Climate resistant, corrosion-resistant and rust resistant. The inner plate is hot-dip galvanized, which is also corrosion-resistant and rust-proof. The middle part is filled with rigid polyurethane foaming agent and evenly mixed for foaming,
The inner and outer box plates are closely combined, the heat preservation performance is good, the box plate structure is solid and the sound insulation / vibration isolation performance is good.
■ structural design
● the box plate shall be fixed by a rotating lock without screws, which is convenient for disassembly and maintenance.
● the base with solid channel steel or steel plate bending shall be installed at the bottom, so that the whole machine will not be deformed during transportation and hoisting, and it is safer.
■ heat exchange coil structure
● the heat exchange tube is arranged in the form of positive triangle and cross row, and the number of rows is generally 4-8 rows; the heat exchange tube is high-quality and high-purity copper tube (TP2).
The high-efficiency heat exchanger is manufactured by the assembly line of oak company in the
It can meet the requirements of thermal performance in different occasions; precise processing machinery and strict process control ensure the uniform sheet distance and tight expansion.
The outer frame of coil is made of galvanized steel plate, which is firm and durable. The connection is connected by bolts to avoid the damage of galvanized layer during welding
Rust phenomenon.
■ coil design
Adopt different internal process design according to different flow / temperature difference and working conditions, so as to keep the heat exchange performance and water pressure drop of coil in a reasonable and efficient range, and reduce the difficulty in engineering application.
● the design head-on wind speed is 2.5m/s-2.8m/s; it can also be specially designed as required.
■ fans and motors
The fan adopts double inlet centrifugal high-efficiency fan, the volute is made of high-quality galvanized steel plate, and the side plate has a well-designed streamline shape and phase coordinated advance
The tuyere and side plate are punched once to form a disk aid, with high rigidity and no fatigue damage; the external frame structure of the blower is fixed, with high strength and stable operation
Fixed, small vibration; the fan impeller is made of high-quality steel plate into a specific streamline shape, and each impeller is in accordance with the internal control static / dynamic balance grade higher than the national standard all inspection passed.
The fan bearings are all international famous brand products, the bearing type is air tight ball bearing, pre lubricated and self-aligning, normal use maintenance free during the period.
The fan shaft is made of C-45 steel through rough / finish machining / secondary tempering and rust prevention treatment, with high rigidity, strong fatigue and no rush maintenance is easy.
● the advanced technology and manufacturing process of the above fans are operated under the supervision of ISO9001 quality assurance system recognized by international authorities to ensure the quality of fans.
● when selecting and matching the fan, try to take the low speed fan as the main one, so as to minimize the noise and vibration when the air volume and air pressure requirements are also met.
High quality brand-name motor shall be selected for the motor matched with the fan, and the insulation level of the motor shall be class B, so as to ensure the quality and service life, and according to the user
It is required to use the designated brand motor or raise the vigilance of motor insulation to meet the needs of different occasions.
● the fan adopts belt drive, in which the belt adopts high-quality V-belt, and the belt pulley is processed precisely to ensure concentricity and accurate coordination with the belt;
After the fan and motor are assembled, the second actual operation and rotation balance check shall be conducted to achieve the lowest vibration and the highest transmission efficiency.
● the fan and motor base shall be designed and equipped with appropriate damping spring damper according to their operation characteristics, and the fan outlet and outer box shall be corrosion-resistant and waterproof canvas soft joint.
● this unit does not include fan start control cabinet, if necessary, it should be ordered separately.
■ filter
Double layer nylon concave convex net is adopted, which is convenient for replacement and disassembly, and can be cleaned and reused for many times. The air inlet can be equipped with a non-woven folded plate filter or a new return air mixing box as required.
● the dust capacity is large, and the dust capacity per square meter under the designed final resistance (twice the initial resistance) is more than 100g.
■ humidifier
● for air humidification, it can be added according to the user's requirements, but it may affect the overall dimension of the whole machine.
● different types of humidifiers can be configured according to the user's use occasions, including dry steam humidifier / electrode humidifier / electric humidifier;
High pressure spray humidifier / wet film humidifier, etc. the first three are isothermal humidification, and the latter two are equal enthalpy humidification.
● the dry steam humidifier requires the user to supply the steam source. After the dry steam humidifier is separated from the dry steam humidifier, the dry steam is ejected from the nozzle for humidification.
The electrode humidifier uses water to vaporize directly by the action of electrode, which is easy to control and adjust and can work in low and high temperature environment characteristic.
The electrode humidifier directly uses electric heating to make water boil and vaporize, which is easy to control and adjust and can work in low temperature and high humidity environment.
High pressure spray humidifier uses high pressure pump and atomizer to atomized water into tiny particles and spray into the airstream to absorb the heat in the air.
Humidification.
The wet film humidifier is a new type of wet film humidifier, which uses water to fully contact with air flow when it penetrates from the wet film downward
After exchange, it is directly vaporized and humidified.
Electrode type humidification / high pressure spray humidification and wet membrane humidification need stable replenish water sources.
