In the performance evaluation of deep bore well submersible water pump, the speed is a crucial parameter. It directly affects the pumping capacity and head of deep bore well submersible water pump, and then affects its efficiency in various application scenarios. In this paper, the effect of rotational speed on the flow rate and head of deep-well submersible pump is described in detail, and how to optimize the performance of deep-well submersible pump by adjusting rotational speed is discussed.

First, we need to understand the relationship between speed and the flow rate of a deep bore well submersible water pump. The flow rate of a deep bore well submersible water pump is the amount of water pumped per unit time, usually in cubic meters per hour (m³/h). In the design of deep bore well submersible water pump, there is a positive correlation between flow rate and speed. In short, when the speed increases, the speed of the pump blade rotation is accelerated, which increases the amount of water inhaled and discharged per unit time, so that the flow rate increases. On the contrary, when the speed is reduced, the flow rate will also be reduced.

However, flow rate is not the only criterion to measure the performance of deep bore well submersible water pumps. Head, the height at which the water is lifted, is also an important performance indicator. There is also a certain relationship between head and speed. Under normal circumstances, as the speed increases, the head will also increase accordingly. This is because when the speed increases, the driving force of the pump blade on the water is increased, so that the water can be lifted to a higher position. However, this relationship is not linear, when the speed increases to a certain extent, the increase rate of head will gradually slow down, and there may even be a drop in head. This is because too high a speed will cause an increase in the friction loss between the pump blade and the water flow, thereby reducing the head.

Therefore, in order to optimize the performance of deep-well submersible pumps, we need to find a suitable speed range. In this range, the flow and head of the deep bore well submersible water pump can reach great state. How to find the right speed range? This usually needs to be determined according to the specific application scenario and the design parameters of the deep bore well submersible water pump.

In practice, we can optimize the performance by adjusting the speed of the deep bore well submersible water pump. A common method is to change the power supply frequency of the deep bore well submersible water pump through the frequency converter, and then adjust its speed. The frequency converter can precisely control the speed of the deep bore well submersible water pump according to the actual demand, so as to achieve the accurate adjustment of the flow rate. For example, when a large flow rate is required, the speed can be appropriately increased; When high head is required, the speed can be reduced appropriately. This can not only meet the needs of different applications, but also reduce energy consumption and extend the service life of deep bore well submersible water pumps.

In short, speed and pipe diameter are the key factors affecting the performance of deep bore well submersible water pump. By adjusting the speed and selecting the appropriate pipe diameter, we can optimize the performance of the deep bore well submersible water pump and improve the pumping efficiency and head. In practical applications, we should determine good combination of speed and pipe diameter according to the specific needs and the design parameters of the deep bore well submersible water pump to achieve good performance and economic benefits.
