How to adjust the atmospheric pressure of the air compressor pressure switch

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.

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.

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.

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.

There are two kinds of pressure adjustment of the press, one is that the pressure difference is fixed by the switch itself, and only the automatic shutdown pressure is adjusted, and the maximum pressure is adjusted. This kind of knob with two flathead screwdrivers on the switch is debugged, and the two knobs must be adjusted consistently (otherwise they will stop when they move together, stop and start again, and burn out the electrical appliances.) The other is a regulating starting pressure (low pressure) and a regulating machine pressure, which is not easy to adjust compared to the previous one.

According to the information you provided, I found out that generally speaking, there will be a switch at the top of the air compressor that can be rotated, turning up is to increase the pressure, and turning down is to adjust the pressure. This is the specific adjustment method, but the adjustment method of different brands of air compressors is also different, you can take a look at the manual, there will be a specific operation process on it, if it is a resettable type of spring, then there should be something at the top that can rotate, turn up to increase the pressure, turn down to adjust the pressure. I hope my answer is helpful to you, oh dear.

Hello, I am helping you to inquire about the relevant information and will reply to you immediately.

How to adjust the starting air pressure of an air compressor? Hello dear, air compressor starting pressure adjustment method: the air pressure of the air compressor rotates the pressure adjustment screw clockwise, and the closing and disconnecting pressure increases synchronously.

Rotate the pressure adjustment screw counterclockwise, and the closing and disclosing pressure are reduced synchronously. If it is a resettable type of spring, then there should be something at the top that can rotate the bridge, turn up to increase the pressure, and turn down to adjust the pressure. Tighten the screws on the top of the safety valve, but you can't tighten it all at once, but you have to adjust it slowly, but it's very dangerous.

The safety pressure of the safety valve is adjusted by the local technical supervision department, and it is recommended to ask a special person to come and adjust it. I hope it can help you. If my answer is helpful to you, please give a thumbs up (in the lower left corner), I look forward to your like, your efforts are very important to me, and your support is also the motivation for my progress.

Finally, I wish you good health and a good mood!

**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.
