Description
Technical Field
[0001] This utility model relates to the field of compression equipment technology, and in particular to a remotely authorized compression device. Background Technology
[0002] Compressors, as widely used industrial equipment, are primarily used to compress low-pressure gases into high-pressure gases to reduce gas volume, serving as a pneumatic power source or achieving energy conversion. In practical use, to avoid the leakage of core parameters and to prevent compressors from being over-limited during operation, which could lead to equipment damage or safety accidents, manufacturers typically limit the operating range of compressors to the equipment's limits. Users can only adjust the equipment's operation and view limited operating parameters within this range. However, some users, when adjusting production lines, improving processes, or replacing upstream or downstream equipment, actually have a need to view detailed compressor operating parameters, and the testing process may require the compressor to operate beyond the preset operating range.
[0003] Most existing compressors operate based on code burned into a control board, with the operating range set in the code at the factory. For applications requiring operation outside this range, either the manufacturer needs to send technicians with specialized equipment to assist the user in debugging the compressor, or the manufacturer needs to design a custom control board to replace it. It's easy to see that both sending technicians to the site and designing a custom control board suffer from low timeliness and excessively high labor or design costs, making it difficult to meet user needs. Utility Model Content
[0004] This embodiment discloses a remotely authorized compression device, specifically including:
[0005] A frequency converter 200 mounted on a bracket 100, and an operation panel 300 electrically connected to the frequency converter 200;
[0006] The variable frequency drive 200 drives the motor 400 to operate, and the motor 400 drives the linked compressor body 500 to operate.
[0007] The compressor body 500 draws in room temperature gas under negative pressure through the intake valve 510. The room temperature gas mixes with the high temperature lubricating oil inside the body to form a high temperature oil-gas mixture and is output to the oil-gas separator 600.
[0008] The top of the bracket 100 is equipped with a cooler 800, and the oil-gas separator 600 separates the high-temperature oil-gas mixture into high-temperature lubricating oil and high-temperature gas, which are then injected into the cooler 800 respectively.

[0010] As an optional implementation, the operation panel 300 is used to input control commands for the compressor body 500;
[0011] The variable frequency drive 200 adjusts the output current parameters based on the control command, and controls the compressor body 500 by frequency conversion.
[0012] As an optional implementation, the operation panel 300 is also used to monitor and display operating parameters or permission parameters;
[0013] The access parameters include exhaust pressure, exhaust temperature, oil separator differential pressure, oil separator inlet pressure, water inlet pressure, water inlet temperature, oil injection pressure, oil injection temperature, air tank pressure, air tank temperature, motor winding temperature, motor bearing temperature, tank temperature, unit vibration value, motor rated current, motor current imbalance, motor overload delay, fan rated current, fan current imbalance, fan overload delay, oil cut-off delay, pressure maintaining valve opening pressure, power supply negative sequence judgment threshold, CT1 current transformer ratio, CT2 current transformer ratio, fault filtering time, phase sequence protection time, phase loss protection time, and operating limit.
[0014] As an optional implementation, the operation panel 300 is used to display the permission parameters when a correct dynamic authorization code is received;
[0015] The dynamic authorization code is dynamically generated by the cloud server based on the user information, time information, and device information carried in the authorization request.
[0016] As an optional implementation, the oil-gas separator 600 centrifugally separates high-temperature oil-gas mixtures;
[0017] The high-temperature lubricating oil condenses on the inner wall of the oil-gas separator 600 and flows down, and is output below the oil-gas separator 600;
[0018] The high-temperature gas is output above the oil-gas separator 600.
[0019] As an optional implementation, the intake end of the intake valve 510 is equipped with an intake filter 520, through which ambient temperature gas is drawn.
[0020] As an optional implementation, the cooler 800 includes a cooling grille 810, a fan blade 820 mounted below the cooling grille 810, and a fan blade motor 830 for driving the fan blade 820 to rotate.
[0021] As an optional implementation, the cooling grille 810 is used to increase the heat dissipation area of the lubricating oil pipe 610 and the gas pipe 620, and the fan blade motor 830 drives the fan blade 820 to rotate, blowing and cooling the cooling grille 810.
[0022] As an optional implementation, the high-temperature gas is cooled down by the cooling grille 810 to form cooling gas, which is discharged from the exhaust port 840 at the top of the cooling grille 810;
[0023] The high-temperature lubricating oil is cooled down by the cooling grille 810 to form cooling lubricating oil, which is then recirculated into the machine body.
[0024] Compared with the prior art, this embodiment has the following beneficial effects:
[0025] The compression equipment filters and separates the input gas, while the lubricating oil and gas are simultaneously cooled in a cooler. The cooled lubricating oil is then returned to the equipment for continued use. When a user needs to view the compression equipment's access parameters, they can send an authorization request to the cloud server via the control panel. After verifying the authorization request, the equipment manufacturer generates and notifies the user of a dynamic authorization code. The user then enters the dynamic authorization code on the control panel to obtain access to the access parameters. This process can be performed remotely, eliminating the need for on-site technical personnel or additional control board design. It is highly efficient, significantly reducing labor and design costs, and meeting users' higher-level usage needs for the compression equipment. Attached Figure Description

[0033] The technical solutions in this embodiment will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0034] Please see Figures 1-4 This embodiment discloses a remotely authorized compression device, comprising:
[0035] A frequency converter 200 mounted on a bracket 100, and an operation panel 300 electrically connected to the frequency converter 200;
[0036] The frequency converter 200 drives the motor 400 to run, and the motor 400 drives the compressor body 500 to run.
[0037] The compressor body 500 draws in room temperature gas under negative pressure through the intake valve 510. The room temperature gas mixes with the high temperature lubricating oil inside the body to form a high temperature oil-gas mixture, which is then output to the oil-gas separator 600.
[0038] The top of the bracket 100 is equipped with a cooler 800 and an oil-gas separator 600 to separate the high-temperature oil-gas mixture into high-temperature lubricating oil and high-temperature gas, which are then injected into the cooler 800 respectively.
[0039] The operation panel 300 communicates with the cloud server to output authorization requests and to input dynamic authorization codes corresponding to the authorization requests.
[0040] In this embodiment, the frequency converter 200 is controlled by the control commands received by the operation panel 300. Correspondingly, the operating parameters of the frequency converter 200 and other components are also fed back to the operation panel 300 for monitoring.
[0041] Under normal circumstances, the operation panel 300 only allows users to view conventional operating parameters such as exhaust pressure, exhaust temperature, oil separator differential pressure, oil separator pre-pressure, inlet water pressure, inlet water temperature, injection pressure, injection temperature, air tank pressure, air tank temperature, motor winding temperature, motor bearing temperature, and tank internal temperature. However, when users adjust production lines, improve processes, or replace equipment, the reference value provided by the above operating parameters is insufficient to complete higher-level operations beyond operation. In this case, the user sends an authorization request to the cloud server through the operation panel 300.
[0042] Furthermore, the compression equipment manufacturer learns the user's needs through the cloud server, and then generates a corresponding dynamic authorization code based on the authorization request. The user is then informed of the dynamic authorization code. After entering the dynamic authorization code on the operation panel 300, the user can view more detailed permission parameters and gain greater freedom in debugging.
[0043] In this embodiment, the operation panel 300 is used to input control commands for the compressor body 500;
[0044] The variable frequency drive 200 adjusts the output current parameters based on control commands, and the variable frequency control compressor body 500.
[0045] Specifically, the compressor body 500 is controlled by the frequency converter 200. Therefore, by adjusting the current parameters output by the frequency converter 200, the operating performance of the core compressor body 500 can be controlled.
[0046] As an optional implementation, the operation panel 300 is also used to monitor and display operating parameters or permission parameters;
[0047] The access parameters include exhaust pressure, exhaust temperature, oil separator differential pressure, oil separator inlet pressure, water inlet pressure, water inlet temperature, oil injection pressure, oil injection temperature, air tank pressure, air tank temperature, motor winding temperature, motor bearing temperature, tank temperature, unit vibration value, motor rated current, motor current imbalance, motor overload delay, fan rated current, fan current imbalance, fan overload delay, oil cut-off delay, pressure maintaining valve opening pressure, power supply negative sequence judgment threshold, CT1 current transformer ratio, CT2 current transformer ratio, fault filtering time, phase sequence protection time, phase loss protection time, and operating limit.
[0048] As an optional implementation, the operation panel 300 is used to display permission parameters when the correct dynamic authorization code is received;
[0049] The dynamic authorization code is dynamically generated by the cloud server based on the user information, time information, and device information carried in the authorization request.
[0050] In this embodiment, based on the sensor data and current parameters collected during the operation of each component, the operation panel 300 displays the operating parameters and, after the customer enters the correct dynamic authorization code, displays the corresponding permission parameters. This allows compressor manufacturers to effectively control the core parameters of the equipment, and users can obtain data support when there is a practical need.
[0051] As an optional implementation, the oil-gas separator 600 centrifugally separates high-temperature oil-gas mixtures;
[0052] High-temperature lubricating oil condenses on the inner wall of the oil-gas separator 600 and flows down, exiting from below the oil-gas separator 600;
[0053] High-temperature gas is output above the oil-gas separator 600.
[0054] Here, oil-gas separation is carried out first at high temperature. The gas has higher activity properties and is easier to separate from the droplet-like lubricating oil.
[0055] As an optional implementation, an intake filter 520 is installed at the intake end of the intake valve 510 to draw ambient temperature gas from the current environment.
[0056] Here, the oil-gas mixture is filtered before entering the compressor body 500 to avoid impurities damaging downstream components.
[0057] As an optional implementation, the cooler 800 includes a cooling grille 810, a fan blade 820 mounted below the cooling grille 810, and a fan blade motor 830 for driving the fan blade 820 to rotate.
[0058] The cooling grille 810 is used to increase the heat dissipation area of the lubricating oil pipe 610 and the gas pipe 620. The fan motor 830 drives the fan blade 820 to rotate and blow on the cooling grille 810 to cool it down.
[0059] In this embodiment, the lubricating oil pipe 610 and the gas pipe 620 are coiled inside the cooling grid 810 to increase the contact area with the gas grid and improve heat dissipation efficiency.
[0060] In this embodiment, the high-temperature gas is cooled down by the cooling grille 810 to form cooling gas, which is discharged from the exhaust port 840 at the top of the cooling grille 810.
[0061] The high-temperature lubricating oil is cooled down by the cooling grille 810 to form cool lubricating oil, which is then returned to the machine body.
[0062] Here, cooling gas is used for industrial applications, and cooling lubricating oil is returned to the supply end of the equipment for circulation, thus performing lubrication and heat dissipation.
[0063] As an optional implementation, the operation panel 300 includes at least a touch display screen 310 and an emergency power-off switch 320.
[0064] In this embodiment, the touch display screen 310 provides a virtual keyboard while displaying parameters, allowing users to input control commands and dynamic authorization codes, thus eliminating the need for numerous additional control buttons.
[0065] The emergency power-off switch 320 is used to immediately cut off the power supply to all equipment in an emergency.
[0066] Here, the compression equipment filters and compresses the input gas, while the lubricating oil and gas are simultaneously cooled in a cooler. The cooled lubricating oil is then returned to the equipment for continued use. When a user needs to view the compression equipment's access parameters, they can send an authorization request to the cloud server via the control panel. After verifying the authorization request, the equipment manufacturer generates and notifies the user of a dynamic authorization code. The user then enters the dynamic authorization code on the control panel to obtain access to the access parameters. This process can be performed remotely, eliminating the need for on-site technical personnel or additional control board design. It is highly efficient, significantly reducing labor and design costs, and meeting users' higher-level usage needs for the compression equipment.
