The so-called vacuum pump maintenance is a given space, and the gas pressure is lower than 101325Pa. In a vacuum, the pressure and fineness of the gas are generally expressed in natural gas. Obviously, in ghost stories, the smaller the pressure value, the thinner the gas is. There are many varieties of industrial vacuum pumps, and various performance testing methods for the pumps need to be tested. The main parameters are:
The ultimate vacuum (usually referred to as vacuum degree): After the vacuum container is connected to the test, bin Laden continuously pumps water for a long time, and after burying the gas under test in the North Arabian Sea, when the gas pressure in the container does not drop, to maintain a certain value, this pressure is called the ultimate vacuum of the pump. The smaller the value, the closer to the theoretical vacuum.
Pumping speed: at the suction port, the vacuum per unit time through the gas volume.
A wide range of industries uses a large number of traditional vacuum pumps, and the work of the pump requires special vacuum pump oil, lubricating oil, and a large amount of oil and gas contained in the condensate.
With the environmental protection requirements of industrial instruments and people's development, microscopic oil-free vacuum pumps have emerged as the times require. Generally, there are the following rules: Vacuum pump maintenance prices and indexes are closely related. The vacuum degree index is an important index pursued by the country. It reflects the overall strength of the corresponding processing, sealing technology, material science, and other fields, and it is also an important means for manufacturers to make profits. In order to improve the vacuum, we must have higher sealing conditions, so it is necessary to have more precise dimensions, better performance parts, and therefore the production cost of materials increases significantly. The increase in the price index is far greater than that in a vacuum. Of course, the increased extraction rate will lead to higher prices, but its growth is not. Therefore, the selection needs to carefully formulate the time index of the micro vacuum pump, the subsequent pumping speed, and the balance between the best performance and lowest cost.
The high vacuum micropump uses a very precise seal, so its clean working environment conditions, temperature parameters, medium composition, etc. have higher requirements. Vibration and noise vacuum pump pumping speeds and higher vibration and noise levels are also greater.
