generally L6 and L8, these two kinds are down the hole drills
and D7, which is more famous, is a top hammer type

which integrates down the hole and hammer. I really haven't heard that
is totally two different drilling methods, how to integrate them?

2. Atlas was founded in 1919 with a long history and excellent quality. The world's first full hydraulic excavator was proced by atlas in 1950. It is one of the top brands of hydraulic excavators in Europe. In early 2004, Atlas established the first atlas hydraulic excavator proction line in Asia with a joint venture with China to proce 20 ton to 33 ton hydraulic excavators. Atlas hydraulic excavator features: first, advanced performance, unique technology; 2、 High power and low fuel consumption; 3、 Atlas hydraulic excavator design features: Engine: Atlas Series Hydraulic excavators are all equipped with DEUTZ high-pressure fuel injection engine system with water-cooled intercooler. The engine has withstood the test of severe working conditions in Europe. It has the characteristics of high fuel efficiency, fuel saving, long service life and high reliability. The engine output power and engine speed are controlled by the electronic control system, and the emission reaches the European class II standard
control system: awe6 electronic control system is adopted, with functions of overload protection, power mode conversion, automatic shift, overheat protection and fault diagnosis. Hydraulic system: it adopts German Linde LSC (load sensing synchronous control) hydraulic system, uses load sensing swashplate piston variable pump and closed core load sensing valve, which can continuously sense when working, and adjust the flow of hydraulic oil according to the working needs of the system, so as to make the overflow energy loss of hydraulic oil close to zero, and effectively control the fuel volume, And minimize the heat of the hydraulic oil, so that its temperature control in a certain temperature range, so that the machine can quickly enter the best working condition and work for a long time, improve the work efficiency. Under special circumstances, if the temperature of the hydraulic oil exceeds the operating standard temperature, the system will automatically warn the operator to stop the machine, so as to protect the hydraulic system of the excavator from damage and prolong the service life of the machine. The latest load sensing valve has very high precision hydraulic oil flow control ability, and can provide up to four different operation actions at the same time, which is not affected by the load of a certain action of the excavator
cooling system: some models use the radiator driven by Linde hydraulic system, and are equipped with temperature sensor and radiator speed control valve. According to the temperature of the hydraulic oil to determine the circulation mode of the hydraulic system, in order to ensure the effective control of the hydraulic oil temperature in the normal working temperature range, to maximize the efficiency of the hydraulic oil, energy loss to the minimum
Travel System: four wheel belt without maintenance (roller, chain wheel, driving wheel, guide wheel and crawler). Because it is difficult to maintain the four wheel belt, once it is damaged, the cost of repair and replacement is very high, so it is free of worries for users 2) Walking two speed automatic adjustment and manual shift: for example, when walking in the high gear state, when encountering climbing or increasing resistance, the system will automatically switch to the low gear to protect the walking device. When the driving resistance is reced, the system will automatically switch to the high gear to avoid the cumbersome manual speed control and increase the safety performance 3) It is the only one in China that uses single operating lever to control 8 directions of walking, and can use foot pedal to control forward and backward at the same time
slewing system: Linde slewing motor (integrated with directional control valve) is adopted, which has the characteristics of large displacement, fast slewing acceleration and flexible braking, and there is no overflow loss in slewing, effectively saving energy. Internal use of long-life self-lubricating bearings and hydraulic motor, gearbox and brake common lubrication system. The cab is equipped with a slewing locking brake pedal, which can lock the slewing device when uphill to ensure driving safety
steel: high quality steel is used in the whole vehicle, and high-strength steel plate is used in important parts, which can resist high-strength load. Specially designed heavy-ty X-type extended frame, more rable. The boom is reinforced with multi-layer thick plate in high stress area, which can resist strong impact force. The pin shaft processed by nitriding process has higher strength and longer service life
centralized automatic lubrication system of the whole machine (optional): users only need to inject special lubricating grease into the lubrication system, and the device will automatically and irregularly inject grease into various parts that need to be lubricated according to needs, without manual filling. Safety features: (1) machine system safety: the boom is equipped with hydraulic pipeline explosion-proof device, which can automatically stop the boom activity after the hydraulic pipe burst, so as to protect the mechanical safety 2) Cab: the cab conforms to European and American labor safety protection standards, and the cab glass has anti ultraviolet function
overall operation characteristics of atlas excavator: when the excavator system is working, the hydraulic pressure required for excavation is transmitted to awe6 electronic control mole through pressure sensors installed in various parts of the system, which controls the opening and closing angle of the swash plate in the hydraulic pump to adjust the real-time output flow of the hydraulic pump, Then according to the existing flow of the hydraulic pump to adjust the output power of the engine, so as to achieve the purpose of fuel saving. When working, the electronic control system monitors the working condition of the system in real time through the signal sent by the sensor, and is equipped with overload alarm and hydraulic oil temperature alarm indication to inform the driver of the working condition of the system, so as to make corresponding response, so as to ensure the normal use of the machine system and prolong the service life

3. First of all, the definition of gambling should be determined. From a wide perspective, gambling is a kind of game that takes valuable things as a bet to win or lose. It is a way of entertainment for human beings. Therefore, all games linked to money can be gambling. If so, futures trading for the purpose of speculation is gambling. Buying stocks for the purpose of selling is also gambling. It can even be said that most investments can be regarded as gambling

excluding such a broad concept, futures and gambling actually have a huge difference. First of all, gambling pays attention to buying and leaving. Once it is decided to bet, it can not be reversed, and the final outcome has been doomed. But futures are different. Whether futures investment profits change with the time and price of the position. Author online guidance_ Qkcs918, in futures operation,
secondly, futures are more technical, and the analysis of fundamentals and market conditions is more important, while gambling is relatively simple, and luck is more important
finally, the biggest difference between the two is that gambling is illegal, but the State supports and protects legal spot and futures investment. There are strict laws and regulations for futures procts and related businesses that are not yet open in China, so we suggest that you choose legal and compliant investment procts.

4. It depends on you. If you go in with the mentality of making big money and quick money, chasing up and killing down, it's definitely gambling, and the probability of losing is far greater than the probability of winning
if you take this as a capital investment, it's not gambling.

5. I can't understand that! Gambling is illegal, but futures are legal, which is the most important difference. Futures are determined according to the price of bulk commodities in the market, which will be affected by the changes of international economic environment, political situation and geopolitics. So this is essentially different from gambling, but futures can be traded with leverage, which has amplification effect and great risk!

The static capacitance keyboard is more stable, more sensitive and has longer service life than the mechanical keyboard

The trigger principle of the static capacitance keyboard is to use the change of the capacitance to judge whether the key is on or off. After pressing the key, the capacitance in the switch changes to realize the trigger. The whole process does not need to close the switch, and can realize the knock without relying on the physical contact point

2. There is a separate switch under each key of the mechanical keyboard, which is triggered physically by the key

extended data:

about the mechanism of the static capacitance keyboard:

spring structure:

the traditional static capacitance keyboard has a rubber bowl like structure inside, which is similar to the membrane keyboard, but it does not support the keys like the membrane keyboard, and the supporting function is actually the internal conical spring

since the key is supported by a spring, the pressure of the key can be adjusted by adjusting the spring force, which is another feature of the traditional static capacitance keyboard: partition pressure

diamond sleeve structure:

"Diamond sleeve" is a sleeve on the crater structure, using self-lubricating POM material. The friction coefficient of this material is small, which is only one tenth of that of ABS or hips materials with traditional crater structure. Therefore, users do not need oil lubrication, long-term use of the oil will not be dry, and the card key and other issues, to ensure the stability and accuracy of the key

Static capacitance keyboard and mechanical keyboard have the following differences:

1. Keyboard trigger principle is different

1. Static capacitance keyboard: use the change of capacitance capacity to judge whether the key is on or off. After pressing the key, the capacitance capacity in the switch changes to realize the trigger. The whole process does not need to close the switch, and it can be knocked without relying on the physical contact point

2. Mechanical keyboard: there is a separate switch under each key, which is also called "axis", and the switch is triggered physically by the key

Second, the best application direction of the difference

1, static capacitance keyboard feel light, smooth input, labor-saving. Suitable for users who need to use a lot of keyboard, such as typists, programmers and so on

2. Mechanical keyboard is usually used as an expensive high-end game peripheral because each key is composed of an independent micro motion, so it has a strong sense of paragraph, which is suitable for game entertainment

The static capacitance keyboard generates electrical signal through the change of the distance between the two ends of the capacitor. In other words, the static capacitance keyboard keys will not hit the bottom board, so the noise problem is solved

2. The mechanical keyboard makes a high-frequency click sound every time it is knocked because of its shaft body paragraph type design
