Abstract

A diaphragm pump on-line detection system belongs to the technical field of detection system technology, and especially relates to a diaphragm pump on-line detection system which conducts on-line detection and trend judgment on a diaphragm pump. The diaphragm pump on-line detection system comprises a diaphragm pump state parameter acquisition unit, transmitters, a PLC, an industrial personal computer, and structural features of the system are that diaphragm pump state parameter acquisition unit ports, transmitter ports and PLC ports are connected in sequence, and the PLC communicates with the industrial personal computer.

Description

A kind of diaphragm pump on-line detecting system
Technical field
the utility model belongs to the detection system technical field, relates in particular to a kind of diaphragm pump on-line detecting system.
Background technique
reciprocating piston diaphragm pump is that a kind of motor drives slidercrank mechanism through speed reducer; Drive reciprocating motion of the pistons; Piston makes the concavo-convex motion of diaphragm of rubber by oily medium, orders about the variation of barrier film chamber internal volume cycle, accomplishes the device that ore pulp is carried.
The operating conditions of diaphragm pump is abominable, and maximization, complicated day by day, and the probability that produces trouble or failure is increasing; And cause stopping production in case break down, can bring a large amount of unnecessary economic losses to enterprise.Meanwhile,, make a lot of information intercouple, and many fault messages have the non-linear and non-stationary of height, difficult identification and diagnosis because the complexity of diaphragm pump is interrelated between each constituent element.Therefore, a kind of can to carry out system that online detection and trend judges to diaphragm pump be necessity very in design.
Summary of the invention
the utility model is exactly to the problems referred to above, and a kind of diaphragm pump on-line detecting system that can carry out online detection and trend judgement to diaphragm pump is provided.
are for realizing above-mentioned purpose; The utility model adopts following technological scheme; The utility model comprises diaphragm pump status parameter collecting unit, transmitter, PLC, process control machine; Its structure outline diaphragm pump status parameter collecting unit port, transmitter port, PLC port link to each other successively, and PLC communicates by letter with process control machine.
as a kind of preferred version, said PLC of the utility model and process control machine are radio communication.
as another kind of preferred version, the said diaphragm pump status parameter of the utility model collecting unit involving vibrations sensor, temperature transducer, pressure transducer, flow transducer, concentration sensor.
in addition, the said temperature transducer of the utility model adopts infrared temperature sensor.
the utility model beneficial effect: the utility model diaphragm pump status parameter collecting unit port, transmitter port, PLC port link to each other successively, and PLC communicates by letter with process control machine; Can carry out online detection and trend judgement to diaphragm pump, thereby reduce the parking accident of catastrophic failure, help reducing the rate of fault of diaphragm pump, improve the transfer efficiency of pipeline.
Description of drawings
further specify the utility model below in conjunction with accompanying drawing and embodiment.The utility model protection domain not only is confined to the statement of following content.
Fig. 1 is the utility model schematic block circuit diagram.
Fig. 2 is the utility model program flow diagram.
Embodiment
are as shown in the figure, and the utility model comprises diaphragm pump status parameter collecting unit, transmitter, PLC, process control machine, and diaphragm pump status parameter collecting unit port, transmitter port, PLC port link to each other successively, and PLC communicates by letter with process control machine.
The output of said diaphragm pump status parameter collecting unit is as the input of transmitter; The output of transmitter is as the input of the D/A modular converter of PLC; The output of D/A modular converter is as the input of the CPU of PLC; The output of the CPU of PLC is as the input of signal transmitting terminal, and the output of signal transmitting terminal is as the input of signal receiving end, and the output of signal receiving end is as the input of process control machine.Process control machine is put in order, is analyzed and sum up signal data, forms diaphragm pump operation form and trend knowledge base, estimates with abnormal conditions in order to fault and reports to the police.
said PLC and process control machine are radio communication; Need not wiring, use, easy to maintenance.
said diaphragm pump status parameter collecting unit involving vibrations sensor, temperature transducer, pressure transducer, flow transducer, concentration sensor.Through collection and analysis to diaphragm pump vibration, temperature, pressure, concentration, flow parameter, can in time make judgement, thereby the fault critical state is estimated the runnability and the trend of pump, the abnormal work state is reported to the police.
said temperature transducer adopts infrared temperature sensor; Need not diaphragm pump is carried out structure of modification, easy to use.
are below in conjunction with the testing process of description of drawings the utility model.
Parameter initialization at first, is carried out to system in , and the detection position of sensor is set, and carries out data capture; The data that collect are carried out pretreatment such as filtering, denoising through PLC, and in PLC, store and computing.
are transported to process control machine with data by PLC through wireless network and carry out data display, arrangement and analysis then.
are last, get into the alert program of process control machine.If signal surpasses alarm threshold value, and inartificial cancellation warning, system will send alarm signal; If signal surpasses alarm threshold value, perhaps surpass alarm threshold value and still cancelled warning, then system does not send alarm signal, proceeds data collection task.
it is understandable that; More than about the specific descriptions of the utility model; Only be used to the utility model is described and be not to be subject to the described technological scheme of the utility model embodiment; Those of ordinary skill in the art should be appreciated that still and can make amendment or be equal to replacement the utility model, to reach identical technique effect; As long as satisfy the use needs, all within the protection domain of the utility model.
