First, the role of the water pump elbow
Pump elbow as an important part of the pump system, its role is mainly in the following two aspects:
- Change the direction of water flow
The most basic role of the pump elbow is to change the direction of water flow, water flow from the pump output port for steering, so as to meet the industrial, civil and other different areas of the direction of water flow requirements. Therefore, the curvature angle of the pump bend should be set according to the needs of specific occasions.
- Reduce water velocity
Another role of the water pump bend is to reduce the speed of water flow through the role of curvature, this is because in the bend, the water flow through the curve radius is reduced to produce centrifugal force, resulting in the head of the water flow slows down the flow rate. This effect helps to reduce water hammer and noise in the water flow, but also to improve the efficiency of the pump, reduce the pressure loss of the pipeline.
Second, the importance of water pump bends
Although the water pump bends in the pump system only accounts for a small part, but it has a great impact on the operational stability of the entire system, efficiency and life. Specifically manifested in the following aspects:
- Stable transport of water
Pump operation stability for the delivery of water is very important, while the pump bends directly determine the flow of water import and export flow linearity. Normal pump bending system to maintain the smooth delivery of water without shaking, jamming, water impact and other phenomena.
- Improve the efficiency of the pump
Water flow in the pipeline will form a certain inertia resistance, but also by viscous resistance and friction resistance and other effects. The role of the pump bends is to reduce these resistances, improve the overall efficiency of the pump. Therefore, in the installation and maintenance of the pump system, the setting and location of the elbow is very critical.
- Reduce noise and water hammer
Water pump bends can effectively reduce water hammer and noise by reducing the speed of water flow. In addition, the reasonable setting of the radius and angle of the bend can also play a role in reducing water hammer and noise. This not only reduces the maintenance cost of piping, but also better protect the pump equipment.
In short, although the pump bend is a very small component of the pump system, but it has a very important role. For different application scenarios, the setup and location of the pump elbow will be different. Therefore, in the design, installation and maintenance of water pump systems, need to pay great attention to the role and importance of water pump bends.
Third, the advantages of the elbow
- Flexible: bends can be made into a variety of different bending angles and radii as needed. This makes it can be widely used in a variety of different pipeline connection occasions, such as industrial piping, construction piping and so on.
- Strong adaptability: the bend can be adapted to a variety of materials for pipe connection, such as stainless steel, carbon steel, copper, aluminium and so on. At the same time, it can also be adapted to different piping applications, including high temperature, high pressure, corrosion and other environments.
- Convenient installation: the installation of the elbow is relatively simple, you can use threaded connections, flange connections and other ways to quickly install, greatly saving the installation time and labour costs.
Fourth, the shortcomings of the bend
- Increase in energy consumption: Compared with straight pipes, there are more bends in the bend, so the water flow through the bends there will be a greater hydraulic resistance, thereby increasing the pump, piping and other equipment, energy consumption.
- Increased costs: the production of pipe bends need to go through a number of heat treatment, cooling, processing and other processes, so the production cost is higher. In addition, due to the special design of the elbow, also need to carry out professional manufacturing and processing, so the cost is further increased.
