Buffer Tank For Air Source Heat Pump
Enamel water tanks, enamel water tanks, stainless steel water
tanks, galvanized water tanks, waterproof tanks and other products.
The high-strength enamel steel water tank is a new type of water
tank assembled by using HSC series enamel as the base glaze and top
glaze on the δ2-δ5 steel plate. The plates are fired. The
mechanical impact resistance of the porcelain layer is 4 to 5 times
higher than that of ordinary daily-use enamelware. It is
acid-resistant, alkali-resistant, impermeable, and leak-proof. It
is a new technology for water tank corrosion protection.
Because of its superior performance in anti-corrosion, enamel liner
is replacing other liners and becoming the main force of water
heater liners.
Features of Buffer Tank For Air Source Heat Pump
1. The interior of the enamel water tank is clean and hygienic,
white and beautiful, to ensure that the water quality is not
polluted;
2. Rugged and durable. Reinforcing plates and stainless steel ties
are arranged at the joints of the four plates to enhance the
firmness and stability of the assembled enamel water tank;
3. The combined plates are assembled on site, which is convenient,
fast, flexible and adaptable;
4. Good impact resistance, earthquake resistance and long service
life;
5. Acid resistance, alkali resistance and corrosion resistance;
6. No leakage, no seepage, good sealing performance;
7. The storage of hot water is better than other water tanks
(heat-resistant rubber strips are required);
8. The interior of the enamel water tank is smooth and easy to
clean.
Production Process of Buffer Tank For Air Source Heat Pump
In the actual production process of the enamel liner, many
different defects will occur due to the use of a variety of raw
materials and different production processes. Among them, the most
influential aspects are as follows:
Steel plate is the most important extremely low material for enamel
liners. The quality of the steel plate must be selected according
to the requirements of the forming (deformation, welding, etc.),
enameling process and enameled products. The expansion coefficient
of enamel is 32x10 negative seventh power. The carbon content of
the selected plates is not higher than 0.08%. The presence of
manganese in steel increases the yield limit and strength limit of
the steel, while the elongation performance is reduced. Therefore,
the higher the manganese content, the greater the required
deformation force. For carbon steel, silicon and manganese are also
the residues of deoxidizers during smelting.
Steel plates with a silicon content of less than 0.37% can
generally be deep-drawn, but beyond this value, even steels with
very low carbon content will become hard and brittle, not suitable
for deep-drawing processing, and affect adhesion performance . The
presence of sulfides will affect the structure of the steel plate
to a large extent and promote the production of streaks, thereby
reducing the plasticity and toughness of the cost steel, that is,
reducing the cost of deep drawing performance, and bubbles and
pores will appear in the ceramic layer. Phosphorus dissolved in the
ferrite will significantly reduce the plasticity of the cost steel,
but will increase its strength and hardness. The phosphorus content
of the steel sheet for deep drawing should be as small as possible.
(<0.06%). Titanium added to steel is very beneficial to enamel.
Because it can combine with various components in enamel, the
adhesion is increased. The inner tank of the water heater is coated
at one time (wet flow coating, wet spray enamel, Electrostatic
powder spray enameling) titanium steel is an ideal substrate.
Aluminum-containing steel can be cast continuously, with less
component segregation and inclusions, good cold working ability,
and aging resistance. The biggest disadvantage is that it is easy
to appear fish scale defects after enamelling and reduce the cost
of adhesion strength. The thickness of the plate should be selected
as thick as possible to ensure that the inner liner has sufficient
thickness. Only by choosing high-quality enamel plates can the
enamel quality of the inner tank be guaranteed and the service life
of the inner tank can be guaranteed.
Enamel steel water tanks can be widely used in hotels, buildings,
restaurants, scientific research and teaching buildings, offices,
agencies, troops, garden villas, residential quarters,
entertainment venues and other public buildings, medical and
health, food processing and other secondary water supply places. It
is extremely convenient for the transformation or renewal of the
storage tank of the old building.
Installation and commissioning of prefabricated enamel steel water
tank
The foundation of the prefabricated enameled steel water tank can
be made of concrete strip beams or I-beams. The top of the water
tank is equipped with a breathable air filter device on the
diagonal. The specifications and quantities are determined by the
manufacturer according to the size of the inlet. Lajin is used
inside the water tank. All nozzle flanges are 1.0MPa standard
flanges. When arranging the location of the water tank, the
designer should refer to the GB17051-1997 sanitary code for
secondary water supply facilities. When the technical parameters or
orientation of the water tank are not suitable for actual use, the
designer shall propose and determine it according to actual needs.
The production process of the combined enamel steel water tank:
Q235 carbon steel plate shear trigger cutting -> first
continuous die workpiece convex round (square) stretching ->
shear trigger cut all four sides -> punch down four corners
-> second continuous die The workpiece is flanged and formed
-> four corner welding -> punching -> sandblasting and
rust removal -> enamel -> sintering -> the overall
assembly is completed.
Manufacturing standards of Buffer Tank For Air Source Heat Pump
(Refer to the national standard GB02S101 manufacturing)
Compared with the prefabricated galvanized water tank, the
assembled enameled steel water tank has exactly the same assembly
method of the box structure, and the difference lies in the
anti-corrosion method.
The prefabricated enamel steel water tank adopts advanced
technology, high-quality materials are selected, and the enamel is
sintered at high temperature to form a dense glaze layer on the
surface of the water tank, which penetrates between the ions at the
interface of the steel plate, and mixes to form a diffusion layer
with a thickness of about 200-300 microns. The adhesion strength of
the enamel surface is improved. The porcelain surface is smooth,
easy to clean, and corrosion-resistant. The steel plate assembly
structure is not easy to deform, has strong shock resistance and
high impact resistance. Through long-term and extensive use, it
shows good results and is well received by users.
The enamel steel water tank is made of high-quality plates, made
into a single plate of different specifications (1m × lm, lm ×
0.5m, 0.5m × 0.5m), and then assembled. The relevant parameters of
this product are designed on the basis of the "Code for Design of
Building Water Supply and Drainage" (GBJ15-88), and the sanitary
indicators of this series of products have been appraised by the
Beijing Municipal Health and Anti-epidemic Department, and all meet
the "Drinking Water Hygiene Standards" GB5749-85, this series of
water tanks has the advantages of flexible on-site assembly,
non-deformation, strong shock resistance, corrosion resistance,
easy cleaning and long service life.
Installation and commissioning
installation of Buffer Tank For Air Source Heat Pump
1. When installing, leave a maintenance space of no less than 800mm
between the box and the wall, and the top and bottom of the box
should not be less than 500mm.
2. Make concrete braces first during civil construction, (the
braces need to be horizontal) the edge joints between the water
tank and the standard blocks at the bottom of the tank should be
located on the braces.
3. After the assembly is completed, close the outlet pipe and the
drain pipe, open the inlet pipe, and check while draining the water
until the water tank is full and there is no leakage before it can
be delivered to Party A for use after 24 hours.
