Embodiment Construction

[0019] In order to facilitate the understanding of the present invention, the embodiments of the present invention will be described below in conjunction with the accompanying drawings. Those skilled in the art should understand that the following description is only for the convenience of explaining the present invention, not as a specific limitation on its scope.

[0020] The flow meter durability test device of the present invention includes a low-temperature water tank C1, a high-temperature water tank H1, and a first experimental pipeline and a second experimental pipeline. Among them, the high-temperature water tank H1 is equipped with a heater H12, and its maximum temperature can reach 90°C. The temperature stability of the high-temperature water tank H1 can be better than ±1°C; The temperature is controlled below ℃, and its temperature stability can be better than ±1℃. In the test pipeline part B of the first experimental pipeline, 1 to 3 instruments under test can be ...

Abstract

The invention discloses an alternation type flow instrument durability experimental facility. The alternation type flow instrument durability experimental facility comprises at least one water tank, at least one water pump matched with the at least one water tank, a first experimental pipeline and a second experimental pipeline, wherein a plurality of instruments to be tested are arranged in the first experimental pipeline, and a plurality of instruments to be tested are arranged in the second experimental pipeline. According to the alternation type flow instrument durability experimental facility, the design that two water supply systems and the two experimental pipelines are combined is adopted; during a whole durability test, the two sets of water supply systems are kept to be in a stable operating condition and are prevented from being impacted by an abrasion test, the reliability of the test is guaranteed, and the service life of equipment is guaranteed; meanwhile, the instruments to be tested can be converted to be in different operating states rapidly, high abrasion strength is achieved, and both the temperature alternation mode and the flow alternation mode are achieved.

Description

technical field [0001] The invention relates to a durability test device, in particular to an alternating instrument durability test device. Background technique [0002] Flow measurement is one of the components of measurement science and technology, and it is closely related to national economy, national defense construction and scientific research. Doing this work well plays an important role in ensuring product quality, improving production efficiency, and promoting the development of science and technology. Especially in today's era of energy crisis and increasing automation of industrial production, flow meters play an important role in the national economy. position and role are more obvious. [0003] At present, flow meters need to be used in various environments. In order to understand the performance of flow meters under various environmental conditions, it is usually necessary to conduct durability experiments on flow meters in a simulated environment. The durabi...
