Description

Technical Field

[0001] This utility model relates to a magnetic levitation blower test bench, specifically an expandable integrated test bench that allows multiple blowers to be tested sequentially multiple times. Background Technology

[0002] Magnetic levitation blowers are widely used in wastewater treatment and thermal power plants. Performance and noise levels are key parameters of concern to users. Substandard blower performance can lead to unsatisfactory process conditions or excessive performance, resulting in energy waste. Therefore, testing the performance and noise levels of magnetic levitation blowers is crucial. Magnetic levitation blowers typically employ a skid-mounted structure, with the blower unit housed within a skid-mounted enclosure, resulting in complex piping connections. Furthermore, the magnetic bearing controller undergoes varying degrees of adjustment during testing, causing the performance testing of a single blower to exceed the expected duration. When multiple blowers need to be tested in a short period, frequent disassembly and reassembly are unavoidable. Therefore, it is necessary to design a comprehensive testing platform that allows multiple blowers to undergo sequential, repeated performance tests. Utility Model Content

[0003] To address the aforementioned problems, the main objective of this utility model is to provide an expandable integrated test bench that allows for convenient and sequential performance testing of multiple blowers.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows:

[0005] A magnetic levitation blower integrated test platform includes a main test pipeline, a test pipeline for the first blower unit's outlet branch and a first butterfly valve, a test pipeline for the second blower unit's outlet branch and a second butterfly valve, a test pipeline for the third blower head's outlet branch and a third butterfly valve, a test pipeline for the fourth blower head's outlet branch and a fourth butterfly valve, a silencer, and a flow regulating valve.

[0006] Furthermore, the main test pipeline is divided into at least five sections by the air outlet pipelines of each blower, including reserved expansion interfaces and flow regulating valves.

[0007] Furthermore, one end of the test pipe for the first blower unit's outlet branch and the first butterfly valve are connected to the outlet of the blower unit, and the other end is connected to the first section interface of the main test pipe. One end of the test pipe for the second blower unit's outlet branch and the second butterfly valve are connected to the outlet of another blower unit, and the other end is connected to the second section interface of the main test pipe. In addition to the butterfly valve, the test pipes for the first and second blower units' outlet branch are also equipped with a wafer-type check valve. The third blower head outlet... One end of the air branch test pipeline and the third butterfly valve are connected to the air outlet of the blower head, and the other end is connected to the third section interface of the main test pipeline. One end of the fourth blower head air branch test pipeline and the fourth butterfly valve are connected to the air outlet of another blower head, and the other end is connected to the fourth section interface of the main test pipeline. The connection between the blower unit air branch test pipeline and the blower unit is equipped with a corrugated pipe, and each blower air outlet pipeline is connected to each section of the main air outlet pipeline through a flange interface structure to form a complete pipeline.

[0008] Furthermore, the test pipes of the first blower unit's outlet branch and the first butterfly valve, the test pipes of the second blower unit's outlet branch and the second butterfly valve, the test pipes of the third blower head's outlet branch and the third butterfly valve, and the test pipes of the fourth blower head's outlet branch and the fourth butterfly valve are all connected to the main test pipe, and each blower outlet branch test pipe is equipped with a temperature sensor and a pressure sensor.

[0009] Furthermore, the main test pipeline is equipped with a flow sensor, and additional sensor mounting holes are reserved.

[0010] Furthermore, one end of the muffler is connected to the main test pipe, and the other end is connected to the exhaust pipe. The air inlet of the blower head under test is connected to the air intake fixture, which is equipped with an air intake differential pressure sensor and a temperature sensor.

[0011] Furthermore, the expansion interface reserved in the main test pipeline is sealed by a flange structure.

[0012] The positive and progressive effects of this utility model are as follows: by designing multiple blower outlet pipe branches on the main pipeline of the experimental platform, the experimental platform can be connected to at least four blower devices at the same time, avoiding frequent disassembly and assembly of test pipes and other test fixtures when multiple devices are subjected to long-term, phased performance tests in a short period of time; while the experimental platform has multiple interfaces, it also reserves open expansion interfaces, which can not only conduct the above-mentioned tests on magnetic levitation blowers of different specifications, but also ensure that the experimental platform has sufficient expansion capabilities.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0020] like Figure 1-3 The image shows a magnetic levitation blower integrated test bench, including a main test pipe 1, a test pipe for the first blower unit's air outlet branch and a first butterfly valve 2, a test pipe for the second blower unit's air outlet branch and a second butterfly valve 3, a test pipe for the third blower head's air outlet branch and a third butterfly valve 4, a test pipe for the fourth blower head's air outlet branch and a fourth butterfly valve 5, a silencer 6, and a flow regulating valve 8.

[0021] like Figure 1-3As shown, the main test pipeline 1 is divided into at least five sections by the air outlet pipelines of each blower, including a reserved expansion interface 7 and a flow regulating valve 8; the first blower unit air outlet branch test pipeline and the first butterfly valve 2 are connected at one end to the air outlet of the blower unit and at the other end to the first section interface of the main test pipeline 1.

[0022] The test pipeline of the second blower unit's outlet branch and the second butterfly valve 3 are connected at one end to the outlet of another blower unit and at the other end to the second section interface of the main test pipeline 1. In this embodiment, the outside of the main pipeline is sealed with a flange cover plate, but it still has the ability to be expanded later, and other specifications of blowers or other equipment can be added. The outlet branches of both blower units are connected to the main pipeline through flange interfaces. The first electric butterfly valve 2.1 connects the main pipeline 1 and the first transition bend 2.2. The first wafer check valve 2.3 connects the first transition bend 2.2 and the first outlet pipeline 2.5. Connecting the magnetic levitation blower unit, the first vent valve 2.4 serves as a backup vent valve and is installed on the first outlet pipe 2.5. Temperature and pressure sensors are installed on the first sensor interface 2.6 to measure the outlet air temperature and pressure inside the pipe. The outlet pipes of the two blower units are consistent, allowing simultaneous connection of two blower units. This avoids frequent disassembly and assembly of test pipes and other test fixtures when conducting long-term, phased performance tests on two devices in a short period. Meanwhile, the electric butterfly valve is an adjustable valve that works in conjunction with the flow regulating valve 8 on the main pipe. By adjusting the opening of the two valves separately, the on-site working conditions can be simulated more accurately.

[0023] In addition to the butterfly valve, the test pipelines of the first blower unit's outlet branch and the second blower unit's outlet branch are equipped with a wafer-type check valve. In this embodiment, when the test of this branch is stopped, a double seal is formed in the pipeline of this branch to avoid interference with the test data of other branches.

[0024] The test pipeline for the third blower head outlet branch and the third butterfly valve 4 are connected at one end to the blower head outlet and at the other end to the third section interface of the main test pipeline 1. The test pipeline for the fourth blower head outlet branch and the fourth butterfly valve 5 are connected at one end to the outlet of another blower head and at the other end to the fourth section interface of the main test pipeline 1. In this embodiment, one end of the third transition bend 4.1 is connected to the main pipeline 1 via a flange interface, and the other end is connected to the third butterfly valve 4.2. The third outlet pipeline 4.3 is used to connect the blower head and the third butterfly valve 4.2. The temperature sensor and pressure sensor are installed on the third transmission... On sensor interface 4.4, the air outlet temperature and pressure inside the pipeline are measured. The air outlet pipelines of the two blower heads are consistent, and two blower heads can be connected at the same time. With the two blowers, the frequent disassembly and assembly of test pipelines and other test fixtures are avoided when a total of four devices are subjected to long-term, phased performance tests in a short period of time. When the test of a branch is stopped, the butterfly valve is closed to complete the double sealing of the branch pipeline, so as to avoid interference with the test data of other branches. At the same time, the butterfly valve is a manual regulating valve, which works in conjunction with the flow regulating valve 8 on the main pipeline. By adjusting the opening of the two valves respectively, the design conditions of the blower head can be simulated more accurately.

[0025] Furthermore, the exhaust pipes of each blower are connected to the main exhaust pipes 1 of each section through flange interface structure, forming a complete pipeline; one end of the silencer 6 is connected to the main test pipeline 1, and the other end is connected to the exhaust pipe; in this embodiment, the flow regulating valve 8 is installed on the main pipeline 1 to adjust the gas flow and pressure of the main test pipeline; at the same time, each test branch shares the same silencer and exhaust pipe, effectively reducing the space occupied in the test site.

[0026] The test pipe of the blower unit's outlet branch is equipped with a corrugated pipe at the connection between the blower unit and the blower unit; in this embodiment, it can effectively compensate for the axial distance between the outlet pipe and the outlet pipe of the test unit, as well as the thermal expansion during the test.

[0027] A flow sensor is installed on the main test pipeline 1, with additional sensor mounting holes reserved. The test pipelines of the first blower unit outlet branch and the first butterfly valve 2, the test pipelines of the second blower unit outlet branch and the second butterfly valve 3, the test pipelines of the third blower head outlet branch and the third butterfly valve 4, and the test pipelines of the fourth blower head outlet branch and the fourth butterfly valve 5 are all connected to the main test pipeline 1, and each blower outlet branch test pipeline is equipped with a temperature sensor and a pressure sensor. The air inlet of the blower head under test is connected to an air inlet fixture, which is equipped with an air inlet differential pressure sensor and a temperature sensor. In this embodiment, the flow sensor is installed on the flow sensor interface 1.2, which takes advantage of the length of the main test pipeline to measure the pipeline flow more accurately. At the same time, additional sensor mounting interfaces are reserved to facilitate the subsequent functional expansion of the test bench.

[0028] The main test pipeline 1 has a reserved expansion interface 7 sealed by a flange structure. In this embodiment, when the test bench needs to be further expanded, the sealing flange structure can be removed, the main test pipeline can be extended, and a new test blower unit air outlet branch can be added, which can more easily meet the testing needs of the new equipment.
