Gear Pump Industry Technology Development Trend Analysis

With the continuous progress of technology, gear pump products will progress to the direction of intelligence, to monitor the pressure, flow, temperature and vibration parameters: to evaluate the pump shaft, bearing and seal condition: to diagnose the cause of failure. The technical progress of the pump industry will focus on the design of electronic adjustment systems, improvingthe driving device and seek ing new materials.

(1) Progress Towards the Integration of Machine,Electricity and Instrument

Gear pump products whether small household pump, construction pump and other general pump, or large petrochemical, electric power and other industrial equipment with the process pump, are in the direction of machine, electricity, instrument integration progress, make pump products more efficient, energy saving, more convenient use and maintenance, improve reliability, prolong life, for users to bring greater benefits.

(2) To the Direction of Large-Scale and High-Speed Development

With the development of large-scale and large- scale power stations, stone equipment and water conservancy projects, pump as

its supporting products must be in the direction of large-scale and high-speed development.

(3) To the Direction of Multi-Species and Multi-Use Progress

In order to satisfy the needs of different working conditions and uses, pump products are bound to expand the variety specifications, expand the performance range direction progress. At present, the domestic pump products in specifications, varieties and wide use of the aspects still need to be further improved. For example, for high pressure small flow pumps, mixed acid pumps and highly corrosive chemical slurry pumps, also need to constantly develop new varieties.

(4) Scientific Theory and Design Method

Strengthen the basic theory discussion of pump, pay attention to the interpenetration of cross disciplines, marginal disciplines andemer ging disciplines. The key points of theoretical discussion are: measurement, numerical simulation and performance prediction of pump internal flow; Numerical calculation of unary viscous flow; Theory and application of multiphase flow; Pump optimization design and design diversification.

(5) The Progress of CAD, CAM and CIMS Technology and Its Application

The high technology of production and manufacturing is the fundamental guarantee of "cheap and fine" products. Through the use of advanced computer-aided design and computer-aided manufacturing technology, not only ensure the design quality   of products, but also shorten the design cycle, greatly improve the strength of product design, to achieve the optimization of the design scheme, to ensure the reliability of products. 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 guaranteed the performance of the products.

(6) No Seal Pump Technology

Non-sealed pump mainly includes magnetic drive pump and shield pump. In recent years, it has attracted attention mainly because of the increasing awareness of environmental protection since the mid-1980s. At present, more and more pump manufacturers are familiar with the need to add a non-sealed pump to their product line. Obviously, the demand for non-sealed pump will continue to grow strong momentum.

(7) Product Modularization and Individuation

Modular pump technology is an important trend of pump technology development. In the modular pump series, only a few parts can constitute the whole pump series, so as to reduce the production cost, shorten the delivery time, reduce the inventory of parts and spare parts, and the progress of the commonality requires that the product gradually tends to the direction of many varieties, small batch progress.

(8) Material Technology

In recent years, the development and application of various new materials is an important factor to promote the development of pump technology. Gear pump parts adopted a variety of new materials, the benefits are mainly to extend the pump in corrosive medium service life and reliability, and expand the scope of use of the pump. At the same time, coating technology and material surface treatment technology are becoming increasingly important in improving the flow characteristics of the pump, corrosion resistance and wear resistance, and have broad application prospects.
