It should be noted that: the terms such as "upper", "lower", "left", "right", "inner" and "outer" of the present invention are described with reference to the drawings, and are not intended to be limiting terms.

Referring to fig. 1 to 3, the high-stability oil filter shown in this embodiment is integrated by multiple oil paths, specifically, the high-stability oil filter includes an oil inlet path 1, an oil outlet path 2, a first oil path 3, a second oil path 4, and a third oil path 5, wherein the oil inlet path 1 is provided with an oil inlet valve 11, an oil suction filter 12, and an oil pump 13, the oil outlet path 2 is provided with an oil outlet valve 21, and the first oil path 3, the second oil path 4, and the third oil path 5 are respectively connected to the oil inlet path 1 and the oil outlet path 2. The oil inlet valve 11 is opened, the oil liquid flows into the oil absorption filter 12 under the action of the oil pump 13, and then large particles of insoluble impurities are filtered.

In the present embodiment, the first oil path 3 is used for removing insoluble impurities and moisture in the oil, and specifically, the coalescing and separating assembly is disposed on the first oil path 3 and includes a pre-filter 31 and a coalescing and separating device 32 disposed after the oil pump 13 along the oil flow direction. An ion exchange filter assembly is provided on the second oil passage 4, which includes an ion exchange filter 41 and a collection filter 42 provided after the oil pump 13 in the oil flow direction for removing varnish and colloidal matter in the oil. The balance charge filter assembly is disposed on the third oil passage 5, and includes a balance charge generator 51 and a collecting filter 42 disposed after the oil pump 13 in the oil flow direction for removing small particle insoluble impurities from the oil.

In order to avoid the need to frequently clean the oil suction filter 12, the combined oil filter system is provided with a first oil suction filter 121, a second oil suction filter 122, and a first oil pump 131 and a second oil pump 132 respectively arranged behind the first oil suction filter 121 and the second oil suction filter 122 along the oil flow direction in the present embodiment. The first oil passage 3 and the third oil passage 5 are provided after the first oil pump 131 in the oil flow direction; the second oil passage 4 is provided after the second oil pump 132 in the oil flow direction. By additionally arranging the second oil suction filter 122 and the second oil pump 132 to be in butt joint with the second oil path 4, frequent cleaning of the first oil suction filter 121 can be avoided, and the efficiency of oil filtering is ensured.

Shear stresses in the lubrication system can cause the oil to auto-degrade, which is the root cause of the sludge/varnish contamination. When these stresses are present, soft contamination can result, leading to control failure. For turbines, the low flow areas present in the lubrication system are particularly susceptible to degradation of oil quality. During turbine operation, these oil degradation by-products are highly soluble and not easily removed by the balanced charge technique due to the high oil temperature, and therefore soluble contaminants are removed by providing ion exchange filter 41. The ion exchange filter 41 performs functional group replacement of acidic oxides formed in the fluid by releasing ions, thereby rapidly removing a soluble paint film and reducing the MPC value. The fluid after being adsorbed and filtered by the ion exchange filter 41 is finally filtered by the collection filter 42, and oil with excellent oil quality can be obtained. In the present embodiment, two ion exchange filters 41 are included, and the ion exchange filters 41 are preferably arranged in series, but may be arranged in parallel in another embodiment.

The inventors have found that, after the oil filter has been used for a certain period of time, since a large amount of impurities are accumulated in the filters (the pre-filter 31, the ion exchange filter 41, the balance charge generator 51, and the collecting filter 42), when new oil is pumped into the oil filter, the impact thereof causes the impurities in the filters to fall into the oil. Therefore, this application has set up the frequency conversion subassembly in all oil feed pumps department and has controlled it to the input of regulation fluid, in order to avoid too big impact to produce above-mentioned condition.

In the present embodiment, the coalescing separator 32 includes a housing 321, a coalescing filter element 322 and a separating filter element 323 provided in the housing 321, a water storage chamber 324 communicating with the housing 321, and a first oil outlet 325 communicating with the oil outlet passage 2, which are of conventional structure and will not be described in detail. The oil liquid enters the first oil suction filter 121 under the action of the first oil pump 131, after large-particle insoluble impurities are removed, the oil liquid enters the pre-filter 31 to remove the insoluble impurities with common sizes, and then enters the coalescence separator 32, most of moisture in the oil liquid is removed by utilizing the coalescence separation principle, and the moisture is stored in the water storage chamber 324 and is discharged from the water discharge pipeline 326; the oil flows from the first oil outlet 325 to the oil outlet valve 21.

In the present embodiment, the coalescer separator 32 further includes a second oil outlet 327, and the second oil outlet 327 is connected to the suction filter 12 through a drain valve 328 and a pipe. This design may facilitate filter replacement for coalescer separator 32 by opening drain valve 328 and pumping out residual oil in coalescer separator 32 through second oil outlet 327 when filter replacement is desired.

In the present embodiment, the balanced charge generator 51 includes an inlet 511, an outlet 512, and two branch channels 513 connecting the inlet 511 and the outlet 512, and the inner wall surfaces of the two branch channels 513 are loaded with positive and negative high voltage electricity, respectively. When oil enters the balanced charge generator 51, the fluid carrying small particles is divided into two branches, high-voltage electrodes arranged on the branches load and charge the small particles respectively, positive charges are loaded on one branch runner 513, negative charges are loaded on the other branch runner 513, then the particles loaded with opposite charges are mixed and accumulated again at the outlet part 512, the positive charges and the negative charges are mutually attracted and accumulated together to form large-size particles, the particles with increased sizes are easily captured by a traditional precise mechanical filter, and therefore the small particles which are not easy to filter are more easily filtered and removed. Therefore, in the present embodiment, a collection filter 42 is provided in the third oil passage 5 for trapping the collected particulate matter.

In order to avoid the occurrence of backflow, the check valve 100 is arranged in the oil outlet valve 21, the first oil path 3 and the second oil path 4, so that the normal operation of the oil filter is guaranteed, and the safety of the equipment is improved.

In this embodiment, the combined oil filtering system further includes an oil return path 6, and the oil return path 6 communicates the oil outlet path 2 and the oil inlet path 1, so that the oil in the oil outlet path 2 flows into the oil inlet path 1 for filtering again. Preferably, a detector 61 is arranged on the oil outlet path 2 and/or the oil return path 6 to detect the content of impurities in the oil, and determine whether the oil needs to be re-filtered according to the detection result.

In the present embodiment, the detector 61 is a particle counter, however, the bubbles in the oil may affect the particle counter 61: the laser in the particle counter 61 counts the bubbles in the oil as impurities, and thus has detection errors. In another embodiment, not shown, a high-pressure pump may be provided on the return oil path to minimize the effect of air bubbles.

The combined oil filtering system of the embodiment can control the whole oil purifying process through an electric controller (not shown).

The present embodiment combines the charge balancing technology, the coalescence-separation technology and the exchange resin adsorption technology, and has submicron-level purification function, fast speed of decontamination and water removal, and high precision (capable of removing 0.02 μm of contaminants). The van der Waals effect and the coulomb effect between the active sites of the adsorbent and the charged ions, particles or polar molecules are utilized to selectively capture the ions, particles or molecules harmful to the oil liquid, so that the aim of purifying and regenerating the oil liquid is fulfilled. The resin adsorption regeneration can not only remove the paint film degradation product dissolved in the oil, but also quickly recover the physical and chemical indexes of the oil, thereby greatly prolonging the service life of the oil. By utilizing the principle of coalescence and separation, the water in the oil can be quickly removed.

In summary, the following steps: the high stability oil filter of this application can prevent in the filter that impurity from falling into fluid, and then all detach impurity, paint film, colloid thing and water in the fluid steadily, need not to set up a plurality of oil filter device, has reduced the oil strain cost and has increased oil strain efficiency.
