In this paper, we are going to introduce kubota m7040 and kubota m8030 and racor 120at hydraulic filters from aspects of their advantages and filtering methods.

 

What Is Hydraulic Filter?

 

Hydraulic filter refers to the filter installed in the hydraulic pipeline above, to filter the hydraulic oil mixed with mechanical impurities and chemical changes produced by some impurities, so as to prevent the spool stuck, throttling hole gap and damping hole plug and hydraulic components too fast wear and other faults.

The function of hydraulic filter is to filter various impurities in the hydraulic system. The impurities mainly include mechanical impurities still remaining in the hydraulic system after cleaning such as rust, casting sand, welding slag, scrap iron, paint, paint skin and cotton dust, external impurities entering the hydraulic system like the dust enters through the refueling port and dust ring such as hydraulic fracturing of seals, impurities generated during the working process, metal powder generated by relative wear and tear, colloid, asphaltene, carbon slag and so on caused by oxidation metamorphism of oil.

 

Advantages Of Hydraulic Filters

 

• Filter material should have a certain mechanical strength to ensure that it will not be damaged by liquid pressure under a certain working pressure.
• At a certain working temperature, the performance should be kept stable; It has enough durability.
• Good corrosion resistance.
• Structure as simple as possible, compact size.
• Easy to clean and maintain, easy to replace the filter element.
• Low cost.

 

Advantages And Disadvantages Of Different Filtering Method Of Hydraulic Filters

 

In the design and use of hydraulic system, which or several filtration methods should be used according to the type of hydraulic components, working conditions, cost and other comprehensive consideration. In order to facilitate customer design and convenient use, the advantages and disadvantages of different filtration methods of hydraulic filter are summarized as follows.

 

Pressure oil filtration

 

Advantages

 

• Installed at the pump outlet, directly protect the downstream precision hydraulic components;
• Relatively less sensitive to pressure drop, so the filter volume can be relatively small.

 

Disadvantages

 

• Filtration resistance to high pressure, expensive;
• The pump is not protected;
• Control and execute component wear pollutants directly back to the fuel tank

 

Return oil filtration

 

Advantages

 

• The hydraulic system returns to the oil tank after filtering, and the oil in the tank is clean;
• Low pressure grade, price offset;
• Can be inserted into the fuel tank, saving space.

 

Disadvantages

 

• In the upstream of precision hydraulic components must be separate pressurized oil filter protection;
• Large oil pulsation affects the filtration accuracy and makes the filter easily damaged

 

Oil absorption filtration

 

Advantage

 

Can directly protect the pump.

 

Disadvantage

 

Affected by pump suction, oil suction filter volume is large, filtration accuracy is low.

 

Suction back oil filtration

 

Advantage

 

The return oil is directly sucked away after filtration, with high filter utilization rate, low system cost and good oil absorption effect.

 

Disadvantage

 

Oil circulation, high requirements for system heat dissipation and oil.

 

Bypass filtration

 

Advantages

 

• Independent with the main system, stable flow;
• High precision filtration.

 

Disadvantage

 

High cost.
