On cooler cooling fin 15 on week, by the efficiently heat dissipation outward of cooler cooling fin 15, therefore, high-temp liquid medium is being confused
Temperature is gradually decreased in flow process in palace channel 10, until the temperature of high-temp liquid medium has cooled down when cooler outlet 11
It is required to the cooling for close to room temperature, being fully able to meet mechanical seal;
3) liquid medium flowed out from cooler outlet 11 introduces mechanical seal cooling liquid inlet by cooling water pipe 13
18, it enters in mechanical seal cooling chamber 19, cooling is carried out to mechanical seal 17 close to room temperature medium with this, is lubricated, to protect
The working environment for having demonstrate,proved mechanical seal 17 works with enabling the safe and reliable long-life of mechanical seal 17, cooling in mechanical seal
Setting throttling passage 20 in the outlet of room 19 plays throttling action to the liquid medium for flowing into mechanical seal cooling chamber 19, guarantees mechanical close
Pressure required for 17 cooling and lubricatings is sealed, mechanical seal cooling chamber 19, section are passed through to the medium after 17 cooling and lubricating of mechanical seal
Circulation road 20, impeller return port 21 flow back into 22 import of impeller, are pumped again by impeller 22, the process for repeating step 1);So far,
It completes to draw high-temp liquid medium from the pumped (conveying) medium outlet 2 on hot water pump discharge 1, it is cold through labyrinth channel 10, cooling fin 15
But after, cooling and lubricating is carried out to mechanical seal 17, finally returns 22 import of impeller from cooling cycle, entire circulation envelope completely
It closes, to the external world without any pollution, and energy conservation and environmental protection is applicable to the working environment of a variety of heat-exchanger pumps without external cooling water.
