Baijian Testing is mainly engaged in textile, insulation, cosmetics, food, hardware industry related product testing, as well as providing product certification services, but also in the broadening of the scope of the testing industry, the laboratory issued a report can be stamped CNAS/CMA/CAL qualification seal, the report is true and effective.

Testing process

1, sending samples

2, checking requirements

3, targeted quotation

4, both parties determine, sign a contract, start

5, complete the experiment: the testing cycle (can be expedited) will be changed according to the sample and its testing items / methods, you can consult the engineer

6, issue a test report, and provide post-service.

In addition to the electrical performance inspection, environmental testing, and strength inspection of ordinary motors, the inspection of explosion-proof motors also requires the addition of necessary type test items and explosion-proof inspection items

① all factory inspection items; ② Connection wire torsion test; ③ Aging test of sealing ring rubber material; ④ Clamping test of the introduction device; ⑤ Sealing test; ⑥ Damp heat test; ⑦ Shell protection performance test; ⑧ Low temperature test

Test to verify whether the specified explosive gas mixture inside the explosion-proof electrical equipment can ignite the same explosive gas mixture around the equipment during explosion The product submission for review is divided into two stages. The first time was through the submission of user manuals, technical documents, and drawings for review. After the review of design drawings and technical documents, the product trial production can only be carried out. The entire trial production process must be strictly carried out in accordance with the design drawings and technical requirements. The second time is through the submission of a prototype for review. According to the explosion-proof regulations, inspect and conduct various tests on the samples submitted for inspection, confirm that the data is complete, and all tests are in compliance with the current relevant standards and explosion-proof regulations, before issuing the "explosion-proof certificate"

The operation of explosion-proof motors requires the issuance of an "Industrial Test License" for explosion-proof motors manufactured with new structures, materials, and technologies after passing the inspection. The products that have obtained the "Industrial Test License" must undergo industrial testing (according to the specified time, location, and number of units), product identification, and then be inspected by the explosion-proof inspection unit before issuing the "explosion-proof qualification certificate". The explosion-proof electrical products we have developed for mining have all undergone industrial tests underground in coal mines for 6 months, and the responsible industrial testing unit has issued an industrial test report to prove that the motor is working normally, reliable, and without any abnormalities

The explosion-proof motor can only be officially put into operation after obtaining the "Explosion proof Certificate", "Production License", "MA Safety Mark", and "Product Qualification Certificate". And limit its usage period (usually 5 years), when the usage period expires; When there are significant changes in structure, process, and materials that may affect product performance; When production is suspended for more than 2 years and production is resumed, a new inspection must be conducted. Only after passing the re inspection can it continue to be put into operation

In summary, due to the harsh working environment in coal mines, large temperature differences, and dampness, there is a possibility of force impact, movement, and falling, as well as the possibility of coal dust and gas.

. Therefore, the development of mining explosion-proof motors has its special requirements from design, trial production, inspection to operation. Therefore, the explosion-proof motor we have developed must meet these special requirements in order to play a positive role in coal mine production and safety
