Several concepts on vacuum pump

How to apply the vacuum pump in the processing of chemical production, you need to clearly define the following concepts: 1, the concept of "vacuum": "vacuum" refers to the gas state below a single atmospheric pressure in a given space, that is, The density of gas molecules in space is lower than the density of gas molecules in the region. The state of space without gas is called absolute vacuum. 2, vacuum pump: is used to produce, improve and maintain the vacuum device. 3, the amount of pumping: the vacuum pump in the work under pressure pumping unit of time the flow of gas. Unit: kg / h or m3 / h; 4, the ultimate pressure (vacuum): vacuum pump in the case of zero absolute pressure can be achieved. Unit: Pa, KPa, MPa or mmhg (the ultimate pressure minus the local atmospheric pressure is the ultimate vacuum); 5, the working pressure (vacuum): jet pump rated suction absolute pressure. Unit: Pa, KPa, MPa or mmhg (working pressure minus the local atmospheric pressure for the work of vacuum); 6, working steam pressure: steam jet vacuum pump working steam pressure. Unit: MPa or kgf / cm2; 7, working steam consumption: steam jet vacuum pump unit steam consumption. Unit: kg / h; 8, cooling water temperature: water jet pump circulating water temperature or steam jet vacuum pump condenser circulating water temperature. Unit: OC; 9, the amount of cooling water circulation: per unit time through the water jet or steam jet pump condenser circulating water flow. Unit: kg / h;

LED Ceiling Light
