Safe operation guarantee 6 cooling tower safety operation procedures:
1. Purpose: In order to use the cooling tower more safely, this regulation is formulated.
2. Scope of application: suitable for the operation of cooling towers.
3. Contents:
3. 1 installation
A. During hoisting and installation, ensure that the equipment will not be damaged.
B the vertical axis of the cooling tower shall be ensured during installation, and the tower body shall be stable and reliable.
C. the water inlet and outlet pipes are unobstructed. The pipe diameter used should match the design water quantity of the cooling tower.
D before normal operation after installation and debugging, the circulating system should be replaced with clean water twice. Discharge rust water and sewage, ensure the normal use of the whole circulation system equipment and prolong the service life.
3.2 Check before starting operation
A. Clean the air inlet and outlet of the cooling tower and the foreign bodies in the bottom basin, rinse the bottom basin with clean water, and then discharge it from the sewage pipe.
B. Turn the metering system slowly with your fingers, and adjust the outlet angle of the metering tube (the angle between the outlet angle and the vertical plane is 15 degrees) to ensure the smooth and flexible operation of the metering tube.
C. Start the water pump intermittently to remove the air in the pipeline until the pipeline and chassis are filled with water.
D. Check whether there is enough clearance between the end of the fan and the inner wall of the ram. The clearance should be uniform and the angle of the fan blades should be consistent to avoid damage during operation.
E. Check whether the circuit is normal, and confirm whether the specifications of the circuit switch, safety device and wiring conform to the specifications of the motor, so as to avoid single operation and avoid burning the motor.
F. Check whether the running parts rotate flexibly, and solve the problems in time if found, so as to avoid serious consequences.
3.3 Start and run
A. Start the motor and fan when the empty tower is running at no load (without adding water), and check whether the motor and fan are running normally. At this time, the fan should rotate clockwise (looking down), and the no-load running time should not exceed 10- 15 minutes. After normal operation, turn off the motor.
B. Open the water inlet valve, spray water, check whether the spray pipe rotates normally, whether the water distribution is uniform, and whether the water inlet and outlet are unblocked. Adjust the float valve to make the water level reach a proper position, and control the water level in the bottom basin to ensure that there is no "evacuation" phenomenon. The rotation direction of the seeding tube should be clockwise (top view).
C. detect the actual current value of the motor, which cannot be greater than the rated current value of the motor. High-power motors should be equipped with overload protection devices.
D normal operating procedure: when the cooling tower is running, start the water pump first, and then start the motor. 3.4 downtime
A normal operating procedure: when the cooling tower stops, turn off the fan first, and then turn off the water pump.
3.5 Maintenance and maintenance
A. To keep the tower clean, clean the inside of the tower, open the sewage outlet and drain until there is no residue.
B. Check whether the bolt is loose, whether the belt is tight and tighten it in time.
Guarantee for safe operation 7 1. Employees must wear labor protection articles correctly, lesbians should have curly hair, and it is strictly forbidden to go to work sick or drunk.
2. The personnel on duty should be familiar with the working principle, technological process, operating procedures and operating parameters of this part of the equipment.
3. When the packing layer and nozzle are blocked by scale and sludge, it must be confirmed that the switch has been cut off and listed before cleaning.
4. When the cooling water temperature at the outlet of the cooling tower exceeds 50℃, it shall be stopped immediately for inspection and treatment.
5. The water in the cooling water tank of the cooling tower should be completely replaced every 2 months of operation or when the kiln is stopped for maintenance, and the water tank should be cleaned to prevent the cooling water from concentrating due to the long-term operation of the cooling tower, so as to prevent the cooling part of the cooling tower and equipment from corrosion and scaling.
6. Before running the fan, please carefully check whether there are any foreign objects inside the cooling tower and on the fan blades. If the blades can be moved flexibly by hand (especially after the fan is overhauled and snowed), if this happens, they need to be removed and the lubricating oil level should be confirmed to be above the normal oil level before starting. During the operation of the fan, personnel are prohibited from entering the cooling tower.
7 When the reducer or motor is found to have abnormal vibration or sound during operation, it should be stopped immediately for inspection and treatment, and normal operation can be started only after the trial operation is normal.
8. In the process of operation, if the oil level is abnormally low, and the oil level gauge takes into account the oil leakage in the pipeline and the oil level drops abnormally, it should immediately stop the machine for inspection and handling.
9. Before starting the cooling water pump, confirm the water level in the cold water tank, the open and close state of the import and export valves, and open the exhaust hole at the upper part of the pump for exhaust. Only after completing the above procedures can the cooling water pump be started.
10. During the operation of the cooling water pump, closely monitor the water leakage at the root of the front and rear axle disks, the vibration of the unit and the outlet pressure. If there is any abnormality, you should contact all professionals to stop the machine (it can be switched when running alone) for inspection and handling;
