Description
Technical Field
The invention belongs to the technical field of automatic control devices of fluid mechanics, and particularly relates to a corrosion-resistant and high-temperature-resistant fluid medium pulse test device.
Background
The fluid medium pulse test is a test method for simulating the working state of equipment such as pipelines, valves, pressure vessels and the like under the conditions of impact, pressure fluctuation and the like. This test is typically used to detect the performance and reliability of the device under extreme conditions, as well as to predict its useful life.
In the test process, the tested equipment is usually subjected to a transient fluid pulse, and parameters such as pressure, flow, speed and the like can be adjusted within a certain range. In the test process, the working state of the equipment can be monitored in real time, and the equipment comprises the changes of parameters such as pressure, flow, temperature and the like, and the responses such as vibration, displacement and the like of the equipment. These data can be used to evaluate the performance and reliability of the device, as well as predict its useful life.
The fluid medium pulse test is typically used in several cases:
1. pipeline system: the piping system is prone to problems such as leakage and breakage when subjected to shock, pressure fluctuations, and the like. The performance and reliability of the pipeline system can be detected and the service life of the pipeline system can be predicted through a fluid medium pulse test.
2. And (3) a valve: valves are an important component in a piping system, and their performance and reliability directly affect the normal operation of the piping system. The sealing performance, the switching performance and the like of the valve can be detected through a fluid medium pulse test, and the service life of the valve can be predicted.
3. A pressure vessel: the pressure vessel is easy to crack under the extreme working conditions of high pressure, high temperature and the like. The sealing performance, the bearing capacity and the like of the pressure vessel can be detected through a fluid medium pulse test, and the service life of the pressure vessel can be predicted.
In summary, the fluid medium pulse test is an important device performance test method, and can be used for detecting the performance and reliability of the device under extreme working conditions and predicting the service life of the device. During the test, attention is paid to the problems in terms of test conditions, equipment preparation, parameter control, parameter monitoring, result analysis and the like.
However, the current pulse power units for testing are single diaphragm (plunger) and rotary direct drive media pumps. The single diaphragm (plunger) has the disadvantages of safety in leakage and risk of liquid mixing, high corrosion, high temperature and Gao Yiran of a rotary direct-driven individual pump, incapability of improving the leakage of a shaft sealing valve, high temperature resistance, efficiency reduction and the like, and influences the environment or the quality of test products.
Most of traditional equipment adopts a single-layer or double-layer cavity structure, and once the cavity structure is extruded by excessive pressure, medium carried in the double-layer or single-layer cavity is easy to mix or overflow, so that the problems in aspects of parameter control, parameter monitoring, result analysis and the like of the whole device are influenced, namely the final measurement result of an experiment can be influenced.
