Product Description
Advanced Ceramic Acid Pumps is a large-flow, low-lift, cantilever
single-stage centrifugal pump. Particularly suitable for conveying
highly abrasive and corrosive media. Its core technology is based
on the metal efficient hydraulic model, using CFD design means,
using the solid-liquid two-phase flow hydraulic design method,
unique "ceramic + metal" composite manufacturing process.
Ceramic material
Ceramic materials are professional and reliable. According to the
characteristics of the conveying slurry, a ceramic material with
high strength, wear resistance and corrosion resistance was
developed. The unique injection molding technology was used to
ensure the reliability of the combination of ceramic materials and
metal components. The abrasion resistance test of the comparative
material of the Institute of Casting and Wear-resistant Materials
of Xi'an Jiaotong University shows that the wear resistance of
silicon carbide ceramic material is 3.5 times higher than that of
high chromium alloy (Cr*0).
2.2 Ceramic pump lining
With optimized design and special manufacturing processing
technology, silicon carbide ceramics are used for the pump housing
and the pump cover lining. The external use of metal armor makes
the pump highly reliable, safe, and easy to disassemble and
install. The special ingredients and technology of ceramic
materials ensure that the metal shell and the ceramic lining are
integrated and tightly combined.
2.3 Ceramic impeller
The impeller is an in-line metal hub structure and the outer
complex silicon carbide ceramic is manufactured as a whole.
Fundamentally ensured the mechanical strength of the impeller and
the wear and erosion of the crucible.
The impeller can be adjusted axially to maintain the impeller in a
reasonable position in the pump chamber, thus ensuring that the
pump operation is always in an efficient and stable state.
2.4 Shaft seal
The seal can move axially as a whole. The mechanical seal ring can
move axially, and the mechanical seal static ring is fixed on the
pump casing. It is better than the foreign product. The mechanical
seal static ring is fixed on the front cover of the bearing
chamber, which can avoid the radial runout of the mechanical seal
after adjustment and lead to the mechanical seal. damage.
2.5 Pump Structure
The Ceramic Acid Pumps design uses a back-pull structure. When
disassembling the impeller, mechanical seal and shaft assembly
during maintenance, it is not necessary to disassemble the entire
pump. The bearings are lubricated with oil to ensure stable
operation. The bearing part is composed of a bearing bracket and a
bearing body. The bearing body can be moved axially on the bearing
bracket to facilitate adjustment of the clearance and position of
the impeller.

1) Domestic initiative. Large-scale ceramic desulfurization
pumps are a blank in China, and advanced ceramic desulfurization
pumps are the first in China.
2) The performance is stable without attenuation. In the initial
operation, the performance of the pump is comparable to that of
other domestic manufacturers. However, the ceramic pump can be
basically not worn during the entire life cycle, and it can ensure
stable performance without attenuation.
Has outstanding advantages.
3) Abrasion resistance and corrosion resistance are good. Material
wear and corrosion tests have shown that the comprehensive
corrosion resistance of ceramic materials with silicon carbide as
the main component is more than 3,5 times higher than that of
high-grade alloys (Cr*0).
4) Efficiency does not decay. During the entire life cycle, the
efficiency of the advanced ceramic desulfurization pump does not
decrease. The continuous running time is better than that of the
metal pump. Especially, the metal pump will not be reduced in
efficiency due to gap leakage during the later period of
operation.
5) High security and reliability. The advanced ceramic
desulfurization pump has better continuous operation reliability
than the metal pump. The ceramic impeller can continue to operate
for more than 7 years and the system can be safely operated for
more than *0 years. Its service life is much higher than other
types of desulfurization pumps.
6) Easy maintenance and low maintenance costs. When the ceramic
parts of the advanced ceramic desulfurization pump are damaged by
external damage, they can be repaired at the site or returned to
the manufacturer according to the situation, and the whole part
need not be scrapped, which greatly reduces the maintenance cost
and time.
Conclusion: The unique wear resistance and corrosion resistance of
ACP's advanced ceramic desulfurization pump not only has a long
life and a wide range of application that metal pumps cannot match,
but also has extremely high efficiency in terms of energy saving,
reduced maintenance, and reduced operating costs. obvious
advantage.
I. Long-term operating efficiency does not decay means saving
current:
Take Huaneng Yingkou Power Plant as an example:
The initial efficiency reaches the foreign product efficiency
level, and the average efficiency after long-term operation is 2%
higher than that of a German company's product -
6%;
Annual energy saving calculation formula: *4 hours X**0 days

Single pump power up to *0.*9 million kWh. According to the
Liaoning on-grid tariff of 0.***4 yuan/kWh, the savings in
electricity charges S.*1 million was calculated. Two power station
units 2 towers, S-slurry circulation pump saves 6S.SS yuan per
year, and it can save 3.**4 million yuan in five years.
2, to protect more than five years without maintenance, no
replacement parts, save maintenance costs:
Take a **0kW slurry circulating pump as an example:
Calculated according to the 2 tower S pump, spare parts can be
saved within five years (****0) XS = ***4S0 million (domestic
production of impellers need to riCI million, before and after the
shields need about **5 million, according to five years replacement
Calculations for three sets of impellers and three sets of front
and rear guard plates required five years for a pump (****0) X 3 =
****0 million yuan for spare parts).
The above two items total savings of **0. *****3. 2 million.

1) The performance of the Ceramic Acid Pumps is quite
equivalent, and it can completely replace the imported helium from
the power plant (**0MW unit / desulfurization pump actual operation
record shows that taking the current and outlet pressure as an
example, the advanced ceramic desulfurization spring completely
exceeds the performance of the KSB desulfurization pump ◊
2) Erosion and corrosion of niobium are superior to metallic ones.
According to the survey of the power plant, the ceramic impeller
has better wear and corrosion than the A*9 and Noridur das. The
service life of the sealing impeller is much less than that of the
ceramic impeller. (Metal impeller 3 to 5 years, ceramic impeller 7
More than one year
3) Efficiency does not decay. During the entire life cycle, the
hydraulic efficiency of the ceramic pump does not decrease. The
continuous safe operation time is much higher than that of the
metal pump, and in particular, the metal pump will not be reduced
in efficiency due to the increase in clearance leakage at the later
stage of operation.
4) Long continuous safe operation. The German Dnechting Ceramic
Impeller is continuously operated for 3 to 5 years without damage.
Even if it is not accidentally damaged, it can be repaired with a
regeneration process. The service life is far higher than the metal
pump. 1 The company's advanced ceramics were put into operation and
operated stably and without any abrasion.
5) The abrasion resistance is better than the rubber lining type.
After the rubber lining is worn out by the liquid, the damaged
rubber particles can easily fall off, resulting in blockage of the
nozzle of the absorption tower, reducing the desulfurization
efficiency and affecting the reliability of the pump.
6) Easy maintenance and low maintenance costs. Easy maintenance,
when the ceramic parts are damaged, they can be repaired on the
spot or returned to the factory according to the situation, without
the need to scrap the entire parts, greatly reducing maintenance
costs and time.
Conclusion: cost-effective. Advanced ceramic desulfurization pumps
are more cost-effective than imported pumps, and the price is
*0°/percent for similar inlet pumps. **0%, and the service is the
best and the most convenient during the entire operation period.
