Centrifugal fan is a disorderly equipment, mainly composed of air inlet, damper, impeller, electromechanical and air outlet. In the different state, the influence of the centrifugal fan is not the same. Therefore, some different operating conditions are not the same, and the influence of the centrifugal fan will be affected. Debugging the centrifugal fan to its optimum state can be used in many ways. Yuyao air cooler, Cixi air cooler

     1. The centrifugal fan allows full-voltage starting or step-down electric, but it should be stable. The current at the full-voltage starting is about 5-7 times the extra current. The step-down starting torque is proportional to the square of the voltage. When the grid capacity is lacking. , should use the buck start.

     2. When the centrifugal fan is in the test run, it should read the commodity imitation list and check whether the wiring method is consistent with the wiring diagram; it should be checked whether the power supply voltage supplied to the fan power supply is in compliance with the request, whether the power supply is phase loss or phase. Whether the capacity of the electrical components is in compliance with the request.

     3. The number of people in the test is not less than two. One person controls the power supply. One person inquires about the state of the wind turbine. The invention is very weather-stop and immediately shut down. Check whether the twisting bias is accurate. When the centrifugal fan starts to start, check the various things immediately. Whether the current is equalized, whether the current is beyond the extra current; if there is no abnormal weather, it should be stopped for inspection. After five minutes of things, stop the machine to check if the fan is very meteorologically.

     4. When testing the two-speed centrifugal fan, start the low speed first and check whether the torsional deflection is accurate. When starting the high speed, it is necessary to mobilize after the end of the fan to prevent the high speed reverse torsion, causing the switch to trip and the electromechanical damage.

     5. When the centrifugal fan reaches the abnormal speed, it should measure whether the output current of the fan is abnormal. The running current of the centrifugal fan can't exceed its extra current. If the operating current exceeds its extra current, check if the supplied voltage is abnormal.

     6. The electromechanical power required for the centrifugal fan means that under certain working conditions, the power required for the centrifugal fan breeze chassis and the air inlet is fully open. If the air inlet is fully open to stop things, there is a danger of damage to the electromechanical device. When the wind turbine is tested, it is best to close the valve at the inlet of the fan or the inlet pipe. After that, the valve will be drooped to open the hole to reach the end of the required working condition, and whether the current of the fan is exceeded.

     Strictly follow the above-mentioned debugging method to stop the commissioning of the centrifugal fan, which can make the power of the centrifugal fan reach 98% or more.

The development of technology has brought about the upgrading of electronic products, so now the use of air conditioners is no longer the fashion that the masses follow. The chillers are gradually entering our sights. The chillers use groundwater as a circulation and use water pumps in the summer. The water is pumped up, through the indoor fan coil to achieve the purpose of refrigeration, the return water flows back to the ground through the pipeline, and in winter it is used to warm, which has replaced the market share of air conditioners. Yuyao air cooler, Cixi air cooler

1 Cooling fast: The cooling effect is not affected by the hot weather, and the hotter the weather, the better the cooling effect. The flow rate of the refrigerant is large, and the heat exchange area of ​​the evaporator is large, and the process from the high temperature to the comfortable temperature is faster than that of the general air conditioner.

2 High efficiency: using gas-water separation technology to increase the density of water and improve the water temperature transmission efficiency, combined with the special evaporator to make full use of natural cold air, the air-conditioning outlet temperature is close to the inlet water temperature, and the equivalent water temperature can be reduced by 4-5. °C.

3 No noise: The water flow noise is completely eliminated by the gas water separator.

4 Power saving: only the general air conditioner 1/10--1/25 power consumption, low power consumption and low cost, is affordable and affordable air conditioners that can be afforded by the family.

5 No pollution: no Freon refrigerant, no chemical pollution, no waste heat and waste, it is a natural and environmentally friendly product.

The air cooler not only has the above advantages, but also has superior air purification capability, and constantly produces negative ions, which makes you feel as comfortable as living in the forest, and even less air-conditioned.

The cooling air cooler is cooled by the action of water. Under the action of water circulation, it can effectively improve the humidity of the air, instantly cool the air and make the environment fresher. The function of the air cooler is remarkable, and the five major realms let you hold it. Yuyao air cooler, Cixi air cooler

1, efficient cooling

The vacuum cooling system of the negative pressure air cooler uses the cooperation of the fan and the water curtain to artificially reproduce the physical process of evaporation and cooling of the natural water. The power consumption is only one tenth of that of the conventional air cooler.

2, ventilation and ventilation

Under the cooperation of the whole system, the exhaust negative pressure fan quickly removes the hot air, exhaust gas and odor generated by the indoor personnel and the machine, and avoids the stimulation of the human body by the exhaust gas and the odor. The entire indoor air can be updated in one minute at the earliest, which is not possible with ordinary air coolers.

3, improve work efficiency

The cooling chiller solves the problem of sultry heat and insufficient oxygen, which increases the attention of workers. The use of air-cooling fan products can not only solve the problem of sultry heat in the plant, but also generate negative ion oxygen while evaporating and cooling the water. Increasing the oxygen content in the air can adjust the mood and relieve fatigue to improve work efficiency.

4, health and environmental protection

The system uses water as a refrigerant, which has no pollution to the environment during manufacture and use. In addition to reducing the humidity of the air, the cooling of the chiller has the dust and particles carried by the external air. The efficient circulation of fresh air can effectively prevent the infection of occupational diseases and circulating diseases.

5, strong applicability

The air-cooling system of the air-cooling fan type factory has wide applicability, and various places are crowded, and the heat source is large, or the place which is easy to produce pollution and poor ventilation can exert remarkable effects. For example, textile workshops, garment workshops, injection workshops, hardware factories, shoe factories, electronics factories, etc., can design corresponding systems according to their different environments, and use the air cooler to adjust different wind speeds according to the specific conditions in the room. The air volume is very flexible.

First, the fresh air coefficient is high, the air quality is good. When the traditional compressor-type air conditioner is running, the doors and windows need to be closed to keep the indoor temperature unchanged. Because the doors and windows are closed, the fresh air entering the room is less, the indoor air exchange frequency is low, and the air quality is poor. Dizziness, headache, and physical discomfort; the company's production workshop has high indoor temperature in summer, and poor air quality, especially in workshops that generate harmful gases. If closed cooling is performed, it may even cause poisoning, and it is for human body and enterprise production. Causes adverse effects. The core component of the evaporative air cooler is an evaporative wet curtain, which is characterized by good water absorption and ventilation performance, firm texture, water immersion without deformation and corrosion resistance. By designing a special corrugation angle, the water flow can flow directly to the side of the air inlet, and when the fresh air passes through it, the water and the air can be fully contacted. This not only improves evaporation efficiency, lowers temperature, but also effectively filters out harmful substances and dust in the air. When the evaporative air conditioner is running, the doors and windows are open (when the exhaust system is installed, the doors and windows may not be opened.), it is not necessary to self-circulate the old air in the room, but always provide sufficient fresh and natural cold air, the fresh air coefficient is high, and the air quality is good. The human body does not cause damage and is conducive to normal production. Yuyao air cooler, Cixi air cooler

Second, energy saving and environmental protection In terms of environmental protection: Central air conditioning has a great impact on the environment. For example, the chloride ion in Freon has a destructive effect on the ozone layer of the atmosphere. The condenser in operation also continuously dissipates heat, while the evaporative air conditioner unit is It has no compressor, no refrigerant, no pollution and environmentally friendly products, and it does not radiate heat to the surroundings. In terms of energy conservation: in the same process conditions and air-conditioning area, central air-conditioning energy consumption is large and wasteful; installation of evaporative air-conditioner units can effectively save energy, and the economizer air-conditioner unit consumes only central air-conditioning. 15~50%, this can not only reduce energy consumption for enterprises, but also save operating costs, save energy, and reduce production and work due to power shortage.

Third, humidity adjustment In some dry indoor humidity adjustment, or some places that need to humidify, the traditional compressor-type air conditioner needs the corresponding humidity adjustment facilities; and the evaporative air-conditioner unit can be equipped without humidity adjustment facilities, the unit can Adjust the air humidity by yourself to meet the needs of the production process.

4. Small footprint, simple installation and convenience In the same process conditions and air-conditioning area, the installation of traditional compressor-type central air-conditioning requires a dedicated machine room, which covers a large area; and the evaporative air-conditioner unit is mainly installed on roof and wall brackets. The upper or indoor computer room has a small footprint, which is about 90% less than the installation of the traditional central air-conditioning. Some evaporative air-conditioner units do not occupy any building space. The central air-conditioning system consists of chillers, cooling towers, cooling water pumps, and end devices. It is troublesome to install, and the evaporative air-conditioner unit does not require equipment such as chillers, cooling towers, cooling water pumps, and end devices, so the system is simple to install. Fast.

V. Stable performance, reliable quality and convenient maintenance. The traditional compressor-type central air-conditioning structure is more complicated, requiring professional operation and maintenance, and the maintenance cost is large. The evaporative air-conditioner unit is equipped with automatic electronic control and automatic cleaning function. The equipment performance is stable, the noise is low, the efficiency is high, the product quality is reliable, the operation and operation management is convenient and simple, no professional operation is required, the maintenance is simple and convenient, and the cost is low.
