The water pump – very necessary thing in economy. It is especially useful to gardeners and gardeners. Of course, it is always possible to get motor-pump in shop, thereby having saved itself from need to run to and fro on the site with water. Nevertheless, after all it is possible to build the hands the pump, thereby having saved the considerable sum of money.
It is required to you
- - brake chamber;
- - metal balls;
- - copper tubes;
- - epoxy glue;
- - inner tube.
Instruction
1. Take the brake chamber which has already served the term, and disassemble it. Further it is necessary to muffle all wells. Leave only opening under rod (it will be upper part). Do in opposite part of the camera in the bottom of several holes under valves.
2. Take small piece of the copper or brass tube having thick walls. Pick up ball (metal) with the same diameter that it was a little more, than the inside diameter which the tube has. Drill out on half of length tube by means of the drill having the large diameter, than ball.
3. After that place across opening and in pipe ball, and from above solder wire piece. Thus, you build inlet valve. In the course of suction pressure from below will lift ball, opening aperture. The opening will be closed by means of ball with pressure from above, and the wire which has been soldered from above will not allow it to jump out of pipe.
4. Make outlet valve in the same way, as well as inlet. Only between ball and the soldered wire it is necessary to place spring - it will press ball to opening. The spring will contract pressure from above because of what the valve will open. Further it is necessary to insert valves into openings and to put them on epoxy glue.
5. Further it is necessary to take cut of inner tube. Cut out from it circle (it will serve as membrane) on diameter of the brake chamber. Make opening in the middle of circle then paste to it on both sides on washer. The pin with thread needs to be inserted into these washers, after that to tighten it by means of nuts.
6. Now paste circle to bottom of the brake chamber. Connect part of the brake chamber above to the lower part, having passed rod from above in opening. For bigger convenience it is recommended to solder the handle to rod.
