Rotary vane vacuum pump structure diagram of the principle of introduction

According to the relevant information, we know the definition of rotary vane pump eccentric pump installed within the rotor and the stator fixed surface tangent, two (or more) rotary vane Slide in the rotor slot (usually radial) and in contact with the inner wall of the stator, the pump chamber is divided into several variable volume of a rotating variable volume vacuum pump. Normally, the gap between the vane and the pump chamber is sealed with oil, so the vane vacuum pump is usually an oil-sealed mechanical vacuum pump. Next, Asia Fluid Network Xiaobian will bring you the introduction of rotary vane vacuum pump structure. Rotary vane vacuum pump schematic diagram of the principle Rotary vane vacuum pump structure of the structure Rotary vane vacuum pump structure can be drawn off the sealed container of dry gas, if accompanied by gas-town device, you can also extract a certain amount of condensable gas . However, it is not suitable for the extraction of gases that are highly oxygenated, corrosive to metals, react chemically to pump oils and contain particulate dust. Rotary vane vacuum pump vacuum technology is one of the most basic vacuum access equipment. Rotary vane pump for small and medium-sized pump. Rotary vane vacuum pump has a single-stage and two-stage. The so-called two-stage, is the structure of two single-stage pump in series. Generally made more double-stage, in order to obtain a higher degree of vacuum. The relationship between the pumping speed and the inlet pressure in the structure diagram of a rotary vane vacuum pump is specified as follows: Under the inlet pressure of 1333Pa, 1.33Pa and 1.33 × 10-1 (Pa), the pumping speed shall not be lower than the nominal pumping speed Of 95%, 50% and 20%. Rotary vane pump mainly by the pump body, rotor, rotary vane, end caps, springs and other components. A rotator is eccentrically mounted in the cavity of the rotary vane pump, the outer circumference of the rotor is tangent to the inner surface of the pump cavity (both have a small gap), and two rotary vanes with springs are arranged in the rotor slot. Rotation, by centrifugal force and the tension of the spring so that the top of the rotary vane and the inner wall of the pump chamber to maintain contact with the rotor rotation of the rotary vane slide along the wall. Rotary vane vacuum pump schematic diagram Rotary vane vacuum pump structure diagram We can see that the rotary vane pump rotor, the cavity and the two end caps surrounded by crescent-shaped space divided into A, B, C In three parts, when the rotor rotates in the direction of the arrow, the volume of the space A communicating with the suction port gradually increases and is in the process of inhalation. While the volume of the space C communicating with the exhaust port is gradually reduced and is in the process of exhausting. The volume of the central space B is also gradually reduced, is in the process of compression. Rotary vane vacuum pump structure due to the volume A is gradually increased (ie, expansion), the gas pressure decreases, the pressure at the entrance to the pump is greater than the pressure inside the space A, so the gas inhalation. When the space A and the suction port isolated, that is, to the space B position, the gas began to be compressed, the volume gradually reduced, and finally connected to the exhaust port. When the compressed gas exceeds the pressure of the exhaust gas, the exhaust valve is pushed by the compressed gas and the gas is discharged into the atmosphere through the oil layer in the fuel tank. By the continuous operation of the pump, to achieve the purpose of continuous extraction. If the discharge of gas through the airway and into another level (low vacuum level), from the low vacuum stage pumped away, and then by the low vacuum stage after the discharge to the atmosphere, the composition of the two-stage pump. At this time the total compression ratio is borne by two levels, thus increasing the ultimate vacuum. Above is the fluid network Xiaobian bring you rotary vane vacuum pump structure information. I hope for your understanding of the rotary vane vacuum pump structure diagram helpful. (Editor: Qian Wen)

Biomass material is a renewable resource, but different biomass forms are different. Therefore, it is necessary to make biomass pellets of uniform shape and size from biomass raw materials, so that biomass material can be better utilized. Biomass Pellet Burner is based on biomass pellets as fuel, which is different from general Biomass Burner. The biomass burner produced by our company adopts semi-gasification combustion mode, without tar, waste water and other waste discharges. The Widely Used Biomass Pellet Burner can be directly connected with biomass boilers, Biomass Heating and various industrial kilns.
