High pressure fan installation precautions

High pressure fan installation precautions:

High-pressure fan use precautions;

I. Precautions for start-up preparation and start-up Before start-up, the following inspections and confirmations must be performed. When commissioning is performed after installation and alignment, attention should be paid to the following matters and be handled with care.

1. Check if the specifications of the fan and prime mover meet the requirements of the order.

2. Check whether the power supply (voltage, switch, etc.) and the line meet the electrical requirements. Whether the wiring is accurate.

3. Check whether there are condensation water, dust and other sundries in the fan and pipeline. If yes. You need to clear the net and switch off the fan to start a major failure.

4. Check if the anchor bolt, fan body, attachments and attachments, connecting part of the connection pipe are tightened as required.

5, confirm whether the parts are correct. For coupling or belt driven fans. To check the coupling or pulley. V-belt installation is reliable. Concentricity of the fan shaft and the motor shaft is awkward.

6, check the night bearing grease "fat" is sufficient, intact. If there is an oil supply device, try the test for 2h. Is the side oil temperature and oil pressure normal?

7. For fans with water-cooled bearings, check that the water supply to the cooling water line is normal.

8. Manually rotate the fan shaft and prime mover shaft. Check that the rotation is smooth. Confirm that there is no abnormality.

9. Turn the prime mover separately. Make sure that the direction of rotation of the prime mover is consistent with that of the fan. At the same time, confirm that there is no abnormality on the prime mover side.

10. For belt driven fans, check whether the tension of each V-belt is the same at night.

11. When using a coupling that requires lubrication, check that the injected lubricant is acceptable.

12. Check whether the regulating door or valve is fully opened or closed and whether there is abnormal operation. Fan's inlet and outlet regulating doors. Centrifugal is fully closed. When the axial flow is fully open, the starting load is minimal.

13, for the fan with bearing strong side oil supply device. Should confirm the fuel tank, the fuel tank and the oil pipeline is clear, the direction of rotation of the oil pump, the oil cooler water supply and drainage agencies and chain institutions are normal.

14. In addition, the relevant operators should be provided with necessary training in advance so that they can do the following: When the fans begin to operate suddenly, they can quickly make the correct actions according to the instruction of the operation commander.

Always check the position of each valve before operating the high pressure fan:

First, daily operation Note Roots fan air inlet regularly cleaned, its oil level, pass

Check the moving parts.

2. Check whether the Roots Blower oil level is normal before and during operation of the blower.

Third, the hot weather should pay attention to the air circulation in the blower room, timely open the windows or exhaust fans

Fourth, the blower starts and stops to open the valve, start and stop without load. After starting the valve is closed to see the pressure gauge slowly close the pressure is strictly prohibited to exceed 0.63kg \ c operation.

5. It is forbidden to change the frequency value set by the inverter without authorization (42HZ

6. It is forbidden to overload the operation of the blower during operation.

Current control operates below 57.6A. No abnormal fluctuations.

7. Is it correct? The three-phase voltage is balanced (380-400) volts.
