Product Description

 

Product Description

 

The machine uses compressor mechanical refrigeration to provide a constant low temperature environment, and can heat up according to the set temperature rise rate. The cooling medium is alcohol (prepared by the customer). The special stretching fixture and displacement sensor of the machine are used to measure the temperature value of rubber and other materials when the deformation reaches the specified value with the gradual increase of temperature after being frozen at low temperature for a period of time. This machine adopts computer system integrated control, software one-key test, automatic calculation and other related parameters.
Executive standard:
GB/T7758, ISO 2921, etc.
Features:
It adopts computer system integrated control and PLC programmable controller integrated control, which is easy to operate, integrated control, automatic timing, and real-time display of temperature. Program automatic control.
Adopt high-precision special temperature control module, PID intelligent temperature control. Heating rate can be set
Using a high-precision displacement sensor, the displacement resolution accuracy can reach 0.01mm. The measurement range is wide.
The stepper motor and driver are used as the power source to initially load the deformation of the sample. After reaching the deformation, when the sample is immersed in a low-temperature environment, the motor returns quickly to ensure that the sample is in a free relaxation state.
The upper clamp has a corresponding counterweight device, which can keep the sample at a slight tension (10KPa ~ 20KPa), and at the same time lock the upper clamp at the position of the selected elongation. After the sample invades the low temperature tank, the fixing device will be opened automatically .
The sliding part of the sample holder is made of low-friction and very thin material, which is basically suspended, with small contact surface, smooth operation and low friction. The conversion of the sample rack between low temperature and normal temperature adopts pneumatic control. fast and convenient.
Temperature uniform mixing system, equipped with electric motor and stirring fan, ensures temperature uniformity.
The surface of the evaporator is treated with  and other processes, which has good corrosion resistance
Ethanol (prepared by the customer) is used as the heat conduction medium, and the temperature uniformity is good.
It adopts French Taikang two-stage hermetic compressor, air-cooled. Advanced multi-channel, environmental protection and energy saving (low noise) mechanical compression refrigeration system. R404A and R23 environmentally friendly refrigerants can quickly cool down to -70°C.
