HZAOC AK-RJX-9S horizontal Mechanical Properties Testing Machine

Applications

The product is suitable for the performance test of insulator materials under high-low temperature environmental conditions for cooling and heating cycles and tensile load application at the same time.

Cabinet structure

1. The structure of the box is customized according to the size of the specimen. 

2. The inside of the box is made of 1.0mm imported SUS304B stainless steel plate, the outer side is sprayed with 1.0mm cold-rolled steel plate, and the insulation material is made of ultra-fine glass insulation cotton.

3. The door seal is made of double-layer silicone rubber sealing material.

4. An air conditioning cabinet is set up in the box studio, and evaporators, electric heaters, fans, fan volutes and other equipment are installed in the middle of it.

5. The temperature sensor is placed at the air outlet.

6. The air supply mode in the Test Chamber is the upper air supply and lower return air mode.

Mechanical performance load system

It is equipped with a mechanical properties tensile device, and the insulator element bears four 24-hour cooling and heating cycles at the same time, and applies a tensile load, and the size of the load is kept between 60% ~ 65% of the specified electromechanical or mechanical damage load.

Heating and cooling systems

1. The heater adopts porcelain frame nickel-chromium wire electric heater, which has low thermal inertia and long life. The controllable pulse duty cycle PID signal is output by the instrument, which is controlled by a solid-state relay, and the control is stable and reliable.

2. Low-temperature refrigeration adopts French "Taikang" fully enclosed compressor unit. OTHER REFRIGERATION COMPONENTS SUCH AS THE UNITED STATES RANCO, SPORLAN, SWITZERLAND "ALFALAVAL", DENMARK DANFOSS, ITALY CASTEL, JAPAN SAGINOMIYA AND OTHER ORIGINAL IMPORTED PRODUCTS. R404A environmentally friendly refrigerant is used.

3. In order to ensure the safe operation of the system, it is necessary to set up high-low Voltage control, overpressure, overload and other protection systems in the system. At the same time, in order to monitor the operation of the system, high-low Voltage gauges need to be installed at both the high-low Voltage ends to monitor the operation of the system.

4. The refrigeration capacity is adjusted by the shunt method.

Control system

1. Temperature controller: 7-inch large-screen true-color LCD touch screen temperature controller, accurate and stable control, long-term operation without drifting.

2. Sensor: PT100 temperature sensor.

3. The control heating output is triggered by solid-state relay zero-crossing to reduce noise, reduce pollution, facilitate maintenance, and improve control accuracy.

4. Safety protection measures should be set in the control system, including: phase loss protection, phase sequence error protection, phase Voltage uneven protection, fan overload protection, overtemperature, power-off protection, unit high-Voltage protection, unit overload protection, unit overtemperature protection, leakage and other protection.

5. The control system is equipped with a user-friendly operation panel, equipped with power supply, lighting, operation buttons for various functions and fault indicators.

6. In addition to the main controller in the system, an independent over-temperature protector is also set up, even if the main controller fails, the over-temperature protector can reliably disconnect the heating power supply to protect the safety of equipment and samples.

7. There is an interlock device in the electrical control system, when the circulating fan is not started or overloaded, the refrigeration unit and the heating system can not be started, and the refrigeration unit will be prohibited when the unit is overloaded and overloaded.
