The water supply device implements a constructive integration of parts of the device using a collector 4, characterized by the presence and interrelated functional purpose, as well as by mutual arrangement, such as:

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

hydroaccumulator 1 for permanent duty as part of a water supply device for creating and maintaining a reserve of water directly from the well, maintaining the necessary pressure in the consumer’s main line, and damping water hammer in the pressure main line 17 and in the mainline of the consumer;

 a stopper (drain valve) 18 for draining water, if necessary, from all the ground equipment, connected by a collector 4, directly into the well;

 pressure switch 22 for continuous control of the water pressure supplied to the consumer, automation of the work of the submersible pump;

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

The water supply device from the well works as follows.

The device is operated together with a submersible pump and a check valve installed on the pressure pipe 17 (not shown). The switched on 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 supply of water to the consumer (consumers). In the absence of pressure in the line, the relay 22 pressure supplies power to the submersible pump, which provides the necessary flow-pressure characteristic, depending on the configuration of the consumer. When water use ceases (for example, closing the taps by the consumer), the system pressure is reached, which corresponds to the shutdown pressure of the pressure switch 22. In the hydroaccumulator 1, this creates a supply of water under pressure equal to the shutdown pressure of the relay 22. When a new analysis of water arises (for example, opening of taps by the consumer), initially the accumulator 1 supplies the accumulated volume to the consumer’s main line, the pressure drops to the on limit of the relay 22, power to the pump, the cycle repeats.

Thanks to the use of this device, the size and weight of the equipment has been reduced by reducing the length and complexity of the main pipelines, the main pipeline between the well and the accumulator is not required (none). The implementation of the device with the basic means of fixation directly to the massive casing of the well reduces the possibility of vibrations of its parts, which positively affects the durability and reliability of its functioning for its intended purpose for water supply. Optimized the composition of the structural components of the device and their connections for installation directly on the well, with the possibility of simultaneous installation of a submersible pump in the well and sealing of the casing. The use of supporting building structures is not specifically required for the installation of a hydroaccumulator, it is possible to drain water directly from the water supply device into the well, if necessary, without flooding the adjacent territory. In this case, the device has in full the necessary functions for organizing the control of automatic operation of the pump, accumulation of water volume, pressure control, water drainage from the accumulator and main into the well, arrangement of caissons, sumps. All this significantly increases the reliability of the device as a whole, allows to increase the period of non-compliance and maintenance-free operation.
