Description

Technical Field

[0001] The utility model relates to the technical field of lubricating oil filtering, in particular to a lubricating oil filtering device and a lubricating system. Background Art

[0002] The fuel-driven compressor units used in long-distance natural gas pipelines are mainly composed of gas turbines, centrifugal compressors and auxiliary systems. The gas turbines and compressors are each equipped with an independent lubricating oil system with two lubricating oil tanks, which use industrial mineral oil to lubricate and cool their rotating bearings and gears. As an important part of the fuel-driven compressor unit, the lubricating oil system is closely related to the smooth operation of the unit.

[0003] The lubricating oil system pipeline is equipped with an oil supply pump and an oil return pump, and the oil return pipeline is equipped with a metal debris detection device. When the gears, bearings and other parts inside the engine and compressor collide or wear and produce metal debris, the metal debris will flow through the loop pipeline. When the metal debris detection device detects metal debris, it will trigger the alarm device and send an alarm message to the staff. A primary filter device is installed at the place where the return oil pipeline enters the lubricating oil tank to filter impurities in the return oil pipeline to prevent contamination of the oil in the lubricating oil tank. During actual operation, when serious defects occur in the bearings, gears and other parts inside the engine, resulting in failure, a large amount of metal debris flows through the loop pipeline. Although the metal debris detection device can send out an alarm message, it cannot make an accurate judgment on the failure mode because it cannot observe the specific situation of the metal debris, which affects emergency decision-making. In addition, the single-stage filter device on the return oil pipeline can only filter large particles of metal debris or impurities, and cannot effectively filter fine metal debris. When fine metal debris flows into the lubricating oil tank, it will cause oil pollution in the lubricating oil tank. If it flows into the engine through the oil inlet pipeline, it will aggravate the wear of the mechanical parts inside the engine and even cause the failure of key components of the unit.

[0049] The embodiment of the present invention provides a lubricating oil filtering device and a lubricating system, which can be a lubricating oil filtering device for a gas-driven compressor with a transparent window and a strong magnetic structure.

[0051] The filtering device is installed on the oil return pipeline of the lubricating oil station.

[0052] The metal housing 1 of the filtering device is provided with a circulation inlet 6 and a circulation outlet 7, which are connected to the oil return pipeline through a connecting flange 8.

[0053] The transparent window 2 of the filtering device is integrally made of tempered glass and a stainless steel outer ring, and is installed on the window installation openings on both sides of the metal housing 1 through a connecting thread 9, without reducing the strength of the metal housing of the filtering device and meeting the airtight pressure-bearing function during the operation of the unit.

[0054] A double-layer cylindrical filter element is installed inside the metal housing 1 of the filtering device. Among them, the outer filter element (strong magnetic filter element 3) is made of a strong magnetic material and is connected and fixed to the bottom of the metal housing 1 through a card slot. The inner filter element (non-magnetic filter element 5) is composed of a non-magnetic material and is connected to the metal housing 1 through a thread. The two filter elements are separated from each other, and a certain gap is reserved in the middle. The pore diameter of the inner filter element can be smaller than that of the outer filter element.

[0060] During the operation of the gas turbine, the oil flows into the filtering device through the circulation inlet 6 via the oil return pipeline, first passes through the outer strong magnetic filter element 3 for filtration and adsorption to remove metal impurities in the oil, and then passes through the inner non-magnetic filter element 5 to further filter non-metallic impurities in the oil port, and then flows out of the filtering device through the circulation outlet 7.

[0061] During the operation of the gas turbine, the color of the oil in the oil return pipeline can be observed through the transparent window 2 to preliminarily judge the quality of the oil.

[0062] When the metal detection device in the lubricating oil return pipeline continuously gives an alarm, the lifting rod 4 and the strong magnetic filter element 3 are lifted upward by rotating and lifting the lifting handle 11 at the top of the filtering device to expose the oil surface, and the filtering and adsorption conditions of the metal impurities on the surface of the magnetic filter element 3 are observed through the transparent window 2 to intuitively judge the overall health status of the unit.

[0063] When it is necessary to reinstall the strong magnetic filter element 3, press down the lifting handle 11, align it with the card slot, and then rotate the lifting handle 11 clockwise to fix the strong magnetic filter element 3.

When the outer strong magnetic filter element is lifted, the inner non-magnetic filter element still performs the oil filtering function to ensure the oil filtering effect of the oil return pipeline and prevent impurities in the oil return pipeline from flowing into the lubricating oil tank and polluting the oil.

[0067] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model and are not intended to limit them; although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that it is still possible to modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present utility model.
