Description
папами-пульсаторами 4 - с рабочей полостью 11 и аккумул тором 16. Все элементы системы размещены в корпусе 17, который навешен на захваты 18 машины.Papas-pulsators 4 - with a working cavity 11 and a battery 16. All elements of the system are placed in the housing 17, which is hung on the grippers 18 of the machine.
Работает гидравлическа система следующим образом.The hydraulic system works as follows.
После опускани оборудовани на грунт насос гидропривода 1 заполн ет аккумул тор 2 и п-ри достижении требуемого давлени распределителем поток жидкости направл етс в верхнюю полость цилиндра 3 и в полость аккумул тора 16. Из полости аккумул тора 2 жидкость поступает в рабочую полость 11 и через дроссель 10 в надклапанную полость 9. Жидкость , заполн юща под давлением надклапанную полость 9, преодолева усилие пружины 8, открывает разгрузочный клапан 7, через который идет на слив. При падении давлени в надклапанной полости 9 открываетс клапан 5 управлени и клапаны-пульсаторы 4, через которые ЖИДКОСТЬ из рабочей полости 11 поступает в цилиндр поршн 15. Дл предупреждени преждевременной посадки пульсаторов 4 и клапана 5 в схеме предусмотрен след щий подпружиненный стержень 6. При перемещении порщн 15 на величину импульсного хода давление в цилиндре и в рабочей полости 11 падает , происходит закрытие клапана 5 и клапанов-пульсаторов 4, а поршень 15 открывает сливное отверстие дроссел 14, что ведет к возвращению элементов системы в исходное положение.After the equipment is lowered to the ground, the pump of the hydraulic drive 1 fills the battery 2 and, when the required pressure reaches the distributor, the fluid flows into the upper cavity of the cylinder 3 and into the cavity of the battery 16. From the cavity of the battery 2 the liquid enters the working cavity 11 choke 10 into the supravalve cavity 9. The fluid filling the pressure above the valvular cavity 9, overcoming the force of the spring 8, opens the unloading valve 7, through which it goes to the drain. When pressure drops in the valve chamber 9, the control valve 5 and the pulsator valves 4 open, through which LIQUID from the working cavity 11 enters the piston cylinder 15. To prevent the pulsators 4 and valve 5 from premature fit, the valve has a spring-loaded rod 6. When moving the pressure in the cylinder and in the working cavity 11 drops by the magnitude of the impulse stroke; the valve 5 and the pulsator valves 4 are closed, and the piston 15 opens the drain port of the throttle 14, which leads to the return of the elements s system to its original position.
