　　Vortex fan, variable frequency dust collector, matched with high-pressure fan, vacuum feeding high-pressure fan

　　1. Compact structure - Made of aluminum alloy, lightweight, silent, and noiseless: The motor runs directly, and by adding an integrated sound suppression device, the high noise of the high-pressure fan is improved, achieving a silent effect. The craftsmanship is exquisite and the appearance is beautiful.

　　2. Wide performance range, flow rate up to 56m3/min, vacuum up to 100kpa, pressure up to 104kpa. The better the vacuum degree of the high-pressure fan, the less gas remains in the enclosed space, and the weaker the gas. The greater the pressure difference between it and the external environment, the higher the gas flow rate,

　　3. High reliability, cast aluminum alloy impeller and high-strength shell - simple structure with only 5 main components - base, shell, impeller, bearing, motor - sealed bearing, to prevent damage from pollutants, only one annular chamber unit to prevent thermal stress damage, dual Chen type elastic shaft seal to reduce leakage, sufficient impeller support to prevent blade breakage and blower damage, single-sided sealing gap to reduce blower failure during high-temperature operation. High pressure air pump manufacturer

　　4. Oil free transportation, no hydrocarbons carried out, and no oil and gas air supply. 5. Low noise and low temperature rise, single vortex single-sided suction impeller design, low noise, small temperature rise, with dual functions of blowing and suction, achieving dual-use of one machine, which can suck and blow air at the same time. The unique annular chamber design keeps the airflow in a stable laminar state, with low airflow noise, aluminum alloy shell, and good heat dissipation performance

　　6. High pressure blower with lightweight design, compact structure, five levels, IP54 protection level 2 motor, insulation level F, and equipped with Japanese NSK bearings. The fit between the vortex air pump shaft and the bearing should be a clearance fit to store lubricating oil and reduce wear. When the impeller rotates, it does not come into contact with any components and is free of lubrication, thus ensuring no oil or gas.

working principle

　　The impeller of a vortex air pump is composed of dozens of blades, similar to the impeller of a large gas turbine. The air in the middle of the impeller blades is subjected to centrifugal force and moves towards the edge of the impeller, where it enters the annular cavity of the pump body and circulates again in the same way from the starting point of the blades. The circulating airflow generated by the rotation of the impeller leaves the air pump with extremely high energy for use. The fan adopts a dedicated motor, with a compact structure, small size, light weight, low noise, and no water or oil in the air source sent out.

Parameter selection

　　The main parameters for selecting a vortex air pump include power, air volume and pressure (which need to be calculated with certain requirements), voltage, etc. Due to the widespread use of vortex air pumps, their selection method is the same as that of high-pressure fans. Generally speaking, the following two steps need to be followed:

　　1. Need to determine what function of the high-pressure fan is used on site, whether it is suction or blowing, and find the corresponding pressure flow curve of the high-pressure fan; If the curve is misread, sometimes the selected product cannot be used;

　　2. Based on the calculated pressure and flow rate, find the working curve above the corresponding working point that satisfies both pressure and flow rates on the curve graph; Then select the high-pressure fan model based on the working curve;

　　As long as it is a different work site, its requirements for pressure and flow rate are different, so in order to obtain relatively accurate data, relevant calculations need to be carried out. Need to consult with the technical department or relevant personnel

Application of Air Pump

　　1. Air suction function: screen printing machine suction, welding exhaust gas suction, weaving machine silk suction, photographic plate making, powder conveying, printing adsorption, industrial vacuum suction, vacuum dehydration, book making machine, residual cloth treatment, milk carton filling machine, tofu machinery, processing material retention, construction site, ironing machine, gas decomposition, etc.

　　2. Hair blowing function: gas and heavy oil spraying, bottle washing machine drying, paper and cloth strip blowing, air knife for drying, cutting machine air cushion, livestock manure fermentation explosion gas, voucher conveying, electrolyte stirring, oxygen supply for breeding ponds, convenient punching machine for taking formed products, powder particle conveying, incinerator waste discharge, smoke blowing and suction, car washing and drying, forced drying for printing machines, washing and drying, etc.

　　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 consistent with the direction indicated by the arrow on the fan casing.

　　When the high-pressure vortex fan is working, the working pressure should not be too high 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 bearing on the air pump end of this fan is installed in the pump body between the motor base and the impeller, and this type of air pump does not require lubricating grease during normal operation.

　　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 dedicated 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.
