How to wire the air pump? Air pump wiring principle

Wiring diagram: <>

The working principle of the air pump is:

The engine drives the crankshaft of the air pump through two V-belts, which in turn drives the piston to pump the air, and the injected gas is directed through the air duct into the air reservoir. On the other hand, the gas cylinder is introduced into the pressure regulator fixed on the air pump through an air guide pipe, so as to control the air pressure in the air tank.

When the air pressure in the gas reservoir does not reach the pressure set by the pressure regulator, the gas entering the pressure regulator valve from the gas reservoir cannot open the pressure regulator valve; When the air pressure in the air reservoir reaches the pressure set by the pressure regulating valve, the gas entering the pressure regulating valve from the air reservoir opens the pressure regulator valve, enters the air passage that communicates with the pressure regulating valve in the air pump, and controls the air inlet of the air pump to be normally open through the air path, so that the air pump runs at no load, so as to reduce power loss and protect the air pump.

When the air pressure in the air reservoir is lower than the pressure set by the regulator due to loss, the valve in the regulator valve is returned to the position by the return spring, and the control gas path of the air pump is disconnected, and the air pump starts pumping again.

Extended Materials. Main Applications:

1. Traditional aerodynamics: pneumatic tools, rock drills, air picks, pneumatic wrenches, pneumatic sandblasting.

2. Instrument control and automation devices, such as tool replacement in machining centers.

3. The vehicle brakes, and the doors and windows open and close.

4. In the air-jet loom, the weft yarn is blown with compressed air instead of the shuttle.

5. In the food and pharmaceutical industries, the slurry is stirred with compressed air.

6. Starting of large marine diesel engines.

7. Wind tunnel experiment, underground passage ventilation, metal smelting.

Find the two wires with the highest resistance among the three wires, and the other one is the common line.

With the common line resistance is small, the main winding is also the running winding.

With the large resistance value of the common wire, the secondary winding is also the starting winding.

Wiring Steps:

Connect any of the power supply wires to the common wires measured above.

The main winding, this wire is connected to the other end of the power supply and the wire at either end of the capacitor.

The last wire of the motor is connected to the secondary winding and the capacitor.

When wiring, pay attention to each terminal must be handled well by the electrician belt to avoid leakage.

It can be connected directly, and the general capacitance is the shortest two yellow or white or red wires.

Of course, the wiring method of connecting the air pump is to choose to wire from the outlet and flow out from the inlet, so as to ensure the smooth recording.

:Wiring diagram: The working principle of the air pump is: The engine drives the crankshaft of the air pump through two V-belts, thereby driving the piston to pump the air, and the gas is introduced into the air reservoir through the air duct. On the other hand, the air reservoir is connected through a trachea.

If you want to wire this air pump, you must first understand some of its rules, which are generally some things from the neutral line and the live wire. Therefore, we must understand it well, and then we will protect our safety first.

The way of wiring is relatively simple, you must connect his red and black wires.

Jiadong, how to wire the air pump? If you want to wiring, it must be connected to some kind of device, to wiring.

How to wire a mobile air pump? You can wire this according to the manual, it's very simple.

First, use a multimeter to measure whether the voltage is normal and whether the total power supply incoming line is normal.

The yellow-green wire is the ground wire (see if this wire is connected to the chassis). Two red wires and two black wires may be one of the pairs of red and black wires is the main winding, and the other pair is the secondary winding, you can use the multimeter test or other methods to determine. If so, the two black wires are connected together to connect the neutral wire, and the live wire is connected to the end of the main winding and the capacitor.

The red line at the bottom of the contactor is connected at 5L3, and the blue line is connected at 1L1 or 2L, where the juice master, point.

On the air pressure switch, connect the next two screws, and your hair extensions will not stop now.

The control loop is a normally closed contact connected to the thermal relay by one phase of the power supply, connected to the contactor coil below, and connected to another phase power supply at the outlet. The main circuit is the three-phase live wire to the upper end of the switch, then to the upper end of the contactor, the lower to the main contact of the thermal relay, then to the pressure switch, and finally to the motor.

m Hello element symbol.

Because the relay is composed of two parts, a coil and a contact group, the graphical symbol of the relay in the circuit diagram also includes two parts: a rectangular box representing the coil; A set of contact symbols represents a combination of contacts. When there are not many contacts and the circuit is relatively simple, the contact group is often drawn directly on one side of the circle, which is called centralized representation.

Electrical symbol and contact form:

The relay coil is represented by a rectangular box symbol in the circuit, and if the relay has two coils, draw two rectangular boxes side by side. At the same time, mark the word symbol "j" of the relay in or next to the rectangular box. Relays.

1. The proximity switching power supply is DC 12 volts, with three lead wires, two power lines and one output line.

2. Relay selection: coil DC 12 volts, contact AC 220 volts.

3. The solenoid valve has AC 220 volts and DC 24 volts.

Connection: The "output line" of the proximity switch controls the coil of the relay, and the contact of the relay controls the power supply of the solenoid valve.

The proximity switching power supply has AC 220 volts, two power lines and one output line.

You can consult the manufacturer who purchased the diesel generator set at that time, and the manufacturer has a good understanding of the basic parameters such as the model of the unit, and will give a reference. But for such a professional problem, it is recommended that users contact professional technicians and do not operate by themselves.

Generally, there are three wires, the yellow-green wire is grounded, and the other two can be connected casually. To be regular, the red wire is connected to the phase wire (live wire), and the blue or green wire is connected to the neutral wire.
