Transformer oil acid tester is a fully automatic measuring instrument which adopts the extraction method to accurately detect the insulating oil acid value. This instrument can improve the working efficiency and test accuracy, and at the same time ensure the safety of the body by reducing the operator's contact with the samples and reagents.
The acid value is the trace value of potassium sulfate that neutralizes the petroleum acid in 1g of oil, which contains a certain amount of inorganic acid and inorganic acid. The acid value includes organic and inorganic acids contained in the oil. In most cases, oil does not contain mineral acids. Therefore, the oleic acid value actually represents the content of organic acids in the oil. The organic acid contained in the new oil is mainly cyclonic acid. In the oil and in the process of use, the acid value of the oil produced by oxidation is an indicator to measure the degree of refining of the new oil. Whether the oil is running is an important indicator of the continued use of oil quality equipment.
Mould Oscillation and Deflection Detection Instrument
Overview
The mold is a device that shapes the cast product in continuous steel casting, and it is also the core equipment and key technology of continuous casting machine. The main function of the mould oscillation deflection detection instrument is to detect the the mould oscillation table s oscillation frequency, amplitude, deflection rate, phase, oscillation trajectory curve, etc. Through the detection and adjustment of the detection instrument, the mold moves along the outer arc of the continuous casting machine according to the given amplitude, frequency and waveform deflection characteristics.
The actual oscillation parameters of the mold oscillation table during the operation and production process and the process parameters of the cast products cannot be effectively known without the data detection of the mold deflection detection instrument, so that the operator cannot adjust the mould s production process parameters in real time according to the real-time situation of the on-site production.
The continuous casting mold deflection detection instrument independently developed by our company is suitable for various molds such as slab, square billet, round billet and shaped billet. The system obtains the process parameters such as actual oscillation holographic parameters and negative slip amount of the oscillation table by effectively detecting the movement of the mold. The technicians can formulate the control strategy of the mould according to these actual parameters, and improve the output and quality of the product within a safe and reliable range.
The structure of the instrument
Continuous casting mold oscillation and deflection detection instrument is mainly composed of sensor system, sensor signal conditioning circuit, power supply circuit, synchronous data acquisition module, communication cable, and software data analysis system.
There are three axial acceleration sensors installed in the mold oscillation and deflection detection instrument, one of which is to detect the vertical oscillation signal (Y axis), and the other two are to detect the horizontal oscillation signal (X and Z axis). The signal obtained by the sensor is processed by the preprocessor and the preprocessing module. The oscillation signal and sensor status signal will be filtered and normalized, sent to the synchronous data collector for digitization and feature extraction, and the data is analyzed and processed by the master computer software to obtain various oscillation parameters and process parameters required by users.
