We know that the four most commonly used testing indexes of hydraulic oil including impurity content, moisture content, viscosity change and total acid value. In other words, as long as the impurity content and moisture content in the hydraulic oil are kept low, and the viscosity and total acid value are changed as little as possible, the life of the hydraulic oil is extended. On the other hand, the hydraulic system runs more smoothly and reduce the wear of precision parts and the probability of hydraulic valve clamp valve to be ensure the normal operation of production equipment. Here we all know that precision filtration is an important link to maintain the four indicators of hydraulic oil, the oil filter on the market is diverse, common pressure, vacuum, centrifugal, coalescent which is different sizes, different functions,.Now let’s discuss how to choose hydraulic oil filtration equipment.
01. filter accuracy
Filter accuracy is the guarantee of filtration quality. If the filtration accuracy of the hydraulic oil cleanliness requirements of the equipment is not good, the filtration will be nothing. The hydraulic oil cleanliness requirements of the equipment are usually indicated in the equipment manual. Just check, and then compare with the accuracy of the oil filter, you can know whether the oil filter meets the requirements. Now NAS, or ISO Code cleanliness grade is mostly popular in the industry, These are the the common hydraulic system requirements of hydraulic oil cleanliness NAS grade:
|
System style |
Oil cleanliness |
Filtering accuracy |
|
High reliability requirements like laboratory and aerospace |
4 |
1-3 |
|
High performance high pressure long life system precision machine tool |
6 |
3-5 |
|
Machine tools with hydraulic system |
7 |
4-6 |
|
Medium pressure, medium vessels for general and engineering systems |
9 |
6-8 |
|
Low pressure or less demanding life of the system |
10 |
7-9 |
|
The low pressure system machine with large gap is generally |
12 |
9-11 |
02. Filtering speed
Filter speed is directly reflected in the production efficiency, good filtration speed reduces the labor, reduces the equipment preparation time, reduce the quantity of oil filter purchase, reduce the comprehensive cost which is cared about when choosing. During filtration, bypass filtration mode can be adopted (suitable for equipment with more oil in a single fuel tank and cannot stop). The specific method is:
The inlet and outlet pipes of the oil filter are put into the same tank (as far as possible);
The filtration time is calculated according to the filtration amount which is calculated more than 10 times the oil in the tank.
For example: the tank has 10 barrels (200 liters), the flow of the filter is 20 liters / minute, the filtration time is at least: 10 barrels 200 liters 10 times 20 liters / minute (filtration speed) 60 minutes = 16.7 hours
03. consumable consumption, energy consumption size
Common consumables including filter element, vacuum oil filter machine and vacuum pump oil, electricity bill, vulnerable parts, etc., which directly affect the cost. The amount of a single filter element is an important index to determine how many impurities can be filtered. The greater ,the better.
04. Easy to use
The oil filter usually needs to walk through the narrow aisles of various equipment, sometimes need to go down to the pit and to be lifted to the top of the oil compressor, so the fuselage must to be as small as possible, lighter weight, easy to move. In addition, the oil filter is required enough safety control device, without manual duty in long time filtration, save manpower.
Winsonda balanced charge type oil filter
Our oil filter meets all above aspects and achieves a high balance of function and cost.
Winsonda oil filter not only removes the impurities and particles in the oil through the balanced charge purification technology, but also purify the acid products, charged colloid, mud, paint film and prevent regeneration, improve the PH value of the oil, reduce the dielectric loss factors and acid value, and improve the oil index.
The balanced charge oil filter can remove sub-micron pollutants with the minimum filter particles 0.1 μm, and the filtration accuracy can reach NAS level 4 or ISO CODE 15 / 13 / 10. Not affected by the particle size of pollutants (metal, dust, rubber, etc.) in the oil, the sub-micron particles can be filtered by holding the large technology which is particularly important for some precise and large key units.
The working state data display of the balanced charge oil filter is shown (man-machine interface design), which can display the flow rate and leakage current value any time.
Winsonda balanced charge oil filter can be equipped with vacuum system to quickly and effectively remove water and gas.
The equipment material of the balanced charge oil filter is made of stainless steel and carbon steel.
Weisda balanced charge oil filter has automatic shutdown alarm, no monitoring in the operation.
Weisda balanced charge oil filter is fully surrounded, overall skid mounted, mobile.
