The 2020 Asia International Power Transmission and Control Technology Exhibition was held at the Shanghai New International Expo Center. Guangzhou Yutuo Measurement and Control Technology Co., Ltd. brought a newly developed hydraulic pump test bench to the exhibition hall. The hydraulic test bench exhibited this time has beautiful appearance, comprehensive functions, simple and safe operation. The equipment adopts the application of non-welded tubing to ensure the pipeline cleanliness, tightness, and no oil leakage; fully enclosed design, environmental protection and safety; high-precision sensors and meters ensure the accuracy of test data; the principle is more optimized, The test function is more complete. The equipment attracted the attention of many exhibitors at the exhibition, and interested people in the hydraulic industry came to learn about and consult.

Judging the quality of hydraulic components requires hydraulic tests and tests to verify, but hydraulic tests and tests should be treated as part of experimental science, not just as operating a test bench and completing a hydraulic test. Therefore, hydraulic testing and testing must clarify the testing methods of hydraulic components or systems, the measurement of various physical quantities in the test, and the analysis and processing of measurement signals. These are the three main steps for hydraulic testing and testing. Careful completion of these three main steps in hydraulic testing and testing will help achieve the main role of hydraulic testing: mastering the characteristics of hydraulic components, distinguishing the performance of hydraulic products, identifying weak links in hydraulic components, optimizing design and production technology, and thereby Improve product performance. Of course, this also includes how to avoid its weaknesses and make good use of its strengths when a hydraulic component is used in the system. This is usually solved by experimental technology.

The integral hydraulic pump test bench newly developed by our company has been commissioned and officially put on sale yesterday. The hydraulic pump test bench is designed according to the latest test standards promulgated by the country and the hydraulic industry. The hydraulic pump test bench adopts an integral design, which has the advantages of beautiful appearance, strong practicability, high safety factor, and easy operation.

The development characteristics of the global construction machinery industry. 1. The international construction machinery industry has entered a low-speed development stage. The construction machinery industry is closely related to the economy and is greatly affected by the macroeconomic operating situation. The growth rate of the construction machinery industry is much lower than the average level of the machinery industry, and the characteristics of entering a low-speed development stage are obvious. 2. The international construction machinery market and manufacturing pattern are relatively stable. The global construction machinery market is mainly concentrated in North America, Western Europe, China and Japan, these four major markets account for about 70% of the world. A number of emerging construction machinery markets have also begun to rise in recent years, such as Russia and India showing great market potential. The global construction machinery manufacturing is mainly concentrated in the four regions of the United States, Japan, Western Europe and China, and the total output accounts for more than 80% of the world's total. 3. The United States, Japan, Germany and other industrialized countries mainly export construction machinery, while my country's construction machinery is mainly sold domestically. The proportion of European construction machinery exports is about 55%, Japan is about 70%, the United States is about 50%, and my country is about 18%. 4. Digesting inventory has become one of the market focuses of major global companies. In 2013, Caterpillar digested US$2.9 billion in inventory, and Zoomlion reduced its inventory by about 3 billion yuan throughout the year. Digesting inventory has caused many companies to adjust their production plans and future expectations.
