The geological exploration car rig rotates and the vertical shaft shakes back and forth. What's going on

1. Variable speed bending deformation, excessive wear, loose fixing screw or variable speed rod deformation, etc., so that the gear cannot mesh normally.The self-locking device is worn loosely, and the spring elasticity is insufficient or broken, resulting in insufficient locking force, so that the variable speed fork shaft cannot be reliably positioned.

2. The other is a well drilling rig that combines impact and rotation, such as an air-dynamic submersible hammer rig. The submerged hammer drill is composed of cylinder liner and piston, etc. The air compressor provides high-pressure air to push the piston up and down, and impacts the drill bit to enhance the ability of the drill bit to drill into the rock layer.

3. Technical improvements have been made on the original rig. The shaft diameter device has been added to the clutch part to enhance the strength of the active shaft, and the gears in the rig gearbox have also been strengthened and improved in materials and processes on the original basis.

4. A rig is a set of complex machines, which is composed of machines, units and mechanisms. The rig is exploring orIn the development of mineral resources (including solid minerals, liquid minerals, gas minerals, etc.), the machinery and equipment used to drive drilling tools underground to obtain physical geological data. It is also known as a drilling machine.

What is the working principle and basic composition of the vehicle-loaded drilling rig?

1.: The impact drilling rig relies on the vertical reciprocate movement of the drilling tool to make the drill bit hit the bottom of the well to break the rock layer.

2. The drilling rig is an integral layout (Figure 3-1), which is composed of five major parts: the mainframe, the control table, the pumping station, the crawler body and the stabilizer device. The mainframe, the pumping station and the control table are connected by high-pressure hoses and installed on the crawler body. The structure is compact and convenient for underground relocation and transportation.

3. The structure of the table drill is generally composed of motor, base, spindle, workbench, cylinder, feed box, spindle gearbox and other components. The motor can make the spindle change at five speeds through five variable-speed pulleys. The front 2 can be moved up and down on the cylinder 3, and can be rotated around the center of the cylinder to any position for processing.

4. The power equipment lifting system, circulation system and rotation system are the three major working units of the rig, which are used to provide power. They can complete the drilling operation by coordinating work. In order to provide power to these working units, the rig needs to be equipped with power equipment.The power equipment of the rig includes diesel engine, AC motor and DC motor.

How many liters does a 1.2-foot car rig consume

x0dx0a Two: Generally, the normal 2L fuel consumption is about 5-7L/100km. X0dx0a III: Dispetment, a special term for hydraulic transmission, refers to the volume of fluid inhaled or discharged per stroke or cycle. Car displacement is an important parameter to measure a car.

-7L/100km. Generally speaking, the calculation method of fuel consumption per 100 kilometers is: stage fuel consumption * 100 / stage mileage. For example, your fuel consumption is 88L*100/723km=117L/100km. It is explained here that the stage fuel consumption/stage mileage is equal to the fuel consumption/per kilometer, and multiplied by 100 is the fuel consumption/100 kilometers.

For example, Toyota Corolla uses a 2T turbocharged engine. If you drive under the comprehensive road conditions of this car, the comprehensive fuel consumption of 100 kilometers is about 6-7L. In addition, the air pressure of car tires may also affect the fuel consumption of the car.
