There are many kinds of fans on the market. Negative pressure fans, axial fans, centrifugal fans, Roots fans, etc. are suitable for different environments, and each brand of fans is divided into fans of various performances, such as: negative pressure fans There are explosion-proof negative pressure fans, anti-corrosion negative pressure fans, stainless steel negative pressure fans, etc. What kind of environment are they suitable for? How to choose negative pressure fans in different environments? What are some good ways?

　　1. There is no special requirement for the fan for ordinary exhaust, as long as it meets the design conditions and customer requirements, it is the same for ordinary civilian fans. However, the speed of the fan generally chooses a lower speed, because the speed is too high, the overall operating noise is large, and the fan and its components are easily damaged, such as bearings and shafts, belts and pulleys, which lead to frequent replacement of parts and improve The maintenance cost. At this time, the basic negative pressure fan can be used to achieve the effect of exhaust.

　　2. There are many types of process exhaust, and some may contain welding slag, paint, explosive gas, and sometimes require high temperature, smoke exhaust, etc. Different components and different treatment methods require different requirements for fans.

　　3. Welding slag in the gas: filter screen should be added, and the motor cannot be built-in; the welding workshop or blanking workshop should usually take into account the metal swarf and welding slag contained in the exhaust gas. If these impurities enter the fan, they may scratch and wear bearing belts and other parts, and more seriously damage the motor and cause the motor to be scrapped. All requirements are equipped with a primary filter (filtering particles with a diameter of less than 1 mm) and an external motor (to prevent metal chips from entering the motor).

Energy-saving air cooler cooling effect: the cooling effect is obvious, which can reduce the indoor temperature by 4-8 degrees; PP environmental protection engineering plastics, anti-aging, anti-ultraviolet, and long service life. Whether in the R&D or production stage, we have always pursued the concept of low-carbon, environmentally friendly, green and energy-saving. That is, the dry bulb temperature at the outlet of the wet curtain water-cooled air conditioner is 5-12°C lower than the outdoor dry bulb temperature (up to 15°C in dry and hot areas). The hotter the air, the greater the temperature difference, and the better the cooling effect. Sometimes after staying in an air-conditioned room for a long time, the resistance gradually declines. Think about the so-called "air-conditioning disease".

    The water curtain + air cooler control switch should be installed indoors. Before use, ensure that there is no debris in the water curtain and the pool. Clean it 1 to 2 times a year. When not in use in winter, you need to drain the water in the pool and use plastic The cloth box is well wrapped to prevent debris from entering the machine and prevent dust. Xingke Air Conditioning has a strong core technical team, in addition to the ultimate in quality and function, it is also excellent in design. Air cooler manufacturers are truly achieving effective air supply for each position, reducing indoor temperature, and increasing indoor air circulation to greatly improve the comfort of the environment and effectively improve the work efficiency of employees. Even the products produced in some factories have a strong smell, and ventilation becomes particularly critical at this time.

    Sloth is a poor manufacturer. In view of the climatic conditions in the area where the workshop is located, the placement of production machinery and workstations, internal structure and wiring, cost input and profit expectations, etc., senior engineers of Xingke Air Conditioning will give professional design solutions to help manufacturers use the least investment to obtain The greatest benefit! There is no fate that can be conquered without contempt, endurance and struggle. Environmental protection is not a slogan, but an attitude of life that is beneficial to others and oneself; environmental protection is not a compromise, but a lifestyle of both enjoyment and public welfare. After review, several environmental protection experts agreed that: Xingke wet curtain water-cooled air-conditioning unit uses water as a refrigerant and will not cause pollution to the environment.

    Compared with ordinary air conditioners, titanium air conditioners are resistant to corrosion and aging at all times and are kept clean and efficient, so the service life is three to five years longer than ordinary air conditioners, far exceeding national standards. Performance parameters of air coolers The performance parameters of air coolers mainly include flow, pressure, power, efficiency and speed

As the concept of environmental protection, energy saving, and green emission reduction has taken root in the hearts of the people, more and more enterprises, companies and families have begun to pay attention to air coolers when choosing refrigeration equipment. Why is the air cooler high in refrigeration efficiency, moisturizing while cooling, and environmentally friendly? Today, Cool World will tell you the secrets of the air cooler.

　　 In terms of air coolers, evaporative air coolers, and air conditioners, they are actually a product between traditional compressor air conditioners and fans. It is not as cold as a traditional compressor air conditioner, but it is much cooler than a fan, which is equivalent to feeling cooler when standing on the beach or next to a waterfall.

For example, places where air coolers can be installed may not be able to install air conditioners, such as injection molding workshops, polishing workshops, heat treatment workshops, as well as some public places and vegetable markets, underground parking lots, etc.... Moreover, the investment and operating costs of central air conditioning are relatively high. It is also an important factor for many companies to choose air coolers.

The reason for this is actually like buying a car. After so many years of development in the automobile industry, my country’s family cars are not as high as they used to be. Many people can afford it, but using a car is a huge expense. . Compared with the power consumption of the central air conditioner, the air cooler saves a lot. Chengdu Kunneng's main environmental protection and energy saving product-the main motor of the 1.1KW air cooler, consumes 1/8 of the power of the traditional central air conditioner, which can be more realistic for various industries. Power saving is above 80%.

The negative pressure fan, because of its low investment, low energy consumption, and significant cooling effect, can reduce the temperature to about 28 degrees, which is consistent with the human body temperature. If the water from the well is used as the source of the water tank, the effect will be better, which can compare to the effect of air conditioning. Therefore, it is very popular among business friends, but if it is used a little longer, the noise will become louder and louder. So how to solve the problem of large noise of the negative pressure fan?

        Reason 1: When the negative pressure fan is installed, the contact with the window frame is too tight, which causes resonance of the window frame when the negative pressure fan is running.

        Solution: appropriately reduce the stuffing between the window frame and the water and air conditioner, and apply a softer material to stuff. If the bottom of the installation is not stable, the bottom should be padded and placed in a stable and firm manner.

        Reason 2: The negative pressure fan is not properly installed. The negative pressure fan should be installed in a suspended state, and the spring of the foot bolt cannot be crushed.

        Solution: Ask the maintenance personnel to adjust the installation state of the negative pressure fan to make it suspended.

        Reason 3: The vibration damping pad or fixing screw of the negative pressure fan base is screwed too tightly, and the vibration absorbing effect is lost, and vibration sound will be produced during operation.

        Solution: Adjust the screw tightness of the vibration absorbing pad of the negative pressure fan base to make the base surface level.

        Reason 4: The power supply voltage is too low, and abnormal noise and vibration are produced when the negative pressure fan starts or runs.

        Solution: Control the power supply voltage within the rated voltage range. A voltage stabilizer or a power supply regulator can usually be used to stabilize the voltage.

        Reason 5: The fan blades of the negative pressure fan collide with the fan housing (cover).

        Solution: Adjust the fan blades. Reason 6: The bearing of the fan motor of the negative pressure fan is bad, the screws on the base of the axial fan are loose, the fan blade is not fastened on the shaft, and the gap between the top of the fan blade and the cover is too small.

        Solution: Replace the bearing of the negative pressure fan motor and tighten the screws on the base and shaft of the axial fan. Adjust the distance between the tip of the blade and the cover according to the production technology requirements, generally not more than 1.5% of the length of the blade.

        Reason 7: The base screw of the negative pressure fan is loose, impeller assembly is not good, the speed is too fast, the fixing screw on the shaft is loose, etc.

        Solution: Fasten the screws on the fan base and shaft of the negative pressure fan. Reassemble and adjust impeller clearance according to technical requirements
