6. UNPACKING AND INSTALLATION 拆卸和安装
6.1 UNPACKING
拆箱
Once a suitable installation position has been identified, unpack the pump and prepare for installation. It is important
to inspect the pump to ensure that there has been no damage during transportation. The packaging material used
does not require any special disposal procedures. You should refer to you regional requirements.
当合适的安装位置确定后，解箱取泵，准备安装。重要的是要检查泵，确保了运输过程中没有损坏。使用的包装材料并
不需要任何特殊的处理程序。你应该指的是你的区域的要求。
6.2 PUMP INSTALLATION
安装泵
Allow sufficient space for install with 150mm clear space around the perimeter of the pump.
泵周围允许至少预留 150mm 的空间。
Mount the pump LocopumpSerie2 at “eye level” to avoid any risk of postural problems.
Do not install the pump in dangerous environments such as explosive/flammable areas or in areas subject to high
vibration.
Only use the fixing holes on the support bracket which are intended for n°2 holes for screws Ø10 mm (0,4 in.)(use a
flat washer with the screw ). For more details of the fixing holes please verify the dimensions shown on the drawing in
chapter 12.
为了正确地安装水泵，检查安装尺寸（见第 12 章的图）。
6.3 ELECTRICAL CONNECTIONS
电路接线
Ensure the electrical connection of the low level is connected before using the pump. See below drawing for
connection details. A label of this drawing is also on the pump’s reservoir.
使用泵前确保低水平电气连接连接。见下面连接的详细图纸。这方面的一个绘图标签在泵的油箱上。
Supply voltage 24 V max.
6.4 PUMP OUTLET CONNECTION 泵的出口连接
The hydraulic connection of the pump is on the front face of the pump. It is a standard 1/4” BSP (see drawing in
chapter 12).
泵的水力联系，是对泵的前面。这是一个标准的 1 / 4“BSP 的（见第 12 章图）。
6.5 AIR CONNECTION ON PUMP 空气连接上泵
Use a 1/8” BSP connection fitting. It also possible to use DropsA’s nut an cone fittings as the seating is already
available.
Remember to use a 3/2 valve that allows the air to vent to atmosphere and the internal spring within the pump to
reset.
使用一个 1 / 8“BSP 的连接配件。它还可能使用 DropsA的螺母作为一个座位锥配件已经存在。
记得用一个 3 / 2 阀，使空气泄至大气，并在泵的内部弹簧复位。
WARNING: The unit is only to be opened and repaired by specialist personnel.
警告：该单位只可以经授权的
Dropsa
人员打开和修复。

6.6 HOW TO ADJUST THE PUMP OUTPUT OR PRESSURE 如何调节泵的输出或压力
This can be done by: Regulating pressure: the output pressure has a 50:1 ratio with the inlet pressure. Therefore this
can be regulated depending on the requirements of the system. (see chapter 4 for min and max pressures).
Regulating pump: as standard the pump has a fixed output. For special requirements you can convert the pump by
installing the kit 3133390 – ordered separately to the pump – the kit is shown below.
To use this kit, mount the o-ring ( A ) then tighten the fitting ( B ) with a 27mm spanner. Loosen the counter nut (C)
with a 13 mm spanner to unblock the screw (D), use the appropriate screw driver to screw IN for less output or screw
OUT for more output. After adjustments have been made you must tighten the counter nut (C) to block any further
movements.
这可以这样做：调节压力：输出压力与进口压力 50:1 的比例。因此，这可以调节取决于该系统的要求。 （见最小和最
大压力第四章）。
调节泵：泵作为标准的固定输出。对于特殊要求，您可以通过安装转换套件 3133390 泵 - 单独订购的泵 - 试剂盒所示。
若要使用此工具包，安装的 O型圈（A），然后用 27mm 的扳手拧紧的装修（B）。松开了 13 毫米扳手的 counter nut
（C）以解除封锁的螺丝（D），使用适当的螺丝刀螺丝钉少产出或更多的输出渴望。经过调整，已使你必须 tighten 的
counter nut（C）阻止任何进一步的动作。
N.B.: After all connections have been made please ensure that they are safe and properly secured down.
注：所有连接后，已请确保它们是安全和适当地固定下来。

9. MAINTENANCE PROCEDURES 保养程序
Ensure the pump is positing so that it can be verified easily.
Ensure you have necessary personal protective equipment to avoid any contact with the grease.
确保泵并主张，以便它可以很容易得到验证。
确保您有必要的个人防护设备，以避免与油脂接触。
The pump undergoes severe factory testing therefore no maintenance is forecasted with the pump.
DropsA recommends the use of lubricants that are free of any impurities as well as a regular cleaning of the
pump’s components.
该泵经过测试，因此没有严重的工厂维护与泵预测。
DropsA 建议润滑油属于无任何杂质，以及作为泵的部件定期清洗使用。
The pump is dismantled as follows: 该泵拆除如下：
1. Before removing the reservoir is must be completely emptied of lubricant.
2. Disconnect the air inlet connection.
3. Disconnect all tubing on the pump.
4. Loosen the screws on the lid, remove the reservoir taking ABSOLUTE care of the spring inside the reservoir
( it may still be under tension – if so remove more lubricant.)
5. Remove the pump and any filters if fitted.
6. Unscrew the plug on the pneumatic pump body , be careful of the load on the internal spring. At this point you
can remove the internal components of the pump body.
1. 该泵体是消除之前必须完全清空的润滑剂。
2. 进气口的连接断开。
3. 断开所有的泵管。
4. 松开盖子上的螺丝，取出藏到内的泵体（它可能仍是紧张的 - 如果以消除更多的润滑油弹簧绝对照顾。）
5. 删除如装有任何泵和过滤器。
6. 在气动拧下泵体堵塞，无论是在内部弹簧加载小心。此时，您可以删除的泵体内部组件。
At this point all components are loose and allows the cleaning and verifying of each component possible.
All components must be clean with cleaning fluid and lubricated before re-assembly.
在这一点上的所有组成部分都宽松，允许每个组件的清洗和可能的核查。
所有组件必须干净，然后再清洗液和组装润滑。
Periodically it is necessary to check:

13. HANDLING AND TRANSPORT 装卸和运输
Prior to shipping, the equipment is carefully packed in cardboard package. During transportation and storage, always
maintain the pump the right way up as indicated on the box. On receipt check that package has not been damaged.
Then, store the machine in a dry location.
发货之前，该仪器仔细的包装用纸板包。在运输和储存，始终保持正确的方式了泵的包装盒上的说明。在收到检查计划
，也没有被损坏。然后，存放在干燥机的位置。
14. PRECAUTIONS FOR USE 使用注意事项
It is necessary to carefully read the warnings and risks associated with using a lubricant pump. The operator
must understand how it works and must clearly understand the dangers by studying the user manual.
要仔细阅读警告和使用润滑油泵相关的风险。经营者必须了解它是如何工作，必须清楚地理解学习用户手册中的危险。
Power supply
电源
Any type of intervention must not be carried out before unplugging the machine from power supply. Make sure that no
one can start it up again during the intervention.
All the installed electric and electronic equipment, reservoirs and basic components must be grounded.
任何类型的干预不能进行，然后再拔出从电源的机器。确保没有人可以启动它时再次干预。
所有已安装的电器和电子设备，水库和基本组成部分必须接地。
Flammability
易燃
The lubricant generally used in lubrication systems is not flammable. However, it is advised to avoid contact with
extremely hot substances or naked flames.
润滑油在润滑系统中使用的一般不易燃。然而，应避免与极热物质或明火接触。
Pressure
压力
Prior to any intervention, check the absence of residual pressure in any branch of the lubricant circuit as it may cause
oil sprays when disassembling components or fittings.
在此之前的任何干预，检查在任何电路分支的润滑油残余压力的情况下，因为它可能会导致油喷在拆卸部件或配件。
Noise
噪音
Pump produces noise, not more than 70 dB(A).
泵产生的噪音，不超过 70 分贝（A）。

15. OPERATIONAL HAZARDS 操作危险
The check on compliance with the essential safety requirements and with the stipulations indicated in the machine
directives are to be carried out by means of compiling the checklists already made available and contained in the
technical file.
关于与安全的基本要求，符合性检查，并规定在机器指令表示要进行核对表的编制方法进行，并已提供的技术文件中。
Two types of lists were used: 两种类型的列表使用：
• List of dangers (section from UNI EN ISO 14121-1 relating to UNI EN ISO 12100)
• Application of the essential safety requirements Machine Dir. - app. 1, part 1)
• 名单的危险（section from UNI EN ISO 14121-1 relating to UNI EN ISO 12100）
• 应用机署长的基本安全要求。 - 应用程序。 1，第一部分）
See below a list of dangers which have not been completely eliminated, but are considered acceptable:
• During assembly/maintenance it is possible that there may be an oil splash (consequently this operation must be
carried out using appropriate individual protective devices);
• contact with oil -> see instructions for using appropriate individual protective devices DPI;
• Loaded springs, in the pump cylinder and in the reservoir.
• Use of an inappropriate lubricant -> fluid characteristics indicated both on the pump and in the manual (if in doubt
consult our Technical Office);
• protection against direct and indirect contact must be provided by the user;
• The pump’s working logic requires it to operate at all times, so it is necessary to pay attention to the electric
connection. If there is no current the customer’s machine can only be restarted following a reset while the
lubrication pump can restart automatically.
• Do not use alcahol or spirits to clean any components.
看到下面有一个没有被完全淘汰的危险名单，但被认为是可以接受的：
在装配过程中•/维护它有可能有可能是油飞溅（因此这一行动必须进行适当的个人防护设备的使用）;
石油•联络 - >看到使用适当的个人防护设备新闻部的指示;
•弹簧加载，在泵筒和水库。
•使用了不适当的润滑剂 - >上注明的流体特性和泵两本手册（如有疑问咨询我们的技术办公室）;
对直接和间接接触•保护必须由用户提供;
•泵的工作逻辑，它要求工作在任何时候，所以要注意对电气连接。如果没有当前的客户机，只能重新启动后，复位而
润滑泵可自动重新启动。
•不要使用酒精清洁alcahol 或任何组件。
