Q:Rexroth leveling sensor rotarydrilling rig

The intake pressure sensorRole: the intake pressure sensor is to provide engine load information, that is, throughWhen the pressure of the intake pipe is measured, the intake quantity is indirectly measured into the engine, and then the intake volume is converted into an electrical signal through an internal circuit to be supplied to the computer. Failure effect: causes the engine not to start easily or the idle speed is unstable.

Q:My rotary drilling rig has broken several rotary drilling pipes. Is it my drill pipe or the reason of my rig?

Hello, this is a lot of reasons, 1. may be man-made problems, 2. can also check the machine, 3. can check the drill pipe 4., to see if the geological suitability of your choice of drilling rod

Q:What is a rotary cast in place pile?

Rotary drilling rig is the first barrel type rotary drill through the bottom valve with broken rock and soil, and directly in the drilling bucket, and then by the rig hoisting device and drill rod of the drilling bucket dumping hole is proposed, so the cycle, constantly borrow dump, until the drill to the design depth.

Q:How to distinguish the performance of rotary drilling rig?

The CAT hydraulic circuit platform, power control, power control and negative flow control by the main hydraulic circuit; auxiliary hydraulic circuit adopts load sensitive control technology is the most advanced international engineering machinery and energy saving, the load of hydraulic pump output power and the moving parts of the optimum matching, improves the work efficiency and controllability.

Q:How can the drilling rod of rotary drilling rig be telescopic?

It extends in the first order, the next second, and then the third, the last, the fourth, and the fifth. During drilling, it is stretched by gravity and bit by bit with the drilling depth. Rotary drilling rig in the multi-functional areas to improve, and it is not necessary to complex conversion can be converted to another device, it is worth studying.

Q:Rotarydiggingmachine life

Article sixtieth of the regulations on the implementation of the enterprise income tax law, in addition to the provisions of the financial and tax authorities under the State Council, the minimum amount of depreciation for fixed assets shall be as follows:(a) housing and buildings for 20 years;(two) aircraft, trains, ships, machinery, machinery and other production equipment for 10 years;(three) appliances, tools, furniture and so on related to the production and operation activities, for 5 years;(four) aircraft, trains, ships and other means of transport for 4 years;

Q:Construction steps of rotary drilling rig

The soil sand in the dump in earthmoving vehicles or on the ground to shut the valve back drill, rotary drilling rig rotary drilling rig rotary lock body, put down the drill, drilling, hole cleaning and determination of depth, into the steel reinforcement cage and concrete pouring, catheter, pull out tube and clean up the pile head sink silt backfill pile.

Q:Types of rotary drilling rig

The principle of choosing a rotary drilling rig should be to meet the major engineering requirements of the user and take into account the possible engineering requirements. Rotary drilling rig can be divided into three types according to its main working parameters: torque, engine power, drilling diameter, drilling depth and the quality of drilling rig:Torque 100kN = M. The power of the motor is 170kW, the drilling hole diameter is 0.5 to 1m, the drilling depth is about 40m, and the quality of the drilling machine is about 40T. Application market positioning of minicomputer:

Q:How can the drill pipe cracking of rotary drilling rig be welded?

Or very good welding, and see what the substrate material. The shaft fracture can be welded. Tianjin source welding can be consulted.

Q:What are the reasons for partial drilling of rotary drilling machine?

Drilling bucket: the main function of drilling bucket is cutting and drilling, but it also has the function of guiding and preventing deviation. The pilot base drilling bucket with positioning function, at the same time the pilot pointed tip can be changed into order, and the number of teeth of the drill view is not common, the drill body on both sides of the knife or door bar height is not common, these details can make drilling bucket drilling about uniform stress and prevent error.
