Why does the vacuum of water ring vacuum pump decrease in summer


Water ring vacuum pump is a new generation product developed by our company. It has the characteristics of strong corrosion resistance, high limit vacuum degree and large exhaust capacity. So why does the vacuum drop in summer when the water ring vacuum pump is used?
1. Under working conditions in summer, water ring vacuum pump adopts circulating water to cool working water. High temperature of circulating water will lead to the decrease of suction capacity and efficiency of water ring vacuum pump. Through analysis, the working water of the water ring vacuum pump is cooled by the refrigerated water of the central air conditioner of the power plant
2. Other conditions being unchanged, the lower the working water temperature, the smaller the influence on the vacuum of the water ring vacuum pump, while the higher the working water temperature, the greater the influence on the vacuum
3. For the double back-pressure condenser, due to the low pressure of the condenser corresponding to the low-pressure condenser, it is easy to find that the limit suction pressure of the water ring vacuum pump is higher than the value of the condenser pressure, so special attention should be paid to the influence of the rising water temperature of the water ring vacuum pump on the low-pressure condenser
4. Under low load condition, lowering the working water temperature can improve the vacuum effect of condenser of water ring vacuum pump

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
