It would seem, for what in modern life such an outdated type of equipment is needed? However, you will remember with gratitude about it when there is a power outage. Electricity is not necessary for a manual water pump to work at all, because they supply water only when people act on them.
Application of a manual water pump to give
For this simple adaptation you can come up with a lot of tasks. For example, with its help you can quickly and conveniently plant the plants on the site. Often outside the city they are used and as pumps for pumping water into the house, where it is spent for household and household needs.
One can not help recalling the benefits of such a pump when it is necessary to deliver water to the greenhouse . As you can see, a lot can be invented for the use of this unit in the conditions of the city.
Varieties of hand water pumps
All manual mechanical water pumps are divided into piston, vane and rod. Piston pumps are used for pumping water from a well or well, a depth of not more than 7 meters.
If the water lies at a greater depth, you already need a rod-type manual water pump for the well. The device looks like a piston, only the length of the cylinder is larger, which creates a stronger vacuum discharge, and water is delivered from deep underground layers.
And the third kind of the water pump on a manual draft - winged. At the outlet, it has a pressure of 2 atmospheres, so that water can be delivered up to a height of 9 meters. The device of such a pump assumes a "wing" with 4 valves, a lever, a shaft, a suction part and a lid. This type of pump provides a constant current of water.
Choose between these three pumps, taking into account the type of water source, the number of occupants, the amount of water consumed and the hydraulic resistance in the plot.
