Product Description
General explanation
All cooling towers of Yatai are energy saving type, for the motor installed load is lower than that of similar cooling tower at home and abroad. The water temperature drop of the silent and the super-silent is generally 3~8ºC, suits in the ordinary water cooling such as air conditioning chiller and so on.
A series of noise control measures have been taken in the super-silent cooling tower on the base of the silent one, the noise value at standard point is lower as many as 5dB(A) than the corresponding silent one. It suits in the place where noise is controlled strictly such as hotel , hospital, public construction and the place which is near to the inhabited area. Its foundation, pipe diameter, motor power, cooling water capacity and air flow are the same as those of silent ones.
The water temperature drop of the industry type, namely middle or high temperature cooling tower, is generally 10~25ºC. Lots of measures on this type has been taken such as increasing body diameter, air flow rate, air pressure, power, packing height and so on. It suits in industrial cooling, large temperature drop is necessary. Its thermal performance values are surplus when designing, therefore, please do not have mercy on them when selecting. Its code means is as follows: DBNL3-100 type: D-silent, B-Glass fiber reinforced plastic, N-Countercurrent type, L-Cooling tower, 3-The third modification design, 100-The nominal flow rate is 100m3/h at standard working condition. GBNL3-100 type: G-Industrial type middle/high temperature drop. CDBNL3-100 type: CD-Super-silent type, the others are same as the above.
The Fourth Design Research Institute of Chinese Machinery Electronic Industry Ministry started to be engaged in researching and promoting of cooling tower in 1971, and has obtained outstanding prizes and significant scientific research awards of the Ministry, Province and City many times.
The energy saving silent or super silent industrial cooling tower was co-designed by the Fourth Design Research Institute of Chinese Machinery Electronic Industry Ministry and Qinghua University together on the base of summarizing the BNL series (in 1980) and absorption the advanced technology at home and abroad. The sound absorption measure of the super silent was co-researched with Beijing Labor Protection Research Institute. Due to its little drifting water, its performance surpasses that of similar one at home and abroad and is one of the most ideal water saving equipment.
Round countercurrent cooling tower's components
Motor: The Motor Department of Qinghua University designed a special silent and energy-saving motor for cooling tower on the base of installation size of Y series of motor. It has many features like good seal, refractory, efficient and silent.Fan: The Engineering Department of Qinghua University designed a silent and efficient fan made of aluminum board or wing-shaped FRP blade.Rotary water distributor: The water distributor rotates nimbly and reliably, its head pressure is low and water distribution is uniform, Take aluminum or FRP pipe as water pipe and mount water-receiving-board on it to overcome water drifting.Packing: Modified PVC oblique-wave sheet, good water redistribution capacity, small resistance, fine thermal performance, 70ºC to -50ºC of temperature tolerance range, perfect flame-resistance.Sound absorption devices: Screen with sound absorption material is fixed at air inlet and joint of upper and lower bodies of the super-silent cooling towel to get the perfect noise-reducing effect.Support: All the supports of fan, packing, air intake, body and so on are assembly type, galvanized or painted. All the fasteners are galvanized or stainless steel bolts.Speed brake: Equipped with belt made of chloroprene rubber reinforced by polyester fiber, and has many features like refractory, efficient, silent, no extension when wet, no slipping and so on.Sound absorption measures: Flared screen with sound-absorption material or sound-absorption grill is fixed at air outlet of the upper body of the super-silent cooling tower, it reduces fan and motor noise.Upper body: Has many features like streamlined, smooth air flow, bright color, aging resistant, high strength, light weight and anti-corrosion due to there being anti-ultraviolet ray agency in the superficial rubber resin.Air intake: Equipped with FRP louver to reduce water splashing and air resistance.Lower body: "Water spill pipe"," waste drainage pipe" and "automatic water supply pipe" are available according to the ordering requirements, you can also suck water here and cancel water cooling pool.
Notice on selection and operation
When selecting, you shall know water flow rate (Q), water inlet temperature (t1), water outlet temperature (t2) and design wet-bulb temperature (t), choose model according to the thermal performance curve. If beyond the curve, you can send the requirements to the Fourth Design Research Institute, and let it give you a hand for choosing model.As for the material freeze resistance, it can be used at -50ºC zone. As for the zone where the average temperature of coldest month is lower than -10ºC, freeze-proof measures should be given when placing order, and shower diversion groove should be available before delivery to avoid water dripping on the louver.The circulation water opacity shall be less than 50mg/L or less than 100mg/L in short-term. There shall be no greasy dirt or mechanical impurity in the water. If necessary, take algae-extinguished and water-quality-stabilized measures.The base drawing is for reference when installing, boil hole should be reserved or base anchor should be embedded in advance. The water pipe direction of the large-sized tower can see the diagram, that of small-sized tower can be at any horizontal direction, but mustn't touch the base. If there being base at middle, its load bearing shall be 25% of the running weight, the other 75% weight shall be evenly born by the periphery rectangle base. If installed on roof, wind load shall be considered as additional pressure.As for the cooling tower smaller than 125 model, a support shall be available at the connection between external water inlet/outlet pipe and tower to prevent too many weight loading on tower wall.The aperture for joining water-distribution pipe should be opened according to nominal water flow rate, if the difference between real and nominal is over ±15%, please let us know when placing order ,we can change the aperture's diameter. The hydraulic pressure at inlet is about 2~5m water columns, it shall not be excessive when designing, or else its drift loss will increase due to excessive water flow rate.The water temperature shall be less than 60ºC. If outnumber, please let us know when placing order, we will choose proper material to make it. If needing flame-resistant type, you should remark when ordering, we can meet.If sucking water directly from the tower, shall fix "automatic water supply pipe"," rapid water supply pipe"," waste drainage pipe", please remark when placing order, out quotation doesn't cost those costs.As for the cooling tower bigger than 150 model, its blade angle can be adjusted, but their degrees must be same. Its electric current shall not outnumber motor rated one. All kinds of fan can melt ice by contra-rotating in short time, therefore, a reversible magnetic starter should be fixed near the tower in severe icing zone. (As for the blade adjustment, please see the manual instruction of crosscurrent glass fiber reinforced plastic cooling tower )When starting cooling tower, must turn on water pump first, then fan, running fan at no shower is forbidden. When stopping, must turn off fan first, then water pump.
