Nowadays, with the development of the economy, with the advancement of technology, we have invented a variety of fans. Therefore, when we purchase, we need to choose according to their own requirements. For example, in order to ensure the circulation of air in the cabin, we use the marine fan. Let’s take a detailed understanding of the "Introduction to the installation process of the marine fan and its related information".
[Basic common sense of marine fan]
The ship fan is composed of a single-clad bending inclined centrifugal impeller, muffler case, low noise fan special motor. The adjustment door of the marine fan is used to regulate the size of the fan flow. It consists of 13 pieces of flowered blades, and is axially mounted in front of the ventilation. Since the structure of external transmission is used, the rotation is flexible and convenient. The adjustment range is 90 ° (completely closed) to 0 ° (all open).
Adjust the door of the door, look from the direction of the air, on the right. For the right vane, the pull-up is pushed up to the top to the full open direction; for the left-turn fan, the wrench is pulled by the top to the full open direction.
The marine fan has the characteristics of high efficiency, low noise, high static pressure, simple structure, beautiful appearance, convenient installation and maintenance. The marine fan can deliver air, containing sea-free air with salt mist and a small amount of acid vapor formed by oil mist, battery natural evaporation, and the ship fan is suitable for ventilation gas ventilation, boiler ventilation, or boiler. Suitable for other suitable occasions.
The marine fan changes the flow direction of the medium in the exhaust. Marine fans are often mounted in air conditioning units, exit, boiler drums, air machines and other places. The marine fan is the mechanical energy that relies on the input mechanical energy, improving gas pressure, and the gas is used, which is a substantially fluid machine.
Centrifugal winds are widely used in factory, mines, tunnels, cooling towers, vehicles, ships, and buildings; ventilation and ventilation in boilers and industrial furnaces; cooling and cooling in air regulation equipment and household appliances Ventilation; drying and delivery of cereals; wind tunneling and inflatable and advancement of hovercraft. The working principle of the fan is basically the same as the turbine compressor, but since the gas flow rate is low, the pressure varies is not large, and the gas specificity is not required, that is, the gas is treated as a non-compressible fluid.
The centrifugal fan classification can be divided into centrifugal, axial flow, slope, and horizontal flow. The fan is divided into a shaft fan, centrifugal fan and a slope (mixed flow) fan according to the air flow.
The fan is divided into a press-in partial fan (hereinafter referred to as the press-in fan) and the vertical operation of the electric motor or in the flow path, the explosion-proof motor is placed in an explosion-proof seal chamber (hereinafter referred to as extracting fan .
Instructions for marine fans
1. Check whether the door is fine;
2. Check if the operating gap between the parts is within the specified range, the rotating part is uniform and friction, the fastener connection is intact, and the equipment pipe has no seal; the wind turbine is turned off;
3. Check if the lubrication is lubricating oil, whether it is appropriate;
4. Press the "Start" button to turn on the power to start the high-pressure centrifugal fan;
5. Xu Xu Qijin to the desired size, strictly monitor fan vibration and sound, and find abnormal parking;
6. Strictly monitor the fan running current during operation, and the current is too much to adjust the load to reduce the amount of current. If the current cannot solve the current excessive phenomenon, the wind turbine drive system must be completely inspected;
.
[Marine fan installation process]
The marine fan is equivalent to air conditioning on board, bypass design, energy saving.
Inside the device, the bypass system is added. When the transition season or outdoor air is compared with the indoor air, it utilizes the bypass function to make full use of nature free resources. The service life of the unit has reached energy saving, and the ship wind turbine disk tube heat The thermostat is made of a thin-walled purple copper tube and an aluminum fins. It is used to strengthen heat transfer with a low noise fan in a large fan, so that the unit can play the thermal transmission efficiency of ZUI ideal. Pieces of water use brass forge To make the flow distribution uniform and reduce the losses of the head, further improve the entire heat transfer effect of the coil.
The bearing used by the motor is a ball bearing. The motor shaft uses tuning steel, the surface is specially treated, the maintenance and maintenance cost is low. Optional button three-speed switch, easy to operate, can adjust the inner air volume and coldness. Units and optional detachable air filters.
Marine fan installation:
1. Familiar with the sample of the fan, familiar with the specifications of the fan, type, impeller rotation direction and airflow inlet and outgoing direction; before the ship fan is installed, the impeller has no raw touch phenomenon, and the various components are fully inspected, the accessories are intact, Whether the components are jointly fastened. Seriously check whether the blanks are damaged due to transport damage or deformation, otherwise it should be installed.
2, the air tube of the joint ship fan import and export should have a separate support, which is not allowed to be added to the part of the fan; the fan is installed, the horizontal position of the fan, the joint surface of the fan and foundation and the air supply pipe The coupling should be adjusted, which makes it naturally, and must not be forced to join.
3. After the marine fan is installed, the impeller is pulled by hand or lever, check whether there is too tight or rubbing the phenomenon, there is no abnormal item, and there is no abnormal phenomenon, and the trial operation can be made.
The exposed part of the marine fan transmission should have a protective cover (user self-contained), such as when the wind is venting, it is also necessary to add a protective net or other security device (user self-preparation).
4, the marine fan wiring must be correct and reliable, the wind turbine housing should be properly grounded, the ground must be reliable. The power supply to the fan must be complete and meet the relevant requirements. The fan wiring must have an electric wiring of expertise.
5. All the tools and debriss inside the fan should be checked after all the marine fans are installed.
The fan is an air energy recovery ventilation device. The core function is to use the indoor, outer air, and through the thermal moisturemous and moisture permeability of the full heat recovery core, the marine fan is exchanged in two-way displacement air, The new wind effectively obtains energy in the exhaust, thereby greatly saving the energy consumption of new wind pretreatment, achieving energy-saving ventilation, which saves energy, including thermal and latent heat, very significant energy efficiency, heat exchange efficiency ZUI high More than 75%.
The marine fan can effectively recover the energy lost in the indoor exhaust, and ZUI will save energy, the operation is inhaled, and the exhaust is very comfortable. The full heat exchange new marine fan is mostly used to secure the widening structure heat exchange core, from the new wind introduced from the outdoor, flow through the heat exchange core, but it is not directly in direct contact with each other; After specially designed hexagonal full heat exchange core, it can recover the heat, and can effectively recover moisture.
The above introduction to the "Basic Common Sense of Marine Fan" and "Marine Fan Installation Process", I hope to let you know the "introduction of the installation process of the marine fan and its related information".
