Liling dry titanium ore machine
2) why don't engineering companies build their own expressways to collect tolls
3) why don't high-speed rail companies carry passengers themselves
in a complete instrial chain, equipment manufacturers, proct procers, channel operators, retail cashers and so on constitute the instrial chain. Everyone has different division of labor. In these different division of labor, they jointly obtain profits in the instrial chain according to their contributions. This is a complete instrial chain.
I still remember that at this year's TGS conference, "Dyson ball project" spent 10 minutes to let its name reside in some foreign science fiction and simulation sandbox player communities
Due to the limited experience time, I can't bring you the complete experience of Dyson ball project, but one thing to share is that the current game scale is just the beginninga few months ago, the author sneaked into the test group of Dyson ball project, which includes only five developers of pomelo cat studio, as well as the publisher gamragame, and a group of test players who analyze many details of the game every day and suggest tuning
at present, the trial version that you see is graally polished out after several months and hundreds of QQ discussions every day. Sometimes I wonder if the sealed test players will be too "harsh" to argue about the sorting cycle (between milliseconds) of a sorter
however, when the base has begun to take shape, it is found that these details will indirectly affect the rationality of the logarithm and the accumulation of the whole logistics transportation network
when a large number of players swarm into the game, these problems will be exposed. Tuning is the most important part of a sandbox game. The potential of project Dyson's ball is enough for the sealed test players to take it seriously. It's a good thing that they have been involved in it for a long time, hoping to polish the game better
"from a part to the final grand proct", the charm of Dyson ball project lies in this

a dry air filter is a filter that separates impurities from the air through a dry filter element (such as a paper filter element)
there are two types of wet air filters: oil immersed and oil bath. The oil immersed filter is used to separate the impurities in the air through an oil immersed filter element.
mechanical methods include:
1. Variable volume vacuum pump
it is a vacuum pump that uses the periodic change of pump cavity volume to complete suction and exhaust in order to achieve the purpose of pumping. The gas is compressed before it is discharged from the pump chamber. This pump is divided into reciprocating and rotary type
reciprocating vacuum pump, rotary vane vacuum pump, fixed vane vacuum pump, slide valve vacuum pump, cycloid vacuum pump, liquid ring vacuum pump, dry vacuum pump and roots vacuum pump belong to this category
2. Momentum transfer pump
it relies on high-speed rotating blades or high-speed jet to transfer momentum to gas or gas molecules, so that the gas is continuously transferred from the inlet to the outlet of the pump
molecular vacuum pump, steam jet pump and diffusion pump belong to this category<
physical method:
gas trapping vacuum pump
is a kind of vacuum pump that makes gas molecules adsorbed or condensed on the inner surface of the pump, which can be divided into the following types
1. Adsorption pump is a kind of trapping vacuum pump, which depends on the physical adsorption of adsorbent with large surface area (such as porous material) to pump air. For example, molecular sieve adsorption pump
2. Getter pump is a kind of vacuum pump which uses getter to capture gas in chemical way. Getters are usually metals or alloys in the form of blocks or deposited fresh films. For example, titanium sublimation pump and zirconium aluminum suction pump belong to this type
3. Getter ion pump, which makes ionized gas adsorb on the surface of getter material through the action of electric field or electromagnetic field to achieve the purpose of pumping. It has the following two types
1) evaporative ion pump: a vacuum pump in which the ionized gas in the pump is adsorbed on the inspiratory material which is sublimated (or evaporated) in a discontinuous or continuous manner and covered on the inner wall of the pump to realize air extraction. For example, orbital ion pump (or ballistic titanium pump)
2) sputtered ion pump: a vacuum pump in which the ionized gas is adsorbed on the suction material continuously splashed by the cathode to achieve the purpose of pumping
4. Cryopump is a vacuum pump that uses cryogenic surface to capture gas.
