Abstract
1. Система управления для режущего устройства высокого давления, содержащего канал для потока жидкости и канал для потока суспензии, содержащей взвешенные в жидкости абразивные частицы, причем поток жидкости и поток суспензии под давлением поступают к режущему инструменту так, что по меньшей мере часть подаваемого давления преобразуется в режущем инструменте в кинетическую энергию для создания высокоскоростного потока смеси жидкости и суспензии, причем режущий инструмент содержит смесительную камеру, в которую поступает поток жидкости и поток суспензии, причем давление во входной зоне определяется давлением потока жидкости, причем указанная система управления выполнена с возможностью приведения в действие или перекрытия потока суспензии в канале для потока суспензии посредством активации или деактивации энергетических средств расположенных выше по потоку указанной камеры, благодаря чему давление в канале для потока суспензии по существу равно давлению во входной зоне смесительной камеры, независимо от наличия или отсутствия потока суспензии. ! 2. Система по п.1, в которой давление в жидкости нагнетается насосом с постоянным напором. ! 3. Система по п.1 или 2, в которой энергетические средства содержат насос с постоянным расходом. ! 4. Система по п.3, в которой насос с постоянным расходом приводит в действие поршень, который, в свою очередь, нагнетает давление в потоке суспензии. ! 5. Система по п.4, в которой между насосом с постоянным расходом и поршнем расположен клапан, выполненный с возможностью избирательного прекращения подачи энергии от насоса к поршню. ! 6. Система по п.1, в которой в канале для потока 1. A control system for a high pressure cutting device comprising a channel for a fluid stream and a channel for a suspension stream containing abrasive particles suspended in the liquid, the liquid stream and the suspension stream being pressurized to the cutting tool so that at least a portion of the applied pressure is converted in the cutting tool into kinetic energy to create a high-speed flow of a mixture of liquid and suspension, and the cutting tool contains a mixing chamber into which the flow of liquid and a suspension stream, wherein the pressure in the inlet zone is determined by the pressure of the liquid stream, wherein said control system is configured to actuate or block the suspension stream in the channel for the suspension stream by activating or deactivating the energy means located upstream of said chamber, whereby the pressure in the channel for the flow of the suspension is essentially equal to the pressure in the inlet zone of the mixing chamber, regardless of the presence or absence of the flow of the suspension. ! 2. The system according to claim 1, in which the pressure in the liquid is pumped by a constant pressure pump. ! 3. The system according to claim 1 or 2, in which the energy means comprise a constant flow pump. ! 4. The system according to claim 3, in which a pump with a constant flow rate drives a piston, which, in turn, pumps pressure in the suspension stream. ! 5. The system according to claim 4, in which between the constant-flow pump and the piston there is a valve configured to selectively cut off the energy supply from the pump to the piston. ! 6. The system according to claim 1, in which the channel for flow
