METHOD OF CONTROLLING WATER TANK PUMPING ASSEMBLY LAYOUT AND WATER RESERVOIR PUMPING ASSEMBLY DELIVERY ARRANGEMENT Russian patent published in 2019 - IPC F04D15/00 E03B1/00 

FIELD: pumps.

SUBSTANCE: group of inventions relates to the field of pumping units. In the method, the set value of the pumping assembly is determined based on the offset value reduced by the component, which is a function of the difference between the actual water level and the predetermined water level in the water reservoir. Difference is weighted by means of automatically controlled proportional gain. Amplification factor is adjusted each time when a predetermined level of water in the reservoir and / or a predetermined time interval is reached. In the method of controlling multiple supply pumping assemblies of a water reservoir, all pumping assemblies provide supply for the same water reservoir. Set value is supply. Each set value is determined according to the method described above, and corresponding set values are scaled according to following formula: q_set, i = s_iG₀−S_iG₁(h−h_min), where s_i denotes a scaling factor regulating the value of water delivered by the i-th pumping assembly, and i denotes the corresponding pumping assembly. Pump inlet assembly of water reservoir includes at least one water pump and control device to control said at least one pump according to above described method.

EFFECT: method is provided to control one or more pumping assemblies of a water reservoir without compromising system safety.
