Mounting structure of compressor unit

Abstract

This utility model discloses an installation structure for a compressor unit, relating to the field of compressor installation technology. It includes a compressor head assembly, comprising an adjusting block disposed between the motor and the compressor head skid. The adjusting block specifically includes: a base mounted on the compressor head skid; a spherical slide block, the lower part of which is connected to the base via a matching threaded structure; and a spherical slider that engages with the spherical slide block via a spherical surface. The spherical slider and spherical slide block utilize a spherical structure, allowing for free rotation in multiple directions and flexibly adapting to the fine-tuning needs of the motor's horizontal angle. Combined with the threaded connection between the spherical slide block and the base, precise vertical height adjustment can be achieved. The synergistic effect of both significantly improves the alignment accuracy of the motor and compressor axes, effectively solving the problem of inaccurate alignment with traditional shim adjustment methods, ensuring strict collinearity of the two shaft axes, and significantly reducing equipment wear caused by alignment deviations.

Description

Technical Field

[0001] This utility model relates to the field of compressor installation technology, and specifically to an installation structure for a compressor unit. Background Technology

[0002] In industrial production, compressor units, as core power equipment, directly determine their operating efficiency, service life, and safety stability through installation accuracy. The alignment of the motor and compressor axes and the effectiveness of vibration isolation are key technical indicators during installation. Currently, the traditional compressor unit installation method commonly used in the industry follows a process of "fixing the compressor first, then installing the motor," specifically as follows: First, the compressor is fixed to a predetermined position on the unit skid using a compressor bracket. Then, the motor is hoisted to the installation area. Adjusting the motor's vertical height requires adding or removing metal shims of varying thicknesses between the motor base and the skid. Operators must repeatedly move the motor, change the shim specifications, and retighten until the height approaches the preset value. Adjusting the motor's lateral and longitudinal horizontal distance relies on adjusting screws located on the edge of the base. By turning these screws one by one, the motor base is moved to align the motor and compressor axes.

[0003] The core requirement of this installation method is to ensure that the axis of the motor output shaft and the axis of the compressor input shaft are strictly collinear, and this collinearity must be kept horizontal and parallel to the edge of the unit skid. Otherwise, additional radial and axial forces will be generated during the coupling transmission process, causing abnormal vibration and increased noise of the unit. In severe cases, it may even cause bearing wear, shaft breakage and other failures.

[0004] However, traditional installation methods have many insurmountable technical drawbacks, specifically in the following aspects:

[0005] 1. Due to the limited thickness specifications of the shims (usually in increments of 0.5mm and 1mm), continuous fine-tuning of the motor height is not possible. Multiple attempts and replacements of the shims are required to approach the target height. Lateral and longitudinal distance adjustments rely on manual screw turning to drive the motor. Lacking a precise positioning reference, operators need to use tools such as dial indicators to repeatedly measure the coaxiality of the two axes. The entire adjustment process often requires 2-3 technicians to work together for several hours, which is not only time-consuming and labor-intensive, but also makes it difficult to guarantee the alignment accuracy.

[0006] 2. After the unit is pre-assembled in the factory, the relative positions of the motor and compressor are prone to shift due to bumps and vibrations during transportation, requiring re-alignment upon arrival at the site. Secondary alignment necessitates the removal of installed pipes, cables, and other auxiliary components, which not only extends the on-site installation period but also incurs additional manpower and equipment costs, significantly increasing the overall installation cost.

[0007] 3. In traditional installation methods, the motor, compressor, and unit skid are rigidly connected (or only damped by simple rubber pads). The skid typically integrates containers such as gas tanks, coolers, and filters. During operation, these containers transmit vibrations to the motor and compressor through the skid, causing dynamic misalignment of the two shafts and compromising initial alignment accuracy. Furthermore, vibration transmission accelerates wear on critical components such as motor and compressor bearings, shortening the unit's lifespan, increasing maintenance frequency and costs, and failing to meet the long-term stable operation requirements of industrial production. Utility Model Content

[0008] The purpose of this utility model is to provide an installation structure for a compressor unit to solve the problems of difficult alignment, cumbersome on-site correction, and poor vibration reduction effect in traditional installation methods, so as to achieve rapid and accurate alignment between the compressor and the motor, while isolating external vibration interference and ensuring stable operation of the unit.

[0009] To achieve the above objectives, this application proposes an installation structure for a compressor unit, comprising:

[0010] The head assembly includes a head skid, on which a motor and a compressor are mounted, and the output shaft of the motor and the input shaft of the compressor are connected by a coupling.

[0011] An adjusting block, located between the motor and the compressor head skid, is used to adjust the relative position of the motor and the compressor. The adjusting block specifically includes:

[0012] The base, mounted on the machine head skid, provides a supporting foundation;

[0013] The spherical slide block has its lower part connected to the base via a matching threaded structure. By rotating the spherical slide block, linear displacement in the vertical direction can be achieved, thereby adjusting the installation height of the motor.

[0014] The spherical slider, which engages with the spherical slide block through the spherical surface, can rotate in multiple directions around the center of the sphere, thereby adjusting the horizontal angle of the motor and ensuring that the axes of the motor and the compressor remain collinear in the horizontal direction.

[0015] In one embodiment, the nose skid is mounted on the unit skid via multiple shock-absorbing blocks.

[0016] In one embodiment, the bolt passes sequentially through the nut, the first flat washer, the motor, the spherical slider, the spherical slide block, the base, the head skid, and the second flat washer to secure the connection.

[0017] In one embodiment, an adjustment gap is provided between the inner wall of the through hole of the spherical slider and the bolt rod, providing space for the spherical slider to adjust its angle in the horizontal direction.

[0018] In one embodiment, the spherical slide block has a T-shaped structure, and its top is recessed with an arc-shaped spherical surface that matches the spherical slider.

[0019] In one embodiment, the bottom of the spherical slider is provided with an arc-shaped spherical surface that matches the arc-shaped spherical surface of the spherical slide block. Through the cooperation of the concave and convex spherical surfaces, the spherical slider can rotate within a range of multiple angles.

[0020] In one embodiment, the motor is provided with symmetrical adjustment screws on both sides of the lateral direction and symmetrical adjustment screws on both sides of the longitudinal direction, so as to assist in positioning and adjusting the motor from the lateral and longitudinal directions.

[0021] In one embodiment, the adjusting screw is mounted on the headstock skid via a support plate.

[0022] In one embodiment, the adjustment blocks are respectively arranged around the bottom of the motor in a rectangular distribution.

[0023] In one embodiment, the compressor is mounted on a compressor head skid via a compressor bracket.

[0024] The advantages of the above technical solution adopted in this utility model compared with the prior art are:

[0025] 1. The combined design of a threaded structure for height adjustment and a spherical structure for angle fine-tuning replaces the traditional, cumbersome shim addition and removal operations. Precise alignment can be achieved without repeatedly moving the motor, significantly simplifying the installation process and shortening the installation period. At the same time, this integrated adjustment structure is easy for operators to master quickly, reducing reliance on the experience level of technicians and significantly improving installation efficiency.

[0026] 2. The compressor head assembly, as an independent module, connects to the unit skid and, in conjunction with vibration damping blocks, effectively prevents vibrations from other equipment on the unit skid from being transmitted to the compressor and motor. Simultaneously, the stable relative positions of the core components ensure dynamic balance during operation, reducing component loosening and fatigue damage caused by vibration, and significantly improving the unit's operational reliability and service life.

[0036] Please see Figure 1-3 This embodiment provides an installation structure for a compressor unit, which mainly includes two parts: the compressor head assembly and the adjusting block.

[0037] The head assembly, as a core functional module, includes a head skid, on which a motor and a compressor are mounted. The output shaft of the motor and the input shaft of the compressor are connected by a coupling to form a transmission connection, constituting a complete power transmission system.

[0038] The adjusting block, located between the motor and the head skid, is a key component for achieving precise alignment. Specifically, it includes:

[0039] Base: Fixedly installed on the machine head skid, providing a stable support foundation for the entire adjustment structure;

[0040] Spherical slide: The lower part is connected to the base through a matching threaded structure. By rotating the spherical slide, linear displacement in the vertical direction can be achieved, thereby precisely adjusting the installation height of the motor.

[0041] Spherical slider: It cooperates with the spherical slide block through the spherical surface and can rotate in multiple directions around the center of the sphere, so as to realize the flexible adjustment of the horizontal angle of the motor and thus ensure that the axis of the motor and the compressor remain collinear in the horizontal direction.

[0042] As a preferred embodiment provided in this example, the turbine head skid is mounted on the unit skid by a plurality of evenly distributed shock-absorbing blocks. This design can effectively isolate vibrations generated by other equipment on the unit skid.

[0043] For connection and fixation, bolts are used to pass through the nut, the first flat washer, the motor, the spherical slider, the spherical slide block, the base, the head skid, and the second flat washer in sequence for fastening. This multi-layer fastening structure, combined with the double flat washer design, can ensure connection strength while dispersing stress to prevent component deformation.

[0044] A special adjustment gap is provided between the inner wall of the through hole of the spherical slider and the bolt rod, which provides sufficient space for the spherical slider to adjust its angle in the horizontal direction.

[0045] The spherical slide block adopts a T-shaped structure design, with a concave arc-shaped spherical surface at the top that matches the spherical slider; correspondingly, the bottom of the spherical slider has a convex arc-shaped spherical surface that matches the arc-shaped spherical surface of the spherical slide block. Through this precise fit of concave and convex spherical surfaces, the spherical slider can rotate flexibly within a multi-angle range, while ensuring support stability during the adjustment process.

[0046] To further improve adjustment accuracy, symmetrical adjustment screws are provided on both sides of the motor in the horizontal direction and on both sides in the vertical direction, allowing for auxiliary positioning and adjustment of the motor in both directions. These adjustment screws are mounted on the machine head skid via support plates to prevent deformation during adjustment.

[0047] The adjusting blocks are arranged in a rectangular pattern around the bottom of the motor. This layout ensures that the motor is subjected to uniform force and will not tilt during the adjustment process, thus ensuring a smooth and reliable centering process.

[0048] The compressor is mounted on the compressor head skid via a compressor bracket. The compressor bracket is made of high-strength steel and is rigidly connected to the compressor head skid to ensure the compressor's position is stable during operation and to provide a reliable reference for alignment.

[0049] In this embodiment, the assembly of the compressor head assembly follows the process of "first fixing the compressor, then adjusting the motor":

[0050] First, the compressor is fixedly installed in the preset position on the compressor head skid using the compressor bracket to ensure that the compressor position is stable;

[0051] At the four corners of the motor mounting area on the machine head skid, install adjusting blocks to suspend the motor on the spherical sliders of the four adjusting blocks and initially connect the coupling;

[0052] The adjustment process consists of two steps: height adjustment and horizontal adjustment.

[0053] Height adjustment: The motor height can be precisely adjusted by rotating the spherical slide block and utilizing its threaded engagement with the base;

[0054] Horizontal adjustment: Fine adjustment of the motor's horizontal angle can be achieved by using horizontal and vertical adjustment screws in conjunction with the multi-angle rotation characteristics of the spherical slider;

[0055] After alignment, the adjusting block is fastened to the motor and the head skid using bolts, nuts, the first flat washer, and the second flat washer to lock the motor position.

[0056] Finally, the assembled compressor head assembly is installed onto the unit skid using shock absorbers, completing the installation of the entire compressor unit.

[0057] The advantage of this implementation lies in the scientific design of the combined spherical and threaded adjustment structure, which ensures both the flexibility and precision of adjustment while providing sufficient structural strength and stability. The modular design of the compressor head assembly makes it suitable not only for installation in new units but also for upgrading existing equipment. It can be widely applied to compressor units of different specifications and types, exhibiting strong versatility and practicality.

[0058] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
