Multifunctional fluid mechanics experimental device

Abstract

The invention discloses a multifunctional fluid mechanics experimental device. The multifunctional fluid mechanics experimental device comprises a water source, a reynolds experiment pipe, a Bernoulli experiment pipe, an on-way resistance pipe, a local resistance pipe, a valve local resistance measuring pipe, a pitot pipe, a Venturi meter, an orifice plate flowmeter, a piezometer pipe, a measuring groove, selection valves and adjusting valves; the reynolds experiment pipe, the Bernoulli experiment pipe, the on-way resistance pipe, the local resistance pipe, the valve local resistance measuring pipe, the Bernoulli experiment pipe, the venture meter and the orifice plate flowmeter form into six testing pipe sections in a parallel mode; the selection valves are installed at inlet sections of the experiment pipe sections; the inlet sections of the experiment pipe sections are connected with a water source through the selection valves; the adjusting valves are installed at outlet sections of the experiment pipes; the outlet sections of the experiment pipes are connected with the measuring groove through the adjusting valves. According to the multifunctional fluid mechanics experimental device, the separated experiment pipelines are integrated in one experiment device, frequent assembling and disassembling is avoided, leakage is reduced, the experiment pipelines are clear at a glance and not easy to mix, and user understanding of the experimental principle is facilitated.

Description

technical field

[0001] The invention belongs to the field of test instruments, in particular to a multifunctional fluid mechanics test device. Background technique

[0002] Existing fluid mechanics experimental devices or experimental pipelines are scattered, and a set of experimental devices can only conduct one kind of fluid mechanics principle test. When performing other tests, it is necessary to disassemble the test pipe section and then install the corresponding test pipe section, because most of the test pipe sections are made of glass products. , It is extremely inconvenient to disassemble and install, and it is easy to cause water leakage and pressure leakage or damage to the pipe section. The entire replacement process is cumbersome, time-consuming and laborious. There are many experimental pipelines, and it is easy for students to be confused when disassembling and replacing them, which will affect the experimental results and students' understanding of various pri...
