Abstract
A kind of industrial centrifugal pump mechanical sealing running protection technique; it relates to centrifugal pump resist technology field; it installs circulation technology pipeline (3) between centrifugal pump (1) pump discharge pipe (2) to pump inlet pipe (4); circulation technology pipeline (3) one end installation site is after pump inlet valve (2); other end installation site, before pump discharge valve (7), circulation technology pipeline (3) is installed control valve (2).The present invention, by improving the stability of centrifugal pump inlet condition, extends the practical cycle of mechanical face seals of centrifugal pumps.
Description
Technical field
The present invention relates to centrifugal pump resist technology field, be specifically related to a kind of industrial centrifugal pump mechanical sealing running protection work
Skill.
Background technology
Using centrifugal pump pressurized delivered mode in commercial plant the conveying of processing medium, the cycle of operation of centrifugal pump is straight more
Connect and have influence on the stable of device.Pump shaft of centrifugal pump and and the pump housing between sealing use mechanical seal, mechanical seal fortune
During row, the job stability to centrifugal pump requires higher, and slightly fluctuation can cause mechanical seal temperature high, in very short time
Temperature fall is not gone down will result in mechanical seal and is burnt out.Centrifugal pump job stability depends on the stability of pump inlet medium, but
Owing to being affected by process conditions in commercial plant, the component of centrifugal pump inlet medium and pressure can change, to from
The operation stability of heart pump has a direct impact, and directly the mechanical seal to centrifugal pump causes damage.
Summary of the invention
It is an object of the invention to provide a kind of industrial centrifugal pump mechanical sealing running protection technique, it is by changing centrifugal pump
Import operation process condition solves the operation stability of pump, the cycle of operation that prolonged mechanical seals.
In order to solve the problem existing for background technology, the present invention is by the following technical solutions: it is at outlet of centrifugal pump
A circulation technology pipeline installed by pipe to inlet tube, because pump discharge pressure is more than pump inlet pressure, so in outlet medium from
Can enter smoothly in pump inlet pipe during heart pump operation.Pump discharge medium returns to the flow of pump inlet and relies on circulation technology pipe
Control valve on line controls, and normally takes the 1/10 of centrifugal pump total flow.The installation site at circulation technology pipeline two ends must be
After pump inlet valve with pump discharge valve before.
The method have the advantages that
1, the present invention is by improving the stability of centrifugal pump inlet process conditions, extends the practical week of mechanical face seals of centrifugal pumps
Phase；
2, mechanical face seals of centrifugal pumps running protection features simple and practical process.
Accompanying drawing explanation
Fig. 1 is present invention process flow chart.
Detailed description of the invention
With reference to Fig. 1, circulation technology pipeline 3, circulation technology pipe are installed between centrifugal pump 1 pump discharge pipe 2 to pump inlet pipe 4
Line 3 one end installation site after pump inlet valve 6, other end installation site before pump discharge valve 7, circulation technology
Control valve 5 is installed on pipeline 3.Because pump discharge pressure is more than pump inlet pressure, so medium runs at centrifugal pump in outlet
During can enter smoothly in pump inlet pipe.
