Abstract

The invention discloses a centrifugal pump with an industrial mechanical seal, and relates to the field of industrial centrifugal pump mechanical seal running protection. A circulation process pipeline is installed between a pump outlet pipe of the centrifugal pump and a pump inlet pipe of the centrifugal pump, the installation position of one end of the circulation process pipeline is located behind a pump inlet valve, the installation position of the other end of the circulation process pipeline is located in front of a pump outlet valve, and an adjusting valve is installed on the circulation process pipeline. By means of the centrifugal pump, the practical period of the mechanical seal of the centrifugal pump is prolonged by improving the stability of the inlet condition of the centrifugal pump.

Description

The centrifugal pump that a kind of industrial machinery seals
Technical field
The present invention relates to the technical field to industrial centrifugal pump mechanical sealing running protection, be specifically related to the centrifugal pump that a kind of industrial machinery seals.
Background technology
Adopting centrifugal pump pressurized delivered mode in commercial plant the conveying of processing medium, the cycle of operation of centrifugal pump directly influences the stable of device more.Pump shaft of centrifugal pump and and the pump housing between sealing adopt mechanical seal, the job stability of centrifugal pump is required higher by mechanical seal in running, slightly fluctuation can cause mechanical seal temperature high, and in very short time, temperature can drop and will result in mechanical seal and burn out.Centrifugal pump job 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 the operation stability of centrifugal pump is had a direct impact, and directly the mechanical seal of centrifugal pump caused damage.
Summary of the invention
It is an object of the invention to provide the centrifugal pump that a kind of industrial machinery seals, it solves the operation stability of pump, the cycle of operation that prolonged mechanical seals by changing centrifugal pump inlet operation process condition.
In order to solve the problem existing for background technology, this invention address that it is by the following technical solutions: it comprises centrifugal pump, pump discharge pipe, circulation technology pipeline, pump inlet pipe, control valve, pump inlet valve, pump discharge valve, the pump discharge pipe of centrifugal pump installs circulation technology pipeline between pump inlet pipe, circulation technology pipeline one end installation site is after pump inlet valve, other end installation site, before pump discharge valve, circulation technology pipeline is installed control valve.
The operation principle of the present invention: it installs a circulation technology pipeline at outlet of centrifugal pump pipe to inlet tube, because pump discharge pressure is more than pump inlet pressure, so medium can enter smoothly in pump inlet pipe in centrifugal pump running in outlet, pump discharge medium returns to the flow of pump inlet and relies on the control valve on circulation technology pipeline to control, normally take 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 present invention has following beneficial effect:
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 the process flow diagram of the present invention.
Detailed description of the invention
With reference to Fig. 1, the centrifugal pump that a kind of industrial machinery seals, it comprises centrifugal pump 1, pump discharge pipe 2, circulation technology pipeline 3, pump inlet pipe 4, control valve 5, pump inlet valve 6, pump discharge valve 7, circulation technology pipeline 3 is installed 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 6, and other end installation site is before pump discharge valve 7.Circulation technology pipeline 3 is installed control valve 5.
