Swan HTW air compressor

SWAN HTW air compressor series are class II type, class II water cooling, compression efficiency enhancement, solid construction design, safety for use. There are l lubricating spray equipments preventing machines from erosion, minimizing oil loss, dehydration, overload, increasing long-term operation, chilling the cooling water, withstanding high ambient temperatures and reducing working temperature,and extending spanlife of machines.

Desiccants for Absorption air dryer

Activated alumina/Desiccant beads have a white, spherical, non-toxic, odorless, insoluble in water and alcohol. They are able to stand out thermal shock and abrasion with highly mechanical stability and strong absorption (impervious). The particle shape does not expand or crack after absorbing.

The maintenance compressed air systems are often specified in the system documentation, provided by the manufacturer. In this artical we would like to introduce some rules and maintenance regimes according to general regulation.

How to detect the failure of bearing?

Wednesday - 02/01/2019 04:24

Operating and using process of air compressors (in particular) and machinery equipment using bearings (in general). If a bearing is damaged during operation, it will lead to the entire machine or equipment being damaged. Once the bearings are damaged prematurely or cause unexpected incidents, it is important to be able to identify and predict the failures before processing, so that timely corrective actions can be taken.

How to detect the failure of bearing?

Normally, checking bearings can identify the cause of damage. Common causes of bearings failure are poor lubrication, incorrect fitting and removal, choosing incorrect bearings, uncarefully learning about the axis and the bearings. The cause can also be determined by considering the operation of the bearing before it fails, analyzing the lubrication and installation situation and carefully watching the damaged bearings.

In some cases the bearings are damaged quickly, however this early failure is different from others caused by scab. Bearing damage is divided and classified into two types of failure: premature failure of bearings and natural damage due to metal contact.

The symptoms, causes and remedies for bearing failure

Symptoms 

Cause 

Remedies 

Strange noise 

The loud noise of metals 

Abnormal load

The mounting, preset load mode, unbalanced bearing position.

Wrong installation

Machining accuracy and the concentricity between axis and the hole of coupling and improper assembly accuracy.
Insufficient or incorrect lubrication Add lubricants or choose other  lubricants

Rubbing of rotating parts

Change the ring design to make it tortuous

The regularly loud noise

Cranny, corrosion, scratch on the rolling groove

Replace or clean the bearings carefully, be sure a closed process and use clean lubricants

The dents

Replace the bearings carefully

The flaking on the rolling groove

Replace the bearings carefully

The irregularly loud noise

Excessive gap

Change mounting, gap, and preset load mode

Penetration of external element

Replace or clean the bearings carefully, be sure a closed bearing and use clean lubricants

Crack or rust on marbles

Replace new bearings

Abnomal temperature increase

Excessive lubrication Reduce the amount of lubricant and choose more solid one<
Insufficient or incorrect lubrication Add lubricants or choose the better lubricant

Abnomal load

The mounting, preset load mode, unbalanced bearing position.

Failure of installation 

Machining accuracy and the concentricity between axis and the hole of coupling and improper assembly accuracy.

Friction with the closed bearing or the surface is worn

Reasonable sealing, replacing new bearings, proper mounting modes, and   methods

Vibration

The dents

Replace new bearings

Scales 

Replace new bearings

Failed installation

Replace new bearings

Penetration of external element

Replace new bearings

Leakage or discoloration of lubricants

Excessive lubricant. Penetration of external elemeal or metal dust

Reduce the amount of lubricant and choose more solid one . Replace bearings or lubricants. Clean the bearing  and inner parts.
