Why can't the vacuum pump reach the ultimate vacuum degree and how to solve it?

• Vacuum pump air inlet pipe and connections are leaking ----- Find out the cause of the leak and replace the leaking parts

• The vacuum pump oil is contaminated----replace with new vacuum pump oil

• The temperature of the extracted gas is too high ---- Install a cooling device on the air intake pipe to reduce the air intake temperature

• Insufficient oil or poor use of vacuum pump oil ---- Add vacuum pump oil to two-thirds of the oil level glass and replace with good quality vacuum pump oil

• Vacuum pump oil temperature is too low ---- In the cold season, the indoor temperature is too low, which affects the vacuum pump oil temperature. The pump can not work normally until it has been running for half an hour.

• The exhaust valve plate of the vacuum pump is damaged and leaking ---- Replace the exhaust valve plate of the vacuum pump with a new one

• The O-ring at the connection point of the vacuum pump air inlet pipe is damaged ---- Replace with a new O-ring

• The pumped gas contains condensable steam ---- add a gas ballast device or install a steam capture device

• Vacuum pump rotor is damaged ---- Due to long use time, parts are worn, which affects normal operation and vacuum degree, and must be repaired and replaced.

•  It is wrong to choose a vacuum gauge - a compression vacuum gauge should be selected according to the standard based on the measured partial pressure, or the full pressure measured by an electric vacuum gauge should be used as a reference
