1. Energy saving of the pump itself
Pump design and manufacturing unit in the process of designing and manufacturing pumps, design and manufacturing personnel should have energy-saving awareness in their minds, as the design and manufacturing units of pumps, they have the responsibility to provide consumers with high-efficiency and energy-saving pump products. The design unit of the pump should select an excellent hydraulic model when designing, study the scientific and efficient hydraulic design method, and in the design process, it is necessary to carry out the reliability test of the pump and the material selection test of the product, so as to improve the efficiency of the pump product. In the manufacturing process, the pump manufacturing unit should formulate its own enterprise standards that are higher than the national mechanical standards, and try to reduce the loss of hydraulic power. In the manufacturing process, each process is strictly controlled, the roughness of the overflow parts is reduced as much as possible, the gaps are carefully handled, and the gap value is appropriately reduced, so as to improve the efficiency of the pump and achieve the purpose of energy saving of the pump.
2. Improve the energy saving of the pump system
In addition to paying attention to the energy saving of the pump itself, we should also pay attention to the development and research of the energy-saving technology of the whole system, the efficiency of the pump and the related supporting facilities also have a great relationship, and the system energy-saving technology is even more important than the energy-saving technology of the pump itself. The research on the energy-saving technology of the system should focus on the system engineering design from the perspective of energy saving, so that all aspects of the system can achieve the best matching effect, and the entire pump system can play its own maximum efficiency in the operation process of the pump. In this regard, it mainly includes the connection of the pump and the motor, the design of the pipe network, the connection and coordination of related accessories, etc., so that they can play their greatest role, so as to improve the efficiency and service life of the pump system.
3. Energy saving in the operation of the pump
The efficiency of the pump itself has been improved, and the entire pump system has been designed for energy saving, but this is only one aspect, and another very important aspect is in the operation of the pump. In practice, often due to the improper use of the pump, the pump can not play its role efficiently, and the use environment of the pump is very complex, different environments require different process flow and process parameters, and these aspects should be flexibly adjusted in the process of use. For example, when adjusting the pump system, it is necessary to pay attention to reducing the energy loss as much as possible, and reduce the use of throttling adjustment, which can solve the problem from the angles of angle change, speed change, turning, etc., so as to ensure that the motor and the pump can work efficiently. When installing the oysters of the water pump, it is necessary to adjust the angle of the consumption impeller for variable angle adjustment according to the needs of the specific use environment, and reasonably determine the installation angle of the blades, so that the water pump can work efficiently. Turning adjustment refers to the adjustment of the water pump by turning the impeller diameter, which is the simplest and one of the most energy-saving measures in the consumption of Bo, there is a common sense in the turning adjustment that the flow, head, and shaft power before and after the turning impeller are proportional to the impeller diameter, diameter square, and diameter cubic before and after turning. One of the problems that should be paid attention to when using turning adjustment is that the adjustment should be adjusted within a safe range, and the adjustment cannot be carried out indefinitely. Variable speed adjustment is the most direct and commonly used adjustment method in daily use, which will not produce power loss, and directly change the performance of the pump through the change of pump speed. In daily life, the main ways to achieve it are through gear gearbox, belt drive, frequency conversion, motor and so on. The most ideal way in these ways is frequency conversion speed regulation, which has the advantages of high efficiency, stepless speed adjustment and wide speed regulation, but the disadvantage in the application is that the investment is higher.
4. Energy saving in the use of water pumps by units and individuals
In the specific use environment, a reasonable pump system was selected, and in the process of operation and use, the use of units and individuals should also pay attention to establish a sense of energy conservation and carry out strict management, so as to make the pump achieve energy saving in the process of operation. At the same time, in the process of functioning, the pump system should be maintained and maintained frequently, so that the pump system can be in the best operating state, and the problems in the pump system are found through the usual maintenance, and the maintenance is carried out, which not only prolongs the service life of the pump system, but also can receive good energy-saving benefits.
With the development of modern technology, some new design methods, advanced casting and processing technology have also been applied in production, which has improved the efficiency of the pump and promoted the development of energy-saving work. With the improvement of people's awareness and the progress of technology, I believe that these problems in the current energy-saving work of pumps must be solved, and the prospects of energy-saving work of pumps are very good.
