The working pressure range for vacuum pumps depends on the type of pump and its design. Here are the typical working pressure ranges for some common types of vacuum pumps: Rotary Vane Pump: These pumps typically have a working pressure range of 10^-3 to 10^-9 torr. However, their ultimate pressure is limited by the vapor [...]

Cleaning a liquid ring vacuum pump is an essential maintenance task that helps to ensure that the pump operates efficiently and prolongs its lifespan. Here are some general steps to follow: Shut off the pump and disconnect the power supply. Ensure that the pump has completely cooled down before proceeding. Remove the casing of the [...]

Here are some common technical terminology associated with vacuum pumps: Ultimate pressure: The lowest pressure a vacuum pump can achieve, typically measured in millitorr or Pa. Pumping speed: The rate at which a vacuum pump can remove gas molecules from a system, typically measured in liters per second or cubic feet per minute. Backing pump: [...]

Rotary vane vacuum pumps use oil as a lubricant to seal and cool the vanes as they rotate, and sometimes oil can be sprayed out of the pump during operation. Here are some steps you can take to check and deal with oil spray in a rotary vane vacuum pump: Check the oil level: Ensure [...]
