How to use a high pressure fan? What are the uses of high pressure fans?

High air pressure is a fan with a certain pressure and flow, this kind of fan is very different from ordinary fans, this kind of fan is mainly through the increase of pressure to achieve the function of blowing or suction, but also to achieve suction and blowing at the same time. Different functions are used in different productions.

The suction of high-pressure fans is generally used in industrial vacuuming, vacuum dehydration and textile machines, which can play a good role. Of course, this equipment can also be used in powder vacuum conveying, and the powder is transported directly with this equipment in transportation, which can shorten the transportation time, and direct transportation with equipment can avoid waste.

The blowing function of the high-pressure fan can be used in bottle washing machine drying, sewage treatment, car washing and drying, paper cutter and so on. Especially in the car wash blow drying is extremely widely used, in the process of car washing, the use of this equipment to blow dry the vehicle, can shorten the working time, improve the speed of car washing.

The suction and blowing function of high-pressure fans is the most widely used, mainly used in folding machines.

In ordinary use, the high-pressure fan is used in a reasonable place, so that the equipment can bring great help to people's life and production. In addition, when using the equipment, it is necessary to pay attention to the product characteristics of the high-pressure fan, and give full play to its advantages, so that the equipment can contribute to people's use.

The high-pressure fan can be used as a gas supply source, connected to a mask through a pressure reducer and long pipe, to provide breathable air for people working in toxic and harmful gases.

The high-pressure fan is mainly used for atomization dryers, water treatment blasts, aquaculture, screen printing machines, photographic plate making machines, and injection molding machines.

Material dryer, liquid filling machine, powder filling machine, paper cutter, combustion deaeration machine, cigarette filter forming machine, electroplating tank liquid stirring, electricity.

Welding equipment, paper transport, cleaning purposes, air de-tipping, bottle drying, gas transfer, feeding, collection, etc.

Under the design conditions, the fan with an air pressure of 30kpa, 200kpa or a compression ratio of e= belongs to the category of high-pressure fan, and the current industry generally classifies the air ring vacuum pump as a high-pressure fan. High-pressure fans, also called high-pressure blowers, are different from general centrifugal high-pressure blowers.

How high-pressure fans work::

When the impeller 3 rotates, due to the effect of centrifugal force, the weather vane promotes the gas to move forward and outward, thereby forming a series of spiral movements. The air between the impeller blades rotates in a spiral shape and the gas outside the pump body is squeezed into the side groove (sucked in by the suction port 1), and when it enters the side channel 2, the gas is compressed, and then returns to the impeller blades and rotates again at an accelerated pace. As the air passes through the impeller and side grooves along a spiral track, each impeller blade increases the degree of compression and acceleration, and as the rotation progresses, the kinetic energy of the gas increases, causing the pressure of the gas to pass along the side channel to increase further.

When air reaches the connection point of side groove and discharge flange (side channel narrows at outlet), gas is extruded out of the vane and discharges out of the pump body through outlet muffler 4.

1. Preparations before starting.

1. Check whether the connecting bolts are firm, whether the cooling water is normal, and the lubrication of the high-pressure fan bearings should meet the requirements.

2. The instruments are complete and accurate, the electric actuator is flexible, and the damper is in the closed position.

3. Whether there is a stuck axle, friction and collision phenomenon in the three turns of the manual winding car.

4. The transfer switch on the fan control box is in the "0" position.

5. The grounding switch of the high-voltage switchgear is in the "open" position.

6. Notify the substation to send the control power supply, and after the energy storage mechanism is energy storage, the energy storage indicator light will be on, and the words "energy storage" can be seen in the observation window.

7. Notify the substation to send high-voltage electricity (the electrician is responsible).

2. Turn on the machine 1 Open the control box, turn the transfer switch to the "local" position, press the start button, and the high-pressure fan starts to run.

2. During the start of the fan, pay attention to the changes in voltage, current and abnormal sound.

3. After the high-pressure fan is running normally, check the fan sound, bearing temperature, cooling water flow, motor temperature rise and fan vibration, and deal with any abnormal situation in time.

4 Slowly adjust the damper to the desired position.

5.During the operation of the fan, it is necessary to pay attention to the changes in current and voltage at all times, and it is strictly forbidden to overload the operation.

6.The surface temperature of the bearing shall not be higher than 75 during the operation of the fan, and the temperature rise shall not exceed 40.

3. Normal shutdown.

1 Close the damper.

2 Make sure the rotation button is in the "local" position, press the "Stop" button, and then turn the rotation button to the "0" position.

3 Turn off the power (electrician is responsible).

4. Emergency Shutdown:

1. Once an emergency abnormality is found, rotate the control box button to the "local" position on the spot, press the "stop" button, and then turn it to the "0" position to prevent restart after the call.

2 Close the damper.

3 Turn off the power (electrician is responsible).

5. Clean up the site and make original records.

Information**.

It is true that some of the problems that arise when the high-pressure fan is working are caused by the wrong installation. As a high-pressure fan technician, I will answer "What problems should be paid attention to when installing high-pressure fans": 1. Check the inside of the casing and other shells to prevent the remnants of tools or sundries; 2. The fan and the air duct are connected by a hose (flexible material and non-combusting), the length should not be less than 200mm, and the pipe diameter should be the same as the size of the inlet and outlet of the fan.

In order to ensure that the hose does not appear twisted and deformed during the operation of the system, it should be installed with appropriate tightness. For the canvas hose installed at the suction end of the fan, it can be installed slightly tighter to prevent the fan from being sucked in during operation and reduce the cross-sectional size of the canvas hose; 3. Ensure the horizontal position of the spindle, and measure the concentricity of the spindle on the motor shaft and the non-parallelism of the two end faces of the coupling. The uniformity of the non-parallelism of the two axes is, and the uniformity of the non-parallelism of the two ends of the two-axis device is; Fourth, the steel bracket of the fan must be fixed on the concrete foundation, and the rubber damping pad must be added between the steel bracket and the foundation of the fan.

All fan and motor components are installed on the whole steel support, and the steel ground frame is installed on the vibration damping pad at the top of the foundation, and the vibration damping pad is best made of porous rubber plate; 5. The pipe diameter of the fan outlet can only be larger, not smaller, and finally the air outlet should be installed with insect proof, and the wind and rain cap must be added when the wind is biased upward; After installation, try to dial the transmission group to check whether it is too tight or collides with the fixed part. If something is wrong, it must be corrected. If you need to know more:

The working principle of the high-pressure fan: The impeller of the high-pressure fan is composed of dozens of blades, which is similar to the impeller of a huge gas turbine. The air in the middle of the impeller blades is subjected to centrifugal force and moves towards the edge of the impeller, where the air enters the circular cavity of the pump body and recirculates in the same way from the beginning of the blades.

The circulating air flow created by the rotation of the impeller leaves the air pump for use with extremely high energy. The Teakor high-pressure fan is very good, an American brand, and the performance is also OK. It adopts a special motor, which is compact in structure, small in size, light in weight, low in noise, and the air source is waterless and oil-free.
