Not only to explore the material resources, but also to explore the human resources; not only to explore the reality of resources, but also to explore the potential of resources; not only direct resources to explore, but also explore the indirect resources; not only to explore space resources, but also to explore the time resources; not only to explore the intellectual resources, but also to explore the emotional resources; Visible only to explore the resources, but also to explore the intangible resources. This is the road Machinery Co., Ltd. Shandong Long development. We always adhere to the "quality first, customer first" principle, warmly welcome guests to the company to discuss cooperation! Development phenomenon submersible drilling rig industry, DTH drilling rig construction pile drilling rig parts prices, submersible drilling rig works Detailed widely used in drilling and other projects, but many applications are concerned, the use of submersible drilling rig is still very strange because submersible drilling rig has his own unique in its design and construction. Want to learn the use of submersible drilling rig, you must understand the structure and working principle of submersible drilling rig. Although largely submersible drilling rig and the general pile hole drill rig differ, but this is the rig in a roughly similar principles and submersible drilling rig. DTH DTH hammer drilling machine is composed of a piston inside the cylinder, valve seats, check valve and drill accessories installed in the elongated outer cylinder, outer cylinder fitted with a wrench on the mouth and has a threaded coupling the joint, with the bottom of the card solder sleeve threaded connection. Card is mainly used for brazing sets propulsion and rotary motion passed to drill. Card-loop control drill hole drill pile axial movement manufacturers, and the check valve is the time when the supply of compressed air is used to harm only rock ballast and other debris into the impactor. Submersible drilling rig in the use and maintenance, because the impact of the joints and fittings are right-hand thread, so the drilling operation, the impactor should always keep the right maneuver. When opening, the impact should be minimal and propulsion, the drill into the rock steady. Propulsion and drill weight matching is important, with the propeller thrust to be the weight of the drill string changes. yz6 pile drilling rig _ Long industry machinery (certified) _ pile drilling rig provided by Shandong Machinery Co., Ltd.
