Shandong 2BZ-40/12 coal injection pump injection pump for mining coal injection pump use instructions Shanxi 2BZ-40/12 coal injection pump pulse 2BZ-40/12 coal injection pump manufacturers, coal injection pump price, pulsed injection pump, column piston pump, 2BZ-40/12 coal injection pump a wide range of coal taxes, taxes and administrative fees overlay, a heavy burden for the coal industry. According to the Deputy Secretary-General of the China Coal Industry Association, Zhang introduction, 2BZ-40/12 coal injection pump in the provinces before the round started to clean coal-related charges, taxes and fees of all kinds of coal projects involving less than 109, 2BZ- 40/12 coal injection pump tax burden to around 35% of coal enterprises the main business income. With the end of the "golden years" of the coal industry, 2BZ-40/12 coal injection pump coal companies had more bad days, the tax burden is too heavy for the negative effects of further demonstrated. 2BZ-40/12-type pulse coal injection pump, suitable for all types of coal seam water, especially in hard water coal seam water; is currently addressing the low permeability, high hardness, hard coal injection water the most effective techniques, is China currently only applies to coal seam water injection practices pulsed high-pressure injection pumps used in coal mine with an existing coal injection pump, compared with the following characteristics: ① water pressure, water flow pulse, adjust the upper limit of the intensity of water given in ( under pressure), water flow, pulse intensity (pressure) is automatically adjusted according to ability to penetrate the seams, seam pulse intensity with the ability to reduce water infiltration and increased pulse frequency remains constant pulse of water forced the closure of the original communication inside cracks and seams the formation of new cracks network; ② pulse pump fluid end brass as the base, with good corrosion resistance properties, can well meet the requirements of coal mine water corrosion; ③ coal injection pump pulse by pulse in the use of high pressure water injection enforce existing internal communication seam sealed cracks, fissures in the coal seam is formed inside the network, hydrostatic water infiltration composite coal injection mode in stop pulse-pressure water while the system automatically converts the static water; a, 2BZ-40/12 type coal injection pump pulse parameters 0-12 MPa ② ① pulse intensity output flow 40 L / min ③ pulse frequency 2BZ-40/12 coal injection pump motor power 15kw ⑤ ④ operating voltage 380/660 V, 660 / 1140V ⑥ size 1240X600X625mm ⑦ weight of 400 Kg Gast Shandong Mining Equipment Co., Ltd., for many years engaged in the production and development of mining equipment, with the strength to prove quality, welcome new and old friends to negotiate
