Abstract

The utility model relates to calibration equipment for a mass flow meter, which has simple structure and reliable function, and can improve the calibration precision of the flow meter and reduce the labor intensity of workers. The structure is as follows: the calibration equipment comprises a container cylinder which is sequentially connected with a pump motor, a standard flow meter and a flow meter to be calibrated by a pipeline; and the pump motor, the standard flow meter and the flow meter to be calibrated are all connected with a PLC (Programmable Logic Controller).

Description

The mass rate meter checking device
Technical field
The utility model relates to a kind of mass rate meter checking device.
Background technology
The flavoring and casing process control is two special processes in the fiber tow production process at present, the accuracy of detection of mass flowmeter directly influences the sucking quality at goods, because the measuring accuracy of mass flowmeter is very high generally at 1-1.5 ‰, for a long time, the verification of flowmeter adopts the method for artificial counting and electronic scale weighing comparison to carry out precision measure, and the existence of this problem has brought following two problems:
1, artificial counting exists than mistake, promptly begins counting and stop counting having the collimation error.
2, be subjected to the influence of the restriction of measured container and measuring vessel capacity, generally about 20KG, also there is big gross error in the measurement cumulative amount to accuracy computation.
3, measuring once the result need remove the peel container, with twice weighing of sample weighing, also has cumulative errors, and also there is bigger systematic error in accuracy of detection.
Summary of the invention
The purpose of this utility model is exactly in order to address the above problem, and a kind of mass rate meter checking device of simple in structure, reliable in function is provided, and it can improve the checking precision of flowmeter, reduces working strength of workers.
For achieving the above object, the utility model adopts following technical scheme:
A kind of mass rate meter checking device, it comprises the container cylinder, the container cylinder is connected with pump motor, proving flowmeter and flowmeter to be calibrated successively by pipeline; Pump motor, proving flowmeter and flowmeter to be calibrated all are connected with the PLC control device.
Described container cylinder is connected with pump motor by outlet valve, and flowmeter to be calibrated is connected with the container cylinder by back-water valve (BWV).
Described pump motor also is connected with clear blowpipe road, and clear blowpipe road is provided with blows valve clearly.
The utility model makes full use of the intelligentized characteristics of PLC, and the principle that it equates with the fluid to be measured quality of outflow based on any 2 inflows in one section sealing and circulating pipe designs, and its course of work is:
In the container cylinder, inject certain water, connect on-the-spot pipeline, open outlet valve and back-water valve (BWV), move by PLC control device control pump motor, two flowmeters are worked simultaneously, treat that whole pipeline is full of water, the verification personnel press the verification start button of PLC control device, the PLC control device is by a metering of output initiation command, at this moment two flowmeters measure simultaneously, after a period of time, the verification personnel press the verification stop button in the PLC control device, and the PLC control device sends metering and ceases and desist order, and finish the collection of the cumulative amount of two flowmeters, simultaneously the PLC control device calculates this section period and flows through the cumulative amount of the water in the pipeline, draws the measuring accuracy of flowmeter to be calibrated at last.
In checking procedure,, also has flowmeter dynamic check function by PLC control device control pump rotating speed of motor.
Verification finishes, and that presses the PLC control device blows button clearly, and close outlet valve this moment, opens and blow valve clearly, the fluid to be measured in the pipeline can be blown in the backwater cylinder, keeps cleaning noresidue liquid in the pipeline.
The beneficial effects of the utility model are:
1, this programme has solved original flowmeter verification and uses static the title to compare, and can produce the big problem of verify error
2, realized the full-automatic process of checking procedure, proving flowmeter error precision accuracy is improved greatly
3, realize dynamic check, alleviated the workload of checking flow meter.
