How to adjust the pressure switch of the air compressor.

There are two knobs on the pressure switch, one is the upper limit of pressure regulation, and the other is the lower limit of pressure regulation. The clockwise hand is addition, and the counterclockwise is subtraction. It is best to have a pressure gauge on the air compressor, so that you can know which button you adjust is the upper limit, which is the lower limit, and how much.

In addition, it is necessary to use it in combination with AC contactors to achieve the automatic effect of pressure switching.

An air compressor is a device used to compress gas. An air compressor is similar to a water pump. Most air compressors are reciprocating piston type, rotating vanes or rotating screws. Centrifugal compressors are very large applications.

According to the working principle, it can be divided into three categories: volumetric type, power type (speed type or turbine type), and thermal compressor.

According to the lubrication method, it can be divided into oil-free air compressor and oil-lubricated air compressor.

According to the performance, it can be divided into: low noise, variable frequency, explosion-proof and other air compressors.

There are many more categories, which you can look up for yourself.

This is not a pressure switch.

This is the capacitive valve, which can control and adjust the intake volume of the intake valve.

Air compressor pressure switch pressure adjustment method:1. Adjust the pressure of the air compressor. Rotate the pressure adjustment screw clockwise, and the closing and disclosing pressure increase simultaneously. Rotate the pressure adjustment screw counterclockwise, and the closing and disclosing pressure are reduced synchronously.

2. Differential pressure adjustment. Rotate the differential pressure adjustment screw clockwise, the closing pressure remains unchanged, and the disconnection pressure increases. Rotate the differential pressure adjustment screw counterclockwise, the closing pressure remains unchanged, and the disconnection pressure decreases.

Air pressure regulating valve of air compressor air pressure regulation method: there are two small screws, one is to adjust the lowest pressure, and the other is to adjust the pressure difference.

Lowest pressure: This is the lowest starting pressure; Let's say startup.

Pressure difference: For example, now it is start-to-stop, and if you press tightly, you can adjust it to start-to-stop.

Pay attention to the method when adjusting, remember to cut off the power immediately if something happens, so that it is the safest.

The lower one is the lowest working pressure, and the higher one is the highest pressure.

The air compressor stops working, (first loosen the higher one) and starts to adjust the minimum pressure, adjust to start, if you don't dare, adjust some.

Turn it to the highest level, that is, let it work, almost to the highest pressure you need, you relax the highest pressure, stop it as soon as it arrives, and the operation should be careful.

The two knobs are synchronized, the first one is adjusted as much as you want, and the second one is also adjusted as much as you want. There is no measurement to be adjusted against the barometer. After starting, observe the barometer, record the number of meters when the machine stops, adjust the knob according to the required air pressure, exhaust, record the number of meters when the machine starts and stops the machine, and then adjust, exhaust.

Repeat the adjustment to the desired working state.

**The 2 screws side by side below are the pressure adjustment, the adjustment needs to be basically synchronized, the pressure switch will stop when it reaches the target pressure, and it will not start according to the length of time, but will start according to a certain value of pressure drop; It will only be activated if the target pressure drop is about 2, and the starting value of the pressure drop is related to the magnitude of the target pressure value.

There should be a knob (or a tool) on the pressure switch and the value and direction should be marked. So adjust it as needed.

Generally speaking, the air compressor is automatically started at low pressure and stopped automatically at high pressure. I don't know what kind of air compressor yours looks like, piston or screw. But in either case, there is usually a pressure switch or pressure sensor to achieve automatic control.

Therefore, if you need to adjust the pressure of the air compressor, you only need to adjust the action range of the pressure switch and the starting pressure set on the sensor. The pressure switch has a range and a diffeThe range can be adjusted as needed, and the diffe is generally not moving.

If the pressure sensor is to be adjusted, only the set start-stop pressure value is adjusted, not the pressure sensor itself. If there is a display panel on the air compressor, there is generally a set pressure, in which the value is adjusted to change the start-stop pressure.

They are the two spirals that regulate the upper and lower limits of the pressure. The pressure switch sometimes makes up the energy to close the load reduction valve, and it is necessary to look at the site to draw conclusions. It's hard to judge here.

Is it a screw compressor or a reciprocating one?

Although we do not have the same method of adjusting different brands for air compressors, but they are similar, the following is a subdivision of the parts of the air compressor, as long as you find the relevant parts of the air compressor, you can adjust it according to the following methods. Let's move on!

In general, when we debug before use, the system adjusts to the specified pressure according to the air consumption required by the user, and then sets a pressure difference.

For example, the air compressor starts to run the work, pumps air to the gas tank, unloads naturally when the pressure reaches 10kg, and starts to run again when the pressure drops below 7kg. There is a pressure difference between this, and this process allows the machine to rest for a short time, thus achieving the effect of protecting the machine. It even saves some of the electricity consumption costs for enterprises.

Different air compressor brand switches have different adjustment methods, which are usually divided into two types:

1. The differential pressure is fixed by the switch itself, and only the automatic unloading pressure is adjusted and the pressure is increased. There are two knobs for slotted screwdriver debugging on the switch, and the two knobs need to be adjusted consistently, otherwise they will stop as soon as they start, and the cyclic ups and downs will cause serious consequences of burning out the motor.

2. One adjusts the starting pressure (low pressure) and adjusts the unloading pressure (high pressure).

3. Air compressor pressure adjustment

1. Rotate the pressure adjustment screw clockwise, and the closing and disconnecting pressure increase at the same time.

2. Rotate the pressure adjustment screw counterclockwise, and the closing and disconnecting pressure are reduced synchronously.

Fourth, the differential pressure adjustment of the air compressor:

1. Rotate the differential pressure adjustment screw clockwise, the closing pressure remains unchanged, and the disconnection pressure becomes larger.

2. Rotate the differential pressure adjustment screw counterclockwise, the closing pressure remains unchanged, and the disconnection pressure decreases.
