With the continuous vigorous development of science and technology, the rapid progress has injected new vitality into the environmental testing chamber industry,thermal shock chamberIt has penetrated into every different industry and every field. From daily life to our work. The thermal shock test chamber has great potential for development.
The appearance of the cold and hot shock test box product is beautiful, the structure is reasonable, the technology is advanced, and the material selection is exquisite. It has simple and convenient operation performance and reliable equipment performance. Secondly, the internal structure of the product. The LCD screen three box cold and hot shock test box is composed of a low high temperature zone, a low temperature zone, and a testing zone.
The working principle of this device is to drive it into the testing area through a high-pressure cylinder for temperature shock. The testing method is static, and the shock method is to use the air path switching method to cool down and introduce it into the testing area for cold and hot testing. The testing area forms a closed-loop air circulation system with either a high-temperature box or a low-temperature box, quickly reaching the target temperature for the experiment. The temperature state inside the test chamber is determined by the working status of the heater, evaporator, and fan in the air duct. The cold and hot shock test chamber adopts a forced axial flow "dispersion" loop air working method in the working room, which can greatly improve the fluctuation and uniformity of equipment operation.
The cold and hot shock test chamber is a commonly used experimental equipment, suitable for testing material structures or composite materials, and is a reliable device for environmental testing that can withstand continuous temperature and extremely low temperatures in an instant. It has the advantages of smooth operation, high reliability, easy maintenance, and wide applicability, and has been widely used in multiple fields.
The thermal shock test chamber is a testing equipment used in the metal, plastic, electronics, rubber and other material industries to inspect composite materials and material structures. It can withstand a continuous environment of mild and extremely low temperatures in an instant to detect physical damage and chemical changes caused by thermal expansion and contraction of the sample in a short period of time. Today, let's talk about three key points to pay attention to when measuring this device.
Measurement characteristics:
1. Deviation: The deviation between the measured high and low values of each measuring point in the workspace and the nominal value when the equipment is in a stable state;
2. Uniformity: The difference between each testing point (temperature and humidity) in the workspace at a certain moment when the environmental testing equipment is in a stable state;
3. Volatility: The change in the center point parameter of the workspace over time when the environmental testing equipment is in a stable state.
Measurement method:
1. Measurement is carried out under no-load conditions. If there is a load, the load situation should be stated in the certificate.
2. The measurement of turbidity and humidity points should generally choose the upper limit, lower limit, and center point of the equipment's usage range, or actual commonly used temperature and humidity points can be selected according to user needs.
Location of measuring points:
1. When the volume of the environmental testing chamber is greater than 2m3, there are fifteen temperature points and four humidity points.
2. When the working volume of the environmental testing chamber is less than 2m3, there are nine temperature points and three humidity points.
