We describe the generalized numerical measure of the characteristics of an oil-sealed vacuum pump, which is some characteristic value of an oil-sealed vacuum pump that researchers want to know. Often when we are studying the current problems, we often care about the changes of a few variables and the interrelationships among them, one or some of them are independent variables and the other one is called the dependent variable. These are the relevant parameters of the oil-sealed vacuum pump, understand its parameters for understanding this product is very useful. Oil-sealed vacuum pump oil-sealed vacuum pump parameters: 1, the ultimate pressure of the oil-sealed vacuum pump: Pump's ultimate pressure unit is Pa, is the pump at the entrance with a standard test cover and the provisions of the working conditions, without the introduction of normal gas work Under the trend of the lowest pressure. 2, oil-sealed vacuum pump suction rate: pump pumping speed unit is m3 / s or l / s, is the pump equipped with a standard test cover, and work in accordance with the provisions of the conditions, the gas flow from the test cover flow and The ratio of the equilibrium pressure measured at the designated location of the test hood. . 3, oil-sealed vacuum pump exhaust volume: vacuum pumping unit is Pam3 / s or Pal / s. It refers to the pump inlet gas flow. 4, the start-up pressure of the oil-sealed vacuum pump: the starting pressure of the vacuum pump unit Pa, refers to the pump start without damage and the pressure of the role of suction. 5, the front-stage pressure of the oil-sealed vacuum pump: the pressure unit of the front stage of the vacuum pump is Pa, which means the outlet pressure of the vacuum pump with the discharge pressure lower than one atmospheric pressure. 6, the maximum pressure of the oil seal vacuum pump: the largest pressure unit before the vacuum pump mouth unit is Pa, refers to more than can make the pump damaged before the pressure. 7, the maximum working pressure of the oil-sealed vacuum pump: The maximum working pressure of the vacuum pump unit is Pa, referring to the maximum amount of suction inlet pressure. It has the characteristic that at this pressure, the pump can work continuously without deterioration or damage. 8, oil-sealed vacuum pump compression ratio: compression ratio refers to the pump for a given gas outlet pressure and inlet pressure ratio. 9, the Ho seal coefficient of the vacuum pump: the actual pumping speed on the pumping channel area and the ratio of theoretical pumping speed calculated by molecular effusion. 10, oil-sealed vacuum pump pumping coefficient: the actual pump pumping speed at the entrance to the pump by molecular diarrhea theoretical pumping speed ratio. With the further development of the vacuum pump, the development and application of the oil-sealed vacuum pump is also more extensive, and its role in the industry is more and more important. For the further study of its relevant parameters for the development of the industry is a very important issue.
