Split case pump is a kind of general-purpose mechanical equipment with a wide range of applications. It is widely used in petroleum, chemical, electric metallurgy, mining, marine, light industry, agriculture, civil and defense sectors, and plays an important role in the national economy.
The so-called rational selection of split case pump is to comprehensively consider the comprehensive technical and economic indicators such as the investment and operating costs of the pump unit and the pump station, so that it conforms to the principles of economy, safety and application. Specifically, there are the following aspects:
1. The flow rate and head requirements must be met, that is, the operating point of the pump (the intersection of the characteristic curve of the device and the performance curve of the pump) is required to be kept in the high-efficiency interval, which saves power and is not easy to damage the machine.
2. The selected pump has to be small in size, light in weight, cheap in cost, and has good characteristics and high efficiency.
3. It has good anti-cavitation performance, stable operation and long service life.
4. The selected pump has less engineering investment and low operating cost.
