Pump intrinsic characteristics and the pursuit of extrinsic characteristics
The intrinsic characteristics of the pump refer to the inherent characteristics of the product, including product performance, component quality, assembly quality, appearance quality, etc., or simply referred to as quality. At this point, it is the focus of many pump manufacturers that are currently trying to improve and improve. In fact, we can find that there are many products that fail to meet the factory inspection results after the factory inspections meet the requirements of the unit. The occurrence of such problems as overload, noise increase, use failure, or reduced life. The problem of the other aspects; the operating point or operating characteristics of the pump in practice, we call the pump's extrinsic or system characteristics.
When technicians design products, it often takes a lot of thought to improve the efficiency of one percent of a product. If the pump operation deviates from the high efficiency of the design, the actual operation efficiency is far more than one percent lower. Now, the pump manufacturer also supports the user's control equipment and complete sets of equipment including frequency conversion, and has actually been involved in the pursuit of the external characteristics of the pump. On this basis, focusing on the centralized control system of the pump and improving the operating efficiency of the entire pump and pumping station is a step up in the pursuit of the external characteristics of the pump.
From a sales point of view, the promotion of the product is to promote the intrinsic characteristics of the pump; while the focus on the external characteristics of the pump is that the manufacturer is not only selling products, but also marketing pump stations (set of projects). From the point of view of use, a good product must be a product suitable for the operating environment rather than a factory inspection.
Further development of mechatronics
Just like the development of science and technology. At present, the interdisciplinary and marginal disciplines in the field of science and technology are becoming more and more abundant. Interdisciplinary joint research is a very common thing, as is the technological development of pump products.
Taking the shielded pump as an example, the problem of canceling the shaft seal of the pump must be started from the structure of the motor. It is only limited to the pump itself. It can solve the noise problem of the pump. In addition to solving the flow and vibration of the pump, it needs to be solved at the same time. The noise of the motor blades and the noise of the electromagnetic field; to improve the reliability of the submersible pump, measures such as leakage protection and overload protection must be added to the submersible motor; the efficiency of the pump must be improved by the use of control technology. All of these indicate that to develop the pump technology level, we must start from the supporting motor and control technology, and comprehensively consider to maximize the comprehensive level of mechatronics.
Accelerated utilization of new materials and new processes
The use of new materials and processes has been a major factor driving the development of pump technology for more than a decade. Pump materials from cast iron to special metal alloys, from rubber products, ceramics and other non-metallic materials to engineering plastics, have played a prominent role in solving the pump's corrosion resistance, wear resistance, high temperature and other environments. At the same time, the use of new processes makes it easier to apply new materials to the pump components and even the entire pump.
For example, some foreign manufacturers have designed and introduced pumps made entirely of engineering plastics. Compared with pumps made of general metal materials, the pump is not inferior in strength and superior in corrosion resistance and wear resistance. Another example is the use of new surface coating techniques and surface treatment techniques to solve the problem of corrosion and wear of the pump. The further development of new materials and the application of new processes will be more widely used in the pump field.
