1. Yüngül çəki
Compared with the same type of blower, the weight is 30% lighter.
2. Aşağı səs
The noise of the blower body is less than or equal to 84dB(A), and it is high-frequency noise. When there is no soundproof room, the propagation distance does not exceed 20 meters
3. Kiçik vibrasiya
Under operating conditions without any vibration reduction device, the radial (bidirectional) vibration speed of the blower bearing seat is ≤4.0mm/s.
4. No mechanical friction
When the blower is running, there is no mechanical friction between other parts except the bearing, which reduces the noise and ensures the service life.
5. Oil-free machinery
No oil or gas is generated during the operation of the blower, and the aerator is not corroded, which prolongs the service life of the aeration system.
6. Shaft temperature digital display sound and light alarm
The front and rear bearing housings of the fan body are equipped with thermocouples, and the ports are connected to a digital display to display the shaft temperature. The temperature of the bearing will rise due to lack of or overfilling of grease, oil, or wear. When the set temperature is exceeded, the sound and light alarm will automatically alarm.
7. Asan texniki xidmət
Since the centrifugal blower is a frictionless machine, the rotor is supported by the front and rear bearings, and the casing and impeller are not easily damaged. Daily maintenance is mainly to ensure the effective lubrication of the bearings and temperature monitoring. Normally, only the replacement of bearings and couplings is required. Stud. The blower casing adopts a series connection structure (similar to a string of candied haws), the front and rear bearing seats are independent, and the external (connected with bolts) are connected to the intake and exhaust volute. When repairing, there is no need to disassemble the whole machine, just unscrew the connecting bolt and remove the bearing seat to replace the bearing, saving time and convenience.
8. Case water cooling
For the blower whose pressure is higher than 8mH2O, because the temperature at the outlet end must exceed 160℃, a cooling spacer is added to the outer layer of the casing (stator), which can reduce the gas temperature by more than 40℃, effectively increasing the blower’s pressure rise Efficiency and overall work efficiency. The water source can be connected in series with the water cooling device of the bearing housing. The water consumption is less than 1.5m3/h, and the water consumption cost is much lower than the electricity cost saved due to efficiency improvement
9. Inverter control
For a blower equipped with a 380V low-voltage motor, a frequency converter can be used to increase the power frequency and increase the speed to 3600rpm, thereby increasing the blower efficiency to 80%. After frequency conversion, energy consumption can be greatly saved. In particular, the booster and flow rate adjustment range of the blower can be larger, and the application range of the unconstant water level such as SBR is wider. It has the advantage of flushing due to partial blockage of the aerator, especially the blower below 45m³/min can reach about 11mH2O Boosting effectively solves the problems of small flow and high pressure processes such as deep well aeration.
10. Quraşdırmaq asandır
The complete blower is delivered from the factory. The main engine and the motor are fixed on the same steel base. There is no need to add other damping devices in the installation, and the requirements for the installation level are not high. The filter muffler at the inlet of the blower can be directly installed on the blower; and the outlet pipe must be connected to the blower through a flexible joint to prevent the gravity of the pipe and the additional force of installation from directly acting on the blower.
11. The rotor is manufactured with advanced technology
The impeller uses finite element theory and adopts quasi-three-dimensional (ternary flow) design. The impeller is made of high-quality aluminum alloy by centrifugal casting; stable and reliable performance, ensuring the strength of the impeller under high-speed operation, so as to ensure the longest service life of the impeller. Because the impeller line is reasonable and well made, the blower efficiency reaches 78%, which saves a lot of energy and reduces operating costs.
12. Rear bearing housing water cooling
In the process of blower, due to the compression of air, the temperature of the final casing is generally higher than 80 ℃, and the temperature of the Xia Li can be higher than 100 ℃, so the bearing seat cooling needs to be considered. In the original design, the rear bearing seat air-cooling system has been installed, and now we are innovating on this basis, adding a water-cooling system, realizing the dual insurance function of the rear bearing seat and extending the service life of the bearing. The quality of the cooling water is not high, tap water, reclaimed water, or even preliminary treated sewage can be used.
