BPZW8031.5 spray pump
A, 2BZ-40/12 type pulse pump overview
2BZ-40/12 type pulse water injection pump is suitable for various types of coal, especially coal difficult: the water flooding is the most effective means to solve the low permeability, high water hardness hard coal seam water injection, is currently China's only used in high pressure injection type coal seam water injection pump pulse practice.
Compared with the prior applied to coal pulse pump has the following characteristics:
1.The injection pressure, injection flow as the pulse, water injection strength in limit setting (pressure), the flow rate of injection, pulse strength (pressure) is automatically adjusted according to the permeability of coal seam, reduce the pulse intensity with coal on the water penetration capacity increased, pulse frequency remains constant, pulse water forced communication within the original coal seam closed fracture and fracture network new;
2.The pulse pump hydraulic end of the brass as a matrix, with corrosion resistance is good, good to meet the water requirements of corrosion of underground coal mine;
3.The coal seam water injection pump pulse by pulse of high pressure water flooding forced communication seam closed fracture, the original formation of fracture network in coal seam inside in the use of water infiltration, composite static pressure water injection in coal, stop at the same time system of pulse high-pressure water injection is automatically converted to static pressure water injection;
2BZ-40/12 type pulse pump generally use the complete delivery. Pulse seam water injection pump sets include: 2BZ - 40/12 type pulse pump, water injection pressure meter, integrated block, automatic water supply tank and sealing pump.
