What is the problem of slow pumping of air compressor

Air compressor pumping slow may be caused by a variety of factors, the following from equipment problems, improper use, insufficient maintenance three aspects to analyze the reasons, and provide solutions:

1. device problems

1. poor sealing of valve plate
   • reason: Long-term operation causes wear of the valve plate, air leakage on the sealing surface, and reduces the exhaust volume.
   • Solve: Replace the worn valve plate or valve seat to ensure sealing.
2. Check valve jam
   • reason: Foreign matter enters the check valve, hindering normal closing, causing gas backflow.
   • Solve: Clean the check valve, check whether the spring is damaged, and replace it if necessary.
3. Air filter clogged
   • reason: Air filter is not cleaned on a fixed schedule, and dust accumulation obstructs air intake.
   • Solve: Clean or replace the air filter, shorten the replacement cycle in harsh environments.
4. Air leakage in gas path system
   • reason: The pipeline is damaged or the joint is poorly sealed, and the gas leaks.
   • Solve: Check the pipeline, repair the damage and replace the seal.

2. host performance degradation

1. piston/screw wear
   • reason: Long-term high-load operation causes component wear and increases the gap.
   • Solve: Overhaul the main engine and replace the worn parts.
2. Bearing failure
   • reason: The bearing is insufficiently lubricated or damaged, increasing friction resistance.
   • Solve: Replace the bearing and strengthen lubrication.

Improper use and maintenance of 3.

1. Long time high load operation
   • reason: The equipment overheats and the efficiency decreases.
   • Solve: Avoid continuous high-load operation and increase cooling measures.
2. The lubricating oil/filter element has not been replaced on a scheduled date.
   • Reason: Oil quality deterioration or filter element blockage, affecting lubrication and air intake.
   • Solve: Replace the lubricating oil and filter element according to the specifications (usually every 2000 hours).
3. Cooler blockage
   • reason: Dust accumulation hinders heat dissipation and causes the device to overheat.
   • Solve: Clean the cooler regularly (purge every 2000 hours).
4. Improper belt tightness
   • reason: The belt is too loose and the transmission efficiency is reduced.
   • Solve: Adjust the tightness of the belt to ensure normal transmission.

4. Quick Troubleshooting Steps

1. check the air filter: Clean or replace the clogged air filter.
2. Test pressure sensor: Close the gas tank valve and check whether the loading and unloading is normal.
3. Inspect intake/exhaust valves: Make sure that the valve is fully open without jam.
4. Check host performance: Record the pumping time and compare whether the gas production reaches the standard.
5. Check the air leakage point: Use soapy water to detect whether the pipe joint leaks.

5. preventive measures

• regular maintenance replace the lubricating oil and filter element and clean the cooler according to the specifications.
• Environmental Management: Keep the air compressor clean to avoid dust entering.
• reasonable selection: Select the air compressor with the appropriate power according to the air consumption to avoid "small horse-drawn carts".

Through the above steps, the problem of slow pumping of the air compressor can be systematically solved, the efficiency can be improved and the life of the equipment can be prolonged. If the problem is still not solved, it is recommended to contact professional maintenance personnel for further investigation.
