Filter element classification

What are the main classifications and uses of oil filters

According to the installation position in the hydraulic system, the hydraulic oil filter is divided into suction oil filter, pressure pipeline oil filter and return oil pipe

Road oil filter element.

Suction pipe hydraulic oil filter: suction pipe (oil tank - hydraulic pump inlet) or directly install the oil filter in the oil tank

It is a necessary measure to protect the hydraulic pump, and its accuracy is generally 100 ~ 180μm, depending on the self-priming capacity of the pump

Excessive flow resistance leads to cavitation of hydraulic pump.

Pressure pipeline hydraulic oil filter: The pressure pipeline oil filter is not only to protect its downstream components, but also to ensure the system oil

Pollution of the main oil filter, through its own efficient purification of the oil, the hydraulic pump also plays a good protective role, filter fine

The degree is 5-10 μm, the pressure of the filter is large, the vibration is also very important, and the allowable pressure difference of the oil filter element of the pressure pipeline is different according to the pressure

The force level ranges from 0.3 to 0.7MPa. As a pressure pipeline oil filter for ground equipment, comprehensive consideration of cost, installation space, can

Big is big.

The hydraulic oil filter element of the oil return pipe: the abrasive particles and other dirt generated by various components during the working process can be set back

The oil in the pipeline is filtered and blocked to avoid returning to the tank and being inhaled by the hydraulic pump again. Allowable differential pressure of oil filter in return line, root

According to different pressure levels, the range is 0.3 ~ 0.5MPa. The accuracy is determined according to the requirements of oil pollution. Return line oil filter

There are more factors to consider in the setting, one of the important factors is the hydraulic shock, especially the upstream hydraulic cylinder and proportion

In the case of the valve, the reversing of the hydraulic cylinder and the sudden power loss of the proportional valve under high pressure will produce a large instantaneous flow impact.

It will cause great damage to the filter element of the oil filter, and it is necessary to have a full understanding of the design and selection of the oil filter of the return pipeline

To strengthen. Mainly suitable for petrochemical industry, oil field pipeline filtration; Fuel oil filtration for refueling equipment and construction machinery equipment; Water treatment

Industry equipment filtration; Pharmaceutical and food processing fields.
