Advantages and Disadvantages of Vacuum Pump System



Compared with other types of mechanical vacuum pumps, the vacuum system water ring pump has the following advantages:
The structure is simple, the manufacturing accuracy is not high, and it is easy to process.
Compact structure, high pump speed, generally can be directly connected with the motor, without deceleration device. Therefore, with a small structure size, we can get a large amount of exhaust gas and occupy a small area.
Compressed gas is basically isothermal, that is, the temperature change of the compressed gas process is very small.
Because there is no metal friction surface in the pump chamber, there is no need to lubricate the pump, and the wear is very small. The sealing between the rotating part and the fixing part can be accomplished directly by the water seal.
Inhalation uniformity, stable and reliable work, simple operation, easy maintenance.
Water ring vacuum pump also has its shortcomings: low efficiency and low vacuum.
In short, because the gas compression in the water ring vacuum pump is isothermal, it can extract flammable and explosive gases. Due to the absence of exhaust valves and friction surfaces, dust-laden gases, condensable gases and gas-water mixtures can be removed. With these outstanding characteristics, it has been widely used in spite of its low efficiency.

Reasons and Solutions for Fragile Belt of Roots Blower

图片
1. Reasons for easily broken belt of Roots blower: 1. First of all, consider the high speed and high temperature of Roots blower. 2. The distance between the head and motor of Roots blower is too large and the belt is tight. 3. The belt does not match the V groove of the pulley, so it can not withstand the load fracture after wearing. 4. Active pulley and driven pulley are not parallel, resulting in serious friction between belt and groove on one side, and can not bear load fracture after wear. 5. Heavy load, long-term overload operation of belt is easy to break. 6. Roots fan nose and motor pulley are not concentric, different axes. 7. Belt quality problems. 2. Measures to prevent the belt of Roots blower from breaking. 1. Roots blower must start without load before running. After starting, it should be loaded. After running, it can generally avoid triangular belt breaking. 2. The pulley between the motor and the fan should be parallel, which is a key point. If not para
