Vacuum Pump Parameters- Specifications- Technical Data Sheet

  1. The ultimate pressure of the vacuum pump

The ultimate pressure is also called ultimate vacuum, and the unit is Pa. In the case of normal operation without introducing gas, the lowest pressure tends to be stable, that is, the inlet end of the vacuum pump passes through. The lowest stable pressure that can be achieved after full pumping.

 

  1. The pumping speed of the vacuum pump

The unit of pumping rate is m³/s or l/s, which refers to the ratio of the gas flow when the pump works according to the specified conditions. That is, it refers to the volume of gas that the vacuum pump can pump out per unit time, which is one of the important performance indicators of the vacuum pump, referred to as the pumping speed.

 

  1. The suction capacity of the vacuum pump

The pumping volume unit of the vacuum pump is Pa m³/s or Pa l/s. It’s the gas flow at the pump inlet. 

 

  1. The starting pressure of the vacuum pump

The starting pressure unit of the vacuum pump is Pa, which refers to the pressure when the pump starts without damage and has a suction effect. 

 

  1. Maximum working pressure of vacuum pump

The maximum working pressure unit of the vacuum pump is Pa, which refers to the inlet pressure corresponding to the maximum pumping volume. At this pressure, the pump can continue to operate without deterioration or damage. 

 

  1. Compression ratio

Compression ratio refers to the ratio of the outlet pressure to the inlet pressure of a pump for a given gas. 

 

  1. Allowable water vapor amount

The allowable water vapor unit is kg/h, which refers to the mass flow of water vapor that the gas ballast pump can pump out under normal environmental conditions. 

 

  1. Maximum allowable water vapor inlet pressure

The unit of maximum allowable water vapor inlet pressure is Pa. It refers to the highest inlet pressure of water vapor that can be pumped out by the gas ballast pump during continuous operation under normal environmental conditions.
