Working safely with compressed air tank

Safely using of compressed air tank is a very important issue, compressed air tank before being used must be tested by KTAT, registered for use following regulations. Users must hand over the managing responsibility the compressed air tank to the equipment manager in writing. Operating of thetanks is only given to people from 18 years old or older, who are physically fit and well-trained. They must be assigned by the employer in writing.

Variable Frequency Driver (VFD) -reducing energy consumpsion system is produced with the required amount of air and compressor shutdown under no-load conditions. In order to minimize unnecessary energy loss through the inverter to adjust the number spin of compressor Energy consumption saving arises starting by reducing the starting current as the inverter is operated.

Common causes and troubles of vacuum pump

During operation as well as operation of operators '"Malfunction is unavoidable'" Some basic incidents such as: Do not reach vacuum level, pump overload ... With many years of experience, We have successfully repaired many vacuum pumps. The following are some of the reasons why the vacuum pump failures, and some common vulnerabilities with the hope that the operator can identify and take prevention.

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.
