Description
Technical field
The utility model relates to test drilling fluid filtration device technique field, is a kind of portable middle pressure filter press.
Background technology
Drilling fluid filtration is an important indicator of drilling fluid, and each formula of shop experiment needs test, and the scene needs to monitor at any time.Indoor general employing high pressure nitrogen is as pressure source, and on-the-spot convenience in order to carry and to use adopts inflator to substitute high-pressure air source more.In test process, because of the gas flow of inflator storage limited, when experiment begins to ventilate, test pressure is down to again below test pressure after rising rapidly, and this is because due to bleed pressure decline, at this moment needs in time to replenish source of the gas air pressure to more than test, could continue test, and the fluctuation of pressure can have influence on test result, makes test result inaccurate.
Summary of the invention
The utility model provides a kind of portable middle pressure filter press, has overcome the deficiency of above-mentioned prior art, and it can effectively solve the easy fluctuation in present mensuration drilling fluid filtration course pressure source and cause the inaccurate problem of test result.
The technical solution of the utility model realizes by following measures: a kind of portable middle pressure filter press comprises gas-holder, cooling gas check valve, drilling fluid cup, reduction valve, the first tensimeter and the second tensimeter; Be installed with cooling gas check valve on the tank mouth of gas-holder, be installed with associated line between the bottom of cooling gas check valve and drilling fluid cup, be installed with reduction valve on associated line, be installed with gas source switch on associated line between reduction valve and drilling fluid cup, be installed with the first tensimeter on gas-holder, be installed with the second tensimeter on reduction valve.
The below is the further optimization and/or improvements to above-mentioned utility model technical scheme:
The lower end of above-mentioned reduction valve can be installed with support, is installed with base in the lower end of support.
The utility model reasonable and compact in structure, easy to use, by the improvement of compressed air source unit, provide single test required tolerance, guarantee that test pressure is steady, improve the accuracy of test result, and the utility model is easy to carry.

Embodiment
The utility model is not subjected to the restriction of following embodiment, can determine concrete embodiment according to the technical solution of the utility model and actual conditions.
In the utility model, for convenience of description, the description of the relative position relation of each parts is all that the Butut mode according to Figure of description 1 is described, as: the position relationship of forward and backward, upper and lower, left and right etc. is to determine according to the Butut direction of Figure of description.
Below in conjunction with embodiment and accompanying drawing, the utility model is further described:
As shown in Figure 1, this portable middle pressure filter press comprises gas-holder 1, cooling gas check valve 2, drilling fluid cup 3, reduction valve 5, the first tensimeter 7 and the second tensimeter 8; Be installed with cooling gas check valve 2 on the tank mouth of gas-holder 1, be installed with associated line 4 between the bottom of cooling gas check valve 2 and drilling fluid cup 3, be installed with reduction valve 5 on associated line 4, be installed with gas source switch 6 on associated line 4 between reduction valve 5 and drilling fluid cup 3, be installed with the first tensimeter 7 on gas-holder 1, be installed with the second tensimeter 8 on reduction valve 5.during use, the utility model is fixedly mounted on support, first drilling fluid is poured in drilling fluid cup 3, O-ring seal and filter paper on pad, cover the filter screen lid, fixing rear inversion is contained on support, then air intake opening and the associated line 4 with drilling fluid cup 3 bottoms is fixedly installed togather, then gas-holder 1 is inflated, measure at last drilling fluid filtration, adopt cooling gas check valve 2 on gas-holder 1, can prevent the drilling fluid suck-back, the first tensimeter 7 detects the interior gaseous tension of gas-holder 1, as find pressure decreased, can replenish by inflator, gas-holder 1 internal pressure is not less than test pressure and gets final product.
Can according to actual needs, above-mentioned portable middle pressure filter press be made further optimization and/or improvements:
As shown in Figure 1, be installed with support 9 in the lower end of reduction valve 5, be installed with base 10 in the lower end of support 9.Mounting bracket 9 and base 10 make the utility model in use solid and reliable.
Above technical characterictic has consisted of most preferred embodiment of the present utility model, and it has stronger adaptability and best implementation result, can increase and decrease according to actual needs non-essential technical characterictic, satisfies the demand of different situations.
the use procedure of the utility model most preferred embodiment: drilling fluid is poured in drilling fluid cup 3, O-ring seal and filter paper on pad, cover the filter screen lid, fixing rear inversion is arranged on support 9, inject air through cooling gas check valve 2 with inflator in gas-holder 1, make its pressure higher than 100Psi, regulate reduction valve 5 to second manometric pressure to 100Psi, open gas source switch 6, beginning timing measuring drilling fluid filtration, dehydration drips through filter screen from drilling fluid cup 3, being collected into minute with graduated cylinder finishes, close gas source switch 6, bleed off simultaneously air in drilling fluid cup 3 to normal pressure, test finishes, read the volume of liquid in graduated cylinder.
