Abstract
The utility model discloses a novel turbine flowmeter, comprising a housing, fasteners, a front guide pipe, a thrust plate, an impeller, a magnetic induction coil, a magnetoelectric induction type signal detector, a bearing and a back guide pipe. The front guide pipe and the back guide pipe are connected with the inner wall of the housing through the fasteners; one end of the bearing is fixedly arranged at the outlet end of the front guide pipe; the other end of the bearing is fixedly arranged at the inlet end of the back guide pipe; the thrust plate is arranged on the bearing; the impeller is arranged on the bearing; the outer surface of the housing provided with the impeller is provided with the magnetic induction coil; the magnetoelectric induction type signal detector is arranged above the magnetic induction coil; and the outlet end of the magnetoelectric induction type signal detector is connected with an external detection device. The novel turbine flowmeter has low requirements on purity of a liquid medium, requirements on the front and back straight pipe sections of an instrument during installation do not exist, instantaneous flow can be measured, and accumulate flow can also be measured; and the novel turbine flowmeter has the advantages of simple structure, less pressure loss, high sensitivity, low cost and good stability.
Description
Technical field
The utility model relates to a kind of flowmeter, refers more particularly to a kind of novel turbo flow meter.
Background technology
Flow instrument is the instrument that flows through the total amount (but also claiming integrated flux) of cross-section of pipeline in liquid (or gas) in the closed conduct flows through cross-section of pipeline in the unit interval amount (claim not only instantaneous delivery) and certain period for measuring.Flow instrument divides two big classes in principle both at home and abroad at present: a class is called the speed mode instrument, count the typical case with turbine flow, a rotor is often arranged in this instrument, when flowing through instrument, fluid promotes the rotor rotation, obtain the rotor gyro frequency by sensor, this frequency is directly proportional with the speed that fluid flows through cross-section of pipeline, obtains the instantaneous delivery that fluid flows in pipeline thus.This meter sensitivity height, the pressure loss is little, and is simple in structure, with low cost.But because the rotor of itself, therefore bearing arrangement has relatively high expectations to the degree of purity of medium, namely can not contain a bit impurity in the medium, otherwise rotor will be stuck.This instrument can only be applied to water, and milk and finished product wet goods medium can not be applied to a large amount of media that contain impurity (such as former wet goods) that use on the commercial production.Long-term use can make rotor, bearing wear in addition, and instrument coefficient changes, the instrument poor stability.The velocity distribution of this instrument convection cell on cross-section of pipeline is very responsive, therefore in order to guarantee measurement verification and the actual consistance of using, often require the instrument front and back that the straight length of certain-length is arranged, this brings very big trouble for installation, design in actual the use.Second class claims the positive displacement instrument, with rotz flowmeter, oval gear flowmeter is representative, in this instrument measurement chamber is arranged, after flow is filled measurement chamber, the chamber inner fluid is flowed to the downstream, rotate by cavity, so measure the flow total amount that the measurement chamber number of revolutions can obtain to flow to by instrument the downstream, therefore the positive displacement instrument measurement is integrated flux, and this metering instrument precision is higher, requires lower to the medium degree of purity, good stability, but complex structure, the pressure loss is big, and cost is quite high, sensitivity is lower, and instrument structure is huge.
The utility model content
The purpose of this utility model just is to provide in order to address the above problem a kind of novel turbo flow meter of simple in structure, sensitivity.
The utility model is achieved through the following technical solutions above-mentioned purpose:
The utility model comprises housing, securing member, preceding guide pipe, thrust plate, impeller, magnetic induction coil, the magnetoelectric induction signal detector, bearing and back guide pipe, guide pipe is connected with described inner walls by described securing member with described back guide pipe before described, one end of described bearing is fixed on the endpiece of described preceding guide pipe, the other end of described bearing is fixed on the entrance point of the preceding guide pipe in described back, described thrust plate is arranged on the described bearing, described bearing is provided with described impeller, install described impeller housing outer surface be provided with described magnetic induction coil, the top of described magnetic induction coil is provided with described magnetoelectric induction signal detector, and the output terminal of described magnetoelectric induction signal detector is connected with external pick-up unit.
The beneficial effects of the utility model are:
The utility model to the liquid medium degree of purity require low, do not have when installing requirement to straight length before and after the instrument, can measure instantaneous delivery and can measure integrated flux again, simple in structure, the pressure loss is little, highly sensitive, with low cost, good stability.
