The advantages of using vacuum pumps for repairing and maintaining Puxu screw pumps include: Vacuum pumps are a type of rotary pump that differs significantly from other conveying pumps in terms of design, application, and operating environment. They encompass various types such as water ring pumps, reciprocating pumps, slide valve pumps, scroll pumps, Roots pumps, and diffusion pumps. Each pump has its unique operating method, yet they are an indispensable pump type across various industries today.
Certainly, here is the translation: You might be wondering, what are the advantages of using vacuum pumps?
Wide range of pressure with high suction capacity;
(2) The rotor exhibits excellent geometric symmetry, resulting in minimal vibration and smooth operation. There are gaps between the rotors and between the rotors and the housing, eliminating the need for lubrication. This reduces frictional losses, significantly lowering the driving power required and enabling higher rotational speeds.
(3) No oil sealing or lubrication is required within the pump cavity, reducing oil vapor contamination of the vacuum system.
(4) No compression inside the pump chamber, without an exhaust valve. The structure is simple and compact, insensitive to dust and steam in the pumped gas.
(5) Low compression ratio, poor vacuuming effect on hydrogen.
(6) The rotor surface is a complex curved cylindrical shape, making it difficult to process and inspect.
