Maintenance is the most important factor that will effect the performance and service life of cooling tower. Here we introduce three steps of maintenance works of Newin Cooling Tower, they are: Inspection during operation; Cleaning work after operation stopped; Checking the debuting before start up.
1. inspection during operation:
a. measure the inlet and outlet water temperature, and current of motor. Record it well.
b. Inspection the working condition of the motor, speed reducer and driven system. Inspection the water distributing system, Inspection the fasten factor, Inspection the situation corrosion and deposition of dirt.
c. Solve the faults immediately since you realize it.(Newin Cooling Tower suggest you to spare some parts to reduce the loss caused by fault stop)
2. The cleaning work and maintenance after cooling tower stopped:
a. Water distribution system.
check the central pipe, branch water pipe, Nozzles, and confirm all parts are fasten well and not blocked. Repair fasten, and clean the pipe and nozzle in time to ensure the stable water flow and uniform spray. Clean the water basin, and filter net. avoid any scale and block of pipe. after cleaning all the parts, drain out the water basin.
b. Heat dissipation system.
Clean all the infill(PVC,PP film, or splash bar); make the surface tide and clean. If any part of infill broken and need to replace. should install tightly, and make sure no space remains. Clean the inlet louver or replace a new one.
c. Drive system
motor: inspection the motor running well or not. If any abnormal sound, please replace the bearing immediately.
Belts&pulley: adjust the bolts, loosen the belts to expand the service life of belts. Inspection the belts, see if any broken, crack, replace it if needed. proofread the levelness between pulley and motor support frame. fastening the loosen screws, replace the bolts and screws if corrosion.
Fan: Clean the fan blades surface, Measure the angle of blades, Measure the gap between blades and air stack. adjust it if necessary.
Clean the air stack, body casing, air inlet louver(nets,mesh). ensure the good appearance of tower. Inspection the body and make sure no broken, crack. and repair it necessary.
Check the auto feed system---float ball valve. Repair or replace it if needed. Fastening the tower frame and fastening factor of tower. Painting the corrosion part of steel parts. Check the flanges and make sure it not broken or crack. make sure not leakage happened.
3. Checking the debuting before start up:
Remove the cover of air stack. adjust the belts. Check carefully the drive system, motor and speed reducer. Check the cleaning of water basin. make sure no leafage of water basin. Adjust the float ball valve. adjust the angle of fan blades, measure the current of motor, and ensure it operation under perfect condition. Adjust the gate valve of inlet and outlet pipe, ensure a normal water flow.
Special note: No wedding directly on cooling tower during maintenance, to avoid any cooling tower on fire.
