　　Waste oil filtration and purification equipment has become a very important energy-saving product in the current production and life. Because it can not only save oil cost, but also reduce equipment wear and failure probability caused by oil pollution. Therefore, the oil filter is widely used in electric power, oil and gas, mining, machinery manufacturing, steel, metallurgy, chemical industry, railway, paper making, pharmaceutical, shipping, shipping and various large-scale production enterprises, which indeed brings many good effects to users.

　　Because of the need of the market, there are many kinds of oil filters in the market, but the quality is also uneven. No matter the price, function and purification effect of the oil filter are all within the user's selection reference range, but because many of the market's oil filter manufacturers' propaganda are too pompous, it's easy for customers to lose the right direction of shopping, so they can't effectively consider the principle of high sex price ratio.

　　Now, Chongqing Zhongjing filter equipment, as an oil filter R & D manufacturer, reminds all users that, in fact, on the way to purchase oil filters, it is not easy to be fooled by others by carefully referring to the following problems, so as to more easily buy practical oil filter products:

　　1. Particle properties of new oil or waste oil to be treated (belong to common mechanical impurities? Is there metal powder? Is there oil sludge or dust impurities?):

　　2. What is the impurity content (refer to the impurity properties in * bar, and then see the approximate percentage of them in the oil):

　　3. Water content (understand the percentage of water content in the oil, the normal water content in the national standard of lubricating oil is trace, which is not more than 0.03% after conversion; the value of insulating oil is lower, generally several ppm values, which depends on your production needs):

　　4. Whether it is emulsified (whether the color is turbid and white, in fact, many oil products can be emulsified to milk like color and can also be filtered and purified to transparent state through dehydration oil filter):

　　5. What is the viscosity of the oil (or the label of the oil, hydraulic oil? Gear oil? Lubricating oil? The kinematic viscosity of the oil at room temperature is not large? Does this reference need to use a special oil filter with high viscosity)

　　6. Whether there is corrosivity (whether there is corrosion in the machinery or parts of oil application, whether the acid value in the oil exceeds the standard, if the acid value exceeds the standard, how much is the acid value, and what value you want to achieve after treatment, if there is reference to this value, a multifunctional oil filter with acid removal function is generally required):

　　7. Required hourly treatment capacity (know the total oil treatment quantity of users, and the oil treatment capacity requirements of each day or hour after conversion):

　　8. The choice of control system is to see whether you need ordinary oil filter or full-automatic oil filter: ordinary button or PLC (whether full-automatic control is required on the operating system, but in fact, if only PLC without touch screen control system, it is better not to need simple PLC control. The conventional operation of Tongrui oil filter is also very simple):

　　9. Whether imported configuration is required for parts configuration of oil filter equipment, such as main components such as oil pump or vacuum pump. But this is also part of the reason why prices are so heavy.

　　Look at the reference problems listed above, and then discuss them with the oil filter equipment manufacturers. Basically, you can fix the model and configuration of the oil filter. Then refer to the price, the actual equipment configuration and the comprehensive comparison of after-sales provided by the manufacturer, through the document form, it is OK!
