How to make a water pump
A workshop on how to make a powerful, low-voltage water pump for various needs. For example, deflate a barrel of water for watering plants, etc. The pump works fine with a 12 V battery, which is its primary advantage.And a plug for a pipe of 50 mm.In the plug we place holes for the engine: two for mounting screws, one for the shaft.We drill and deburr.Now you need to cut off the bottom part. Mark up a straight line rotating the stub.Saw off with a hacksaw.Using sandpaper, we align the surface and get rid of the burrs.Also cut the skirt of the adapter in the same way.Combine the adapter with a plug to check the flatness of the adjoining surfaces.Take a small piece of PVC pipe 20 mm in diameter and cut it under an angle of about 45 degrees. Next, you need to create a rounded surface of the cut edge. To do this, wrap the adapter with sandpaper and grind the edge of the tube to obtain the shape of a circle.In the adapter, make a hole under the tube.Glue the tube into the hole with epoxy-based glue.Take a disposable syringe and check how tight it is on the motor shaft.If it's tight, then that's fine, that's what we need.Cut off the tip of the syringe.For the manufacture of the impeller is necessary to cut a square from aluminum. In it to make a hole, such that the skirt of the syringe is tightly dressed.We mark the square into 9 parts.Draw the diagonals in the squares through the cage. See photo.Cut corners with scissors for metal.Fold the squares. See photo:From an unnecessary camera from a bicycle or car, cut a gasket under the engine.Take a motor with screws.Dress the gasket,we put on the cap and fix all this with screws.Then we dress the cut papochka from the syringe to the motor skirt.Then we dress the impeller. Everything should sit very tightly. It will not be superfluous to glue everything with epoxy-based glue.Cut out a ring from a 50 mm diameter pipe, about 10 mm wide. We insert half into the adapter. The part that is visible through the hole is deleted.Putting the pump together.Glue the joint with hot glue.Put the corner fitting on top of the tube.And we glue an adapter with a diameter of 32 mm to 20 mm into the adapter. Fix on hot glue.Insert the handset.This will be a water intake.It's time to test. For reliability, you can mount the motor on the board, tied with a metal clamp. We will connect the system to a voltage of 12 V. We lower the intake pipe into a container with water. We are energizing and the pump is working.
