Solenoid valve is one of the important components of many large-scale instruments, and it is also an indispensable part of many tool products. Without it, we may not be able to obtain satisfactory practical effect. So how can we maximize the value of the solenoid valve, so that we can harvest the best effect? The answer includes not only the purchase choice in the early stage, but also the installation and wiring, use and maintenance in the later stage. Therefore, this part of the information is emphasized in the compilation.
1、 How to connect the solenoid valve? It has three wires, black, white, red. The black wire is the negative pole, and the white and red are the positive pole of 24 v. if the point is not connected correctly, the resistance between black and white is about 115 kilo ohm, and the resistance between black and red is about 50 Ω. If it is not near these values, but is very large, megaohm level, it indicates that the solenoid valve is broken.
2、 How to connect ax diesel engine electric flameout controller? Wiring methods: 1. Connect the red wire to the positive pole of the battery (normal power supply); 2. Connect the green wire to the on position of the fire lock switch; 3. Connect the black wire to the negative pole of the battery (grounding); 4. Connect the yellow wire to the start or Y gear of the ignition switch.
3、 What are the green, yellow and blue wires of the solenoid valve respectively? They are the signal lines for measuring the rotation speed of the motor. The white and black wires are used to connect the starting capacitor, and the red wires are used as com. There should be CW and CWW on the connection diagram measured by the speed controller. The rotation direction of the motor can be changed by changing the wiring of these two terminals.
4、 Working principle of solenoid valve
There is a coil in the solenoid valve which is the same as that of the generator. When the solenoid valve is energized, the magnetic force is generated to pull the power-off switch back to the oil supply. When the power is cut off, there is no magnetic force. If the flameout is pushed to the flameout position by the spring, there will be no oil supply. After the RO solenoid valve is used for a long time, the piston is easily blocked by dust and dirt and cannot move, and then it can not start or stop. It needs to be removed and cleaned. Lubricating oil cannot be applied inside because the solenoid valve is close to the engine. The lubricating oil is easy to mix with dust and is evaporated into mud by the high temperature of the engine. When such a problem occurs, it can be manually pulled, fixed, or removed and changed into a wire pull, of course, it can also be cleaned or replaced
In order to achieve the best practical use effect of solenoid valve, and to help obtain satisfactory advantage experience, the above example introduces the wiring skills of solenoid valve, including the operation steps of professionals and various details and precautions, and we find that it is not enough to only focus on how to connect, because the basic part of the original Introduction is equally important, so you should also learn the second half of the above information in-depth understanding.
