What should the customer pay attention to when purchasing a drilling rig? How should the price be judged? How to solve the problem in the use of future failures, etc. These customers are more concerned about the problem, Xiao Bian will make one by one in this answer, I hope the following sharing can help everyone.
I. Precautions when buying drilling rigs and how to judge prices
The types of drilling rigs are various. Before buying, you must first define your own needs and budget. For example, if you buy a water well, you can buy a YT series drilling rig. If it is a piling hole, buy a reverse circulation rig. If you want to drill a stone well, Buy impact drill, if you want to hit the rock, then buy a pneumatic drilling rig, no water, no electricity, fast, 200 meters deep, 20 hours on it, generally with air-conditioned well, is the price is too high, 100,000 yuan can be estimated to buy Each type of 200-circular drilling rig is not suitable for the bottom layer of the rock. The rock can be hit. The 200 meters usually takes 20 to 30 hours. The 200-meter construction depth is accident-prone, and the accident is usually up to 2%. Therefore, it must be special. note.
The price of drilling rigs also varies greatly due to different models. At the same time, it is also related to the diameter, depth, well-drilling site, texture, etc. of the well being drilled. Most of the manufacturers can customize the products according to the customer's needs. In this case, the price should not be considered.
Second, the drilling machine can drill several wells
There are many kinds of wells for purchase, and there are corresponding drilling equipments for different types of wells. There are mainly four types of wells, ventilation wells, gas wells and rescue wells. Their specific role is as follows:
Ventilation wells mainly send fresh air from the ground to the bottom of the well, which serves to dilute the gas concentration in the coal mine and transport oxygen.
The main role of a well is to pump underground water and eliminate the hazard of groundwater to the coal mine production machine personnel during the excavation process.
There are two main types of gas wells: Drilling wells (straight wells, U-wells, and horizontal directional wells) in the coal seams at the site, and horizontal wells in the underground coal mines.
The rescue wells are mainly responsible for transporting and supporting people trapped in the mine from the ground. Small wells are drilled from the ground to deliver feed and communication equipment. The wells are generally only about 8 cm in diameter. The other is to hit a big well, take off or use it as a life-saving equipment.
Third, the treatment of rock encountered in drilling
Most drilling rigs encounter hard rocks in shallow formations. If conditions permit, drill holes using air-drilling hammers or drills for suitable bricks.
Drilling process of drilling machine
1. According to the requirements of the well's water output, the borehole structure is designed with a deep borehole, and the drilling machine type and corresponding auxiliary equipment are selected in combination with the conditions of the formation. Tower drilling machine development space, positive and negative cycle drilling machine is the largest crawler drilling
2. The machine should be leveled before the drilling, equipment layout, equipment storage, erection of towers, drilling rigs and other work.
3. Drilling into holes in loose formations, it is best to use impact drilling rig clear water pressure leveling hole expanding construction technology.
4. Drill holes in bedrock aquifers, preferably using rotary core drilling.
5. During the process of drilling into holes, a description shall be made to describe the stratified water sampling and temperature measurement according to technical requirements. Also ensure the quality and quantity of the sample.
The princple of the machine:
The Stoner is based on the proportion of grain crop and cobble density differences, by adjust the pressure and vibration frequency separate the stone and grain. The machine is equipped with a multi blade fan with high accuracy,The lighter grain crops will be suspended state, and the larger proportion of the stones will cling to the stainless steel mesh by adjusting the air pressure, and then by adjusting the frequency that Stoner table vibrates so as to achieve the purpose of separation. The machine equipped with frequency conversion control device can be subtle regulation, even if the proportion of the difference is very small, stones also will be separated. We are the De-stoner Chinese supplier.
