Ventilation principle
During the process of exhaust fan expelling air outward, it will cause a decrease in indoor air pressure, resulting in a thinning of indoor air and the formation of a negative pressure zone. The air will flow into the room due to the pressure difference compensation. In practical applications of industrial plants, exhaust fans are usually installed centrally on one side of the plant, with the air inlet on the other side of the plant. Air flows through the air inlet to the exhaust fan to form a convective blow. During this process, the doors and windows near the exhaust fan remain closed, forcing air to flow into the workshop through the compensating doors and windows on the intake side. The air flows into the workshop in an orderly manner through the air intake, passes through the workshop, and is expelled from the workshop by the exhaust fan. Thorough and efficient ventilation, with a ventilation rate of up to 99%. Through specific engineering design and the design of ventilation rates and wind speeds as needed, any high heat, harmful gases, dust or smoke can be quickly discharged from the workshop, and any ventilation problems can be completely solved in one go. The ventilation effect can be achieved within a few seconds of turning on the fan.
Cooling principle
The exhaust fan can quickly exhaust the hot and humid indoor air, and suck the air from the other side of the outside into the room to reach a temperature that is equal to the outside temperature, so as not to raise the temperature inside the workshop. During the process of air flow, it takes away human body heat, accelerates sweat evaporation, and absorbs human body heat, making the human body feel cool and achieving the same coolness as natural wind.
Scope of application
A. Suitable for workshops with high temperatures or odors, such as heat treatment plants, casting plants, plastic plants, aluminum profile plants, shoe factories, leather goods factories, electroplating plants, and various chemical plants.
B. Suitable for labor-intensive enterprises such as clothing factories, various assembly workshops, and internet cafes.
C. Ventilation and cooling in horticultural greenhouses, and cooling in livestock farms.
D. Especially suitable for places that require cooling and a certain level of humidity. Various textile factories such as cotton mills, wool mills, linen mills, weaving mills, chemical fiber mills, warp knitting mills, elastic mills, knitting mills, silk mills, sock mills, etc.
E. Suitable for the field of warehousing and logistics
Installation instructions
Before installation
1. Before installing the fan, carefully check whether the fan is intact and undamaged, whether the bolts of each fastener are loose or detached, and whether the impeller collides with the fan cover Carefully inspect the fan blades or louvers for any deformation or damage during transportation.
2. When selecting the air outlet environment for installation, it should be noted that there should not be too many obstacles within 2.5-3 meters opposite the air outlet.
During installation
1. Stable installation: When installing the fan, pay attention to the horizontal position of the fan and adjust it to be level and stable with the foundation plane After installation, the motor must not tilt.
2. When installing the fan, the adjustment bolt of the motor should be in a convenient position for operation For easy adjustment of belt tension during use.
3. When installing the fan bracket, it is necessary to ensure that the bracket is level and stable with the foundation plane. If necessary, install angle iron next to the fan for further reinforcement.
4. After the installation of the fan, the sealing around it should be checked. If there is a gap, it can be sealed with a polycarbonate sheet or glass glue.
After installation
1. After installation, check if there are any remaining tools and debris inside the fan Use your hand or lever to turn the fan blades and check for any tightness or rubbing, as well as any obstructions or abnormalities that may hinder rotation. Only then can you proceed with the trial operation.
2. If there is abnormal vibration of the fan or buzzing sound of the motor or other abnormal phenomena during operation, the machine should be stopped for inspection and repaired before restarting for use.
Function
The working principle of industrial exhaust fans is actually similar to that of industrial exhaust fans. It is used in many large production enterprises. The main function of an exhaust fan is to intake and exhaust air. In some large supermarkets, factories... the role of industrial exhaust fans is still very obvious. Moreover, with the advancement of technology. These industrial exhaust fan technologies are becoming increasingly sophisticated. The noise of previous old products was a bit high, which had a significant impact on comfort. Now it's different, not only can it save electricity, but it also reduces noise and everything else. The comfort level has been greatly improved.
Nowadays, exhaust fans are widely used in industry, and the importance of product supply is also evident. When making a choice, it is important to prioritize factors such as battery life and noise, as these are key considerations. In many large occasions, the effect is particularly obvious. In order to consider the comfort of customers, it is still necessary to be cautious when choosing industrial exhaust fans.
Maintenance
Industrial exhaust fan maintenance personnel must pay attention to the following points:
1. Only operate when the fan equipment is completely normal.
2. When the fan equipment is started after maintenance, attention should be paid to whether all parts of the fan are normal.
3. Regularly remove dust, dirt, water and other impurities inside the fan and gas delivery pipeline, and prevent rusting.
4. Repairs to fan equipment are not allowed during operation.
Common sense
Industrial exhaust fans used in general environments are mainly composed of fan blades, motors, control switches, and frames.
There are two types of AC power sources for industrial exhaust fans: single-phase and three-phase. Both household industrial exhaust fans and dual-purpose industrial exhaust fans use single enclosed electric motors to adapt to harsh environments such as steam, oil mist, and polluted dust. TVs generally use ball bearings, while small-sized industrial exhaust fans that require low noise use powder metallurgy oil containing bearings.
The industrial exhaust fan motor of He is equipped with anti vibration, noise reduction, and oil storage devices. The motor operates with low noise and does not require refueling for long-term use.
The frame of industrial exhaust fans is usually made of steel plates. There are louvers on the frame that can be opened and closed.
There are many types of fan blades for industrial exhaust fans, ranging from 3 to 8 blades, and the blades should have high mechanical strength. Most industrial exhaust fans use 5 or 6 blades, which are mostly injection molded in one go, with good balance and low noise.
Installation method
Exhaust fans are generally used in low-noise, high static pressure environments to achieve ventilation and cooling purposes For different exhaust fans with different specifications and powers, users must choose according to their actual workshop situation and not blindly purchase
Before installing an industrial exhaust fan, it is necessary to determine an installation position. The confirmation of this position requires attention to the usage environment and the specific installation location, so as to achieve the desired effect of the industrial exhaust fan. When installing, pay attention to whether each fastener is installed tightly to ensure that the exhaust fan can operate normally and safely.
When installing industrial exhaust fans, special attention should be paid to ensuring smooth installation. The exhaust fan should be placed in a stable horizontal position and installed in an easy to operate position for daily use.
