Abstract
The invention discloses a single-stage centrifugal pump mechanical seal cooling and flushing device. A cooling fluid supply pipe is connected outside of a mechanical sealing chamber and a static ring back chamber in the centrifugal pump for using cooling fluid for cooling and flushing, thus causing that the centrifugal pump can be suitable for the transportation of various media, in particular, the media contains solid particles or the self temperature thereof is higher, prolonging the service life of the centrifugal pump and reducing the failure rate of the centrifugal pump.
Description
Technical field
The present invention relates to a kind of centrifugal pump cooling and Rinsing unit, particularly a kind of one-stage centrifugal pump mechanical sealing cooling and Rinsing unit.
Background technique
The axle envelope of pump industry centrifugal pump mainly adopts two kinds of sealing means at present: the one, and packing seal, the 2nd, mechanical seal.Along with the raising of environmental requirement and the particularity of institute's fed sheet of a media; The axle envelope more and more generally adopts mechanical seal; Generally speaking, cooling that mechanical seal is adopted and washing solution all are the media that pump itself is carried, and this is that physics or the chemical property of clear water or liquid allows when being similar to clear water at medium; But when containing solid particle in the liquid; This mode will cause wearing and tearing to mechanical seal, shortens the life-span of mechanical seal greatly, and it is necessary introducing clean external cooling liquid in this case; Work as the medium temperature of being carried simultaneously when too high, it also is disadvantageous to the cooling of mechanical seal, also should introduce suitable low temperature liquid and cool off.
Summary of the invention
Technical problem to be solved by this invention provides a kind of one-stage centrifugal pump mechanical sealing cooling and Rinsing unit, can good cooling and flushing partly be provided to mechanical seal, to adapt to the conveying of multiple medium.
For solving the problems of the technologies described above; The technological scheme that the present invention adopted is: a kind of one-stage centrifugal pump mechanical sealing cooling and Rinsing unit; Comprise centrifugal pump, the high voltage terminal of centrifugal pump is communicated with the mechanical seal chamber through the cooling cleaning hose, and the cooling cleaning hose is provided with gate valve; End near the mechanical seal chamber on the cooling cleaning hose also is provided with mechanical seal chamber external tapping, and chamber, the stationary ring back side is communicated with chamber, stationary ring back side externally connected pipe.
On the external tapping of described mechanical seal chamber plug is installed.
Described mechanical seal chamber external tapping is communicated with external cooling fluid supply pipe.
Chamber, described stationary ring back side externally connected pipe is communicated with external cooling fluid supply pipe.
One-stage centrifugal pump mechanical sealing cooling provided by the invention and Rinsing unit; Through external cooling fluid supply pipe in mechanical seal chamber and chamber, the stationary ring back side; Quote cooling liquid and cool off and wash, when centrifugal pump can be adapted to contain in the conveying, particularly medium of multiple medium solid particle or medium self temperature higher; Prolong the working life of centrifugal pump, reduced the rate of fault of centrifugal pump.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is described further.
Fig. 1 is a structural representation of the present invention.
