Compressed air driven vacuum pumpA working chamber composed of a pair of parallel spiral rotors and a pump body, with no friction between the rotors and the pump body and maintaining a certain gap. A sealed chamber is formed between the two rotors and the pump body, and when the rotors rotate, the gas in the sealed chamber is continuously squeezed and carried to the exhaust port for discharge.
A vacuum pump with multiple leads is equivalent to a multi-stage pump connected in series. Since there are no internal channels between each stage of the pump, the gas is directly pushed from the suction side to the exhaust side. Therefore, it is not easy to block and is easy to clean when extracting condensable gases, gases with dust and particulate matter.
The pump chamber of a vacuum pump is oil-free, so the vacuum pump is an oil-free dry vacuum pump. It has incomparable performance in situations where oil-free cleanliness is required in the semiconductor and electronic industries, as well as in solvent recovery processes in chemical and pharmaceutical industries. It can better replace rotary vane vacuum pumps and slide valve vacuum pumps. Multiple lead vacuum pumps are equivalent to multi-stage pumps connected in series. Since there is no internal channel between each stage of the pump, the gas is directly pushed from the suction side to the exhaust side. Therefore, it is not easy to block and easy to clean when extracting condensable gases, gases with dust and particles.
The impeller is directly installed on the extended shaft of the motor, with a short axial dimension and compact structure,Compressed air driven vacuum pumpReasonable configuration of motor bearings can effectively balance the radial and axial loads generated by pump operation, ensuring smooth pump operation, low vibration, and low noise. The pump is a vertical structure with the same inlet and outlet diameters and located on the same centerline. It can be installed in pipelines like a valve, with a compact and beautiful appearance, small footprint, and low construction investment. If a protective cover is added, it can be used outdoors.
The installation and maintenance of compressed air driven vacuum pumps are convenient, without the need to dismantle the pipeline system. All rotor components can be extracted by removing the pump coupling nut. The series and parallel operation of the pump can be adopted according to the requirements of flow rate and head, and the vertical and horizontal installation of the pump can be adopted according to the requirements of pipeline layout.
