High-precision filter technology and its application in the field of modern manufacturing industry -

With modern manufacturing technology high-speed, high pressure, high control accuracy, high automation and high reliability of the development trend of mechanical power transmission equipment, some of more common use of axial piston pumps, proportional valves, servo valves, static pressure hydraulic bearing. The normal operation of such systems is highly demanding on the oil cleanliness, 75% ~ 85% of system failures due to particulate contaminants in the system. Particulate pollutants on the surface of the cutting device movement, adhesion, erosion caused by frequent hysteretic increase the proportion of servo systems, responding slowly, out of control and damage the pump and the bearing and even the occurrence of catastrophic accidents. Address these issues, previously commonly used by regular replacement of components, monitor system status at any time, or even increase the movement to reduce the surface of the dynamic gap accidents.

High-precision filter technology for machinery and equipment, blood?? Oils (including hydraulic oil, lubricating oil, cutting fluid, etc.), running on the system with high reliability requirements, using the concept of proactive and preventive maintenance strategy, a comprehensive equipment and components to understand the dynamic space operating conditions, a reasonable selection of filters, filter filtration precision and filter size, high efficiency particulate filter gap size, block wear the chain reaction, in conjunction with regular monitoring to ensure the oil and the system cleanliness, and thus to reduce wear, avoid repairs, extend the service life of components and equipment, improve the overall economic efficiency.

How to use high-precision filter technology

High-precision filter technology is the high-speed rolling with the metallurgical technology, modern hydraulic technology, aviation and space technology came into being. In the manufacturing industry, due to pollution control and equipment preventive maintenance initiative has not been widely promoted the idea of high-precision filtering technology has not been widely used. Some developed countries import equipment selection filters, filtering device when the filter element precision inadequate attention, resulting in operational shortly after the oil cleanliness is exceeded, equipment run accident rate remains high. Beijing Ou Luopu filter technology development companies in the manufacturing process and the actual use for proactive maintenance, through the implementation of high-precision filters to improve overall efficiency of equipment. The implementation of high-precision filter

three steps: identification of the typical components of the dynamic oil film clearance and target cleanliness; select the appropriate filtration system; adhere to replace the filter by pressure differential, with regular monitoring.

First, from the perspective of pollution control, and dynamic oil film clearance is similar to the particle size most harmful. Because the size range of particles into the campaign with clearance once inside, will give rise to the surface of wear parts, spare parts and to increase the gap, so the larger particles into space, causing further wear and tear. Things are going, wear growing, leading to component failure. Experience has shown that use 3> 200 high-precision filters, pumps and motors can extend the life of 4 to 10 times, can basically eliminate the pollution of the hydraulic valve clamping conditions, and significantly extend the life cycle of the hydraulic oil.

Second, the choice of filtration systems need to install the filter location and form of filtration, filtering materials of three considerations. General hydraulic lubrication system filter design at the beginning that the appropriate standard in accordance with the design, no need to repeat here, but in the pressure oil and return oil filtration system, filters, filter performance under varying degrees of flow and pressure fluctuations, the filtration efficiency decreased significantly. At this point you can use high-precision external loop filter for external loop filter, external circulation flow (L / min) recommended to take the tank volume (L) 5% ~ 20%, poor working conditions, the system requires high cleanliness, recommended to take a large value.

In addition, the external loop filter can also work in the main system within the oil tank before the pre-filter, can effectively protect the main system pump. At the same time with the oil of dehydration, in addition to gas and heat exchange device combination can be achieved on the oil's temperature control and integrated pollution control.

Filter selection than the main filter elements to consider whether the particle size of the dynamic oil film clearance fully efficient filter. High-precision filters generally use x> 200 of filtration products. Figure 1 shows a vehicle hydraulic system in the three-month field test in the curve of oil pollution. System from the nominal accuracy of 25 m filter filter replaced 3> 200 high-precision filter, running 20min, oil in reducing the number of particles greater than 5 m 100 times. After 300 hours after the operation than 5 m particles reduced to the minimum number of 2500, metal wear debris concentration close to 0. However, when the return for the previous precision of 25 m nominal filter filters after 100 hours, the oil in the increase in the number of particles larger than 5 m, 300 times, component wear has increased significantly.
