YAW300D microcomputer controlled automatic cement pressure testing machine
YAW-300S LCD automatic cement pressure testing machine
1. Scope of application.
This testing machine fully complies with the requirements of national standard GB / T17671-1999, and is mainly used for the compressive strength test of cement mortar. Equipped with appropriate test attachments, it can complete the performance tests of bricks, metal products, components and other materials. Widely used in the building materials industry, it is the ideal test equipment for the building materials industry, technical supervision, commodity inspection and arbitration, scientific research institutes and other departments!
2. Functions and features
(1) The testing machine adopts a double-column frame structure, the upper pressure plate is installed on the upper fixed beam, the lower pressure plate loads the sample upward under the action of the drive screw, and the AC servo control and transmission system are installed on the host Lower part. The testing machine adopts the Japanese AC servo speed control system, which controls the high-precision, high-frequency response AC servo motor, and drives the precision ball screw pair to carry out the test, which can achieve a wide range of test speed adjustment (0.01-50mm / min) Efficient.
(2) The liquid crystal display controller is used to conduct the test according to the requirements of the national standard GB / T17761-1999 "Cement mortar strength inspection method", and the test parameter setting, test process control, data collection, processing, and Analysis and display. Both single piece test and group test can be realized. Control and measurement are precise, accurate, fast, convenient and reliable.
(3) According to user requirements, an external microcomputer can be connected to perform statistics and processing on the test data, and then output and print various required test curves and test reports, which can realize storage, printing and networking functions, intelligent and flexible.
(4) It has the function of returning to the initial position after the test, which is efficient and fast.
(5) It has limit protection function of working position and overload and over-current protection functions, reliable and safe.
(6) Brand computer and printer, quality assurance.
Compared with the old electro-hydraulic servo pressure testing machine, the testing machine has the following advantages
1. The test force measurement range is wider, more accurate, and more stable: due to the zero cover problem of the electro-hydraulic servo control valve during static control (this is an inherent feature of the electro-hydraulic servo valve itself), plus the presence of sealing and friction in the oil cylinder The problem is that the output (displacement and test force) is not linear near zero, and it is easy to crawl at low speed, poor stability, and high initial pressure. It is impossible to achieve output control of small deformation and small test force (short-term sample load is very high Small, can not be achieved by this control method); AC servo motor and ball screw control are adopted, and the above electro-hydraulic servo control problem does not exist, plus the use of high-precision load sensor to measure the force, so the test force measurement range is wider and more accurate ,more stable.
2. Low noise during the test: The noise of the AC servo motor is much lower than the working noise of the hydraulic pump.
3. The control process is not affected by temperature and the performance is more stable.
4. No pollution caused by hydraulic oil running, running, dripping, and leakage.
5. No servo valve is contaminated and stops working
6. The power and transmission system are more compact, the structure is more concise and bright, and the reliability is greatly improved.
7. High reliability for long-term use, maintenance-free (no tedious replacement of hydraulic oil)Liyang Paper Products Co., Ltd. was established in 1999,a professional enterprise integrated in R&D,Marketing and Manufacturing.Liyang Printing provide best solutions and service to various fields of industry.For example,we can make nice and luxury sunglasses boxes for sunglasses packaging.Such as Sunglass Box,Leather Sunglasses Box,Wooden Sunglass Box,Printed Sunglass Box,etc.Our sunglasses boxes with high quality are exquisite packaging for your products.
