Oil filter selection and precautions

When it comes to oil filter machines, we may feel unfamiliar. The working principle of oil filter machines may not be the focus of our attention. For enterprises, how to choose oil filter machines and brands is very important. Today, the editor will tell you how to buy oil filter machines and precautions.

Generally speaking, there are many types of oil filter products on the market, and the shapes, functions, application methods, and purchase costs of oil filter equipment are completely different. Therefore, if new and old users intend to buy oil filter machines, please learn more about them so that you can buy more suitable products.

Precautions for selecting oil filter machines

Buy products with better quality. Before buying, you must first look at the quality and some parameters of the product and choose products with qualified quality.

Buy products with high cost performance.

1. The internal structure of the oil filter and its oil filtering effect are different. The first-stage oil filter has a simple structure, mainly a coarse filter element, and most of them can only be used for initial filtration.

2. Two-stage filter oil purifier. This oil filter has a set of coarse filters and a set of fine filters. The fine filter uses a hollow fiber filter element, which filters the oil more cleanly and meets the filtration standards. Multi-filter oil purifiers are medium-to-high-priced products.

3. Multi-stage filter oil purifier. It has multiple sets of filter elements for filtering, layer by layer, and the filtering effect is better than the double-stage effect. Generally speaking, the oil pollution is serious and the polluted oil meets the application standards.

Consideration factors

1. Filter elements: The temperature and viscosity of the material under filtering conditions, physical and chemical properties, unit time processing volume, humidity of the filter cake, solid content in the filtrate, and degree of cleaning of the filter cake are all factors we should consider when choosing a filter oil machine.

2.Oil filter machine filters the amount of filtration per hour 

3. Filter pump method: There are two types of filter pumps for oil filter machines: vertical and horizontal. The advantage of the vertical pump is that the gap is large, which is more suitable for the filtration of chemical plating solutions, but the equipment method is a little messier than the horizontal pump. Horizontal pumps have mechanical pumps and magnetic pumps. The former is more suitable for use when there are more solid particles, and the latter has no shaft seal and is not easy to leak.

4. Oil filter filter materials: Oil filter filter media include wire wound filters, non-woven filters, paper filters, laminated filter media, microporous tube filters, and mixed filters. Laminated filter media and microporous tube filter elements have good filtering accuracy, but the former is troublesome to operate and the latter is easy to clog. 

Wire wound filters are used more frequently, but they are difficult to clean and are used less frequently. Non-woven filter bags are easy to clean and use, and are used more frequently, but the source of the product has a greater impact on the filtering accuracy. 

In short, each has its advantages and disadvantages and should be selected according to the situation. There are also activated carbon filters, which can be treated with mild activated carbon when working.

Purchase knowledge

1. Confirm the type of oil to be treated (the oil filter on the market now mainly targets transformer oil insulating oil, common lubricating oil, steam turbine oil, and light fuel oil);

2. Are there any requirements for the amount of oil to be filtered and purified and the processing time?

3. How to use the oil filter, such as online equipment, mobile oil filter, maintenance and standby, etc.;

4. The main pollutants in the oil to be treated (is it simply filtering impurities, or does it need to deal with water impurities);

5. Whether the lubricating oil to be treated has special functions such as corrosiveness, whether it needs acid value neutralization treatment, whether the oil is severely oxidized, whether the color of the oil needs to be treated, etc.

How to choose an oil filter and key points for purchase

Understand the oil filter. Before choosing an oil filter, we should understand some basic knowledge about oil filters. Equipment practice quality.

When purchasing, we should look at the actual quality of the equipment, see if there is damage, collision, etc., and the manufacturer's promise. We should choose a manufacturer with good promises so that we can have a good product. Comparison of consumable prices.

When choosing, we should look at the price of consumables, compare more with others, and choose the right one. Don't believe in TV ads. Don't blindly believe in TV ads, go and see for yourself. When purchasing, it is also important to understand the manufacturer's after-sales service.

When purchasing an oil filter, we should consider many aspects, and should combine our own application, what it is used for, and our own capital investment. I hope the above information can play a little guiding role in our purchase of oil filters.
