1. Name of the goods: High and low temperature low pressure test chamber (simulated height test machine)

Description of high and low temperature low pressure test chamber and steps of use

Second, the name of the manufacturer: Beijing Yashilin Test Equipment Co., Ltd. 3. High and low temperature low pressure test chamber (simulated height test machine) 4 test procedures:

a: storage / air transport, procedures b: work / off-board flight, procedures c: rapid decompression and procedures, procedures d: explosion decompression, according to the requirements of the relevant documents, confirm the test procedures or test procedures.

4. Select the factors to be considered in the test procedure. The selected procedure should be representative of the most severe low-pressure environment expected to be exposed by the equipment. Consideration should also be given to the selection of test procedures:

a, the technical status of the equipment;
b, the work requirements of the equipment;
c, the use of equipment;
d. Data required to determine whether the equipment meets the work requirements;
e. Test procedure sequence.

5. Differences between the procedures of the high and low temperature low pressure test chamber (simulated height test machine):

Procedure 1: Storage/Air Transport: Equipment suitable for transport or storage at high altitudes, or equipment transported by air under transport/storage technology, to determine if Procedure 1 is applicable based on low air pressure effects and life cycle environmental profile.
Procedure 2: Work/External Flight: Applicable to determine the performance of the equipment under low air pressure conditions, before Procedure 1 and Procedure 2. If there is no requirement for low pressure storage, rapid decompression or explosion decompression, Program 2 can be used separately. get on.
Procedure 3: Rapid Decompression: Procedure 3 applies to high-frequency infrared carbon and sulfur analyzers to determine whether rapid reductions in ambient pressure around the equipment can cause equipment to react, harm surrounding personnel or damage the platform of the transport device, and Program 3 can be stored or worked. After the test.
Procedure 4: Explosive decompression: Procedure 4 is the same as Program 3 except that the decompression rate is faster than Program 3.

Sixth, high and low temperature low pressure test chamber operation steps:

1. Connect the test sample to the wire and place it in the box.
2. Connect the suction line.
3. Close the door and open the vacuum pump to start pumping.
4. When the air pressure reaches the test atmospheric pressure, close the suction valve.
5. Allow the air pressure to remain in the test for the specified time.
6. Open the intake valve and return the air pressure to the normal value.
7. Open the door and take out the test sample.
