Abstract
The utility model provides a mechanical seal cooling and flushing device for a single-stage centrifugal pump. A cooling fluid supply tube is externally connected with a mechanical seal cavity and a static ring back cavity in the centrifugal pump, and a cooling fluid is used for cooling and flushing, so that the centrifugal pump is led to be suitable for the transportation of various mediums and especially on the occasions that solid particles are contained in the mediums or the self temperatures of the mediums are higher. The service life of the centrifugal pump can be prolonged, and the failure rate of the centrifugal pump is reduced.
Description
Technical field
The utility model 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, this is that the physics of clear water or liquid or chemical property allow 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, shorten the life-span of mechanical seal greatly, 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 in the utility model provides a kind of one-stage centrifugal pump mechanical sealing cooling and Rinsing unit, can partly provide good cooling and flushing 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 utility model 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 by the cooling cleaning hose, 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.
Cooling of one-stage centrifugal pump mechanical sealing and Rinsing unit that the utility model provides; by at the external cooling fluid supply pipe in mechanical seal chamber and chamber, the stationary ring back side; quoting cooling liquid cools off and washes; allow centrifugal pump can adapt to the conveying of multiple medium; particularly contain solid particle or medium self temperature in the medium when higher; prolong the working life of centrifugal pump, reduced the rate of fault of centrifugal pump.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the utility model structural representation.
Embodiment
In Fig. 1, a kind of one-stage centrifugal pump mechanical sealing cooling and Rinsing unit, comprise centrifugal pump 11, the high voltage terminal 4 of centrifugal pump 11 is communicated with mechanical seal chamber 3 by cooling cleaning hose 5, cooling cleaning hose 5 is provided with gate valve 6, end near mechanical seal chamber 3 on the cooling cleaning hose 5 also is provided with mechanical seal chamber external tapping 7, and chamber, the stationary ring back side 10 is communicated with chamber, stationary ring back side externally connected pipe 9.
On the described mechanical seal chamber external tapping 7 plug 8 is installed.Described mechanical seal chamber external tapping 7 is communicated with external cooling fluid supply pipe 16.Chamber, described stationary ring back side externally connected pipe 9 is communicated with external cooling fluid supply pipe 16.
Centrifugal pump 11 is connected with power source starts working, when fed sheet of a media cleaning and temperature are low, medium enters centrifugal pump 11 from suction port 1, apply kinetic energy and pressure energy and arrive high voltage terminal 4 to medium through impeller 2 rotations, to reach the lift that needs, the cooling cleaning hose 5 that connects from high voltage terminal 4 is incorporated into mechanical seal chamber 3 with medium, the gate valve 6 that cool off above the cleaning hose 5 this moment is in open mode, on the mechanical seal chamber external tapping 7 plug 8 being installed, is axle sleeve 12 so that medium arrives 3 inside, mechanical seal chamber, mechanical sealing linkage ring 13, flushing such as stationary ring 14 parts such as grade and cooling.When containing solid particle or medium self temperature in the fed sheet of a media when higher; gate valve 6 above the cooling cleaning hose 5 is in closed condition; external tapping 7 upper plug heads 8 in mechanical seal chamber take off and external cooling fluid supply pipe 16; with external cooling liquid is the inside cooling and the flushing in mechanical seal chamber 3, avoids the component in the media damage mechanical seal chamber 3.
Chamber, the stationary ring back side 10 is to form enclosed cavity by axle sleeve 12, uneven gland 15 and stationary ring 14.When the temperature of centrifugal pump 11 surpassed 60 ℃, chamber, stationary ring back side externally connected pipe 9 was connected with external cooling fluid supply pipe 16, and the introducing cooling liquid is cooled off stationary ring 14 back sides and washed.
