1. How far is the wireless receiving distance of the detector? With the continuous development of drilling production, the use conditions of drilling rigs have become more and more diversified, and various types of drilling rigs have appeared accordingly. Factors affecting the type and composition of drilling rigs include drilling method, drilling depth, borehole size and drilling tool size, and drilling area conditions (such as electricity or fuel, transportation, and meteorological conditions).

Barrier-free distance is 300 meters.
2. How long can the backup battery in the host support?
Various models are different, ranging from 5 to 24 hours. The on-site alarm system has no backup battery.
3. How long can the door sensor and probe batteries last?
First of all, depending on the quality of the battery, it can be triggered about 30,000 times.
4. How do I know it's time to replace the battery?
When the power is insufficient, the indicator lights on the door sensor and the probe will flash continuously.
5. Will the infrared probe produce radiation to the human body?
The infrared probe is detected by infrared rays, and does not emit any radiation by itself.
6. What is the detection range of the probe?
The detection distance is 8-10 meters. The detection range of individual detectors is different. For details, see the instruction manual.
7. Are there any emergency measures if the remote control is lost?
Temporarily arm and disarm via phone, and then add (login) again.
8. What should I do if the phone dialed during the alarm is busy?
The alarm will automatically dial multiple sets of calls, and there will never be a call that wo n’t work.
9. Will small animals cause false alarms?
Little King Kong is pet-proof.
10. If the window is not closed, will the alarm work?
The door sensor will fail, but the probe can work as usual, so it is best to use double protection of door sensor and probe.
11. Doesn't it need to install door magnet when the probe is installed?
The function of the door sensor is to alarm immediately when the door and window are opened, and the function of the probe is to alarm when a person attempts to enter the room.
12. Why does the probe sometimes fail to respond?
The probe adopts a power-saving design. It takes 10 seconds to 5 minutes after each trigger to respond to the second trigger.
13. How to fortify when sleeping at night?
You can choose a host that can be partitioned for arming.
14. Will smoking trigger the smoke detector?
No, it will only trigger when the smoke reaches a certain concentration.
15. Will the alarm system produce false alarms or omissions?
In theory, there may be false alarms in the alarm system. The Ministry of Public Security allows a certain false alarm rate in the alarm system. The false alarms are mainly due to infrared probes. There is no problem of false alarms on the door sensor and the host, so when installing the infrared probe, we should install it in strict accordance with the regulations to minimize the false alarm rate.
The alarm system does not allow missing reports. In order for the alarm system to work well, please pay attention to whether there is electricity in each detector. If a weak current indication appears, please replace the battery in time.
16. Will other people's detectors interfere with my alarm? Can someone else's remote control control my home alarm?
Don't worry, because each detector and remote control have different codes.
17. Can a thief who is familiar with this system remove the alarm and then steal?
First, the system is installed indoors and cannot be removed without entering the room. Secondly, the door sensor and probe will alarm when they are dismantled. Again, even if the door sensor and probe are destroyed, the alarm will not stop.
18. Does the manufacturer have a solution?
Theoretically, it can be cracked, just like a set of combination locks, one by one, but the workload is huge.
1. According to drilling method
(1) Impact drilling rigs, such as wire rope impact drilling rigs (drilling rigs), vibration drilling rigs, etc.
(2) Rotary drilling rigs, such as those used in rotary drilling.
(3) Downhole power drilling tools, such as rotary drilling tools, turbo drilling tools, screw drilling tools, electric drilling tools, etc.
2. Divided by drilling depth
(1) Ultra-deep well drilling rig. It adopts a drilling rig with a diameter of 114 mm drill pipe, a nominal drilling depth range of more than 7000 meters, and a maximum hook load of more than 4,500 kN.
(2) Deep well drilling rig. The drill rod is 114 mm in diameter, the nominal drilling depth is 4000-7000 meters or more, and the maximum hook load is 2250-4500 kN or more.
(3) Drilling rigs for medium and deep wells. It adopts a drilling rig with a diameter of 114 mm drill pipe, a nominal drilling depth range of 1500-4000 meters or more, and a maximum hook load of 900-2250 kN or more.
Three, according to power equipment
(1) Diesel Engine-driven drilling rigs, which use diesel engines as power through mechanical transmission or hydraulic transmission.
(2) AC driven drilling rig, suitable for use in oil fields with industrial power grids.
(3) The drilling rig is driven by direct current, and the working unit is driven by a direct current motor.
Fourth, according to the driving mode
(1) Drive alone. Each working machine is driven by generators of different sizes, which are mostly used for electric drive. The transmission is simple and easy to install, but the power utilization rate is low and the total equipment mass is large.
(2) Unified drive. The three working units of drawworks, drilling Pump and turntable are driven by the same power unit. Most drilling rigs use this scheme. The unified drive can also include only one drilling pump, and the other drilling pump is driven separately. The unified drive drilling rig has high power utilization and can be adjusted mutually when the engine fails, but the transmission is complicated, installation and adjustment are troublesome, and the transmission efficiency is low.
(3) Group drive. The combination of power is between individual drive and unified drive. There are two options for three working machines. The power utilization rate of this kind of drilling rig is higher than that of a single drive, and the transmission ratio is simple to drive in a unified manner. Two sets of working machines can also be installed on different heights and scattered sites.
