The servo control device comprises a servo controller and a servo motor which are electrically connected. The servo controller is arranged in a control cabinet. The servo motor is connected to the air inlet valve or the air exhaust valve. The control cabinet is separated from the air inlet valve or the air exhaust valve. The servo control device has the advantages that influence on control part caused by high temperature can be eliminated, post-maintenance cost of the servo control device can be reduced, and reliability of the device is improved greatly.
Description
Technical field
The utility model relates to a kind of Servocontrol device, particularly a kind of for the suction valve of screw air compressor and the Servocontrol device of atmospheric valve.
Background technique
Air compressor produces form as a kind of important energy, is widely used in the links that life is produced.Especially the air compressor of the screw type numerous industrial trades such as machinery, metallurgy, electron electric power, medicine, packing, chemical industry, food, mining, weaving, traffic that are widely used, become compressed-air actuated product mainstream applications field.
In the prior art, it is one that the suction valve of screw air compressor and the control of atmospheric valve adopt electric and mechanical part, when work, the temperature of outlet pipe usually reaches 130 ℃ even higher, because temperature is very high, often there is problem in the control section of suction valve and atmospheric valve, the switching of suction valve and atmospheric valve is broken down, and causes whole air compressor to break down.
Model utility content
The technical problems to be solved in the utility model is in order to overcome the suction valve of screw air compressor and the control gear of atmospheric valve in prior art, problem often to occur, cause the switching of suction valve and the atmospheric valve defect such as break down, and a kind of Servocontrol device is provided.
The utility model is to solve above-mentioned technical problem by following technical proposals:
A kind of Servocontrol device, for controlling suction valve and the atmospheric valve of screw air compressor, its feature is, described Servocontrol device comprises a servocontroller, an actuating motor, described servocontroller and the electrical connection of described actuating motor, described servocontroller is arranged in a control cabinet, and described actuating motor connects suction valve or atmospheric valve, and described control cabinet and described suction valve or described atmospheric valve are separated from each other.Because control cabinet and suction valve or atmospheric valve are separated settings, be independent of each other between the two, so the high temperature at outlet pipe place is can not produce any impact to servocontroller in control cabinet, and, the actuating motor being connected with suction valve or atmospheric valve is again can be resistant to elevated temperatures, so also can not be subject to the impact of outlet pipe place high temperature.Like this, whole Servocontrol device is just not easy generation problem, and the switching of suction valve and atmospheric valve is also not easy to break down.
Preferably, described actuating motor comprises a speed reducer, and described speed reducer connects described suction valve or described atmospheric valve.Speed reducer can reduce the rotating speed of actuating motor, makes it be adapted to regulate the switching of suction valve and atmospheric valve.
Preferably, the output gear of described speed reducer is provided with a keyway, and described suction valve or described atmospheric valve are provided with a rotating shaft, and described rotating shaft is provided with a key, and described key is embedded in described keyway.By making key and coordinating of keyway the rotation of the output gear drive suction valve of speed reducer and the rotating shaft of atmospheric valve, to control the aperture of suction valve and atmospheric valve.
Preferably, described servocontroller is connected with a upper-position unit by Field bus.
Preferably, described actuating motor is ac synchronous motor.
Positive progressive effect of the present utility model is: Servocontrol device of the present utility model can be eliminated the impact of high temperature on control section, reduces Servocontrol device later maintenance cost, has greatly increased the reliability of device.
Accompanying drawing explanation
Fig. 1 is the structural representation of the Servocontrol device of the utility model preferred embodiment.
Fig. 2 is the structural representation of the actuating motor of the utility model preferred embodiment.
Fig. 3 is the right elevation of Fig. 2.
Embodiment
Lift a preferred embodiment below, and carry out by reference to the accompanying drawings the clearer the utility model that intactly illustrates.
The suction valve that Servocontrol device of the present utility model had both been applicable to screw air compressor is also applicable to atmospheric valve, below take suction valve and describes as example.
As Figure 1-3, Servocontrol device comprises a servocontroller 1, an actuating motor 2, and servocontroller 1 is connected by three electric wirings with actuating motor 2 on the one hand, is connected on the other hand by Field bus with upper-position unit 3.Servocontroller 1 is arranged in a control cabinet, the suction valve 4 of actuating motor 2 connecting screw rod air compressors, and control cabinet and suction valve 4 are separate.Because servocontroller 1 is arranged in control cabinet, separate completely with suction valve 4, and the actuating motor 2 being connected with suction valve 4 can bear high temperature, so the high temperature of outlet pipe has just been eliminated the impact of servocontrol part, so just guarantee the stable of whole system, greatly reduced rate of fault.
In order to slow down, in actuating motor 2, be provided with a speed reducer 5, in speed reducer 5, there is multi-stage gear interlock, the afterbody output gear of speed reducer 5 is provided with a keyway 6, simultaneously, the rotating shaft of suction valve 4 is provided with a key, cooperation by key and keyway 6 has realized being connected of suction valve 4 and speed reducer 5, has also realized being connected of suction valve 4 and actuating motor 2.
In real work, when system starts, actuating motor 2 sends seeks zero order, and actuating motor 2 drives into the rotating shaft of air valve 4 to specific direction rotation.When suction valve 4 forwards complete closed position or fully open position to, actuating motor 2 operations are obstructed, the electric current of actuating motor 2 sharply increases, servocontroller 1 reads the position of encoder in real time, the position of current encoder can be made as to zero-bit, servocontroller 1 just can be known the mechanical location of suction valve 4 like this.Positioning instruction is sent in the order that servocontroller 1 receives upper-position unit 3, drives actuating motor 2, and suction valve 4 is controlled, and the aperture of suction valve 4 just can accurately be controlled by servocontroller 1 like this.
The utility model is owing to adopting technique scheme, can eliminate the impact of high temperature on control section, the speed reducer 5 using is totally enclosed maintenance-frees, the actuating motor 2 using is ac synchronous motors, also be non-maintaining, essentially no maintenance cost of Servocontrol device later stage, has increased the reliability of installing greatly like this.
Although more than described embodiment of the present utility model, it will be understood by those of skill in the art that this only illustrates, protection domain of the present utility model is limited by appended claims.Those skilled in the art is not deviating under the prerequisite of principle of the present utility model and essence, can make various changes or modifications to these mode of executions, but these changes and modification all fall into protection domain of the present utility model.
