Description
камеру, в которой перемещаетс клапан . Между другой ступенью и торцом седла размещены прокладки 12.the chamber in which the valve moves. Gaskets 12 are placed between the other step and the end of the saddle.
Пневматический ударный механизм работает следующим образом.Pneumatic percussion mechanism works as follows.
Поршень-ударник под действием сжатого воздуха совершает возвратнопоступательное движение в цилиндре и в конце рабочего хода наносит удары по хвостовику бурового инструмента не показан).Piston-drummer under the action of compressed air makes reciprocating movement in the cylinder and at the end of the stroke stroke strikes the shank of the drilling tool (not shown).
Изменение направлени подачи сжатого воздуха дл рабочего и холостого хода осуществл етс автоматически клапаном 8, Регулировка хода клапана производитс подбором прокладок , устанавливаемых между ступенью цапфы и торцом седла клапана.The change in the direction of compressed air supply for working and idling is carried out automatically by valve 8. Valve stroke adjustment is made by selecting gaskets installed between the trunnion stage and the end of the valve seat.
Выполнение воздухораспределительного устройства пневмоударного механизма со съемной цапфой позвол ет, производить регулировку хода клапана , что обеспечивает снижение расхода сжатого воздуха на 10-15%.The implementation of the air-distribution device of the air-impact mechanism with a removable pin allows adjustment of the valve stroke, which ensures a reduction of the compressed air consumption by 10-15%.
