I have imported several milling machines in the CNC center of our factory. When the work is automatically clamped, the tool change is released, and the air pressure cannot be separated. In order to ensure the normal operation of the machining center, the working pressure of the air compressor must be kept at 0.60. ultra. After 8 years. The two safety valves of the pressure tank automatically open and the deflation motor continues to operate. The machine can be stopped until the end of the processing class. This way the single motor runs continuously for a long time. Causes the motor to heat up severely. The thermal relay action often occurs, causing the piston of the compressor to rise too high and wear faster. To solve this contradiction. A new air compressor unit of the same type has been added to the factory. But for a long time, people need to alternately start and stop. Every time you open the air press, you must turn the faucet back on, use the gas, and turn off the water. Very complicated. There was also an accident in which the water broke the compressor. Machining centers are often troubled by air pressure. The tool is not in place and is sometimes stuck. To ensure that the machining center 2 is in transit. I have set up a circuit that can open and stop and manually open and stop any compressor, and has the protection function of starting the compressor before boiling water. The following describes the working process of closing the reverse 1 electromagnet. The water of the water bamboo flows into two free cooling. Cooling water enters the liquid level and is loaded. Then flow out. As long as the cooling water enters the liquid level device. Both electrodes will be turned on.

The base of 07 is powered. 02100 pull-in water indicator light is on. At the same time, the contact of 1 provides an automatic and peaceful opening air compressor to provide a way to manually dial 84 to energize the line.

The process is as follows, from the point normally closed normally closed to the Xinjiang 2 coil through the thermal relay and the ground to form a loop, at this time 2 pull, elbow 2 motor starts running. After 2 hours, it is set as needed. After several delays, the normally open contact is turned on to energize the magic coil. The normally closed operation cuts off the 2 coil circuit and stops the elbow 2 motor. The same, 2 lines get electricity. The stepping operation of D1 provides the normally open contact of condition CK2 through the KM2 normally closed point.

The coil is energized and the elbow 1 motor enters the work. After 2 hours, the delay of 2 is normally closed, causing the Minai coil to lose power, and the 101 time delay normally open contact is broken. At this time, the 2 coil motor is cut off again. The normally closed contact is again turned on and the 12 coil 412 starts a new job. This continues to circulate continuously. Observe the red and yellow light to understand the compressor without electricity. The circuit breaker in the middle is set for the purpose of ensuring personal safety during maintenance. If you need to overhaul that one, disconnect the corresponding circuit breaker.

This device can also be versatile to other locations. Multiple motors can be automatically cycled. Rotate work. Long time, you need to choose different types of time relays, this circuit is safe and reliable from external interference.

Better weld formation: YIHONG or STARTNOW welding head,Swing welding mode, spot width can be adjusted, welding fault tolerance is strong, make up for the disadvantage of laser welding spot small, expand the tolerance range of machining parts and weld width, get better weld forming.
