why the vacuum pump can not reach the maximum pressure?

Possible reason：

 

 

1.  The vacuum pump may be too small for the specific machine it's being used for. It's important to ensure that the pump is appropriately sized to handle the machine's needs.

2.  Using the incorrect measuring technique or gauge can also lead to issues with your vacuum pump's performance. Make sure you're using the right tool for the job.

3.  A low oil level can negatively impact your vacuum pump's performance. Check the oil level and add more if necessary.

4.  If there's a leak somewhere in your vacuum system, your pump won't be able to function as expected. Check for leaks and fix any that you find.

5.  If the exhaust valve on your vacuum pump is malfunctioning, it can cause issues with pressure regulation. Consider having it repaired or replaced.

6. Over time, the lubricate seal oil channel inside your vacuum pump can become blocked. Regular maintenance, including lubrication, can prevent this from happening.

7. The type and quality of oil being used in your vacuum pump can also impact its performance. Ensure the oil you're using is appropriate and change it regularly to prevent deterioration.

Remember, regular maintenance and proper use can help prevent issues with your vacuum pump. Keep an eye on your system and address any problems promptly to ensure proper operation and a longer lifespan for your equipment.

Solution：

 

1. Replace the pump

    

2. Use the correct measuring technique and gauge,measure the pressure directly at pump's intake port.

    

3. Adding Oil based on two-thirds rule(oil mirror)

    

4. Check the leakage(sealing element)

    

5. Repair the valve

    

6. Clean oil channel

    

7. Change the oil(Pump Oil only)
