What do you need to know before purchasing the high and low temperature chamber

Precautions when purchasing the high and low temperature test chamber:
1. Before understanding the high and low temperature chamber, we should first understand the needs of our own enterprises, understand the various performance parameters of the products to be tested, such as size, temperature range, price budget, etc., narrow the screening range, and purchase the appropriate products.

2. Pay attention to the material of the chamber: due to the particularity of the equipment, it is necessary to select materials that are resistant to high temperature/low temperature and free of pollutants, and can not interfere with the test items and affect the test results.

Therefore, high strength materials with good stability and environmental protection are generally selected, such as stainless steel. The material and thickness of the insulation layer are also important factors to be considered.

Generally, heat-resistant and flame-retardant materials are selected with sufficient thickness to ensure that the temperature of the outer wall of the chamber will not be too high or too low during operation. It is better to have a shelf for the test sample in the test chamber. The shelf shall also have the characteristics of corrosion resistance, oxidation resistance and high and low temperature resistance.

3. When selecting, it is necessary to select the chamber with good sealing performance, especially the chamber door, which must be equipped with sealing strips with good thermal insulation effect around. In addition, during the test, the temperature in the chamber must be uniform and constant to ensure that the temperature of each part of the test sample is the same.

4. In order to make the test operation more convenient and safe, the high and low temperature chamber also need to be equipped with observation windows, lights, safety protection and alarm devices, which can record synchronously and display various data during the test.

Several key points in the purchase of high temperature test chamber:
1. The temperature control sensitivity of the high temperature test chamber is high, and the temperature in the chamber can be well controlled by the separately designed circulating air duct. The unique design of the circulating air duct makes the hot air generated in the operation of the equipment circulate at the air outlet and the return air outlet, thus dispersing the hot air and ensuring the uniformity of the temperature in the chamber.

2. The test equipment adopts high-quality temperature controller, with more accurate data, stronger temperature adaptability and bearing capacity. Compared with the old test equipment that can only withstand 150 ℃ – 200 ℃, the high temperature test equipment that can operate normally at 300 ℃ or even higher temperature is more widely used.

The equipment also has the functions of leakage protection, overtemperature alarm, overtemperature protection, etc., which is more secure and more convenient for users to operate. In addition, compared with other equipment, the outer chamber is more beautiful and novel because of its electrostatic spraying.

Answering questions and solving problems in high and low temperature test chamber:
Q1. Why is it difficult to open the high and low temperature test chamber?
A1: This may be because the wet air enters the irregular hole on the contact surface between the door and the door pocket, and forms a negative pressure when the door is closed. The sealing magnetic force and the pollution relay will cause mixing and attraction, and it will be more difficult to open it later. In this case, the door seal can be cleaned with soap water to ensure elasticity and smoothness, and talcum powder can be applied to eliminate condensation.

Q2. What noise does the test chamber equipment sometimes make?
A2: The fixing screws and nuts of the compressor in the high and low temperature test chamber are loose, or the water connection plate of the equipment is loose; When more refrigerant oil enters the evaporator of the equipment, it will also make a gurgling bubble sound; In addition, due to cylinder falling off, compressor spring loosening, serious wear of internal parts, poor lubrication and other reasons.

The pipeline vibration is due to the long suspension of the pipeline, which is more prone to the same vibration phenomenon, and the noise is significantly increased, showing periodic fluctuations. When pressing in a part that is more prone to vibration, the noise will be significantly reduced or eliminated when pressing in a part.

According to different situations, adopt methods and measures such as cushioning, reinforcement and isolation, such as damping mortar, rubber sleeve, etc. Poor vacuum evacuation of the equipment may also cause grunt, which may also be caused by equipment failure. The operator can investigate and deal with it one by one.

Q3. Can the high and low temperature test chamber be used again after being placed for a long time?
A3: In order to place the test equipment for a long time, it is necessary to do a good job of cleaning to ensure that the components are intact, the equipment testing machine and the equipment can operate normally, and the test work can be carried out.
