With the continuous advancement of technology, gear pump products are bound to develop in the direction of intelligence, able to monitor parameters such as pressure, flow, temperature and vibration; to assess the condition of the shaft, bearing and seal of the pump; Causes for diagnosis, etc. The technological development of the pump industry will focus on designing electronic control systems, improving drive devices and seeking new materials.

(1) To develop gear pump products in the direction of integration of machines, electricity, and instruments, whether it is a general-purpose pump such as a small domestic pump or a building pump, or a process pump used in a large-scale petrochemical, electric power or other industrial device. The continuous development of the integration of electricity and instrumentation has enabled the pump products to be more efficient and energy-efficient, more convenient to use and maintain, increase reliability, prolong life, and bring greater benefits to users.

(2) Development in the direction of large-scale and high-speed development With the development of power plants, petrochemical plants, and water conservancy projects in the direction of large-scale and large-scale development, pumps as their supporting products are bound to develop in the direction of large-scale and high-speed.

(3) To meet the needs of different working conditions and applications in the direction of multi-species and multi-purposes, pump products are bound to expand their specifications and expand their performance. At present, domestic pump products still need to be further improved in terms of their specifications, varieties, and uses. For example, for high-pressure, low-flow pumps, mixed-acid pumps, and highly corrosive chemical slurry pumps, it is necessary to continuously develop new varieties.

(4) The scientificization of theory and design methods Strengthen the basic theoretical research of the pump, pay attention to the interpenetration of interdisciplinary, marginal, and emerging disciplines. The theoretical research focuses on the measurement, numerical simulation and performance prediction of the internal flow of the pump, the numerical calculation of the one-dimensional viscous flow, the theory and application of multiphase flow, the optimization of pump design and the diversification of design.

(5) Development and promotion of CAD, CAM, and CIMS technologies The high-tech production and manufacturing are fundamental guarantees for products that are "fair and inexpensive." By using advanced computer-aided design and computer-aided manufacturing technology, not only the design quality of the product is guaranteed, but also the design cycle is shortened, the product design capability is greatly improved, the design scheme is optimized, and the product reliability is ensured. At the same time, the application of computer manufacturing integrated system (CIMS) and virtual technology has greatly shortened the production cycle of pump products and ensured the performance of the products.

(6) Sealless pump technology Sealless pumps include magnetic drive pumps and shielded pumps. In recent years, the reason why it attracts attention is mainly due to the increasing awareness of human environmental protection since the mid-1980s. At present, more and more pump manufacturers recognize the importance of adding a sealless pump in their product line. Obviously, the demand for non-hermetic pumps will continue to grow strongly.

(7) Modularization and modularization of the product The modular pump technology is an important trend in the development of the pump industry. In the modular pump series, only a few parts are required to constitute the entire pump series, which can reduce production costs, shorten delivery time, and reduce the inventory of spare parts and spare parts, while personalized development requires that the products gradually tend to Towards more varieties and small batches.

(8) Material Technology In recent years, the development and application of various new materials have been an important factor in the development of pump technology. Gear pump parts use a variety of new materials, the benefits of which are mainly to extend the life and reliability of the pump in corrosive media, and expand the scope of use of the pump. At the same time, the surface treatment technology of coating technology and materials has become increasingly important in improving the flow characteristics, corrosion resistance, and wear resistance of the pump, and has broad application prospects.
