    Overview of high pressure fan:

    High pressure fan refers to a fan with a wind pressure of 30kPa ~ 200KPa or a compression ratio e = 1.3 ~ 3 under the design conditions. In the current industry, air ring vacuum pumps are generally classified as high pressure fans. High pressure fan, also called high pressure blower, is different from general centrifugal fans .

    Working principle of high pressure fan:

    When the impeller rotates, the vane causes the gas to move forward and outward due to the centrifugal force, thereby forming a series of spiral motions. The air between the blades of the impeller accelerates in a spiral shape and squeezes the gas outside the pump body (inhaled through the suction port) into the side groove. When it enters the side channel, the gas is compressed and then returns to the space between the blades of the impeller again. Speed up rotation. When the air passes through the impeller and the side groove along a spiral track, each impeller blade increases the degree of compression and acceleration. As the rotation progresses, the kinetic energy of the gas increases, so that the pressure of the gas passing along the side channel further increases. When the air reaches the connection point between the side groove and the discharge flange, the gas is squeezed out of the blade and discharged out of the pump body through the outlet muffler.

    Installation method of high pressure fan:

    1. When installing a high-pressure fan, it is necessary to use a flat washer and another spring washer, so that the screws can be tightened without loosening;

    2. Pay attention to the selected installation materials. It is best to use rubber and buffer rubber for installation. It can bear the weight of the high-pressure fan. After the installation of the equipment is completed, no problems will occur in later use. Especially for some devices with relatively high power, it is even more necessary to choose these two types of adhesives.

    3. In order to avoid noise from the high-pressure fan during operation, a silencer can be installed on the equipment to meet the needs of use. Even if the equipment is running, it will not affect people's lives.

    4. Silencer cotton can also be installed on the high-pressure fan, which can also reduce noise. For the installation of sound-absorbing cotton, you can directly consult with our company without knowing it.

    5. In order to isolate the vibration, hoses can be connected to the pipes of the inlet and outlet of the high-pressure fan.

    Daily maintenance and maintenance of high pressure fans:

    1. The use environment of the high-pressure fan should always be kept clean and tidy, the surface of the high-pressure fan should be kept clean, and there should be no debris at the air inlet and outlet. Regularly remove the dust and other debris in the fan and pipes.

    2. It can only be operated under the normal condition of the high-pressure fan. Colleagues must ensure that the power supply facilities have sufficient capacity and stable voltage. Phase-loss 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 high-pressure fan, abnormal sounds of the fan, severe heating of the high-pressure fan, electrification of the casing, tripping of the switch, and inability to start should be found, and the machine should be shut down immediately for inspection. In order to ensure safety, maintenance is not allowed during the operation of the high-pressure fan. After the maintenance, a trial run should be performed for about five minutes to confirm that there is no abnormal phenomenon and then restart the operation.

    4. The high-pressure fan should be stored in a dry environment to prevent the motor from getting wet. When high-pressure fans are stored in the open air, there should be defensive measures. Fans should be prevented from bumping during storage and handling to avoid damage to the fans.

    5. According to the use of environmental conditions, the bearings are replenished or replaced from time to time (the motor closed bearings do not need to be replaced during the service life). In order to ensure good lubrication of the high-pressure fan during operation, the number of refueling times is not less than 1,000 hours For closed bearings and motor bearings, fill the 1/3 of the inner and outer rings of the bearing with zl-3 lithium-based lubricating oil. It is strictly forbidden to run without oil.
