Embodiment Construction

[0015] The present invention will be further elaborated below in conjunction with the accompanying drawings and specific embodiments.

[0016] Such as figure 1 , figure 2 As shown, the test cup 6 is provided with a heater 4 and a temperature sensor 5, and the upper end of the test cup 6 communicates with a cleaning agent bottle 22, a distilled water bottle 23, a sample bottle 24, and a vacuum pump 25 through a delivery pipeline respectively. The delivery pipeline communicates with indicator bottles 9, 11, and 13, and the indicator bottles 9, 11, and 13 are respectively filled with green bromocresol, purple bromocresol, and blue bromocresol. The bottom of the test cup 6 communicates with the upper end of the test tube 17 through the delivery pipeline, and the lower parts of the test cup 6 and the test tube 17 communicate with the waste liquid bottle 30 through the delivery pipeline. Micro liquid solenoid valves 3, 2, 1, 21, 29 are respectively provided on the delivery pipeli...

Abstract

The invention belongs to the field of measurement apparatus, in particular to a fully automatic water-soluble acid tester which is characterized by comprising a test cup, a test tube, a cleaning agent bottle, a distilled water bottle, a sample bottle, a vacuum pump, a test tube, a waste liquid bottle and an indicator bottle, wherein the test cup is provided with a heater and a temperature sensor, the cup opening of the test cup is respectively communicated with the cleaning agent bottle, the distilled water bottle, the sample bottle and the vacuum pump through conveying pipes, the pipe opening of the test tube is provided with a closed needle head and is respectively communicated with the indicator bottle, the test tube and the waste liquid bottle through conveying pipes, and bottoms of the test cup and the test pipe are communicated with the waste liquid bottle through conveying pipes. The invention overcomes the defects of low efficiency and large test result error caused by adopting the manual visual colorimetry during the water soluble acid measurement of oil of a transformer and a steam turbine at present and has convenient processing and fabrication, low cost, convenient operation, stability and reliability, high working efficiency and accurate test result.

Description

technical field [0001] The invention belongs to the field of measuring instruments, in particular to a fully automatic water-soluble acid measuring instrument. Background technique [0002] At present, the known method for measuring the water-soluble acid of transformer oil and steam turbine oil is an artificial visual colorimetric method. The method is to mix and shake the same volume of distilled water and the test sample, take the water extract, add bromocresol purple or bromocresol green indicator, put it into a colorimetric glass container, and seal it in the colorimetric glass container Add the pH standard buffer solution of bromcresol purple or bromcresol green indicator, that is, carry out manual visual color comparison with the pH standard color level to determine the pH value. Due to the many steps in the whole process, involving sampling, stirring, heating, temperature measurement, cleaning, draining, etc., manual operation is inefficient and time-consuming. Duri...
