Non-blocking pump impeller structure design

With the development of science and technology, the application area of ​​pumping solid substances is expanding, such as sewage sludge, mud pulp, ash residue, grain starch, beet fruit, shellfish and so on. There are two main requirements for pumps that deliver these substances: First, there is no blockage and second, wear resistance. The main wear-resistant and material-related, non-clogging depends mainly on the structure of the impeller. Currently as the main structure of non-clogging pump impeller are: 1. Open or semi-open impeller; 2. Swirl impeller; 3. Single (dual) flow impeller; 4. Spiral centrifugal impeller. These non-clogging impeller has its own characteristics, the application is not the same, as follows: Open or semi-open impeller - such as increased wear gap, pump performance decline, and no blockage poor performance, can not transport large particles, long Fiber material; Swirl impeller - no clogging performance, good wear resistance, suitable for conveying large particulate matter, but nondestructive, the destruction of the transport material is large, can transport gas containing liquids, not suitable for conveying long fiber containing material Of the liquid; single-flow impeller - on the transport of non-destructive material, non-clogging performance, suitable for conveying large particles of long fiber material, and good wear resistance, but the balance of high demand, poor balance operation; Shuangliu Road impeller - passing capacity slightly worse than the single-runner, but because of symmetrical runner, balanced performance, smooth operation, suitable for high-lift, high-flow pump; Spiral centrifugal impeller - good non-blocking, suitable for Liquids containing particulates and fibrous substances are less destructive to the transport material, ie, are non-destructive, but require a higher level of balance.
