The working principle of the toothed tri-cone bit is basically the same as that of the turbo compressor, but because the gas flow rate is low, the pressure change is not large, and there is generally no need to consider the change of the gas specific volume, that is, the gas is treated as an incompressible fluid. It is widely used in factories, mines, dust exhaust, ventilation and other related fields. The design of the flow is designed for larger air volume requirements, and its adjustment method is controlled by baffles, dampers, return, start and stop motors, etc., which cannot form a closed loop control, and does not consider the concept of power saving. The roller cone bit wants to be used for a long time, and the usual maintenance work is indispensable.
Frequent maintenance will not cause major problems. The basic use environment should always be kept clean and the surface of the roller cone bit should be kept clean. There should be debris. Regular roller cone bits and dust and other debris in the pipe. Electricity-saving principle of toothed tri-cone bits Any production machine that uses AC induction motor as a power transmission mode, and most of it cannot run at full load during work. The power of the motor is selected according to the rated load during the larger load period.
The motor works at full voltage, full speed, and the load is small, and there will be a lot of time for no-load operation.tricone bit is a kind of bit that changes the early use in drilling. It is assumed that the design and application are robust, and in soft formations, faster speeds and more footage can be obtained. The scraper bit has a simple structure and is convenient to manufacture. A drill with a diamond composite sheet as a cutting edge is called a diamond drill. The drill bit is an integrated drill bit, the whole drill bit has no moving parts, the structure is relatively simple, and it has high abrasion resistance and impact resistance. It is one of the three new technologies in the world in the 1980s. Field application has proved that when drilling in soft, medium and hard formations, diamond drill bits have the advantages of large footage, long life, stable duty, less downhole disturbance, and good well quality.
What are the functions of the tricone bit?
(1) The main method of impact and crushing action: the impact force and static pressure of its longitudinal oscillation all lead to the impact and crushing effect of teeth on the ground, forming volumetric crushing pits.
(2) Erosion effect of jet stream: The jet stream sprayed through the nozzle has an impact effect on the rock in the well, and assists the fragmentation of the rock.
(3) The shearing effect of the tooth itself: When the tooth eats the rock under the action of axial pressure (weight on bit), the wedge-shaped surface of the tooth produces a horizontal shearing force on the rock in contact with it, and the rock follows the shear surface. Shearing and fragmentation occurs, and the broken rock is removed with the movement of the teeth. This is the shearing effect of the tooth itself on the rock.
(4) Auxiliary method: Sliding and shearing action: The radial and tangential movement on the teeth makes the shearing effect appear in the well, and the rock between the teeth is broken.
Tooth tricone drill bit is under the effect of weight-on-bit and drill string rotation. After the teeth are crushed and the rock is also eaten, the corresponding sliding and shearing of the rock occur at the same time. When it is rolling at the bottom of the well, the teeth on it will sequentially impact and press into the formation. This effect can crush a part of the bottom rock, and at the same time rely on its sliding to weaken the shearing effect of the teeth. The remaining rocks in between caused all the rocks at the bottom of the well to be broken, and the wellbore was extended.
The application of toothed tri-cone bit is generally equivalent to the application in a confined space. For confined spaces, the cone bit believes that it is closely related to modern life. With the rapid development of human civilization, the types and quantities of chemical products and electrical equipment entering the room have increased. Houses have been built more densely. Indoor pollution factors have increased day by day, but the ventilation capacity has weakened. This makes some indoor pollutants The concentration is several times higher than that outdoors. Indoor air pollution refers to the behavior of indoor environmental pollution caused by various reasons that the substances in the indoor air exceed the standard, which in turn affects human health. Substances include formaldehyde, benzene, ammonia, radioactive radon and so on.
It can be seen that we need ventilation very much in our lives. Cone bits are indispensable in various fields. The use of them in theaters and workshops creates a stable environment for everyone. The contribution in industry is also indelible, creating rich industrial value, and now it has also been applied in agriculture, and it has become an important equipment for auxiliary food storage. The diverse needs of the industry are driving the performance of roller cone bits. The wonderful roller cone bit technical team will further deepen the integration and understanding, and meet the needs of all parties with excellent equipment.
