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 is drafted by the IEC (International Electrotechnical Commission). Electrical appliances are classified according to their dust - proof and moisture - proof properties. IP protection grade is composed of two numbers, the first number represents the lamp from the dust, to prevent the invasion of foreign objects, the second number represents the lamp against moisture, waterproof invasion of the airtight degree, the greater the number means that the protection grade is higher. The meaning of the first number: 0: no protection, no special protection 1: the protection of the solid more than 50mm, can prevent the diameter of more than 50mm of solid foreign bodies into the shell. It can prevent a large area of the human body (such as the hand) from accidentally or accidentally touching the charged or moving part of the shell, but can not prevent the conscious approach to these parts 2: protection of solids greater than 12mm, can prevent the diameter of the larger than 12mm of solid foreign bodies into the shell. Can prevent fingers from touching the charged or moving part of the shell ①3: protection of more than 2.5mm of solid, can prevent the diameter of more than 2.5mm of solid foreign bodies into the shell. Can prevent the thickness or diameter of more than 2.5mm tools, metal wire and so on touching the charged or moving part of the shell ①②4: protection of more than 1mm of solid, can prevent the diameter of more than 1mm of solid foreign bodies into the shell. Can prevent the diameter or thickness of more than 1mm wire or strip touching the live or running part of the shell ①②5: dustproof, can prevent dust from entering to affect the normal operation of the product, completely prevent touching the live or moving part of the shell. 6: dust tight, can completely prevent dust from entering the shell, completely prevent hit shell charged or exercise part of the meaning of the second number: 0: no protection, there is no specific protective 1: drip-proof, vertical drop of water should not go into the motor internal 2:15 o drip-proof, with a plumb line into 15 o Angle within the scope of drop water, should not directly into the motor internal 3: water spray, water and the plumb line into 60 o Angle within the scope of the spray water, should not go into the motor internal 4: splash, splash water on any direction motor should be no harmful effects 5: water spray, spray any direction for motor should be no harmful effects 6: Prevent water waves or impose, violent waves or strong water should be no harmful effects on the motor 7: flooding, motor under pressure and time stipulated in the submerged in the water, the water inflow should be no harmful effect on 8: scuba diving, motor in the provisions under the pressure of the long soak in the water, the water inflow should have no harmful effects commonly used in the application of motor protection grade IP11, IP21, IP22, IP23, IP44, IP54 or IP55, etc.
