3. Pressure cooker.

Steam flushing, which is a high-temperature removal method, is mainly completed by a pressure cooker, adding half a pot of cold water to the pressure cooker, boiling, and so on when the steam is constantly discharged, remove the pressure limiting valve, and align the fan blades of the exhaust fan with the steam, so that it can be flushed through high temperature.

There are many types of exhaust fans, and we need to choose the most suitable ventilation and cooling equipment according to some attributes such as air volume and static pressure. Computing Institute.

Power is required, and considering the use of the motor for this purpose, it is better to leave 20-25% of the leeway.

When two blowers are running in parallel, A becomes the sum of the air volume at the same pressure. Therefore, by plotting the respective waiting curves of FANA and FANB, the characteristic curves of parallel operation can be obtained.

Because the operating point of the blower is the intersection of the resistance curve and the characteristic curve, the air volume is large if the resistance curve cannot be found. When the resistance curve changes, the air volume basically does not increase. However, in any case, the parallel operation of the two blowers could not reach the sum of their capabilities.

Therefore, if it is really necessary to run two machines in parallel, it is necessary to redesign the thicker pipes, and the resistance curve must reach the sum of their air volumes.

Bathroom exhaust fan is the most important furniture in the bathroom area, in the use of bathroom exhaust fan, dirt or damage is possible, so you need to know how to disassemble the bathroom exhaust fan. So how to disassemble the bathroom exhaust fan? Next, let's introduce you to the bend.

1. Preliminary preparation.

Turn off the exhaust fan switch first, at this time the exhaust fan is not charged, and it will be safer to disassemble. If you are not at ease, you can pull down the electric gate of the bathroom and cut off the power of the entire bathroom. Before installation, it is also necessary to prepare the relevant disassembly work, such as screwdrivers, small blades, etc.

2. Disassemble the exhaust fan panel.

The exhaust fan panel is usually stuck on the main body, insert a knife or other items into the gap of the panel, pry the panel down, pry the exhaust fan panel out a little, and then hold the edge of the panel and pull it down to remove the panel. Some panels are fixed by spring buckles, after the panel is pried a little, it is necessary to find the position of the spring buckle, and press the spring buckle into it with your hand to take out the panel.

3. Disassemble the main body of the exhaust fan.

After the panel is removed, you can see the fixing screws around the exhaust fan body, and you can loosen the fixing screws with a screwdriver, and tilt it to bury it in the quiet exhaust fan body. After the main body of the exhaust fan is pulled out, you can see the ventilation duct connected to the bucket vent behind the main engine, and tear the aluminum foil tape at the connection of the ventilation duct to separate the ventilation duct from the main engine vent. Finally, remove the power cord on the host drive, and the removed power cord connector should be wrapped with electrical tape.

The installation method of the exhaust fan is as follows:

1. The installation is stable, and the horizontal orientation of the fan should be paid attention to when installing the kitchen ventilation fan.

2. Adjust the fan to be consistent with the level of the foundation plane, and there can be no skewed appearance after the ventilation fan is installed.

3. When installing the kitchen ventilation fan, the adjusting bolt of the motor should be arranged in a convenient position to facilitate the operation, so that the belt tightness of the ventilation fan can be adjusted when using.

The exhaust fan is a kind of air conditioning appliance that is driven by an electric motor to rotate the fan blades to drive the airflow and make the indoor and outdoor air exchange, also known as ventilation fans. The purpose of exhaust air is to remove dirty air from the room and regulate the temperature, humidity and feel. So, here's the problem.

I believe that many people do not know how to install the exhaust fan, and after listening to the introduction below, you can try to install the exhaust fan yourself. The following is an introduction to how to install the exhaust fan.

1. Before the installation of the exhaust fan, we must check the exhaust fan to see if the product is intact or undamaged, whether the fasteners and bolts of the exhaust fan are loose or falling, and whether the impeller of the exhaust fan is non-bumping, and then carefully find out whether the fan blades or louvers are deformed or damaged during transportation. If there is some damage, you must find a manufacturer to replace it.

2. The installation of the exhaust fan should be stable: when installing the exhaust fan, attention should be paid to the horizontal orientation of the fan, and the level of the fan should be adjusted to be consistent with the level of the foundation level. The exhaust fan must not appear skewed after installation.

3. When installing the exhaust fan, the conditioning bolt of the motor should be in a convenient position. In order to adjust the tension of the ventilation fan belt when using.

4. To install the exhaust fan bracket, be sure to make the bracket consistent with the foundation plane, and install an angle iron next to the ventilation fan for reinforcing if necessary.

5. After the exhaust fan is installed, the sealing around it should be checked. If there is open space, it can be sealed with a sun panel or glass glue.

6. After the installation is completed, check whether there are any things and debris left inside the exhaust fan. Move the fan blade with your hand or lever to see if it is too tight or rubbing the appearance, and if there is no abnormal appearance of the item that hinders the transformation, you can carry out the trial work.

7. If there is an abnormal movement of the exhaust fan oscillation or "buzzing" of the motor or other abnormal appearances during work, it should be stopped for inspection, and then started after correction.

The installation method of the exhaust fan is as follows:

Tools Material: exhaust fan BPT12-13C, screwdriver, pliers, electrical tape.

1. First of all, prepare the exhaust fan to be installed, remove the cover of the installation place with a screwdriver, and measure the size of the installation.

2. After the size is adjusted, you need to remove the exhaust fan and clean up some unwanted things inside.

3. After everything is cleaned, connect the pipes of the exhaust fan together, and fix them with glue or adhesive tape. The interface is fixed with screws.

4. After that, you only need to install the exhaust fan on the ceiling and fix it with screws.

Pay attention to the precautions for the installation of exhaust fans

1. When installing the exhaust fan, it should be as close as possible to the original air duct outlet, and it should be installed in accordance with the principle of the shortest pipeline. When installing the exhaust fan, it should be as close as possible to the location where the smell is humid to achieve the best exhaust ventilation effect. For the exhaust fan in the bathroom, it is not advisable to install it directly above the shower, because the airflow generated by the exhaust fan during exhaust ventilation will cause discomfort to the human body.

2. Check whether the fan, firmware bolts, impeller, and blade fan are damaged, loose or deformed before installation. The ventilation fan must be installed on a solid wall, at a distance from the ground. There should not be too many obstructions in the air outlet.

Adjust the level between the fan and the foundation plane so that the adjusting bolt of the motor is in a position that is convenient for operation.

3. Finally, the fan bracket must be horizontally stable with the foundation plane, and if necessary, install an angle iron next to the fan for re-reinforcement. As well as the power supply of the exhaust fan, try to connect the omnipolar switch.
