To the outlet fitting 43 of the device, the consumer's line and elements of the water supply system are mounted, depending on the tasks.

The device allows you to compactly equip wellheads, caissons, pits and solves the problem of the optimal composition and combination of structural elements interconnected as part of this device by assembly operations that ensure structural unity and implementation of a device of general functional purpose (functional unity) necessary for organizing water supply to the consumer directly from a well, in one industrial product. In the water supply device, a constructive combination of parts of the device with the help of a collector 4 is implemented, characterized by the presence and interconnected functional purpose, as well as the mutual arrangement of elements, such as:

the base part 5, 6, 7 for sealing the casing pipe 16 of the well and interfacing with the collector 4 with the simultaneous introduction of the pressure line 17 into it and its direct connection in the collector 4 using the channel 40 with the volume of the hydraulic accumulator 1 and using the channel 41 with the consumer's line;

hydraulic accumulator 1 for constant duty as part of a water supply device for creating and maintaining a supply of water directly from the well, maintaining the necessary pressure in the consumer's line, as well as damping hydraulic shocks in the pressure line 17 and in the consumer's line;

plug (drain valve) 18 for draining water, if necessary, from all ground equipment, combined by a manifold 4, directly into the well;

pressure relay 22 for continuous monitoring of the water pressure supplied to the consumer's line, automation of the submersible pump;

pressure gauge 27 for additional visual control of pressure in channels 40,41 and pressure line 17 for operational monitoring of the condition and assessment of the performance of the water supply device as a whole.

The water supply device from the well works as follows.

The device is operated in conjunction with a submersible pump and a check valve (not shown) installed on the pressure pipe 17. The included submersible pump supplies water through the pressure pipe 17 to the channels 40, 41 of the collector 4, ensuring the filling of the accumulator 1 and the water supply to the consumer (consumers). In the absence of pressure in the line, the pressure switch 22 supplies power to the submersible pump, which provides the necessary flow-pressure characteristic, depending on the configuration of the consumer. When the use of water is stopped (for example, the closing of taps by the consumer), a pressure in the system is reached, which corresponds to the cut-off pressure of the pressure switch 22. In this case, a supply of water is created in the accumulator 1 at a pressure equal to the switch-off pressure of the relay 22. When the water is again drawn (for example, opening taps by the consumer), the accumulator 1 initially supplies the accumulated volume to the consumer's line, the pressure drops to the switch-on limit of the relay 22, power to the pump, the cycle repeats.

Thanks to the use of this device, the dimensions and weight of the equipment are reduced by reducing the length and complexity of the main pipelines; the main pipeline between the well and the accumulator is not required (absent). The implementation of the device with basic means of fixation directly to the massive casing pipe of the well reduces the possibility of vibrations of its parts, which positively affects the durability and reliability of its operation for its intended purpose for water supply. The composition of the structural components of the device and their connections for installation directly on the well has been optimized, with the possibility of simultaneously installing a submersible pump in the well and sealing the casing. It is not required to use supporting building structures specifically for the installation of a hydraulic accumulator, it is possible to
