The impeller is an important part of the sand pump, and its structure and form have a relatively large impact on the performance of the sand pump. It also plays a more important role in the selection of sand pumps and cannot be easily ignored.
Common sand pumps are centrifugal pumps. Centrifugal pump impellers mainly have the following four forms: (a) closed type; (b) front half open type; (c) rear half open type; (d) open type. Among them, (b) the front half-open type; (c) the rear half-open type can be collectively referred to as the half-open impeller.
The sand pump impellers are usually only closed and front half-open semi-open impellers. The other two styles are rarely useful.
Sand pump closed impeller
It consists of blades and front and rear covers. The closed impeller has higher efficiency and is more difficult to manufacture, and is widely used in wear-resistant sand pumps. The sand pump of the closed impeller is generally higher in lift than the semi-open impeller, which is suitable for the sand pumping environment that requires high head or long distance transportation. The impeller of this structure is mostly used in submersible sand pumps and horizontal sand pumps.
Sand pump semi-open impeller
General structure: It consists of the back cover and the blades. The impeller of this structure has low efficiency. Generally, the lift of the sand pump is only about 10 meters; it is much lower than that of the closed impeller. However, in the case of the same size of the impeller, without considering other factors, the particle flow capacity of the semi-open impeller is slightly better than that of the closed impeller. However, the specially designed large particle sand pump is also a closed impeller, and its flow capacity is higher than that of most semi-open impeller sand pumps. The impeller structure is only one of the factors determining the overcurrent capability, not all of them.
