Abstract
The utility model relates to a fluid metering supply device, which comprises a vacuum feeding barrel, a fluid raw material barrel, a compressed air inlet pipe, a fluid output pipe, a pneumatic regulating valve, a PLC controller and an electromagnetic switch, wherein the fluid raw material barrel is arranged inside the vacuum feeding barrel, the compressed air inlet pipe is arranged on the fluid raw material barrel via the vacuum feeding barrel, the fluid output pipe is arranged inside the fluid raw material barrel, the pneumatic regulating valve is arranged on the fluid output pipe, and the PLC controller is connected with the pneumatic regulating valve via the electromagnetic switch. Through adopting the structural style to control the fluid supply quantity of the system, the utility model ensures simpler and more convenient fluid raw material control, shortens the maintenance time of the device, and has the advantages of simple structure, convenient use and the like.
Description
Technical field
The utility model relates to a kind of quantitative feeding control system of supply of equipment fluid that is, a kind of specifically fluid metering feedway.
Background technology
A lot of equipment in use all have fluid to be supplied to equipment endlessly as raw MAT'L or consumptive material.And, adjust the supply of fluid according to the operational factor of equipment.Especially some exact instrumentss relatively, and even the size of fluid supply directly has influence on the quality of the product normal operation of equipment.
And the supply of existing fluid generally control by membrane pump, and membrane pump is the Pneumatic vacuum original paper.In use because long-time continuous is moved, and the fault rate height causes metering inaccurate, pressure is not enough, wastes time and energy and repair, and influences production time for membrane pump.Barrier film then is easy loss product, when diaphragm failures, then can cause fluid with in the vacuum suction vacuum pump, causes the damage of total system.Repair more consuming timely, seriously influence the output of producing, and the safe and stable operation of manufacturing line.Therefore inventing a kind of later-model fluid feed system is very important.
Summary of the invention
The purpose of this utility model be to provide a kind of can be accurately, stable control fluid, and shorten the fluid metering feedway of maintenance time.
The purpose of this utility model is to realize like this, this device comprises vacuum binder bucket, fluid material bucket, compressed air inlet pipe, fluid output tube, pneumatic adjusting valve, PLC controller, electromagnetic switch, described fluid material bucket is arranged in the vacuum binder bucket, compressed air inlet pipe through vacuum binder bucket be arranged on the fluid material bucket above, fluid output tube is arranged in the fluid material bucket, described pneumatic adjusting valve is arranged on the fluid output tube, and the PLC controller connects pneumatic adjusting valve through electromagnetic switch.
The utility model has shortened the maintenance time of equipment because the quantity that adopts the said structure form to come the control system accommodating fluid makes that the control of fluid material is more simple and convenient, has advantages such as simple in structure, easy to use.
Description of drawings
Fig. 1 is a kind of fluid metering feedway integral structure scheme drawing.
The specific embodiment
Shown in accompanying drawing: this device comprises vacuum binder bucket 1, fluid material bucket 2, compressed air inlet pipe 3, fluid output tube 4, pneumatic adjusting valve 5, PLC controller 6, electromagnetic switch 7, described fluid material bucket 2 is arranged in the vacuum binder bucket 1, compressed air inlet pipe 3 through vacuum binder buckets 1 be arranged on fluid material bucket 2 above, fluid output tube 4 is arranged in the fluid material bucket 2, described pneumatic adjusting valve 5 is arranged on the fluid output tube 4, and PLC controller 6 connects pneumatic adjusting valve 5 through electromagnetic switch 7.
System extrudes fluid by pressure, arrives pneumatic adjusting valve 5 by fluid output tube 4.Pneumatic adjusting valve 5 comes the passage period of the control flows scale of construction according to PLC controller 6 and electromagnetic switch 7, thereby the control flows scale of construction what come.
Make the pressure of vacuum barrel 1 and fluid material bucket 2 keep certain pressure poor by compressed air inlet pipe 3 input pressurized airs during use.When fluid use side 8 needed fluid, PLC controller 6 sent control signal, and electromagnetic switch 7 is opened pneumatic adjusting valve 5 and controlled passing through of fluid.Use vacuum barrel 1 to keep-up pressure, pressure is even, stable in the time of can making fluid output, accurate measurement, and the free of losses original paper, fault rate is low, convenient control.Guaranteed the accurate use of fluid.
