Vortex high-pressure air pumpPurpose: The high-pressure fan is mainly composed of the following six parts: motor, air filter, high-pressure fan body, air chamber, base (also serving as oil tank), and drip nozzle. The high-pressure fan relies on the eccentric operation of the rotor biased inside the cylinder, and changes the volume between the blades in the rotor slot to suck in, compress, and discharge air. During operation, the pressure difference of the blower is used to automatically deliver lubrication to the oil drip nozzle, which drips into the cylinder to reduce friction and noise, while also keeping the gas inside the cylinder from flowing back. This type of high-pressure fan is also known as a slide type high-pressure fan. High pressure fans mainly transport clean air, clean coal gas, sulfur dioxide, and other inert gases. It can also produce and transport other flammable, explosive, corrosive, toxic, and special gases as needed. Therefore, it can be widely used in metallurgy, chemical industry, fertilizer, petrochemical, food, building materials, petroleum, mining, textile, gas station, pneumatic conveying, used in chemical plants, coal mines, tunnels, boilers, canning, glass industry, ventilation and exhaust, automatic cleaning, packaging, fish pond oxygen supply, aeration, garbage decomposition, gas conveying, gas conveying, environmental protection breeding, etc. Various industrial sectors such as sewage treatment.

　　Selection characteristics:

　　1、 Definition of High Pressure Fan

　　A high-pressure fan is an air pump that generates power based on the principle of centrifugal force, also known as a high-pressure blower or vortex fan; It is commonly referred to as an air ring fan or a side flow fan in foreign countries.

　　2、 Working principle of high-pressure fan

　　After the power is turned on, the fan rotates. Due to the groove design of the impeller, it will drive air flow. Therefore, air enters the pump body through the inlet, and the air is stirred inside. Each groove is pressurized in a vortex like manner, circulating one after another, ultimately forming a strong airflow energy, which is discharged from the pump body through the outlet for use.

　　3、 Classification of High Pressure Fans

　　High pressure fans can be divided into single impeller, double impeller, and three impeller fans. As the name suggests, it is defined by the number of built-in impellers. Under the same power:

　　Pressure: single blade

　　Flow rate: single blade

　　Weight and volume: Single blade

　　Price: Single blade

　　The commonly used ones on the market are single impeller and double impeller

high-pressure blowerInstallation precautions

　　1. The vortex air pump should be placed in a relatively stable place, and the surrounding environment should be clean, dry, and well ventilated.

　　2. The rotation direction of the impeller of the vortex air pump must be in the direction indicated by the arrow on the fan casing.

　　When the high-pressure vortex fan is working, the working pressure should not exceed 8kPa to avoid excessive heat generated by the fan and damage to the air pump caused by motor overcurrent.

　　4. Except for the two bearings of the motor rotor, there is no direct contact friction in other parts of the vortex fan. The installation method of bearings for this fan is mainly divided into two categories. A type of air pump end bearing is installed in the pump body between the motor base and the impeller, and this type of air pump usually does not require lubricating grease. The bearings on the second type air pump end are installed in the middle of the pump cover, and the bearings on this type of air pump end should be regularly lubricated with grease (7018 high-speed grease). Once a month, for air pumps that work continuously in three shifts, the refueling frequency should be increased. The maintenance and upkeep of the bearings on the fan end of this type of air pump motor shall be carried out according to the first type of air pump.

　　5. The filter screens and silencing devices at both ends of the vortex air pump should be cleaned in a timely manner according to the situation to avoid blockage and affect use.

　　6. Replacement of bearings for vortex air pump: The replacement of bearings must be carried out by personnel familiar with repair work. First loosen the screws on the pump cover, and then disassemble the parts one by one according to the order shown in the diagram. The disassembled parts should be cleaned, and then assembled in reverse order. When disassembling, do not forcefully pry the impeller, use a roller to remove it, and do not miss the adjusting gasket to avoid affecting the clearance that has been adjusted before leaving the factory.

　　7. It is strictly prohibited for solids, liquids, and corrosive gases to enter the pump body of the high-pressure vortex air pump.

Vortex high-pressure fanIt has five characteristics: strong suction, high pressure, large air volume, no noise, and maintenance free. Beautiful appearance, balanced operation, easy to use, and the fan blades are made of high-strength aluminum alloy; It has dual functions of blowing and suction, and can be used for both suction and blowing. Compared to other fans, its pressure is much higher, whether it is dynamic pressure or negative pressure, it is often more than ten times that of ordinary fans!

Vortex high-pressure fanOperation and maintenance:

　　1. After installation, the air pump should be manually rotated before starting to check for any abnormal collisions or friction, whether the rotation direction of the motor is correct, and whether the inlet and outlet valves are in a low flow state.

　　2. When the air pump is running, attention should be paid to whether there are any abnormal sounds, oil leaks, abnormal vibrations, high bearing temperatures, excessive motor currents, loose feet, or other abnormal phenomena inside the fan and motor, and they should be eliminated in a timely manner.

　　3. After using the air pump, the bearing grease should be replaced.

　　4. Maintenance: When inspecting the casing, first loosen the screws on the horizontal split surface, open the upper half of the casing and the upper covers of the bearing boxes on both sides, and remove the rotor to repair the rotor or casing. During maintenance, special attention should be paid to whether the impeller blades are broken, whether there are cracks, and whether the main shaft is bent. Before installing and dismantling the machine casing, it is necessary to be careful to avoid damaging the rotor due to the swinging of the upper half of the casing during the installation and dismantling process.

　　During the shutdown period of the air pump, the inlet and outlet of the fan should be covered properly to prevent debris from falling into the fan chamber and causing accidents.

　　6. The air pump needs to be inspected every six months to remove dust and oil stains from the fan flow channel.
