[0036] The utility model is described in detail below in conjunction with specific embodiments. The following embodiments will help those skilled in the art to further understand the utility model, but do not limit the utility model in any form. It should be pointed out that for those of ordinary skill in the art, several changes and improvements can be made without departing from the concept of the utility model. These all belong to the protection scope of the utility model.

[0037] like Figure 1 and Figure 2 As shown, according to the utility model, a lubricating oil filter element replacement device suitable for non-stop operation of an aero-derivative gas turbine generator set is provided, which is used to replace the lubricating oil filter element. By continuously filtering the lubricating oil of the gas turbine, the operating safety of the entire gas turbine is improved.

[0038] like Figure 1 As shown, the device includes a lubricating oil inlet 1, a lubricating oil outlet 2, a lubricating oil filter element regulating control valve 3, a first lubricating oil filter element 4, a second lubricating oil filter element 5, a filter element connecting valve 6, a lubricating oil inlet pressure indicating valve 7, a lubricating oil outlet pressure indicating valve 8, and a lubricating oil pressure indicator 9. The lubricating oil outlet pressure indicating valve 8, the lubricating oil pressure indicator 9, and the lubricating oil inlet pressure indicating valve 7 are sequentially connected and arranged between the lubricating oil inlet 1 and the lubricating oil outlet 2. Two lubricating oil filter element regulating control valves 3 are provided, which are respectively connected to the lubricating oil inlet 1 and the lubricating oil outlet 2. A lubricating oil filter pipeline is arranged in parallel between the two lubricating oil filter element regulating control valves 3, including a first lubricating oil filter element 4 and a second lubricating oil filter element 5, and also includes a filter element connecting valve 6 connecting the two lubricating oil filter pipelines.

[0039] The housing for placing the lubricating oil filter element is made of 304 or 316 stainless steel to prevent corrosion from the external environment; the lubricating oil filter element regulating control valve can have three openings to control the lubricating oil to pass through two different filter elements or two filter elements; the engine lubricating oil inlet connecting hose and the engine lubricating oil outlet connecting hose are made of high-pressure braided mesh rubber hose.

[0040] The external engine lubricating oil enters the entire device from the lubricating oil inlet 1, and enters the first lubricating oil filter 4, the second lubricating oil filter 5 or the two filters through the filter connecting valve 6 under the control of the lubricating oil filter element regulating control valve 3. The filtered lubricating oil returns to the entire engine system from the lubricating oil outlet 2.

[0041] The lubricating oil inlet pressure indicating valve 7, the lubricating oil outlet pressure indicating valve 8 and the lubricating oil pressure indicator 9 monitor the state of the lubricating oil flowing through the whole system. The lubricating oil pressure indicator 9 keeps the pressure difference below 0.7 bar.

[0042] When the planned maintenance period arrives or when the lubricating oil pressure indicator 9 shows that the pressure difference between the lubricating oil outlet and the lubricating oil inlet exceeds 0.7 bar, the lubricating oil filter element must be operated.

[0043] Move the lubricating oil filter regulating control valve 3 to bypass one lubricating oil path, so that the lubricating oil only passes through one of the first lubricating oil filter 4 and the second lubricating oil filter 5. Replace the lubricating oil filter of one path, and then move the lubricating oil filter regulating control valve 3 to the other path, and perform the same operation.

[0044] Compared with the general lubricating oil filter, by arranging two lubricating oil filters and two circuits, the number of shutdowns caused by replacing the lubricating oil filter is reduced, and the service life of the aeroderivative gas turbine generator set is greatly extended. Because two lubricating oil filters are arranged, redundancy is achieved, and the failure of one of the lubricating oil filters will not cause an unexpected reduction in the lubricating oil flow. At the same time, because the lubricating oil pressure indicator 9 is set to monitor the conditions of the two lubricating oil filter elements, the safety of the aeroderivative gas turbine generator set is improved.

[0045] In the description of the present application, it should be understood that the terms "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.
