Mode, hot water circulating pump absorbs water in drum, then force squeeze into water beam upright post system after, the most again
Return in drum.Latter approach is relatively low to design and construction requirement, the safety of operation, the most steady
Qualitative higher, apply the most universal.
Hot water circulating pump operation principle in latter approach is common centrifugal water pump principle, simply by
The water pump that the medium temperature of conveying is more general when work is high, in order to extend the service life of hot water circulating pump,
The sealing of hot water circulating pump need to be cooled.
In prior art, using clean circulating water as cooling medium, clean circulating water comes from for line configuration
The high pressure of clean circulating water pipeline surveys water inlet supervisor, and the coolant intake in cooling chamber through connecting with water inlet pipe enters
Enter cooling chamber interior so that the sealing in cooling chamber to be cooled down, after complete rear cooling, the cooling on cooled room
Outlet is expelled in return pipe, eventually passes back in the low pressure return pipe of clean circulating water pipeline, it is achieved circulate cold
But act on.
Owing to employing clean circulating water is as cooling medium, and clean circulating water is not to soften water, and its hardness is higher, contains
There is calcium ions and magnesium ions；And the pressure of clean circulating water is the highest, it is used for the clean of hot water circuit pump seal cooling at least
Ring water pressure can not be the highest, if at this, clean circulating water pressure is higher than pressure in the pump housing of hot water circulating pump, then
Clean circulating water can scurry into water softening system in pump, causes demineralized water the most up to standard, consequently, it is possible to cause bigger
Equipment breakdown.
Owing to clean circulating water pressure is the highest, and wherein possibly together with the more calcium ions and magnesium ions causing fouling, that
First, in return pipe, residue vapor (being formed after high-temperature high pressure water decompression) promotes channel interior fouling,
Being reduced by aperture after fouling, the cooling water inflow entered in cooling chamber (or claiming pump seal chamber) to reduce,
After cooling water inflow reduces, quantity of steam to increase therewith, and then promotes that scale velocity improves, soon by backwater
Pipeline blockage；After return pipe blocking, because in pump housing, pressure is more than cooling clean circulating water pressure, the purest
Pure high-temperature steam countercurrently to arrive in the water inlet pipe sealing cooling, same principle blocking water inlet pipe；Along with
The prolongation of time, in cooling chamber, fouling is not wanted in cooling yet, simultaneously because seal not cooling, filler is close
Envelope premature degradation, and mechanical seal is too high due to operating temperature, to be also quickly damaged, pump starts to leak steam
And water；Owing to not having water to lower the temperature pump shaft bearing, the equipment fault of bearing damage locking is along with possible
Occur.Now it is necessary for the problems referred to above are carried out termination of pumping process.
For above-mentioned reasons, we substitute circulating pump in regular maintenance frequently, are replaced pipeline
Clearing up with to sealing cavity, labor intensity is big, spare parts consumption is high, reduces making of hot water circulating pump
Use the life-span.
