High and low temperature impact test chamber split type

The high and low temperature impact test chamber is also called the thermal shock test chamber, and the thermal shock chamber is divided into two boxes of thermal shock box and three chambers of thermal shock box, and the three-box thermal shock chamber is mainly divided into three parts: high temperature storage tank area, sample test area, low temperature storage tank area, the most used industry is electronic appliances, batteries, auto parts and other products for testing quality. There are few companies in the split high and low temperature impact test chamber industry, at present, only Guangdong Ai Si Li can do, their split high and low temperature impact test chamber is professionally tailored for customers, especially the aisle, elevator and experimental door in the customer factory is too narrow and the equipment is relatively large in size.

The high and low temperature test chamber is used for high temperature and low temperature reliability tests of industrial products. For example, the parts and components of electrician, automobile and motorcycle, aviation and ship, colleges and universities, scientific research units and other related products are tested for various performance indicators under the condition of high temperature and low temperature cycle changes. In addition to the difference between the high and low temperature impact test chamber and the high and low temperature test chamber, there is also a difference in performance conditions, and the high and low temperature impact is reflected in the temperature change rate, and the high and low temperature impact test chamber can achieve high temperature and low temperature rapid conversion in 5-8 seconds.

The high and low temperature impact test chamber can go from high temperature to low temperature and then to high temperature in a short period of time. The high and low temperature test chamber is only adjustable temperature, the temperature change rate is determined according to the heating and cooling rate of the test chamber, the heating rate is generally 1 3 minutes, the cooling rate is generally minutes, and the temperature conversion takes a long time. The high and low temperature impact test chamber and the high and low temperature test chamber are also very different due to the different working methods and box structures, and the production costs are also different.

We can! We are a professional manufacturer of environmental test equipment, in addition to the production of environmental test equipment, we have rich experience in the design of non-standard environmental test chambers; Regarding the split high and low temperature impact test chamber you mentioned, there are generally two situations that need to change the integrated high and low temperature impact test chamber to a split type, one is that the external dimensions are too large, which is inconvenient to transport or enter a specific space; Second, the specimen is not allowed to have strong vibration, no matter what the reason, you need to provide specific requirements, so that the targeted design can be carried out according to the requirements.

So! If there is a need, you can us.

The high and low temperature impact test chamber is also called the cold and hot shock test chamber and the temperature shock test chamber. Why do you want to do the component type, this is because the customer needs to test the product with such a large volume size for the test, but the elevator or the door to the laboratory is fixed and difficult to change, so our company will customize the component type according to the customer's requirements.

The purpose of high and low temperature impact test chamber and high and low temperature damp heat test chamber is basically the same, high and low temperature alternating damp heat test chamber is the environment of temperature change and alternating damp heat, and high and low temperature damp heat test chamber is an environment with constant temperature change and humidity. The structure of the two is basically similar - Shanghai Guangpin provides you with it.

High and low temperature impact test.

There is not much difference between the chamber and the high and low temperature damp heat test chamber, and it is suitable for high temperature resistance, low temperature resistance, damp heat resistance and cold and thermal shock test tests.

The main function of the high and low temperature impact test chamber is to do the cold and hot shock test of the product, such as the impact test of -40 degrees and 100 degrees, and the temperature change time is less than 5 minutes. That is to say, the product is tested in an environment of -40 degrees Celsius for many hours, and then transferred to a high temperature of 100 degrees Celsius within 5 minutes.

The high and low temperature damp heat test chamber can not do such a test, and the high and low temperature damp heat test chamber can do a separate low temperature, high temperature, and damp heat test, and the temperature change is a gradual time process

First, the sample is placed under normal test atmospheric conditions until its temperature becomes stable.

2. Compare with the standard requirements, and put the samples that meet the requirements directly into the high and low temperature impact test chamber.

3. Start experimenting:

1. Put the test sample into the high and low temperature impact test chamber according to the standard requirements, and at the same time raise the temperature in the test chamber to the specified temperature, and then keep the temperature of the sample stable for a period of time.

2. After the test in the high temperature stage, convert the sample to your customized low temperature test chamber within 5 minutes, and hold it for another 1 hour or more until the temperature of the sample reaches a stable temperature.

3. After the low temperature stage of the test is over, convert the sample to your customized high temperature test chamber within 5 minutes, and keep it for another 1 hour or more until the temperature of the sample reaches stability.

4. Repeat the above test methods three times to complete the cycle cycle, according to the size of the sample and space, there may be some errors in time.

5. When the sample is taken out of the test chamber, it needs to be recovered for a certain period of time under normal test atmospheric conditions until the temperature of the sample reaches stability.

6. Finally, the degree of damage in the standard is compared to evaluate the test results.

The structure and control instruments of the high and low temperature impact test chambers produced by different manufacturers are different, so please refer to the random operation instructions for specific operation and use; In addition to the detailed operation, let's talk about some precautions when using it:

1. If it is an air-cooled high and low temperature impact test chamber, it should be ensured that there are sufficient ventilation and heat dissipation conditions around the box, which is recommended to be above 50cm, and the ambient temperature is not high at 35 degrees Celsius, and there is no direct sunlight. The water-cooled high and low temperature impact test chamber pays attention to whether the water supply temperature and quantity meet the requirements of the high and low temperature impact test chamber, and it is absolutely forbidden to use it if it does not meet it.

2. The drain valve at the rear of the equipment box must be opened, and the high and low temperature impact test chamber will automatically have a defrosting action after working for a certain time, and the condensate generated by defrosting needs to be discharged out of the box in time.

3. Regardless of the three-box high and low temperature impact test chamber or the two-box high and low temperature impact test chamber, when placing the specimen, please be sure to follow the test piece volume shall not be greater than 1 3 of the studio volume, the cross-sectional area shall not be greater than 1 2 of the working cross-sectional area, the maximum size of the specimen shall be more than 10cm from the wall of the studio, and the two-box high and low temperature impact test chamber must pay attention to the specimen not to protrude outside the hanging rail, and it is not easy to slip down.

4. At the end of the test, if the last step is low temperature, under the premise that the test conditions allow, be sure to set the function back to normal temperature to avoid frost on the surface when the test piece is taken out.

5. It is absolutely forbidden to use the high and low temperature impact test chamber for testing, and do not have any luck mentality, because the high and low temperature impact test chamber has no relevant protection design, and forced use may be a safety risk.
