Abstract
The utility model provides a fluid pressure intensity tester comprising a fluid pump, a fluid pipeline, and pressure intensity sensors. The fluid pipeline is formed by connecting at least two segments. The diameter of each segment is increased successively. Each segment of the fluid pipeline is connected with a pressure intensity sensor. A segment, with the least diameter, of the fluid pipeline is connected with the fluid pump. When a test is performed, one end of a signal line is connected with a data collector while the other end of the data line is connected with a pressure intensity sensor; the data collector is connected with a computer through a USB data line; and an air pump is started and data of pressure intensity sensors on each segment of the fluid pipeline is recorded by software in the computer. The fluid pipeline is divided into a plurality of segments with different diameters. Pressure is recorded automatically by the pressure intensity sensors on the segments. Different pressure values are recorded in segment through the fluid pipelines with different diameters. Therefore, with the fluid pressure intensity tester, experimental phenomena can be observed by operators in a visualized manner, and accurate counting and easy manipulation can be achieved.
Description
Technical field
The utility model relates to a kind of tester for measurement gas flow velocity and pressure relation, belongs to physics experiment teaching technical field.
Background technology
In junior middle school physics teaching, relate to pressure and the flow velocity relation related content of fluid, and the experiment illustration that discussion both sides relation is quoted, most for to carry out indirect demonstration by some phenomenon, as blow air between two pieces of paper, the floating of close, the table tennis mutually between two paper and blow coin and skip obstacle etc.In all experiments, lack the experiment that directly shows data, student understands comparatively difficulty.Along with digital experiment instrument is quoted, utilize pressure transducer to carry out DATA REASONING to the pressure of gas, make this experiment quantize there has been certain basis.But to better bring into play the effect of sensor, also need the empirical model that coordinates with it, therefore, develop a kind of necessary with the matching used fluid pressure tester of sensor.
Summary of the invention
The deficiency that the utility model exists for fluid pressure experimental technique in existing teaching, provides a kind of and can observe intuitively experimental phenomena, counts fluid pressure tester accurate, simple to operate.
Fluid pressure tester of the present utility model, adopts following technical solution:
This fluid pressure tester, comprise fluid pump, fluid line and pressure transducer, fluid line has at least two sections to be formed by connecting, and the diameter of each section increases successively, in each section of fluid line, be all connected with pressure transducer, on fluid line, one of diameter minimum section is connected with fluid pump.
During experiment, by signal wire one end connection data collector, the other end connects a pressure transducer; Data acquisition unit is connected to computing machine by usb data line, and booster air pump, by the data of the upper pressure transducer of each section of software records fluid line in computing machine.
The utility model makes fluid line be divided into some sections of different-diameter, by the pressure transducer on every section, automatically record pressure size, can divide segment record different force value by the different fluid line of diameter, can observe intuitively experimental phenomena, counting accurately, simple to operate.
Accompanying drawing explanation
Accompanying drawing is one-piece construction schematic diagram of the present utility model.
In figure: 1, air pump, 2, fluid line, 3, plug, 4, pressure transducer.
Embodiment
As shown in drawings, fluid pressure tester of the present utility model mainly comprises that air pump 1, fluid line 2 and pressure transducer 4(can be also relative pressure transducers), it (is three sections in accompanying drawing that fluid line 2 is formed by connecting by three sections, also can be more than three sections), the diameter of three sections increases successively, one section of diameter minimum is connected with air pump 1, in each section of fluid line 2, all by plug 3, is connected with pressure transducer 4.Plug 3 is fixed on the middle part of each section.Plug 3 can adopt fast plug.Fluid line 2 is and is threaded with fluid line 2 with air pump 1, plug 3, is convenient to assembling and dismounting.Air pump 1 also can be replaced by other fluid pumps such as water pump, oil pumps.
During experiment, by signal wire one end connection data collector, the other end connects pressure transducer.Data acquisition unit is connected to computing machine by usb data line, booster air pump, computing machine is by the data of the pressure transducer on software records fluid line 2 each sections.By pressure transducer, automatically record pressure size, can be by the different different force value of each segment record of diameter on fluid line.
