Vacuum pump smoke and fuel injection


Next, I will analyze and deal with the phenomenon of smoking and fuel injection for everyone.
1. Smoke: If the vacuum pump has just started to run, there is a smoke phenomenon, which is normal. If it is smoked for a long time, it is not normal. This means that the outside of the air inlet of the vacuum pump, including the repair of pipes, valves and containers. After the leak detection, the smoke will end.
2. Injection: This indicates that there are a large number of leaks outside the inlet, and even the inlet is exposed to the atmosphere. At this time, we need to seal the air inlet of the vacuum pump to make the vacuum pump run. If there is no fuel injection, it indicates that there is a leak; there is damage to the exhaust valve, check whether the exhaust valve is damaged, and replace the bad exhaust valve. .

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
