机器的吊装: 概述：离心机安装时必须有技术员指导安装，且在操作离心机前必须经过双方技术员进行过机械和电气方面检查。 参考图纸：外形和基础安装图。 离心机出厂前完全配成配套设备后运输，安装离心机时无须任何局部拆卸。 危险：严禁用轴承座或离心机盖上的起吊螺栓来起吊离心机，因为这些起吊螺栓不能承受相应部件的重量，起吊离心机时必须通过离心机底座四角上吊环起吊。起吊设备前必须经过严格检查，并确认上述起吊用具完全可行，且对要求起吊的最大设备载荷有一较大安全系数，同时应考虑到提升时角棱处对链或钢丝绳应力集中因素。 吊链或钢丝绳必须固定好，以防起吊时部件或被吊设备倾斜危险，在吊起整台设备或大部件吊离基础机座或地面之前，应试吊看其是否平衡或挂到其他物体。 应确认正在起吊设备不碰到电线或起吊设备上方或起吊区附近的电缆，若起吊过程中有可能碰到电线或电缆，则必须切断它们的电源并将它们拆掉。 千万留心，不得将手和脚伸到起吊设备下面，或伸到起吊设备将要放置的地板上。 安装位置：安装离心机之前必须认真考虑好安装位置并优先考虑以下原则：离心机安装位置必须是便于操作和维修保养，连接管线设计必须确保介质流入离心机的流量满足要求而不致阻碍介质流动，进出离心机的管线的布置对离心机的性能有影响。 警告：根据离心机外形和基础安装图，留出拆卸进料管所需的上下、左右距离不得少于规定值，在离心机中心线的正上方应安装吊链起重机单轨用道，单轨道上的设计必须满足当将转动部件吊离机座后可以放置在一个干净的位置以便于维修。基础：出厂前离心机是动平衡的，但是由于所处理的工艺物料特性和其它原因使离心机在操作过程中会偶然产生不平衡载荷。因此，基础的强度必须足以承受上述载荷。 3.2 机座安装： 1、 基础位置见图“基础安装图” 2、 基础可以是混凝土结构或钢结构，用户可以选择最适于做基础的一种。 本机采用弹性基础，主机和传动部分（电机、差速器）等都安装在底架上，其下面用4 套减震器安装在基础上。 3、 校平机座 离心机的基础尺寸参见图，基础的水平底不大于1mm/m。 警告：进出离心机管道的接头必须采用挠性（弹性）接头 3.3 电气安装：安装并检测电气线路，马达转向。所有连接到离心机的导线管接头必须采用挠性接头，从而不对离心机的运动有影响。 3.4（安全）护罩：所有外露的转动部件配有安全护罩，在起动离心机前必须确认所有安全护罩都已就位且完好。 3.5皮带张紧力：装上皮带，给皮带垂直施加力，要求调整皮带张紧力，松紧程度以压下1.5～3.5厘米为准，不得太紧，并检查皮带有无损坏开裂。通常，在最初的72小时的运转过程后，应按以下步骤检查和重新调整皮带张紧力。 1、 停运离心机（应让所有转动部件都停下来） 2、 切断全部电气控制装置 3、 取下皮带护罩 4、 通过调整使张紧力的挠度达到规定值 5、 重新装上防护罩 警告：A、若张紧力过低，则皮带就会太松弛，即需增大两皮带轮间的中心距。 B、若张紧力过高，就需缩小两皮带轮间中间距。 危险：在着手任何维修保养等工作之前，必须停机并切断此离心机所有电源，否则将导致伤亡事故。 3.6机械及电气检查：出厂运输前所有离心机都经过试运行，为了运输、长期贮藏等需要对离心机采取了必要措施，起动离心机前必须进行如下检查。 附加检查： 1、 起动前，检查所有进料和出料管道的泄漏情况（密封性） 2、 检查传动皮带的张紧力是否合适 3、 检查并确认离心机及基础的连接螺栓已被紧固，且所有的护罩都装好就位并状态良好 4、 确认离心机各转动部件转动自如（给离心机各部位加油） 5、 检查所有联锁装置连接是否满足操作要求，若联锁装置不工作或失效或安装不合理将导致离心机被损坏 6、 检查离心机整个操作区域是否符合安全操作要求 7、 检查所有进料和液流管线并确认它们没有堵塞现象且管线系统中所有阀门都按要求打开 8、 起动离心机并确认转子转向与皮带防护罩指示的箭头转向一致，使离心机运行（温升）15分钟，并观察和记录空载时电流。 9、 建议在不给离心机喂料包括不进冲洗水的情况下，让离心机运行三小时，以便观察调整过的轴承和油温情况。 10、 记录全部温度，以便参考 |

太长了：（50-100 金币太少了。 给你改了改机器译的： Hoisting machine: Overview: the guidance of a technician is requested for centrifuge installation, and inspection from a technician for centrifuges in operation must be carried out both mechanical and electrical aspects. Reference drawings: shape and basic installation diagram. Centrifuge factory equipments completely dubbed in after the transportation and installation without any partial demolition during centrifuge. Dangerous: prohibit the use or the centrifuge bearing bolt for lifting the lid lifting centrifuges, since they can not afford the corresponding parts bolt lifting weight lifting centrifuge must be through the centrifuge base lifting rings on the corners. Lifting equipment must undergo rigorous pre-check and confirm the above-mentioned lifting appliances entirely feasible, and the best equipment for lifting loads require a larger safety factor, taking into account the edge at right angle to upgrade when the chain or wire rope stress concentration factor. Hanging chain or rope must be fixed well to prevent lifting or lift devices when the tilt is dangerous parts, in lifting the whole piece of equipment or large parts hanging from the base plane seat or on the ground before the examination to see whether the balance between hanging and other hanging objects. Should be recognized is lifting equipment that does not hit a wire or lifting equipment or lifting near the top of the cable, if the lifting may be encountered in the process of wire or cable, you must unplug them removed. Do pay attention, may not be the hands and feet out into lifting equipment below, or probe the lifting equipment will be placed on the floor. Installation position: Before installing centrifuges must seriously consider the installation of a good location and give priority to the following principles: centrifuge installation location must be convenient to operate and maintenance, the connection pipe must be designed to ensure that the flow of media into the centrifuges meet the requirements without impeding medium flows, centrifuge out of the layout of the pipeline affect the performance of centrifuges. WARNING: According to the shape and basic installation of centrifuges map, leaving out the necessary demolition of feeding tubes from top to bottom, left and right distance not less than the specified value, in the centrifuge should be installed above the center line of the hanging chain, monorail cranes, with the Road, single-track The design must meet When the rotating machine parts hanging from the seat post can be placed in a clean place to facilitate maintenance. Foundations: Centrifuge is a dynamic balance before leaving the factory, but because of the handling characteristics of craft materials and other reasons to make the process of centrifuges in operation would create an imbalance load occasionally. Therefore, the base must be sufficient strength to withstand the load. 3.2 Stand Installation: 1, basic position shown in Figure "basic to install map" 2, could be based on concrete structures or steel, the user can choose the most suitable for making a foundation. The machine uses elastic foundation, host and transmission parts (motors, differential), are installed on the bottom shelf, the following set of shock absorbers with 4 installed on the foundation. 3, Leveler Block the basis of size centrifuge see map, based on the level at the end of not more than 1mm / m. Warning: out of centrifuge pipe joints must be flexible (elastic) connector 3.3 Electrical Installation: Install and test electrical circuits, motors turn. All the wires connected to the centrifuge tube connector must be flexible joint, which does not affect the movement of centrifuge. 3.4 (security) guards: All exposed rotating parts with a security guard, in the centrifuge before starting make sure that all safety guards are in place and intact. 3.5 Belt Tension Force: attached belt, belt perpendicular to the applied force, for adjustment of belt tension force, tightness level to 1.5 to 3.5 centimeters depressed subject may not be too tight, and check the belt for damage cracking. Typically, the initial 72-hour operation process should follow the following steps to check and re-adjust the belt tension force. 1, outage centrifuge (due to all rotating parts are stopped) 2, cutting off all the electrical control device 3, remove the belt guard 4, by adjusting the tension force to achieve the required value of the deflection 5, re-fitted with protective cover Warning: A, if the tension force is too low, then the belt will be too loose, that is required to increase the center distance between the two pulleys. B, if the tension force is too high, would need to narrow the distance between the two pulleys. Dangerous: In the start before any maintenance work, you must shut down and cut off all power to the centrifuge, or will lead to casualties. 3.6 Mechanical and electrical inspection: All centrifuges are factory pre-shipment go through a trial run, in order to transport, long-term storage such as the need for centrifuges to take the necessary measures to start implementing the following checks before centrifuge. Additional check: 1, starting, check that all feed and discharge pipelines leakage (seal) 2, check the drive belt tensioning force is appropriate 3, check and confirm the basis of centrifuges and the connecting bolts have been fastened, and all of the shields are installed in place and in good condition good 4, confirm the rotating centrifuge components rotate freely (to refuel all parts of centrifuges) 5, check all interlock device connection is to meet the operational requirements, if the interlocking device does not work or failure or the installation will result in an unreasonable centrifuge is damaged 6, check whether the centrifuge operation region as a whole meet the safety performance requirements 7, check all materials and flow into the pipeline and make sure they do not have to plug the phenomenon and the pipeline system, all valves are required to open 8, start and confirm the centrifuge rotor steering and belt shield the arrow turned to the same direction, so that centrifuge run (temperature) 15 minutes, and observe and record no-load current. 9, it is recommended not to include the centrifuge feed into the washing water is not the case, let centrifuge run for three hours to observe the adjusted bearings and oil temperature conditions. 10, record all the temperature, for ease of reference. |
