How to connect the dust removal air duct and the fan?

If you want to find a buckle for the outlet pipe and the fan, you can use the buckle to snap it up, so that you can connect the two very tightly and will not loosen and can be used.

The connection between the dust removal air duct and the fan is usually a square flange plate bolted together, in this way.

It is generally very common to connect with soft connections, such as canvas connections!

The dust removal duct is connected to the fan, and it is better to use a soft connection, because this can reduce the vibration of the air duct.

How to connect the dust removal air duct and the fanThe dust removal air duct and the fan can be connected with a buckle.

The dust removal duct and the fan can be well connected together with a single joint.

The connection between the dust removal air duct and the fan is made from the air outlet of the fan.

This should have a special tube to connect, and then you can connect them through this tube.

The dust removal duct is directly connected to the fan, and there is no need for a valve in the middle.

Just like connecting to wifi, you can connect if you have a password. g

The dust removal air duct and fan must be soft grounded with canvas to prevent the fan from forming a resonance with the air duct when starting and stopping, and its length specification requirements should generally be 150-300mm; You can check GB50243-2002 to confirm.

How to connect the dustproof air duct and the fan? This one is welded, and there is a screw thread.

You can go directly through a 20A cable, and then you can make a connection directly.

How do we connect no matter the scenery? Connect it a little bit inside this setup. Pipelines are the best.

The fan and the air pipe must be connected flexibly.

Installation of the fan.

l) After the fan is selected correctly and reasonably, it is installed.

The quality is directly related to whether the fan can operate normally. The installation of the axial fan is relatively simple, whether it is mounted or hoisted, as long as you pay attention to the balance, vibration reduction and connection with the air duct of the fan. (2) The installation of centrifugal fans is relatively complicated, especially the installation of centrifugal fans driven by large belts, in addition to reasonably making vibration damping bearings, the following points should be paid attention to in installation:

The force of each shock absorber must be uniform, otherwise the noise of the fan operation will be increased;

The motor should be installed on a movable parallel slide rail in order to adjust the center surface of the pulley and the tightness of the belt;

The center surface of the motor and fan should be kept within the same axial range, otherwise the belt is easy to wear or fall off;

The belt should be tightened appropriately;

The bolts fixing the fan and motor should have anti-loosening devices; The fan and the air duct must be flexibly connected; （3）

Motor wiringIn the installation of the fan, the wiring of the motor is a problem that cannot be ignored, and the author has seen several cases of the normal operation of the fan due to the motor burning caused by the wrong wiring of the motor. The main reason is that the installers of some construction units mistakenly connect the three-phase electricity into two-phase electricity, or connect the terminals of the three-phase motor to the wrong one.

There are six binding posts on the wiring board of the motor, which can be connected to Y or Y depending on the power! The specific connection method is shown in Figure L. When the phase sequence of the power grid corresponds to the wiring mark, the motor rotates clockwise from the spindle end; If the phase sequence of the grid is changed, the switch is reversed.

The fan is connected to the air duct, and it is best to use a soft connection, which can reduce the resonance between the fan and the air duct and reduce the noise.

The surface of the air duct is opened, the axial fan is embedded, and the installation is fixed.

Are you Old Ray?

Generally, the fan manufacturer has said in the manual of the generation that it is connected with a soft connection, and in addition, the weight of the pipe cannot be pressed on the fan.

The soft joint of the canvas between the fan and the air duct canvas is connected, and the canvas soft joint between the fan and the air duct connection is generally 25 cm.

Soft joints are also called rubber pipe soft joints, rubber joints, rubber soft joints, flexible joints, high-pressure rubber joints, rubber shock absorbers and other soft joints are hollow rubber products used for flexible connection between metal pipes, this product can reduce vibration and noise, and can compensate for thermal expansion and contraction caused by temperature changes, and is widely used in various pipeline systems.

According to the connection method, the soft joints are divided into three types: loose flange type, fixed method, trouser flange type and threaded type; According to the structure, it can be divided into single sphere, double sphere, curved sphere, etc. It is composed of inner and outer layers of rubber, cord layer and steel wire ring, which are formed by vulcanization and then combined with metal flanges or parallel joint loose sleeves. This product can reduce vibration and noise, and can compensate for thermal expansion and contraction caused by temperature changes, and is widely used in various piping systems.

The principle of the fan coil unit is to achieve the previously expected cooling or heating effect by relying on the action of the fan and then relying on the operation of the surface cooler.

Fan coil units place very high demands on materials. The materials used in the manufacture of fan coil units must be of the highest quality, resulting in a very compact and durable structure that can be weld-free. At the same time, the use of excellent materials further increases the durability of the fan coil unit. Relying on the continuous circulation of the air in the room, and so that the air in the room is cooled or heated after the air passes through cold water or hot water, it is ensured.

The indoor temperature eventually does not change.

At the same time, the operation of the fan coil unit is also affected by other factors. The most important of these are air volume and water. For the fan coil unit to achieve a constant air volume, the temperature of the water supplied also needs to be constant, and when the amount of water changes, the refrigeration is required.

Quantities also change, but the impact of these changes is relatively slow. When the temperature difference between the return water and the supply of the fan coil unit remains unchanged, the larger the water temperature, the more obvious the reduction of the cooling capacity, and at the same time, the fan can be dehumidified and dried.

The force will also drop significantly. When the water supply situation is constant, the change of air volume will reduce the cooling capacity and increase the enthalpy difference. And when the water temperature difference between the air inlet and the outlet coil expands, the heat transfer coefficient of the heat exchange coil and the water.

will be less.

The soft connection length of the fan and the air duct is calculated according to 300mm (the specification specifies), the perimeter is calculated according to your actual size, (if the engineering quantity is calculated, excluding the material of the joint), the area is square meters (perimeter length).

<> fan, English: Draught Fan YWF4D-630

Fan is the customary abbreviation of gas compression and gas delivery machinery in China, and the commonly said fan includes ventilator, blower, and wind turbine.

Gas compression and gas conveying machinery is a machine that converts rotating mechanical energy into gas pressure energy and kinetic energy, and transports gas out.

The main structural components of the fan are impeller, casing, air inlet, bracket, motor, pulley, coupling, silencer, transmission parts (bearings), etc.

The soft connection between the fan and the wind tease pipe is calculated by 300mm (the specification has provisions), and the perimeter is calculated according to the actual size of your fingers, (if the engineering quantity is calculated, excluding the material of the joint), the area is square meters (perimeter length).

Measure a line with a ruler, isn't it troublesome to calculate.

Fan coil unit is the end product of the air duct machine, which is composed of heat exchanger, water pipe, filter, fan, water tray, exhaust valve, bracket, etc., and its working principle is that the air in the room is continuously recirculated in the unit, so that the air is cooled (heated) after passing through the cold water (hot water) coil, so as to keep the room temperature constant.

In terms of installation costs, the cost of an air duct is lower than that of a chiller with a fan coil unit installed. As far as supplementing fresh air is concerned, it is easier for the indoor unit of the duct to replenish fresh air than the fan coil unit. In terms of comfort, the air from the fan coil unit of the chiller is much softer and quieter.

According to the situation of the site, the general fan coil unit can be without the duct, such as the surface-mounted fan coil unit. If you need to connect the air duct, because the air pressure of the fan coil unit is relatively small, you can only connect a short section of the air duct.

Depending on the type, there are exposed fan coil units that do not need to be connected to the air duct at all, and there are also hidden ones that need to be picked up and returned to the new air duct, or part of it.

OK. That's for sure, I've been a designer before.
