Nanguang vacuum

1) the limits of vacuum pump pressure

The limit of the pump pressure unit is refers to the Pa, at the pump with standard test cover and the prescribed conditions, not into gas in work normal work, the trend of the lowest pressure stable.

2) the vacuum pump suction rate

Lashing velocity of pump unit is m3 / s or l/s, it is to point to a standard test pump cover, and the prescribed conditions work, from cover flow of gas flow test with the specified position in test cover measurement of pressure than the balance. "The pumping speed pump.

3) the vacuum extraction flow

The vacuum extraction flow unit is Pa m3 / s or Pa l/s. Refers to the gas pump inlet flow.

4) vacuum pump start-up pressure

The vacuum pump for Pa, starting pressure units it refers to the pump start-up and have no damage discharg gas pressure of the role.

5) pump pressure level before

The vacuum pump pressure level before unit is Pa, it is to show the exhaust pressure below an atmosphere of the export of vacuum pump pressure.

6) the maximum level before the vacuum pump pressure

Vacuum pump mouth before the biggest level pressure unit is, it is to point to exceed Pa can make to the damage of the pump pressure level before.

7) the biggest work pressure vacuum pump

The maximum pressure vacuum pump unit is Pa, it is to show the entrance of the largest corresponding extraction flow pressure. In this pressure pump can work, and not for progression or damage.

8) compression ratio

Compression is refers to the pump to a given the export of gas pressure and the ratio of the entrance pressure.

9) HeShi coefficient

Pump suction channel area and its actual pumping speed according to the theory of computation molecular diarrhea flow of pumping speed than.

10) pumping speed coefficient

The actual pumping speed pump with the pump according to the entrance of the calculation molecular diarrhea flow theory of pumping speed than.

11) returned to flow rate

The reflux pump unit rate is g/cm2. S. It is to point to pump according to the regulations, through the work condition of the pump unit area of the pump suction flow quality flow rate.

12) YunXuLiang water vapor

Steam YunXuLiang unit is kg/h, it is to point to pump in normal conditions, and the gas pump for work in the town of water vapor quality in a flow.

13) maximum allowable water vapor pressure entrance

The maximum permissible water vapor pressure unit is Pa entrance. It is to point to in normal conditions, and the gas pump in the town by the continuous can smoke in addition to water vapor pressure to the top of the entrance.
