Abstract
A fixing base for an ultralow-temperature device comprises two bottom supporting frames used for supporting the device. Each bottom supporting frame is provided with a base. A steel spacer is welded to the position above each base and is used for being polished for leveling when the device is installed. A PTFE spacer is arranged on the steel spacer of the base at one end, and the end serves as the movable end. The ultralow-temperature device is arranged on the fixing base, and the requirement for the flatness of the ultralow-temperature device can be met by polishing the steel spacers; as the PTFE spacer is arranged at the movable end of the base, the friction coefficient between the ultralow-temperature device and the base can be reduced, the deformation amount produced by heat-expansion and cold-contraction of the ultralow-temperature device can be effectively released, and the service life of the ultralow-temperature device is prolonged.
Description
Technical field
The present invention relates to ship ' s equipment design, particularly a kind of firm banking for ultralow temperature equipment.
Background technology
Seat of honour floating LNG device in the world, liquefying plant and the module that gasifies are again transferred on boats and ships by land first.Liquefying plant and the module that gasifies are again arranged in main deck, and liquefying plant can receive high-pressure natural gas on the bank by marineline, and re-vaporization module can guarantee that barge is not when receiving on the bank natural fuels, and barge can be used as an input terminal.
The tank body equipment feature of liquefying plant and the module that gasifies again:
1. tank body difference variation large (as example mesohigh separator device, working temperature range is at-10 ℃ to 65 ℃);
2. tank body is larger, long. and (as example mesohigh separator device, 1 meter of internal diameter, long 3.7 meters);
Thereby equipment tank body can be larger owing to expanding with heat and contract with cold the deflection producing; add the distortion of hull structure itself so distortion is obvious on the impact of equipment; so how to allow equipment better discharge because of produced deflection and the shipbody deformation of expanding with heat and contract with cold, protection service life of equipment and safety are very crucial things.
Summary of the invention
In order to overcome the defect of above-mentioned prior art, the object of the present invention is to provide a kind of firm banking for ultralow temperature equipment, friction coefficient is low, and equipment can guarantee service life and safety in upper movement.
In order to achieve the above object, technical scheme of the present invention is:
For a firm banking for ultralow temperature equipment, comprise two bottom support framves 1 of fastening, on each bottom support frame, be provided with pedestal 2, pedestal 2 tops are welded with steel plate washer 3; The pad 3 of one end pedestal 2 is also provided with the pad 4 of one deck polytetrafluoroethylene PTFE above therein.
The added pad 4 of the present invention is polytetrafluoroethylene (PTFE), is claimed " King ", Chinese trade name " teflon ".There is good chemical inertness, corrosion stability, there are leak tightness, high lubricated not viscosity, electrical insulating property and good aging resistance, heatproof excellent (can long-term work at the temperature of-180 ℃ to 250 ℃) and have good mechanical characteristics, pressure 10Mpa between-100 ℃ to 100 ℃.Friction coefficient is extremely low.When therefore equipment moves, can better discharge because of produced deflection and the shipbody deformation of expanding with heat and contract with cold protection service life of equipment and safety in the above.
Accompanying drawing explanation
Accompanying drawing is structural representation of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing, structural principle of the present invention and principle of work are described in detail.
With reference to accompanying drawing, a kind of firm banking for ultralow temperature equipment, comprises and two bottom support framves 1 of fastening is provided with pedestal 2 on each bottom support frame, pedestal 2 tops are welded with steel plate washer 3, for polish leveling when erecting equipment; The pad 3 of one end pedestal 2 is also provided with the pad 4 of one deck polytetrafluoroethylene PTFE above therein, and this end is as movable end.
Principle of work of the present invention is: equipment is placed on the present invention, in the time of installation, can reach the requirement of equipment planeness by polishing steel plate washer 3, by polytetrafluoroethylene (PTFE) pad is set at base movable end, can reduces friction coefficient between equipment and base and then can actv. help the deflection extension device service life of releasing arrangement because expanding with heat and contract with cold produced.
