Description

Technical Field

[0001] This utility model relates to the field of vertical pump technology, and in particular to an ultra-long shaft vertical pump suitable for conveying clean media / media containing small-sized impurities in industries and fields such as offshore platform oil / LNG extraction, onshore LNG / oil extraction, refineries, petrochemicals, cryogenic applications, and marine industries, with a minimum insertion depth. Background Technology

[0002] Currently, in offshore platform mining projects, due to the fluctuations of the sea surface, the equipment is constantly in a state of tilting and swaying during operation. This causes the gap between the rotating and stationary parts of the pump unit to change with the tilting and swaying. In severe cases, this can lead to friction or even seizing between the rotating and stationary parts, resulting in a reduction in the service life of the pump unit or damage.

[0003] In view of the problems existing in the above-mentioned existing technologies, it is necessary to research and design a new type of ultra-long shaft vertical pump to overcome the problems existing in the existing technologies. Summary of the Invention

[0004] To address the technical problems raised by the prior art, such as the equipment being constantly tilted and swaying due to sea surface fluctuations, resulting in friction or even seizing between the rotating and stationary parts of the pump unit, which reduces the service life of the pump unit or causes damage, an ultra-long shaft vertical pump is provided.

[0005] The technical means adopted in this utility model are as follows:

[0006] An ultra-long shaft vertical pump includes: a motor frame, an outlet section, a support piping system, and hydraulic components; the motor frame is installed on the upper part of the outlet section, and the lower end of the outlet section is connected to the support piping system; the hydraulic components are installed at the lower end of the support piping system, and different hydraulic components can be changed to achieve different hydraulic performance.

[0007] Furthermore, bearing components are mounted on the motor bracket;

[0008] Furthermore, the support piping system consists of multi-section connectors. By changing the number of sections in the support piping system, the length of the support piping system can be varied, thus achieving ultra-long shaft vertical pump structures of different lengths.

[0009] Furthermore, a support structure is provided on the support piping system.

[0010] Furthermore, the support structure is configured with different numbers of supports based on the pump's length and inherent frequency analysis, achieving multi-point elastic support; this increases the rigidity of the pump unit structure, reduces the swaying of the lower end of the pump, lowers the vibration of the pump unit, and ensures the reliable operation of the pump.

[0011] Furthermore, the supporting structure is installed between the supporting piping system and the cylinder wall;

[0012] Furthermore, one end of the support structure is connected to the support piping system by welding or fasteners, while the other end is tightly against the cylinder wall through anti-sway springs and anti-sway arms, thus providing support for the pump.

[0013] Furthermore, the support structure employs three sets of support structures at the same height as the support piping system, which can prevent the pump from being over-positioned and better ensure the pump's operating condition when it tilts or sways in any direction, thereby increasing the pump's service life.

[0014] Furthermore, the support structure includes: an upper support rod and a lower support rod;

[0015] Furthermore, the upper support rod and the lower support rod are set horizontally;

[0016] Furthermore, one end of the upper support rod and the lower support rod are connected to the support pipe system by welding or fastening.

[0017] Furthermore, the upper support rod is connected to the anti-sway spring via fasteners;

[0018] Furthermore, the anti-sway spring is connected to the anti-sway arm, which in turn connects the support rod to the anti-sway arm;

[0019] Furthermore, by controlling the distance between the support rod and the anti-rocker arm, the compression range of the spring is adjusted, thereby controlling the elongation and supporting force of the anti-rocker arm to support the pump.

[0020] Furthermore, the lower support rod is hinged to the end of the anti-rocker arm furthest from the anti-rocker spring via an adjusting rod;

[0021] Furthermore, the anti-rocker arm automatically rotates around the adjusting rod according to the compression / extension length of the anti-rocker spring, changing its relative position with the lower support rod, thereby providing support for the pump to tilt and sway to different degrees.

[0022] Compared with the prior art, the present invention has the following advantages:

[0023] 1. The ultra-long shaft vertical pump provided by this utility model has a simple, stable, and sufficiently strong design structure, and can achieve safe and stable operation of the pump under inclined and swaying conditions;

[0024] 2. The ultra-long shaft vertical pump provided by this utility model adopts a multi-point elastic support structure, which enhances the rigidity of the pump set and improves the reliability of pump operation.

[0025] 3. The ultra-long shaft vertical pump provided by this utility model has a support structure installed between the pump and the cylinder wall. By compressing the anti-sway spring, the anti-sway arm is kept close to the cylinder wall, which provides support for the pump.

[0026] 4. The ultra-long shaft vertical pump provided by this utility model adopts three sets of support structures at the same height of the support pipe system, which can avoid the pump being over-positioned, ensure the pump's good operating condition when tilted or swaying in any direction, and improve the pump's service life.

[0027] 5. The ultra-long shaft vertical pump provided by this utility model compensates for the offset caused by tilting and swaying with anti-sway springs, so that the support structure always provides support force, ensuring the smooth operation of the pump;

[0028] 6. The ultra-long shaft vertical pump provided by this utility model has an anti-shake arm that can automatically rotate according to the change of the anti-shake spring, ensuring the support function against different degrees of tilting and swaying.

[0029] In summary, the technical solution of this utility model solves the problems in the prior art where the equipment is always in a state of tilting and swaying due to sea surface fluctuations, which causes friction or even seizing between the rotating and stationary parts of the pump unit, reducing the service life of the pump unit or causing damage.
