1. For the high and low temperature alternating damp heat test chamber that has been used for many years, when the silicone rubber is aging, new sealing strips should be replaced in time. 2. When the seal of the door of the test chamber is slightly deformed and the surface is not parallel,...
The sealing system of high and low temperature test chamber generally adopts silicon rubber sealing strip for double heat insulation and airtight tightness. Its function is mainly to seal the door of the test box, prevent outside air from intruding into the test box, prevent the gas in the...
1. Observe whether the refrigeration compressor of the high and low temperature test chamber can be started during the operation of the test chamber, and whether the compressor can be started during the operation of the environmental test equipment, indicating that the circuit from the main power supply to each...
1. constant temperature and humidity test box Calibration under load conditions: The advantage of this method is that it can accurately assess the impact of the sample on the performance of the constant temperature and humidity test chamber, and it is easy to obtain detailed information about the key...
Tensile testing machine is used to test the mechanical properties of various materials such as tearing and stretching. Different materials correspond to different fixtures during the test. The strength and speed of the tensile testing machine are two indicators that need to be paid special attention to...
Constant temperature and humidity test box is also called constant temperature and humidity testing machine, constant temperature machine, etc.; it is used to test the performance of materials in different environments and the materials' heat resistance, cold resistance, dry resistance, and humidity...
1. When the compressor of the high and low temperature test chamber is pressurized for leak testing, the water vapor in the air is compressed into water, which is injected into the pipeline to cause ice blockage. 2. After the refrigeration evaporator is damaged, the water molecules in...
Constant temperature and humidity test chamber, constant temperature machine, constant temperature and humidity chamber, etc., are commonly used to test the performance of materials in different environments and the heat resistance, cold resistance, dryness and humidity resistance of different materials under the...
Tensile testing machine is also called universal material testing machine. It is used to perform static load, tension, compression and other mechanical performance tests on various materials. It can be used to test various physical properties of materials such as plastic sheets, wires and cables. The fixture...
Constant temperature and humidity test chamber, also known as constant temperature and humidity test machine, constant temperature machine or constant temperature and humidity chamber, is used to test the performance of materials in various environments, and test the heat and cold resistance of various materials,...
The high and low temperature test chamber has the function of simulating the law of atmospheric environmental temperature changes. Mainly aimed at the adaptability test of electrical, electronic products and their components and other materials in the process of transportation and use in the high and low...
1. Be sure to replace the gas when the flame appears variegated. 2. Be sure to disconnect the power when replacing the gas. 3. The flame is dark blue when the gas is burning. 4. Keep the test site well ventilated. 5. If the flame jumps...
