Although not very common in the automotive industry, gas detection imagers are a good way to visualize gases by using the physical principles of leaking gases. The imager will take a panoramic view of the scanning area and indicate the presence of a leak in the form of smoke on its viewfinder or LCD screen. The key factors for the success of optical gas imagers today are safety, efficiency, and profitability.
safety
First, the gas detection imager is a fast, non-contact measuring instrument that can be used in hard-to-reach places. It can detect small leaks a few meters away and large leaks a few hundred meters away. In this way, the operator does not need to approach the leak, which significantly improves safety.
Cost-effectiveness
Using a sniffer or probe is time-consuming, and much of the time is wasted on checking for a leak-free device. The gas detection imager can provide complete images and immediately eliminate areas that do not require any manipulation. This means huge savings in time and manpower.
Another advantage is that the system does not need to shut down the equipment during the inspection, which can save a lot of money (sometimes up to 30,000 euro per day or per device).
Improve workplace safety
Monitoring nitridation equipment
Nitriding is a heat treatment process that diffuses nitrogen to the metal surface to form a hardened surface. This process is used extensively in the automotive industry, such as gears, crankshafts and camshafts. In gas nitriding, the donor is a nitrogen-rich gas, usually ammonia (NH3). When ammonia comes into contact with a heated workpiece, it decomposes into nitrogen and hydrogen. Nitrogen then diffuses to the surface of the material to form a nitrided layer.
Although ammonia is not very toxic, it can be harmful when inhaled in large quantities. In addition, if the concentration of ammonia in the air reaches 15-15%, an explosion will occur if sparks are encountered. This is why it is very important to detect the ammonia that escapes from the gas nitriding furnace. Special optical gas imagers, such as the FLIR GF306 imager, can quickly detect and visualize these harmful gases from a safe distance without interrupting the production process.
Sealing test
For auto parts, leak detection is an important element of quality assurance testing. It can ensure that flammable, toxic or corrosive substances remain in the parts, and it can also ensure that foreign objects (such as water) cannot enter the parts. The leak test also ensures that liquids or gases that are critical to system functions such as brakes, air conditioning or hydraulic valves remain in it. There are several leak test methods to choose from, and flood detection is one of them. Although it is commonly used in many industries, flooding is not always feasible in automotive parts, especially in the case of electronic components.
Monitoring gas distribution
Optical gas imagers are also an effective method for monitoring gas distribution devices. Natural gas consists mainly of methane and ethane, both of which can be clearly detected with a medium-wave imager such as the FLIR GF320. This infrared imager can quickly scan a large area and detect leaks in real time. For the factory, this is a monitoring tool that is difficult to match with contact measurement tools.
Stainless Steel Needle Valve Hydraulic Brass
Stainless steel needle valve hydraulic brass is an important part of instrument measurement pipeline system. It mainly includes stop valve and ball valve. Its function is to open or cut off pipeline passage.
Ferrule type instrument valve has the advantages of convenient installation and disassembly, tight connection, conducive to fire prevention, explosion-proof, high pressure resistance and good sealing performance. It is an advanced connection valve in power station, oil refining, chemical plant and instrument measurement pipeline. This type of valve shall be installed horizontally in the pipeline.
Stainless steel needle valve has good sealing performance and long service life. Even if the sealing surface is damaged, it only needs to replace vulnerable parts to continue to use.
During installation, the flow direction of medium shall be consistent with the arrow on the valve body.
