Disassembly steps and speed calculation of Zhangqiu roots blower
If we Roots blower It is broken and needs to be repaired. At this time, we need to dismantle it. Hongguang editor will introduce the steps of disassembly and assembly today!
1、 Head removal
Disassembly Roots blower We need to remove the head part first, that is to separate the main work of the motor and the fan;
2、 Oil discharge
Then the lubricating oil in the gearbox is extracted and the oil tank is removed;
3、 Shell removal
Remove the end cover, remove the end cover shell; remove the gear, remove the oil tank gear; remove the rotor, remove the rotor; finally, remove the impeller.
Summary: Roots blower However, before dismantling, the following points should be paid attention to:
1. Before disassembly, the assembly clearance between the components to be disassembled should be measured. For the assembly position of the key parts, such as the synchronous gear of the blower, should be recorded to avoid errors during reassembly.
2. The dismounted joint surface cushion and adjusting gasket shall be properly kept. The assembly position shall be recorded and the thickness shall be measured as the basis for assembly.
3. For some components with high assembly accuracy, such as the gear and gear ring of the synchronous gear of the blower, if the gear ring is not damaged, it is not easy to remove the bolt to make pin, because this assembly accuracy directly affects the clearance of each part of the blower.
4. For different parts, appropriate tools should be selected for disassembly, so as to avoid damaging parts, affecting assembly quality and even causing equipment not to run normally.
Synchronous gear: composed of gear ring and hub, easy to adjust impeller clearance.
4、 Calculation of rotational speed
Roots blower There are direct connection and belt connection. The belt drive is usually selected because the speed of fan and motor is synchronous, while the speed of ordinary 4-stage motor is 1480 rpm, and the cost of selecting other series of motors is high. Therefore, we generally choose 4-level motor, and the belt drive is economical and durable.
This is a problem faced by V-belt drive, Roots blower The speed of the motor is different from that of the motor. How to calculate it? It can be calculated by the following formula: motor speed * motor speed = fan speed * fan speed
From this formula, it is not difficult to see that as long as Roots blower The size of the belt pulley is constant, and the rotational speed can be found from the manual according to the requirements of flow and pressure parameters. The rotational speed of the motor is also constant, so it is easy to calculate the size of the motor pulley.
Roots blower In order to prolong the service life, the rotation speed should be reduced as much as possible under the requirements of technical parameters of flow and pressure
