ACW-1 gas pressure tester Industry: Mining ACW-1 gas pressure tester pressure method is to measure CH4 seams of special equipment. By liquid sealing of new technologies. To the various types of mines, under the conditions of different rock seams real measured CH4 correct pressure is the pressure measured CH4 latest products. Item Unit Value Remark measured pressure MPa 0 ~ 8 - Mucus cylinder pressure MPa 0 ~ 8 - sealing depth m 8 can be increased to more than 20M length m 1.8 liquid seal can be increased to more than 3.6M hole diameter mm φ61 ~ φ63 drill Each section of pipe diameter φ60 Length m 1.8 - Before assembly dimensions mm 1950 × 370 × 250 length × width × height Jining Branch-mining equipment, large favorably, please call
