1應用範圍
裕祥集中潤滑給油裝置乃爲滾珠軸承、滑動軸承、平面滑軌、圓形滑軌、
線性滑軌、凸輪、齒輪、鏈條…等機構而設計的。
裕祥集中潤滑給油裝置適用於各式工作母機，如車床、銑床、壓床、刨床、
磨床…等，它可以同時對不同機器的潤滑點作潤滑。
YET-R 機型潤滑油黏度介於 30 ~ 250 cSt，並請選用新的油料。
YET-R1 最大出油量為每分鐘 200 ml。
YET-R2 最大出油量為每分鐘 150 ml。
YET-R1 的設定壓力為 7 kgf/cm2， YET-R2 的設定壓力為 15 kgf/cm2。為保
護週邊設備，設有釋壓閥來固定潤滑時的壓力。YET-R2 可以使用容積式分配
器，配合脫壓裝置 ,在間歇時間舒解油管內的油壓。
爲了在油不足時能使被潤滑的機器得到保護，YET-R 注油機可與機械的控
制系統連接將機器停止。此外，YET-R 裝有警報器，可在油位到達下限前發出
信號通知操作人員。亦可將注油機和電腦或應用系統聯機以加強警報功能。
YET-R 的設計是以間歇方式潤滑。在這些機台上都附有間歇時間調整鈕可
以設定間歇時間間隔。YET-R 附有潤滑時間調整旋鈕可以設定潤滑時間。
對YET-R 注油機：間歇時間可設定由小於 1分鐘到 180 分鐘，潤滑時間設
定範圍亦可由 2到180 秒，最大吐出量爲 200ml / min(也就是 3.33 ml / sec)。
注意：潤滑與間歇時間的設定值一般誤差約在 20%左右，建議客戶在設
定潤滑和間歇時間時數字在 5以上，最好以 5的倍數遞增（潤滑時間和
間歇時間在 5以下可能會出現較大誤差）。

開機潤滑是以潤滑模式啟動，亦即在注油機一接上電源啟動時即先對各個
潤滑點進行一次供油潤滑，然後再依設定好的時間值運作。因爲油在機器上太
久沒運轉可能會蒸發或流失掉，開機潤滑模式可以避免因上述情形而造成傷
害。
開機間歇模式則是一接上電源就進入間歇模式。本公司注油機以開機潤滑
模式設定出廠 (除非客戶指定)。
YET-R 的間歇時間可由 1分鐘到 180 分鐘。 YET-R 注油機間歇時間歸零爲
30 秒，轉動間歇時間設定旋鈕(圖十)在間歇指示燈(綠燈)會亮。

The orange light powers on when lubrication(Fig.10). Use lubrication time setting
knob to set oil time, of which the range is 2~180 sec. When the knob returns to zero, the
time is 2 sec.
3-3 Intermittent time
Two start modes: lubrication mode & intermittence mode.
Lubrication mode: Start lubricating first after power on. Because the oil may not
evaporate or be lost when it is not running for a long time on the machine, the start-up
lubrication mode can avoid damage caused by the above situation. When lubricant is
nor running on the machine for a long time, the lubricant may be lost. Lubrication mode
can avoid the damage caused by this.
Intermittence mode: Start from intermittent time after power on, which is factory
setting.
YET-R intermittent time:1~180 min. When the intermittent time settign knob
returns to zero, the time is 30 sec. When turn the knob, the green light on.
Warning! The general error of setting time is about ±20%.
Warning! Intermittent time must be more than 5 times of the lubrication
time.3 mins Min. intermittent time is suggested.

20 - 23
3-4 Forced lubrication
Push the “FEED” button in anytime, start to forced lubricate immediately, and the
orange indicator light on.
3-5 Refilling lubricant
The lubricant level must between LOW and HIGH line.
When lubricant is insufficient, YET-R will stop operating and send a signal (2-4.2).
Warning! Never use used lubricant.
4 Maintenance
iSHAN centralized lubrication system is easy to maintain. The reservoir must be
cleaned before installation and in service time so clean the reservoir regularly. If there is
any impurity or oil sludge found at the bottom of reservoir or on the strainers of the
lubrication unit, disconnect the product from main power supply and take off the
reservoir by removing 4 screws on the corners. After the reservoir is cleaned, assemble
it to the lubrication unit.
