Working safely with compressed air  tank

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.
Maintenance compressed air system

Maintenance compressed air system

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.

Guide of air filter maintenance

Compressed air system in factory plays an important role. In order to ensure the stable operation during the manufacturing process, the regulary maintenance is nescessary . However, there are many different problems in fact such as: Air compressors, dusty air dryers, high engine room temperatures, unsecured wind convection ... lead to reduce using time of compressor accessories (air filter, oil filter, oil separator ...). On the other hand, the recommended maintenance in some factories is not seriously followed and there are deviations. To extend the life of the machine as well as compressor components and ensure operator safety Air compressors are very important to maintain regularly and technically correct.Air compressors, dusty air dryers, high engine room temperatures, unsecured wind convection ... lead to reduced use time of compressor accessories (air filter, loc oil, oil separator ...). On the other hand, the maintenance (maintenance) recommended by the manufacturer in some factories is not guaranteed and there are deviated. To lengthen longevity of mạchine as well as compressor components and ensure operator safety , air compressors are very important to maintain regularly and technically .

Swan TS-V air compressor

Swan TS-V airr compressor series is a series of machines using inverter to reduce power consumption and have outstanding features of the Swan TS series. Based on operating phenomena to optimize operation, ensure maximum air volume and minimum power consumption, average electricity savings at: 15% - 30%. Protection and advanced control system improved reliability of safe and enhanced operating performance; Air compressor starts at zero speed, extending the machine's durability.

 Hitachi air compressor repair
 

Symptoms

Causes 

 Remedies 

Oil flows from upper air filter and coagulates

 Unload or  load in short time 

-Repair intake valve
- Check the closing time of relay and other wires.

Minimum pressure valve is leaked 

Repair and replace if nescessary 

 Air in contactor is insufficient 

Check the electromechanical shut-off valve
= Frequently switch  between load and unload

    

The leaked pipeThe leaked pipe   

 Check the possibly leaked  point

pressure parameters are set too low    

 Reset parameters

Unbalanced air consumption Increase container capacity and add pressure valve if needed

    Unbalanced air consumption

Increase container capacity and add pressure valve if needed

The  overloaded engine
-Signal: The  thermister is switched and the   motor
exceeds the norm
Consequences: fire engine, fire switch in electric cabinet. In many case,thermister has not yet affected but the engine has been burnt.

 

- Defective voltage and phase loss (with a machine without phase protection) - Failure of main motor. Motor bearings run out of grease, jammed gear, transmission part ... increasing  load - Air end is stuck, mechanical breakage/clogging of mechanical structure, axis misalignment, oil seal. This is the most common case
-Slow oil filter and oil separator

- High compressed air pressure leads to overload.

 

.

You only need to measure the voltage at unload and load or the machine with the same current in the same workshop to check and fix.  
-This error should remove the belt and check by hand whether the air end or engine is stuck before taking other measures.

- The oil separator is clogged or replaced if necessary
- Checking the presure control settings again. Another reason is that the pressure relief valve set the compressed air pressure higher than the designed pressure of the machine.
Reverse phase In the repairing process of electrical systems, it is possible to reverse the phase or when using backup generators in air compressors with anti-phase devices integrated in the control panel or using digital relays. Reversing 2 of the 3 power supply phases for the air compressor

Phase loss

Because of the electrical system, the breakdown of the wire....

Checking  the power system  can clearly find out
