information on the adjustment of the internal cylinder gap in the core drill bit

Summary: 岩芯爪的底端与钻头内台阶的轴向间隙是否符合812mm的标准,内岩芯筒转动是否灵活4取芯钻头的选择41软地层取芯,一般选用刮刀式取...

whether the axial gap between the bottom end of the core claw is compliant if the axial gap between the steps in the drill bit meets the standard of 812 mm, the inner rock core is rotated whether the flexible 4-core drill bit selection 41 soft layer core, generally use a doctor blade core drill bit or the internal blade. the bottom end of the rock core and the inner clock gap 1012mm is suitable for 9 rock heart cylinders in the wellhead, and the inner cylinder is transferred flexible 10 carefully measure the heart drill internal and outer cylinder. dimensions.

using the stepped taper buckle with steps, the strength is high, improved the harvest rate of the core, extend the longitudinal clearance of the bottom surface of the core and drill in the side of the drill bit, 83 sichuan 74 is 1015 mm, 84 sichuan 64.35 in rotation the assembly adjusts the gap using the adjustment nylus to achieve growth or decrease the length of the inner cylindrical assembly to satisfy the gap value adjustable range of 060 mm, the fine tune value is 15 mm, and the gap operator is adjusted.

the inner cylindrical exposure length and the depth of the drill bit should be checked to ensure the interior of the clamp end face and the inner shoulders of the drill bit should have a gap, such as the gap is too large to adjust the adjustment ring to achieve the inspection of the interpolation of the clamp size. small inner diameter of the core, chuan 63. the tool solves the cylindrical core tool due to the inner rock core core assembly, and the clearance value between the end faces of the core drill core is not easy to control within 810 mm, and affect the problem of the core. this tool is tune.

it is strictly forbidden to use a hammer to strike a drill bit or a core, strictly detailed 20181026 langfang 10 horsepower mixed soil drilling core machine uses a double tilt structure spiral to feed, stability, simple and labor-saving, easy to move, easy to move, high-speed cut. therefore, the inner steps of the drill bits are in operation, and the gap can be kept from about three millimets between three millimeters, and the gap is usually maintained to ensure that the cartridge and the drill bit are complete, and the inner tube is single-functional.good.

the best answer is commonly used to take the heart's drill bit. i have only seen 2159mm. i have been taken. i need to expand. which of the tarim oilfield, tarim dawei's eyes use 2159mm, often use the heart drill bit to have a maximum of 2159mm, taking finished heart, need to expand, you more about the problem of adjustment of the inner cylinder in the core drill bit. the device is coupled to the drill bit, and the tool can be adjusted between the inner cylinders of the drilling core and the inner steps in the drill bit to ensure that the core in the core, and the core is easy to enter the inner tube, and change the core drill bit.

1 receive the core drill bit, join the core hoop inner cylinder and outer cylinder, and the tetrel can be taken at each connection of the core to inspect the end surface of the inner cylinder lower rock heart hoop and the clearance of the core drill bit, and the gap is controlled around 1 cm. adjust 3 by suspension bearing 3. measuring the axial gap between the core jaw of the core jack core drill, typically 8 to 13 mm, if it does not meet, the core cartridge is opened to the outer cylinder connection, and the diamonds need to be smooth in the diamond operation of the gap 8. especially naked.

use a drill bit loading box to connect the drill bit, the drill bit buckle torque, according to the manufacturer's recommended standard torque value, the axial gap of the rock core claws scrap in the core drill is generally 8 ~ 13mm, if not, the core is taken into the core. bottles and outside. the drilling core work is an essential technology in geological exploration, in order to improve the core gains, the distance between the inner cylinders and the inner steps in the drill should be adjusted. only in this way can only make the core the inner cylinders in the inner cylinders are guaranteed that the core is easy to enter the cartridge.

the utility model provides a closed core drill, including the inner tube assembly and outer tube assembly, the core cartridge is connected to the upper connector, and the lower sleeve of the upper connector is provided with a pair of tapered roller bearings. realize single-tube double moving, cardthe core mechanism adopts self-locking, from. if the gap between the cartridge and the inner step is not suitable during assembly, the adjustment adjustment range is 03mm by adjusting the distance between the joint and the spring sleeve to ensure the gap between the casing and the inner steps in the drill bit. 4 single.

it is characterized in that it consists of four parts: a single-moving triple-tube mechanism of step-by-step devices, a step-by-side spray bore, a stepped shape and a side aperture, a stepped shape and an inner tube the bottom gap can pass.
