pyHydraulic using PyQt5

Project description

pyHydraulic using PyQt5, built by Bruce Lee in Nanjing institute of technology



1.Under the same folder of hydraulic Sketcher, add the sample file test.json of oil circuit diagram. (*/w *)

Project description for pyHydraulic

The software package is to realize the visualization of the digital hydraulic oil circuit in the software interface. In the software, through this software package, we can easily connect the hydraulic components and sensors in the oil circuit diagram. It can help people to understand, diagnose and even predict the faults in the hydraulic system. It’s a bit like a digital twin, but it’s only two-dimensional.

I specially built a tool called “hydraulic Sketcher” for drawing oil circuit diagram, which is included in this package. Similar to Visio, it can draw the hydraulic schematic diagram simply.

Create social share component pyHydraulic based on github

1.Get started

Installation is easy:

$ pip install pyHydraulic

2.Run the hydraulic Sketcher to draw schematics

Hydraulic sketcher is a tool similar to visio.It has been integrated in this package. Type the following code to call the tool independently.

from pyHydraulic.hydraulicSketcher import hydraulicSketcher

Next, you’ll see the following software interface.

The tool itself is also based on the pyHydraulic package. However, there are still some functions to be improved. A tutorial on using the tool will be provided later in GitHub.


In the coming days, I will give the instruction documents to give you some instructions on how to draw the hydraulic schematic diagram and load it in the interface of the measurement and control system For more demonstrations, please click the website below.
