In the process of industrial water treatment, in order to speed up the aeration rate, it is usually used as an auxiliary fan facility. Strong power and low noise fans are undoubtedly the best choice. The volume of fan, the quantity of delivery and transfer are proportional to the air flow. The blade impeller rotates once and every two to three times the impeller absorbs and exhausts. Compared with the two blade impeller, the pulse gas becomes smaller, the load changes less, the mechanical strength is high, the noise is low, the vibration is small, the structure is simple, and the operation is stable. It has been widely used in many fields, including water treatment.
First of all, in the process of fan and development, find out that several water treatment fan products have good performance. Roots blower has constant torque load, saving rate and speed drop to the proportion of N%=△ N%. Although different from ordinary fans, the water pump has a high energy saving rate, but its power is large. As long as the furnace wall is not damaged, it works continuously for 24 hours and starts for a long time. Therefore, energy saving potential and cost saving are high. For the technical transformation of Roots blower, adjusting the outlet (inlet) in the past means adjusting the valve opening pressure or air production to reduce labor intensity, improve the timeliness of adjustment, improve the product qualification rate, and reduce the single consumption significantly. After the application of frequency conversion energy saving technology in cement plants, it will not only save (up to 30% - 50%) the power cost and improve product quality, but also increase the flexibility and adaptability of use. There are many different process requirements. The outlet or inlet of the hard disk will not be closed due to the wind characteristics to regulate the air flow, and the main process areas after that. After optimizing the above measures, a large number of excess air control fans can be bypassed, resulting in energy consumption of a large number of fans. Due to prominent wear and corrosion problems, the bypass valve needs frequent maintenance. It is mainly composed of air cabinet, wall panel and two impeller rotor components. The effect of a pair of synchronous gears is in the opposite direction, so that the rotor rotates at two constant speeds. The gap between the impeller and the impeller, the impeller and the housing, makes the suction chamber and the exhaust chamber basically isolated. The impeller rotates to promote the explosion under the condition of gas volume. 1. Speed
If the model of the three blade roots blower is unchanged, the speed of the roots blower can be increased to increase the air pumping capacity of the fan, which is the main factor affecting the air volume of the roots blower. The same model, the same motor power, and the speed increase can increase the air pumping capacity of the fan.
2. Model
When in use, if the three blade roots blower is far from enough in the wind, it can be provided with a replacement model to lift the wind. The disadvantage of lifting the speed is that the service life of the blower is shortened. The higher the speed of the roots blower is, the higher the wear of all parts of the blower will be, and the overall service life of the blower will be shortened.
In addition to the above two factors affecting the pumping boy of the three blade roots blower, the pumping boy of the three blade roots blower is also related to the speed and model.
1. Access to three leaf roots blower and pipeline must be guaranteed
Roots Blower During maintenance, the parts on the air inlet pipe must be cleaned and checked; The ash and oil sludge in the enclosure must be cleared; Check whether the outlet parts and pipes are accessible. 2. Enron valve is flexible, reliable and useful
Because Roots blower is a constant volume fan, if the ventilation is not smooth, the pressure will keep rising until the motor stops or the casing is damaged. If the safety valve opens naturally under additional pressure or the allowable set pressure, the above fault can be prevented; In this way, both equipment and personal safety can be guaranteed.
3. Three clearances of three blade roots blower must be guaranteed
The three clearances of Roots blower refer to the radial clearance between the rotor and the shell, the clearance between the rotor and the rotor, and the clearance between the rotor side and the shell wall. The installation and maintenance must be carried out in accordance with the specifications and model maintenance manual of the photographic Roots blower.
4. Pin positioning is accurate
As a professional manufacturer of three leaf Roots blower, we remind that there are three locations that must be accurately positioned, otherwise the operation of the blower will be affected. The pins of the high and low housings and the pins of the gearbox will not be replaced during maintenance, so it only needs to be accurately installed during tempering. The gear pair is different. When replacing the gear, first install and fix the keyed gear, and then install another one. After fitting with the other gear connection surface, lock it and turn the gear to check the contact of the gear surface
If there is no problem, install the pin after the pin hole is punched and reamed from the beginning, and then turn the machine to check the contact accuracy of the gear. If it is excellent, the casing and the impeller, and the impeller and the impeller do not rub or touch, it is OK.
5. Installation of pulley
When installing and aligning the belt pulley, it must be ensured that the corresponding belt groove is in the same plane and the error is less than 1.0mm. At the same time, it must be ensured that the belt tightness is moderate, the length of each belt is the same, and the force is uniform. It is better that the thumb can move down the belt by 15m for belt tightness.
The above is the reason that affects the pumping capacity of Roots blower. I believe you will understand it after reading it. I hope it will help you.
