Abstract
A centrifugal pump for industrial machinery sealing, it relates to a kind of field to industrial centrifugal pump mechanical sealing running protection.It installs circulation technology pipeline between centrifugal pump pump discharge pipe to pump inlet pipe, and mounting point, circulation technology pipeline one end is after pump inlet valve, and the other end mounting point, before pump discharge valve, regulating valve is installed by circulation technology pipeline.It, by improving the stability of centrifugal pump inlet condition, extends the practical cycle of mechanical face seals of centrifugal pumps.
Description
Technical field
The utility model relates to the technical field to industrial centrifugal pump mechanical sealing running protection, is specifically related 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.
Model utility content
The purpose of this utility model is to provide the centrifugal pump of a kind of industrial machinery sealing, and 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 utility model solves: it comprises centrifugal pump, pump discharge pipe, circulation technology pipeline, pump inlet pipe, regulating valve, pump inlet valve, pump discharge valve, the pump discharge pipe of centrifugal pump installs circulation technology pipeline between pump inlet pipe, mounting point, circulation technology pipeline one end is after pump inlet valve, the other end mounting point, before pump discharge valve, regulating valve is installed by circulation technology pipeline.
Working principle of the present utility model: 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 the utility model tool:
This practical technology, by improving the stability of centrifugal pump inlet process conditions, extends the practical cycle of mechanical face seals of centrifugal pumps.
Accompanying drawing illustrates:
Fig. 1 is process flow diagram of the present utility model.
