Hydraulic oil filtration scheme for construction machinery manufacturing

―Equipment selection: pressure pipeline filter

Foreword:

The hydraulic system of shovel transport machinery, road machinery, piling machinery, special vehicles, engineering hoisting machinery, concrete machinery, sanitation machinery, military engineering machinery and other machinery will have oil pollution during operation. Whether the hydraulic oil is clean or not will not only affect the working performance of the hydraulic system and the service life of hydraulic components, but also directly affect the normal operation of the vehicle. At least 75% of hydraulic system failures are caused by unclean hydraulic oil. Therefore, it is very important to prevent hydraulic oil pollution.

The main sources of impurities in the hydraulic system are:

1. Mechanical impurities remaining in the hydraulic system after cleaning, such as water rust, casting sand, welding slag, iron filings, paint, paint skin and cotton yarn filings.

2. Impurities entering the hydraulic system from the outside, such as dust entering through the oil filler and dust ring.

3. Impurities generated in the working process, such as fragments formed by the hydraulic action of the seal, metal powder generated by relative wear due to movement, colloid, asphaltene and carbon slag produced by oxidation and deterioration of the oil, etc.

How to select hydraulic oil filter

(1) When selecting the hydraulic oil filter, the model of the filter can be selected according to the characteristics of the above filters, combined with the requirements of various typical hydraulic components and systems for pollution level or filtering accuracy, and the working pressure, oil temperature and oil viscosity of the system.

(2) The hydraulic oil filter shall have sufficient flow capacity, which refers to the maximum flow allowed to pass through the filter under - constant pressure drop. It shall be selected according to the filter sample in combination with the installation position of the filter in the system.

(3) The hydraulic oil filter shall have certain mechanical strength and shall not be damaged by hydraulic pressure.

(4) For the hydraulic system that cannot be shut down, the filter with switching structure must be selected. The filter element can be replaced without shutdown.

Equipment recommendation

PLF pressure line filter

PLF pressure line filter

Overview:this series of filters can be installed on pressure pipelines with different pressure levels to further remove or block the wear of components brought in by the boundary and the impurities produced by the chemical action of the medium itself.

Application:petroleum, chemical plant, steel plant, printing and dyeing plant, power plant, construction machinery parts, agricultural machinery parts, hydraulic machinery parts, coal mine, shipbuilding and other industrial fields.
