Spiral drill pipe, single spiral, double spiral, three spiral performance distinction?
Spiral number: single spiral, double spiral, three spiral of different design, is to meet the needs of different geological conditions and drilling process, especially with reference to the needs of slag efficiency and selection. Compared with multi-channel spiral, single spiral has the characteristics of large slag discharge thrust due to its smaller relative pitch, and drill slag is not easy to adhere to the drill pipe, which can better adapt to the looser and sticky drilling environment. Compared with multi-channel spiral design, the number of spiral turns increases, thus the movement time of drill slag in the borehole is longer, and the spiral thrust is relatively low. In the product introduction, the process should be selected reasonably according to the drilling conditions of the customer.

DTH drill in use should pay attention to what matters?
In order to use the down-the-hole drill correctly and ensure the drilling speed and service life of the drill bit, the following points must be paid attention to: 1. Select the down-the-hole drill bit according to the rock condition (hardness, abrasiveness) and the drilling rig type (high wind pressure, low wind pressure). Different forms of alloy teeth and tooth distribution methods are suitable for drilling different rocks. Choosing the correct down-the-hole drill bit is the premise to obtain the best use effect. 2. When installing the down-the-hole drill bit, the drill bit should be gently placed into the clamping sleeve of the down-the-hole impactor. Do not collide with force to avoid damaging the tail shank or clamping sleeve of the drill bit. 3. During rock drilling, ensure that the air pressure of the down-the-hole drill is sufficient. If the impactor is interrupted

What are the precautions before and during the construction of the hand-held pneumatic drilling rig?
1. preparation work 1. Before installing the drilling rig, the downhole air valve shall be opened to blow the viscera of the pipeline clean. The air pipe has the function of removing air and water. The pipe joint shall be cleaned. The oil mist device shall be filled with oil. The air pipe shall be connected properly. When water is supplied, the water pipe shall be connected to keep the water pipe joint clean. 2. The "three tightness" should be achieved in front of the eyes, I .e. tight cuffs, tight neckline and tight clothing corners. First, don't: don't wear gloves. In the 2. drilling construction, the drill pipe shall be installed with the drill bit and then into the drill sleeve. Then, the two hands hold the handle to stabilize the drill, align the drill bit with the drilling position, hold the air intake wrench by hand, and the air intake valve is opened (closed after loosening). The drill pipe starts to rotate. At this time two

What is an overshot and how does it work?
The salvage device is a new type of salvage tool for modern professional salvage or looking for sunken drill pipe bits. It is divided into male and female cones. How to work: when the fishing device enters the center pipe of the drill bit, the slider is moved up to insert the fishing device head into the center pipe. when the fishing device is moved up, the slider is moved down and tightened. the drill bit is lifted up by friction. after the fishing device is pulled out, the slider is loosened. the sliding device is tightened along the connecting rope on the block and the center pipe is pulled out. however, the position of the drill bit at the bottom of the hole should be determined before fishing device, A thin plate can be bolted around the bottom of the drill pipe, the drill pipe is dropped to the bottom of the hole, pressed onto the drill bit, and put it forward after waiting for a moment, which can be confirmed by observing the indentation left by the drill bit center tube on the board.

There are three kinds of geological spiral drill pipe products produced by our company, including: geological spiral drill pipe, rib drill pipe and grooved drill pipe. Characteristics and application scope of geological spiral drill pipe: geological spiral drill pipe is mainly suitable for deep-hole drilling construction with medium-hard and above geological conditions. Geological spiral drill pipe greatly improves the production efficiency of drilling construction and is the first choice for efficient drilling construction, energy saving and consumption reduction in coal mines. Characteristics and application scope of rib drill pipe: rib drill pipe has fast slag discharge speed and low rotation resistance during drilling construction, at the same time, it has the high strength performance and good slag discharge effect of geological drill pipe, because the spiral blade adopts large lead and plane structure design.

There are three main types of connections for geological spiral drill pipes: threaded connection type, square connection type, and hexagonal connection type; among them, square connection is mainly hexagonal connection. Common tetragonal specifications: F24, F26, F30, F32, etc. Commonly used hexagonal specifications are: B34, B35, B41, B45, B55, etc., of which hexagonal specifications have taper hexagonal: B41-B42.5B48-B49. The geological spiral drill pipe is made by our company on the basis of the high torque performance of the geological drill pipe, using single spiral blades or double spiral blades, prestressed winding and fully automatic welding. The drill pipe body adopts high
