blowerWidely used for ventilation, dust removal, and cooling in factories, mines, tunnels, cooling towers, vehicles, ships, and buildings; Ventilation and induced draft for boilers and industrial furnaces; Cooling and ventilation in air conditioning equipment and household appliances; Drying and selection of grains; The inflation and propulsion of wind tunnel sources and hovercraft, as well as various equipment for environmental protection, medical, electronics and other industries.blowerIt has the characteristics of reasonable structure, small size, high efficiency, light weight, large flow rate, low noise, energy saving, smooth operation, long service life, and easy maintenance. It has been widely used in industries such as sewage treatment, cement transportation, pneumatic conveying, mining, chemical industry, smelting, building materials, electricity, flour, vacuum packaging, and aquaculture.
The operating environment of the blower should be kept clean and tidy regularly. Lubricating grease should be added or replaced irregularly according to the operating environment conditions (motor enclosed bearings do not need to be replaced with lubricating grease during their service life). To ensure good lubrication of the blower during operation, the oiling frequency should not be less than 1000 hours per time for the enclosed bearings and motor bearings. ZL-3 lithium based lubricating grease should be used to fill 1/3 of the inner and outer rings of the bearings during oiling. Oil deficient operation is strictly prohibited. The surface of the blower should be kept clean, and there should be no debris at the inlet and outlet. Regularly remove dust and other debris from the blower and pipeline. It can only operate under normal conditions of the blower. Colleagues should ensure that the power supply facilities have sufficient capacity and stable voltage. It is strictly prohibited to operate without phase. The power supply line must be a line and temporary lines should not be used for long-term power supply.blowerDuring operation, if abnormal noise is found in the fan, the blower is severely overheating, the shell is electrified, the switch trips, and cannot be started, the machine should be stopped immediately for inspection. To ensure safety, maintenance is not allowed during the operation of the blower. After maintenance, a trial run should be conducted for about five minutes to confirm that there are no abnormal phenomena before starting the machine. The blower should be stored in a dry environment to prevent the motor from getting damp. When the blower is stored outdoors, there should be defensive measures. During storage and handling, the fan should be protected from collision to prevent damage.
Characteristics of blower:
(1) The blower may generate high temperatures during use, so avoid touching the casing to prevent burns.
(2) The motor load current will vary with the air pressure used by the blower. When wiring, an overload protection switch suitable for the model should be installed and used at the rated full load current to avoid motor burnout.
(3) Please refer to the air volume static pressure curve chart in the catalog for the applicable range of continuous operation of the blower, and use it within the curve range without exceeding the applicable range. If it is necessary to approach the closed pressure when using, a pressure relief valve should be installed in the pipeline. When the pipeline is closed, the pressure relief valve will automatically open to regulate the air inlet and outlet to ensure the service life of the blower. If the blower is operated under the closed pipeline, the temperature will rise sharply. At this time, continuous operation should be avoided, otherwise deformation or damage may occur. When the air used is intermittent, use the air valve switching mode to operate.
(4) Hard objects, dust bags, powder particles, fibers, and water droplets should enter the fanblowerBefore removal, dust collection bags can be used for disposal. If a filter is installed in the pipeline, to avoid pressure loss, please use a large-area filter and regularly clean the pollutants in the filter.
(5) Regularly clean the inside and outside of the blower to remove surface dust. If a large amount of dust accumulates, the heat dissipation effect will deteriorate, which may cause temperature rise, reduced air volume, increased vibration, and ultimately lead to malfunction.
(6) Bearings, oil seals, and mufflers are consumables and therefore have a certain lifespan, requiring regular replacement. At the same time, blades, shells, metal mesh, etc. must also be replaced regularly according to the usage environment (mainly corrosive air flow, gas-liquid mixture, etc.).
(7) If the operation is not smooth or there is abnormal noise during use, please turn off the power for maintenance or call Huaguan blower for support.
Static pressure is the force exerted by a fluid on the surface of an appliance and perpendicular to the surface. In a fan, it is generally caused by gravity and the push of the fan,blowerIt is often expressed in kgf/m2 or mmaq and can be directly measured. In the air duct of a fan, the static pressure value in any direction is constant and can be positive or negative. If the static pressure value is regular, it indicates that the air duct is currently being inflated, and if the static pressure value is negative, it indicates that the air duct is currently being compressed.
If used for air delivery in water,blowerThe water depth should be below 70% of the maximum static pressure value indicated on the catalog. When using pressurized air delivery, it is normal for the outlet temperature to be higher than room temperature by more than 10 ℃ due to air compression, so an iron pipe of at least 1M should be used. The suction outlet can be equipped with a muffler. The total cross-sectional area of the suction hole should be greater thanblowerHalf of the entrance cross-sectional area.
