Product Investigation of Meishan Qingshen Engineering Drilling Rig Type Wire Rope Impact Rig. It consists of a mast and a lifting pulley, a steel wire rope, an impact, a drilling tool, and an electric motor installed on the top. During operation, the motor drive device drives the impact to drive the wire rope to make the drill reciprocate up and down. When moving downward, it cuts and breaks the rock formation by the weight of the drill bit, and moves upward by the wire rope. The drill stroke is 0.5 to 1 meter, and the impact frequency is 30 to 60 times / minute. The cuttings are cleared from the ground by a sand extraction tube, and drilling and removal are performed simultaneously. Technical Service In addition to the daily maintenance during construction of Meishan Qingshen Engineering Drilling Rig, it is also necessary to perform regular maintenance on important components in accordance with requirements. The following 5 points need special attention: Before each work, you must fill the engineering rig lifter with butter. When filling the lifter, be sure to open the other end of the grease nipple, which will help squeeze out the previously poured butter, and vice versa The oil seal in the lifter may be crushed. Dirty water containing sediment is easy to enter, which will wear the bearings and reduce the sensitivity of the rig lifter. Good new quotation The casing of the cement injection construction process goes down to a predetermined depth → loading the cement head, circulating mud, ground surface pipeline → hitting the isolation fluid → cementing → top rubber plug → replacing the mud → pressing pressure → cementing is finished, and setting is waiting. Regularly clean the North Pass with diesel or diesel to clean the impactor, wind motor, and observe the damage of the motor blades. There are two types of prices: The type is to add impact on the basis of rotary rotary rigs, mainly for rotary drilling. When encountering pebble layers, dual-use well rigs with impact drilling are more adaptable to various formations. Strong; the other is a water well rig that combines impact and slewing action in the drilling, such as a wind-driven down-the-hole hammer rig. The down-the-hole hammer drill used by it is composed of a cylinder liner and an up and down movement in the cylinder liner. The lower end of the cylinder liner is connected to the drill bit, and the upper threaded joint is connected to the drill rod. The high-pressure air of the air compressor of 0.7 to 4 MPa, the check valve above the air distributor, and the air inlet below push the impact frequency as 700 ～ Up and down reciprocating motion of 1200 times / minute, which frequently impacts the drill bit to enhance the drill bit's ability to drill into rock formations. At the same time, the drilling tool rotates at a relatively low speed of 35 to 60 rpm. The air from the upper and lower cavities enters the drill bit downwards, cooling the role of the drill bit, and bringing the cuttings at the bottom of the hole out of the wellhead. The structure of the rotating and circulating well-washing part is basically the same as that of a rotary table rotary drilling rig for washing wells with compressed air. The drill bits used are tungsten carbide ball-tooth drill bits or roller drill bits. Pneumatic down-the-hole hammer rig can be used for drilling deep wells in hard rock formations. The drilling speed is high, and the drilling speed does not decrease due to the increase in drilling depth. The boreholes drilled are relatively straight. Investigation of drilling rig products of Meishan Qingshen Engineering Drilling project shall ensure smooth drainage at the construction site and avoid rainy season. When digging the soil, the small water well drilling rig should be determined according to the physical and mechanical properties of the soil layer, which is generally 1: there must be a certain distance between the soil slope and the top of the excavation. For large wells with water in the wellbore, the inlet hole and filter layer of the wellbore must be arranged according to the design requirements, and the inlet hole should be blocked during construction. The filter material buried in the aquifer should meet the requirements, and the backfill should have a fixed height. In winter, Meishan Qingshen Engineering rig is a good manufacturer, and the frozen soil in the backfill should not exceed 15%. When the customer first disassembles the part, the positioning pin should be removed before performing other disassembly work. During installation, the positioning pins should be installed after positioning, and then install other parts. trustworthy

When packing and distributing machinery and equipment, special protection measures must be taken on oil pipes and joints, hydraulic valves, gears, racks, sliding guide rails and other vulnerable parts. Do not drag on the ground during transportation. When handling the equipment, do not bump the operating handles, let alone twist them hard. Hydraulic drilling rigs are also known as hydraulic drilling rigs. Hydraulic drilling rigs are generally good rotary drilling rigs. The main types are rotary drills, impact drills and compound drills. This type of drilling rig uses diamond, cemented carbide, drill bit and fish tail drill, etc. It can perform core drilling and full-hole drilling without coring, and it can also be used for impact drilling with a hoist. Separately packed spirals and spirals are packaged separately to avoid mixing high-strength spirals, other spirals and spirals. Meishan Qingshen stuck drill: good new quotation Small water well rig system is equipped with power system, water well equipment quality, means of energy for the entire drilling platform; work system, equipment that works according to process requirements; a transmission system, a kind of transmission to the work unit, transmission And devices that distribute energy; systems, each system and equipment, coordinate and accurately work according to process requirements; auxiliary systems, direct sales of water well rigs, and equipment that assists the main system. We know that the torque of the drilling rig is fixed, so how does the torque value of the drill stem originate from and consist of these factors? Manufacturing costs The basic classification and common categories of Wuwei water well drilling rigs: The essence of drilling is to try to solve the problems of broken rocks and cuttings, protecting the wall of the well, and continuing to deepen drilling. Water well drilling rigs are required to complete operations such as drilling water wells, running pipes, and washing wells. Long-term good practice and scientific research have boiled down to two types of drilling with industrial practical value in drilling: impact method and rotary method. From these two evolutions, a variety of rig models have been derived. Product survey of Meishan Qingshen engineering drilling rigs All-hydraulic operated drills are also called full hydraulic drilling rigs. A drilling rig driven by oil pressure and all moving parts. This type of drilling rig uses the high-pressure variable oil pump to achieve stepless speed change. The model of Meishan Qingshen Engineering rig can simplify the transmission and remove the gearbox, which not only reduces the weight of the rig, but also has sufficient power. At the same time, the speed of the drilling rig is high, and the work is stable. The types of drilling rigs in Meishan Qingshen are convenient and safe to operate, and easy to implement automation and instrumentation. It is especially suitable for high-speed drilling (such as diamond drilling). However, the processing of the hydraulic components of this rig is more complicated, and the requirements for use and maintenance are relatively high.  From the structural point of view, all hydraulic drilling rigs can be divided into two categories: vertical shaft full hydraulic drilling rigs; and power head full hydraulic drilling rigs. Summary of solution customization: Engineering rigs are an indispensable device in our infrastructure construction. With the continuous development of science and technology, the scope of use of rigs is also increasing, bringing a lot of convenience to our daily lives.

It is strictly forbidden to remove the protective cover when investigating the drilling rigs of Meishan Qingshen Engineering. Before the bidding operation: When guaranteeing the quality of the transported machinery and equipment, the equipment should be in a normal state, not tilted or inverted, and must be installed stably and bundled firmly. 1 When lifting or lowering the casing with a pulley, and when the machine is fishing, all should leave the well. 4 For limestone, drip small pieces from the wall or hole of the hole, or place it in a larger gap or solvent. For more information, please check the prevention of water well drilling rig bit slippage: The slippage phenomenon can be overcome. First, combine the depth of the single bucket on the display. Although the drilling resistance of the mud layer is small, as the slag inside the drill bucket increases, resistance to the slag inlet will be generated, so the drilling resistance is increased. The sound of the planetary reducer on the power head changes with the resistance, so listen to the sound of the power head Can determine the amount of footage. When the drilling resistance increases, the speed of the power head also decreases, so the speed of the drill pipe can also determine the amount of footage. If the geological changes are not great, the drilling time and depth of each bucket should be kept within a certain range, and the depth of the single bucket in the mud layer should be within 0.5 to 0.6 meters. When the bucket bottom is reversed and closed, try to drill when there is load. At this time, the bottom of the bucket has a certain resistance, so as to prevent the bottom of the bucket and the drill pipe from being reversed. The earliest water well drilling platforms in the world appeared in Switzerland in the late 19th century, when they were driven by humans and later by steam engines. In the 20th century, internal combustion engines and electric motors gradually replaced steam engines. Early rigs were mechanically driven, the structure was relatively simple, and the supplier of water well rigs had poor performance. Since the early 1950s, it has developed into a combination of machinery and hydraulics, the purchase of water well drilling rigs, increased speed changes and some instrument parameters. Since the 1970s, in order to adapt to high-speed diamond drilling, the hydraulic degree has increased. The speed of drilling rigs for water wells can reach 1000-1500 rpm, and some can reach 2400 rpm. The drilling efficiency has also been greatly improved. Since the 1980s, rigs have developed rapidly around the world. Because the hydraulic technology has the characteristics of solid connection, concentrated, labor-saving operation, and a wide range of torque and revolutions, the entire hydraulic rig has been developed and applied. In order to meet the requirements of various drilling process parameters, a multi-function drilling machine with multi-process drilling is introduced one by one, and a device can be used instead of a device with multiple impossibility. With the increasing depth of the cai mine, water well drilling platforms continue to appear, and the use of computers to make scientific drilling a reality.
