Fushun Meike Self-rescuer Air-tightness Tester Factory
Fushun Meike Self-rescuer Air-tightness Tester Factory is located in Liaoning Province, Fushun Economic Development Zone.
ZJ series air-tightness testers for self-rescuers of our factory was designed by Mr. Wu Yonghuo, senior engineer of Fushun Branch of CCRI, who has been studying on coal mine rescue instruments.According to positive pressure principle, "drying method" testing is used. Each self-rescuer can be tested in only 15 seconds.
In June of 1985, type ZJ-2 air-tightness tester for self-rescuer won silver medal at the first Coal Industry Science and Technology Achievements Fair.
Because ZJ series air-tightness testers for self-rescuers have the incomparable advantages that "wet method" testing doesn't have, they were proposed to be used in coal mine, according to Clause 2.5.2 of coal industry standard ¡¶MT/T5016-96 Standard for the Equipment of Ventilative Safety of Colliery¡·
