Lightweight, modular pump technology trends

Energy Saving and Emission Reduction Need Technological Innovation

With the continuous advancement of technology, lightweight, modular technology innovation into the pump industry has become a trend. The pump products are bound to develop in the direction of intelligence. They can monitor parameters such as pressure, flow, temperature and vibration; they can evaluate the shaft, bearing and sealing conditions of the pump; and can diagnose the cause of the failure. The technical development of the magnetic pump and diaphragm pump industry will be concentrated in designing electronic regulating systems, improving drive devices and seeking new materials.

Scientific and design methods are necessary. Therefore, we must strengthen the basic theoretical research of the pump and pay attention to the mutual penetration 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.

The high technology of production and manufacturing is the fundamental guarantee for the low price and high quality of products. 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.

Modular pump technology is an important trend in the development of pump technology. In the modular pump series, only a few parts are needed to constitute the entire pump series, which can reduce production costs, shorten delivery time, and reduce parts and inventory, while personalized development requires the product to gradually In the direction of more varieties and small batches.

In recent years, the development and application of various new materials is an important factor in promoting the development of pump technology. Pumps use a wide variety of new materials. The main benefits are the extended pump life and reliability in corrosive media and the extension of the pump's range of use. At the same time, the surface treatment technology of coating technology and materials has become increasingly important in improving the flow characteristics and corrosion resistance of the pump, and has broad application prospects.

Traditional manufacturing and information technology

Into the information age today, pump designers have already used computer technology for product development and design (such as the use of CAD), greatly improving the speed of the design itself and shortening the product design cycle. In manufacturing-oriented manufacturing, manufacturing technology represented by numerical control technology CAM has penetrated into the production of pumps. However, judging from the recent domestic situation, CNC CAM is mainly used in the production of batch products. For the single-piece or small-batch production, the current CAM technology has not yet been universally implemented in the pump industry. The production of small batches of single-pieces is still based on traditional production equipment.

As the market requires the manufacturer's delivery time to be as short as possible, especially for the special products (products for the user's requirements), the supply period is shortened, and the pump manufacturer is bound to require the pump manufacturer to accelerate the use of CAM technology or even computer integrated manufacturing system (CIMS) and flexibility. Manufacturing (FMC and FMS) co-ordinates all aspects from design to manufacturing molds, parts processing, etc. to ensure that once the design is completed, the processing of product parts tends to be completed in the same period to ensure that the product's production cycle is shortened.

At the same time, besides using computer graphics, it will also realize product strength analysis, reliability prediction, and three-dimensional design on the carrier of the computer. It will involve the process problems, local structural problems, and assembly that were originally required to be discovered and solved in production. Issues and other aspects were raised before production and precautions were taken to shorten the product trial period.

At the same time as the diversification of products, pumps as general products, the overall total volume is still huge. In the market, in addition to technical competition, price competition of products, especially general-purpose products, is an inevitable trend. In the trend of diversification of products, it is necessary to realize the competitive advantage of product prices, improve the standardization of product components, and realize the modularization of product components. After the modularization of many parts and components, through the combination of different modules or changing the characteristics of individual parts, in order to achieve product diversification. At the same time, it is only when the degree of standardization of parts and components is improved that it is possible to base on the diversification of products to actualize the production of parts and components in order to reduce the production costs of products and to form the price competitive advantage of the products, and it is also possible to diversify the products. On the basis of further shortening the product delivery cycle.
