Description

Technical Field

[0001] The utility model relates to the technical field of industrial automation equipment manufacturing, in particular to an automatic start-stop voltage stabilizing device for an air compressor with a reasonable structure and reliable operation. Background Art

[0002] During the operation of the air compressor, there is a certain air supply pressure inside the pipeline. Maintaining the air supply pressure stable is very important for the stability and reliability of its operation. For example, in many occasions of use, too low air pressure will lead to production failures, and too high air pressure will cause damage to some fragile parts. The existing Chinese patent with announcement number CN210265061U discloses an air compressor, which involves the technical field of air compression and solves the problem of unstable support structure caused by air compressor vibration. The key points of its technical solution include an air compressor body, a support block fixedly connected to the bottom of the air compressor body, a shell sleeved on the bottom of the support block, and a support mechanism arranged at the bottom of the shell. With respect to the above-mentioned related technologies, it is found that the existing air compressor cannot guarantee the air supply pressure when the compressed air is insufficient or the equipment fails. Manual operation is required to start the equipment on site, and it is impossible to adjust the pressure in real time according to the supply pressure fluctuation during use. Summary of the invention

[0003] In view of the shortcomings and deficiencies in the prior art, the utility model proposes an automatic start-stop pressure stabilizing device for an air compressor which has a reasonable structure, reliable operation and can timely complete the pressure stabilizing output according to the fluctuation of the on-site working pressure.

[0004] The utility model achieves this through the following measures:

[0005] An automatic start-stop pressure stabilizing device for an air compressor comprises a pressure stabilizing component, a pressurizing component and an external pipe group, wherein the external pipe group is connected to the exhaust pipe of the air compressor, and the pressurizing component is respectively connected to the pressure stabilizing component and the external pipe group; the external pipe group comprises a connecting pipe connected to the exhaust pipe of the air compressor, the upper end of the connecting pipe is connected to a horizontally arranged transverse pressure pipe, the side of the transverse pressure pipe is connected to one end of a pressure supply pipe, a pressure gauge for monitoring pressure data is arranged on the transverse pressure pipe, one end of the transverse pressure pipe is sealed and connected to the stabilizing component via a connecting flange The pressure assembly is fixedly connected, and the other end of the transverse pressure pipe is connected to the pressure relief valve; the pressure stabilizing assembly includes a pressure stabilizing box, and the pressure stabilizing box is provided with an air intake check valve; the pressurizing assembly includes a pressurizing pipe, a matching sealing shell and a piston and a piston driving component, one end of the sealing shell is connected to the pressure stabilizing box, and the piston driving component drives the piston to reciprocate in the sealing shell to increase the pressure in the pressure stabilizing box, one end of the pressurizing pipe is connected to the pressure stabilizing box, and the other end is connected to the transverse pressure pipe in the external pipe group, and the pressurizing pipe is provided with an exhaust check valve.

[0006] The pressure stabilizing box described in the utility model includes a box shell and a partition, the partition is vertically arranged in the middle of the box shell, and the partition and the box shell are integrally formed, so that the corresponding space is separated by the partition, which is easy to cooperate with the pressurizing component to perform rapid pressurized air supply operations in the pressurizing pipe. In this process, since an air intake check valve is installed on the upper surface of the box shell and an exhaust check valve is installed on the pressurizing pipe, the air intake check valve and the exhaust check valve are set to ensure the direction of gas flowing into the box shell and being discharged from the pressurizing pipe.

[0007] In the pressurizing component of the utility model, a sealing shell is sealed and fixed on the box shell of the pressure stabilizing box, a piston is slidably installed in the sealing shell, and a piston driving component drives the piston to reciprocate in the sealing shell, so as to quickly pressurize the gas in the pressurizing tube. The piston driving component includes a motor, an eccentric disk and a linkage rod. The motor is fixedly installed in the sealing shell, the eccentric disk is installed at the output end of the motor, and the eccentric disk is connected to the piston through a linkage rod. When in use, the eccentric disk is driven to rotate by the motor, and then the eccentric disk can drive the piston to reciprocate through the linkage rod.

[0008] The utility model is also provided with a PLC controller connected to the motor and the pressure gauge, so as to monitor the pressure in the outer pipe group in real time through the pressure gauge, and start the pressurizing component in time to pressurize and stabilize the pressure.

[0009] When the utility model is working, it is installed at the output end of the exhaust pipe of the air compressor, and the size of the exhaust pressure of the air compressor is monitored in real time through a pressure gauge. When the pressure is too high, the pressure can be quickly released through the pressure relief valve in the external exhaust pipe group. When it is monitored that the pressure in the pipeline is too low, the motor can be started to drive the piston to reciprocate quickly in the sealing shell, so that the pressurized air is sent from the pressure pipe to the external exhaust pipe group. In this way, the purpose of automatic pressure stabilization can be achieved during use, ensuring that the air pressure of the air compressor 1 can be stably output.

[0010] Compared with the prior art, the utility model has the remarkable advantages of reasonable structure, stable operation, and the ability to start voltage stabilization in time according to output pressure fluctuations. BRIEF DESCRIPTION OF THE DRAWINGS
