Pit avoidance guide: What do you need to pay attention to when choosing an oil purifier?

70% of the failure in the hydraulic system is caused by the pollution of the oil, even if the online oil filter is installed in the hydraulic system, it can not

 completely guarantee that the oil will not be contaminated, the oil purifier independently developed by Lifeert is to purify the oil deeply.

The application of oil purifier is very extensive, the right oil purifier needs to be used in the right working conditions, the oil purifier is deeply concern

ed, the following is an introduction to the oil purifier selection needs to pay attention to:

Q: How to choose according to the type of oil?

1. Whether the oil is corrosive, corrosive selection needs to pay attention to the material of the filter element, can not directly use carbon steel, need 

stainless steel or carbon steel rubber lining treatment, all seals can not use commonly used nitrile rubber, need to choose fluoroelastomer and other 

corrosion-resistant materials.

2. If the viscosity of the oil is too high, it is necessary to consider using a high-viscosity pump and consider whether it needs to be added to the 

heating system.

3. Whether the oil is flammable and explosive, if flammable and explosive electrical components need to be used explosion-proof.

Q: How to select according to the contaminants filtered out of oil?

1. If it is only ordinary hydraulic oil or lubricating oil, just filter out solid particle impurities in the oil, and choose ordinary LYC-A or LYC-B series oil 

purifier.

2. If impurity removal and dehydration treatment are required, see what requirements should be met after filtration, and then determine whether to 

choose a vacuum oil filter machine or a coalescence dehydration oil filter machine.

3. If the accuracy after filtration is very high, it is necessary to reach NAS1638 3-6 level, and you need to choose a 3R ultra-precision oil purifier. If it 

is necessary to reduce the acid value and improve the resistivity, a regeneration oil filter machine is selected.

Q: How to choose according to the site working conditions?

1. It takes an hour to determine the flow rate of the oil purifier on site, and the flow selection of the oil purifier follows the principle of choosing 

large rather than small.

2. The temperature of the on-site working conditions, see whether the oil is cooled or heated first, whether explosion-proof treatment is required, 

EX II BT4 explosion-proof grade or EX II CT4 explosion-proof grade.

3. Is the field device indoors or outdoors? Outdoor recommended to use the box type. The power supply voltage of the site, whether the oil purifier 

needs to move, how many meters the head reaches and the caliber size of the oil inlet and outlet.

In short, users should choose the right oil purifier according to actual needs, more oil purifier selection methods and suggestions, please leave us a
