Technology: Simple Sealing Solution for Pump Shafts

Simple Sealing Solution for Pump Shafts

Written by Thomas Yoon

In this issue, we will focus on a much simpler way of sealing a rotating shaft of a pump. It's by using gland packing. This method of sealing has been in use for a very long time, and is still being used today.

There are advantages and disadvantages in using them.

Perhaps repparttar first and foremost reason for replacing them with mechanical seals is because of repparttar 133420 fact that gland packing needs a small amount of leak for cooling purposes.

A person who installs a gland packing must ensure that repparttar 133421 latter does not grip repparttar 133422 shaft too tightly. A little dripping must be allowed for. Pumps that contain hazardous liquids should not use them at all.

Pumps that contain gland packing will usually be constructed with a small well and piping at repparttar 133423 gland to lead repparttar 133424 leak water away from repparttar 133425 pump so as to ensure that repparttar 133426 water will not damage repparttar 133427 bearings, housing or foundation. This can really mess up repparttar 133428 pump area if there is a choke at repparttar 133429 drain piping that prevents repparttar 133430 leaked water from flowing away.

The pump gland nuts may need to be tightened every now and then due to slight loosening after some time of operation. This is because repparttar 133431 nut cannot be tightened hard against repparttar 133432 soft packing.

Because repparttar 133433 packing gland rubs against repparttar 133434 shaft, it will tend to wear down repparttar 133435 shaft. For this reason, and especially for larger pumps using packing glands, there will usually be a shaft sleeve that can be slipped over repparttar 133436 shaft. The wear down will then occur only on repparttar 133437 shaft sleeve. This can be replaced instead of repparttar 133438 more expensive shaft.

Easy Way to Troubleshoot Pump Problems

Written by Thomas Yoon

In any problem analysis, we have to specify repparttar

problem, check whether there is any deviation from repparttar 133419

normal condition, identify repparttar 133420

possible causes, evaluate repparttar 133421

possible causes and then confirm repparttar 133422

true cause.

Pumps or other machinery will give tell tale signs when they are not working properly. An observant pump user will be able to avoid major breakdowns or damage if repparttar 133423 problem is corrected early.

In order to solve any pump problem, we need to notice repparttar 133424 symptoms carefully so as to determine repparttar 133425 most likely causes. Instruments like pressure gauges are very helpful and should be installed in repparttar 133426 pumping system.

Very often we do have to rely on our 5 senses to pinpoint repparttar 133427 exact symptom. Normally, pump problems can be classified into Suction Related, System Related, or Mechanical Related. It can also be a combination of these.

Most of repparttar 133428 system related problems occur because of design flaw. For example, repparttar 133429 designer may have chosen repparttar 133430 wrong pump whose characteristic does not match repparttar 133431 system requirement. Suction related problems are usually caused by air lock that are due to a variety of reasons...

The effects of mechanical related problems could manifest themselves as suction related problems - air leaks in repparttar 133432 system, worn out impellers, and mouth rings - but repparttar 133433 most common symptom is repparttar 133434 presence of vibration and abnormal noise in repparttar 133435 equipment.

DiagnoPump, pump troubleshooter has been created for pump users and sellers to help them find repparttar 133436 solution quickly. Arranged so that repparttar 133437 easiest (and often overlooked) causes are examined first, it could be a very useful tool.

If you are a beginner, you can start repparttar 133438 troubleshooting from repparttar 133439 very first steps. More experienced users may want to start from repparttar 133440 later stages in repparttar 133441 symptom list. The symptoms have been identified to make it easy to zero in on repparttar 133442 correct ones. The symptoms have been arranged as:
