Problems solved by technology

[0004] At this stage, only PID control is done for pressure to ensure constant pressure output, and enter sleep when the air volume is small; but the length of sleep is not considered, and the sleep time of air compressor is relatively short (even frequent sleep and wake-up). There is a large damage to the whole machine system

Embodiment 1

[0023] This example shows a sleep control method for an air compressor:

[0024] Including the following steps:

[0025] 1) Calculate the corresponding relationship between displacement and frequency according to the rated power of the equipment and the rated displacement under pressure. The controller records the frequency when the machine is running stably and corresponds to an air consumption;

[0026] 2) The controller monitors the real-time exhaust volume of the air compressor in real time, especially the exhaust volume before the air compressor goes to sleep;

[0027] 3) The controller records and monitors the sleep time of the air compressor;

[0028] 4) When the sleep time is long, it means that the user’s gas consumption is small. When waking up, the controller will make a judgment based on the records in step 2), reduce the upper limit frequency of the air compressor’s operation to a reasonable value, and ensure the stable voltage when waking up. At the same time, ...

Embodiment 2

[0036] This example shows a sleep control method for an air compressor:

[0037] Including the following steps:

[0038] 1) Calculate the corresponding relationship between displacement and frequency according to the rated power of the equipment and the rated displacement under pressure. The controller records the frequency when the machine is running stably and corresponds to an air consumption;

[0039] 2) The controller monitors the real-time exhaust volume of the air compressor in real time, especially the exhaust volume before the air compressor is dormant;

[0040] 3) The controller records and monitors the sleep time of the air compressor;

[0041] 4) When the sleep time is short, it means that the user consumes a lot of air. When waking up, the controller will judge according to the record in step 2), increase the upper limit frequency of the air compressor to a reasonable value, and increase the exhaust volume to avoid sleep start Frequently, while ensuring the user...

Abstract

The invention discloses an air compressor sleep control method. The air compressor sleep control method comprises the following steps: a controller records an air consumption corresponding to a frequency under the condition of stable operation of a machine; the controller monitors a real-time displacement of an air compressor in real time, in particular a displacement of the air compressor before sleep; the controller records and monitors the sleep time of the air compressor; if the sleep time is long, during waking, the controller judges according to the record, and reduces the upper limit frequency of operation of the whole air compressor to a reasonable value to guarantee voltage stabilization in waking start without influencing use of users; and the air compressor enters PID adjustment according to the air consumption. The air compressor sleep control method uses matching between the displacement of the air compressor and the PID adjustment for realizing sleep control of the air compressor, reduces the sleep and waking frequency of the air compressor, reduces the damage of the air compressor, and prolongs the service life of the air compressor.

Description

technical field [0001] The present invention relates to air compression equipment control technology, in particular to the technical field of air compressor control. Specifically, it shows a dormancy control method for an air compressor. Background technique [0002] Air compressor refers to a device that converts electric energy into air kinetic energy. The use of air compressor involves all walks of life. Through the PID adjustment of the driver, it can bring the required constant pressure gas to the end user. With the continuous improvement of the level of mechanization Improvement, various industries have higher and higher requirements for the manufacturing quality and technical level of the air compressor; [0003] At present, the air compressor industry at home and abroad is going through a process of electrical control frequency conversion. This process is actually a process of improving the efficiency and saving energy of the whole machine. Because the power frequen...
