Abstract
The utility model relates to a hollow spindle used as a heat flow passage in a mechanic equipment and is technically characterized in that the hollow spindle inside is provided with a sleeve; the hollow spindle is connected with the sleeve at two sides; a gas is arranged between the walls of the hollow spindle and the sleeve. The technology of the utility model reduces the direct contact area between the steam and the condensed liquid and the hollow spindle, thereby having the advantages of a reduced heat loss, a lower temperature on the hollow spindle surface and a prolonged service life of various components on the hollow spindle as well as the lubricating medium.
Description
Affiliated technical field
The utility model relate to a kind of on machinery the hollow shaft as heat passage, belong to mechanical part.
Technical background
In the existing machinery equipment as the hollow shaft of heat passage, as make the hollow shaft of steam, condensed fluid access way, because of axle can be heated by the high temperature logistics, and surface temperature is very high, the shortcoming that this structure produces is: 1, dispel the heat towards periphery in the axle surface, cause unnecessary thermal loss, particularly long axle, the serious waste energy.2, the lubricant medium of component on the axle such as bearing, gear, Sealing and use thereof etc. is in and works under the condition of high temperature, the reduction in working life.3, the service behaviour of lubricant oil or lubricating grease descends under the condition of high temperature, and the normal operation that influence axle and axle are gone up each component.
Summary of the invention
The purpose of this utility model provides the heat insulation hollow shaft of a kind of energy, and it can reduce the thermal loss on hollow shaft surface, improves lubrication effect, prolongs the working life that axle and axle are gone up each parts.
The technical solution of the utility model is: a kind of Adiabatic axle, have hollow shaft, and it is characterized in that: sleeve pipe is housed in the hollow shaft, and its two end part of hollow shaft and sleeve pipe are connected, and are gapped between the tube wall.The two end part Placement of hollow shaft and sleeve pipe can be welding, is vacuum state in the cavity, also can connect by link.
Owing to leave the gap between hollow shaft and sleeve pipe, only in the contact of joint, end, steam and condensed fluid pass through in sleeve pipe two pipes, have significantly reduced with the direct contact surface of hollow shaft long-pendingly, and the hollow shaft surface no longer is direct heat dispersing surface, so reduced thermal loss.Because the hollow shaft surface temperature is low, so prolonged the operating life of last each parts of axle and lubricant medium.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing is the structural representation of the utility model Adiabatic axle.
Specific embodiment
The outer tube of Adiabatic axle is hollow shaft (1) among the figure, and sleeve pipe (2) is housed in hollow shaft (1), and hollow shaft (1) is connected at two end part with sleeve pipe (2), gapped between tube wall (3), the end Placement can be welding, and the gap between pipe (3) are vacuum state, also can be that lap joint flange connects.
Claims (1)
1, a kind of Adiabatic axle has hollow shaft, it is characterized in that: sleeve pipe is housed in the hollow shaft, and its two end part of hollow shaft and sleeve pipe are connected, and are gapped between the tube wall.
