SU957177A1 - Device for controlling water distribution in multi-reservoir water supply systems - Google Patents

Description

one

The invention relates to an agricultural water supply and is intended for automatic water distribution and control of a pump installation in multi-reservoir water supply systems.

A known control system for a pumping unit is based on the difference in water levels in a pressure tower, for example, an automation system of the type SAUNA, OIMO, PET-5102, SCHEP-5801 L.

This automation system works with float or contact level sensors that are installed inside the water tower.

Communication between the level sensor and the control station is via a low-voltage overhead or cable line.

However, this automation system is intended only for water supply systems with one water tower located at the command height,

therefore, it is not suitable for multi-reservoir systems.

The closest to the technical essence of the invention is on-off control in circuits with a water-pressure reservoir, where the pump is turned on and off depending on the water level in the latter 2.

The disadvantages of the known system are bulkiness, material consumption and the need to build an expensive water reservoir.

In addition, it does not meet the requirements of automating multi-tank water supply systems.

The aim of the invention is to expand the field of application of the device.

Claims (2)

The goal is achieved by the fact that the device containing a level sensor, an output connected to a pump unit control station hydraulically connected to 95 tanks, has level controllers placed in the tanks, and a tank that is highest in height is parallel to the level controller an upper pressure limiter, in the cavity of which a level sensor is located, the upper pressure limiter being hydraulically connected with all re-. Tanks. The drawing shows a diagram of the proposed device. Inside tanks 1, automatic controllers of relay level 2 are installed. In addition, inside the highest reservoir, the height is located at the end of the pressure pipe, parallel to the controller 2, the upper pressure limiter 3 is installed. Inside the housing, the latter is a contact level sensor k, which is connected by an electric transmission line 5 to control station 6. The upper pressure limiter is provided with an actuator that allows water to flow from the pressure pipe to the body only when the pressure in the pipeline increases to a predetermined value. The pump unit 7 supplies water through the pressure pipeline 8 to the tanks 1 of the water supply system. In all tanks, using a regulator of relay 2, a regulating volume is established, KO.TO ry is selected depending on the load on the watering station (water consumption). When the regulating volume of water in any of the tanks 1 of the system is used up, the shut-off valve of the regulator 2 opens. As a result, water flows from the upper limiter 3 casing to the conduit 8 to the accumulation tank 1. When the upper pressure casing drops to the lower level, the lower the sensor contact C level and the corresponding signal through the electric line 5 enters the control station 6. The pump unit 7 turns on and the water supply via the pipeline B to the tank 1 is resumed. After filling the latter with water to the upper level, the shut-off valve of the regulator closes 2. If the control volume of water in the other tank is consumed in the perird of filling one tank, the water flow will continue until all the emptied tanks are full. After filling all the empty tanks 1, the pressure in the pressure pipe 8 rises to the set value. The boundary pressure valve 3 of the upper pressure is opened and the body of the latter is filled with water. When the housing is filled, the upper level C contacts of the sensor are closed, and the electrical signal on line 5 enters the control station 6. The pine unit 7 is turned off and the water supply to the system is stopped. The proposed system of automatic control of the ac unit in water mains has a simple scheme of operation. All tanks of the system, regardless of the location in terms of distance and height, have the same value for water distribution and control of the pump unit. In the proposed automation system, all tanks of watering points are used, i.e. a water-pressure reservoir is required, it means that construction materials, means, and also operating costs are saved, because water is pumped directly into the reservoirs of water points, i.e. there is no rise of water to an extra height. In addition, very simple hydraulic devices are used for automation, and the hydraulic connection of all tanks and automatic water distribution between them, depending on the load on the watering station, allows for more efficient use of valuable drinking water. Claims An apparatus for controlling water allocation in multi-reservoir water supply systems, comprising a level sensor, output connected to a pump unit control station, is hydraulically connected to tanks, characterized in that, in order to expand the field of application of the device, it contains level controls
