Description
достаточное гидравлическое усилие на левый торец золотника, преодолевающее усилие возвратной пружины и удерживающее золотник в этом положении.sufficient hydraulic force on the left end of the spool, overcoming the force of the return spring and holding the valve in this position.
Слив рабочей л идкости в процессе пилени из гидродвигател 2 осуществл етс через трубопровод 18, а из полости возврата Б гидроцилиндра подачи пилы 3 - через трубопроводы 15 и 19 и далее - через гидрораспределитель 1.The working fluid in the sawing process is drained from the hydraulic motor 2 through pipe 18, and from the return cavity B of the saw supply hydraulic cylinder 3 through pipes 15 and 19 and further through the hydraulic distributor 1.
Дл прекращени пилени оператор отпускает руко тку управлени распределител 1, который автоматически устанавливаетс в нейтральное положение. Подача рабочей жидкости в рабочие органы прекращаетс . В св зи с этим прекращаетс дросселирование рабочей жидкости через дроссель 10, вследствие чего исчезает перепад давлений между торцовыми поверхност ми золотника 9, и последний под действием возвратной пружины перемещаетс влево. При этом происходит соединение полости Б гидроцилиндра 4 через трубопроводы 15 и 16 с гидроаккумул тором 7 и полости А этого гидроцилиндра через трубопровод 14 и 17 со сливом. Под действием давлени гидроаккумул тора 7 происходит автоматическое возвращение пилы 3 в исходное положение.To stop sawing, the operator releases the control knob of the distributor 1, which is automatically set to the neutral position. The supply of working fluid to the working bodies is stopped. In this connection, the throttling of the working fluid through the choke 10 is stopped, as a result of which the pressure differential between the end surfaces of the spool 9 disappears, and the latter moves to the left under the action of the return spring. When this occurs, the connection of the cavity B of the hydraulic cylinder 4 through the pipelines 15 and 16 with the hydraulic accumulator 7 and the cavity A of this hydraulic cylinder through the pipeline 14 and 17 with the drain. Under the action of the pressure of the hydroaccumulator 7, the saw 3 automatically returns to its initial position.
