At present, whether it is the machining industry or the manufacturing industry, there are many medium and large machinery and equipment in operation. These equipment are operating around the clock, and the equipment will also generate a lot of heat when the equipment is in operation. In the case of very dense machines, the high temperature that appears is very scary, and the heat rejection system is also an indispensable stage in the manufacturing process. People use cooling towers to conduct the heat generated by the equipment and reduce their temperature. Let the machinery and equipment be fully utilized.
Vibration or noise during operation of FRP cooling towerThe factors that cause these mechanical failures are divided into: deformation or damage of the uranium in the equipment, unstable rotation; damage to the rolling bearing parts, impurities or lack of oil in the uranium rolling bearing, dry friction; loosening of the fan impeller screw or impact with other parts; cooling Loose connection of tower shell; low voltage, motor noise. The solution is to change the shaft, repair the rolling bearings, tighten the screws, repair the blades, and inspect the cooling tower shell and motor according to the detailed situation. The fan motor is overheated during operation.
The factors of these mechanical failures may be abnormal insulation of the motor, low voltage and phase loss control, resulting in increased current, short circuit of the motor and increased current. The solution is to repair the motor, check the power supply voltage, tighten the terminals and change the motor. In addition, the wrong angle of the fan impeller causes the load to be greater; the rolling bearing is damaged, the rolling bearing is not enough or the oil is not enough, which intensifies the friction; the operating temperature is too high to also affect the temperature of the motor. In these cases, the blade can be installed again, the rolling bearing can be repaired, and the high-temperature motor can be selected.
How to minimize the noise from cooling tower operation?1. Install another layer of sound insulation cotton on the existing cooling tower, so that no noise will occur, and it can also play a role in filtering.
2. Change the rotating shaft of the cooling tower motor to reduce its speed ratio, but increase the angle of the cooling tower fan. (The speed ratio is reduced, but the exhaust air volume will not be changed to achieve the original cooling effect).
3. Change the rolling bearing of the cooling tower reducer to make the reducer smoother in the operation link, and there will be no friction sound of the rolling bearing under the circumstances.
4. Install a silencing screen above the air outlet of the cooling tower to prevent noise from being transmitted to the outside.
These products of cooling towers are widely used in industrial daily life. The specific function of the products is to contact the cooling water of the cooling machinery in the tower to reduce heat generation, remove waste heat, and realize the purpose of cooling water recycling. Therefore, cooling towers Industrial production and safety play a very important role. It is not difficult to see that the future development will be broader, and under the circumstances will be favored by more people.
