Abstract
The invention discloses a sealing cooling structure of a rotating device. The sealing cooling structure of the rotating device comprises a mechanical sealing cavity and a sealing liquid pot, and is characterized in that the mechanical sealing cavity is connected with the sealing liquid pot through a connecting pipe, and a cooling mechanism is arranged inside the mechanical sealing cavity. According to the sealing cooling structure of the rotating device, due to the fact that the cooling mechanism is arranged inside the mechanical sealing cavity, the heat exchanging effect of the mechanical sealing cavity is improved, and use reliability of the device is improved.
Description
Technical field
The present invention relates to a kind of sealing cooling structure, be specifically related to a kind of sealing cooling structure of rotating machinery.
Background technique
Mechanical seal (mechanical seal) refers to kept under the effect of hydrodynamic pressure and compensation mechanism elastic force (or magnetic force) and under the cooperation of auxiliary seal fitting and relative slip the and the device that prevents the fluid leakage that constitutes perpendicular to the end face of spin axis by at least one pair of.Mechanical seal is a kind of oil-sealing arrangement of rotating machinery, such as equipment such as centrifugal pump, centrifuge, stirred tank and compressors.In industrial production, stirred tank is a kind of container or device that has agitating function, can be used to carry out the mixing of material or separation etc., also can be used for carrying out some chemical reaction, is a kind of manufacturing mechanism commonly used.
In actual use, for the equipment that similarly slowly runs such as stirred tank or pump, its mechanical seal chamber 1 connects the sealing liquid jar 4 with cooling coil 3 by two stainless steel connecting tubes 2 and carries out the sealing fluid cycle heat exchange, specifically referring to shown in Figure 1, because it is low that installing is equipped with speed own, the equipment beat is big again, and conventional pumping ring can not play the effect that drives the sealing fluid circulation.Thereby the principle that all adopts thermal siphon in arranging in the industry at present basically realizes the heat exchange of Seal cage and sealing liquid jar, but using the scene, owing to exhaust, sealing liquid viscosity, pipe layout and other pipe resistance bigger etc. reason, pipeline circulates frequent foundation not, the Seal cage heat can't be pulled away, cause the mechanical seal overheating failure or do not reach the desired life of expection, thereby influenced the operational safety of equipment.
Summary of the invention
The object of the invention provides a kind of sealing cooling structure of rotating machinery, by the improvement to structure, has improved the heat exchange effect in mechanical seal chamber, has improved the operational safety of equipment.
Technological scheme of the present invention is: a kind of sealing cooling structure of rotating machinery, comprise a mechanical seal chamber and sealing liquid jar, described mechanical seal is provided with liquid container in the chamber, is connected through a connecting tube between described mechanical seal chamber and described sealing liquid jar, and described mechanical seal is provided with cooling mechanism in the chamber.
Further technological scheme, described cooling structure comprises the cooling coil that is arranged in the described liquid container, and described cooling coil two ends are respectively equipped with cooling water intake and coolant outlet, and described cooling water intake and coolant outlet place are provided with control valve respectively.
Be connected through a connecting tube between further technological scheme, described liquid container and described sealing liquid jar.
Further technological scheme, described connecting tube is Stainless Steel Tube.
In the above technological scheme, described rotating machinery is stirred tank.
Advantage of the present invention is:
1. the present invention is by arranging cooling coil in the mechanical seal chamber, directly in the mechanical seal chamber, carry out cycle heat exchange, and have only a connecting tube to be connected with the sealing liquid jar, need not as compared with the past to consider whether the sealing fluid circulation between mechanical seal chamber and sealing liquid jar is effective, whether pipe-line layout or resistance loss of pipeline be reasonable, thereby improved the operational safety of equipment greatly;
2. the present invention need not existing structure is changed on a large scale, is easy to realize, is fit to promote the use of.
