BW-250 mud pump            BW-250 mud pump is a horizontal three-cylinder reciprocating single-acting piston pump. The pump has two kinds of cylinder diameter and four-stop variables. The large cylinder liner is used for matching 1000-meter large-caliber drilling rig, and the small cylinder liner is used for matching 1500-meter small-caliber drilling rig. It is mainly used to transport mud with core drilling rig. It can also be used for other purposes such as grouting, mine drainage and long-distance water supply.            main features            1. It has four-stop flow which can meet the needs of large and small-caliber drilling rigs. It has a wide range of flow regulation and reasonable parameter selection. It can be used in conjunction with XY-4 core drilling rig and XY-5 drilling rig. It can meet the needs of different caliber, different Kong Shen and different geological core drilling.            2. self sealing S type polyamine rubber piston with bowl shape and nylon back is greatly improved.            3. Five dust-proof sealing rings are arranged on the pull rod to prevent the slurry at the hydraulic end from being brought into the power end and the lubricating oil filter at the power end. Many production tests have proved that the sealing is reliable and the performance is good. Cause the gear to extend the service life.            4. the intake and drain valves are made of steel balls. A noise reducing rubber pad is arranged on the valve cover to reduce the impact noise.            5. the pressure gauge uses BY-1 type earthquake resistance pressure gauge, the life is long.            6. compact structure and beautiful appearance.            7. good detachability, easy maintenance and relocation.            Technical parameters and specifications            Type horizontal three cylinder reciprocating single acting piston pump            Stroke length (mm) 100            Bore diameter (mm) 8065            Pump speed (min-1) 200116724220011672 42            Flow rate (liter / min) 250145905216696603            Pressure (MPa) 2.5 4.5 6 6 6 4 6 7 7            Floor area ratio (%) 85            Total efficiency (%) 72            Required power (Kw) 15            Triangle belt pulley diameter (mm) B type X5 slot 410            Input speed (r/min) 500            High water absorption height (m) 2.5            Inlet pipe diameter (mm) 3 inch cloth pressure resistant hose 76            Drainage pipe diameter (mm) 2 inches two layer steel wire high pressure hose 51            External dimensions: long X width, X high (mm) 1100X995X650            Weight (Kg) 50
