Caibao dry pump has appeared very early, but there is no clear definition. As for replacing oil-sealed mechanical pumps, the general saying is: it can work in the pressure range from atmospheric pressure to 10-2Pa; in the pumping flow path (such as the pump chamber), no oil or liquid can be used. A pump whose air port is connected to the atmosphere and can continuously exhaust air into the atmosphere is called a dry vacuum pump (also known as an oil-free vacuum pump). There is no lubricating oil in the German Leybold thousand pump chamber. Four pairs of rotors with the same cross-section are fixed on two parallel axes in their respective pump chambers. They are connected and adjusted with a pair of time-limited gears to make them They do not touch each other and there is a certain gap. When the German LEYBOLD dry pump is working, the volume of the pump chamber continuously changes periodically, from large to small and from small to large. In this way, the opening and closing function of the gas channel is used to achieve the air extraction function, and a spliced complete set of structures is used, which is small and Impurities and dust can be discharged out of the pump together with the gas through the air channel. The maximum inlet pressure of the continuous operation of the pump is 5000Pa, and it can be discharged directly to the atmosphere. Classification:

There are many types of dry pumps available on the market today. In terms of their basic principles, there are only two categories, namely: ① Volumetric oil-free vacuum pumps, such as multi-stage Roots pumps, claw pumps, reciprocating piston pumps, screw pumps and scroll pumps, etc. The ultimate pressure of this type is generally 0.1~10Pa, and the pumping speed is 0.01~0.04m3?s.

②) Momentum transfer type oil-free vacuum pump, such as turbine oil-free pump. The exhaust side is connected to the atmosphere, and the compression ratio is high in the continuous flow state. It is a rough pump that can pump from atmospheric pressure to 1022Pa. Structurally, it adopts a composite structure of radial flow and circumferential flow pumps, with multi-stage air pumping in series. The ultimate pressure of this turbine pump is about 10-2Pa, and the pumping speed is 0.02~0.15m3?s. The Fengyin dry pump is also a momentum transfer type dry pump.

Compared with oil-sealed mechanical pumps, these dry pumps reach the same ultimate pressure, but their residual gas composition is completely different. The analysis results show that the residual gas of the oil-sealed pump, CnHm gas (hydrocarbon gas), is its main component, and The residual gas in dry pumps is a component of air. This confirms that the air pumping of the dry pump is no longer contaminated by oil. Some dry pumps still use lubricating oil in their structural design, such as the pump’s transmission gears and bearings. They also use synthetic oils, such as PFP oil and its greases, and certain measures are taken to prevent oil vapor from existing in the pump cavity. Strictly speaking, it is not a completely oil-free pump, but after analysis, the composition of this synthetic oil is minimal at the pump inlet and has no effect.
