The belt of the industrial cooling tower fan is slightly elongated at the beginning of operation, and the belt tightness should be adjusted appropriately. If it is too tight, it will cause an accident and damage the bearing.
When the industrial cooling tower is running, the bearing of the cooling tower fan is refueled, the motor is covered, the belt is tight and the nut is locked during operation, and whether there is a bird's nest or foreign matter in the tower is also confirmed before starting up and running.
After the circulating water in the industrial cooling tower evaporates, it will leave the dissolved substances in the water, which will increase the water concentration, increase the corrosion after the water is concentrated, increase the scale, and make the cooling tower capacity low, and damage the piping and equipment.
About the industrial cooling tower for you to explain here, if you want to know more wonderful information, welcome to check our website update, more wonderful information we will continue to organize for you.
1. Cleaning: Detailed inspection, analysis of leakage, determination of the location of grouting holes and the distance between cooling towers, clean up the area to be constructed, chisel out the precipitates on the concrete surface, and ensure that the surface is clean.
2. Drilling: Use drilling tools to drill pressure relief holes along the periphery of the hole. The diameter of the drill bit is 14mm, the drilling angle should be ≦ 45, and the drilling depth ≦ 2/3 of the thickness of the structure. The drilling must obliquely pass through the main leakage hole, but the structure must not be punched through. Dust in the hole with large moving water will be washed clean by itself. If the wall surface is slow to penetrate, plum blossom holes are drilled respectively on the seepage surface, the grouting with a cleaning machine, the next step can be carried out until the water out of the grouting hole is clear.
3. Burying nozzle: observe the pressure of the main water leakage hole. When the water flow is not rapid and the pressure is not high, the quick-drying leakage plugging agent can be used to bury the grouting water stop needle (according to the construction situation, the wooden wedge can also be driven and then blocked with the quick-drying leakage plugging agent. After the structure is stable, the wooden wedge can be drilled again and the expansion water stop needle can be installed in other water leakage holes respectively, there is no gap between the grouting mouth and the drilling hole, and there is no water leakage. Expansion water stop needles are also installed in turn for slow seepage on the wall surface. Water leakage points are respectively installed with 25CM,10CM and 8CM water stop needles according to hierarchical dislocation, so that the grouting can be completely dense from the deep layer to the surface layer, blocking all holes and gaps.
4. Grouting: use high-pressure grouting machine to test the pressure, which shall not exceed the compression range of the concrete structure, pour chemical grouting material into the grouting hole, and carry out single hole one by one continuously. when the adjacent hole starts to discharge grout, keep the pressure for 3~5 minutes, then stop the grouting of this hole and change the adjacent grouting hole. after all holes are filled, return to the previous first grouting hole and grout again to ensure maximum pressure, the grouting sequence of the wall surface is from bottom to top. After all the holes are filled, the cooling tower will also return to the previous first grouting hole for recharge.
5. Mouth removal: After grouting is completed for 24 hours, the exposed grouting mouth can be removed or knocked off after confirming that there is no leakage, and the solidified spilled grouting liquid can be cleaned up.
6. Reinforcement: Use anti-leakage cement-based permeable crystalline compressive sealant for comprehensive blocking or rigid RG material plastering for protective layer enhancement, and finally use polymer JS waterproof coating to coat three times for surface waterproof treatment (applicable to overall blocking, for reference only).
Scope of application: plugging with water and pressure, subway, tunnel, pump room, reservoir, sewage pool, underground civil air defense cave, basement garage plugging, cable ditch, culvert, dam, power plant dam, acid (alkali) pool plugging, cooling tower plugging, seepage prevention, leakage prevention, leakage prevention, leakage plugging, concrete engineering cracks, expansion joints, construction joints, grouting of structural joints sealing and leakage plugging of exterior walls.
