Abstract
A coated fabric impermeability measuring instrument is controlled by an 8031 single chip processor. A stepping motors and tooth-shaped belt transmission is adopted to drive a pressure source applying pressure to a cylinder-shaped metal bellow. The upper end of the cylinder-shaped metal bellow is connected with two static water pressure outlet hoses. One outlet hose is connected with an air-release valve and a pressure sensor, and the other outlet hose is connected with a water basin which can clamp the testing fabric. When the cylinder-shaped metal bellow filling up with water is applied pressure by the pressure source, the cylinder-shaped metal bellow is pressed and deforms, and the water is pressed into the static water pressure outlet hoses, applying static water pressure to the testing fabric through the water basin. The pressure value is sent to the 8031 microcomputer by the pressure sensor, being processed, and then sensed by an LED digital display. The utility model has the advantages of small volume, light weight, wide test range, high measuring precision, low cost, and the realization of the intelligent impermeability property detection for the coated fabric.
Description
Technical field
The utility model relates to a kind of testing tool that is used for yarn fabric, particularly relates to the impervious water tester of a kind of coated fabric.
Background technology
Along with developing rapidly of coated fabric, its inherent quality is more and more higher, and especially water resistance is become better and better, and the requirement that therefore resists the water test instrument is also more and more higher.At present, the test of yarn fabric water permeability resistance energy can be carried out by tester by a kind of yarn fabric water permeability resistance, hydrostatic force generating means in this instrument can apply hydrostatic force to tested fabric, adds that other servicing unit can detect the impervious outlet capacity of tested fabric.Hydrostatic force generating means in this quasi-instrument has three types at present: 1. promote water tank type, it is with the power that produces of flooding tested fabric directly to be applied hydrostatic force, because this quasi-instrument is by the generation pressure of flooding, so make this instrument that height more than 1 meter must be arranged; 2. water pump type, it is that the power that the water pump drainage produces directly applies hydrostatic force to tested fabric; 3. promote the mercury pot type, this method is identical with first type of principle, but mercury can not directly contact with tested fabric, to be that medium applies hydrostatic force to tested fabric with empty G﹠W, this method has been utilized the heavy characteristics of mercury, though reduced the height of instrument, increased the weight of instrument.In addition, the hydrostatic force that above-mentioned instrument produced is only limited in the 20Kpa, and for the new coating fabric, its hydraulic pressure can not be beaten fabric, can't produce the detection data.
Summary of the invention
In order to overcome the deficiencies in the prior art part, the utility model provides a kind of coated fabric impervious water tester, this instrument has volume, and little (350mm * 310mm * 300mm), test specification wide (0～10 meter water column) is a kind of by the very high intelligent tester of micro-processor controlled degree of accuracy.
The technical scheme that its technical matters that solves the utility model adopts is: by 8031 Single-chip Controlling, adopt stepping motor, the transmission of flute profile band, driving a pressure source exerts pressure to the cylindrical metal corrugated tube, the upper end of cylindrical metal corrugated tube is connected with two hydrostatic force delivery hoses, wherein one connects an air release and a pressure transducer, but another root connects the basin of a tested fabric of clamping, when the cylindrical metal corrugated tube of filling water is exerted pressure by pressure source, cylindrical metal corrugated tube compressive deformation, water is pressed into described hydrostatic force delivery hose, directly tested fabric is applied hydrostatic force by basin, its force value is delivered to 8031 microcomputers by pressure transducer and is handled, and is read by the LED digital indicator.
Usefulness of the present utility model is: this instrument volume is little, in light weight, and test specification is wide, the measuring accuracy height, and cost is low, can realize the intellectuality that can detect the coated fabric water permeability resistance.
Description of drawings
Accompanying drawing is the structural representation of the impervious water tester of coated fabric, and wherein: 1 is pressure source, and 2 is the cylindrical metal corrugated tube, and 3 is pressure transducer, 4 is air release, and 5 is the hydrostatic force delivery hose, and 6 is tested fabric, 7 is basin, and 8 is 8031 microcomputers, and 9 is the LED digital indicator; Described pressure source 1 is made up of motor 10 and gearing 11, and gearing 11 can be flute profile band, leading screw etc.
