The vacuum pump has a slow pumping speed and a poor vacuum degree

<
1. There is leakage in the system or connecting pipelines. (Leak detection and drainage)</p><p>
2. The filter screen in the intake pipe is blocked, the oil quantity is insufficient, and the oil is contaminated. (Unplug the rubber hose, remove the filter, clean it thoroughly; add new oil or change oil)</p><p>
3. The exhaust valve is damaged or jumps out of the pump chamber. (Replace the exhaust valve plate or return it to its original position)</p><p>
4. The O-ring seal of the intake pipe is damaged. (Replacement)</p><p>
5. Oil circuit blockage.
6. The pump oil temperature is too high. (Check if the oil circuit is blocked, improve ventilation, and reduce the temperature of the extracted gas)</p><p>
7. Wear of the rotary plate and breakage of the rotary plate spring. (Replacement of parts)</p><p>
8. The extracted box is too large. (Choose a vacuum pump that matches its body)</p><p></p>
