Zusammenfassung:FIELD: mechanical engineering; cooling systems of internal combustion engines and water supply systems. SUBSTANCE: method comes to physical action onto liquid by providing or interrupting supply of liquid flow along bypass branch pipe from delivery branch pipe of pump into its inlet branch in direction of common flow in inlet branch pipe. Bypassing is done by signal from pressure transmitter by opening-closing valve with electromagnetic drive. Transmitter is installed on rear part of pump rotor vane, pressure in zone of its mounting is measured and bypass of liquid is carried out when surface pressure exceeds normal pressure by 10-15%, i.e. when cavitational appears. EFFECT: improved accuracy of regulation , elimination of cavitation. 1 dwgo
