Carbon Sulfur Analyzer Overview

The carbon-sulfur combined analyzer is a new generation of steel analysis instrument developed on the basis of mature technology based on the national standard gas volume method and iodometric method using advanced sensing technology. Used for the quantitative analysis of carbon and sulfur in steel, iron and other materials. The carbon content method was used for carbon measurement, and the iodometric method was used for sulfur measurement.

The carbon-sulfur combined measuring analyzer adopts a precise sensor to realize the digital display of the measurement results, read the content directly, and can automatically print the test results, overcoming the visual errors and conversion errors that cannot be overcome in the previous gas readings, and improving the measurement accuracy. The control circuit adopts advanced single-chip technology and works with Darlington-driven solenoid valves. Oxygen, which is essential for various combustion furnaces, is used as a power source to basically achieve non-contact operation of the control process.

The carbon-sulfur combined analyzer test process was automated, and the fluids in the grid were absorbed. The calibration was performed using the standard line quality (abbreviated as standard sample) and the digital display was read directly. The influence of barometric temperature is overcome by the standard sample reference, no conversion is needed, and the measurement speed and precision are greatly improved. Carbon-sulfur combined analyzers can be used with arc burners and can also be used with other types of burners, such as tube furnaces and high frequency induction furnaces. QR-4 carbon-sulfur analyzer adopts the principle of Chinese national standard measurement (carbon gas volume method, sulfur using iodometric method). It is equipped with an electronic balance to achieve indefinite sample measurement, and touch-type membrane button full Chinese menu operation. , And can store four working curves, test results of large-screen liquid crystal display and print directly, carbon can be displayed to three decimal places, sulfur can be displayed to four decimal places, its accuracy is better than the Chinese national standard.

Bearing rings: Dimension tolerance, geometric tolerances, and surface quality of bearing` s working surface will influent the operating noise. Naimei Bearing adopts precision CNC machining to dimension precision,  geometric tolerances, design drawing, mold making, grinding, cleaning,  assembly, testing, every link of strict checks, so as to ensure all our products are tested by our strict criteria.

Balls:  The balls evenly with by the cage, often make rolling movement between 2 rings. The shape, size and number will directly influent bearing`s load tolerance and operating capability. We use high precision, small vibration steel ball. It`s surface must be strengthened, no bumps scratches, lacerations, pitting and notch.

Cage: Enclose and move with all or part of the balls. It also be used to insulate the balls, guide the balls` movement and to improve lubrication performance inside the bearing., etc. Naimei Bearing`s cage is commonly made of cold rolling carbon steel. But in the corrosiveness environment, nonparallel or high-speed situation, stainless steel, engineering plastics cagecan be decided on request.

Seal: Naimei Bearing adopts different kind of seal material to meet the requirement of their operating in high temperature and being compatible with grease. Acrylonitrile-butadiene rubber is our standard material. but in high temperature environment ,often adopt fluorocarbons, silicone , PTFE shield.
