The master who understands mechanical circuits please come in and do the little brother a favor

What are you**? The specific design needs to be communicated face-to-face, and the technical needs and understanding may not be consistent.

You still have some conditions here, or there are other things that I don't understand clearly, and you said that I can help you do it.

First, the cylinder goes down to press the workpiece? How tight? With what instructions? Distance or pressure?!

Second, then the motor is spinning? Which motor is this!? Is it the one with a pressure reducing valve or the one with a cylinder? Or is it an independent air source?

3. When the turntable is turned to 90 degrees. Now that there is a proximity switch, the original position may also have to add a point.

Fourth, the cylinder solenoid valve intake? It is contrary to the direction of the pressure to take in!? The other intake valve ???The cylinder solenoid valve starts the cylinder downward).

1. Press the start button K to start, the intermediate relay Z is energized, and its normally closed contact J starts 2 to disconnect the power supply of the cylinder upward solenoid valve, and the normally open contact J starts 1 to close, after releasing K start, due to the J start 1 engagement, Z start keeps the suction state, the cylinder descends to the solenoid valve F to get electricity, and the cylinder goes down to press the workpiece.

2. After the cylinder is in place, the position switch K is touched to make the positive rotation contactor C is energized, the main contact J is connected to the motor is turned on, and the secondary contact J is 1 turned on to keep C on and on.

3. After the motor rotates in place, it touches the reverse switch K reversal, and the reverse contactor C is reversed to obtain electric engagement, and in the process of suctioning, the first secondary contact J anti 2 (normally closed contact) is disconnected, and the positive rotation contactor C is lost and released, the main contact J is disconnecting the motor circuit, and the secondary contact J is 1 disconnecting the C positive control circuit. After C reverse engagement, the main contact J is reversed to the motor circuit, because the power supply phase sequence is A and C two opposite adjustments, the motor rotates in the opposite direction, and the secondary contact J reverse 1 suction keeps the circuit on.

4. When the motor reverses back to the initial position, the touch stops K stops, disconnects the Z start loop, J starts 1 and disconnects, the downward solenoid valve F is down, the reverse contactor C is not working, the motor stops rotating, J starts 2 normally closed contacts are turned on, the cylinder goes up to the solenoid valve F to get electricity to work, the cylinder goes up, and finally touches K stop to reset (restore closing), and a working cycle ends.

The working principle of the ice machine: after the installation of water and electricity, turn on the power supply--- start the compressor--- at the same time enter the Jiantong reclaimed water--- ice tray starts to defrost (become hot) - compressor starts (pre-cooling) refrigeration--- fan starts--- pumping motor starts pumping water to start making ice, when the ice is made to a certain thickness (there is a device to control the thickness of the ice) - the defrost valve opens the ice tray to become hot--- de-icing (the ice is melted down), there is a start to make ice, repeat the last action, when the ice is full of storage refrigerator, The falling ice will be located in the ice tray of the ice machine at the lower part of the water baffle, press down or open, a few minutes or the ice machine will stop, when the ice is cleared, its return to its position, the ice machine can start to make the mountain ice. All this is controlled by the circuit board program, and the weak current controls the strong current!

The principle is similar to that of air conditioning, but the use is different, the working principle is also very simple, start advanced water, refrigeration, water circulates on the evaporator, slowly freezes, when the ice cube is thick enough, there is temperature control or electronic probe to sense, the defrost valve intercepts the flow, the evaporator begins to heat, the ice cubes fall off, the imitation jujube shed ice plate switch is touched, the defrost valve stops working, starts refrigeration, water intake, and repeats. Provisions.

It's very general, typing is slow, I hope you can understand, if you have refrigeration technology, you should be able to clear the rock dust!

The AC output voltage of the magneto should reach more than 50V at 5000 rpm, if your AC output is only 29V, it is obvious that there is a problem with the lighting charging coil or that you are testing the method incorrectly. Your rectifier should be half-wave rectified, its charging DC voltage output should be around the right, the five wires of the magneto in addition to yellow, white, green, the other two should be black, red and blue, these two are for ignition, nothing to do with charging, ignore it. The yellow wire of the magneto stator is connected to the yellow wire end of the rectifier, the white wire is connected to the white wire end, the green wire is connected to the iron (the rectifier is also the green wire is connected to the iron), and the red wire end of the rectifier is connected to the battery for battery charging.

Now your charging voltage is low, in addition to the failure of the magneto stator coil, it may also be that the rectifier you replaced does not match the original car, or the wiring method is wrong.

When changing to a high-capacity battery, consider whether it is a match.

The connection method of the rectifier line: yellow to yellow, white to white, green wire to coil output green wire or tie iron, red wire to battery positive wire. There are 3 possible aspects of the fault you are talking about:

1.It is not good for the coil to generate electricity, and it is not good to change the coil or the magnetic coil to tie the iron. 2.

The rectifier is not good to tie the iron or replace. 3.There is an iron tie at the positive pole of the whole line.

The red wire is connected to the positive pole of the battery, and the green wire is connected to the iron.

The low-power three-phase motor can be changed to a single-phase motor, the original Y-shaped connection method of the motor is changed to the connection method, and when the capacitance can operate normally, the power will be reduced to the original 2 3 nearby, and the size of the distribution capacity is related to the power of the motor.

The normally open contacts of the photoelectric switch are connected to the coils of the time relay and connect them to the 220V; The normally closed contacts of the time relay are connected to the electromagnet and then they are also connected to the 220V. That's it.

It is recommended to use this circuit, connect the photoelectric switch at the start button, connect the electromagnet to the normally open contact and the neutral end at the second k, and adjust the potentiometer for a delay of 5s.

It cannot be directly connected to 220V, and a low-voltage 12V should be used to supply power to the light control circuit, timing circuit and the low-voltage end of the relay, and then control 220V to supply power to the electromagnet through the relay. There are a lot of related circuits, so go online and find them.

Don't be afraid to give it a try. The idea works!

Hehe, hello, I work as an electrician master in a textile factory, hehe, we do the warp knitting industry, and we will communicate together after what problems there are

I haven't studied it either, and it's the first time I've heard of programmables. We are now learning PLC, Programmable Logic Controller. I looked up the information and went back to talk.

Depending on the controller model, check online or at a bookstore.

In fact, you have to know that ** is simple.

You'll need a stepper motor, 2 travel switches, a circuit breaker, 2 contactors, 2 buttons, a thermal relay, and a time controller 1 @

General motors can be realized. There are upper and lower limit switches on the door. What does your time controller look like? Relays are needed. Contactors, and time relays are also required.

If you use a stepper motor in this case, it is cheaper to see whether you are giving current or signal, it is easy to give current Direct motor is less than DC100V to give signal is troublesome to use a driver Ordinary motors cannot control forward and reverse rotation.

123 Ground Input Output.

It should be possible.

The current is the wire speed, the voltage is the arc length, subject to the wire feeder, the current above is the arc current voltage, I give two recommended books, this book is currently I think that China's dioxide protection welding is the most classic one of the North China Electromechanical Publishing House, the other is the book called the principle of carbon dioxide protection welding and its debugging (this book has been read, now it is not good to buy) I don't know why it has not been published in the time.
