Organic glass is scheduled on to measure on the outer wall of tank 1；Often the spacing of infrared opposite-type detector in the vertical direction described in two adjacent groups is
10cm。
Computer 4 records the infrared signal transmitting situation of multigroup infrared opposite-type detector 2 in real time.When test ball 3 is by most
During first group of infrared opposite-type detector of upper end for the first time blocking receive infrared signal after, computer 4 will appear once receive it is different
Often, first moment is write down at this time；Stop that reception is infrared for the second time when testing ball 3 and being generated by second group of infrared opposite-type detector
After signal, computer 4 will appear primary reception exception again, write down second moment at this time；Time interval is then test ball 3 twice
The landing time between first group of infrared opposite-type detector and second group of infrared opposite-type detector；When test ball 3 passes through third
After group infrared opposite-type detector generates the infrared signal of blocking reception for the third time, computer 4 occurs once receiving exception again, at this time
Write down the third moment；Third moment and the time difference at second moment then detect for test ball 3 in second group of infrared emission
The landing time between device and third group infrared opposite-type detector；And so on, it records test ball 3 and continues to fall every adjacent
The landing time between two groups of infrared opposite-type detectors.A certain drilling fluid viscosity is surveyed using the liquid viscosity measuring device
Fixed, specific method and measuring principle are as described below：
S1, take fully enough volumes (be more than organic glass measure tank 1 volume) testing liquid add in organic glass measure tank 1
It is interior, ensure that liquid levels are higher than the horizontal plane at least 10mm for being provided with infrared opposite-type detector 2；
S2, will test ball 3 fallen into from liquid levels and free subsidence (arrow direction is under test ball 3 in Fig. 1 and Fig. 2
Fall direction)；When test 3 lower edge of ball, which is sunk down into, to be located in same horizontal line with one group of infrared opposite-type detector 2, the group is infrared
The infrared beam of line transmitter transmitting is blocked, this group of infrared receiver does not receive infrared ray in moment, at this time computer 4
It will appear first time IR signal reception exception, the time recorded at this time in computer 4 is denoted as beginning timing；Test ball 3 continues
Sink, until when test 3 lower edge of ball sinks down into and is located in same horizontal line with next group of infrared opposite-type detector 2, the group
The infrared beam of RF transmitter transmitting is blocked, this group of infrared receiver does not receive infrared ray in moment, counts at this time
Calculation machine 4 will appear second of IR signal reception exception, and the time difference for reading timing twice is △ t1；Test ball 3 continues to fall,
The time difference △ t being successively read between every two adjacent groups infrared opposite-type detector 22、△t3、…；
S3, computer 4 calculate the timing time △ t obtained by step S21、△t2、△t3... the conduct of average time t
Test the sedimentation time of ball 3；
S4, according to stoke settlement formula：
V=L/t (1)
Wherein, r is particle radius (being 3 radius of test ball here)；L is settling height；T be the average settlement time, t=
(△t1+△t2+△t3+…+△tn)/n；V is the settling velocity (cm/s) of particle；G is acceleration of gravity；D1 is the ratio of particle
Weight；D2 is liquid specific gravity；μ is liquid viscosity；κ is form factor (κ changes with shape, κ=0.222 of spheric granules).
By the average time t calculated, substitute into (1) formula；The speed v obtained is substituted into (2) formula again, it is final to calculate
Go out the viscosity of liquid system；
Finally calculating the drilling fluid viscosity is
Sedimentation of the liquid viscosity measuring device by 2 monitoring and test ball 3 of infrared opposite-type detector in testing liquid
Process, it is only necessary to launch primary test ball 3, you can it obtains repeatedly per the time difference between two adjacent groups infrared opposite-type detector 2,
And time difference average value is obtained, not only time saving result but also accurate in this way, without multiple pitching test is set to obtain the time difference again
Average value；It is measured by testing ball 3 in the infrared acquisition process used time, you can quick directly using stoke sedimentation formula
Go out the viscosity of testing liquid, time saving, less manpower, detection are accurate, safe and efficient.
Liquid viscosity measuring device described in the utility model is mainly used for the viscosity measurement of drilling fluid, while can be used for acid
Change the measurement of the pit shafts working solutions such as liquid, well killing fluid, workover fluid, it is contemplated that the corrosivity of liquid can be selected with specific reference to liquid character
It is steel ball or shot to select test ball.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model
Protection domain within.
