Description |
| Air conditioning method |
Forced ventilation internal circulation, balanced temperature control method (BTCH). In this method, when the refrigeration system is continuously working, the central control system performs amplification, analog/digital conversion, nonlinear correction and temperature adjustment based on the collected temperature and humidity signals in the box. Compare them with the humidity set value (target value), and the resulting deviation signal is calculated by PID to output an adjustment signal, automatically controlling the output power of the heater, and finally making the temperature in the box reach a dynamic balance. |
| Air circulation device |
Air circulation device: Built-in air-conditioning room, circulating air duct and long-axis centrifugal fan, using efficient refrigerator and energy regulation system, effective heat exchange through efficient fan to achieve the purpose of temperature change. By improving the air blast flow, the air flow rate and the heat exchange capacity between the heater surface and the air are increased. Through the adjustment of the air outlet, the temperature uniformity of the test chamber is greatly improved. |

Description |
| Refrigeration Compressors |
The refrigeration system is composed of "French Tecum" compressor. Compared with similar types of refrigeration compressors, this type of compressor has large cooling capacity, low noise, low energy consumption and high efficiency. Able to operate stably and reliably for a long time. It greatly reduces the user's usage costs, helps reduce the noise of the equipment, prolongs the service life of the equipment, and improves the economy of equipment use. |
| Refrigeration principle |
Both the high and low refrigeration cycles adopt the reverse Karo cycle, which consists of an isothermal process and an adiabatic process. The process is as follows: the refrigerant is adiabatically compressed to a higher pressure by the compressor, and work is consumed to increase the exhaust temperature. The refrigerant exchanges heat isothermally with the surrounding medium through the condenser and transfers heat to the surrounding medium. After the refrigerant passes through the shut-off valve, the adiabatic expansion does work, and the temperature of the refrigerant decreases. Finally, the refrigerant absorbs heat isothermally from the higher temperature object through the evaporator, causing the temperature of the object to be cooled to decrease. This cycle repeats itself to achieve the purpose of cooling. |

This series of electronic universal testing machines is a classic and practical model developed by our company, and it is also the mainstream model currently produced. Our company learned from Japanese technology and based on previous generations of models, it has been designed and developed through many new upgrades. The host structure and measurement and control system have been significantly upgraded technologically, with a more reasonable structure and more complete functions. It is the leading technology in the industry. A new generation of electronic universal testing machine. More than 1,000 units of this series of testing machines have been produced. After a large number of practical tests and continuous improvement, the technology and process are mature, high reliability and low failure rate, and are well received and welcomed by the market and users.
The testing machine adopts Japan's Panasonic digital AC servo speed regulating system and servo motor with high speed control accuracy and stable performance as the driving system. The specially designed synchronous toothed belt deceleration system and ball screw pair drive the moving beam movement of the testing machine. The control and data processing software based on database technology, which uses Windows as the operating platform, realizes the screen display of test force, test force peak value, beam displacement, specimen deformation and test curve. All test operations can be performed on the computer screen with the mouse. The input method is completed, with a good human-machine interface and easy operation. The independent dual-channel fully digital programmable amplifier realizes automatic shifting, zeroing and calibration of physical zeroing, gain adjustment and test force measurement in a true sense without any analog adjustment links. The control circuit is highly integrated and the potential is completely eliminated. Mechanical adjustment devices such as regulators have simple structure and reliable performance. It ensures that the machine can achieve closed-loop control of parameters such as test force, specimen deformation and beam displacement, and can realize tests such as constant force, constant displacement, constant strain, constant rate load cycle, and constant rate deformation cycle. Users can use the PC expert system to independently set control modes such as constant stress, constant strain, and constant displacement, and can switch between various control modes smoothly and without interruption. It can realize data processing that complies with various standards such as GB, ISO, JIS, ASTM, DIN and so on. It has good scalability in particular. The processing results can be stored on disk in the form of ASCII code, which is useful for re-analysis of test data, database management, Post-processing such as network transmission provides convenience.
This series of electronic universal testing machines are powerful and widely used. It can be used to test mechanical properties such as tension, compression, bending, shearing, peeling, tearing, extraction, and ring stiffness of various metals, non-metals and composite materials. It is suitable for metal wires, metal foils, metal plates and metal Mechanics of metal materials such as rods and plastic pipes, plastic profiles, waterproof membranes, geotextiles, wires and cables, textiles, fibers, rubber, ceramics, concrete, adhesives, food and medical packaging, films, wood, paper and other non-metallic materials Testing can be widely used in manufacturing enterprises such as machinery manufacturing, vehicle manufacturing, aerospace, petrochemicals, wires and cables, papermaking, textiles, construction and building materials, and in quality supervision and inspection departments, scientific research institutes and other research departments, as well as universities and technical schools Schools conduct teaching and demonstrations.
For non-metallic material testing, the large test space, wide speed range, and various attachment configurations can meet the testing needs of various non-metallic materials.
A variety of optional test accessories and test standards can meet the testing of different materials and achieve the effect of one machine with multiple uses.
