2. Make a pressing handle, find a steel pipe with a diameter of 3 cm and a length of 80 cm, weld a loose leaf at one end of 35 cm, and make a gap of 1 cm at the front end.
3. Manufacture of piston: Make one end of a 40 cm long 12 steel bar into a small hook of 1 cm, and bend the other end at 90 degrees. Install the piston and spring on the pull rod.
4, wellhead production, in China, the wellhead is fixed with cement, and the cylinder of this hydraulic well is at the wellhead and must be fixed firmly.
5. The installation of hydraulic well is now the most critical part, that is, installation. Put the piston pull rod made in advance into the cylinder, then connect the pressing handle with the cylinder, and finally connect the front end with the piston pull rod.
6. Weld the outlet of the hydraulic well. Now that it is installed, we will find an 8 cm steel pipe with a slope of 140 degrees at one end, and weld the slope side with the outlet of the hydraulic well.
7. After the experiment, let's try our results. Take a basin of water and pour it into the pipe of the pressure well. Now press the handle up and down hard to see if there is any water.
