Rig de perfuração rotativa KR150A

O torque máximo de saída é de 150kn.M, a profundidade máxima de perfuração pode atingir 52m e o diâmetro de perfuração da máquina também pode atingir 1300 mm. O mecanismo de luffing de cilindro único desta máquina possui operação estável e é muito fácil de manter e reparar. The two-segment masts have also been optimized to achieve automatic butt joints and folds, improving efficiency, and helping customers to worry less.In addition, the drilling depth measurement system has been innovated, which has higher accuracy than that of ordinary rigs. The main hoist bottoming protection device (a device that will alarm if the inverted mast is close to the ground) effectively reduces the difficulty of operation and makes the machine Handy when operating machines. The keys of the power head can be used in both directions, and they can continue to be used while they are worn and the other side, which doubles their service life.Very high safety performance, in strict accordance with EU safety standards, meet dynamic and static stability requirements, and ensure safety during construction.Low emissions, environmental protection and energy saving, meet the requirements of most developing and developed countries.The following is an introduction to an engineering case.
This project “power system underground pipe corridor project” is located in Nanjing.The project need construct under the high voltage line, so there is high limited requirement. A plataforma de perfuração rotativa é personalizada. Devido aos requisitos relativamente altos do cliente em equipamentos mecânicos e a lidar com condições geológicas complexas. The geology of this project is mainly soil layer, weathered rock, drilling diameter 800mm, drilling depth 15m, hole forming time is about 25 minutes, in general, 10 hours construction forms 21 holes, also with hanging steel cage in the middle. Formando a eficiência do orifício, bem como o desempenho da máquina para obter o reconhecimento do cliente.
