关于Zhongliang YijiCooling Tower Maintenance Tips and Practical Servicing Methods:
( 1 )做好各部件及工作流程的运转记载
玻璃钢冷却塔缔造或设备竣工投入运转时,规划单位或出产制作厂家应供给凉水塔的悉数特性数据:包含热力特性、阻力特性、水负荷、热负荷、环境Temperature(干、Wet-Bulb Temperature)、冷却范围、空气流率、Power耗费、风吹失、蒸发水量、弥补水量、浓缩倍率、Fan动力耗费、进塔的水压等,运用单位的有关分担部分应根据上述规划单位或出产制作厂家应供给冷却塔的悉数特性数据及各项内容做好运转记载。
( 2 )为检测玻璃钢冷却塔的运转作用,和其冷却才能的巨细,须进行室内实验或者在出产现场对运转中的冷却塔进行鉴定性测验。要想确保玻璃钢凉水塔的正常运转,不积要有冷却塔实验研讨的科技人员,还要有一整套较完好又契合标准的测验办法,而且有必要配备一套测验仪器及外表,如Temperature计、微压计、励计、声级仪等。
( 3 )冷却塔冷水集水池应坚持水池的水深,避免发作气蚀现象,集水池的干舷高度为15~30cm,以下为水池的有用容积,冷水集水池的水位应维持在一个固定的水平， 需求根据需求调理弥补水阀门。关于横流式冷却塔而言,如运转水位低于规划要求时,应在原水面以下设备空气挡板,避兔空l气旁流。冷水池应进行不定期的清扫以去除沉积于池底的淤泥及粘着物,铲除填料及支架掉落的碎屑,坚持Water Pump吸水口的格栅清洁,不定期地查看集水池的走漏,有必要要注意酸、水质安稳药剂分配设备是否正常运转。弥补水量、排泥与循环水的水质操控密切相关,应根据体系的要求及时调理投药量以坚持正常运转。

FAQ
How to choose between a closed-circuit and an open cooling tower?
For working conditions that demand clean water (such as vacuum furnaces, high-frequency furnaces, and injection machine hydraulic oil cooling), a closed-circuit tower is preferred: the cooled medium circulates inside the coil without direct contact with air, so it resists scaling, algae and particle contamination, with stable heat transfer and low maintenance. For ordinary recirculating water scenarios with tight water budgets or cost sensitivity, an open tower costs less upfront but requires supporting water treatment.
What are the footprint and connections of a 100 t closed-circuit cooling tower?
Taking a standard 100 m3/h closed-circuit tower as an example: overall dimensions are approximately 3500 x 1500 x 2800 mm with a footprint of about 5.25 m2; inlet and outlet piping is typically DN100, with a 5-10 C temperature drop under standard conditions. Refer to the product specification table for details; non-standard dimensions can be customised on site.
How do I size the pump and head for a cooling tower?
Pump flow is selected according to the rated circulating water volume of the cooling tower; head must account for pipeline friction losses, local resistance, equipment elevation difference and the necessary margin. Pressure-bearing equipment such as injection machines also requires reserve for the working pressure. It is recommended to hand the operating data (flow, temperature difference, installation height, pipe diameter and length) to technical staff for calculation, to avoid an undersized pump or excessive head that wastes energy.
What water treatment does a closed-circuit cooling tower need?
The outer circulating water of a closed-circuit tower still contacts air, so softened make-up water, periodic corrosion and scale inhibitor dosing, and control of the concentration ratio are recommended. The inner circulating medium should be softened water, antifreeze or pure water according to process requirements; outdoor installation in winter requires freeze protection (electric tracing or draining).
