U.S. Ultrium positive and negative pressure fan instructions

U.S. Ultland positive and negative pressure fan

First, the structure of positive and negative pressure fan of U.S. Ultrium is shown in the figure.

Fan adjustment bolts, motors, U -belts, fan pages, ball bearings, shutters, protective nets, heavy hammers and other accessories.

Second, the United States Uranty positive and negative pressure fan daily maintenance

( 1 ) Clean up the impurities of the protective net,

( 2 ) Check the looseness of the belt. If any looseness is found, arrange the adjustment and reset immediately.

( 3 ) Whether the bearing of the motor has abnormal noise or not, if there is any check for the presence of lubricant on the motor!

III. Maintenance and Maintenance of U.S. Ultland Positive and Negative Pressure Blowers

( 1 ) First disconnect the power supply of the host and check if the ground wire is grounded properly:

( 2 ) Check whether the screws and couplings of each part are fastened

( 3 ) Check the instructions to check whether the insulation resistance of the motor meets the requirements and check the main circuit contacts. If the contacts are severely abraded or the wear is severe, replace the contacts immediately.

Fourth, the maintenance of the valve

(1) adjusting the tightness of the belt, manual rotation of the wind wheel, a smooth rotation is observed.

( 2 ) Inspect and replace gaskets and seal packings between joint surfaces.

( 3 ) Clean the motor rotor, filter and the inside of the housing. In order to prevent the rust from peeling off the part of the paint, it should be repaired in time.

( 4 ) In order to ensure the flexibility and stability of the coupling and bearing, lubricate the rotating parts.

Fifth, for the maintenance of electrical circuits

( 1 ) Whether the valve is mechanically opened and closed is flexible and reliable, and whether the opening/closing angle flag is clearly visible.

( 2 ) The indicator light, voltmeter, and ammeter are all normal. Each fan operating member there is no abnormal sound, three-phase current value is balanced. Check if the components inside the remote control box are all normal.

( 3 ) Perform continuous on/off operation and check whether the remote control of each point is correct and reliable.

( 4 ) Test run for two hours , observe whether the motor bearing temperature and motor temperature rise within the normal range

Sixth, the United States You Lanter positive and negative pressure fan installation and use

First, unpack and inspect whether the various parts of positive and negative pressure fans are deformed or damaged during transportation. If this is the case, they should be installed and used after they are corrected.

( 1 ) Open the junction box and turn on the power supply to run (no load). The rotation direction of the impeller is the same as that of the nameplate. The fan casing of the positive and negative pressure should be grounded and observe whether it touches the shell. If this happens, adjust it immediately. .

( 2 ) The positive and negative pressure fans are installed in place and all fasteners must be tightened again.

( 3 ) After the positive and negative pressure fan inlet and outlet pipes to be removed and all obstacles in the vicinity are put back, they can be put into use.

Seventh, U.S.Ultimate pressure fan use environment

( 1 ) The use environment should always be kept clean, the surface of the fan should be kept clean, and there should be no debris in the inlet and outlet. Remove dust and other debris from fans and pipes regularly.

( 2 ) It can only be operated under the condition that the fan is completely normal. It is necessary to maintain adequate capacity of the power supply facilities and the voltage is stable. The lack of phase operation is strictly prohibited. The power supply line must be a dedicated line and should not be powered by temporary lines for a long time.

( 3 ) During the operation of the fan, it is found that the fan has abnormal sound, the motor is seriously heated, the shell is energized, the switch is tripped, and cannot be started. The machine should be shut down immediately for inspection. In order to ensure safety, it is not allowed to perform maintenance during the operation of the fan. After the inspection and repair, the test run shall be performed for about five minutes to confirm that there is no abnormal phenomenon and then start the operation.

( 4 ) According to the use of environmental conditions from time to time to supplement or replace the bearing grease (motor closed bearing does not have to replace the grease during the service life), in order to ensure the good lubrication of the fan during operation, refueling frequency of not less than 1000 hours / Times, closed bearings and motor bearings, refueling fill 2/3 of the inner and outer rings of the bearing with ZL - 3 lithium grease . It is forbidden to run without oil.

( 5 ) Fans should be stored in a dry environment to prevent the motor from getting wet. When the fan is stored in the open air, there should be rainproof measures. In the process of storage and handling, the fan should be prevented from bumping so as not to damage the fan.
