurities will also jam the pump, seriously affecting the safety and reliability of the system. Therefore, some engineers have chosen a high-precision oil suction filter, which is considered to protect the pump and ensure the cleanliness of the system. However, the high-precision oil suction filter is easy to block due to excessive pollutants, resulting in poor pumping of the pump, resulting in fine air, accelerating the wear of the pump, seriously affecting the safety of the system, so the pressure drop of the oil suction filter should be strictly controlled. A typical hydraulic system can be fitted with a Durable Hydraulic Oil Filter to protect the pump and a filter installed in front of the contaminant sensitive components to control the effects of particle contaminant alignment.

Misunderstanding 2: The rated flow of the filter is the actual flow of the system.
The nominal flow rate of the filter is the flow rate through which the oil filter passes the clean filter element at the specified initial resistance when the viscosity of the oil is 3 Cst. However, in practical applications, the viscosity of the oil changes at any time due to the difference in temperature between the medium and the system. If the filter is buying according to the rated flow rate and the actual flow rate 1:1, when the viscosity of the system is slightly larger, the resistance of the oil passing through the filter will increase, and even the filter of the filter will block the signal of the transmitter, and the filter element is considered to be blocked. . Secondly, the filter element of the filter belongs to the wearing part, and it is gradually polluted during the work. The effective effective filtering area of the filter material is continuously reduced, and the resistance of the oil passing through the filter is quickly reduced to the pollution area. The resistance of the oil passing through the filter is very high. The pollution is blocked by the transmitter, so the filter needs to be cleaned or replaced frequently, which increases the cost of use.
Misunderstanding 3: The higher the accuracy of the oil filter selection, the better.
Solid contamination in hydraulic systems is the main cause of hydraulic system failure, so high-precision filters are used to control pollution. In fact, this will not only increase the manufacturing cost of the system, but also shorten the service life of the filter. How to properly select the accuracy of the filter is mainly determined by the pollution requirements of the main components of the hydraulic system to the oil. The higher the cleanliness of the components, the higher the accuracy of the filter selection. When the wear particles enter the moving gap of the component, a chain reaction of wear occurs. Therefore, to minimize wear and maximize component life, it is necessary to filter out particles of similar size to the gap.
Misunderstanding 4: A filter cartridge with a filtering accuracy that filters out all particles larger than their accuracy.
Contaminants from hydraulic oil can aggravate the wear of the pump and affect the performance and life of the pump. At the same time, if it enters the air, it will also pollute the oil. This can be installed with a Deep Filtration Air Filter Cartridge, filtered air containing pollutants. In addition, in order to prevent component wear or external intrusion in the most effective interception circuit, it is recommended to install a return filter to control the cleanliness of the whole system, and thoroughly clean the pipeline and fuel tank before the system is operated to protect the oil. Liquid contamination. Thus the oil contamination of the entire system is basically controlled.
The above is a misunderstanding about the selection of oil filter. I believe that after reading these, everyone has a certain understanding of the selection.
