INFLUENCE THE START-UP PUMP ELECTRIC DRIVE PARAMETERS ON PRESSURE IN THE WATER SUPPLY SYSTEM AS LINES WITH THE DISTRIBUTED PARAMETERS

In article it is shown that at start-up of pumps electric drives there is an essential increase of pressure in water supply systems. It is caused by wave processes in a water supply system as lines with the distributed parameters. This phenomenon can cause frequent rushes in networks at their deterioration. It is shown how means of the electric drive it is possible to reduce pressure amplitude in a water supply system depending on its extent.
