Cooling tower structure

Heading	Directions
Steel structure	This series of cooling towers adopts an anti-corrosion design,and a large number of galvanized parts are used in the internal steel structure so that the internal structure has no corrosion parts and the equipment life is greatly extended.It saves the necessary maintenance costs and directly reduces the cost of the enterprise.The steel parts in the tower are motor brackets,packing brackets,center tubes,etc.The anti-corrosion problem is an important part of the quality assurance of the entire tower.To ensure quality,all the factory steel components are hot-dip galvanized for anti-corrosion treatment.
FRP shell	It adopts a glass fiber reinforced plastic shell,the overall thickness is 5mm,and the flame retardant oxygen index is≥40.Fully automatic spraying equipment is used for one-time production and molding.The product is beautiful and contains a large amount of glue.The shortcomings of uneven thickness and uneven density of hand-made cracks are eliminated.The material is made of 191#anticorrosive resin and fiber cloth and fiber felt produced by Shandong Fiberglass Group.
Waterproof motor	It adopts waterproof,moisture-proof,corrosion-resistant special Y series outdoor cooling tower motor,which has good sealing performance and is widely used in cooling tower environments under various conditions.The insulation class is F,the protection class reaches IP55,the motor working voltage is 380V,and the rated frequency is 50Hz.
Cooling fan	The airfoil type axial flow fan designed for the Department of Engineering Mechanics of Tsinghua University,the blade is made of aluminum alloy,and the blade adopts an adjustable hub,which can be angled according to the requirements.Reasonable aerodynamic force,high efficiency,large air volume,low noise,and corrosion resistance.The designed service life is 15 years.
Water distribution system	The rotating water distributor is used to distribute water,and the water distribution system has anti-clogging performance.The rotor is made of the aluminum alloy at one time,with a temperature resistance of 120℃.The working pressure is between 0.03-0.08mpa(that is,the head of 3-8 meters).This form of uniform water distribution and high heat dissipation efficiency.Sprinkler pipe material PVC
Cloth water turn head	With the use of a pipe-type water distribution system,the water distribution system has an anti-clogging performance.
Thermal filler	Packing is an important part of the cooling tower,and its efficiency depends on the degree of full contact between the cooling water and air in the packing.Our company uses multi-corrugated packing,which has a large water redistribution capacity,low resistance,and good thermal performance.The air can quickly take away the heat in the water.The unique filler flow channel enables the water flow to form a large area of flowing water film on the surface of the filler,prolongs the cooling time of the water in the filler,and improves the water cooling effect.The material is a new modified PVC material with a temperature resistance of 65°C.The performance of this product complies with the Ministry of Energy NDGJ88-89"Cooling Tower Plastic Sprinkling Filling Technical Regulations".
Pipe diameter	Inlet pipe diameter,outlet pipe diameter,automatic water replenishing ball valve,overflow port
Ladder outside the tower	The cooling tower is equipped with a climbing ladder,which is convenient for daily inspection and maintenance.

The motor protection grade reaches IP55

  IP(INGRESS PROTECTION)protection level system was drafted by IEC(INTERNATIONAL ELECTROTECHNICAL COMMISSION).The electrical appliances are classified according to their dust-proof and moisture-proof characteristics.The IP protection level is composed of two numbers.The first number indicates the degree of protection of the lamp from dust and the intrusion of foreign objects,and the second number indicates the degree of airtightness of the lamp against moisture and water intrusion.The larger the number,the higher the degree of protection.high.The meaning of the first number:0:no protection,no special protection 1:protection of solids larger than 50mm,can prevent solid foreign objects larger than 50mm in diameter from entering the shell.It can prevent a large part of the human body(such as hands)from accidentally or accidentally touching the life of moving parts of the shell,but it cannot prevent conscious access to these parts.2:Protects solids larger than 12mm,and can prevent solid foreign objects larger than 12mm in diameter from entering Inside the shell.Can prevent fingers from touching the life of moving parts of the shell①3:Protect solids larger than 2.5mm,and prevent solid foreign objects larger than 2.5mm from entering the shell.It can prevent tools and metal wires with a thickness or diameter greater than 2.5mm from touching the life of moving parts of the shell①②4:Protect solids larger than 1mm,and prevent solid foreign objects larger than 1mm from entering the shell.It can prevent wires or strips with a diameter or thickness greater than 1mm from touching the life of moving parts of the shell①②5:Dust-proof,can prevent dust from entering to the extent that it affects the normal operation of the product,and completely prevent touching the life of moving parts of the shell.6:Dust-tight,can completely prevent dust from entering the shell,and completely prevent touching the charged or moving parts in the shell.The meaning of the second number:0:no protection,no special protection 1:drip-proof,vertical drips should not enter directly Inside the motor 2:15o anti-dripping,dripping water within 15o angle to the vertical line should not enter the motor directly 3:anti-sprinkling,water dripping within 60o angle to the vertical line should not directly enter the motor Internal 4:Splash-proof,water splashing in any direction should have no harmful effect on the motor 5:Water spray-proof,water spraying in any direction should have no harmful effect on the motor 6:Anti-wave or forced water spray,violent sea waves or strong force The water spray should have no harmful effect on the motor.7:Soaking,the motor should be immersed in the water under the specified pressure and time,and its water intake should have no harmful effect.8:Diving,the motor should be immersed in the water for a long time under the specified pressure,and it will enter The amount of water should not have harmful effects.The commonly used protection levels in motor applications are IP11,IP21,IP22,IP23,IP44,IP54,IP55,etc.
