Finding the cause of air compressor error - Part 1

Wednesday - 02/01/2019 04:30

During repairing and maintaining process of  air compressors for customers, we’re asked  many questions such as: Why does the machine run without pressure ?, Why does the discharged air  contain a high oil level ?. .. What causes the phenomena: The machine cannot start ?, The current is too high, the pressure increases too high, the air compressor does not stop? ... To solve those questions, we would like to give some following  basic reasons:

Replace suction filter element.

1. The warning light can not start

- Reasons
+ The fuse is broken
+The protection of  themal relay  is overloaded
+ The connecting wire is broken or loose
+ Grid voltage is too low
+ Broken motor 

+ Compressor oil incident

+ Failure of phase protection
+ Wrong phase  or lack of phase
+ The main structure does not work. Turn the main mechanism by hand to see if it turns or not.

 2. The high current, the compressor immediately stops

- Reasons :
+ Voltage is too low
+ High air discharge pressure

+ The electric contactor is not well working

+ Unsuitable lubricant parameters
+ Loose belt
+ Clogged oil filter

3. Operating current is lower than normal:

-Reasons :
+ High air consumption
+ the inlet of  air filter is clogged
+ Air valve is not well-operated
+ Adjusting the throtte valve with unsuitable level
+ Set unsatisfactory pressure

4. High temperature of discharged air,  air compressor emergency stops

- Reasons :
+ The insufficient amount of lubricating oil
+ The insufficient amount of cooling water
+ High the coolant temperature
+ Ambient temperature is too high> 40 degrees
+  The oil cooler is clogged
+ The parameters of compressor oil are not suitable
+ Breakdown of thermostatic valve (3-way valve)
+ The radiator frame is dirty, the heat dissipation is poor
+  The oil filter is clogged
+ Trouble of cooling fan
+ Thermal sensor is damaged
5. In the discharged air containing a high oil level, quickly replace the oil, when the engine stops, air filter is smokey.
 -Reasons :
+ The high lubricating oil level
+  Oil returning pipe is clogged
+ Low air discharge pressure
+ Oil filter is broken
+ Minimum pressure valve is broken.

6. The machine runs without pressure.

-Reasons :
+ Failure of pressure valve
+ Failed  3- way electromagnetic valve
+ Electromagnetic valve works incorrectly
+ The smallest pressure valve works wrong
+ The leakage of pipes
 +Failed control panel

7. Pressure valve does not work or continuously increases  relief  valve.

+ Pressure valve is broken
+ Air inlet valve works incorrectly

+ Problem of discharge electromagnetic  valve or clogged pipe

+  Air regulation is broken
