Gas ring vacuum 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.

Vortex high-pressure fanPrecautions for use: Regardless of the brand of high-pressure fan, two aspects of protection are required: pressure and dust. For pressure, a pressure relief valve is often used, which is an unloading valve. When the operating pressure of the high-pressure fan exceeds the set pressure of the pressure relief valve, the pressure relief valve will automatically open to release the excess pressure and protect the high-pressure fan. For dust, filters are often used. It often uses filter cartridges with different filtration accuracies according to different usage scenarios. Different filter cartridges have different maintenance methods and service lives, which need to be clarified when ordering. In some special occasions, special protection is also necessary: for example, when using in a sealed environment, attention should be paid to ventilation and heat dissipation; When the ambient temperature (intake temperature is relatively high), it is more important to pay attention to ventilation and heat dissipation, or choose a high-pressure fan that allows for a higher intake temperature (such as a Colson ring blower that allows for an intake temperature of up to 130 ° C); For certain brands of high-pressure fans, there may be their own usage recommendations. Before purchasing, it is important to have a detailed understanding.

　　The vortex high-pressure fan 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.
