Technical analysis of YWSD100/100 mine explosion-proof temperature and humidity detector
When danger comes, we are just a lamb and we have nowhere to escape. One blast of it can turn our homes built for many years into dilapidated tiles. Our real, tangible hope became a dream mirage in that moment.
We want to cry without tears, we have nowhere to go. It is insignificant in front of nature, but G+D electronic technology explosion-proof instruments can be used to reduce the occurrence of controllable disasters. Realize the vision of "perceive danger and deliver safety".
1. The YWSD100/100 mine-used intrinsically safe temperature and humidity detector controls the energy release speed of the energy storage element by adding a current-limiting circuit. At the same time, special materials are used to protect the main board to avoid the short circuit of the circuit to generate energy, thereby achieving the purpose of explosion-proof safety. .
2. The YWSD100/100 mine-used intrinsically safe temperature and humidity detector adopts an additional current limiting device to enhance the circuit safety protection system, and limit and eliminate the unsafe hidden dangers of mechanical contact ignition.
3. YWSD100/100 Mining Intrinsic Safety Temperature and Humidity Detector is a device that automatically cuts off the fuses and transistors to avoid igniting dangerous gases when the battery has over-current, short-circuit, over-voltage and other unexpected failures. To ensure the production safety of industry users and the industrial environment.
4. The housing of the YWSD100/100 mine-used intrinsically safe temperature and humidity detector has been treated with anti-static treatment to reduce surface resistance and reach international explosion-proof standards (less than 1G ohm)
5. The safety performance of explosion-proof lithium battery is higher than the national explosion-proof safety technical standard after 6,400 times without sparks. The industrial-grade YWSD100/100 mine-used intrinsically safe temperature and humidity detector adopts a highly protective 6-sided and 12-group three-dimensional frame. The shell is made of hard plastic with high strength and toughness, and is wrapped with high-density TPU for softness reduction. Shock Plastics, through high-protection technology, injection molding the two at one time, so that it has inherently strong anti-rolling performance.
Ultrasonic Drilling Rig For Geological Survey Investigation
Sonic drilling is a soil penetration technique that strongly reduces friction on the drill string and drill bit due to liquefaction, inertia effects and temporary reduction of porosity of the soil. The combination makes penetrating for a large range of soils easy for our Sonic rigs and tooling. The penetration rates in most bedrock are faster with this technology also.
At first glance, a SONIC drilling rig looks very much like a conventional air or mud rotary drill rig. The biggest difference is in the drill head, which is slightly larger than a standard rotary head. The head contains the mechanism necessary for rotary motion, as well as an oscillator, which causes a high frequency force to be superimposed on the drill string. The drill bit is physically vibrating up and down in addition to being pushed down and rotated. These three combined forces allow drilling -to proceed rapidly through most geological formations including most types of rock.
In overburden, the vibratory action causes the surrounding soil particles to fluidize, thereby allowing effortless penetration. In rock, the drill bit causes fractures at the rock face, creating rock dust and small rock particles, which facilitates advancement of the drill bit. In many instances the drilling and coring of rock and earth can be accomplished without the use of any drilling fluid whatsoever. This is an important requirement for environmental drilling projects. Compressed air, drill mud, or plain water can be utilized to remove the cuttings and speed up the operation further, depending on the application that the machine is used for.
The oscillator is driven by a hydraulic motor and uses out of balance weights to generate high sinusoidal forces that are transmitted to the drill bit. An air spring is also incorporated in order to confine the alternating forces to the drill string. The frequency can be varied to suit operation conditions and is generally between 50 and 160 hertz (cycles per second). As a comparison, ordinary household current in many countries alternates at 60 hertz. This frequency range falls within the lower range of sound vibrations that the human ear is capable of hearing.
While the principle behind the SONIC drill rig appears complicated, the machine is actually very simple to operate. The driller only adds vibratory energy to the normal rotary motion. He simply chooses a frequency that gives him the best drilling rate or best core recovery, as the case may be.
