A device for monitoring the operation of a centrifugal compressor

Abstract

This utility model relates to the technical field of monitoring centrifugal compressor operation devices, and more particularly to a monitoring centrifugal compressor operation device, including a monitoring instrument body. The left and right sides of the monitoring instrument body are symmetrically equipped with fixing components, and a mounting plate is provided on the rear side of the monitoring instrument body. By setting the fixing components on the monitoring centrifugal compressor operation device, during installation, the snap-fit ​​plate is snapped into the snap-fit ​​groove. Rotating the adjustment knob drives the threaded rod to rotate, and the threaded rod drives the adjustment block to move. When the adjustment block moves rearward, it drives the fixing rod to move outward via an auxiliary rod. When the fixing rod moves into the fixing hole, the monitoring instrument body is installed. When the adjustment knob is rotated in the opposite direction, and the fixing rod moves to the outside of the fixing hole, the monitoring instrument body can be disassembled. Installation and disassembly are relatively convenient, so that when the monitoring instrument body is damaged, it can be disassembled for repair or replacement.

Description

Technical Field

[0001] This utility model relates to the technical field of monitoring centrifugal compressor operation devices, specifically a monitoring centrifugal compressor operation device. Background Technology

[0002] Centrifugal compressors are key equipment widely used in industries such as petroleum, chemical, power, and metallurgy. Their operating status directly affects the stability and safety of the entire production system. During actual operation, centrifugal compressors are susceptible to various factors, such as fluctuations in inlet temperature and pressure, bearing wear, and impeller failure. These factors can lead to problems such as decreased compressor efficiency, increased vibration, and excessively high temperatures. If these issues are not detected and addressed promptly, they can range from affecting production schedules to causing equipment damage and production accidents, resulting in significant economic losses and safety hazards.

[0003] Existing centrifugal compressor monitoring devices are inconvenient to install and disassemble, and when the monitoring device is damaged, it is inconvenient to disassemble it for repair or replacement.

[0004] Therefore, a device for monitoring the operation of centrifugal compressors is needed to improve the above-mentioned problems. Utility Model Content

[0020] In this invention, a fixing component is installed on the centrifugal compressor operating device. During installation, the snap-fit ​​plate is snapped into the snap-fit ​​groove. Rotating the adjustment knob drives the threaded rod to rotate, which in turn moves the adjustment block. When the adjustment block moves backward, the fixing rod moves outward via the auxiliary rod. Once the fixing rod is inside the fixing hole, the monitor body is installed. When the adjustment knob is rotated in the opposite direction, the monitor body can be disassembled once the fixing rod moves to the outside of the fixing hole. Installation and disassembly are convenient, and when the monitor body is damaged, it can be disassembled for repair or replacement. Attached Figure Description

The snap-fit ​​seat 102 has a snap-fit ​​groove 103 inside. The snap-fit ​​plate 101 is correspondingly and adapted to the snap-fit ​​groove 103, so that the snap-fit ​​plate 101 can be snapped into the inside of the snap-fit ​​groove 103, so that it can limit the position of the monitor body 1.

[0032] Mounting holes are provided at the corners of the front of the mounting plate 3. The fixing frame 4 is U-shaped. The inner side of the connecting frame 201 is fixedly connected to the left and right sides of the monitoring body 1. The connecting frame 201 is adapted to the fixing frame 4. A threaded block is provided on the front side inside the connecting frame 201. The threaded block is adapted to the threaded rod 202 and has a threaded hole. The threaded rod 202 is threadedly connected to the threaded hole. The outer wall of the adjusting knob 203 is evenly provided with anti-slip texture. When the adjusting knob 203 is rotated, it can drive the threaded rod 202 to move. The anti-slip texture increases the friction with the hand, making it more stable when rotating.

[0033] The adjusting block 204 is arranged in an isosceles trapezoidal structure, with the length of the rear end of the adjusting block 204 being shorter than the length of the front end.

[0035] The working process of this utility model is as follows: Using the centrifugal compressor monitoring device designed in this scheme, a fixing component 2 is installed on the monitoring centrifugal compressor operating device. The mounting plate 3 is installed at the required position through the mounting hole. Then, the snap-fit ​​plate 101 is snapped into the snap-fit ​​groove 103. Next, the adjusting knob 203 is rotated. When the adjusting knob 203 rotates, it drives the threaded rod 202 to rotate. When the threaded rod 202 rotates, it drives the adjusting block 204 to move. When the adjusting block 204 moves backward, it presses against the auxiliary rod 212. The auxiliary rod 212 drives the first connecting plate 206 and the second connecting plate 208 to move. When the first connecting plate 206 and the second connecting plate 208 move, they drive the fixing rod 211 to move outward. When the fixing rod 211 moves into the fixing hole 5, the monitoring device body 1 is installed. When the adjusting knob 203 is rotated in the opposite direction, and the fixing rod 211 moves to the outside of the fixing hole 5, the monitoring device body 1 can be disassembled. Installation and disassembly are relatively convenient. Therefore, when the monitoring device body 1 is damaged, it can be disassembled for repair or replacement.
