Description
Are intended for drilling of explosive wells with a diameter of 110 mm on open mining operations in breeds of average and high fortress, including abrasive, destroyed and jointed, with crowns of K-110, KNSh-110.
The pneumatic impact tool represents the pneumatic shock mechanism having avalvulvar system of airdistribution with the central supply of compressed air in working cameras of the cylinder and the central exhaust of the fulfilled air on a well face via the channel of the boring tool. Pneumatic impact tools are applied on drilling rigs and work at the compressed air-oil mix. Technical characteristics
Nominal size of a well, mm. 110
Nominal pressure squeezed, air, MPa. 0,5–0,7
Shock power, kW, not less than 2,8
Consumption of air, m3/min., no more than 5,8
Weight, kg 24
