InPower Oil free screw vacuum pump is through driving & driven rotor rotating to enlarge the sealed suction section to inhale gas . After the pumped gas enter into pump chamber, the sealed section will move from suction end to discharge end along with the driving & driven rotor rotation, pressure rises steadily and there is no intermediate exhaust phenomenon.When sealed space is connected to discharge port, the gas in the discharge passage is backlash into the pump chamber, causing the gas pressure and temperature in the pump chamber rising, and producing airflow noise.With the pump continues working,volume of sealed space begins to become smaller and smaller and the gas in the pump chamber is continuously discharged.There is free-oil lubrication for pump chamber . So it can get a clean vacuum. Anti-corrosion should be done when screw vacuum pump suck corrosive gases.
Oil Free Screw Vacuum Pump are positive displacement pumps that consist of two mating screw rotors that rotate in opposite directions; this rotation is what moves the trapped air/gas along the length of the screws. As the trapped gas moves along the screws, it becomes compressed and is eventually discharged on the opposite end. It's important to note that these vacuum pumps are designed to have no metal-to-metal contact within the pump housing, which results in minimal wear on the pump and less equipment overhauls.
Screw pumps can be either oil-sealed or dry. Oil-sealed screw pumps use oil for lubrication, sealing, and cooling purposes; they are ideal for rough vacuum applications that have no clean vacuum requirements, including woodworking and plastics. Dry screw pumps do not use oil/lubricant in the chamber. Rather, these are typically air-cooled and are free of any oil emissions, and can also achieve higher vacuum than oil-sealed screw pumps.

These pumps are designed to handle wet and dry materials, making them versatile and effective. Additionally, they eliminate the risk of oil contamination in sensitive applications like food processing or pharmaceuticals.
Steel Degassing: In the steel industry, the use of oil free screw vacuum pump for degassing processes is crucial. These pumps play a vital role in removing impurities and unwanted gases from molten steel, resulting in the production of high-quality steel with desired properties. The innovative design of oil free screw vacuum pump allows them to operate at high vacuum levels and provide efficient degassing by pumping speeds. This ensures the reduction of gas content, leading to an overall improvement in the quality of steel products. The industrial application of oil free screw vacuum pump in steel degassing is an ideal solution to achieve the desired steel properties through the compression and removal of unwanted gases.
Vacuum Furnaces: Vacuum furnaces are crucial in industries such as aerospace, medical devices, and electronics. They create and maintain a vacuum environment essential for various processes. Oil free screw vacuum pump play a vital role in this setup. These positive displacement pumps use a unique pumping mechanism to compress the gas and achieve high vacuum levels. The compression of the gas is facilitated by the rotational movement of the screw rotors, which operate in opposite directions within a tight clearance. This innovative design enables the pump to handle high temperatures and process contamination effectively. It also ensures efficient pumping speed and ultimate pressures. However, maintenance and troubleshooting are important to optimize performance. Regular inspection of shaft seals, bearings, and the pump housing, as well as monitoring discharge temperatures and lubrication, can help prevent issues. By understanding the different types of oil free screw vacuum pump and their advantages and disadvantages, industries can make informed decisions for their specific vacuum furnace applications.
Vacuum Coating: In vacuum coating processes, a crucial component is the screw vacuum pump. These pumps utilize two intermeshing screws to compress gas and create a vacuum environment. With their innovative design, oil free screw vacuum pump offer high pumping speeds and low noise levels, making them ideal for various applications, including electronics, optics, and automotive industries. The thin film deposition achieved through vacuum coating plays a vital role in enhancing product performance and aesthetics. To ensure optimal performance and longevity, proper maintenance and cleaning of oil free screw vacuum pump are essential. By adhering to these maintenance practices, process contamination can be minimized, allowing for efficient and reliable operation. Oil free screw vacuum pump are undoubtedly an integral part of the vacuum coating process, facilitating the creation of high-quality and precise coatings.
An oil-free screw is a type of vacuum pump that uses a pair of intermeshing screws, or rotors, to compress and evacuate gases. Unlike other types of vacuum pumps, oil-free screws do not use oil for lubrication or sealing. Instead, the rotors are designed and manufactured to operate without the need for oil, resulting in a clean and efficient vacuum pump that can handle high water vapor loads.
The operation of an oil-free screw vacuum pump begins when the rotors are driven by an electric motor. As the rotors rotate, they create pockets of gas within the pump housing. These pockets of gas are then compressed and evacuated as the rotors continue to rotate.
One of the key features of an oil-free screw vacuum pump is the design of the rotors. The rotors are typically made of a high-strength, low-friction materials such as cast iron or anodized aluminum. This allows the rotors to operate without the need for lubrication, reducing friction and wear.
Another important feature of oil-free screw vacuum pumps is the use of a dynamic seal. Because there is no oil used for lubrication or sealing, an oil-free screw vacuum pump must use an alternative method to seal the rotors and prevent the escape of gases. This is typically achieved using a dynamic seal, which is a flexible seal that moves with the rotors and maintains a tight seal around the rotors. The addition of purge gas at the sealing points can provide additional protection in harsh applications.
Oil free screw vacuum pump is generally twin-screw structure. Screw type vacuum pump is a kind of pumping equipment which is driven by a pair of asymmetric screw rotors in the pump cavity in a synchronous and high-speed reverse operation, and periodically changing the volume between teeth.
Its main structure includes screw rotor, bearing, pump body, seal, etc. After fine dynamic balance correction, the screw rotor is supported by bearings and installed in the pump cavity. The screw and screw maintain a strict clearance. When the pump works, there is no friction between each other, the operation is stable, the noise is low, and there is no need for lubricating oil in the cavity. Therefore, the oil free screw vacuum pump can remove large amounts of water vapor and a small amount of dust. It has the advantages of high vacuum limit, low power consumption, energy saving and maintenance free.
Long lines within a lead which can complete suction, compression, exhaust process, less lead, which can effectively reduce the volume and weight of the pump, apply to the field of large pumping speed, but its complex type line, need special props and special.
There is no compression in the cavity of uniform pitch oil free screw vacuum pump, which can easily discharge solid particles and condensable gases, but its exhaust temperature and energy consumption are high. Variable pitch oil free screw vacuum pump cavity has compression, low exhaust temperature, low energy consumption, but dust particles and condensable gas tolerance is not as good as equal pitch.
When purchasing an oil free screw vacuum pump, you must first determine the vacuum required to work, otherwise, the vacuuming requirements will not be met, and the work requirements will not be met. Under its working pressure, the vacuum pump should be able to exhaust all the gas generated during the process of the vacuum equipment. Combine the vacuum pump correctly.
The pumping rate should be slightly greater than the required pumping rate when selecting the model. If the demand is high, the vacuum pump selected should be higher than the required vacuum, so that it can better meet the requirements. The different pump has different working pressure ranges. Finally, look at whether the extracted gas is corrosive, corrosive gas will corrode the pump, and special materials must be used to meet the demand.
