Selection of high temperature resistant self-priming pumps
The high-temperature-resistant self-priming pump has excellent performance under high-temperature conditions and can stably transport high-temperature media. However, due to its special working environment, many factors need to be considered during the selection process to ensure the safe and efficient operation of the pump.
1. Key factors in selection
Medium properties: High-temperature resistant self-priming pumps need to be selected based on the temperature, corrosivity, viscosity and other characteristics of the medium. Different media have different requirements for pump materials and structures.
Flow and head: Determine the flow and head of the pump according to actual needs to avoid excessively high or low flow and head from affecting the performance of the pump.
Motor requirements: The motor is the core component of the high temperature resistant self-priming pump. The appropriate motor type, voltage level and protection level need to be selected according to the working conditions.
2. Precautions for model selection
Avoid cavitation: In high-temperature environments, the medium easily vaporizes and causes cavitation, which affects the performance of the pump. Therefore, the NPSH of the pump should be fully considered when selecting the type.
Material selection: Select appropriate pump body materials and sealing materials according to the properties of the medium to ensure that the pump has good corrosion resistance and sealing properties at high temperatures.
Installation and maintenance: The installation and maintenance of high-temperature resistant self-priming pumps are equally important. You should ensure that the pump is installed in a reasonable location, the pipelines are smooth, and regular maintenance is performed.
