3.INSPECTION AT DELIVERY &STORAGE 交付和存储时的检验
3.1 All actuators will be examined when delivered to ensure that they have not suffered any danage during transport .Inrorm the supplier innediay if there is any danage.
所有的气动头在交付时必须经过仔细检查以确保在运输过程中未受损坏。如果发现任何损坏,应产即告知供应商。
3.2 As standard ,actuators will leave the factory in closed position.
标准气动头在出厂时保持关闭位置
3.3 WARNING !!警告!!
Actuators will be stored under cover and protected from inclement weather conditions and dampness with air conducts properly covered.
为了防止恶劣天气的影响和受潮,每台气动头在存放时都用封闭式纸箱包装完好。
3.4 Actuators will not be unpacked untill their defintive installation ,except ror inspection purpsese.
气动头在要安装之前不得拆除包装,除非测试需要。
4.INSTALLATION 安装
4.1 The handling and transport of the actuators must be carried out with extreme precaution and using the necessary and adequate means depending on their size and weight in order to avoid risks to the operators handing them.
在搬运气动头时,根据气动头的大小和重量用合适的设备谨慎操作,以免发生危险。
WARNING!!警告!!
Check the state of the actuators in order to detect any damage produced during transport and /or handling.
在安装时先检查一下气动头的外观状况,防止在运送和操作过程中发生损坏。
4.2 Actuators should be installed in such a way that they are easy to acess in order to the periodic inspections and corresponding maintenance operations necessary to guarantee the performance qualities that they have been designed tor.
为了方便定期检测和相应的维护操作,气动头应安装在容易接触到的地方,保证设计要求的性能。
WARNING!!警告!!
Actuators must not support unexpected stress.lt is important to do the assemble with a correct alignment and parallelism to guarantee that is not submitted to unexpectde stress.
气动头安装时应保证——对应,以确保气动头不会受到因安装不当引起的意外压力的影响。
IMPORTANT!!重要
After the installation carry out afinal check of the actuator and make some opening and closing operatins to make sure that it works properly.
安装完毕后,在会后检查一下气动头,开启和关闭操作几次,以确保气动头正常运作。
WARNING!!警告!!
Actuators are lubricated before assembly therefore they will not need any extra grease Actuators are lubrcated before assembly therefore they will not need any extra grease after.
气动头在装备时已加过润滑油,因此以后不需要在额外加润滑油。
The use of dry and clean air increase the lifetime of the actuators ,as well as the lifetime of their accessories,solenoids and other pneumatic accessories.
利用干燥且干净的空气可以延长气动头合其他附件的使用寿命。
4.2.1RECOMMENDED MINIMUM AIR QUALITY推荐的空气质量
Oil content: Superior limit: 5mg/m3 Inrerior limit:1mg/m3
Water conten: Superior limit:3oc Inferior limit:-20oc
Maximum size of the dust particles:40microns
含油量:上限:5mg/m3 下限:1mg/m3
含水量:上限3oc下线:-20oc
粉尘颗粒的zui大尺寸:40微米
4.2.2 Actuators can be installed in line with the piping or at an angle of 900
气动头安装可以与管道平行,也可以与之成900
4.2.3 The normal performance of the actuators is to close clockwise and to open anticlockwise. However,this may be inverted under request.
通常情况下操作气动头的方法是顺时针关闭,逆时针开启,在有特定要求情况下可以逆转。
4.3 Make sure that the actuator and the valve are in the same position,open or closed.
确定气动头和阀门同时处于开启或关闭的位置。
4.4 When assembing the actuator on the valve,check the correct alignment of the set to ensure that the couping parts work perfectly aligned.
在阀门上装备气动头时,检查整套装置(阀门的气动头)是否正确对齐,以确保联接部分能衔接。
4.5 The coupling bolts,whether the actuator connects directly to the valve or uses a bracket,they must be tightened proportionally,distributing the stress,before tightening them compietey.
无论气动头是直接与阀门连接还是用支架与阀门连接,联接螺栓必须先按比例预紧,以分散压力,然后才能*拧紧。
IMPORTANT!!重要!!
It is advisable to operate the actuator twece before fully tightening the coupling bolts in order to ensure a good centring
在*拧紧连接螺栓前,对气动头进行试操作两次,以确保能正确合轴。
5. PREVENTIVE MAINTENANCE 预防性的维护
5.1 This basically consists in a periodic inspection to see the the correct functioning of the actuator
这部分基本上就是做周期性的检查,看看气动头是否运行正常。
5.2Actuators must be operated at least once every six months ,However,depending on the application of the actuator ,this may be done within shorter periods.
气动头至少每六个月运行1次,但是考虑到气动头的应用不同,可能在更短的周期内需要运行。
5.3 It is the end user’s responsibility to establish these operation plans depending on the working conditions.
zui终用户应根据各自的工作情况建立相应的操作步骤。
WARNING!警告!!
Never leave the actuators opened or closed during a long period of time.
5.4 It is recommended to replace O-rings,guides and washers when an in -depth revision of the installation is made.
如果气动头安装有较大的改变,建议更换密封圈,滑动异片和垫圈。
6.MAINTENANCE OPERATIONS 运行维护
6.1 PRECAUTIONS BEFORE DISASSEMBLY! 气动头拆卸前的防范工作
6.1.1 Disconnect the actuator and its accessories from the air and electrical network,
先将气动头合其他附件上的气源线和电源线拆下;
6.1.2 Disassembly the solenoid from the actuator.
再将电磁阀从气动头上拆下;
6.1.3 Disassembly the actuator from the valve and/or from its
