All of them are used, but they are relatively few, and our inverters are used on pile drivers, mainly on the torque. Transformed.
-
It should be possible to install an inverter air conditioner, which can be installed by modification.
-
Of course, the eight stunts can be installed, the inverter air conditioner, as long as your way is right, and then the voltage can be carried out, and the one that broke the special air conditioner.
-
The excavator can be equipped with inverter air conditioning, because the inverter air conditioner is still relatively convenient to use, and it can be used under some other safety voltages, such as from 5 volts to 72 volts.
-
Of course, the rotary excavator can be equipped with an inverter air conditioner.
However, loaded. Inverter air conditioning.
I can't afford the battery inside the excavator.
-
The rotary drilling rig should be able to install and change the air conditioner, and the performance is also very good, so that it should be able to use the temperature better.
-
There should be no rotary digging transfer machine, and there is no inverter air conditioner, so it is more luxurious if it is installed.
-
It is best not to install an inverter air conditioner for rotary digging transfer.
-
Generally, it does not use electricity, and uses the gasoline engine power of the drilling rig itself.
When buying a rotary drilling rig, you can ask for dual power, then you can use electricity, the construction site drilling rig drags two wires is electricity, a mud pipe, one is a cable.
-
Many don't use it, burn diesel, and Sany spin digs diesel-electric hybrid
-
Generally, no electricity is used, and the diesel engine power of the drilling rig itself is used.
-
If you don't use electricity, you rely on hydraulic oil.

Rotary drilling rigs can adapt to the corresponding geology according to different models and brands. Generally used:
Backfill layer, silt layer (pay attention to the specific gravity of mud), clay layer, sub-clay layer, sand layer, gravel layer (the particle size of gravel is limited), gravel layer (the particle size of gravel is limited), and the micro-weathering layer.
There are also three ways to make your rotary drilling rig suitable for various geological constructions.
The first trick is to change the pressurization method according to the load and **.
1. When carrying out soft soil operations, because of the light load, after large flow output, it can be pressurized drilling at high speed.
2. When carrying out clay layer operation, it must be continuously pressurized to ensure that the high speed and low load drilling.
3. The most annoying thing is the sand layer with relatively large friction, and you must keep pressurizing and returning to pressure, otherwise you will have to work for at least 3 hours, not to mention the wear and tear of your machine.
4. When you encounter oscillating geology with high precision, you must have the momentum of the brave winning when you meet on a narrow road, and constantly press and force it to break.
The second trick is to control the speed of the drill pipe through the soft and hard strength and category of the geology.
1. Don't underestimate the pebble layer, you have to remember it when you are working, avoid the hardness spearhead, use slow speed drilling, and the work efficiency is a word - high.
2. If your temperament is more urgent, when working in a stable mudstone and a hard gravel layer, you must be patient, at the beginning I had no experience, so I wanted to hit the nail on the head, and finally I didn't expect to slip all the time, I was quite depressed at the time, and then I found out when I drilled at a low speed, it turned out to be so easy.
3. Those who have experienced the bottom layer of gravel know that breaking the side teeth is a small thing, when working at high speed in the gravel layer, you will hear a bang, and the drill pipe is almost torn, in this case, you must drill at medium speed, otherwise what awaits you will be a bloody lesson.
4. In a stable bottom operation, you don't have to worry, high-speed drilling, no problem. The rotary drilling rig is equipped with down-the-hole hammer drilling tools, which are powered by compressed air during construction, and the impact energy and impact frequency generated are directly transmitted to the hammer head, which quickly crushes the rock within the diameter of the pile hole and then pours it into piles.
The third trick is to adjust the engine speed well, which is energy-saving and efficient.
This point needs to be controlled by the machine friends, because the load of each project is not the same, and the action of each machine is also different, so remember to adjust the speed of the engine, so as to be more energy-saving and more efficient to complete the task.
If you have this need, you can go to Infinity.

Rotary drilling rig is a kind of construction machinery suitable for hole forming operations in building foundation engineering. It is mainly suitable for the construction of sandy soil, cohesive soil, silty soil and other soil layers, and has been widely used in the construction of various foundations such as cast-in-place piles, diaphragm walls, and foundation reinforcement.
The rated power of the rotary drilling rig is generally 125 450kw, the power output torque is 120 400kn·m, the maximum hole diameter can reach, and the maximum hole depth is 60 90m, which can meet the requirements of various large-scale foundation construction.
Special equipment refers to boilers, pressure vessels (including gas cylinders, the same below), pressure pipelines, elevators, lifting machinery, passenger cableways, large-scale amusement facilities and special motor vehicles in the field (factory) that involve life safety and are more dangerous.
Among them, boilers, pressure vessels (including gas cylinders), and pressure pipelines are special pressure-bearing equipment; Elevators, lifting machinery, passenger ropeways, and large-scale amusement facilities are special mechanical and electrical equipment.

It is not a special equipment that belongs to piling machinery.
Piling machinery: In various pile foundation construction, the machinery used for drilling, piling, and pile sinking is collectively referred to as piling machinery. Piling machinery is generally composed of two parts: pile hammer and pile frame.
In addition to the special pile frame, the pile frame can also be set on the excavator or one of its machines to complete the piling task. The main characteristics of piling machinery are strong specificity and small production batches.

It is not a special equipment that belongs to piling machinery.
-
No, because of the outside! The rock is relatively hard, and the rotary drilling rig is suitable for evacuation formation.
-
Small models are generally not good, and large torque ones are okay for not too hard rocks. Rotary drilling rigs are suitable for evacuating formations.
-
The rock layer depends on the hardness, I have seen 280 drilling rigs have hit 700kpa of mudstone and 2200kpa of granite, and 250 drilling rigs have beaten 4000kpa of schist, rotary drilling rigs can hit the key to the rock is the construction method, and the speed of hitting the rock is also very slow.
-
Directly open the drilling rig, because there are a lot of skills in the operation of the rotary drilling rig, such as what formation with how much footage speed, these can not be learned in books, only practice can master the skills, my unit of rotary digging drivers are masters, into holes, fast, monthly wages are about 10,005.

Maintenance and machine operator are two very different types of work, and the path forward is very different. Maintenance is a technical work, divided into machine repair, hydraulics, circuit three major blocks, it is not difficult to learn the same, it is difficult to master all and be proficient in various models, want to learn to go to the repair shop, to the master is willing to teach. If you learn well, you can work with the repair shop, and if you learn well, you can do it yourself.
Although the operator is also a technical job, the emphasis is on the accumulation of experience. The operation of the machine is very simple, and there is not much difference between different machines, it will be very quick to get started, and it will take a few months to be familiar with the operation. However, it is necessary to be proficient in the construction methods of various strata, which is as fast as one and a half years and as slow as three years.
This job has to be away all year round, if you have no money and no connections, you will work for the rest of your life, but the salary is not bad. If you can make your own connections, it will be completely different to buy equipment and be the boss of the construction site in the future.

Rotary drilling rigs are basically taking soil positive circulation, why must use reverse circulation, process requirements, rotary digging into holes can be used conduit to do reverse circulation hole cleaning.
1. Lofting positioning.
Before the start of the project, according to the axis and pile layout, a measurement and control network is established in the site, and then the center point of each pile position is measured and released according to the control network. >>>More
The first is to pay attention to safety, safety first.
The pile foundation is the main load-bearing part of the structure, and its quality is directly related to the safety and longevity of the structure, so the pile foundation is detected. >>>More
Let's put it this way. Basically, there is nothing that can be solved. >>>More
After the launch of the <> Hongmeng operating system, it is difficult to get a large area of promotion by relying on Huawei's own model adaptation alone, so it is likely to adopt the "open source" method, so many flashing enthusiasts can compile various ROMs according to different platforms according to the open source **, that is, most Android mobile phones can experience the "Hongmeng" operating system through "flashing". >>>More
