Digital ultrasonic flaw detector Ultrasonic flaw detector Model: JJ-CUW600

I. Overview
JJ-CUW600 Digital Ultrasonic Flaw Detector can detect, locate, evaluate and diagnose various defects in the workpiece such as cracks, welds, pores, sand holes, inclusions, and folds rapidly, easily, without damage, and is widely used in electric power. , petrochemical, boiler pressure vessels, steel structures, military industry, aerospace, railway transportation, automobiles, machinery and other fields. It is an essential instrument for the nondestructive testing industry.
Second, JJ-CUW600 digital ultrasonic flaw detector main functions ● High-precision quantitative, positioning, to meet the more recent and far distance detection requirements;
● The near-field blind area is small, meeting the requirements of small-diameter and thin-walled pipe flaw detection;
● AWS features;
● Automatic calibration: One-button automatic calibration, very convenient operation, automatic test probe "zero", "K value", "front" and the material "sound speed";
Automatically display defect echo position (depth d, level p, distance s, amplitude, equivalent dB, aperture Ñ„);
● Free to switch three scales (depth d, level p, distance s);
● Automatic gain, echo envelope, peak memory function improve the detection efficiency;
● Automatically record the flaw detection process and can perform dynamic playback; (5 minutes)
● φ value calculation: straight probe forging flaw detection, identify the highest flaw automatically converted aperture ф value;
● 300 independent inspection channels (expandable), which can freely input and store inspection standards for any industry. Field inspections do not need to carry test blocks;
● can freely store, play back 1000 A sweep waveforms and data;
● DAC, AVG, TCG curve (depth compensation) is automatically generated and can be produced in segments. The sampling point is not limited, and correction and compensation can be performed.
● Built-in 1430, 11345 and other 14 common inspection standards.
● Transmit pulse width and intensity adjustable;
● B-scan function, clearly showing the shape of the defect's vertical section ● It can freely input any industry standard;
●Communicate with computer, realize computer data management, and export inspection report of Excel format and A4 paper;
● IP65 standard aluminum-magnesium alloy shell, durable, waterproof and dustproof, excellent anti-interference ability;

● The use of PC-side communication software can upgrade the function of the instrument system;
● 260,000 true color screen super bright display, adjustable brightness, suitable for strong light, low light work environment;
● High-performance safety and environmental protection lithium battery power supply, can work for 10 hours continuously.
● Real-time clock recording: tracking records of real-time inspection date and time, and storage;
● Power-off protection, storage data is not lost;
●Flaw detection parameters can be automatically tested or preset;
● digital suppression, does not affect gain and linearity;
● Gain compensation: Db attenuation caused by factors such as surface roughness, curved surfaces, and long-distance flaw detection of thick workpieces can be corrected. 2. Important auxiliary functions of the JJ-CUW600 digital ultrasonic flaw detector:
● Two input methods: Angle and K value ● Echo frequency analysis ● Power status indication ● Gate sound and light alarm ● DAC sound and light alarm ● Freeze and thaw of the screen ● Clock display ● Hibernation and screen saver

The oil-gas Separation Filter is a device that separates the micro oil droplet to ensure that the lubrication system can work well and almost no micro oil droplet goes out of the air flow of the compressor . Applications: Solid-liquid, gas-solid, gas-liquid separation and purification in the fields of petroleum, chemical, metallurgy, aviation, electronics, power, pharmaceutical, environmental protection, atomic energy, nuclear industry, natural gas, refractory materials, fire-fighting equipment, etc.

 

The air from the compressor mains is filled with oil droplets of different sizes. Large oil droplets are easily separated by the oil-gas separation tank, while small oil droplets (suspended) must be filtered by the oil-gas separation filter. The correct choice of glass fiber diameter and thickness is an important factor to ensure the filtration effect. After the element filtered, the small oil droplets are quickly polymerized into large oil droplets, which go to the bottom of the Filter Element. These oils are returned to the lubrication system through the inlet of the return line at the bottom of the filter element, allowing the compressor to discharge relatively pure, high-quality compressed air.
