Description

Technical Field

[0001] This utility model relates to the field of booster pump technology, and in particular to a booster pump leakage detection structure. Background Technology

[0002] A booster pump is a mechanical device used to increase pressure. Among them, a gas booster pump is a key industrial device that converts lower-pressure input gas into higher-pressure output gas. Its function is to provide a stable and reliable high-pressure gas source for various processes or experimental devices.

[0003] Gas booster pumps often use a piston structure, which compresses air by driving the piston. Under long-term operation, the sealing structure such as the sealing ring on the piston will wear, which will reduce the boosting effect, and cause safety hazards such as gas pollution and gas leakage. When the pressure in the pipeline is abnormal, it is impossible to accurately determine whether the pressure abnormality is caused by the reduced piston sealing, and it is also impossible to detect the piston sealing in real time.

[0019] The following describes the embodiments in conjunction with the appendix. Figure 1-3 This utility model will be described in further detail.

[0020] A booster pump leakage detection structure includes a booster pump and a detection channel 4.

[0021] The booster pump includes a first cylinder 1, a second cylinder 2, a connecting channel 3, a detection channel 4, an intake pipe 5, and an exhaust pipe 6. Specifically, in this embodiment, the booster pump is a two-stage booster pump.

[0022] The first cylinder body 1 includes a first booster front cover 11, a first booster rear cover 12, a first booster cylinder 13, and a first booster piston 14. The first booster front cover 11 and the first booster rear cover 12 enclose the first booster cylinder 13 to form the first cylinder body 1. The first booster piston 14 is installed inside the first cylinder body 1. A first booster chamber 15 is formed between the first booster piston 14 and the first booster rear cover 11. A first collection chamber 16 is formed between the first booster piston 14 and the first booster front cover 12. The first booster rear cover 12 is provided with a first one-way air inlet 121 and a second one-way air outlet 222. The first one-way air inlet 121 and the second one-way air outlet 222 are connected to the first booster chamber 15.

[0023] The second cylinder body 2 includes a second booster front cover 21, a second booster rear cover 22, a second booster cylinder 23, and a second booster piston 24. The second booster front cover 21 and the second booster rear cover 22 enclose the second booster cylinder 23 to form the second cylinder body 2. The second booster piston 24 is installed inside the second cylinder body 2. A second booster chamber 25 is formed between the second booster piston 24 and the second booster rear cover 22. A second collection chamber 26 is formed between the second booster piston 24 and the second booster front cover 21. The second booster rear cover 22 is provided with a second one-way air inlet 221 and a second one-way air outlet 222. The second one-way air inlet 221 and the second one-way air outlet 222 are connected to the second booster chamber 25.

[0024] The detection channel 4 includes a first pipe 41, a second pipe 42, and a detection port 43. The second pipe 42 connects the first pipe 41 and the detection port 43, and the detection port 43 is used to connect to external detection equipment.

[0025] The intake pipe 5 is connected to the first one-way intake port 121 of the first cylinder 1, and the exhaust pipe 6 is connected to the second one-way intake port 221 of the second cylinder 2. The connecting channel 3 is located outside the first cylinder 1 and the second cylinder 2. The connecting channel 3 connects the first one-way exhaust port 122 of the first cylinder 1 and the second one-way intake port 221 of the second cylinder 2, so that the first booster chamber 15 and the second booster chamber 25 are connected. The first pipe 41 of the detection channel 4 is simultaneously connected to the first collection chamber 16 of the first cylinder 1 and the second collection chamber 26 of the second cylinder 2.

[0026] The working process of a booster pump leakage detection mechanism: like Figure 3As shown, gas enters the first pressurization chamber 15 from the intake pipe 5 for pressurization, then enters the second pressurization chamber 25 for secondary pressurization through the connecting channel 3, and is output to the outside from the outlet pipe 6. When the sealing performance of the first pressurization piston 14 or the second pressurization piston 24 decreases, causing gas leakage, some gas enters the first collection chamber 16 and the second collection chamber 26. The leaked gas in the first collection chamber 16 and the second collection chamber 26 flows through the first pipe 41 of the detection channel 4 to the detection port 43. The leaked gas is detected by the external equipment connected to the detection port 43, thereby determining the piston sealing performance, facilitating timely maintenance, and reducing safety hazards.

[0027] The advantage of this invention is that the gap between the booster piston and the cylinder is used as a collection chamber, and the detection channel 4 is connected to the collection chamber. By detecting whether there is leaking gas in the collection chamber, the piston sealing performance can be determined, which facilitates timely maintenance and reduces safety hazards.

[0028] The above embodiments only illustrate one implementation of the present utility model, and should not be construed as limiting the scope of the utility model patent.
