2ZBQ50 / 4 pneumatic injection pump manufacturers QZB50 / 4 pneumatic injection pump air injection pump manufacturers in Shandong 2ZBQ50 / 4 pneumatic injection pump iron ore prices continued to fall, is not conducive to foreign mining investment cost recovery. China's current iron ore overseas investment generally in high-priced investment, construction period elongated, prominent investment cost overruns. Because ore prices fell, 2ZBQ50 / 4 pneumatic injection pump future production capacity will not achieve the expected market returns, increased investment in business capital chain pressure, 2ZBQ50 / 4 pneumatic injection pump may even cause it can not afford to bring prices down The impact is low-cost acquisition of large international mining companies. As a professional manufacturer of excavators, 2ZBQ50 / 4 pneumatic injection pump, founded in 1972, temporary workers has created China's first generation of four tons loaders, but since a very long time, the old machinery is still not known to the public. 2ZBQ (QZB) Series pneumatic injection pump using compressed air as power, water spray can in large, high gas occasions safe to use. You can no longer turn the heat blocking problem. The advantage of working medium pump (slurry, compressed air) pressure signal is passed to form a closed-loop automatic control performance. So simple, accurate automatic control, no overpressure problem. The agency has a pneumatic pump reversing automatic positioning performance, safety and reliability. 2ZBQ QZB pneumatic injection pump can pump stepless row plasma volume, plasma discharge pressure. And having a predetermined discharge slurry grouting pressure automatically adjust the amount of performance. Can inject slurry single, double, and chemical pulp slurry. The pump has two liquid slurry ratio regulator (patent), in the grouting process can always stepless adjustment of the ratio of two slurries, and the ratio of the value of the benchmark instruction, grouting pump with pressure changes in plasma volume and automatically adjust row When the pulp than the regulator can automatically maintain the same ratio of two slurries.
