Abstract
The utility model discloses an anti-overheating pump, comprising a pump (1). The anti-overheating pump is characterized in that a heat exchanger (2) is connected between an outlet pipeline (3) of the pump and a mechanical seal gland of the pump. The anti-overheating pump disclosed by the utility model has the advantages of being simple in structure, convenient in installation and operation, and capable of preventing the overheating of the pump body of the pump and the easy leakage of the mechanical seal of the pump, etc; and the anti-overheating pump is suitable for pumping out materials on the bottom of a high-temperature tower.
Description
Technical field
The utility model relates to a kind of anti-overheated pump, particularly a kind of pump that is used for the extraction of high temperature bottoms material.
Background technique
At chemical field, a lot of industrial production devices all relate to the extraction of high temperature bottoms material, and this just need use resistant to elevated temperatures pump.The restriction pump at high temperature subject matter of operation steady in a long-term is revealed exactly, and reveals main inefficacy from mechanical seal, finds through the reality maintenance; The main parts of mechanical seal inefficacy are exactly the seal ring of motor-driven stationary ring; If the seal ring non-refractory of mechanical seal, too high when the Seal cage temperature, seal ring of moving ring will thermal softening; With axle sleeve together; Cause rotating ring free floating vertically, with the wearing and tearing or the displacement of compensation rotating ring, this is the main cause of a large amount of leakages of axle envelope so that splash.Existing pump major part all is to adopt the material that pump is exported to draw one to send into the pump Seal cage; This part material plays effect lubricated, that wash, lower the temperature to mechanical seal; If but under the transported material temperature condition with higher of pump, can cause the temperature of mechanical seal too high, seal ring will thermal softening; Also accelerate simultaneously the aging of seal ring, thereby caused the leakage of material.
Summary of the invention
The utility model solves can above problem, and a kind of structure, simple to operate is provided, and is suitable for the pump of high temperature bottoms material extraction.
In order to solve above-mentioned technical problem, the utility model is realized through following technological scheme: a kind of anti-overheated pump, comprise pump, and it is characterized in that: connect a heat exchanger between the outlet line of said pump and the pump mechanical seal cover.
Adopt between the inlet of said heat exchanger and the pump outlet line and be welded to connect.
The outlet of said heat exchanger and the mechanical seal cover of pump adopt the kink screwed connection.
The utility model gets into the mechanical seal chamber after the pipeline that directly be connected the mechanical seal chamber is originally cooled off material through a heat exchanger again; So not only material is cooled off; The material of cooling is taken away the frictional heat between the dynamic and static ring through the flushing to mechanical seal simultaneously; Thereby prevent that crossing thermal softening because of the seal ring of pump mechanical seal reveals with the aging material that causes, prolonged the working life of mechanical seal ring, have simple in structure; Installation, easy to operate is applicable to the extraction of high temperature bottoms material.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Among the figure, 1 is pump, and 2 is heat exchanger, and 3 is the pump outlet line.
Embodiment
Below in conjunction with accompanying drawing and practical implementation instance the utility model is done further to set forth.
Can know from Fig. 1; The utility model is prevented overheated pump; Comprise pump 1 and heat exchanger 2, the inlet of heat exchanger 2 is connected on the pump outlet line 3, and the outlet of heat exchanger is connected on the pump mechanical seal cover; Adopt between heat exchanger and the pump outlet line 3 to be welded to connect, the outlet of heat exchanger and the mechanical seal cover of pump adopt the kink screwed connection.
More than show and described basic principle of the utility model and the advantage of major character and the utility model; The technician of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described, under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications; These variations and improvement all fall in the utility model scope that requires protection, and the utility model requires protection domain to be defined by appending claims and equivalent thereof.
