Swing fan, factory direct prices

Kai genuine rotary fan / blower for low noise sewage aeration project, HCC rotary fan, otherwise known as HCC swing fan, fan and other vane, fan with low noise and environmental protection, manufacturers direct, fans all models, fan spot, price high, three bags a year, life-long service! Model is complete: HCC-20S HCC25S HCC30S HCC40S HCC50S HCC60S HCC80S HCC100S HCC-125S HCC-150S, the company can be customized according to user needs fans, mostly individual motor and three motors to meet different customer needs power. HCC rotary blowers widely used, mainly to meet the customers' needs for low noise fan: Households wastewater treatment aeration; industrial wastewater aeration stirring; vacuum feed printing industry; plating tank, industrial wastewater aeration stirring; plastic welding, gas supply of food packaging hair; the burner spray, glass industry and others. Small wind turbines are becoming an alternative product of choice for small blower. HCC rotary blowers its compact structure, a pressure fan, fan pressure range: 0.1-0.5kgf / cm2. Wind range 0.2-10.2 cubic per minute. The main part of the rotary fan has six, namely: motors, air transition, a blower body, the air chamber (and oil separator function), the base (and tanks), drip nozzle (controlled drip rate, easy to maintain fan ). Rotary fan biased against the inner cylinder rotor / vane eccentric operation, and volume change blade rotor slots between air suction, compression, spit. The blower pressure difference in the operation automatic lubrication to drip nozzle inner cylinder was dropped to reduce friction and noise while maintaining the cylinder of gas is not reflux. With the development and progress of society, people pay attention to the cause of environmental protection at every step, in sewage treatment, various rotary fans have also been gradually recognized by the environmental protection industry and people, in order that we can better use the rotary fan, Let us look at the rotary fan must be used to note about the issues now. 1. The pipeline flow problem: Pipeline flow rate should be controlled at 16m / s or less, the faster the flow rate, the larger the pipe network resistance may lead to a surge blowers, rotary blower load added. 2. The quality of aerators in the domestic market a wide variety of mixed quality, the price span. Due to the lack of industry standards association, artisanal mode of production over the present. For example, in terms of rubber diffusers, each by the use of raw materials and ingredients are not the same, leading to an unstable product quality, such as adding an excess of carbon black, rubber hardens, the resistance increases; add the lack of carbon black, rubber board too soft, then simply break; and even there using recycled rubber and other conditions. Therefore, the non-industrialized production of the product, its quality is difficult to control. If the aerator release amount (volume and depth of the release, pressure, flow rate, film quality are contact aerator) can not reach the process requirements, leading to the release of the rotary fan flow rate <70%, it will attack the surge and add Fan pressure. 3. The use of check valves divergent: various manufacturers produced a check valve in the extension spring hardness divergent ,, some resistance will not necessarily be lost, if the loss is greater than the whole piping resistance rotary fan outlet pressure, will show asthma vibration. When the rotary fan is switched off, it must first import butterfly valve closed, and then closing the outlet valve, it is entirely possible to prevent the pouring issue, without the outlet end of the valve. Add a missing check will increase resistance, add equipment costs and working costs. 4. The ambient temperature change based on fan industry standard, rotary blower portrayed temperature is 20 ℃, every increase of 1 ℃, outlet pressure will fall about 20mmH2O. For example, the summer temperature is 38 ℃, the outlet pressure will drop 360mmH2O. The company based on our most regions throughout the hot summer climate characteristics, the rotary fan inlet end depict temperature progress to 37 ℃, that is the same as shaft power at the outlet end pressure higher than the national standard 340mmH2O. Depending on the specific situation of the use of the site, during the rotary fan selection, but also thinking of the influence of temperature changes in the fan outlet pressure. When the fan to day use limit temperature Tmax> 37 ℃, press 20mmH2O / 1 ℃ on the intake side pressure compensation. 5. With regard to changes in altitude pressure rotary blower depicted 98kpa (altitude 150m, 1atm). When the fan using the address of the altitude h> at 150m, should the outlet pressure and inlet flow rate for proper compensation, to ensure that the device is working properly. 6. grid problem: When two or more rotary fans and network, it is necessary to think and network add resistance. Some users in the use of conventional single wind turbine works fine, but two or more rotary fans and showed a lack of air flow when the net, do not increase the motor current appearance, which can supply a whole, aerators planning, It can release to synchronize pipeline equipment and other factors related to whether reasonable. 7. Sewage fan vent valve in parallel using multiple turbines ,, only means a vent valve. When the fan starts, if not yet opened aeration head, it can open the vent valve, vent some gas, the blower to reach a certain flow, until smooth and then boost the vent valve closed. This can handle a pressure go up due to low traffic surge problems. Xiao Bian hope the above description that we can be helpful, our company is the design, production and sales of rotary fan of professional manufacturers, the products sell well all over the country, rotary fans supporting the export of some products. We produce excellent quality rotary blower, products available from stock, the quality of three bags a year, at reasonable prices. Company wholeheartedly with all the friends together for a better future, we believe we can have a better future!
