Plasma Cutting Machine

Plasma Cutting Machine 

What are CNC Plasma Cutting Machines? 

Plasma cutting is a process that cuts through electrically conductive materials by means of an accelerated jet of hot plasma. Typical materials cut with a plasma torch include steel, Stainless steel, aluminum, brass and copper, although other conductive metals may be cut as well. Plasma cutting is often used in fabrication shops, automotive repair and restoration, industrial construction, and salvage and scrapping operations. Due to the high speed and precision cuts combined with low غير مجاز مي باشدt, plasma cutting sees widespread use from large-scale industrial CNC applications down to small hobbyist shops. CNC cutting machines, such as CNC plasma cutting machines, utilize their intricate software systems and components to efficiently, accurately and smoothly handle plasma cutting processes. 

CNC Plasma Cutting vs. Other Cutting Methods: 

Of course, plasma cutting is only one variety of system which CNC machines may be designed to work with. Another common variety is the CNC waterjet cutter. Waterjets can use either a mixture of pressurized water and abrasive, or purely water. One benefit to a waterjet cutter is that there`s no HAZ, or heat-affected zone, which can alter a material.

Another cutting method utilizing CNC machines is oxy-fuel, using fuel gases and oxygen, which dates back about 100 years. Here, a stream of oxygen is blasted onto a metal heated to kindling temperature, turning it into a flowing metal oxide.

With CNC plasma cutting machines, a plasma torch blows an inert gas at high speeds out of a nozzle, through an electrical arc, which turns some of that gas to plasma.

While all of these options remain widely used today, CNC plasma cutting machines are typically seen as a solution for manufacturers who are concerned with quickly and efficiently cutting conductive materials up to 3″ thick. The CNC plasma cutting process has superior cutting speeds, piercing speeds, and generates very precise cut qualities. More speed and higher quality also produces superior efficiency and productivity. 

CNC plasma cutting machine applications:

It is widely used in the process of cutting metal plates in the machinery manufacturing industry, engineering industry and metal fabrication and can cut mild steel, stainless steel, aluminium, copper and many kinds of non-ferrous metal.

[China Instrument Network Instrumentation Enterprise] Speaking of today's PLC RF LoRa, Xiaobian first took you back to review EnVerv. EnVerv entered the Chinese market 4 or 5 years ago. After that, they also established a cooperative relationship with some well-known domestic meter companies to seek opportunities for the development of 4G PLC technology in China's smart grid and smart metering markets. I do not know whether it is too late to wait for verification of the sample, or the threshold of the Chinese market is indeed not easy to tread, and slowly, this company faded out of people's vision.

Since the beginning of last year, LoRa technology has received more and more attention in the meter circle, especially in the water and gas industry. After that, everyone knows that this company called Semtech leads the way in high-quality analog and mixed-signal semiconductor products. supplier. As the initiator of the LoRa Alliance, there have been reports from the media, which mentioned that ZTE Microelectronics and Semtech and more than 20 cooperative manufacturers have jointly established the China LoRa application cooperation eغير مجاز مي باشدystem and are committed to promoting LoRa technology and building low-level skills. Consumables are deployed and applied to special networks to jointly serve the construction of smart cities. Several of them are from the metering industry, such as China.

Then in January 2015, Semtech acquired EnVerv.

The above is the background.

[Chinese instrument network meter patent] creative limit, instrumentation invention. Today, we introduce a national patent for invention invention - ultrasonic IC card water meter and heat meter. The patent was applied for by Hunan Changde Brand Water Meter Manufacturing Co., Ltd., and was authorized to be announced on May 4, 2016.

Description of the Invention The invention pertains to tap water meters and thermal energy meters, in particular to an ultrasonic IC card water meter and thermal energy meter.

BACKGROUND OF THE INVENTION Currently, IC cards water meters and heat energy meters used in various places generally adopt a water flow to push the impeller to perform a mechanical rotation and an ultrasonic wave to measure a water flow velocity. Water meters are more mechanical, while thermal energy meters use ultrasonic waves to measure water velocity. Because of mechanical problems such as the wear of impellers and other rotating parts, their service life is relatively short. Ultrasonic measurement of water velocity has the advantage of long life.

The current method of measuring the flow velocity of ultrasonic waves for water meters and thermal energy meters is divided into ultrasonic direct reflection and reflection. Since the reflection type needs to fix one or two reflection surfaces in the ultrasonic path, these reflection surfaces are easily contaminated. Reducing reflectivity, so it is more common to use direct methods to do ultrasonic water meters and heat meters.

At present, most of the water meters and heat energy meters made by using direct ultrasonic waves are equipped with ultrasonic transducers installed on both sides of the velocity measuring tube, so that the ultrasonic wave propagation path has a certain angle with respect to the flow path of water. The influence of the ultrasonic wave on the water flow will only have the effect of the same component as the ultrasonic wave propagation direction, thus reducing the amplitude of the ultrasonic waves being affected by the water flow. This means that this method reduces the accuracy and sensitivity of the ultrasonic flow velocity measurement.

In addition, the current ultrasonic water meters and heat energy meters, the majority of the use of the flow velocity tube diameter and the nominal diameter of the table is basically the same, so that the water velocity in the flow velocity tube can not be improved, but also to reduce the accuracy of the flow velocity measurement One of the reasons for sensitivity. At the same time, most of the flow velocity tubes are made of metal materials and the surface is rough, which also has a certain influence on the uniformity of water flow.

In addition, most current transducer holders made of metal or plastic are used to fix and seal the ultrasonic piezoelectric ceramics, and these transducer holders cannot effectively prevent scale formation on the surface and collect rust in the water. Therefore, the surface of the transducer is easily fouled and loses its normal transmission and reception of ultrasonic waves.

Another is that most of the ultrasonic water meters and heat meters currently connected to the signal line of the ultrasonic transducer and temperature sensor are exposed outside the case, so that they can easily be destroyed by humans or accidentally, causing them to lose their normal measurement function. .

The first step of the initial jacking is to break the hole. Before the hydraulic jacking machine breaks the hole, the hole must have measures to prevent the collapse of the soil or sand layer. When the hydraulic pipe jacking machine jacks into the uniform earth loess, generally the hole is sealed with bricks; however, in the sand, it is more effective to adopt deep mixing piles and high-pressure rotary spraying.

Hydraulic jacking machine jacking machine initial jacking The second step is to let the jacking machine into the soil, when the closed door is removed, the jacking machine cutter can start, with the main fuel tank slowly push the jacking machine into the soil. In the process of hydraulic jacking machine, care should be taken to prevent the cutter head from being embedded in the sand and not to rotate the jacking machine housing.
