Description
6 по трубопроводу 11 в штоковую полость гидроцилиндра 9 сервоуправлени , поршень которого перемеш,аетс вправо вместе с золотником распределител 2. Жидкость от насоса 1 поступает в штоковую полость гидроцилиндра 3 стрелоподъемного механизма, и стрела опускаетс .6 through the pipeline 11 into the rod cavity of the hydraulic cylinder 9 of the servo-control, the piston of which is mixed, to the right together with the spool of the distributor 2. The liquid from the pump 1 enters the rod cavity of the hydraulic cylinder 3 of the boom-raising mechanism, and the boom is lowered.
При включении рычага клапана 7 вправо золотник 15 перемещаетс вниз и направл ет поток жидкости от насоса 6 по трубопроводу 10 в поршневую полость гидроцилиндра 9 сервоуправлени , поршень которого перемещаетс влево вместе с золотником распределител 2. Жидкость от насоса 1 поступает в поршневую полость гидроцилиндра 3 стрелоподъемпого механизма, и стрела поднимаетс .When the lever of the valve 7 is turned on, the spool 15 moves downwards and directs the fluid flow from the pump 6 through the pipeline 10 into the piston cavity of the hydraulic cylinder 9 of the servo-control, the piston of which moves to the left together with the valve of the distributor 2. The liquid from the pump 1 enters the piston cavity of the hydraulic cylinder 3 of the lifting mechanism and the arrow rises.
Применение гидроцилиндра 9 сервоуправлени дл возвратно-поступательного перемещени золотника распределител позвол ет снизить давление управлени за счет соответствующего подбора диаметров поршн и штока.The use of a hydraulic cylinder 9 servo-control for the reciprocating movement of the distributor spool reduces the control pressure by appropriate selection of the diameters of the piston and rod.
Предмет изобретени Subject invention
Гидравлический привод крановых механизмов , содержащий насосы, гидродвигатель, клапаны сервоуправлени , распределитель, бак,Hydraulic drive of crane mechanisms, containing pumps, hydraulic motor, servo control valves, distributor, tank,
фильтр и трубопроводы, отличающийс тем, что, с целью снижени давлени в системе управлени и использовани стандартных распределителей с ручным управлением, распределитель выполнен с гидроцилиндромfilter and pipelines, characterized in that, in order to reduce pressure in the control system and use standard hand-operated valves, the valve is made with a hydraulic cylinder
двойного действи , шток которого соединен с золотником распределител , а поршнева и штокова полости подключены трубопроводами к клапану сервоуправлени .double action, the rod of which is connected to the distributor spool, and the piston and rod cavities are connected by pipes to the servo-control valve.
