The temperature is high in summer, and the rotary drilling rig is operating in such an environment, and the components face many tests. Good maintenance work can ensure the stable operation of the rig and extend the service life. The following introduces the key points of summer maintenance of rotar Read More

1. Check the appearance of wear: If the drill shell, drill pipe and other parts have a large number of scratches and deformation, it indicates that it is used frequently, which may affect the subsequent life.2. Check working hours: the number of working hours is large, the components run for a long Read More

1. Mud wall protection against hole collapseWhen drilling the loose soil layer is easy to collapse by the horizontal soil pressure, the mud balances the soil pressure by the outward pressure, forming a stable ‘mud skin’ to protect the hole wall.2.Characteristics of non-circulating mud processThe rot Read More
