Technical Field

The invention belongs to the technical field of pneumatic power of air compressors, and particularly relates to an air pressure and airflow control method of an air compressor.

Background

According to the requirements of pneumatic elements of concrete mixing stations, each set of concrete mixing station is provided with one set of air compressor, one or more air storage tanks are arranged beside the air compressor of each set of mixing station, the air pressure airflow consumption of the mixing station is large, generally, the air compressor of the whole set of mixing station is started under the condition that no air pressure airflow exists, the air compressor needs to be started for waiting for the air pressure airflow to meet the production requirements of the mixing station, and according to the air compressor power of each mixing station and the volume condition of the air storage tanks, the air compressor is started in advance for about 5 to 20 minutes to meet the air pressure airflow requirements of a production line of the mixing station. The production line of the mixing station is just started and the air compressor is just started unless an operator just arrives at the operation room. The tanker driver and the mixing plant dispatch are willing to wait for a while. The production is paused for a certain time period in the middle of production, tens of minutes or hours can be scheduled or a driver can not wait for a few minutes until the air compressor starts to pump air from 0 to produce and pump materials. The existing mixing plant production line is generally characterized in that an operator on duty starts an air compressor, and the air compressor is turned off when the operator is off duty, or the air compressor is not turned off for 24 hours, and an air passage always keeps enough air pressure.

The air compressor is provided with an air pressure switch at present, the air pressure switch can automatically control the air compressor to be automatically started according to the lower air pressure inside the air compressor, and the air compressor is automatically stopped according to the increase of the internal air pressure to a certain limited air pressure.

Because the production line of the mixing plant has large air pressure airflow consumption and long air path, the mixing plant has a plurality of air pipes and air pipe joints. The gas circuit is too long, connect too much, just it is difficult to guarantee all gas circuits leak tightness, the gas circuit phenomenon of leaking often appears in the stirring station itself of nature, it is the maintenance worker that needs to change the maintenance to appear seriously all, the gas circuit leaks a small amount, or before not finding, the stirring station still can be in normal production during normal production. The air compressor can continuously rotate or the intermittent stop time of the air compressor is shortened due to a little air leakage phenomenon at the position of a pipeline or a joint. During the production of the stirring station is suspended, air pressure airflow leaks from the stirring station, when the air pressure is low, the air compressor can be automatically started, and the operation is stopped until the air pressure of the air pressure switch is on line, so that the operation is repeated, and the leaked air pressure airflow brings some pressure to the air compressor according to the production suspension time of the stirring station. The power, air source or air compressor consumed by abnormal production is abraded in operation or the abrasion of the air path is influenced, and the air path control method can reduce the consumption.

The service life of the air compressor should be such that the longer the service life the greater the consumption, the shorter the intermittent stop time, and the more frequent the consumption of the operating time. The stirring station needs the atmospheric pressure air current during normal production and certainly has not thick and can't be very, and the use of present stirring station air compressor machine says, and during the production of stirring station, air compressor has generated heat but can also the operation compressed air, and the stirring station will let the air compressor machine continue the operation, unless the air compressor machine goes wrong, can not the compressed air, just can stop.

According to the invention, the electromagnetic valve is arranged on the air supply pipeline of the mixing station of the air compressor outlet air storage tank, the electromagnetic valve is controlled on the center console, and the electromagnetic valve is closed when the production of the mixing station is suspended, so that the reduction of air pressure leakage can be ensured. The air compressor and the air storage tank are full in air pressure, and the air compressor cannot be automatically started by a pressure switch when the air compressor has the air pressure. When the mixing plant needs to produce, the electromagnetic valve is opened, and the air compressor and the air storage tank store air pressure, so that the requirement of the mixing plant for producing air pressure and air flow can be met instantly.

The invention can achieve the effect of saving the air source, the air compressor can reduce the starting frequency, achieve the effect of reducing the starting frequency of the air compressor and can save the power supply, the air compressor can not load and scald even more even if the starting frequency of the air compressor is reduced, and can improve the service life of the air compressor, and meanwhile, the soft connecting air pipes of the mixing station can also reduce the time that the air pressure is fullest and can be short, and meanwhile, the soft connecting air pipes of the mixing station can also achieve the phenomenon that the air pipes can not be broken.

The air pressure of the whole mixing plant is the maximum during the production pause of the concrete mixing plant, the phenomenon of air pipe rupture of the mixing plant is generally the production pause of the mixing plant, and the air compressor is not powered off, and the air pressure of the whole mixing plant reaches the highest period and lasts for the highest period.
