Description

Technical Field

[0001] This utility model belongs to the field of diesel supply technology, and more specifically, it relates to a diesel supply system for a diesel generator set. Background Technology

[0002] As the core carrier of information infrastructure, the reliability of power supply to data centers affects business continuity. Currently, data centers generally use diesel generator sets as backup power. The diesel supply system usually includes fuel tanks, fuel pumps, fuel supply and return pipelines and control components. Its core function is to quickly and stably supply fuel to the diesel generator set when the mains power is interrupted, so as to ensure the continuous operation of the backup power.

[0003] Existing diesel generator sets mostly use a single-path design for diesel supply and return pipelines, and rarely have backup units. While this simplified design can meet the basic needs of general scenarios, it exposes significant defects in environments with high reliability requirements, such as data centers. The single-path pipeline system has the risk of single point of failure. When a leak, blockage, or mechanical damage occurs at any point in the supply and return pipeline, it may cause some or all diesel generator sets to stop running, which in turn leads to a power outage in the data center, resulting in business paralysis, data loss, and other consequences. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a diesel supply system for diesel generator sets. This system solves the technical problem that traditional diesel generator sets, which employ a single-path structure, have a single-point failure risk. When leakage or blockage occurs at any point in the supply or return oil pipeline, it can lead to partial or complete shutdown of the diesel generator set due to fuel shortage.

[0005] The purpose and effectiveness of this utility model's diesel supply system for a diesel generator set are achieved through the following specific technical means:

[0008] Two sets of first diesel fuel supply pipes are connected to the first annular diesel fuel supply main pipe, and two sets of first diesel fuel return pipes are connected to the first annular diesel fuel return main pipe. The two sets of first diesel fuel supply pipes and the two sets of first diesel fuel return pipes are respectively connected to the two sets of diesel generator sets. Four sets of first valves are provided on both the first annular diesel fuel supply main pipe and the first annular diesel fuel return main pipe. The four sets of first valves are located at both ends of the connection between the first annular diesel fuel supply main pipe and the two sets of first diesel fuel supply pipes, and the other four sets of first valves are located at both ends of the connection between the first annular diesel fuel return main pipe and the two sets of first diesel fuel return pipes.

[0009] According to a preferred embodiment, one side of the first annular diesel fuel supply pipe is connected to both ends of the second annular diesel fuel supply pipe, and one side of the first annular diesel fuel return pipe is connected to both ends of the second annular diesel fuel return pipe.

[0010] According to a preferred embodiment, four sets of second valves are provided on both the first annular diesel fuel supply main pipe and the first annular diesel fuel return main pipe, wherein the four sets of second valves are respectively located at both ends of the connection between the first annular diesel fuel supply main pipe and the second annular diesel fuel supply main pipe, and the other four sets of second valves are respectively located at both ends of the connection between the first annular diesel fuel return main pipe and the second annular diesel fuel return main pipe.

[0011] According to a preferred embodiment, one side of the second annular diesel fuel supply main pipe is connected to two sets of diesel generator standby units via two sets of second diesel fuel supply pipes, and the other side of the second annular diesel fuel return main pipe is provided with two sets of second diesel fuel return pipes, which are respectively connected to the two sets of diesel generator standby units.

[0012] According to a preferred embodiment, four sets of third valves are provided on both the second annular diesel fuel supply main pipe and the second annular diesel fuel return main pipe. The four sets of third valves are respectively located at both ends of the connection between the second annular diesel fuel supply main pipe and the two sets of second diesel fuel supply pipes, and the other four sets of third valves are respectively located at both ends of the connection between the second annular diesel fuel return main pipe and the two sets of second diesel fuel return pipes.

[0013] According to a preferred embodiment, both sets of diesel generator sets and both sets of diesel generator standby sets are equipped with day fuel tanks, and each day fuel tank is equipped with a magnetic float level measuring device and a flame arrestor breather valve.

[0014] The two sets of first diesel fuel supply pipes and the two sets of first diesel fuel return pipes are respectively connected to the day fuel tanks on the two sets of diesel generator sets, and the two sets of second diesel fuel supply pipes and the two sets of second diesel fuel return pipes are respectively connected to the day fuel tanks on the two sets of diesel generator standby sets.

[0015] According to a preferred embodiment, both sets of diesel storage tanks are equipped with detection tubes, and both sets of diesel storage tanks are equipped with steel cover plates on top, with magnetic float level gauges installed at the bottom of the steel cover plates.

[0016] According to a preferred embodiment, the top of each of the two sets of diesel storage tanks is also connected to an oil unloading pipe, the bottom of which is connected to the two sets of diesel storage tanks via two sets of oil unloading valves, and one end of the oil unloading pipe is connected to a rotary flow meter and a diesel filter.

[0018] According to a preferred embodiment, the first annular diesel fuel supply main pipe and the first annular diesel fuel return main pipe are respectively connected to the two sets of diesel storage tanks through two sets of anti-overflow unloading valves.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. By setting up a first ring-shaped diesel fuel supply main pipe and a first ring-shaped diesel fuel return main pipe, and installing a first valve at both ends of the connection between each set of diesel fuel supply pipes and return pipes, when a section of the pipeline leaks or gets blocked, the corresponding valve can be closed to control the fault range within a single pipeline, avoiding affecting the fuel supply of other diesel generator sets. This solves the problem of the entire set of fuel being cut off due to a single point of failure in traditional single-line pipelines, ensuring the continuity of diesel fuel supply.

[0021] 2. The first ring network and the second ring network are connected by a second valve, and the second ring network is connected to the diesel generator standby unit. Under normal operation, the two ring networks can work independently or in coordination. When a diesel generator set fails or its corresponding network has a problem, the second valve can be opened to switch to the other ring network and start the standby unit. The diesel fuel supply and return pipes of the second ring network supply fuel to the standby unit, achieving dual redundancy of "primary + standby". This ensures that the system can maintain power supply through the standby circuit when the primary pipeline or unit fails, avoiding the risk of data center shutdown due to diesel supply interruption.

[0025] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model. Example

[0026] As attached Figure 1 As shown:

[0027] This utility model provides a diesel supply system for a diesel generator set, including two sets of diesel storage tanks 11 buried underground and two sets of diesel generator sets 12 installed outdoors. A first annular diesel supply main pipe 13 and a first annular diesel return main pipe 14 are provided between the two sets of diesel storage tanks 11.

[0028] Two sets of first diesel fuel supply pipes 15 are connected to the first annular diesel fuel supply main pipe 13, and two sets of first diesel fuel return pipes 16 are connected to the first annular diesel fuel return main pipe 14. The two sets of first diesel fuel supply pipes 15 and the two sets of first diesel fuel return pipes 16 are respectively connected to two sets of diesel generator sets 12. Four sets of first valves 17 are provided on both the first annular diesel fuel supply main pipe 13 and the first annular diesel fuel return main pipe 14. The four sets of first valves 17 are located at both ends of the connection between the first annular diesel fuel supply main pipe 13 and the two sets of first diesel fuel supply pipes 15, and the other four sets of first valves 17 are located at both ends of the connection between the first annular diesel fuel return main pipe 14 and the two sets of first diesel fuel return pipes 16.

[0029] Specifically, by setting up a first annular diesel fuel supply main pipe 13 and a first annular diesel fuel return main pipe 14, and installing a first valve 17 at both ends of the connection between each diesel fuel supply pipe and return pipe, when a section of the pipeline leaks or gets blocked, the corresponding valve can be closed to control the fault range to a single pipeline, avoiding affecting the fuel supply of other diesel generator sets 12. This solves the problem of the entire set losing fuel due to a single point of failure in a traditional single pipeline, ensuring the continuity of diesel fuel supply.

[0030] The first annular diesel fuel supply main pipe 13 is connected to both ends of the second annular diesel fuel supply main pipe 18 on one side, and the first annular diesel fuel return main pipe 14 is connected to both ends of the second annular diesel fuel return main pipe 19 on one side.

[0031] Four sets of second valves 20 are provided on both the first annular diesel fuel supply main pipe 13 and the first annular diesel fuel return main pipe 14. The four sets of second valves 20 are located at the two ends of the connection between the first annular diesel fuel supply main pipe 13 and the second annular diesel fuel supply main pipe 18, and the other four sets of second valves 20 are located at the two ends of the connection between the first annular diesel fuel return main pipe 14 and the second annular diesel fuel return main pipe 19.

[0032] On one side of the second annular diesel fuel supply main pipe 18, two sets of diesel fuel supply pipes 21 are respectively connected to two sets of diesel generator standby groups 22. On one side of the second annular diesel fuel return main pipe 19, two sets of diesel fuel return pipes 23 are respectively connected to the two sets of diesel generator standby groups 22.

[0033] Specifically, the first annular diesel fuel supply main 13 and the first annular diesel fuel return main 14 are connected to the second annular diesel fuel supply main 18 and the second annular diesel fuel return main 19 respectively through the second valve 20. The second annular diesel fuel supply main 18 and the second annular diesel fuel return main 19 are connected to the diesel generator standby group 22. During normal operation, the first annular diesel fuel supply main 13, the first annular diesel fuel return main 14 and the second annular diesel fuel supply main 18 and the second annular diesel fuel return main 19 can work independently or in coordination. When a diesel generator group 12 fails or its corresponding pipeline network has a problem, the second valve 20 can be opened to switch to another annular pipeline network and start the diesel generator standby group 22. The second diesel fuel supply pipe 21 and the second diesel fuel return pipe 23 supply fuel to the diesel generator standby group 22, realizing the dual redundancy of "primary + standby". This allows the system to maintain power supply through the standby circuit when the primary pipeline or generator fails, avoiding the risk of data center shutdown due to diesel supply interruption.

[0034] Both the second annular diesel fuel supply main pipe 18 and the second annular diesel fuel return main pipe 19 are equipped with four sets of third valves 24. The four sets of third valves 24 are located at both ends of the connection between the second annular diesel fuel supply main pipe 18 and the two sets of second diesel fuel supply pipes 21, and the other four sets of third valves 24 are located at both ends of the connection between the second annular diesel fuel return main pipe 19 and the two sets of second diesel fuel return pipes 23.

[0035] Both sets of diesel generator sets 12 and both sets of diesel generator standby sets 22 are equipped with day fuel tanks 36. Each day fuel tank 36 is equipped with a magnetic float level measuring device 25 and a flame arrestor breather valve 26. The magnetic float level measuring device 25 can display the fuel level, and the flame arrestor breather valve 26 can maintain the stable air pressure in the fuel tank to prevent fuel evaporation or air intrusion from affecting the fuel supply.

[0036] Two sets of first diesel fuel supply pipes 15 and two sets of first diesel fuel return pipes 16 are respectively connected to the day fuel tanks 36 on the two sets of diesel generator sets 12, and two sets of second diesel fuel supply pipes 21 and two sets of second diesel fuel return pipes 23 are respectively connected to the day fuel tanks 36 on the two sets of diesel generator standby sets 22.

[0037] Both sets of diesel storage tanks 11 are equipped with detection tubes 27, and both sets of diesel storage tanks 11 are equipped with steel cover plates 28 on the top to prevent external impurities from entering. A magnetic float level gauge 29 is installed at the bottom of the steel cover plate 28 to monitor the oil level in the tank.

[0038] Both sets of diesel storage tanks 11 are also connected to the top of an oil unloading pipe 30. The bottom of the oil unloading pipe 30 is connected to the two sets of diesel storage tanks 11 through two sets of oil unloading valves 31. One end of the oil unloading pipe 30 is connected to a rotary flow meter 32 and a diesel filter 33 to ensure accurate measurement and filtration of impurities during the oil unloading process and to avoid clogging of the pipes.

[0039] Both sets of diesel storage tanks 11 are equipped with flame-arresting vent caps 34 on their tops. The first annular diesel supply main pipe 13 and the first annular diesel return main pipe 14 are connected to the two sets of diesel storage tanks 11 through two sets of anti-overflow unloading valves 35, which can prevent fuel spillage during unloading. Combined with the setting of flame-arresting vent caps 34, the fire hazard is reduced, and the stability and safety of the system operation are improved from multiple aspects such as fuel supply safety, impurity filtration, and liquid level monitoring.
