Abstract
The invention discloses a mechanically sealed industrial centrifugal pump and relates to the field of protection for mechanical sealing of industrial centrifugal pumps. A circular process pipeline (3) is arranged between a pump outlet tube (2) and a pump inlet tube (4) of a centrifugal pump (1), one end of the circular process pipeline (3) is arranged behind a pump inlet valve (2), and the other end of the circular process pipeline (3) is arranged in front of a pump outlet valve (7). A regulation valve (2) is arranged on the circular process pipeline (3). The practical period of mechanical sealing of the centrifugal pump is prolonged by improving stability of inlet conditions of the centrifugal pump.
Description
Technical field:
The present invention relates to the centrifugal pump of a kind of industrial machinery sealing.
Background technique:
In commercial plant, the conveying of processing medium adopts centrifugal pump pressurized delivered mode more, and the operation period of centrifugal pump directly has influence on the stable of device.Pump shaft of centrifugal pump and and the pump housing between sealing adopt mechanical seal, mechanical seal requires higher to the working stability of centrifugal pump in running, slightly fluctuation can cause mechanical seal temperature high, and in very short time, temperature can not be fallen and mechanical seal will be caused to burn out.Centrifugal pump working stability depends on the stability of pump inlet medium, but owing to being subject to the impact of process conditions in commercial plant, the component of centrifugal pump inlet medium and pressure can change, and have a direct impact the operation stability of centrifugal pump, directly cause damage to the mechanical seal of centrifugal pump.
Summary of the invention:
The object of this invention is to provide the centrifugal pump of a kind of industrial machinery sealing, it solves the operation stability of pump by changing centrifugal pump inlet operation process condition, the operation period of prolonged mechanical sealing.
In order to solve the problem existing for background technique, it is by the following technical solutions that the present invention solves: it installs a circulation technology pipeline at outlet of centrifugal pump pipe to inlet tube, because pump discharge pressure is greater than pump inlet pressure, so medium can enter smoothly in pump inlet pipe in centrifugal pump running in outer pipe.The flow that pump discharge medium gets back to pump inlet relies on the regulating valve on circulation technology pipeline to control.Normally get 1/10 of centrifugal pump total discharge.The mounting point at circulation technology pipeline two ends must be after pump inlet valve with pump discharge valve before.
The following beneficial effect of tool of the present invention:
This practical technology, by improving the stability of centrifugal pump inlet process conditions, extends the practical cycle of mechanical face seals of centrifugal pumps.Mechanical face seals of centrifugal pumps running protection features simple and practical process.
Accompanying drawing illustrates:
Fig. 1 is process flow diagram of the present invention.
Embodiment:
With reference to figure 1, between centrifugal pump 1 pump discharge pipe 2 to pump inlet pipe 4, install circulation technology pipeline 3, mounting point, circulation technology pipeline 3 one end is after pump inlet valve 6, and the other end mounting point is before pump discharge valve 7.Circulation technology pipeline 3 is installed regulating valve 5.
Claims (2)
1. a centrifugal pump for industrial machinery sealing, is characterised in that it comprises centrifugal pump (1), pump discharge pipe (2), circulation technology pipeline (3), pump inlet pipe (4), regulating valve (5), pump inlet valve (6), pump discharge valve (7).
2. the centrifugal pump of a kind of industrial machinery sealing according to claim 1, it is characterized in that, between centrifugal pump (1) pump discharge pipe (2) to pump inlet pipe (4), circulation technology pipeline (3) is installed, circulation technology pipeline (3) mounting point, one end is after pump inlet valve (2), and the other end mounting point is before pump discharge valve (7); Circulation technology pipeline (3) is installed regulating valve (2).
