Abstract
The utility model discloses a cooling structure of a mechanical seal. The cooling structure comprises a cooling coil and a tube connector, the cooling coil is installed between the mechanical seal and a sealing cavity, and the tube connector penetrates through the sealing cavity to be communicated with the cooling coil. The cooling structure has the advantages of being simple in structure, capable of freely assembling and disassembling, convenient to maintain and capable of effectively reducing the temperature of the sealing cavity, enabling the mechanical seal to work under a low temperature environment, and guaranteeing normal running of the mechanical seal.
Description
Technical field
The utility model relates to the mechanical seal field, is specifically related to a kind of cooling structure of mechanical seal.
Background technique
Mechanical seal sealing surface in operation process can produce certain frictional heat; The rotary component agitated liquid also can produce heat, if can not in time heat be distributed, thermal accumlation is to a certain degree making sealing surface produce thermal distortion; Thereby cause seal leakage, so need seal chamber be cooled.
The model utility content
The purpose of the utility model is to overcome above-mentioned not enough problem, and a kind of cooling structure of mechanical seal is provided.
The utility model for realizing the technological scheme that above-mentioned purpose adopted is: a kind of cooling structure of mechanical seal; Comprise cooling coil, pipe joint; Said cooling coil is installed between mechanical seal and the seal chamber, and said pipe joint passes seal chamber and is connected with said cooling coil.
In the said pipe joint spacer ring is installed, and said spacer ring two ends are separately installed with O type circle.
Said pipe joint is connected with said seal chamber through its outside thread.
The external diameter of said cooling coil is less than the internal diameter 1-2mm of seal chamber, and the internal diameter of said cooling coil is greater than the external diameter 5-6mm of mechanical seal.
The two ends of said cooling coil are separately installed with a pipe joint.
The characteristics of the utility model are: simple in structure, can freely load and unload, and be convenient to maintenance, can effectively reduce the temperature of seal chamber, mechanical seal is worked under lower temperature environment, guarantee that mechanical seal runs well.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Wherein: 1, mechanical seal 2, seal chamber 3, cooling coil 4, O type circle 5, spacer ring 6, O type circle 7, pipe joint.
Embodiment
As shown in Figure 1, the present invention includes cooling coil 3, pipe joint 7, said cooling coil 3 is installed between mechanical seal 1 and the seal chamber 2; The two ends of said cooling coil 3 are separately installed with a pipe joint 7, and said pipe joint 7 is by the stainless steel manufacturing, and said pipe joint 7 passes seal chamber 2 and is connected with said cooling coil 3; Said pipe joint 7 is connected with seal chamber 2 through its outside thread, and the internal thread of said pipe joint 7 is connected with the on-the-spot adapter of user, in the said pipe joint 7 spacer ring 5 is installed; Said spacer ring 5 is by the polytetrafluoroethylmaterial material manufacturing, and said spacer ring two ends are separately installed with O type circle 4,6, not leakage between assurance cooling coil 3 and the pipe joint 7; And described pipe joint 7, spacer ring 5, and O type circle 4,6; Can freely dismantle, be convenient to maintenance, said cooling coil 3 is by Stainless Steel Tube dish system; The external diameter of said cooling coil is less than the internal diameter 1-2mm of seal chamber 2; So that said cooling coil 3 can be packed into smoothly in the seal chamber 2, the internal diameter of said cooling coil 3 be greater than the external diameter 5 of mechanical seal 1 ~-6mm, to prevent the swivel assembly scratching of said cooling coil 3 and sealing; When mechanical seal 1 work, through interface logical cooling water in cooling coil 3 of pipe joint 7, thereby reduce the temperature in the seal chamber 2, mechanical seal 1 is worked under lower temperature environment, guarantee the normal operation of mechanical seal 1.
The above; Be merely the preferable embodiment of the utility model; But the protection domain of the utility model is not limited thereto; Any technician who is familiar with the present technique field is equal to replacement or changes according to the technological scheme of the utility model and model utility design thereof in the technical scope that the utility model discloses, and all should be encompassed within the protection domain of the utility model.
