Fig. 1 is front view of the present invention.
Fig. 2 is longitudinal sectional view of the present invention.
Fig. 3 is the structural representation of capillary tube of the present invention and liquid cabin connecting portion.
Fig. 4 is the structural representation of hollow plastic pipe of the present invention through liquid cabin.
Detailed description of the invention
As depicted in figs. 1 and 2, differential depth of mud tester of the present invention mainly comprises: semi-enclosed housing 10, liquid cabin 4, capillary tube 5, differential pressure pickup 6, data processing equipment 3, display unit 1 and electric supply installation 2.
Wherein, liquid cabin 4 goes up interval along its length and arranges, and capillary tube 5 connects between liquid cabin, and differential pressure pickup 6 is positioned on capillary tube, for measuring capillary overpressure.Data processing equipment 3 is arranged at and is installed in housing and is electrically connected with differential pressure pickup, and display unit 1 is electrically connected with described data processing equipment, and electric supply installation 2 is powered for above-mentioned part or all of power device.
In this embodiment, liquid cabin has certain interval, when it is arranged in different liquid or colloid, pressure differential between it can change, how pressure differential numerical value exceedes set threshold value, then think the interface reaching mud and cement colloid, thus reminds engineers and technicians.Now be the degree of depth of mud from liquid level to the distance of below liquid cabin.Therefore, the present invention is more more accurate than prior art, and operation is also very simple.
In a further embodiment, for ensureing that mud and cement gel physical efficiency provide pressure and do not affect the normal operation of instrument, the side direction of described liquid cabin has open ports, the sealing of upper and lower two ends.According to existing engineering situation, the spacing between liquid cabin is 0.8 to 1.2 meter, within the scope of this, can meet the distance needed for actual measurement, can provide larger pressure reduction again.It should be noted that, fathom and the density of mud and colloid according to required, the spacing in rearrange liquids storehouse, make it to have comparatively significantly pressure change in different solutions.
In a further embodiment, in order to realize the accurate measurement of pressure differential, the two ends of described capillary tube are provided with sheet rubber and extend in two liquid cabin, and described sheet rubber is by a rubber ring and inner walls compact siro spinning technology.Meanwhile, in order to improve measuring accuracy, injection liquid force feed in capillary tube.Pressure is passed to capillary tube by the sheet rubber of sealing by the solution entering liquid cabin, and then produces pressure differential and transmitted by differential pressure pickup induction.
In a still further embodiment, in order to timely process information, improve testing efficiency, tester also comprises and is connected to signal amplifying apparatus between differential pressure pickup and data processing equipment and A/D converter.Its analog signal transmitted by differential pressure pickup is amplified, and is converted to data signal, processes and obtains the pressure differential of liquid in upper and lower liquid cabin.
In a still further embodiment, also comprise and be installed on housing and the warning lamp be connected with data processing equipment signal and jingle bell.
For preventing the situation of delivery deficiency, affect the normal work of instrument, described electric supply installation enters oneself for the examination battery and AC power.When extraneous nothing power supply or extraneous power supply are interrupted suddenly, battery can be instrument and provides power supply, ensures that instrument normally works.
Described differential pressure pickup is connected with data processing equipment by data wire, is provided with the plastic pipe of airtight connection in liquid cabin, and described data wire passes from plastic pipe.
During use, mud and cement colloid is utilized to enter the mineralization pressure of upper and lower liquid cabin, by sheet rubber this pressure passed to the hydraulic oil in capillary tube, thus make differential pressure pickup sensed pressure difference and transmission of analogue signal, the analog signal that differential pressure pickup transmits by main frame is amplified, be converted to data signal, process and obtain the pressure differential numerical value of liquid in upper and lower liquid cabin, and showing in suggestion device.
When this equipment arrives the interface of mud and cement colloid, this pressure differential numerical value can produce sudden change, exceedes set threshold value, and suggestion device will send alerting signal.The present invention is easy and simple to handle, and test speed is fast, and reliability is high, Accurate Measurement depth of mud also can remind constructor in time, ensure construction quality, save financial cost.
More than describe the preferred embodiment of the present invention in detail; but the present invention is not limited to the detail in above-mentioned embodiment, within the scope of technical conceive of the present invention; can carry out multiple equivalents to technical scheme of the present invention, these equivalents all belong to protection scope of the present invention.It should be noted that in addition, each the concrete technical characteristic described in above-mentioned detailed description of the invention, in reconcilable situation, can be combined by any suitable mode.In order to avoid unnecessary repetition, the present invention illustrates no longer separately to various possible combination.In addition, also can be combined between various different embodiment of the present invention, as long as it is without prejudice to thought of the present invention, it should be considered as content disclosed in this invention equally.
