Sewage blower ZXSR-efficiency blower selection is based on many years of manufacture and sale of environmentally friendly wind turbines on the introduction of new products and new technology development. This machine by using the new line to the impeller, bringing the total adiabatic efficiency and volumetric efficiency is further improved air flow and pressure characteristics are particularly good fan. The so-called good efficiency, the fan itself is relatively less heat on the appreciation that the temperature drop, the exhaust pressure is the force of various models in use in dry conditions up 0.6kfg / square cm ZXSR-efficiency blower features: 1. Spiral shape is fixed above 20 ℃ helical fashion. Into the exhaust shield casing spiral cut, smooth the top line of a triangular configuration of the rotor into the exhaust port, through the rotation of the rotor and sequentially opened. The inlet and outlet of the fan, not as open as the old spiral Roots blower in an instant or closed, so the sound operation is extremely small, almost no exhaust pulsation. 2. Because the rotor is clover rectilinear, so it does not like helical rotors as a result of slight axial displacement of the rotor in contact with each other. Therefore, only to ensure that the gap between the rotor in profile, is no longer necessary as plus spiral rotor axial displacement, so that the gap is too big this fan efficiency than the same size rotor helical fan better. 3. Due to take special shape of the rotor, the rotor is easy to keep a gap between each other, so that efficiency is further improved. 4. The use of precision CNC machine tools production rotor, and the accuracy of management has taken measures to improve, so there is no error between the performance of wind turbines. Also, turn on in the manufacturing process is rigorously balanced, so the machine vibration is minimal. 5. High-precision drive gear, not only the life has been extended, and to achieve a low noise. 6. Output clean air, free of any oil. Inside the enclosure do not need oil lubrication, and avoid using bearings, gears, oil mixed with the internal structure of the chassis design. ZXSR-efficiency blower works: ZXSR-efficiency blower to overcome the original old blower * end the existence of the old two-leaf type, trefoil, the compression principle is to exhaust the rotor tip instant mouth open line, air vents inside the chassis of the high-pressure air counterflow, compression, this countercurrent with a dramatic compression pressure changes in legislation, this pressure change causes of the formation of the fan noise. The fan in order to eliminate such factors studied spiral shape, so as to achieve the effect of energy saving and environmental protection Zhang Xing Machinery Co., Ltd.
