Roots blower can be divided into two types according to the structural type. The two rotor centerlines of the blower are in the same vertical plane, the air inlet and outlet are respectively on the side of the blower, the two rotor centerlines of the blower are in the same horizontal plane, the air inlet is on the side of the lower base of the blower, and the air outlet is on the upper part of the blower, or vice versa, that is, the air inlet is on the upper part of the blower, The air outlet is at the fan.
The left side is the intake chamber, and the pressure in the chamber is equal to the intake pressure. The high-pressure gas at the exhaust port returns sensitively and mixes with the low-pressure gas, so that its pressure suddenly jumps from the inlet pressure to the exhaust pressure. For this reason, the unevenness of the exhaust pressure of the positive displacement fan does not depend on the fan itself, but on the condition of the equipment after the gas is discharged from the fan.
Due to the filter blockage at the inlet, the impeller is severely rubbed, the gap increases too much, the belt slips, the inlet pressure loss is large, and the pipeline causes ventilation leakage. Therefore, pay more attention to the exhaust pressure of Roots blower.
Roots blower is a double blade wheel synchronous compression machine. Each three blade rotor is supported by two bearings. A pair of synchronous gears are used to keep the relative position of the two rotors constant. It is a positive displacement fan with forced gas transmission characteristics. As a rotary machine, the three blade roots blower has relatively stable working characteristics. There are small gaps between the rotor and rotor of the three blade roots blower, between the rotor and the pump body, and between the rotor and the side cover, so there is no friction and no contact wear in the working chamber; Three leaf Roots blower is economical and durable, without lubrication, with long service life and good dynamic balance. There are six suction and exhaust processes in a week of operation, with high volumetric efficiency. Simple structure, convenient use and maintenance, no need for internal lubrication, and the conveyed medium is oil-free. The support of the pump rotor adopts a reliable clearance elimination structure. The rotating parts are carefully balanced and high-precision helical gears are used. Therefore, the operation is stable, the noise is low, the use is more reliable, and the pump can operate for a long time under high pressure difference.
Roots blower adopts the most reasonable structure of three blade rotor air outlet, so water rarely enters the cavity when it is running, but many three blade roots blowers also have water ingress when they are in use, which will cause mechanical damage and even affect our normal work. In the face of this problem, we have taken a series of protective measures, These measures include the use of strict protective structure measures, the use of filter screens to prevent sludge, etc. These measures also have protective measures for the three leaf roots blower to a certain extent, but if the roots blower has water, we will dismantle the machine for cleaning, Therefore, the steps of removing the three leaf roots blower must be reasonable. Not only the water inside must be removed, but also some parts must be dried. Many internal parts of the three leaf roots blower will change after encountering water, and the internal parts will rust after encountering water. Therefore, we must pay attention to this problem in future use
1. Check whether the belt is damp. If it becomes loose, tighten it;
2. If the water quality is good and there is no suspended solids in it, the water can be drained directly;
3. Check whether the motor is damp;
4. Replace the lubricating oil, 220 # transparent gear lubricating oil;
5. If there is suspended matter in the water, be sure to clean it, and do not adhere to the impeller and other accessories;
I believe that after reading the above content, you should also have some understanding of how to deal with the problem after the Roots blower enters water. I hope it will be helpful to you.
