ALFA-LAVAL型S系列分油机的几点管理要点
ALFA-LAVAL型S系列分油机的几点管理要点第一篇：ALFA-LAVAL型S系列分油机的几点管理要点ALFA－LAVAL型S系列分油机的几点管理要点ALFA－LAVAL公司在2000年以后相继开发了S系列的离心式分油机，这种分油机改变了传统的齿轮传动机构，以皮带带动分离筒高速运转从而达到分离水和杂质的目的。
我公司最近几年在一些新接船中采用了这种新型的分油机。
在实际船舶的使用维护和管理中发现立轴和皮带轮端的轴承经常会损坏，严重的甚至导致了立轴的弯曲等，检查审视各轮的备件消耗中也发现立轴和皮带端的轴承备件使用较多。
笔者把在船上实际中作用中的一些疑问和想法，与ALFA－LAVAL公司管理人员进行了一些沟通和交流。
目前，ALFA－LAVAL公司提示：在今后，供船上的皮带轮端轴承座会使用改进型的轴承座，船上在以后接收到新备件时可进行对比。
同时他们也提出了一些实际使用和管理该种类型分油机的注意事项。
在这里写出供大家参考。
一、立轴轴承的预润滑每次在更换立轴轴承时要在两个轴承中倒入一些滑油作为预润滑（英文原文为to pour some frame oil in both bearings at the sssembly as prelubrication）,原因是分油机启动运转后那些带油气的空气需花一些时间，才能到达轴承处开始对轴承进行润滑。
也就是说在更换轴承后如果没有预先加入一些滑油，那么在分油机开始运转的阶段轴承是处于缺油的状态。
因为船上配备分油机都有好几台，正常运行只是其中的一半左右，在管理中要注意，为了防止立轴轴承因为缺油导致损坏，一台分油机如果停止30日以上，则分离筒必须解体检查和清洁，要检查有无脏东西和异物灰尘等进入轴承座中和检查油泵进油孔是否清洁，尤其重要的是启动前要对立轴中间轴承轴承盖和油扇进行拆检，同时要滴入5滴滑油对它们进行润滑，所以我们建议船上人员要及时更换全胜各台分油机，停用时间不要超过一个月，如果超过了一个月，就要按照上述要求对立轴的轴承进行预润滑处理。

or feed concentration. The centrifuge can thus be operated closer to the clogging point without increasing the risk of clog-ging. The light and heavy phase are both discharged under pressure which prevents foaming and simplifies installation by eliminating pump systems and improves the hygiene. Solids pockets in the bowl guide the solids to the concentrate tubes, preventing accumulation of firmly packed solids and making separation and Cleaning In Place (CIP) easier and more effec-tive. Automated CIP at full speed.Frame hood and solids receptacle are jacketed for circulation of cooling water, which also reduce the noise level. Frame hood is fitted with a spray nozzle for washing the outside of the bowl. A rotating liquid seal below the bowl seals off the bowl casing from the drive system.MBUX 420Standard designThe MBUX 420 has all liquid-wetted parts in high-grade stain-less steel and rubber sealings food approved EPDM or nitrile rubber. Connections for inlet, centrifugate and concentrate are hygienic screw couplings. The separator is equipped with speed and vibration sensors. The anchoring feet are equipped with vibration dampers. The MBUX 420 is driven via a belt by a flange-mounted controlled torque motor. The separator is delivered with the motor pre-mounted at the factory so there is no need for alignment on site.Operating principlesSeparation takes place in the disc type bowl which is equipped with concentrate tubes and vortex nozzles. The heavy solids phase is moved outwards by the centrifugal force in to the solids pockets at the bowl periphery and from there through concentrate tubes (1) and internal vortex noz-zles (2) into the paring tube chamber, where the concentrate is skimmed off by the paring tube (3) and discharged under pressure. The clarified liquid phase is displaced towards to the centre through the disc stack (4). This phase is then dis-charged under pressure by means of a built in paring disc (5). The bowl can be opened intermittently during production and/or the cleaning cycle for ejections of solids while the machine continues to run at full speed. The hydraulic (6) controlled valve slide (7) under the bowl bottom opens the discharge valves (8) momentarily, permitting the ejections of solids.PPM00125EN 0511How to contact Alfa LavalUp-to-date Alfa Laval contact details for all countries are always available on our website at Alfa Laval reserves the right to change specifications without prior notification.18Typical bowl drawing for a vortex nozzle centrifuge.
