2NB type mud 2NB type mud Overview NB series of coal mines with a mud pump is a single cylinder or double-cylinder reciprocating pump, single acting, double acting plunger and piston structure. Accounted for mainly used for geological exploration, supply flushing fluid (mud or water) cooling the drill diluted clay, mud and circulation function. Supply downhole drilling for coal mine tunnel drilling fluid. Cooling drill Paixie. Pressure Note the mud used in the coal seam fire fighting as well as sealing grouting. Can also be used in ground engineering construction reinforced blocking lubrication grouting water grouting and pipe jacking pipes between appearance with soil. Its characteristics are: simple structure, easy operation and maintenance, and reliable operation. Small size, light weight, easy transportation and installation power and is installed in the same base. 2NB Mud Pump Model preparation instructions 2NB mud pump works (1) NB-type mud-cylinder single-acting reciprocating plunger pump. Motor through V-belt, shaft, eccentric disc and rod driven plunger reciprocates. Plunger every reciprocating, the slurry valve inlet and outlet to complete a suction slurry and rows of pulp action. (2) 2NB type the model pump-cylinder double acting reciprocating piston pump. Motor through V-belt, drive shaft, clutch, and gears rotate the crankshaft, connecting rod, rod, piston reciprocating. Reciprocating piston, the piston back and forth between the two groups into the exhaust the slurry valve each complete a forward row pulp actions. Four the 2NB type mud pump selection. Based on the use of different occasions, supporting mud pump is divided into two kinds of explosion-proof and non-explosion-proof motor. Coal mine with explosion-proof motor must be selected. 2.2NB type mud If you do not want to supporting the motor, in order: base and pulley whether restructuring. 3.2NB250/4-22 type mud can be changed according to the user needs the original TBW200 / 4 type mud with 18.5KW motor for ground construction. 4.
