Roots blower is a volumetric blower. When in use, the flow changes little with the change of pressure. However, the flow varies with the speed. Therefore, the selection range of pressure is very wide, and the selection of flow can be achieved by selecting the speed. As the impeller of Roots blower operates in the body without friction, it does not need lubrication, so that the discharged gas does not contain oil. It is the ideal pneumatic conveying gas source for chemical industry, food industry and other industries. Before that, the precision, performance and productivity of the equipment were greatly reduced. Therefore, it is generally not allowed to use the roots blower parts to the severe wear stage. When the roots blower parts tend to the later stage of the normal wear stage, they should be repaired or replaced, and the time of this stage is also short.
1. Keep the pipeline unobstructed
During the maintenance of Roots blower, the parts on the air inlet pipe shall be cleaned and inspected; Clean the ash and oil sludge in the casing; Check whether the outlet parts and pipes are unblocked.
2. Enron valve is useful
If the ventilation is not smooth, the pressure will keep rising until the motor stops or the casing is damaged. If the enron valve opens naturally under the additional pressure or the allowed set pressure, the above fault can be solved; In this way, both equipment and personal safety can be guaranteed.
3. Ensure three gaps
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 shall be carried out according to the fan specification and model maintenance manual.
4. Pin positioning is accurate
The manufacturer reminds that there are three positions that need to be accurate, otherwise the operation of the fan will be affected. The pin of the high and low housing and the pin of the gearbox will not be replaced during maintenance, so it is only necessary to install them accurately during tempering. The gear pair is different. When changing the gear, first install and fix the gear with key, then install another gear, and lock it after excellent fitting with the connecting surface of the other gear. Turn the gear to check the contact picture of the gear surface. If there is no problem, punch the pin hole from the beginning and fine reaming, then install the pin, and then turn the gear to check the contact accuracy of the gear. If it is excellent, check the contact between the housing and the impeller The impeller and the impeller do not rub or touch.
5. Installation of pulley
The installation and alignment of the belt pulley shall be guaranteed. The corresponding belt groove shall be in the same plane and the error shall be less than 1.0mm. At the same time, the belt tightness shall be moderate, the length of each belt shall be the same, and the force shall be uniform. It is better that the thumb can move down the belt by 15m for belt tightness.
I believe that after reading the above content, you should also know what factors affect the pumping capacity of Roots blower. I hope it will help you.
