The utility model discloses volume flow that can automatically regulated diaphragm compressor is suitable for the user and because of using reasons such as operating mode or technology change to cause the change of flow parameter, has improved diaphragm compressor's the utilization and the rate of utilization, has saved the cost.
Description
Technical field
The utility model relates to a kind of automatic flow rate adjusting device, specifically a kind of diaphragm type compressor automatic flow rate adjusting device.
Background technique
Membrane compressor is a kind of positive displacement compressor of special construction, has the advantages that compression ratio is large, good airproof performance, pressurized gas are not polluted by lubricant oil and other solid impurity.Usually, diaphragm type compressor is primarily of compositions such as driving mechanism, cylinder part, lubricating oil system, air pipe parts, crankcase components.According to the working principle of membrane compressor, the size of its flow determines primarily of the size of the cylinder of diaphragm type compressor and suction pressure, and usually, the user of diaphragm type compressor, always selects diaphragm type compressor according to maximum air consumption.But in actual production, for various reasons, user requires the flow changing diaphragm type compressor, to be suitable for the need of production of reality, such as: (1) is due to flow process and technologic reason requirement minimizing air demand; (2) due to the change of other equipment, machinery and tools characteristic, also require that the air displacement of diaphragm type compressor adjusts frequently.
Learn from the action principle of compressor, diaphragm type compressor also belongs to the category of positive displacement compressor, the flow of positive displacement compressor can not reduce automatically due to the rising of back pressure, if effectively do not regulated, even peril is there will be in some occasion, if former compressor continues to use, must change and be suitable for the compressor that user changes flow parameter, like this can the user cost of adding users greatly.
Model utility content
The purpose of this utility model is to provide a kind of diaphragm type compressor automatic flow rate adjusting device, solve existing diaphragm type compressor and can not automatically regulate diaphragm type compressor flow according to user's usage requirement in time, cause the utilization of diaphragm type compressor and utilization rate is low, cost is high problem.
In order to achieve the above object, the utility model is achieved through the following technical solutions:
The utility model provides a kind of diaphragm type compressor automatic flow rate adjusting device, comprise flowmeter, pneumatic control valve and PLC control system, in the suction port pipeline and relief opening pipeline of diaphragm type compressor, tee union and tee union are installed respectively, the suction port of pneumatic control valve is connected with one end of tee union, the relief opening of pneumatic control valve is connected with one end of tee union, form the return line between diaphragm type compressor suction port and relief opening, flowmeter be arranged on tee union after the final exhaust ports of diaphragm type compressor, the air displacement of Real-Time Monitoring diaphragm type compressor, the flux signal monitored can be converted into electrical signal passes to PLC control system by control circuit simultaneously, PLC control system is connected with the control circuit of pneumatic control valve simultaneously.
Further improvement of the utility model is: flow counts explosion-proof type turbine flowmeter.
Further improvement of the utility model is: flowmeter is converted into 4 the flux signal monitored
~20mA electrical signal passes to PLC control system by control circuit.
Further improvement of the utility model is: tee union is reducing tee joint.
The beneficial effects of the utility model: the utility model can regulate the volume flow of diaphragm type compressor automatically, being suitable for user because of the reason such as applying working condition or process reform causes the change of flow parameter, substantially increase utilization and the utilization rate of diaphragm type compressor, provide cost savings.
The utility model is simple to operate, easy to use, automatically can regulate the flow of diaphragm type compressor in time according to user's usage requirement.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein: 1-tee union, 2-tee union, 3-flowmeter, 4-pneumatic control valve, 5-PLC control system, 6-diaphragm type compressor.
Embodiment
In order to deepen, to understanding of the present utility model, to be described in further detail the utility model below in conjunction with drawings and Examples, the present embodiment, only for explaining the utility model, not forming protection domain of the present utility model and limiting.
Embodiment as shown in Figure 1, the present embodiment provides a kind of diaphragm type compressor automatic flow rate adjusting device, comprise flowmeter 3, pneumatic control valve 4 and PLC control system 5, described flowmeter 3 is explosion-proof type turbine flowmeter, it is high that turbine flowmeter has precision, reproducible, inferred-zero drifts about, the advantages such as high range ratio, in the suction port pipeline and relief opening pipeline of diaphragm type compressor 6, tee union 1 and tee union 2 are installed respectively, described tee union 1 and tee union 2 are reducing tee joint, can reducing as required, the suction port of described pneumatic control valve 4 is connected with one end of tee union 2, the relief opening of described pneumatic control valve 4 is connected with one end of tee union 1, form the return line between diaphragm type compressor 6 suction port and relief opening, described flowmeter 3 is arranged on the final exhaust ports of the diaphragm type compressor 6 after described tee union 2, the air displacement of Real-Time Monitoring diaphragm type compressor 6, the flux signal monitored can be converted into 4 simultaneously
~20mA electrical signal passes to PLC control system 5 by control circuit, and PLC control system 5 is connected with the control circuit of pneumatic control valve 4 simultaneously.
After user inputs the flow value of change in the inputting interface of PLC control system 5, now control system this numerical value and the numeric ratio monitored by flowmeter comparatively, then the unlatching size of pneumatic control valve 4 is changed according to program, the gas that such part is discharged just can be back to the suction port of compressor by pneumatic control valve 4, thus ensures that the air displacement of diaphragm type compressor changes timely with the requirements of user.
The utility model is simple to operate, easy to use, automatically can regulate the volume flow of diaphragm type compressor, be suitable for user because of the reason such as applying working condition or process reform and cause the change of flow parameter, substantially increase utilization and the utilization rate of diaphragm type compressor, provide cost savings.
