Mine Explosion BW-250 mud pump manufacturers Which is good proof BW-250 mud pump manufacturers

Mine explosion-proof choice for high-quality BW-250 mud pump manufacturers Hebei Jiaxiang, reliable quality and reasonable price, after-sale protection BW-250 mud pump manufacturers introduced, BW-250 mud pump manufacturer, BW-250 mud pump model is complete, BW-250 mud pump reliable quality, after-sale protection BW-250 mud pump is a horizontal triplex reciprocating single-acting piston pump, which has two variable bore and Si Dang, large cylinder liner for 1000 meters of large diameter drills small cylinder liner for 1500 meters of small diameter drills. Core drilling rig is mainly used for transporting mud, can also be used for other purposes other grouting, mine pollution and long-range water supply and so on. ◇ Main Features 1. meet the large flow of small diameter drilling rigs each four gear required, flow adjustment range, parameter selection is reasonable. With XY-4 and XY-5 Core Drill type drilling rig. Can meet different caliber, different hole depth, the needs of different geological core drilling. 2. The piston bowl shape and nylon backrest of self-styled S-type polyurethane rubber piston, greatly improve the life. 3. The upper link is provided five dust seals to prevent fluid end of mud into the power end and power end lubricating oil filter. After several production test proved reliable seal, good performance. Causing gear extended service life. 4. into the drainage valve with the ball. And the valve cover with a sound reduction rubber pad to reduce the impact of noise. 5. BY-1 type pressure gauge seismic pressure gauge, long life. 6. Compact structure, beautiful shape. 7. detachable good, easy maintenance and relocation. ◇ Technical parameters and specifications Type Horizontal triplex reciprocating single-acting piston pump stroke length (mm) 100 Diameter (mm) 80 65 pump speed (min-1) 200 116 72 42 200 116 72 42 Flow (l / min) 250 1,459,052,166,966,035 pressure (MPa) 2.5 4.5 6.0 6.0 4.0 6.0 7.0 7.0 Floor Area Ratio (%) 85 Total efficiency (%) 72 required power (Kw) 15 sheave pitch diameter (mm) B type X5 tank 410 input speed (r / min) 500 maximum suction height (m) 2.5 inlet pipe diameter (mm) 3-inch cloth pressure hose 76 Drain diameter (mm) 2-inch two-wire high-pressure hose 51 Dimensions: Length X Width X High (mm) 1100X995X650 Weight (Kg) 500
