Abstract
The utility model relates to a control system for a proportional amplifier, which comprises intermediate relays (KA1), the proportional amplifier (EDC1), an ampere meter (A1) and proportional electromagnetic valves (YV1), wherein the interfaces (1), (2), (3) and (4) of the proportional amplifier are respectively connected with the four intermediate relays (KA1-1A1), (KA1-1A2), (KA1-1A3) and (KA1-1B); and the interfaces (11), (12), (13) and (14) of the proportional amplifier are respectively connected with the proportional electromagnetic valves (YV1-1A) and (YV1-1B) in parallel. The control system has the main characteristics that the requirement of high running speed of equipment can be met; a multispeed channel is capable of meeting the requirement of stable running; the control method is simple; and the regulation is easy.
Description
Technical field
The utility model belongs to electric control field, especially a kind of proportional amplifier control system.
Background technique
At present, cast cooling production line motion speed is very fast, but existing control system passage is few, control not steadily, also is difficult to simultaneously adjust, and can't satisfy the requirement that the production line Express Order Wire is cooled off in cast.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art part, provides a kind of and can satisfy requirement and the control mode proportional amplifier control system simple, that easily adjust that operates steadily.
The utility model realizes that the technological scheme of purpose is as follows:
A kind of proportional amplifier control system, comprise auxiliary reclay (KA1), proportional amplifier (EDC1), ammeter (A1), proportional electromagnetic valve (YV1), it is characterized in that: interface (1), (2), (3), (4) at proportional amplifier are connected with four auxiliary reclays (KA1-1A1), (KA1-1A2), (KA1-1A3), (KA1-1B) respectively, are parallel with proportional electromagnetic valve (YV1-1A) in interface (11), (12) and (13), (14) of proportional amplifier respectively and reach (YV1-1B).
And, described proportional electromagnetic valve (YV1-1A) series current table (A1).
Advantage of the present utility model and good effect are:
1, this control system main feature is for satisfying the fireballing requirement of cast cooling production line Express Order Wire equipment operation, and how fast passage can satisfy the requirement that operates steadily, and control mode is simple, easy to be adjusted.
2, this control system adopts proportional amplifier control ratio valve, thereby the operation of control oil cylinder guarantees that the operation of equipment quick and stable is particularly useful for cast cooling production line Express Order Wire.
Description of drawings
Fig. 1 is servo system structure figure of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and by specific embodiment, and following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.
Present embodiment is that example describes with cast cooling production line.
A kind of proportional amplifier control system, comprise auxiliary reclay KA1, proportional amplifier EDC1, ammeter A1, proportional electromagnetic valve YV, interface 1,2,3,4 at proportional amplifier is connected with four auxiliary reclay KA1-1A1, KA1-1A2, KA1-1A3, KA1-1B respectively, interface 11,12 and 13,14 at proportional amplifier is parallel with proportional electromagnetic valve YV1-1A and YV1-1B respectively, and wherein proportional electromagnetic valve YV1-1A series current Table A 1.
The operating software of native system is a GX Developer trapezoidal pattern programming software.
Working principle of the present utility model is:
When conducting is by the PLC program control for proportional electromagnetic valve, on behalf of the proportional valve control oil cylinder, YV1-1A stretch out, YV1-1B represents the withdrawal of proportional valve control oil cylinder, ammeter is used for the standby current amount, the size of current adjustment is by adjusting on the proportional amplifier, and the magnitude of current greatly then speed of oil cylinder operation is fast, and the speed of the little then oil cylinder operation of magnitude of current is slow, the running of whole cylinder, by the different conductings of KA relay constantly and the switch adjustment amount on the proportional amplifier control.
