Precautions when purchasing slurry pump selection
Slurry pump can be widely used in the mining, electric power, metallurgy, coal, environmental protection and other industries to transport slurry containing abrasive solid particles. Such as metallurgical beneficiation plant slurry transportation, thermal power plant ash removal, coal washing plant coal slurry and heavy medium transportation, dredging rivers, river dredging and so on. In the chemical industry, some corrosive slurries containing crystals can also be transported. So what issues should you pay attention to when choosing a slurry pump? I will introduce it to you today.
First, the performance aspect
The performance of the slurry pump mainly refers to the flow rate, head and NPSH of the pump, followed by the speed, power and pump efficiency. The flow rate and head of the slurry pump are often taken seriously, but its NPSH is often neglected. In fact, when the cavitation performance is not met, the pump performance will be reduced and the life will be shortened. use.
Second, process and installation aspects
In addition to the above performance requirements, it must also meet the temperature, properties, viscosity, corrosiveness and impurities of the slurry pump transport medium, and also consider the installation requirements, and strictly follow the instructions.
Third, the economic aspect
Consider the economics of both one-time investment and long-term cost of use. One-time investment refers to the purchase of pumps, motors, pipelines and construction investment of pumping stations. The economics of long-term use are considering power consumption, pipeline hydraulic loss, pump and motor life and maintenance costs.
Whether the selection is correct or not directly affects the use of the slurry pump and the economy. If the selection is not correct, the life of the pump will be shortened and the cost of purchase will increase. Therefore, the selection of pumps and motors is an important task.
