Negative pressure fan is a synonym, with negative pressure for exhaust and positive pressure for exhaust. Negative pressure fans are widely used in areas such as factory ventilation and greenhouse aquaculture, with excellent results. The advantages and disadvantages of negative pressure fans include the size of exhaust air volume, sound level, energy consumption, and service life.

Recently, the market for wind turbine models was uneven, and the market prices were also very chaotic; This mainly includes traditional white iron sheet fans, fiberglass shell three leaf fans, and other categories, with different specifications, technical parameters, and production materials from each household. However, generally speaking, the above two types of fans belong to traditional fans, most of which are used in greenhouses and animal husbandry.

Given that traditional white iron sheet fans have always had defects such as high equipment failure rates and increased customer maintenance costs. The three leaf fan with a fiberglass reinforced plastic shell also has a defect of particularly high sound exposure. In order to comprehensively improve the application of negative pressure fans in factory ventilation, our company is focusing on improving the direct connection transmission system, seven leaf and nine leaf negative pressure fans, which can effectively reduce noise and maintenance costs; Achieve characteristics such as high oil and air volume, low volume, high efficiency, and long service life. It can be said that the negative pressure fan is truly efficient in environmental protection.

Industrial electric fan is a type of fan used in industry, which can also be used in public places. But is the industrial fan effective during use? Perhaps for those who haven't used it before, they may not be very familiar with it. So, let's briefly introduce each part of the industrial fan:

1. Form and Design: Communicate driving force, speed, rolling speed and circular speed ratio, gear modulus ratio, shaft reference point, tooth material, and homogeneity of raw materials.

2. Production and manufacturing: precision of gear system production and manufacturing, precision of gear tooth surface, heat treatment process, hardness.

3. Gear housing (oil baffle): stiffness or strength, thermal expansion, oil volume.

4. Control standards: speed, load, vibration caused, ambient temperature, and exposure to external heat.

5. Raw material compatibility: steel, non-ferrous metals, non-metallic materials, plastics, paint coatings, etc.

The above are the functions of each part of the industrial fan, hoping to be helpful to everyone.

The compressor plays an important role in refrigeration in the air cooler. The compressor is the core component of a cold air fan, mainly by reducing the refrigerant and converting it into a high-pressure and continuously high-temperature vapor. At this point, the energy of the refrigerant increases, which can effectively absorb heat.

Next, the high-pressure and high-temperature refrigerant releases heat from the cooler and becomes a high-pressure and low-temperature substance. Subsequently, the refrigerant enters the air conditioning evaporator through the air conditioning expansion valve, causing a sharp decrease in temperature and pressure throughout the surge process. At this time, the refrigerant absorbs heat from the air, causing the air to cool down.

Therefore, the compressor plays a role in reducing the refrigerant in the air cooler, enabling it to absorb, transport, and release heat during the cycle, thereby achieving the actual cooling effect in the air.

When cleaning the air conditioner, it is necessary to first remove the wet curtain and unscrew the three screws on the upper part of the wet curtain; Holding the upper blind of the wet curtain in your hand, gently pull it outward and then lift it slightly upwards to remove it;

Then remove the cover of the air cooler and the water distribution pipe assembly. First, unscrew the screws inside the cover, and then lift the cover up to get it; Loosen the hose clamp in the water supply pipeline and loosen the water supply pipeline. Lift up the total length of the water distribution pipe and take it.

Next is the cleaning of the hardware and electrical components of the cold air fan car chassis, which are all methodical. For example, a soft cloth or brush can be used to clean the car chassis; Clean the fan blades with a soft cloth, and remember not to let dust from the fan blades fall into the air duct. Cleaning the water level sensor can use a small damp cloth to remove any dirt from the water level line;

Cleaning the water pump: You can use a brush to clean and tidy the dirt in the water pump and filter screen; Clean the laundry drain valve and pay attention to the stains on the bottom of the drain valve. After cleaning all components, there are also wet curtains and filters for cleaning.

Clean the wet curtain of the air conditioner from the inside out with warm water, and the filter can be removed and cleaned once a week; Twist off the back cover of the filtering device, clean the dirt in the filter element, and then install the back cover; After cleaning, follow the disassembly process in reverse order and reinstall the entire equipment to restore its original function.
