Description

Technical Field

[0002] The centrifugal compressor base is used to fix the working motor and centrifugal disc. The impeller and other parts of the centrifugal compressor are mounted on the main shaft to form a rotor. The rotor is supported on the bearing and driven by the working motor to rotate at high speed. It is easy to vibrate when working. The centrifugal disc includes components such as the casing, partition, seal, air intake chamber and volute chamber. Fixed elements such as diffusers, bends and returners are formed between the partitions. The existing centrifugal compressor base has a large vibration amplitude when working, low working intelligence, and a complex and easy to loosen fixed working device.

[0003] The Chinese utility model patent with publication number CN 207830200 U discloses an intelligent base for a centrifugal compressor, including a base, a buckle frame and a ZCA reducer. Two symmetrically distributed buckles are provided on the top of the base, and the buckle frames are vertically arranged at the top center position of the base and are tightly fitted and fixed to the base. A ZCA reducer is provided on one side of the base, and the ZCA reducer is horizontally arranged on the side wall of the base and is fixedly connected to the base by screws. The intelligent base of the centrifugal compressor adopts support columns and fixing holes for use. Compared with traditional bases, it has a wider working range. The fixing holes can be used to fix it on some shelves to work with other devices. The support columns can also be used to raise the entire base so that the entire device can be used alone, and the limit holes are used in conjunction with the through holes.

[0004] The above-mentioned public documents cannot ensure that the loose limit position can be further locked, so that the centrifugal compressor may become loose due to vibration during operation. Therefore, a centrifugal compressor mounting base is now needed. Utility Model Content

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] The utility model provides: a centrifugal compressor mounting base, such as Figure 1-Figure 5As shown, it includes a base 1 and a mounting frame 12, a limit seat 2 is installed on the top of the base 1, a limit shell 7 is slidably installed inside the limit seat 2, a mounting plate 8 is fitted on the top of the limit shell 7, and two groups of mounting disks 11 are embedded and installed on the upper surface of the mounting plate 8; a force plate 13 is bolted and installed on the upper surface of the limit seat 2, four groups of motors 16 are symmetrically installed on both sides of the force plate 13, and a group of threaded rods 17 are key-connected and installed on the output end of each group of motors 16, and two groups of L-shaped pressure plates 18 are symmetrically and movably installed inside the force plate 13.

[0025] Preferably, the base 1 and the limit seat 2 are connected at the center and an inner groove 3 is opened, an electric push rod 4 is installed inside the inner groove 3, the limit shell 7 is a hollow structure opening downward, the telescopic end of the electric push rod 4 extends into the limit shell 7 and is bolted and installed, the inner groove 3 opened inside the base 1 and the limit seat 2 accommodates and limits the electric push rod 4 and the limit shell 7, and the limit shell 7 is pushed out by the operation of the electric push rod 4, thereby ensuring the stability of the limit shell 7 during the lifting process, making the installation of the centrifugal compressor safer.

[0026] Furthermore, an anti-skid pad 6 is embedded in the bottom of the base 1, and a group of slots 5 are respectively provided at the four inflection points on the upper surface of the limiting seat 2. The anti-skid pad 6 installed at the bottom of the base 1 reduces the vibration of the base 1 against the ground, while improving the overall vibration reduction and anti-skid properties of the device. The slot 5 provided on the upper surface of the limiting seat 2 cooperates with the force plate 13 to make the installation of the mounting frame 12 more stable, thereby improving the stability of the pressure applied by the L-shaped pressure plate 18 on the connection.

[0027] Furthermore, two groups of limiting grooves 9 are symmetrically opened on the upper surface of the mounting plate 8, and a group of vibration-damping rubber pads 10 are embedded and installed inside each group of limiting grooves 9. The two groups of mounting plates 11 are respectively embedded and installed inside a group of vibration-damping rubber pads 10, and a number of groups of threaded holes are opened through the mounting plates 11. The limiting grooves 9 opened on the upper surface of the mounting plate 8 and the vibration-damping rubber pads 10 embedded in the limiting grooves 9 are used to limit the mounting plates 11 to ensure the stability and vibration reduction of the mounting plates 11. The threaded holes opened inside the mounting plates 11 can ensure that the device can adapt to centrifugal compressors of different specifications and ensure the fixation of the installation position. The connecting end of the centrifugal compressor and the mounting plate 11 can be stably pressed by the L-shaped pressure plate 18 through the lifting and lowering of the limiting shell 7.

[0028] It is worth mentioning that a group of force plates 13 are respectively installed at the bottom end of each leg of the mounting frame 12, and each group of force plates 13 is correspondingly inserted into the internal bolts of the card slot 5 for installation. The force plates 13 are inserted into the internal bolts of the card slot 5, which can better determine the installation position of the mounting frame 12 and transmit the pressure on the mounting frame 12 to the limit seat 2 and the base 1, so that the L-shaped pressure plate 18 exerts greater pressure on the installation location of the centrifugal compressor.

The positioning columns 14 installed inside the force-bearing plate 13 and the rotating inner tubes 15 rotatably installed inside the positioning columns 14 limit the ends of the threaded rods 17. The rotation of the threaded rods 17 is controlled by the motor 16, so that the threaded rods 17 cooperate with the internal threaded tube 19 to complete the control of the position of the L-shaped pressure plate 18.

[0030] In addition, an internal threaded tube 19 is installed through the L-shaped pressure plate 18 corresponding to the position of each group of threaded rods 17. The internal threaded tube 19 is rotatably installed inside the L-shaped pressure plate 18, and the internal threaded tube 19 and the threaded rod 17 are threadedly connected. The internal threaded tube 19 rotatably installed inside the L-shaped pressure plate 18 is threadedly installed with the threaded rod 17, and due to the rotatability of the internal threaded tube 19, additional rotational force on the L-shaped pressure plate 18 is avoided when the threaded rod 17 rotates.
