Description
Technical field
The utility model relates to a kind of scraper-type flowmeter, is used to measure the fluid media (medium) that contains impurity and high twist, belongs to the volumeter technical field.
Background technology
Characteristics such as the scraper-type flowmeter has the precision height, the life-span is long, flow range is wide, viscosity adaptability is strong, operating sound is low.Flow in the past is in respect of following several: the electromagnetic flowmeter flow range is big, and bore wide ranges, but the very low liquid of energy measurement conductivity not are as petroleum product; Differential pressure flowmeter sound construction, stable and reliable for performance, long service life, have wide range of applications, but measuring accuracy is generally on the low side, rangeability is narrow, generally only 3: 1～4: 1, on-the-spot mounting condition require high, crushing is big; Volumeter measuring accuracy height, pipe laying condition are wide to measurement, rangeability that measuring accuracy does not influence, can be used for high viscosity liquid, but complex structure is bulky; Ultrasonic flow meter can be done non-contact measurement, but time propagation method can only be used for clean liquid and gas; Suspended body flowmeter is simple in structure, easy to use, but compression resistance is low, and the frangible greater risk of glass tube is arranged; It is good that vane-wheel type flowmeter high precision, good reproducibility, inferred-zero are disturbed ability, but can not keep calibration characteristics, etc. for a long time.
The utility model content
The purpose of this utility model provides a kind of complex structure and the little volumeter of volume.
In order to reach several above-mentioned purposes, the technical solution of the utility model has provided a kind of scraper-type flowmeter, comprise shell, be respectively equipped with import and outlet in the both sides of shell, it is characterized in that, the gear wheel rotor is located in the shell by the first rotor chamber, the pinion wheel rotor is located at gear wheel rotor bottom both sides by second rotor chamber, be provided with the transmitter erecting frame on the top of shell, the tongue tube sensor is located in the transmitter erecting frame by the sensor mounting blocks, and the tongue tube sensor connects calculating and control device.
Gear wheel and pinion wheel rotor rotate under the effect of flowmeter import and export differential pressure, and a moving week of revolution is discharged the flow volume of " metric space ".As long as measure number of revolutions, just can calculate the volume of discharging fluid.Gear wheel and pinion wheel do not have metal to contact with the direct of metal between changeing.Do not have contact just not have wearing and tearing, do not have wearing clearance just can not increase, number of dropouts is not strengthened in the gap just not to be increased, and number of dropouts does not strengthen then accuracy and protects unanimity forever.Each rotor of gear wheel and pinion wheel all rotates around the axle center of oneself, in the overall process of rotating, the angle that the outer circumference surface of gear wheel and each rotor of pinion wheel forms remains unchanged, and every rotation half-turn, each rotor of gear wheel and pinion wheel forms the impurity " passage " (it is little to stimulate the menstrual flow, and " passage " size is then little) of 1～20mm naturally in the different time.Guaranteed thick substances and the smooth and easy measurement that contains media such as pricker dimension, sand grains.According to said structure as can be seen, the scraper-type flowmeter that the utility model provides simplifies the structure when having guaranteed measuring accuracy greatly.
This shows, the utility model has the advantages that: be simple in structure and volume is little when guaranteeing measuring accuracy.
