For the negative pressure fan, what are the reasons for its operating noise? How to take necessary and effective measures for different reasons? During the operation of the negative pressure fan, how to avoid this problem? Today we will give a specific answer to let everyone Understand and master, apply it to practice. Ningbo air cooler, Ningbo air cooler

　　 1. If the negative pressure fan is installed, its contact with the window frame is too tight, causing the window frame to resonate during operation, then it should be properly adjusted its tightness, or stuffing. For the bottom of the negative pressure fan, check whether it is stable, if it is not stable, then it must be dealt with. In addition, the spring of the anchor bolt cannot be crushed to avoid problems.

　　 2. On the base of the negative pressure fan, the tightness of the vibration damping pad or fixing screw is too high, so that it loses the vibration damping effect, resulting in vibration. At this time, the vibration damping pad or fixing of the negative pressure fan base should be dealt with. The tightness of the screw is adjusted to make it suitable to restore the vibration reduction effect.

How to solve the operation noise of negative pressure fan?

　　 3. The equipment power supply voltage is too low, which makes the fan appear abnormal noise or vibration. The solution is to control the power supply voltage within the rated range and install a voltage regulator to stabilize the voltage. In addition, if there is collision or friction between the fan blades and the casing, it will also cause this problem. Therefore, the distance between the blades and the casing should be adjusted and controlled to avoid problems.

　　 4. In the negative pressure fan, if the impeller assembly is not good, or the speed is too fast, it will also cause operating noise. Therefore, to deal with it, the specific method is to reassemble the fan according to the technical requirements and adjust the speed of the impeller to make it within the appropriate range.

Why is there a wide disparity in the cooling effect of industrial chillers?

    When it comes to industrial air coolers, there are countless manufacturers of industrial air coolers in my country. Of course, with the difference of manufacturers and materials, the cooling effect of industrial air coolers also varies greatly. Let's talk about it to our professional manufacturer, Ruitaifeng, why are all industrial air coolers, but the results are very different? Ningbo air cooler, Ningbo air cooler

 

    Why is there a wide disparity in the cooling effect of industrial chillers? Product selection is very important, that is, product quality. After all, the ship made of paper is very different from the ship made of wood. Ruitai Fengrun Dongfang independently developed a low-vibration, corrosion-resistant all-copper core motor, which runs more smoothly and has a very low failure rate; the self-developed integrated bow blade forward swept blade, the blade is not deformed or broken under heavy pressure, and has a long life , Large air volume; Carefully selected solid PP environmental protection engineering plastic shell, new special environmental protection engineering anti-aging plastic, good toughness, anti-aging, anti-ultraviolet, normal service life can reach more than 10 years, good things naturally good effect

     Of course, don’t forget, the most important point is the brand. The brand of industrial air coolers is also very important, because the brand not only represents high quality, but also high service. After all, equipment products will inevitably appear small. Problems, so after-sales service is particularly important. Good industrial air cooler brand, what are you waiting for? Call us now.

What type of negative pressure fan is suitable for use in the greenhouse?

　　Now the negative pressure fan we produce is mainly used for the ventilation system inside the greenhouse. It can be said that the negative pressure fan is an indispensable component of the ventilation and cooling system inside the greenhouse.

　　Now the intelligent greenhouse is generally equipped with a negative pressure fan of more than 1380mm model, mainly to cooperate with the overall air environment inside the greenhouse to achieve the effect of ventilation and cooling.

In general, it is not enough to install negative pressure fans inside the greenhouse. It is also necessary to carry out supporting cooling curtains, so that the overall air environment in the greenhouse, the temperature, humidity, etc. in the greenhouse can be adjusted in the overall environment, which plays a good intelligence. The effect of greenhouse temperature control.

What type of negative pressure fan is suitable for use in the greenhouse?

　　 So we need to understand the configuration of negative pressure fans in the solar greenhouse today. Generally, the solar greenhouse is mainly used for heat insulation in winter, but the ability to understand the temperature through the windproof system in summer is still limited. Therefore, we need to construct vents on both sides of the solar greenhouse, a negative pressure fan on one side, and a water curtain cooling system on the other side, so that it can achieve a good summer cooling effect.

Then what diameter should we configure, and how many types of negative pressure fans should we have? This requires the actual situation of our greenhouse. If the greenhouse span is large and the wall area is large, we can configure several large negative pressure fans, such as 1380mm-- 1530mm negative pressure fan. If the solar greenhouse has a small span and cannot install a large negative pressure fan, we can only configure multiple small negative pressure fans. For example, a 1000 by 1000mm negative pressure fan is a very good choice.

One of the important website products and main keywords of the air cooler should be taken seriously in its learning attitude, and in terms of learning requirements, it must be comprehensive, so that it can be used correctly and reasonably. Cooler, and at the same time, to get good results. Therefore, based on this, next, we will carry out the knowledge explanation work in this area, so that everyone can master and apply it in time.

1. If the air cooler in the cold storage is frosted, is it necessary to carry out defrosting work?

     If the air cooler in the cold storage has frosting phenomenon, then it is necessary to carry out defrosting work, otherwise, the air cooler cannot work normally. In addition, the defrosting method can be either manual defrosting or mechanical defrosting. As to which one is selected, it depends on the actual situation and is determined by it.

2. In terms of air coolers, how can they be classified?

     In general, air coolers can be divided into two types: household air coolers and industrial air coolers. If it is a household cooler, it is mainly used to reduce the indoor temperature in summer, and industrial coolers, which are generally used in refrigeration equipment, are an important part of refrigeration equipment. For example, they can be used as cold storage internal machines .

3. How to deal with the overcurrent protection of the cooling fan?

     The overcurrent protection of the air cooler is a protection mechanism of the air cooler, indicating that the current in the machine equipment exceeds the specified limit, and the equipment has a fault problem. At this time, the operation of the air cooler should be stopped immediately and carried out Check the work in order to find the problem and solve it in time, so as to avoid the adverse effects or consequences.

     The above-mentioned questions are all about the air cooler, and at the same time, they are also related to the website products. Therefore, I hope that everyone will take it seriously and carry it out in order to master it in time, so that it can be well used in actual work and at the same time, to improve the use of the product, so that you can benefit from it.
