There are two screws on the pressure switch of the air compressor, one is used to adjust the upper limit of pressure, and the other is used to adjust the lower limit of pressure。Turn it up clockwise, turn it down anticlockwise。The specific pressure adjustment size of the air compressor is as follows:
1, if it is a resettable type of spring, then there should be a thing at the top that can rotate, turn up to increase the pressure, turn down to reduce the pressure。
2, screw down the top of the safety valve, but not only tighten one circle, slowly adjust。But it's dangerous。3、The safety pressure of the safety valve shall be adjusted by the local technical supervision department。
Generally speaking, air compressors start automatically at low pressure and stop automatically at high pressure。After entering the air compressor control module, you can find the parameter Settings and then enter the pressure regulation。It should be noted that because the pressure of the air compressor is set by the factory, it belongs to the manufacturer's parameters, so if you want to adjust the pressure, you need to have the manufacturer's password。The reason for this is to prevent air compressor failure and shutdown caused by user misoperation, and to protect the air compressor head and oil and gas separation barrel。The configuration of the 10 kg air compressor and the 8 kg air compressor is slightly different。Therefore, if you want to adjust the pressure from the factory to 10 kg air compressor, it is not possible。But it's okay to keep the pressure down。However, it must be carried out under the guidance of professional personnel, otherwise the air compressor is easy to fail!The air compressor automatically starts at low pressure and stops at high pressure。Whether it is a piston or a screw, 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, just adjust the range of the pressure switch and the starting pressure set above the sensor。Pressure switches have a range and DIFFE。Adjust the range as needed, and the differential usually does not move。If the pressure sensor is to be adjusted, it only adjusts the set start-stop pressure value, not the pressure sensor itself。If there is a display panel above the air compressor, there is usually a set pressure where the values are adjusted to change the start and stop pressures。There are two kinds of pressure regulation for air compressors。One is that the pressure difference is fixed by the switch itself, which only adjusts the automatic stop pressure and the maximum pressure。There are two flat head screwdriver debugging knobs on the switch, both knobs must be adjusted in the same way (otherwise they will move together to stop, stop and start, burning electrical equipment)。The other is the starting pressure (low pressure) and the stopping pressure (high pressure), which is not easy to adjust compared to the former
When commissioning the air compressor in the factory, adjust to the specified pressure according to the customer's needs, and then set the pressure difference。For example, a compressor starts pumping gas to an air storage tank。When the pressure is 10kg, the air compressor will be stopped or unloaded。When the pressure is 7kg, the air compressor will start again。Different air compressor switches have different adjustment methods。One is that the pressure difference is fixed by the switch itself, and only the automatic stop pressure is adjusted, that is, the z* high pressure。There are two flat-head screwdriver debugging knobs on the switch, and both knobs must be adjusted in the same way, otherwise they will move together to stop, stop and start, burning electrical equipment。The other is adjustable starting pressure (low pressure) and adjustable stopping pressure (high pressure).。
Air compressor pressure regulation:
1, turn the pressure adjustment screw clockwise, while increasing the closing and disconnecting pressure。
2. Rotate the pressure adjusting screw counterclockwise to reduce the closing and disconnecting pressure。
Air compressor differential pressure regulation:
1. Rotate the differential pressure adjustment screw clockwise to keep the closing pressure constant and increase the breaking pressure。
2. Rotate the differential pressure adjustment screw counterclockwise to keep the closing pressure unchanged and the disconnecting pressure reduced。
The above is about how to adjust the pressure of the air compressor pressure switch。Introduces how to adjust the pressure of the air compressor, the air compressor is best equipped with a pressure gauge, so that you can know which is the upper limit, which is the lower limit, need to adjust how much。There is a combination of AC contactors to achieve the automatic effect of the pressure switch。
