In fact, there are regular filter labels, we can use the labels to verify their filters, and if it is a high efficiency filter, well-known brands such as Atlas filters, they have special anti-counterfeiting labels, you can call the. So how does the high efficiency filter work?
The implementation of the high efficiency filter is divided into three steps: determining the typical components of the dynamic oil film clearance and the goal of cleanliness; select the appropriate filter system; stick to the difference to replace the filter, with regular monitoring.
First, from the point of view of pollution control, and the dynamic oil film gap size is similar to the maximum size of the particle. Because of this size range of particles into the movement of the gap between the parts, will cause the parts surface wear, and to increase the gap between the parts, so that larger particles into the gap, causing further wear. This continues, wear and tear, and finally lead to failure of components. Experience has proved that the use of beta 3200 high precision filter pump and motor can be extended 4 ~ 10 times, can basically eliminate the pollution of hydraulic valve tight situation, and significantly extend the use of hydraulic oil cycle.
Second, strengthen the inspection and replacement of the filter element with the pressure difference, condition monitoring. High precision filter filter replacement pressure difference according to the system is different, need to strengthen the communication with the filter manufacturers in accordance with the situation. Condition monitoring not only contains the oil cleanliness, water content, viscosity, but also including the iron spectrum, spectrum, energy spectrum and other monitoring measures, but the key factors of cleanliness monitoring. It should be noted that the sampling methods and testing instruments have great influence on the cleanliness monitoring, and the sampling personnel should be trained by the relevant departments.
Third, the selection of the filter system needs to be considered from three aspects: the filter position, the installation form, the filter ratio, and the filter material. The general hydraulic lubrication system filtering device at the beginning of the design is in accordance with the corresponding design specification, this does not have to say, only in the pressure oil and return oil filtering system, filtering performance are different degree of the filter is affected by the flow and pressure fluctuation, the filtration efficiency is significantly reduced. External circulation filtering device can be used at high precision of filtration cycle, external circulation flow system (Lmin) recommended tank volume (L) from 5% to 20%, poor working environment and system of high cleanliness requirements, recommend large value. In addition, the outer circulation filtering device can pre filter the oil in the oil tank before working in the main system, so as to effectively protect the oil pump of the main system. At the same time, it can combine with the dehydration of oil, gas and heat exchanger, to realize the comprehensive control of oil temperature and pollution.
