3NB-300 / 12-45 drilling rig mud pump mud pump mud pump mud pump reciprocating rig drilling rig mud pump mud pump mud pump model mine factory smooth 3NB-300 / 12-45 mud pump market performance of domestic anthracite coal yield progressively complex recovery, 3NB-300 / 12-45 mud pump but overall turnover remained inadequate. Around coal prices coal sales turnover rate is not high, still a long association for heavy users, the market outlook is still weak or stable operation. Taiyuan Coal Trading Center 3NB-300 / 12-45 mud pump analysis showed that the current price stability maintenance Shanxi Jincheng area, parts of the region Yangquan Coal prices lump price up 20 yuan / ton. Although anthracite civilian market is relatively good, but the downstream fertilizer, chemicals flat overall market situation continues, demand for anthracite difficult to pull clear in the biography 3NB-300 / 12-45 season mud pump system failed to sell well. Jincheng Anthracite market remained stable, multi-demand procurement and downstream enterprises to a long association orders based; 21 coal units "eleven" before Yangquan belongs shutdowns were overwhelmed overhaul some extent affected the local lump supply, some local 3NB-300 / 12-45 mud pump lump of coal prices raised the price of 20 yuan / ton. 3NB-300 / 12-45 Parameter Type Horizontal triplex mud pump reciprocating single-acting piston pump stroke length (mm) 110 Bore (mm) 75 Pump Speed ??(min-1) 206 153 112 82 Flow (l / min) 300 220 160 120 Pressure (MPa) 6.0 8.0 10.0 12.0 volume ratio (%) 85 Total efficiency (%) 72 required power (Kw) 45 maximum suction height (m) 2.5 inlet diameter (mm) 3-inch cloth pressure hose 76 drain diameter (mm) 2-inch two-wire high-pressure hose 51 Dimensions: Length X Width X Height (mm) 2020X1100X1130 Weight (Kg) 750 Gast Shandong Mining Equipment Co., Ltd., for many years engaged in the production and mining equipment R & D, with the strength to prove quality, welcome new and old friends to negotiate
