Vortex pump is from the pump in the future appeared in 1920, an important layout of the vortex pump includes the impeller, pump body, pump cover, and the annular flow channel formed by them. The transport medium from the suction pipe into the runner, through the impeller rotation to get energy, was delivered to the pipe extrusion, the pump to complete the course. Vortex pump operating principle, structure and characteristics of the shape of the centrifugal pump and other types of pumps are not the same. Is a small flow, high-lift pump, the ratio of n8 is usually less than 40. Vortex pump things flow down to 0.05L / s or less; large flow up to 12L / s, so that in some places can replace the centrifugal pump. When the specific speed Ns over 40, because its obey is much lower than the centrifugal pump, as less commonly used. Below to understand the vortex pump introduction and structure of it. Introduction and structure description of the vortex pump I. Introduction of the vortex pump: 1 The vortex pump is used to transport the liquid with the temperature from -20 ℃ ~ + 80 ℃, viscosity no more than 5 ° E, non-corrosive and no solid particles. Flow range: 1.73 m 3 / h ~ 16 9 m 3 / h Head range: 20 m ~ 115 m 2 Materials of the main parts of the vortex pump: ①The material of the pump body and the pump cover is HT20-40; ② The impeller and the shaft The material is generally 45. 3 vortex pump seal with soft packing and mechanical seal (not including 32w -75) in two forms, but with the pump with a mechanical seal, it should be made when ordering, the contract states. 4 vortex pump rotation direction from the pump to the motor direction to counterclockwise rotation. If the user needs, you can also rotate clockwise, but this time inhalation and pressure out of the role of the tube and the original provisions of the opposite. Second, the structure of the vortex pump Description: 1 pump body 2 pump cover 3 impeller 4 bracket with 5 claw-type suspension coupling parts 6 gland packing or single-ended seal cover 7 single-ended seal parts structure of the main components of the vortex pump A pump body, pump cover, impeller, bracket parts, sealing parts, and coupling parts. Pump selection, outlet (see installation diagram) through the connecting pipe becomes vertical upward. Impeller in the pump body and pump cover and maintain a certain gap. The size of the total gap can be adjusted with a paper pad, the impeller is free to move axially on the shaft, and the vortex pump can automatically adjust the clearance between the impeller and the pump body and the pump cover during operation. Vortex pump is a vane pump, although it belongs to the field of vane pumps, but its history, layout and characteristics of the shape of the curve and other centrifugal pumps and other pumps are quite different.
