Definitions

• the invention generally speaking , belongs to the field of applied electrical engineering, that is, the field of electrical machines, therefore the subject of the invention also extends into the field of construction, regarding also, mechanical engineering.
• the technical problem that is solved by the present invention consists of the following: Filling the suction hose or pipe of an electric or motor pump with water through the water filling hole without a non-return valve at the beginning of the suction hose or pipe that is immersed in the well.
• a non-return valve is changed once and thus the dimensions of the construction are reduced, as well as the application of the subject invention in some cases increases the flow of the pump.
• a centrifugal pump depending on the design, either has a self-priming of a few centimeters or none at all.
• the pump In order for the pump to be able to draw water from the maximum depth of the factory-declared suction, usually 8-10 m and less, the entire system, the pump and the suction hose must be filled with water before putting the pump into operation.
• a well-known system includes a centrifugal pump, a suction hose and a non-return valve at the beginning of the suction hose.
• the elimination of air from the system is done by pouring water into the system through the filling hole on the pump itself. Water is poured into the pump and suction hose with the help of a funnel into the opening for pouring, which is usually closed with a screw.
• a system that includes a hand pump is also known.
• the pump is connected to the three way connector located on the pipe of the hand pump via the non-return valve.
• Putting the pump into operation requires first that the hand pump draws water with its vacuum and then that the motor or electric pump is filled with water together with the suction pipe to the non-return valve. Water is poured into the pump and the suction pipe with the help of a funnel into the opening for pouring, which is usually closed with a screw.
• the self-priming diaphragm pump has a self-priming of several meters, usually 2 m .
• the diaphragm pump can draw water even without a non-return valve by creating a vacuum.
• the diaphragm pump can draw water from a depth of 8- 10 m .
• a non-return valve is necessary before the pump on the suction hose.
• the function of the non-return valve is when filling with water so that the water used to fill the pump and the suction hose does not fall into the well.
• the pump is installed next to a plunge pipe of a smaller section, usually it is a pipe from a hand pump. There is a water well under the broken pipe. Pushing the suction hose with the non-return valve is possible only if the non-return valve is of small dimensions.
• the small dimensions of the non-return valve are a bottleneck for the system, so there is a significant reduction in the flow of the system. For most pumps, this type of construction is unsuitable due to the size of the non-return valve.
• the non-return valve can also be installed behind the pump.
• the function of the non-return valve installed in this way is to release water from the pump in the flow direction when the pump is working, that is, to create a vacuum in the non-return direction so that the water does not fall into the well when the pump is not working. So, with this construction, when the check valve is behind the pump, the pump draws water when it is working and the water from the pump cannot fall into the well when the pump is not working. It is necessary to fill the system with water only the first time.
• the water from the well to the top of the pump was only separated at the beginning of the suction hose by a balloon.
• the balloon As the pump is at some height above the well, due to the weight of the water and the pressure the balloon is slightly protruding towards the well.
• the balloon By starting the pump, the balloon slowly shrinks and then begins to enter the suction hose. Further, the balloon enters the suction hose more and more and bursts at a certain pressure.
• the balloon bursts there is a column of water from the bottom of the well to the top of the pump.
• the pump is running smoothly because the balloon has burst. After switching off the pump, water cannot fall into the well because a non-return valve is mounted behind the pump.
