Tipos de bombas de vácuo

Uma bomba de vácuo é um dispositivo que extrai moléculas de gás de um volume vedado e mantém um vácuo parcial. Sua função é criar um vácuo em um volume, geralmente um de vários. Há vários tipos de bombas de vácuo, como bombas de raiz, bombas de diafragma, bombas de pistão rotativo e bombas centrífugas autoescorvantes.

A bomba de diafragma é uma bomba de vácuo seca de deslocamento positivo

As bombas de diafragma são um tipo versátil de bomba de vácuo. Elas podem ser instaladas em uma variedade de cenários, incluindo esvaziamento de contêineres, sucção positiva e mistura simultânea de fluidos. Seu desempenho depende da rigidez e da durabilidade do diafragma, que, por sua vez, depende do material.
Elas têm bom desempenho quando operam em modo seco. As bombas de diafragma funcionam de forma muito semelhante ao coração humano, e é por isso que são frequentemente usadas para criar corações artificiais. Além disso, a bomba de diafragma é autoescorvante e tem alta eficiência. Elas também são capazes de lidar com os líquidos mais viscosos e são usadas em quase todos os setores.
No entanto, esse tipo de bomba tem várias desvantagens. Uma delas é que elas são difíceis de reiniciar após uma queda de energia. Outra desvantagem é que elas podem gerar muito calor. Felizmente, esse calor é levado pelo fluxo de ar. Entretanto, esse calor se acumula na bomba de múltiplos estágios. Se isso acontecer, o diafragma ou o motor podem ser danificados. As bombas de diafragma que operam em dois ou mais estágios devem ser equipadas com válvulas solenoides para manter a estabilidade do vácuo.
As bombas de diafragma são uma boa opção para processos de secagem em que a higiene é importante. Essas bombas têm válvulas de retenção e diafragmas de borracha ou Teflon. As bombas de diafragma também são ideais para aplicações de alta viscosidade em que a sensibilidade ao cisalhamento é importante.

As bombas Roots são bombas centrífugas de método seco

As bombas Roots usam uma bomba de rotor de palhetas com duas palhetas contra-rotativas que se movem em direções opostas para movimentar o gás. Elas geralmente são a primeira opção para aplicações de processos de alto rendimento. Dependendo do tamanho e do número de palhetas, elas podem suportar até 10 Torr.
As bombas centrífugas têm várias vantagens, inclusive a capacidade de lidar com fluidos corrosivos e altas temperaturas. Entretanto, ao escolher uma bomba, é essencial optar por um fabricante de boa reputação. Essas empresas poderão aconselhá-lo sobre o melhor projeto de bomba para suas necessidades e oferecer um excelente suporte pós-venda. As bombas Roots podem ser usadas em uma ampla gama de aplicações industriais, incluindo química, alimentos e biotecnologia.
A bomba Roots é uma bomba centrífuga seca cuja geometria permite atingir altas taxas de compressão. Os rotores do parafuso são sincronizados por um conjunto de engrenagens de sincronização que permitem que o gás passe em ambas as direções e crie um estado comprimido na câmara. O gás pré-comprimido é descarregado por meio de uma conexão de pressão e resfriado com água. Algumas bombas também são capazes de aceitar gás de resfriamento adicional, mas isso deve ser feito com cautela.
O tamanho do impulsor desempenha um papel importante na determinação da altura da bomba. O diâmetro do impulsor determina a altura que a bomba pode elevar o líquido. A velocidade do impulsor também afeta a altura manométrica. Como a altura manométrica é proporcional à gravidade específica do líquido, a pressão de sucção disponível será proporcional à densidade do líquido. A densidade da água é de aproximadamente 1,2 kg/m3 e a pressão de sucção da bomba centrífuga não é suficiente para elevar a água.

A bomba de palhetas rotativas é uma bomba centrífuga autoescorvante

A rotary vane pump is a centrifugal pump with a circular pump head and a cycloid cam that supports the rotor. The rotor is close to the cam wall, and two side plates seal the rotor. Vanes in vane pumps are installed in these cavities, and the rotor rotates at high speed, pushing fluid in and out of the pump. The pump offers several advantages, including a reversible design and the ability to handle a wide variety of clean fluids.
Agknx Pumps manufactures a wide range of vane pumps that combine high performance, low cost, and easy maintenance. These pumps handle medium to high viscosity liquids up to 500 degrees Fahrenheit and 200,000 SSU.
The suction side of the rotary vane pump has a discharge port, and the valve prevents the backflow of the discharge air. When the maximum pressure is reached, the outlet valve closes to prevent the backflow of exhaust gas. The mechanical separation step separates the oil from the gas in the pump circuit and returns the remaining oil particles to the sump. The float valve then reintroduces these oil particles into the oil circuit of the pump. The gas produced is almost oil-free and can be blown out of a pipe or hose.
Rotary vane pumps are self-priming positive displacement pumps commonly used in hydraulic, aeration, and vacuum systems. Unlike gear pumps, rotary vane pumps can maintain high-pressure levels while using relatively low suction pressures. The pump is also very effective when pumping viscous or high-viscosity liquids.

Rotary piston pumps are dry method positive displacement pumps

Rotary piston pumps are dry positive displacement pumps designed to deliver high-viscosity fluids. They are capable of pumping a variety of liquids and can run dry without damaging the liquid. Rotary piston pumps are available in a variety of designs. Some are single shafts, some are two shafts and four bearings.
Positive displacement pumps operate slower than centrifugal pumps. This feature makes the positive displacement pump more sensitive to wear. Piston and plunger reciprocating pumps are particularly prone to wear. For more demanding applications, progressive cavity, diaphragm or lobe pumps may be a better choice.
Positive displacement pumps are typically used to pump high-viscosity fluids. This is because the pump relies on a mechanical seal between the rotating elements and the pump casing. As a result, when fluids have low viscosity, their performance is limited. Additionally, low viscosity fluids can cause valve slippage.
These pumps have a piston/plunger arrangement using stainless steel rotors. Piston/piston pumps have two cavities on the suction side. The fluid then flows from one chamber to the other through a helical motion. This results in very low shear and pulsation rates. The pump is usually installed in a cylindrical housing.

Rotary vane pump corrosion resistance

Rotary vane vacuum pumps are designed for use in a variety of industries. They feature plasma-treated corrosion-resistant parts and anti-suck-back valves to help reduce the number of corrosive vapors entering the pump. These pumps are commonly used in freeze dryers, vacuum ovens, and degassing processes. The high flow rates they provide in their working vacuum allow them to speed up processes and reduce the time it takes to run them. Plus, they have energy-efficient motors and silent volume. <br/While rotary vane vacuum pumps are relatively corrosion resistant, they should not be used for aggressive chemicals. For these chemicals, the most suitable pump is the chemical mixing pump, which combines two types of pumps to improve corrosion resistance. If the application requires a more powerful pump, a progressive cavity pump (eg VACUU*PURE 10C) is suitable.
Oil seals used in rotary vane pumps are important to pump performance. The oil seal prevents corrosion of the aluminum parts of the rotary vane pump and prolongs the service life. Most rotary vane vacuum pumps have a standard set of components, although each component may have different oil seals.
Rotary vane vacuum pumps are the most common type of positive displacement pump. They provide quiet operation and long service life. They are also reliable and inexpensive and can be used in a variety of applications.

Roots pumps are primarily used as a vacuum booster

Root vacuum pumps are mainly used as vacuum boosters in industrial applications. They need a thorough understanding of operating principles and proper maintenance to function properly. This course is an introduction to Roots vacuum pumps, covering topics such as pump principles, multi-stage pumps, temperature effects, gas cooling, and maintenance.
Roots pumps have many advantages, including compact and quiet operation. They do not generate particles and have a long service life. They also don’t require oil and have a small footprint. However, Roots pumps have several disadvantages, including relatively high maintenance costs and low pumping speeds near atmospheric pressure.
Root vacuum pumps are often used with rotary vane vacuum pumps. They work on the same principle, the air enters a conveying unit formed by two rolling pistons in the housing. The piston heads are separated from each other, and the air passes through the unit without being reduced until it is discharged. When the air in the next unit reaches a higher absolute pressure, it is expelled from the last unit.
Roots pumps can be classified as sheathed or sealed. Roots pumps with sealed motors are suitable for pumping toxic gases. They have less clearance between the stator and motor rotor and have a sealed tank.
