1、 Functions and features:

1. Compressive and flexural strength testing machine is mainly used to test the compressive and flexural strength of cement, mortar, concrete, aerated concrete, gypsum, Amoy sand and so on, which fully meets the requirements of national standards

2. The testing machine adopts a double column frame structure, the upper pressure plate is installed on the upper fixed beam, and the lower pressure plate loads the sample upward under the action of the driving screw, which is controlled by AC servo

In the lower part of the main engine. The testing machine adopts Taiwan Dongyuan AC servo speed control system to control high-precision, high-frequency response AC servo motor and drive precision ball screw pair for testing

The test process was stable and efficient.

3. LCD controller is used to test according to the national standard, and independently complete the setting of test parameters, control of test process, data acquisition, processing and analysis

The control and measurement are precise, accurate, fast, convenient and reliable.

4. According to the requirements of customers, PC can be connected to count and process the test data, and then output and print the required test curves and test reports, which can be stored and printed

Ability and flexibility.

5. It has the function of returning to the initial position after the test, which is efficient and fast.

6. It has limit protection function of working position, overload and over-current protection function, which is reliable and safe.

Compared with the old electro-hydraulic servo pressure testing machine, this testing machine has the following advantages

a: The test force measurement range is wider, more accurate and more stable: because of the zero position covering problem of the electro-hydraulic servo control valve in static control (this is the inherent characteristic of the electro-hydraulic servo valve itself)

Because of the problems of sealing and friction, the output (displacement and test force) near the zero position is not linear, and it is easy to crawl at low speed, with poor stability and high initial pressure, so it is unable to achieve small deformation and small deformation

The sample load is very small, which can not be controlled by this way; AC servo motor with ball screw control, there is no problem of the above electro-hydraulic servo control, plus the use of AC servo motor

Therefore, the test force measurement range is wider, more accurate and more stable.

b: Low noise during the test: the noise of AC servo motor is much lower than that of hydraulic pump.

c: The control process is not affected by temperature and the performance is more stable.

d: No pollution caused by hydraulic oil running, emitting, dripping and leaking.

e: No servo valve stopped working due to contamination.

f: The power and transmission system is more compact, the structure is more concise and bright, and the reliability is greatly improved.

g: Long term use, high reliability, maintenance free (no trouble of changing hydraulic oil).
