Replacement filter element is suitable for Donaldson P167181，HYDRAULIC FILTER, CARTRIDGE （45 * 114， 10 micron， glass fiber）

Détails du produit

Within a hydraulic system, there are typically three locations where filters are located: suction line, return line and pressure line. Suction line filters remove the large particles that often appear within the hydraulic fluid reservoir and are also known as safety filters.

Oil suction filter element

The oil suction filter element is installed on the suction pipeline of the pump to filter the residue in the oil tank and the dirt entering the oil tank through the air inlet. It protects the pump. In order to avoid cavitation of the oil pump, to ensure that the resistance of the filter element is small, generally use 100-200 mesh or finer metal wire woven mesh or notch metal wire material to wind the filter element, which does not play a role in controlling micro-particle pollution in the system

Return oil filter element

The return oil filter element is set on the return oil pipeline of the system. Its function is to filter the newly generated or external invasion dirt in the system before returning to the tank. Therefore, it is the most effective place to control the pollution degree of the system. Although it is in low pressure pipeline, pulsation or pressure impact may also occur according to the operation condition of the transmission device, so the requirements for the filter element should also be in strict accordance with the seven standards.

High-pressure pipeline filter element

The filter element of the high-pressure pipeline filter is installed on the pump outlet pipe to filter the dirt in the oil at the suction inlet, protect the system cleanliness, and maintain a constant pollution level of the system. Due to the high pressure pulsation and pressure impact, the strength of the filter element should meet the ISO3724 test requirements.

For hydraulic parts that are particularly sensitive to pollutants, such as slide valves, servo valves, etc., to avoid pollution, such high-precision filters and filter elements must be installed in the front of the system β The particle size should be small, the ratio should be greater than or equal to 75, and the selection of filter material should also be careful. In addition to meeting the seven safety standards, the filter element should be clean and free of fiber shedding.
