The design of oil-lubricated rotating blades, supplemented by perfect manufacturing materials and the most advanced precision manufacturing, ensures that it can obtain stable high vacuum during continuous operation. Efficient air extraction system and integrated oil return pipeline combined with advanced exhaust filter ensure clean exhaust without oil pollution. When equipped with an optional gas ballast valve, it can handle more steam. When the vacuum pump is turned off, the check valve in the inlet flange can prevent air from flowing back into the vacuum chamber. The pump body is directly driven by a standard motor with flange connection, and the energy efficiency grade of the motor is IE2. Two claw rotors of claw vacuum pump and compressor claw vacuum pump rotate in opposite directions in the cylinder. Air and process gas are sucked, compressed and discharged by claw rotor. Claw rotors do not touch each other or the cylinders in which they run. The tight gap between claw rotor and cylinder not only optimizes its sealing performance, but also ensures continuous high pumping speed. The synchronous gear ensures the precise synchronous operation of the rotor. Busch's mink claw vacuum pump is directly driven by an asynchronous motor with flange connection, and its energy efficiency grade is IE2. Mink coat
Dry screw vacuum pump-industrial cobra industrial dry screw vacuum pump can run efficiently in many industrial fields. This model has demonstrated many years of experience in oil-free vacuum technology, and adopts traditional bearing system, which is an ideal choice for processing technology. COBRA Industry Dry Screw Vacuum Pump-Semiconductor COBRA Semicon Dry Screw Vacuum Pump provides an effective solution for demanding semiconductor, solar energy, flat panel display production and coating industries. There are different versions: DS (industry standard, airtight, traditional bearing system), BA (airtight, suspension bearing system, air-cooled type), BC (airtight, suspension bearing system, water-cooled type). All these vacuum pumps are specially designed for complex applications in the semiconductor industry. Roots vacuum pump Panda and Puma Roots pump are oil-free vacuum pumps, which need to be used together with the backing pump, and are suitable for all coarse vacuum and high vacuum applications requiring large air intake. This enhanced vacuum pump greatly improves the output of the backing pump.
Puma/Panda series vacuum pumps: WP/WPA (industrial, standard type), WV (industrial, with bypass valve), WY (semiconductor, airtight), WZ (semiconductor, with bypass valve, airtight). The working modes of dry rotary vane vacuum pump and compressor Seco vacuum pump are based on the mature rotary vane technology principle. Because of the use of self-lubricating rotating blades, there is no need for working fluid lubrication. Completely adopts oil-free dry compression. Through perfectly matched materials, special graphite rotating blades in the cavity, effective heat dissipation and advanced precision machining technology, high vacuum during continuous operation can be realized. Seco Roots Blower Tyr Three-lobe Roots Blower works according to the Roots system principle: two parallel rotors run in opposite directions in the pump body. The pumping medium is sealed between the rotor and the pump chamber, compressed by the rotary motion of the rotor, and pumped to the exhaust port. The air inlet of the fan is equipped with an air inlet filter with integrated silencing function. The compressed medium will also be discharged after being treated by the exhaust muffler before being discharged by the fan. The driving device consists of a motor and a V-belt. V-belt drive mode can accurately adjust the fan speed to match the production process. Liquid ring vacuum pump and compressor liquid ring vacuum pump usually use water as working medium. The biasing blade rotates in a pump chamber partially filled with liquid. The centrifugal force generated by the rotating motion of the blades makes the liquid in the pump cavity form a liquid ring. Gas is transported in the space between each blade and the liquid ring. Due to the offset of the impeller, the space increases, and the production gas is sucked through the suction groove; As the impeller continues to rotate, the space decreases, so that the gas is compressed and discharged through the discharge groove. The vacuum pump can operate through the open loop or closed loop of water circulation. Side-flow Fan Samos Samos Side-flow Fan works according to the pulse principle, and the kinetic energy generated by rotating impeller is transferred to the pumping medium and converted into pressure. The medium is compressed in the side channel formed by the impeller directly installed on the shaft of the driving motor and the aluminum shell, and then discharged through the muffler on the pressure side. The medium is compressed in the side channel formed by the impeller directly installed on the shaft of the driving motor and the aluminum shell, and then discharged through the muffler on the pressure side. Scroll vacuum pump Fossa scroll vacuum pump is mainly composed of fixed scroll and driving scroll. Drive the scroll to rotate in the fixed scroll to generate rotary conveying function, suck gas from the outer edge of the scroll, then compress it between the two scrolls and convey it to the center of the scroll. Turbo-molecular vacuum pump Busch Turbo-molecular vacuum pump TM 1 100-2200 A adopts the working principle of turbine. The rapidly rotating turbine blades rotate between the stator blades. This rotation transfers kinetic energy to the disordered gas particles in the vacuum pump, and then transfers gas molecules from the air inlet to the exhaust port of the vacuum pump through compression. Turbo diffusion vacuum pump The basic components of Gu Ran Gu Ran diffusion vacuum pump are a cylindrical pump and a heatable bottom. Heatable oil is used as the working fluid of the pump. Oil vapor rises into the nozzle system, and after several steam flow stages, it is discharged from the system under high pressure. Molecules in industrial waste gas are captured by these steam flows and move down to the outlet of the backing pump. Oil vapor condenses in the water-cooled pump unit and directly returns to the bottom of the unit. With its multi-stage and innovative nozzle concept, Gu Ran diffusion vacuum pump can provide extremely high and stable pumping speed. Vacuum system The vacuum system seeks the most suitable vacuum solution by fully understanding the factors that affect the selection. Puxu's system engineers consider various requirements in the design process, and according to their experience in many installation projects around the world, tailor-made vacuum systems for customers.
