What are the maintenance skills of Roots blower?

As for Roots blower, it is a relatively sophisticated equipment in the cement industry. Due to its high pressure and hard working characteristics, the shell explosion and collision may occur, which is very dangerous and must be paid great attention. Here are some key skills that must be mastered in the maintenance of Roots blower.

1. Ensure the smoothness of roots blower and pipeline

During the maintenance of roots blower, the parts on the air inlet pipe must be cleaned and inspected; Clean the ash and oil sludge in the casing; Check whether the outlet parts and pipes are unobstructed.

2. The valve is flexible and reliable

Because Roots blower is a constant volume fan, if the ventilation is not smooth, the pressure will continue to rise until the motor stops or the casing is damaged. If the * * * valve opens naturally under the rated pressure or the allowable set pressure, the above fault can be avoided; In this way, both equipment and personnel can be guaranteed.

3. Three clearances of Roots blower must be ensured

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. Installation and maintenance must be carried out in accordance with the relevant Roots blower specification and model maintenance manual.

4. Pin positioning is accurate

The manufacturer of Roots blower indicated that three positions must be accurately positioned, otherwise the operation of the fan will be affected. The pins of the upper and lower housings and the pins of the gearbox are basically not replaced during maintenance, so only correct installation is required during maintenance. The gear pair is different. When replacing the gear, first install and fix the keyed gear, then install another one, and lock it after it fits well with the joint surface of the other gear. Turn the gear to check the contact condition of the gear surface. If there is no problem, re punch the pin hole and finish reaming, then install the pin, and then turn the gear to check the contact accuracy of the gear. If it is good, the casing and the impeller, and the impeller and the impeller do not rub, That's all right.

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 the same. The belt should be tightened when the thumb can move down about 15mm by pressing the belt.

The above content explains the key skills to be mastered in the maintenance of Roots blower, and I hope it can be helpful to you.
