What causes vacuum pump failure

In the working process of a vacuum pump, there are some failures:

  1. Insufficient vacuum: it can not reach the ultimate vacuum of a vacuum pump.
  2. The oil leakage of a vacuum pump, which is one of most common questions of a vacuum pump.
  3. The abrasion of a vacuum pump’s bearing, which is a common question of a vacuum pump.
  4. Corrosion, which includes overall corrosion and partial corrosion.

What are the troubleshooting of vacuum pump

These are the troubleshooting solutions of a vacuum pump aiming at the failures above:

  1. Check if there is air leakage and drain compressible steam from non-pump oil contamination. Replace rotor and spring with new, and clean rotor and pump cavity. Check the exhaust valve and change it if necessary.
  2. Replace worn-out oil pumps, shaft seals, gaskets, and vacuum pump accessories such as felt pads that have been filled with pump oil, and keep the oil tank clean.
  3. Replacethe original imported vacuum pump accessories, which can fundamentally solve the problem. Make sure to use original parts or imported vacuum pump parts of good quality for replacement.
  4. Make sure to use high polymer composite material on the surface of the vacuum pump, which has very good chemical resistance, excellent mechanical properties and adhesive properties.
