Description
Technical field
The present invention relates to a kind of gas supply system, and in particular to the protector according to air pressure real-time regulation in bottle supplies system
System.
Background technology
Protective gas refers to that it makes high temperature gold for protecting the gas of metal drop, molten bath and weld metal zone in welding process
Belong to the infringement from ambient atmos.Protective gas can be divided into two classes：Inert gas and active gases.Inert gas refers to helium
Gas and argon gas, never react, for MIG welding (metal-noble gas arc welding) with melting weld seam.Active gas
Body, generally comprises carbon dioxide, oxygen, nitrogen and hydrogen.These gases are by stablizing electric arc and ensuring that material is smoothly transmitted
Welding process is participated in weld seam, when major part is accounted for, weld seam can be destroyed, but can improve weld characteristicses on the contrary on a small quantity,
For MAG welding (metal-active gases arc welding).Protective gas is used to protect metal drop in welding process, to welding
Productivity ratio and quality usually play an important roll.Protective gas prevents the melting weld seam in solidification from aoxidizing, while also hindering
Moisture in gear impurity and air, corrosion resistance, product that it may weaken weld seam by changing the geometrical property of seam
Angry hole simultaneously weakens the durability of weld seam.Protective gas also can cool down welding gun.
Existing welding protection gas supply system is general, and accuracy is low by the way of control flow manually, meanwhile, by
It is stressed the influence with openings of sizes double factor in gas flow, and controls that openings of sizes can only be controlled manually, and was welded
Real-time regulation is difficult in journey, therefore, the use of protective gas often has gap with ideal situation.
The content of the invention
The technical problems to be solved by the invention are existing welding protection gas supply systems typically using control manually
The mode of flow, accuracy is low, the influence with openings of sizes double factor simultaneously as gas flow is stressed, and controls manually
System can only control openings of sizes, therefore, the use of protective gas often has gap with ideal situation, it is therefore intended that provide according to bottle
The protector supply system of interior air pressure real-time regulation, solves the problems, such as high precision in control shield gas flow rate.
The present invention is achieved through the following technical solutions：
According to the protector supply system of air pressure real-time regulation in bottle, including processor and connection signal on a processor
Input module and at least one gas cylinder module, the gas cylinder module include pressure sensor, electric control valve and field controller；
Signal input module：Outer signals are received, to processor transmitted traffic signal and the scaling signal of each gas cylinder；
Processor：Flow signal and the scaling signal of each gas cylinder that signal input module sends are received, is obtained after calculating
The control signal of each gas cylinder, sends control signals to corresponding gas cylinder module；
Pressure sensor：Pressure in detection gas cylinder, generates pressure parameter in real time；
Electric control valve：Control signal according to field controller is acted；
Field controller：The control signal that receiving processor sends, reads the pressure parameter that pressure sensor is detected, root
According to the ratio that pressure parameter control electric control valve is opened.In welding job, user is input into by signal input module and protected
These parameters are sent to processor by the flow percentage of the total flow of gas and each gas cylinder, signal input module, treatment
Device draws the flow of each gas cylinder by technology, and showing in gas cylinder module is sent to using the flow of each gas cylinder as control signal
Field controller, after field controller receives the control signal of processor transmission, first reads in gas cylinder from pressure sensor
Pressure, according to the unlatching ratio of electric control valve on the calculation of pressure gas cylinder in gas cylinder, control electric control valve is opened.
The pressure sensor, electric control valve and field controller constitute an independent closed-loop control system.With scene
The control system that controller is controller, pressure sensor is sensor, electric control valve is actuator uses closed-loop control, does not receive
The influence of external parameter, it is preferred air-flow is more stablized using PID control.
Display screen is also associated with the processor.Parameters in processor are shown in real time, so as to user
Check.
Alarm module is also associated with the processor.Alarmed when air pressure is too low in gas cylinder；Field controller control
Alarm signal to processor is sent when electric control valve processed opens ratio more than 90%, processor controls report after receiving alarm signal
Alert module action.
The present invention compared with prior art, has the following advantages and advantages：
1st, the protector supply system according to air pressure real-time regulation in bottle of the invention, according to the Stress control gas cylinder in gas cylinder
The opening angle of valve, accuracy is high；
2nd, the protector supply system according to air pressure real-time regulation in bottle of the invention, user only needs to once be set,
Need not be adjusted again in use.
