Chenda weighing: 1000g, relative accuracy, 7-level milligram group, gram group, 4 grades
Output power is not less than 0.25kW
Stir evenly and remove gas
Secondary distillation
1 group each
20ml or more
20m1 or more
Use a balance to weigh the mass of the drilling fluid cup and the cup cover, fill the cup with distillation pot, install the cup cover, wipe off the overflowed water, and then use a balance to weigh the total mass, calculate the mass of the distilled water in the cup, and convert it into capacity according to the density of water at the test environment temperature. The capacity tolerance shall not exceed the provisions of Article 4.3.
5.4 Actual relative error test of quantitative analysis 5.4.1 Determination procedure
a: Use a balance to weigh the mass of the distillation pot (including the drilling fluid cup) to an accuracy of 0.01g. 2
sY/T 5382--91
b. Use a balance to weigh the mass of the measuring tube to an accuracy of 1mg. C. Apply a thin film of high-temperature resistant silicone lubricant on the inner wall of the drilling fluid cup, pour the drilling fluid into the cup (fill it to the cup mouth), add 1 drop of defoamer, install the cup cover and rotate the cup cover to let the excess drilling fluid overflow to discharge the gas in the cup, wipe off the overflowed drilling fluid, remove the cup cover, scrape off the drilling fluid adhering to the bottom of the cup cover, put it into the cup, put the drilling fluid cup into the distillation tank, and then use a balance to weigh the mass of the distillation tank containing the drilling fluid, accurate to 0.01g. d. Place the measuring cylinder under the outlet end of the condenser. Turn on the power supply to distill the drilling fluid until the condensate stops flowing out, continue heating for 10 minutes, then cut off the power supply, wait until it cools to room temperature, and use a balance to weigh the mass of the distillation tank with solid content, accurate to 0.01g.
e. Use a balance to weigh the mass of the measuring cylinder containing the condensate, accurate to 0.01g. The difference between the values of c and a is the mass of the drilling fluid; the difference between the values of d and a is the mass of the solid phase contained in the drilling fluid; the difference between the values of e and b is the mass of the liquid phase contained in the cobalt drilling fluid. 5.4.2 Calculation of actual relative error
The actual relative error 8 is calculated as follows:
8 mo-(m+ m2 ×100%
Where: mo—mass of drilling fluid, gi
m1—mass of solid phase contained in drilling fluid, gsm2——mass of liquid phase contained in drilling fluid, g. The actual relative error 8 shall not exceed the provisions of Article 4.4. 5.5 Insulation resistance test
The insulation resistance test of the instrument shall be carried out with a 500V megohmmeter to test the insulation between the power supply head and the instrument casing.
5.6 Insulation strength test
The insulation strength test of the instrument shall be carried out with a sinusoidal alternating current with the same frequency as the power grid. The test voltage shall be 1500V. When testing, first adjust the test voltage to 400V, then increase it steadily to 1500V (no obvious instantaneous overvoltage shall occur during the increase process), maintain it for 1min, and then steadily reduce the voltage to zero to observe whether there is any breakdown or flying in the test. 5.7 Appearance inspection
The appearance and marking of the instrument shall be inspected by sense organs to meet the requirements of Articles 4.7 and 7.1. 5.8 Transport environment resistance performance test
