Railway signal equipment sand and dust test box

- Railroad Signal System: Used to test the dustproof performance and signal transmission performance of railroad signal equipment in sand and dust environment.

- Railroad Infrastructure: Used to test the signal lamps, track circuit equipment, control systems, etc. along the railroad line.

- Quality inspection organizations: Quality inspection organizations are used to test the sand and dust performance of railroad signaling equipment to ensure that it meets the relevant standards.

- R&D department: The R&D department is used to test the sand and dust performance of newly designed railroad signaling equipment and evaluate its protection capability.

FAQ 1: What is a railroad signaling equipment sand and dust test chamber?

Answer:Railway signaling equipment sand and dust test chamber is a kind of equipment specially designed to simulate the sand and dust environment that railroad signaling equipment may encounter in actual operation, in order to evaluate its protection performance, durability and reliability. It simulates a dusty environment by generating and controlling the dust concentration, airflow speed and other parameters to ensure the normal operation of the equipment under adverse conditions.

FAQ 2: What types of railroad signaling equipment is the chamber suitable for?

Answer: The test chamber is applicable to various types of railroad signaling equipment, including signal lamps, track circuit equipment, signal control system, railroad communication equipment, turnout control equipment and so on. These equipments are easily affected by sand and dust along the railroad lines and in tunnels and other environments.

FAQ 3: How does the test chamber simulate the sand and dust environment?

Answer:The test chamber generates sand and dust through the sand and dust generator, and utilizes an airflow system to evenly distribute the sand and dust inside the test chamber. The dust concentration and airflow rate can be adjusted according to the test standard or customer requirements to simulate different dust environments, such as deserts, railroad construction sites, and so on.

FAQ 4: What are the test standards of the test chamber?

Answer:The main test standards include IEC 60529 (enclosure protection level), GB/T 2423.37 (Chinese National Standard), ISO 12103-1 (Road Vehicle Standard), EN 50125-3 (European Railway Standard), and IEC 62236-3-1 (Railway Electromagnetic Compatibility Standard). These standards define specific methods and requirements for sand and dust testing.

FAQ 5: What is the test procedure of the test chamber?

Answer:The test procedure includes:1) Initial inspection: Appearance and function inspection of the equipment under standard environmental conditions.2) Sample placement: Place the equipment in the test chamber.3) Setting parameters: Set the parameters such as dust concentration, airflow rate, etc. according to the standard or customer's requirements.4) Starting the test: Start the chamber to conduct the test.5) Continuous monitoring: Regularly monitor the status of the equipment and record the data.6) End of test: Remove the equipment for appearance and function inspection.7) Test procedure: Remove the equipment for appearance and function inspection.8) Test procedure: Remove the equipment for appearance and function inspection. Remove the equipment for appearance and function checking.

FAQ 6: How to evaluate the test results?

A: The evaluation criteria include appearance inspection, function test, sealing test, electrical performance test, mechanical performance test and signal transmission test. After the test, you need to check whether there is any sand and dust deposition on the surface of the equipment, whether there is any sand and dust entry in the sealing part, and evaluate whether its functions are normal or not.
