AI880-1处理器模块
•称重传感器的基础必须尽可能稳定。坚固的结构降低测量辊和轴承装置的振动能量。
•最靠近称重传感器的表面以及影响配合的其他表面必须进行机械加工fl@t至0.05mm以内。
•称重传感器上方或下方不得有任何垫片，因为可能不利影响fl@tness相反，垫片可以放置在适配器板和基座或适配器板和轴承箱之间。
•固定称重传感器的螺钉必须用扭矩扳手拧紧。
•测量辊的轴承布置必须设计为允许轴向膨胀：随温度变化的辊。
•对辊施加任何驱动时，必须确保来自驱动的干扰力：保持在最小值。
•测量辊必须动态平衡
•称重传感器的安装表面必须位于同一高度，并与测量辊。
•在腐蚀性环境中，称重传感器之间可能发生电偶腐蚀，镀锌螺钉和转接板。这就需要使用不锈钢螺钉以及不锈钢或同等材料的转接板。参见图纸中的适配器板。
3.2开箱设备到达时，对照交付文件进行检查。通知ABB任何投诉，从而可以立即校正误差并避免延迟。
准备工作通过检查必要的文件和材料，及时准备安装
可用，如下所示：
•安装图纸和本手册。
•标准工具、扭矩扳手和仪器。
•防锈，如果对机加工表面进行额外保护。例如，选择TECTYL 511（Valvoline）或FERRYL（104）。
•称重传感器、转接板、轴承箱等。
•第20页表2所列用于固定称重传感器的螺钉，以及其他螺钉
用于轴承箱等。
3.4转接板
PFTL 101系列中所有称重传感器类型的适配器板必须经过加工，并具有fl@tness最大偏差为0.05 mm，要求的表面光洁度应为Ra 3.2。
对于PFTL 101A，转接板的厚度应至少为30 mm，对于PFTL101B35 mm，见图15。适配器板的安装和称重传感器的校准第21页信息
当安装PFTL 101AER和PFTL 101 BER时，必须使用奥氏体钢的适配器板，优选耐酸或不锈钢。
• The foundation for the load cell must be made as stable as possible. A sturdy construction
reduces the vibration energy of the measuring roll and bearing arrangement.
• The surfaces closest to the load cell, and other surfaces that affect the fit must be machined
fl@t to within 0.05 mm.
• There must not be any shims immediately above or below the load cell, as this may
adversely affect the fl@tness
Instead, shims may be placed between the adapter plate and
the foundation or between the adapter plate and the bearing housing.
• The screws that secure the load cell must be tightened with a torque wrench.
• The bearing arrangement for the measuring roll must be designed to allow axial expansion of
the roll with changes in temperature.
• Any drive to the roll must be applied in such a way that interfering forces from the drive are
kept to a minimum.
• The measuring roll must be dynamically balanced.
• The mounting surfaces of the load cells must be on the same height and parallel with the
measuring roll.
• In a corrosive environment, galvanic corrosion may occur between the load cell,
galvanized screws and adapter plates. This makes it necessary to use stainless steel screws
and adapter plates of stainless steel or equivalent. See adapter plates in A Drawings.
3.2 Unpacking
When the equipment arrives, check against the delivery document. Inform ABB of any complaint,
so that errors can be corrected immediately and delays avoided.
Preparations
Prepare the installation in good time by checking that the necessary documents and material are
available, as follows:
• Installation drawings and this manual.
• Standard tools, torque wrench and instruments.
• Rust protection, if additional protection is to be given to machined surfaces. Choose TECTYL 511 (Valvoline) or FERRYL (104), for example.
• Load cells, adapter plates, bearing housings, etc.
• Screws as listed in Table 2. page 20 to secure the load cell, and other screws
for bearing housing, etc.
3.4 Adapter Plates
The adapter plates for all load cell types in the PFTL 101 family must be machined and have a
fl@tness deviation of maximum 0.05 mm, required surface finish should be Ra 3,2.
For PFTL 101A the thickness of the adapter plates should be minimum 30 mm, and for PFTL 101B
35 mm, see Figure 15. Installation of Adapter Plates and Alignment of Load Cells page 21
Information
When installing PFTL 101AER and PFTL 101BER adapter plates of austenitic steel must be used,
preferably acid resistant or stainless steel.
