The waste heat generated in industrial production or refrigeration process is generally guided away by cooling water. The function of FRP cooling tower is to exchange heat between the cooling water carrying waste heat and the air in the tower, so that the waste heat is transmitted to the air and dispersed into the atmosphere. For example, in a thermal power plant, the boiler heats the water into high-temperature and high-pressure steam, drives the steam turbine to do work to make the generator generate electricity, and the waste steam after the steam is discharged into the condenser, heat exchange with cooling water to condense into water, and then pump back to the boiler for circulation. In this process, the waste heat of exhaust steam is transferred to the cooling water, which increases the temperature of the water. The cooling water with waste heat is transferred to the air in the FRP cooling tower and discharged into the atmospheric environment from the air duct.
What should be paid attention to when using glass steel cooling tower.
1. When using FRP cooling tower, you should always observe and check the operation of the fan, including current, voltage, fan vibration, noise, gear oil level, whether there is oil leakage or whether the belt drive is loose, whether there is slippage, whether the water distribution is normal, etc.
2. The cooling tower gearbox uses 20# mechanical oil or gear oil. In addition to continuously filling the glass fiber reinforced plastic cooling tower to the specified oil level, it should be replaced every year of continuous operation.
3, glass fiber reinforced plastic cooling tower belt drive bearing seat, to add lubricating grease, usually with a grease gun to fill once a month, every year of continuous operation, all dismantled and replaced once, always pay attention to the connecting parts, bolt fastening.
Today, I would like to share with you the preparation before use and maintenance during operation of the FRP cooling tower. In order to enable the FRP cooling tower to perform its best function and thus prolong the service life of the FRP cooling tower, good inspection and maintenance must be done. Under normal circumstances, it is necessary to conduct a comprehensive observation of the FRP cooling tower every day to ensure its normal operation.
The FRP cooling tower needs to be fully inspected and cleaned when working, and the working part needs to be inspected in more detail. It can only be carried out after there is no problem. After entering the cooling tower through the inspection door, it needs to clean up the debris and sludge on the bottom basin of the cooling tower, and also check whether the pipeline is blocked, high-pressure water is used to wash the heat dissipation film and the soil on the bottom basin of the cooling tower, and the sewage is discharged through its drain outlet. It is also necessary to check whether the wiring of the motor is correct, check how tight the belt in the belt drive equipment of the FRP cooling tower is, check whether the rotation of the fan is relatively flexible, etc. The internal modification of the FRP cooling tower is to improve the quality of FRP by using high-reinforced plastic resin matrix and reinforcing fiber additives, this method has high cost. FRP products have limited their application due to their weather resistance, poor wear resistance and low hardness. The market needs FRP products with good appearance and high cost performance. There are two ways to solve the defects of FRP products: internal modification and surface coating, and surface coating: during or after the forming of FRP products, various products are used, materials with high performance or a specific function are used to modify the surface of the cooling tower, protect or give new functions, and improve the quality and competitiveness of the products.
The surface is of high quality and multi-function, and there is no need to change the formula and process conditions of FRP products. Most FRP surface coating protection adopts simple methods such as painting or gel coating, but the quality is poor and requires frequent maintenance. High-performance FRP surface protection refers to coating technology with high decoration, heavy corrosion protection, super weather resistance, functionalization and easy construction.
High-performance FRP surface protection has the following requirements: coating (environmental protection): water-based coating, powder coating, high solid content and solvent-free coating. Six factors to be considered in selecting coating: coating purpose, working environment, construction conditions, adherence to the principle of "saving", matching and environmental protection requirements. At present, FRP surface coating processes with development prospects include: dipping plastic is suitable for small and regular workpieces, spraying is suitable for workpieces with large surface area and regular shape. Using this method to paint FRP products, the coating surface quality is good and the investment is not high.
