Abstract
The utility model relates to a linear volumetric type effusion meter, which is characterized in that a pair of metering pistons are composed of an A metering piston 4 and a B metering piston 6, and an oil-in 1 and an oil-out 2 are connected with the two ends of the pair of metering pistons via a change-over valve 3, and a linear displacement sensor 5 is connected between the A metering piston 4 and the B metering piston 6. The utility model has the advantages that the effusion meter utilize the principle of reciprocating piston-type effusion meter and employ the method formed by measuring continuously pistons using linear displacement sensor, to measure volume flow ,thereby enabling the utility model to be applied for a fixing or moving device with strong intensity of vibration. A form of measurement of the linear displacement leads the measuring range of the linear volumetric type effusion meter of the utility model wider, and causes the resolution factor and accuracy higher without being affected by temperature and viscosity of the measured fluid, thereby the utility model is capable of adapting continuous measurement to the tiny flow rate of all kinds of non-corrodible liquid.
Description
One, technical field: the utility model belongs to a kind of liquid flowmeter measuring appratus or device, especially a kind of fuel injection pump tester dependent linearity volumeter.
Two, background technology: the critical component in the known technology in the diesel fuel injection system---injection pump all needs the debugging through fuel injection pump tester when making and keep in repair.Practical at present this kind equipment of the overwhelming majority is when the fuel delivery of test and adjustment, adopt measuring tank timing metered volume and artificial reading to carry out the discontinuity test, the disclosed successively fuel injection pump tester that utilizes the continuously automatic gauging of the supporting photoelectricity class of computing machine flow sensor, the flow sensor that uses on the phase equipment is mainly based on weighing sensing principle and grating chi sensing principle, thereby has the defective of complex structure and anti-vibration ability.
Three, summary of the invention: technical problem to be solved in the utility model is to propose the linear volumeter of a kind of small at the publicly-owned flow of each cylinder of injection pump, oily stream pulsating nature and the characteristics that flow velocity is low and measurement range is big.
The measure that overcomes the above problems is, the metering piston pair that A metering piston and B metering piston are formed, and oil-in is connected with metering piston pair two ends by reversal valve with oil-out, is connected Linear displacement transducer between A metering piston and B metering piston.
The mode that advantage of the present utility model is to adopt reciprocating piston type flowmeter principle and utilizes Linear displacement transducer continuous coverage piston to form is measured volume flow, it is possessed on the big fixing or mobile device of oscillation intensity uses, the metering method of linear displacement makes linear volumeter range ability of the present utility model bigger, resolution and precision are higher, be not subjected to the temperature and the viscosity influence of detected fluid, can adapt to the continuous coverage of the tiny flow quantity of various non-corrosive liquids.
