Air compressor with multiple motors

An air compressor, especially an air compressor that is small and has a plurality of motors.

According to the general air compressor, it is widely used in various fields of industrial production. It is a general-purpose mechanical device. The piston air compressor is mainly composed of a cylinder, a piston, a piston rod, a crank slider mechanism, a gas storage tank and a motor. The motor drives the crank to rotate, so that the crank drives the slider to reciprocate through the connecting rod, and the slider drives the piston inside the cylinder to reciprocate to inhale and compress the air through the piston rod, and the compressed air is pressed into the air tank. Storage; when the air pressure in the air tank reaches 0.7MPA, the motor will stop, and when the compressed air is output, the air pressure in the air tank will gradually decrease, and the pressure of the compressed air output will also become lower; When the pressure in the gas tank drops to 0.5-0.6MPA, the motor will restart and the pressure in the gas tank will be replenished to 0.7MPA. Therefore, the air compressor of this structure often needs motor starting during use. Inflating the air, the motor is used more frequently. In addition, this air compressor is only equipped with one motor. The long-term use of gas will cause the motor to continue working without stopping for a long time, so that the motor The service life is shortened, and sometimes when the gas consumption is large, the rate of replenishing gas will not keep up with the speed of gas consumption.

Improve the service life of the motor.

The following is a specific embodiment of the present invention and further describes the technical solution of the present invention with reference to the accompanying drawings, but the present creation is not limited to the embodiments.

Referring to the first figure, it can be clearly seen from the figure that the air compressor having a plurality of motors includes a control system, a gas storage tank 13 and a motor 12.

The number of the motors 12 is at least two, and each of the motors 12 corresponds to a set of compression mechanisms. The motor 12 inputs compressed gas into the air reservoir 13 through a compression mechanism, and each of the motors 12 is controlled by the control system. In the illustrated embodiment, there are five motors 12, including one main motor and four sub motors, and the control system is disposed on the main motor.

The control system has a drive controller, a pressure detector 2 and a computer. The pressure detector 2 is electrically connected to the computer controller. The pressure detector 2 is used for detecting the pressure value in the gas storage tank 13. The computer calculates the continuous working time of the motor 12 in various working states.

Referring to the second figure, as is clear from the figure, the compression mechanism has a cylinder 1, a slider 9 and a crank 10, and the motor 12 drives the crank 10 to rotate, and the motor 12 is a brushless motor 12, The cylinder of the cylinder 1 is provided with an air inlet 3 and an exhaust port 4 communicating with the inner cavity of the cylinder. The intake port 3 is provided with an intake valve 5, and the exhaust port 4 is provided with an exhaust valve 6, and the cylinder The inner cavity is provided with a piston 7 and a piston rod 8. One end of the piston rod 8 is connected with the piston 7, the other end is connected with the slider 9, and the slider 9 is provided with a connecting rod 11 with respect to the other side of the piston rod 8. The two ends of the 11 are respectively rotatably connected to the slider 9 and the crank 10.

During operation, the pressure detector 2 detects the pressure state in the gas storage tank 13 at any time. When the compressed air is output, the air pressure in the gas storage tank 13 is gradually reduced, and when the pressure value in the gas storage tank 13 is lowered to a setting When the value is set, the drive controller selects the corresponding number of motors 12 according to the amount of gas to be replenished and the magnitude of the pressure drop. When the gas to be replenished is large or the output flow of the compressed air is large, the drive controller will start. A larger number of motors 12 work at the same time to ensure that the gas is replenished in a short time and the continuous output of the compressed air is satisfied, while other unstarted motors 12 are reserved to achieve an effect of improving the efficiency of the air supply; When the additional gas is less or the output flow of the compressed air is small, the drive controller only needs to start a smaller number of motors 12 to operate.

When the motor 12 continues to work for a set time, the drive controller will start the standby motor 12 to operate, and the motor 12 that has reached the set working time is stopped, so that the newly activated motor 12 and the motor 12 for a period of time are paired. As soon as the transfer replacement is performed, the same motor 12 is prevented from working for a long time, and the accumulated working time of all the motors 12 is balanced as much as possible to achieve the effect of improving the service life of the motor 12.

When the output of the compressed air fluctuates, the drive controller can also adjust the number of working motors 12 in time to shut down part of the motor 12 or temporarily increase the manner of starting a part of the spare motor 12 to control the pressure value in the air tank. Always at a steady value, the air pressure of the output is relatively stable.
