Analysis of common faults of air compressors

First, the main reason for the air compressor to burn tiles?

(1) The amount of oil in the oil pan (or crankcase) is insufficient, or the oil circuit is not smooth, resulting in poor lubrication;

(2) The oil pressure is too low, the normal oil pressure should be 0.15 0. 3MPa, when the oil pressure is lower than 0.08MPa, it should be
Stop immediately for inspection.
(3) The mating contact surface between the bearing bush and the bell neck does not meet the requirements, usually the contact area is not less than 75%, and the distribution of contact points
If the assembly gap between the uranium bush and the journal is too large or too small, the oil cannot form a fixed oil film during lubrication, and the

Poor lubrication.

(4) The ovality of the crankshaft journal exceeds the requirements, so that the oil cannot form a certain oil film during the lubrication process, resulting in poor lubrication.

(5) The back of the big end of the connecting rod is worn, causing the back of the bearing bush and the big end of the connecting rod to be unable to fit closely, causing the bearing bush of the connecting rod to burn.

(6) The quality of the bearing bush alloy is not good, and the alloy and the bottom tile cannot be completely and tightly fitted together.

(7) The center of each main bush is inconsistent, causing the crankshaft to run in the main bush, and some places are large and thin, resulting in dry friction and strict

When it is heavy, it will cause tile burning.
Second, the air compressor is not pumping?
Fault phenomenon: The air compressor discharges without pressure air.
cause of issue

1. The air compressor release valve is stuck. The valve plate is deformed or broken.
2. Excessive carbon deposits at the intake and exhaust ports.
   Troubleshooting and troubleshooting.
3. Check the relief valve components, clean and replace the failed parts.
4. Disassemble and inspect the cylinder head, check the valve plate, and replace the deformed and broken valve plate.
5. Disassemble and inspect the cylinder cover, and clean the valve seat plate and valve plate.
   What do these mean:
6. This means that, due to reflections, we cannot place a compressor in a room and then expect to have a
   under the same noise level.
7. We can’t just rely on two different units (with different speeds, different drives, different components and different enclosures)
   You can make a smart guess about the noise level. The only way to measure noise is to use a sound measurement device.
   Third, how do we overcome the apparent differences in noise levels?
8. By accurately measuring the noise level
9. By knowing how the noise level is constituted, the difference in frequency and harshness can be specified rationally.
10. Know that two units have the same noise level, but the damage to the ears of the unit noise with different frequency characteristics is the same, even if
    Of these – one does “sound” a bit lighter.
    Fourth, how can we further reduce noise?
11. Ensure that all joints in the machine body are safe, the forklift hole is closed, and the base of the machine set on the ground is solidly sealed.
12. Intake and exhaust are conveyed through pipes. .
13. Reduce reflection noise.
