Abstract
Adjustable system for pumping water with self-priming pump consists of check valve (9), flexible plastic hose (7), water container (6), pump (10), power supply(16), drain hose (12) and it is necessary to fill the hose (7) with water over the switch (8) before exploitation and then lower the full system into the well (1).
Claims
1. Adjustable system for pumping water with self-priming pump is characterized by that the check valve (9) is connected to the flexible plastic hose (7) which is at the other end connected to the pump (10) with the container (6) at pump level and switch (8) with the help of power supply (11) fills the hose with water (7)(12) which is lowered into the well when it is full.
2. Movable system for water deflation with self-priming pump according to the request 1 and variants 4,5 is characterized by that it is powered (11) from the solar panel (16).

DISCLOSURE OF THE INVENTION
[0013] FIGS. 1 and 2 show cross sections of the well. Mark (1) stands for the level of water in the well and mark (2) is the wall of the well. In the FIG. 2 mark (2) stands for the level of water under the hand pump, mark (3) are the pipe holes of hand pump, (4) marks the pump pipe and (5) marks hand pump. The hand pump is totally unnecessary when you apply Adjustable system for pumping water with self-priming pump so you should dismantle the hand pump. The pipe is fixed in the ground and you do not make any changes on it.
[0014] FIG. 3 shows how the system looks and procedure of filling the plastic hose (7) with water. Procedure of filling the hose with water is described in the following way. Starting the pump (10) by pulling the switch (8), check valve (9) is opened and pump sucks residual air from hose. Motor or pump (10) start to suck in water from water container (6) because the difference of air pressure is several centimeters higher at the entrance pgh in other words density times gravitational constant times height of several cm. Awhile pump starts to pull water after some time there is a squirt at the exit. Hose (7) is full with water now. You should turn off the pump (10) now over the switch (8). It is impossible for water to drain because of the check valve (8). You should lower the hose into the well (1) or the pipe of hand pump (4) and then start the pump if it is necessary (8). The system is marked with two phases, the first one is charging hose with water and the second one is inserting hose into well and exploitation.
[0015] In the FIG. 3 water container (6) from a few liters is at level with the pump (10) and it can be raised several centimeters. You put the front end of the hose (7) in the container altogether with the check valve (9). The other end of the hose is connected to the pump (10) and the other end of the pipe is connected to the outlet hose (12) which does not have to be made from the same material as inlet hose (7). The pump is connected to the power source U1 (11) by cable and switch(8). You can use solar panel (16) as a power source. You should lower the system into the well (1) or the hand pump pipe FIG. 2 when it is full with water After that the system is for work. You use switch (8) to turn on and off the system. FIGS. 4 and 5 show the hose (7) when it is lowered into the well (1) or hand pump pipe (4). Solar panel (16) is used as a power source Electrical voltage U1 (11) of the system. Power of solar panels is small so it is possible to use low power pumps. Depending on the type of solar panel and pump type it is sometimes necessary break the electrical voltage of the pump and the simplest way to do this is by adding several rectifier diodes in line with the switch because we know that diode voltage drop is 0.7V.
[0016] FIG. 6 shows the look of the system after assembly. The check valve (9) is hitched at the beginning of the flexible plastic hose (7). The hose is connected to the pump (10) at the other end. The pump is also connected to the outlet hose (12). The pump is powered by switch(8) or by solar panel (16). FIG. 7 shows cross section of the check valve (9) and flexible plastic hose (7). One part of check valve (13) is hitched with spring (14). The second part of the spring pushes the rubber cylinder (15) which altogether with this part of the valve (16) do not allow water to return. Direction of the check valve is from free end to the hose (7).
[0017] FIG. 8 shows cross section of the flexible plastic hose (7) which is hollow from inside and it is filled with air or water.
INDUSTRIAL OR ANOTHER USE OF INVENTION
[0018] Adjustable system for pumping water with self-priming pump is (picture 6) altogether with container (6) and solar panel (16) suitable for irrigation of smaller areas in agriculture. There is no need for plumbing and system is movable so it is possible to dismantle it during the winter.
