Description
Technical Field
The utility model relates to a centrifugal pump technical field especially relates to a centrifugal pump machine seals water cooling system for sewage plant.
Background
The construction period of a sewage plant mostly adopts a high-power centrifugal pump, the original design is provided with circulating self-cooling, the cooling pipe is easy to be polluted and blocked due to more sludge and impurities in the sewage, the temperature can be gradually increased after long-time operation, in order to reduce the aging speed of the shaft seal and prolong the service life of the shaft seal, the temperature of the shaft seal must not exceed a certain value, therefore, measures must be taken to take away the heat generated by the shaft seal in time so as to maintain the temperature of the pump body not to exceed the specified value, the original mechanical seal is designed to prevent the sewage liquid in the pump shell from leaking out along the shaft or the outside air from leaking into the pump shell, the mechanical seal is mainly sealed by the relative movement of the end face between the movable ring arranged on the shaft and the static ring fixed on the pump shell, when the self-cooling water pipe is blocked and interrupted, the self-cooling water pipe is damaged and leaks water due to overhigh temperature, and the cooling water pipe is blocked and the mechanical seal is damaged due to more sludge and impurities in sewage, so that a centrifugal pump mechanical seal water cooling system for a sewage plant is provided to solve the problem.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the shortcoming that exists among the prior art, and the centrifugal pump machine seals water cooling system for sewage plant that proposes has changed that sewage centrifugal pump cooling effect is poor, easy jam burns the bearing seal, influences sewage treatment system safety and economy operation, can effectively improve bearing seal life, improves the running condition of equipment.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the design is a centrifugal pump machine seals water cooling system for sewage plant, including the clean water basin, clean water basin one side is provided with the clear liquid pond, one side that the clear liquid pond was kept away from to the clean water basin is provided with the concentrate pond, the female pipe of clear liquid pond fixedly connected with clear liquid cooling pump entry, the female pipe fixedly connected with machine of clear liquid cooling pump entry seals the cooling booster pump.
Preferably, the machine seal cooling booster pump is fixedly connected with a machine seal cooling water pipe, and the machine seal cooling water pipe is fixedly connected with a clear water recycling pipe.
Preferably, the clear liquid cooling pump inlet main pipe is fixedly connected with two clear liquid cooling pumps.
The utility model provides a, beneficial effect lies in: the centrifugal pump machine of the sewage treatment plant seals the water cooling system, does not need extra water source, uses the reclaimed water after the sewage treatment plant purification as the water source, does not have the additional heat exchanger, and the cooling water enters the biochemical treatment system after the heat transfer, does not produce secondary pollution, and is safe, economic and environment-friendly.
Compared with the prior art, the utility model has the advantages of reasonable design, and the practicality is strong, surveys many times and system analysis, demolishs former self-cooling water pipe, and the drainage end seals up, inserts through system's processing back normal water as the cooling water former, through this optimization transformation, has solved the machine and has sealed the damage problem.
