Description

Technical Field

[0001] This utility model relates to the field of monitoring and filtration equipment technology, and in particular to a device for monitoring and filtration protection of water leakage from a compressor hydraulic oil heat exchanger. Background Technology

[0002] Diaphragm compressors are generally used to pressurize high-purity hydrogen to 20 MPa for filling tube bundle vehicles. The entire working process of a diaphragm compressor involves two compression stages: a piston draws hydraulic oil to drive diaphragms on both sides, simultaneously drawing hydrogen to increase pressure. During this process, the hydraulic oil temperature becomes extremely high, necessitating a circulating water heat exchanger. This heat exchanger is typically located inside the hydraulic oil tank, with copper tubes on its inner side separating the cooling water from the hydraulic oil for heat exchange. Under normal circumstances, the hydraulic oil and cooling water are completely separate. However, if an abnormality occurs, such as a copper tube rupture, cooling water can enter the hydraulic oil. If the diaphragm compressor is started without proper precautions, water will enter the entire oil circuit and lubrication system, potentially damaging bearings, the lubrication system, and causing extremely serious consequences. Simultaneously, the broken copper tube will also form fine metal particles that enter the hydraulic oil, damaging the entire hydraulic system. Therefore, a device that can easily monitor and filter impurities is needed. Utility Model Content

Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0023] In this document, the directional terms such as front, back, top, and bottom are defined based on the location of the components in the accompanying drawings and their relationship to each other, solely for the purpose of clarity and convenience in expressing the technical solution. It should be understood that the use of these directional terms should not limit the scope of protection claimed in this application.

[0024] Where there is no conflict, the above embodiments and features described herein can be combined with each other.

[0025] Please refer to Figure 1 The present invention provides a compressor hydraulic oil heat exchanger rupture and leakage monitoring and filtration protection device, which includes a hydraulic oil tank 1, a heat exchanger 2, a buffer tank 3, and a filter 10.

[0026] In this embodiment, hydraulic oil tank 1 provides hydraulic oil to the compressor in actual working conditions and is located in the entire hydraulic oil circulation system. Heat exchanger 2 is located inside hydraulic oil tank 1 to cool and dissipate heat for the entire hydraulic oil circulation system.

[0027] Furthermore, the oil inlet of the buffer tank 3 is connected to the bottom of the hydraulic oil tank 1 through a pipe, and a first switch valve 12 is provided on the pipe between the buffer tank 3 and the hydraulic oil tank 1, so that the hydraulic oil in the hydraulic oil tank 1 can enter the buffer tank 3 by closing the first switch valve 12 when needed.

[0028] Meanwhile, several buffer plates 4 are arranged alternately inside the buffer tank 3, and each buffer plate 4 is fixedly connected to the inside of the buffer tank 3. The main purpose of having several buffer plates 4 inside the buffer tank 3 is to buffer the hydraulic oil entering the buffer tank 3 when the hydraulic oil from the hydraulic oil tank 1 enters the buffer tank 3, so as to avoid impact.

[0029] The oil outlet of the buffer tank 3 is connected to a four-way connector 18. The oil inlet of the four-way connector 18 is connected to the oil outlet of the buffer tank 3. The first oil outlet of the four-way connector 18 is connected to the bottom of the hydraulic oil tank 1. The second oil outlet is connected to a monitoring tank 6. The third oil outlet is connected to the sampling tank 8 and the filter 10 respectively.

[0030] Specifically, the first oil outlet of the four-way connector 18 is connected to the bottom of the hydraulic oil tank 1 through a pipe, and a first oil pump 5 and a fifth switch valve 16 are sequentially provided on the pipe along the hydraulic oil flow direction, so that the hydraulic oil in the buffer tank 3 can be discharged back into the hydraulic oil tank 1 through the first oil pump 5 when needed.

[0031] The second oil outlet of the four-way connector 18 is connected to the monitoring tank 6 through a pipeline, and a second switch valve 13 is provided on the pipeline. At the same time, an oil-water mixing sensor 7 is provided in the monitoring tank 6. Thus, when it is necessary to detect whether water has mixed in the hydraulic oil, the hydraulic oil can be allowed to enter the monitoring tank 6 through the second switch valve 13, and then detected by the oil-water mixing sensor 7.

[0032] The third oil outlet of the four-way connector 18 is connected to a three-way connector 19. The oil inlet of the three-way connector 19 is connected to the third oil outlet of the four-way connector 18. The first oil outlet of the three-way connector 19 is connected to the sampling tank 8 through a pipeline, and a third switch valve 14 is provided on the pipeline. In this way, when it is necessary to test whether the hydraulic oil has too many impurities, the hydraulic oil can be introduced into the sampling tank 8 through the third switch valve 14, and then the hydraulic oil in the sampling tank 8 can be tested by external equipment.

[0033] The second oil outlet of the three-way connector 19 is connected to the filter 10 through a pipe, and a fourth switch valve 15 and a second oil pump 9 are sequentially arranged on the pipe along the hydraulic oil flow direction. In this way, when there are too many impurities in the detected hydraulic oil, the hydraulic oil can be filtered into the filter 10 through the fourth switch valve 15.

[0034] The oil outlet of the filter 10 is connected to the bottom of the hydraulic oil tank 1 through a pipe, and a pressure regulating valve 11 and a sixth switching valve 17 are sequentially provided on the pipe along the direction of hydraulic oil flow, so that the hydraulic oil after impurities are removed can be reintroduced into the hydraulic oil tank 1.

[0035] The compressor hydraulic oil heat exchanger rupture and leakage monitoring and filtration protection device in this embodiment operates as follows: When it is necessary to detect whether hydraulic oil has entered water, the hydraulic oil can be introduced into the monitoring tank 6 through the second switch valve 13, and then detected by the oil-water mixing sensor 7; when it is necessary to detect whether there are too many impurities in the hydraulic oil, the hydraulic oil can be introduced into the sampling tank 8 through the third switch valve 14, and then the hydraulic oil in the sampling tank 8 can be detected by external detection equipment; when the hydraulic oil is normal, the normal hydraulic oil can be introduced back into the hydraulic oil tank 1 through the fifth switch valve 16; when there are too many impurities in the hydraulic oil, the hydraulic oil can be introduced into the filter 10 through the fourth switch valve 15 for filtration, and then the filtered hydraulic oil can be introduced back into the hydraulic oil tank 1 through the sixth switch valve 17.

[0036] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
