In order to maintain the cooling effect, the circular cooling tower should be maintained daily. Today, we share the daily maintenance points of the circular cooling tower.
(1) operation record
The circular cooling tower construction or installation completed and put into operation, the production of the manufacturer should provide all the characteristic data of cooling tower: including the thermodynamic characteristics, resistance characteristics, water load, heat load and environment temperature (dry and wet bulb temperature), cooling range, air flow rate, power consumption, air loss, water evaporation, water supplement and the concentration rate, fan power consumption, the water into the tower, the relevant departments in charge of the use of units should record the operating according to the above-mentioned contents.
(2) measuring instruments and methods
In order to test the operation effect of cooling tower, or evaluate the cooling capacity, it is necessary to carry out the indoor test or the production site to carry on the appraisal test to the cooling tower in operation. Therefore, not only to test and Study on cooling tower technology personnel, but also a set of relatively complete and consistent with the standard test method, and must be equipped with a set of test instruments and meters (some have spare), such as thermometer, pressure gauge, pressure gauge, level instrument etc..
(3) fan and its transmission device
Fan and drive shaft regularly check whether the blade surface damage or abnormal situation, check the drive shaft and shaft coupling, should maintain a horizontal straight line.
Gear reducer - regularly check the gear reducer oil level and oil wet, and use seasonal temporary parking, the oil exchange, check each part.
(4) cooling water sump
The cold water tank should keep the water depth in the tank, to prevent the occurrence of cavitation phenomenon, sump freeboard is 15~30cm, the effective volume of the pool, the pool water level should maintain a certain level, or need to adjust the water supplement valve. For the cross flow cooling tower, if the operating water level is lower than the design requirements, the air baffle should be installed below the original water surface to prevent the air flow. The cold water tank should be not regular cleaning with mud and adhesive removal of sediment at the bottom of the pool, clear the debris falling filler and support, maintain clean water pump inlet grille, not regularly check leakage of the collecting tank, such as the need to repair, must pay attention to acid, chlorine, the water quality stabilizing agent distribution device normal operation.
(5) hot water distribution system
In order to maintain the smooth flow of clean water system, including control valve, regulator device, pipe, nozzle, splash, adjust the distribution of tank pool water flow so as to get the same water depth (water depth between 100~150cm), if the cycle of water into the tower has a big change, with the water pipe, the nozzle should be done the corresponding adjustment.
