General procedure for selecting LQB insulated asphalt pumps and key factors to consider

Thread Content

1. Based on various factors such as the arrangement of the equipment, terrain conditions, water level conditions, operating conditions, and comparisons of economic options. 2. Consider selecting horizontal, vertical, and other types (right-angled, vertical, upright, submersible, self-priming, gear-driven). Horizontal pumps are easy to disassemble and assemble; 3. they are easy to manage, but they are large in size; 4. they are relatively expensive; 5. they require a lot of space. 5. Determine the specific model of the LQB insulated asphalt pump. Once the series of pump to be used is selected, the specific model can be identified using the two main performance parameters: maximum flow rate and head, with a 5%–10% increase added to these values, by referring to the model chart or the characteristic curves of that series. 7. After the model of the LQB insulated asphalt pump is determined, for pumps that are used to transport liquids with physical and chemical properties similar to those of water, it is necessary to refer to relevant product catalogs or samples, and make adjustments based on the performance table or performance curve of that model, to determine whether the normal operating point falls within the optimal operating range of the pump. 9. Determine the number of LQB insulated asphalt pumps and the backup ratio: For pumps that are operating normally, generally only one pump is needed, as one large pump is equivalent to two smaller pumps operating in parallel (in terms of head and flow rate). The efficiency of a large pump is higher than that of smaller pumps; therefore, from an energy-saving perspective, it is better to use one large pump rather than two smaller ones. However, in the following situations, it may be advisable to use two pumps in parallel: when the flow rate is very high and a single pump is not sufficient to meet it.
