Rotary Cylinder

중공형 유압실린더 SYH 모델 형식 표기
는 아래와 같습니다.

SYH open-center hydraulic cylinder is 
model coded as follows.

Oil from the hydraulic unit flows 
through the ports of the cylinder and 
retracts or extends the piston,
actuating the chuck. Circulated oil 
runs through the sleeve body and 
rotary valve, eventually returning to the 
hydraulic unit through the drain line. 
The lock valve prevents loss of pres-
sure in an event of a power outage, 
maintaining grip force on the work-
piece. The relief valve prevents loss of 
force in an event thermal expansion.

유압유닛으로부터 공급받는 작동유가
실린더내부의 유압회로를 거쳐 피스톤을 
전진, 혹은 후진시켜 척에서 필요로 하는 
파악력을 제공합니다.
유압포트로 공급된 유압은 슬리브와
회전밸브를 통하여 실린더 내부로 공급
되어 피스톤을 작동시킵니다.
순환된 유압은 반대편 유압포트를 통해 
유압탱크로 복귀하는데 이를 내부 드레
인이라고합니다.
내부로 유입된 유압외에 회전체와 비회
전체의 조립틈새를 통해 베어링을 윤활
시키고 드레인 니플로 흘러 탱크로 복귀
하는데 이를 외부 드레인이라고 합니다.
로크밸브는 장비의 갑작스런 전원 off에 
의하여 공작물이 비산하는 것을 방지하
기 위하여 유압공급이 중단되었을 때
실린더 내부의 유압이 손실되지 않고 
일정시간동안 유지하는것이 주 목적입니
다. 릴리프 밸브는 일반적으로 감압밸브
라고 하며, 압축된 오일이 열팽창에 의하
여 극단적인 추력과 압력상승에 따른
실린더의 손상을 방지합니다.

SYH开放中心液压缸型号编码如下。

由液压机组供应的液压油通过油缸内
部的 液压电路压缩活塞,从而提供
卡盘所需的夹持力。 传到液压端口
的液压,通过套管和旋转阀传到油缸
内部,从而运行活塞。经过循环的液
压通过反方向的液压端口进入液压站
的过程叫做‘内部排油’。 除
了流入到内部的液压以外,通过旋转
体和无旋体之间组装的空隙润滑轴承
之后,通过排油接头返回贮油箱的过
程叫做‘外部排油’。 检验阀的主
要功能是为了防止装备在突然停电的
情况下加工产品飞散,从而在液压供
应被中断时,使油缸内部的液压不受
损,让液压维持一定时间。 泄放阀
一般称之为减压阀,防止被压缩的油
热膨胀而产生极端性推力和压力上升
而损伤油缸。

2-2 構造與操作

Never use this rotating cylinder with 
a vertical lathe. This rotating cylinder 
is not provided with an oil seal but 
employs labyrinth sealing between the 
sleeve body and the shaft so as to 
minimize leakage that occurs during
high-speed rotation. For this reason, 
when this rotating cylinder is mounted 
on a vertical lathe, a large quantity of 
oil will leak and the bearing will not be 
sufficiently lubricated, resulting in dam-
age to the rotating cylinder.

이 회전실린더는 고속회전시의 누유를 
최소화하기 위해 슬리브바디와 회전부 
사이에 라비렌스 구조를 사용하고 있습
니다. 완전한 밀봉구조가 아니기때문에 
실린더를 수직으로 사용하면 누유될뿐만 
아니라 베어링의 윤활도 할 수 없어 고장
의 원인이 되므로 절대 수직으로 사용
하지 마십시오.

该液压油缸为了在高速旋转时做到漏
油的 最小化,在套管体和旋转部之
间采用了迷宫式结构。因为不是完整
的密封结构,若使油缸处于垂直状
态,不仅会发生漏油,还会因为没有
轴承的润滑作用而成为故障的原因,
因此请千万不要使油缸处于垂直
状态。
