Rig Working System And The Matters Needing Attention

A, broken pipe: 1, vehicle rig drill pipe fracture and pore wall friction, mostly belongs to drill pipe to pipe wall thickness thinning, strength too weakened, and make the drill pipe rupture. 2, prevention, treatment, and joint pipe should pay attention to check, when to stop using the friction losses of excessive drill pipe. Second, is not ring: 1, the common has the following four conditions: (1) the valve broken; (2) the liaoning rig drill bit tail broken broken hammer ballastless stuck into the cylinder body; (3) vent was rock powder block; (4) the chisel, down hole water exhaust resistance is big, more is not easy to start. 2, the processing methods: found itself is not ring, according to the above four reasons to check first; Check method is to elevate impactor, reduce exhaust resistance, part of the water jet, then slowly into the bottom of the hole, if the law problems, is likely to belong to the former three reasons, need is unloaded to clean or replace another piece.

Binzhou rig working system and the matters needing attention: drill equipment simple manipulation, using performance is strong, easy maintenance, less investment, is a good helper for farmers to get rich. Relatively large drill work system, the working conditions and working characteristics of unit to each are not identical, therefore, we according to the work of the unit characteristics of drilling rig, the working system of drilling rig is divided into three parts, namely the rotation system, improve the system and circulatory system. In addition, also have a separate clause for rig substructure system. In this way, a complete set of on-board rig is composed of the following eight system equipment. Rotation system equipment and tools. Circulatory system equipment and tools. Improve the system equipment and tools. Power drive system equipment. Transmission system equipment. Display instrument control system and detection. Rig substructure. Auxiliary equipment.

Anchor drilling machine is designed for water conservancy, traffic engineering, building materials, construction site of a new type of efficient drilling equipment, widely used similar type management, water conservancy, road construction, and all kinds of open-pit mine, geophysical exploration of engineering of rock drilling anchor hole or holes. Jumbolter used in foundation engineering construction, and can complete anchor construction, powder, mortar and all kinds of engineering exploration hole, micro pile hole drilling, and can realize the spiral dive hammer and scraper drilling. Hydraulic rotary spray drill for full hydraulic pressure drive, power head type drill, sinker is suitable for vertical or inclined drilling and spray, spray, jet grouting pile construction equipment. Applicable to the soil, sand, sand gravel of quaternary overburden high irrigation plasma operation. According to the special requirements of users, research, design, production of special purpose and requirement of equipment and machinery. Impact drill can meet different geological situation, the impact drill is a kind of important drilling filling pile foundation construction of machinery. Liaoning rig especially pebble layer in drilling, impact drill adaptability compared with other type of rig. At the same time, use the impact drill hole, hole, hole wall form a layer of compacted soil around, the stability of hole wall, anchorage drill improve the bearing capacity of pile foundation, have certain effect.
