WAW-L series microcomputer controlled electro-hydraulic servo single pull testing machine

Main purpose

It is our company's new generation electro-hydraulic servo tensile testing machine product. This machine adopts a four-column single-pull frame structure, which realizes the rapid rise and fall of the two-way cylinder in one space to adjust the test space and fully automatic control of tension and compression in both directions. The high-precision test force and strain sensor have the characteristics of one resolution without step-by-step throughout the entire process.The main components are imported products to ensure their service life and testing accuracy.

Function introduction

1. It has three closed-loop functions, that is, it can control stress, strain, closed-loop and other control methods, and can switch without impact. Its stress speed and strain rate fully comply with the requirements of other tensile test standards such as the national standard GB228-2002.

2. Adopt the fully digital multi-access closed-loop measurement and control system developed by Shandong Huayan Intelligent Equipment Group Co., Ltd. (or use the German DOLL company EDC-220 according to user requirements).

3. The tensile bidirectional flange load sensor is used, which has the ability to resist eccentric load, high measurement accuracy, and good linearity. It avoids many disadvantages caused by using oil pressure sensors and affects the accuracy of force value measurement.

4. The high-performance two-way oil cylinder adopts original imported seals, which has good sealing performance and no oil leakage. The unique pressure follow-up technology of the follow-up valve can ensure that the system pressure is always only 2Mpa higher than the required pressure value of the oil cylinder, which greatly saves energy and heat.

5. The use of Hydac company's filters ensures the cleanliness of the hydraulic system oil, and ensures reliable system operation and long service life.

6. Using high-pressure internal gear and gear pump (patented two-piece eccentric gap filling and radial and axial pressure compensation design, high efficiency, low pressure pulsation, stable pressure) and shock absorption and sound insulation design make the noise less than 50dB

7. Windows Chinese version real-time control experiment software, automatically collects and processes test data, displays test data, load-deformation curve, load-time curve in real time, and can print experimental reports in the format required by the user.The original data of the tensile process is automatically saved in the default folder, and the tensile curve can be reproduced and the test results can be reanalyzed.The computer can export the original data of the experimental process, use Excel and other tools to reproduce the tensile curve and check various data.

8. The testing machine complies with the requirements of standards GB/T2611-92 "General Technical Requirements for Testing Machines" and GB/T16826-1997 "Electro-hydraulic Universal Testing Machine".

9. The software reserves a data interface to facilitate local area networking between laboratories and test data management.
