Detailed introduction of imported scroll pump
Vortex pump is also called vortex pump, regeneration pump, etc. Because it is by the impeller rotation when the liquid vortex motion and suction and discharge of liquid, so called vortex pump. According to different types of vortex pump, it can be divided into single-stage vortex pump, centrifugal vortex pump, stainless steel vortex pump and other vortex pumps.
At present, the flow rate of general vortex pump is 0.2 ~ 27m3 / h. The working principle of general vortex pump is that when the prime mover drives the impeller to rotate in the pump through the shaft, the liquid enters the flow channel by suction, and is thrown into the annular flow channel by the centrifugal force of the rotating impeller, making the liquid rotate in the flow channel. Because each liquid particle is affected by centrifugal force, the liquid inside the impeller is greatly affected by the centrifugal force, while the liquid in the flow channel is less affected by the centrifugal force. Due to the different centrifugal force, the liquid will make longitudinal vortex motion. The liquid circulates through the channels between the blades repeatedly by means of longitudinal vortices (Fig. 1-35). Each time the liquid passes through the passage between blades, the lift is increased once, and finally the liquid is pressed out and discharged.
After the liquid is discharged, a local vacuum will be formed in the channel between the blades, and the liquid will continuously enter the impeller from the suction inlet and repeat the above motion process. In this way, the vortex pump suction liquid, while discharging liquid, so as to continue to work. From the working principle of general vortex pump, we can see that it is like the role of multi-stage centrifugal pump, each blade channel is equivalent to one stage, and the energy increases once the liquid passes through the channel. Therefore, the head of general vortex pump is 2-5 times larger than that of centrifugal pump under the same impeller diameter, so it is a kind of pump with high head and small flow. Compared with the centrifugal pump with the same performance, the vortex pump has small volume and light weight; compared with the positive displacement pump with the same head, its size is much smaller and its structure is much simpler. Therefore, the general vortex pump has the advantages of simple structure, compact, small volume, light weight and low cost.
