3、注意： 在没有指示说明之前，请不要移动装载圈。当移动隔振器时必须使用装载 圈。Verify that you have the correct model for your payload. Payload weight MUST be within the recommended range, which can be found in the“Installation and Adjustment instruction book.检查该产品是否是你负载物所合适的型号。负载物的 重量必须控制在建议范围之内，参考范围请查阅安装与调试”说明书。Locate the three (3) leve

4、ling screws (A). Insert the leveling screws into thebottom of the isolator and place on a solid, level surface. Place the bubble level on the top plate and use the leveling screws to level the isolator.定位三个水平螺丝(A)。插入水平螺丝到隔振器 的底部以及放置隔振器到平稳的表面。把气泡水平 仪放置到顶板上并且用水平螺丝使隔振器水平方向 平衡。Carefully position payload

5、 on top plate so its center-of-mass (CM) is as close to center as possible. 小心放置负载物到顶板上以使它的最大值中心尽可 能地靠近中心处。Remove the three (3) red shipping collars (B). STORE SHIPPING COLLARS IN A SAFE PLACE AS THEY MUST BE USED WHENEVER MOVING ISOLATOR. Replace the screws into the holes to serve as Horizontal Pos

6、ition Indicators.移走三个红色装载圈(B)。把装载圈储存到一个 安全的地方因为每凡移动隔振器都必须要用到装载 圈。分别把螺丝插入孔洞来用作水平位置的指示 奥 TTIT oIf payload covers shipping collar holes, collars must be removed before placing payload. Take extra care when positioning payload without shipping collars attached. Do not replace screws as they may interfer

7、e with payload.Gap 一 should be equal on all sides如果负载物覆盖了装载圈的孔洞，载圈必须在没有放置 负载物之前移走。在没有加上装载圈的前提下放置负载 物时必须要多加小心。而且不要把螺丝插入孔洞因为他 们可能会干扰到负载物。Check the level of the top plate. The gap between the top plate and the isolator cover should be approximately equal on all sides.检查顶板的水平方向。顶板和隔振器盖的间隙在每一边 的距离都应该都是差不

8、多的。Reposition the payload, as necessary, to level the top plate. It is recommended that you re-install the red shipping collars if you need to reposition the payload (see Step 3). However, it is not necessary if you take extra care reposition the payload. Do not use leveling screws to level the top

9、plate. 如果有必要要重新移动负载物，使顶板的水平方向 对准的话。温馨提示：如果需要重新移动负载物的 话，最好重新装上红色装载圈(看步骤三)。但 是，如果在重新移动负载物时能多加小心就不需要 这个步骤了。请不要用水平螺丝水平对准顶板。NOTE: Cables, hoses, etc. connected to the payload can affect the horizontal and vertical position. If possible make the following adjustments without attaching the cables.注意：电缆，软管等

10、等这些连接到负载物都会影响 到水平和垂直位置。所以尽可能不要加上电缆而操 作调试。Floating Isolator Vertically 垂直方向浮动隔振器The isolator comes from the factory adjusted to support the nominal weight, (i.e. 25 lb for the BT-25-4; 50 lb for the BT-50-4; etc.). Internal stops limit vertical motion. The isolator must bea floated ” between thestops

11、.该隔振器出自厂家，经过调试而支持标称重量(例 如 25 lb for the BT-25-4; 50 lb for the BT-50-4 等 等)。内部阻塞限制垂直移动。该隔振器必须在阻 塞之间浮动”。Check Vertical Position Indicator (E). The pin should be approximately centered on the horizon line. Turn Load Adjustment Crank (F) only clockwise when the pin is below the line, and only countercl

12、ockwise when it is above the line. If the payload weight varies from nominal weight by a few pounds/kilograms, it may take many turns (approximately 10 turns per payload pound/kilogram).检查垂直位置的指示器(E)。对接线应该接近水 平线上的中心位置。当对接线低于水平线时应顺时 针转动负载调试手柄(F),相反，当对接线高于 水平线时应逆时针转动负载调试手柄(F)。当负 载物的重量与标称重量不同时，比如说相差几磅或

13、 几千克，这时应转动很多圈(大概负载物每磅或者 每千克就要转动十圈)。NOTE: To avoid damage, never force the LoadAdjustment Crank. If pin cannot be easily centered on line, turn Vertical Stiffness Adjustment Screw slightly counterclockwise and readjust vertical position. Repeat as necessary. This is a very sensitive adjustment. Turn

14、the screw only a few degrees each time.注意：为了避免仪器损坏，请勿用大力摆动负载调试手 柄。如果对接线不能调试到中间位置，逆时针轻轻转动 垂直固定调试螺丝以及重新调试垂直位置。有必要的话反复操作几遍。这个调试按钮是十分敏感的装置。每次 只能转动螺丝几度，请勿用力过大。Floating Isolator Horizontally水平浮动隔振器Internal stops limit the horizontal motion. The isolatormust be “floated ” horizontally between the stops by

15、adjusting the leveling screws. Horizontal Position Indicator screws (D) should be approximately centered within holes.内部阻塞限制水平移动。通过调试水平螺丝使该隔 振器必须在阻塞之间水平 浮动每个水平位置指 示器螺丝(D)都应该接近位于每个孔洞的中央。Example: If screws are too far to the left of center, turn front left leveling screw counterclockwise (as viewed fr

16、om above) and front right leveling screw clockwise the same amount.例如：如果螺丝太偏离中央的左方，逆时针转动左 前方的水平螺丝(正上方方向为标准)以及同时顺 时针转动右前方的水平螺丝。IF HORIZONTAL POSITION INDICATOR SCREWS ARE NOT VISIBLE, check positioning by pushing the top plate gently front to back then side to side. If it does not oscillate freely an

17、d independently front to back and side to side, then adjust accordingly.如果水平位置的指示器螺丝是不可见的话，通过轻 轻推压顶板从前到后然后从一边到另一边的方式检 查位置。如果它不能随意和独立从前到后以及从一 边到另一边振动的话就作相应的调试。HORIZONTAL NATURAL FREQUENCY 水平上固有频率.The horizontal natural frequency can only be changed by varying the payload weight. ? Hz is achieved when

18、 payload weight is near nominal (i.e. 25 lb for the BT-25-4). Increasing the weight lowers the frequency. Decreasing the weight raises the frequency. Ballast weights can be used for fine adjustments to frequency.仅仅当负载物的重量发生改变时，水车固有频率才 会发生改变。当负载物的重量接近标称重量时(比 如25 lb for the BT-25-4),那么频率就会达到1/2赫兹.重量越大

19、，频率越小。反之，重量越小，频率 越大。压载物的重量可以用来精细调试频率。Check the horizontal frequency by pushing horizontally on the edges of top plate to create small horizontal oscillations, then count cycles (one back and forth movement). For example, 3 cycles in 6 seconds is ? Hz. Depending on the damping, the isolator may only

20、cycle 2 or 3 times.通过在顶板的边缘上水平推压而产生小范围的水平 振动而检查水平方向的频率。之后用来计算周期(一前一后的移动)。例如，6秒内3圈是1/2赫 兹。该隔振器周期可能只有两次或者三次，具体情 况取决于阻尼。VERTICAL NATURAL FREQUENCY 垂直方向固有频率1/2 Hz- 3 cycles in 6 secs.Check the vertical frequency by pushing down vertically on top plate to create small vertical oscillations, then count cycles (one up and down movement). ? Hz is equal to one cycle in 2 seconds.通过在垂直方向推压顶板产工小幅度的垂直振动而检查 垂直方向的频率，然后计算周期(一上一下的移动)。 1/2赫兹等于两秒内一圈。The vertical natural frequency can be changed using the vertical stiffness adjustment screw (G), although this adjustment is seldom necessar
